The measures are included in the "California Urban Water
Conservation Council Best Management Practices Retail Water
Agency Annual Report." See Appendix.
Several of the District's large-scale conservation programs are
listed here with a brief description, references to the Best
Management Practices Report (BMP), and an evaluation of the
impacts as required in this section. Except where noted, all
programs are currently operational.
Note: The material included in this section is also used to meet
required data for Chapter 3, Section 10633, in this Plan. That
section requires that each program is evaluated for several
factors. These factors are included in this section.

Additionally, as a member of the San Diego County Water
Authority, the District benefits from region-wide public
education and information programs. The District also shares in
regional fixture retrofit programs and water use survey programs
for residential and commercial accounts.
A description of the County Water Authority programs, excerpted
from the Authority's 1995 Urban Water Management Plan, is also
included in this section.
PADRE DAM MUNICIPAL WATER DISTRICT CONSERVATION PROGRAMS
The District introduced a water conservation program in 1975,
before the 1976-77 drought. The initial program was primarily
educational, coordinating classroom presentations with the San
Diego County Water Authority, distribution of pamphlets, and bill
stuffers utilizing the District's conservation mascot developed
for the campaign, the Frugal Friar. Since 1990, an itemized
schedule of the costs of water conservation programs is included
in the annual budget as part of the Public Information program.
PAGE 45 Show Image
Examples of several programs are included in the attachments.
During the drought, the efforts were increased with the
distribution of bumper stickers, educational films and a
distribution of water saving kits containing toilet tank
displacement bags and conservation literature.
A second statewide drought, from 1989-1993 included activities in
all areas. With rate increases, mandatory rationing and the
imposition of water use restrictions and penalties; water
conservation activities and customer education programs were
carefully coordinated and implemented to achieve rationing goals
and maintain customer goodwill.
Educational objectives in the District's water conservation
program include, but are not limited to the following:
1) Inform the public that 100% of their potable water is
imported from outside the region. Supplies are dependent on
rainfall in other parts of California and the Colorado River
drainage basin. Water should be considered a valuable
natural resource and should not be wasted.
2) Develop public acceptance of water reclamation as a viable
method of water conservation. Achieve public support for
expansion of the District's reclamation plant and
reclamation projects generally throughout the region.
3) Increase and maintain water-saving behaviors among the
District's customers by offering information on a regular
basis through the customer newsletters, promotional
campaigns and other community activities.
4) Offer programs to customers that provide financial
incentives to conserve or water or offer free assistance on
ways to cut back use in the home and yard.
5) Develop close working relationships with the District's
largest water-using commercial and agricultural customers to
ensure maximum efficiency in water use.
Literature-Brochures BMP 7
The District maintains a literature display in the lobby of the
Administration office. Literature is free to customers who visit

SAN DIEGO COUNTY WATER AUTHORITY
EXCERPTS FROM 1995 URBAN WATER MANAGEMENT PLAN
IMPLEMENTATION OF BEST MANAGEMENT PRACTICES
The Authority assists member agencies in implementing the BMPs in
two ways. As indicated above, the Authority provides direct
funding assistance for the implementation of BMPs. Additionally,
the Authority operates programs to implement BMPs for its
participating member agencies.
The method of implementation for each of the 16 BMPs is discussed
below. Specific levels of implementation for each BMP can be
found in the Authority's annual reports to the California Urban
Water Conservation Council, given in Appendix A.
Water Audits
PAGE 52 Show Image
The Authority, in conjunction with participating member agencies,
operates a program to provide water audit services for single-
family residential, multi-family residential and small commercial
customers. Audits are made available to the tope 30 percent of
users in each category. The survey concentrates on exterior
water use, especially irrigation practices. Additionally,
information and equipment is provided to assist in enhancing in-
door water use efficiency.
Plumbin~
In conjunction with its member agencies, the Authority works to
assure only Ultra-bow-Flush Toilets (UbFTs) are installed in new
construction, and sold or installed in its service area. This
effort has included notices and educational information to local
building departments, workshops for plumbers, and outreach to
plumbing retailers and wholesalers.
The Authority, in conjunction with its member agencies and San
Diego Gas and Electric (SDG&E), distributed or installed over
500,000 conservation retrofit kits for pre-1980 homes. The kits
included: high-quality showerheads, toilet displacement devices,
toilet leak detection tablets and conservation information.
Distribution Svstem Audits, beak Detection, and Repair
Four member agencies participated in an Authority-operated
Distribution System Water Audit. Information derived from the
audit was used by those agencies in determining the need for leak
detection and repair programs in their respective service areas.
Additionally, Authority staff performs annual audits, along with
daily leak detection and repair of its water delivery system.
Metering with Commodity Rates
All Authority water sales are metered. Commodity rates are
included in the Authority's charges to member agencies purchasing
water. Additionally, retail customers in the Authority's service
area are all charged commodity rates for metered water purchased.
bands cape Audits and Incentives
The Authority offers audits of large landscapes at no cost to the
irrigator. The audits are performed by qualified consultants
trained in the Cal Poly method. Follow-ups are performed to
provide additional assistance to irrigators.
Direct financial assistance has been provided to public agencies
who have completed the audit. The assistance has been used to
assure the irrigation system repairs identified in the audit are
implemented. Often, this includes the purchase of matching
irrigation heads or other needed irrigation equipment.
The Authority has sponsored multi-lingual irrigation training
classes. The Spanish language version of the classes, known as
Protector del Agua, was the first in a series of such classes
offered in the Authority's service area. Classes are now offered
in English, as well as Spanish, and at a variety of different
PAGE 53 Show Image
levels of irrigation maintenance skills.
Public Information and Education
These programs educate and inform the public about water either
directly or indirectly through a number of activities. These
include: working with community, political and business leaders
to increase their awareness of Authority programs and the need
for water efficiency, reuse and repurification; good media
relations practices (distribution of press releases, arranging
electronic and print interviews and talk show appearances,
responding promptly to media requests for information), resulting
in water-related news stories and editorials; writing guest
editorials and letters to the editor; public service
announcements for electronic media; print, electronic, outdoor
and multilingual advertising as appropriate; development and
distribution of appropriate literature (bill inserts, brochures,
fact sheets, charts, etc.); speakers' presentations to community
groups; development of audiovisual presentation materials for
speakers; sponsorship of conservation-related
~0~Petitions/awards; presence (through booths, displays) at
community events; and coordinating all such
informational/educational efforts with appropriate gOvernmental
agencies, businesses and community groups.
School Education
The School Education Program focuses on educating young people
about where the region's water comes from and instilling in them
the importance of conservation. An ongoing program for
kindergarten through 12th-grade students consists of development
curriculum, classroom presentations for fourth-graders, secondary
students, and in-service teacher training. Other student-focused
activities include an interactive play about the history of water
in the San Diego area and importance of wise water use, a garden
designed to educate teachers and students about water-efficient
landscaping, a conservation patch program for youth groups, and a
water quality testing program emphasizing hands-on testing of
local waters.
Commercial, Industrial and Institutional
The Authority manages a program that offers audits to the top 10
percent of the commercial, industrial or institutional customers
of its participating member agencies. Through the audits,
participants are encouraged to make cost-effective improvements
to their water use practices.
New Commercial, Industrial and Institutional
Information to encourage water use efficiency in design of new
commercial, industrial and institutional facilities is made
available through the Authority.
Conservation Pricino
The Authority bills its member agencies on a commodity basis for
metered water use. Additionally, retail customers in the
Authority's service area are also billed on a commodity basis for
PAGE 54 Show Image
metered water use.
Residential Landscape Conservation
The Authority, in conjunction with its member agencies, has
offered workshops to alert local land use regulatory agencies of
their responsibilities relative to establishment and enforcement
of landscape water conservation ordinances. Those
responsibilities are detailed in the state Water Conservation in
Landscaping Act. The Authority and its member agencies have
served in an advisory role to assist these regulatory authorities
in designing the ordinances. Finally, the Authority and its
member agencies have assisted in relaying information concerning
the new regulations to the local landscape industry.
Workshops to guide homeowners in design and maintenance of water
efficient residential landscapes have also been sponsored by the
Authority. The workshops were held at the San Diego Zoo and San
Diego Wild Animal Park, and provided specific direction to
homeowners about water efficiency opportunities in their
residential landscape.
Water Waste Prohibition
While the Authority does not have jurisdiction over water waste
prohibition regulations, it has assisted its member agencies in
drafting such prohibitions in the past.
Water Conservation Coordinator
The Authority currently has four staff positions dedicated to
implementing its water conservation programs.
Financial Incentives
The Authority, in conjunction with its member agencies and MWD,
have offered direct financial incentives to participants in the
Showerhead Distribution, Public Facilities Irrigation Assistance,
Public Facilities Plumbing Assistance and ULFT Voucher/Rebate
programs.
Ultra-Low-Flush Toilet Replacement
The Authority, in conjunction with its member agencies and MwD,
has assisted in funding and operating three types of ULFT
replacement programs resulting in the installation of
approximately 200,000 ULFTs:
1. ULFT Voucher/Rebate - Through this program participating
customers have been offered up to a $75 rebate or voucher toward
the purchase of an approved ULFT. The Authority has operated the
program on behalf of its participating member agencies, except in
the city of San Diego, The city of San Diego operates its own
program with financial assistance from the Authority and MWD.
2. Community Based ULFT Distribution - This program offers ULFTs
at no cost to low-income customers for installation in their
homes The Authority operates the program, and community-bases
organizations distribute the ULFTs. The program not only reaches
PAGE 55 Show Image
customers who have traditionally not participated in other
conservation programs, it also but provides employment
opportunities for community residents.
3. Public Institutions Plumbing Retrofit - This program targets
public facilities (i.e. parks, libraries, schools and offices)
for installation of UThFTs and other efficient plumbing devices.
The Authority and MWD fund the purchase cost of the ULFTs, while
the public facility participants are responsible for assuring
installation.
Clothes Washer Rebates
SDG&E operates a clothes washing machine rebate program that is
partially funded by the Authority and MWD. The program offers a

CHAPTER 1 - SECTION 10631 - E2
E2. An estimate of the minimum water supply available to the end
of 12, 24 and 36 months, assuming the worst case water supply
shortages.
Disaster scenario, total supply interruption
The District purchases 100% of its water from the San Diego
County Water Authority which in turn buys it from the
Metropolitan Water District of Southern California. The water is
a blend from the Colorado River and northern California sources.
The District has no reservoirs to collect natural runoff and no
artificially constructed reservoirs to hold imported raw water
supplies. The District operates no wells and has no gr6und water
sources or desalination plants.
A wastewater reclamation plant supplies reclaimed water to a
series of recreational lakes, the Santee IJakes, and irrigates the
surrounding parkland. By 1997, this facility will be producing 2
MGD. After the use taken daily to supply the Santee Thakes, 1 MGD
will be available for irrigation purposes within the City of
Santee. The production of 2 MGD of reclaimed water from this
facility will supply 10% of the District's daily water demand.
In the event that the treated water aqueduct operated by the San
Diego County Water Authority which supplies water to the Padre
Dam Municipal Water District were interrupted, the District would
have to rely on the maximum four day's operational storage in its
tank reservoirs and supplies from an intertie to a neighboring
District.
If supplies provided through the aqueduct operated by the
Metropolitan Water District to the San Diego County Water
Authority were to be interrupted, the scenario for the District
would be the same.
Insufficient regional emergency storage
There is insufficient emergency storage for both the District and
its suppliers. Several member agencies of the San Diego County
Water Authority own and operate their own emergency reservoirs.
On the whole, these reservoirs have direct connections only to
their particular service areas.
In order to address insufficient emergency storage for the SAn
Diego Area, the Metropolitan Water District of Southern
California currently has plans to increase this storage by
constructing the Eastside Reservoir near Hemet, California.
PAGE 88 Show Image
The San Diego County Water Authority is addressing the lack of
regional emergency water storage in the area and is proposing to
construct facilities and systems which would increase the
available water storage in the area by 90,100 acre feet. The
project is in the final environmental review stage (December
1995) -
The District shares an intertie (Connection 6) with a neighboring
provider, the Helix Water District, which owns a 9,000 acre feet
storage reservoir and filtration plant. Through arrangements
with the County Water Authority, the District utilizes this
intertie on a daily basis. For emergencies, this intertie can
supply less than one-half of the District's normal warm season
demand.
Long-term supply shortages, 50% reduction
In the event that the District were to have supplies reduced by
50% for a lengthy duration, compensatory reductions in use would
have to occur. Reductions would need to closely match the level
of supply cutbacks. Therefore, a 50% reduction in supply to the
District would need to be matched by a 40% reduction in use,
accounting for 10% supplied by reclaimed water from the
District's reclamation facility.
Average daily purchases of water through two supply connections;
Padre Dam MWD
Summer average
(July,August,Sept 1995 average)
Connection 4 (direct CWA) 14.34 million gallons per day
Connection 6 (via Helix WD) 10.07 million gallons per day

Win~er average
(Jan, Feb, Mar 1995 average)
Connection 4 (direct CWA) 8.03 million gallons per day
Connection 6 (via Helix WD) .89 million gallons per day
Total 8.92 million gallons per day
The amount of water obtained from connection #6 via Helix Water
District varies according to season. Generally, District
purchases of water are 2/3 from connection #4 and 1/3 from
connection #6.
Typically, the District can receive B million gallons per day
from the Helix Water District connection #6. However, with the
addition of a booster pump utilized in emergencies, 16.8 million
gallons per day are available through that connection. During an
emergency, the Helix Water District would need to carefully
consider the demands of its own customers before making the water
available to other agencies.
PAGE 89 Show Image
The storage tank reservoirs within the District contain
approximately 4 day's average use. With a 50% reduction in
customer demand, this reserve could last for 8-10 days.
The attached chart shows the amount of water estimated to be used
at normal demand projections for three years and the "worst case'
supply projections at a 50% supply shortage.

CHAPTER 1 - SECTION 10631 - E3
E3. Stages of action to be undertaken by the urban water
supplier in reponse to water supply shortages, including up to a
50% reduction in water supply, and an outline of specific water
supply conditions that are applicable to each stage.
The District continually monitors the water supply and demand of
its customers. As all water supplies are purchased from the San
Diego County Water Authority, int~rruptions to Authority supplies
or restricted supplies from the Metropolitan Water District can
cause immediate short or long-term shortages to the District.
Current District Rules and Regulations authorize the General
Manager or designee to take any appropriate actions necessary to
achieve the water conservation goals set for the District in
cases of supply shortages or emergencies. See Ordinance 91-5,
"Water Conservation Plan" in the Appendix.
At the time of preparation of this Plan, revisions to the
District's current Rules and Regulations are being compiled to
address certain actions required by the District during
shortages. In several instances, the need for immediate
restrictions has caused a series of actions by District staff to
immediately curtail unnecessary water use, such as landscape
irrigation. These measures have been imposed in the past at the
discretion of the General Manager.
The revisions to the District's Rules and Regulations will
formalize those policies. It is expected that these revisions
will be considered by the District's Board of Directors in late
1995. See "Staff Recommended Draft - District Rules and
Regulations, Section 5, Water Supply System" in the Appendix.
Depending on the severity and duration, during water supply
shortages, the District may implement certain procedures and
activities listed below:
1) Impose Emergency Water Use restrictions, as required by San
Diego County Water Authority or for District need. (See
Chapter 1, E-4 and explanation below.)
2) Declare and implement actions for the District's Water
Supply Management Condition (See Appendix.)
3) Implement stage of IICP as required by Metropolitan Water
District of Southern California (See explanation below and
Ordinance 91-6 in the Appendix.)
4) Implement District Conservation Rates and Water Use
Allowances for each rate, (See Chapter 2-~ and Ordinances
94-13 and 94-14 in Appendix.)
PAGE 91 Show Image
5) Obtain water supplies, if available, through inter-ties to
neighboring agencies. (See Chapter 2-2.)
6) Assist in implementing Mutual Aid Agreements with
neighboring utilities and other disaster preparedness
agencies. (See explanation below.)
7) Establish actions incorporated in Standardized Emergency
Management Systems (SEMS) as needed. (See explanation
below.)
8) Implement public information campaigns to meet water
restriction goals, including instructions in the appropriate
use of greywater, if permitted by local health officials.
(See Chapter 1-K, Chapter 2-6, and Best Management Practices
Report included with this Plan).
Further details about these items are:
1) San Diego County Water Authority, emergency water use
restrictions
In the event that the District's wholesale water provider,
the San Diego County Water Authority, declares that supplies
to the region are cut back to a 50% level, it may require
member agencies to enact certain water use restrictions to
achieve this level of reduction. These restrictions should
be similar to those set out in the Authority's Ordinance 91-
6. Districts may also be subject to various penalties
levied by the Authority and/or the Metropolitan Water
District for not achieving these percentage reductions.
The San Diego County Water Authority's Ordinance No. 91-6,
adopted June 25, 1991, that in the event of an emergency or
long-term supply reduction, Establishes rules, regulations,
and restrictions so that available water supplies are
allocated among member agencies for the greatest public
interest and benefit. Included in this ordinance is a list
of water use restrictions to be used by retailers within its
service area if the retailer does not have in place similar
use restrictions. See Ord. 91-6, CWA Restrictions on Water
Supplies in the Appendix.
3) Metropolitan Water District of Southern California
Incremental interruption and conservation program'
The level of conservation required for the region is set by
the Authority's supplier, the Metropolitan Water District,
who has established an Incremental Interruption and
Conservation Program (IICP) which was adopted on December
11, 1990 as a means of allocating water to its member
agencies during drought conditions. The Authority is obliged
to comply with reductions and restrictions enacted by the
PAGE 92 Show Image
Metropolitan Water District and to pass them on to its
member agencies, which includes the Padre Dam Municipal
Water District.
On January 22, 1991, the Padre Dam Municipal Water District
adopted Resolution 91-8 authorizing implementation of the
IICP to its retail districts and passing on any water use
and supply restrictions and financial incentives and
disincentives to those districts (See Resolution 91-8
attached.)
6) Mutual Aid Agreements
The District has entered into mutual aid agreements with
several neighboring utilities and other local public health
and safety agencies to provide voluntary sharing of
materials, equipment and personnel among the contracting
parties, based upon need. The District also participates in
a mutual aid agreement with the Metropolitan Water District
Cooperative Systems plan.
7) Standardized Emergency Management Systems
The District has re-written all emergency preparedness and
response documents to comply with the state mandated
Standardized Emergency Management Systems (SEMS) as required
by SB 1841. The new document will be adopted by the
District's Board of Directors by Resolution in December 1995
to comply with required adoption date of January 1, 1996.
The SEMS document simplifies and provides standardized
emergency response procedures for all districts, police,
fire and other public health and safety authorities with the
state.
There are four basic parameters in the SEMS procedures. An
incident manager must be declared who then delegates
activities in the areas of operations, planning assessment,
logistic resources and administration. Since all utilities
and response authorities will utilize the same structure
during an emergency, the SEMS approach allows personnel to
be utilized at other agencies with a mimimun of orientation
and effort.
In addition to adopting the SEMS plan, the District
participates in a Multi-Agency Coordination System and a
Multi-Agency Radio System (MARS).

RESOLUTION OF THE BOARD OF DIRECTORS OF
PADRE DAM MUNICIPAL WATER DISTRICT
PROVIDING FOR THE IMPLEMENTATION OF
THE METROPOLITAN WATER DISTRICT
OF SOUTHERN CALIFORL~IA
INCREMENTAL INTERRUPTION AND CONSERVATION PLAN
WHEREAS, four consecutive years of drought conditions
throughout the State of California and the Colorado River Basin
have created an unprecedented threat to the sufficiency of the
imported water supply of the San Diego County Water Authority
and Padre Dam Municipal Water District; and
WHEREAS, the Metropolitan Water District of Southern
California has evaluated the groundwater and surface storage

CHAPTER 1 - SECTION 10631 - E4
E4. Mandatory provisions to reduce water use that include
prohibitions against specific wasteful practices, such as gutter
flooding.
The District has adopted Ordinance 91-5 Water Conservation Plan
which contains water use restrictions for its customers. This
current Ordinance is the third revision to the District's Water
Conservation Plan and is the result of two years' experience with
both voluntary and mandatory water rationing. Certain water use
restrictions have been modified as a result of customer use
habits and enforcement experience. The current version contains
financial penalties for violating any of the provisions of the
ordinance.
The plan is divided into two sections Part I and Part II. Part I,
entitled UNORMATh AND WATER SHORTAGE CONDITIONS, contains water
use restrictions and enforcement measures to be in effect at all
times, including times of water supply shortages.
Part II, entitled WATER SHORTAGE EMERGENCY CONDITIONS, contains
additional measures and strengthens the restrictions in Part I.
Stronger enforcement measures are added. The restrictions in Part
II are to be used in times of severe cutbacks from the District's
water supplier, or in times of a temporary disruption of supply,
storage, distribution or other facilities.
The current version of Part I was developed in collaboration with
five other neighboring water districts. It was felt, after
several months' experience with mandatory rationing, that
customers would be more cooperative if the restrictions were
consistent with those of their neighbors. In addition, joint
public education between the agencies would be more effective and
during times of drought restrictions, joint publicity would be
cost-effective.
None of the districts involved in this collaborative process had
service area boundaries that coincided exactly with any city
limits. For example, one municipality is served by three water
districts. Certain neighborhoods had water served by one
provider while on an adjacent street, residents were served by
another. Additionally, these Districts were in the same climatic
zone, with consistent weather patterns and watering reouirements
for landscape.
The collaborative process was especially beneficial in
determining water use restrictions on outdoor landscaping.
Consistent restrictions also facilitated cost-sharing of
newspaper advertising (See Ordinance 91-5 in the Appendix).
PAGE 96 Show Image
CHAPTER 1 - SECTION 10631 - E5
E5. Consumption limits in the most restrictive stages. Each
urban water supplier may use any type of consumption limit in its
water shortage contingency plan that would reduce water use and
is appropriate for its area. Examples of consumption limits that
may be used include, but are not limited to, percentage
reductions in water allotments, per capita allocations, an
increasing block rate schedule for high usage of water with
incentive for conservation, or restrictions on specific uses.
On February 26, 1991, the District established an inclining block
rate structure with use allowances within each block to encourage
decreased water use during times of supply shortages. Within
this structure is the flexibility to alter use allowances within
each block. The use allowances are decreased by the same
percentage reduction that is being required of the District as a
whole. The base is determined by the average use for customer
type.
The District does not use historical comparisons for use
reductions and does not use a per capita allocation for billing
determinations. The block rate structure has been successful in
reducing customer demands to the level required by the District's
supplier. See Ordinances 94-13 and 94-15, Water Commodity Rates'
and Ordinance 94-15 `Water Use Allowances" in the Appendix.
PAGE 97 Show Image
CHAPTER 1 - SECTION 10631 - EG
EG. Penalties or charges for excessive use.
The District's inclining block rate structure contains three
prices for water used in different quantities. The highest rate
is priced to discourage water used in quantities subject that
rate.
The District does not have penalties or charges for excess use.
The billing structure does not use a per capita or household
allocation system. See Ordinance 94-13 and 94-14 Water
Commodity Rates~ and Ordinance 94-15 Water Use Allowances' in
the Appendix.
PAGE 98 Show Image
CHAPTER 1 - SECTION 10631 - E7
E7. An analysis of the impacts of the plan on revenues and
expenditures of the urban water supplier, and proposed measures
to overcome those impacts, such as the development of reserves
and rate adjustments.
The District adopted a tong Range Financial Plan in (Ordinance
94-12) on January 19, 1995 which forinalized language for
established general funds, restricted cash funds, and trust
funds. Included in the restricted cash funds is a rate
stabilization fund.
Conservation education and enforcement efforts to achieve a 50%
decrease in water use over a 12-36 month period, would require
additional expenditures. The extent of these added costs will
vary, depending on the severity and duration of the supply
reduction and the degree of customer compliance.
In 1991, the District adopted an inclining block rate structure
that can be used to increase the price of water at various use
levels. This rate structure can be adjusted to be responsive to
certain supply conditions.
Once the District's water reclamation facility 2MGD upgrade
project is fully operational, approximately 10% of the District's
daily water demand can be supplied by reclaimed water from the
facility.
The calculations below indicate the estimated loss of revenue
from the sale of water to customers during a 36-month cutback of
50% in water supplies. At the end of a 36-month cutback, total
losses in revenue to the District are estimated at $4,103,252.
At the time of this writing, there are sufficient funds in the
Rate Stabilization designated fund to maintain operational
expenses over a 36 month period of time.

CHAPTER 1 - SECTION 10631 - E9
E9. A mechanisin for determining actual reductions in water use
pursuant to the urban water shortage contingency plan.
The District receives all of its potable water through two
metered connections. During times of water shortages, these
meters are read daily. The District's distribution system allows
for reading meters at all turn-outs in the retail system. Three
wholesale terminal reservoirs are used for distribution to
portions of the District's retail service area and to the
Lakeside Water District and Riverview Water District.
The District utilizes a telemetry system to monitor all water
flows and levels in the District's 26 storage reservoirs. During
emergency periods with water cutback goals of 50% reduction,
water flows into the District were measured daily and determined
that use was down to 50%, and exceeded that on some days, during
the emergency.

F. Describe the frequency and magnitude of supply deficiencies,
based on available historic data and future projected conditions
compar~ng water supply and demand, including a description of
deficiencies in time of drought and emergency and the ability to
meet deficiencies.
The District imports 100% of its water from the San Diego County
Water Authority who purchases this water from the Metropolitan
Water District of Southern California. In April 1989, the
District declared a Stage 2 Water Alert at the request of the
Authority. This marked the first time that the District had
required mandatory conservation from its customers in the history
of the District. A chronology of drought/conservation response
is attached.
The District's water reclamation facility 2 MGD upgrade will be
able to produce 10% of the District's normal daily water demand.
During an emergency, this would help to offset the need for
imported water.
Included below is a description of the Metropolitan Water
District's Incremental Interruption and Conservation Plan (IICP)
and its relations to water supplies for the San Diego County
Water Authority. The material is taken from the Authority's
Draft Urban Water Management Plan 1995 Update with permission.
SAN DIEGO COUNTY WATER AUTHORITY, DRAFT URBAN WATER MANAGEMENT
PLAN 1995 UPDATE, SECTION 7, DROUGHT MANAGEMENT
In the recent past, the Authority has largely shared the water
shortages of its sole supplier, the Metropolitan Water District
(MWD) . Because an average of 90 percent of the water used in the
San Diego region is imported from MWD, shortages that are imposed
by the MWD tend to be translated to equivalent shortages by the
Authority.
Drought shortages during 1991-92 were ameliorated, however, by
the Authority's ability to purchase transfer supplies from a
newly established state water bank, and by using water stored in
local surface reservoirs. Each of these measures lessened the
conservation requirement of Authority member agencies by about
five percent. Whereas MWD required a reduction of 31 percent of
base-year (1989-90) deliveries, the Authority requested its
member agencies to reduce deliveries by 20 percent during that
year. Transfers are expected to play an even larger role in
lessening future water shortages.
Recent Drou~ht Mana~ement Programs The six-year drought that
ended in 1992 resulted in a number of regional programs designed
to fairly and efficiently deliver water during times of shortage.
Major drought management plans began in 1988, when MWD prepared a
PAGE 107 Show Image
Drought Action Plan to reduce regional water demands. The Plan
included the optimization of supplies from the State Water
Project and the Colorado River Aqueduct, and a number of demand
management techniques, including voluntary 10 percent
conservation. In 1989, an Authority committee developed a model
water supply emergency ordinance that specified appropriate
responses to various levels of supply. The ordinance was also
used for drafting individual member agency ordinances.
MWD adopted a revised Drought Action Plan in 1990 that
intensified both supply and demand management. While maintaining
its 10 percent voluntary conservation goal, MWD instituted a
conservation incentive program that paid $100 per acre-foot to
any member agency that reduced demand to less than 95 percent of
what was used during the same period in 1989. Also beginning in
1990, Authority water deliveries from MWD began to be reduced
under an MWD program called the Incremental Interruption and
Conservation Plan (IICP).
The IICP had several stages of delivery reductions, which were
determined largely by the availability of imported supplies from
the State Water Project and local supplies from MWD's member
agencies. The program had six stages of delivery reduction
targets, ranging from Stage 1, voluntary conservation of 10
percent, to State 6, which reduced non-f irm deliveries by 30
percent. The percentage reductions used in each stage were based
on deliveries made in 1989-90, adjusted for growth, loss of local
supplies, conservation, and reclamation. The IICP featured
financial penalties, or disincentives, for agencies that failed
to reduce deliveries to the appropriate level. For a brief time,
MWD also offered financial incentives to those agencies that
conserved in excess of the stage target. A chronology of the
IICP and delivery reduction targets is given in Table 7-1.
MWD and 11 other urban and agricultural water districts
participated in a State Drought Bmergency Water Bank, beginning
in 1991. The water for the bank was obtained by following or
idling farmland in northern California, using groundwater instead
of surface water, and transferring surplus surface waters from
local reservoirs to the bank. During the 1991-92 fiscal year,
the Authority purchased more than 21,000 acre-feet from this
bank. This water was critical to alleviating the severity of the
local drought shortage.
Authority requests for conservation from its member agencies
essentially mirrored each IICP stage. In December 1990 MWD
initiated IICP Stage 1 and the Authority requested its member
agencies to reduce overall water consumption by 10 percent; in
February 1991 MWD went to Stage 3, and the Authority requested 15
percent conservation; in March 1991 MWD went to Stage 5 and the
Authority requested 31 percent conservation. Later the Authority
purchased state water bank supplies and used local water to
reduce its conservation target to 20 percent. This lasted until
heavy rainfall restored supplies for the entire state in March
PAGE 108 Show Image
1992.
To achieve the conservation targets through this period of
drought, the Authority and its member agencies launched
aggressive short-and long-term water conservation campaigns.
In March 1991, the Authority enacted Ordinance 91-1, "Declaring
the Existence of a Water Shortage Emergency Condition and
Establishing Procedures to Preserve and Allocate Available Water
Supplies." This ordinance provided direction for securing and
managing water supplies during times of drought, making delivery
allocations to member agencies, conservation programs to achieve
water savings, and financial surcharges for exceeding
allocations -
Current MWD Drou~ht Management In response to the dry winter of
1994-95, MWD established the 1995 Drought Management Plan. This
plan, which was designed as a set of operating procedures for
calendar year 1995, sought to minimize impacts to the retail
customer. The principles of this plan, which are also supported
by the Authority, are given by MWD as follows:
Avoid mandatory stages of IICP to the extent practicable.
Use water management programs in a coordinated and efficient
manner.
· Operate MWD's system to capture and store excess water in
groundwater and surface storage.
· Encourage regional storage during periods of excess supply
and encourage use of this storage during periods of drought.
· Use equitable means to conserve and use alternative
supplies.
Adopt measures that will balance costs and inconvenience to
customers.
· Avoid financial hardship to MWD and its member agencies.
Use cost-effective transfer programs.
· Use public information to encourage efficient water use, and
to educate the public on water supply and reliability
issues.
· Recognize the need to minimize the impacts of water shortage
on the region's economy.
· Reward conservation efforts through water allocation
methodology and penalize inefficient water practices.
MWD modified its IICP program for 1995, and planned to use
implementation of this program only as a final resort during a
water shortage. Notable changes to the program included the use
of a three-year average base period (currently 1989-92), revised
conservation stages, and a target marketing system for marketing
unused allocations between MWD member agencies. Current IICP
stages, percentage reductions, and disincentives for use over
target levels are given in Table 7-2. The overall reduction is
for all MWD member agencies as a whole, not for the Authority.
Current Authority Drought Management Since 1991, the Authority's
PAGE 109 Show Image
Ordinance 91-1 has been through a number of revisions and
amendments. The latest version is Ordinance 94-3, "Ordinance of
the San Diego County Water Authority Establishing Contingency
Plans, Rules, Regulations, and Restrictions, so That Available
Water Supplies are Allocated Among Member Agencies for the
Greatest Public Interest and Benefit." A copy of this ordinance,
which was adopted by the Authority board in December 1994, is
included in this (the Authority's) Plan as Appendix B. A table
of water conservation measures that are recommended by this
ordinance to achieve water savings is also included in Appendix B
(Authority's Plan). This table provides a number of conservation
scenarios, including short-term water system failures, in which
no water would be delivered by the Authority. This situation
could exist if the region were subjected to an earthquake that
severed Authority or MWD pipelines.
Ordinance 94-3 uses the following principles to secure and manage
water supplies during a drought:
Minimize shortages by using Authority-owned storage and
securing additional supplies.
· Increase deliveries from MWD through target marketing
provisions of the IICP.
Negotiate with member agencies for the use of locally stored
water.
Allocate available MWD supplies using IICP methodology and
reduction percentages for firm and agricultural supplies.
Recommended conservation programs and techniques to member
agencies.
- Monitor member agencies deliveries and use.
· Share MwD disincentive surcharges for using excess water.
The Authority is somewhat limited in the range of supply options
that are available to cope with drought shortages. Currently,
the Authority neither owns nor operates any surface reservoir or
groundwater facilities, reclamation plants, or desalination
plants. To supplement normal deliveries from MWD, the Authority
may use water it stores locally (up to 40,000 acre-feet),
purchase supplies from the state water bank, increase its MWD
allocation through MWD's target marketing system, or purchase
water transfers independently of MWD. The Authority is also
reviewing opportunities to store water in the groundwater basins
of other MWD member agencies, a supply that would be used only in
times of drought.
Revenue Im~acts of Drought The Authority receives 53 percent of
its revenue from water sales. If these revenues are less than
required to meet the Authority's financial obligations, a rate
stabilization fund is utilized. If these monies are not
sufficient, revenue enhancement options would be reviewed and
appropriate responses implemented.
In the event of a water emergency, an ordinance similar to
Ordinance 94-3 would be activated to respond to the level of
PAGE 110 Show Image
shortage. At that time drought response stage actions would go
into effect, and the Authority would be operating with reduced
water sales. The amount of decreased revenue would depend upon
the response stage under which the Authority would operate.

CHAPTER 1 - SECTION 10631 - G
G. To the extent feasible, describe the method which will be
used to evaluate the effectiveness of each conservation measure
implemented under the plan.
The District uses several methods of evaluating the effectiveness
of conservation measures. Programs which are implemented by
consultants whose services are shared by the District and it's
wholesaler, the San Diego County Water Authority, are primarily
measured by utilization. Fixture replacement and retrofit
programs allow for fixed amounts of water savings to be
calculated per retrofit.
Other conservation programs such as landscape water audits are
more difficult to quantify water savings. Factors such as
weather patterns and changes in ownership can affect water use
and conflict with yearly comparisons of water saved.
Utilization of programs, requests for educational materials,
responses to items in District printed materials, questions at
speaking engagements and community events provide informal
tracking of interest and utilization of conservation programs.

Practices Retail Water Agency Annual Report" in the Appendix.

CHAPTER 1 - 10631 - H
H. Describe the steps which would be necessary to linpiement any
proposed actions in the plan.
Each fiscal year, District staff develops a Public Relations
Annual Plan which is adopted by the Board of Directors. The Plan
includes a description of various public information, customer
education and community relations programs planned for the
District for the following fiscal year. A section on
Conservation Programs is developed and included in detail.
A Conservation budget is prepared by staff for each fiscal year
and included with the operating budget. As the District is a
signatory to the Memorandum of Understanding Regarding Urban
Water Conservation in California, the District is obliged to
implement, where feasible, 16 Best Management Practices. These
practices are designed to achieve permanent water savings, either
through plumbing retrofits, behavioral change in water use
practices or other measures. Several of the 16 Best Management
Practices are for internal agency use to monitor water use,
implement rate structures, etc.
A member of the District staff is assigned responsibility to
design and implement the District's conservation programs.
PAGE 114 Show Image
CHAPTER 1 - SECTION 10631 - 1, 1-4
I. Describe findings, actions, and planning relating to all of
the following:
1. The use 0£ internal and external water audits for single-
family residential, multifamily residential, institutional,
commercial, industrial, and governmental customers, and the use
of incentive programs to encourage customer audits and program
participation.
2. The use of distribution system water audits.
3. Leak detection and repair.
4. The use of large landscape water audits.
The above listed items are included in the W?California Urban
Water Conservation Council Best Management Practices Retail Water
Agency Annual Report.
District customers have continually been faced with increasing
water rates over the past several years. Participation has been
excellent in programs that offer incentives to replace high water
use plumbing fixtures, ULFT rebate and voucher programs, free
showerhead replacements, etc.
Due to the demographics of the service area, it is more difficult
to achieve complete utilization of home water audits. The
majority of the lot sizes in the service area tend to be small-
average, making for less opportunity for water savings outdoors.
Other portions of the service area which do have large
landscapes, may not have someone at home during the day to take
advantage of the audit opportunities.
The District does not offer financial incentives on the bills for
decreased water use.
PAGE 115 Show Image
CHAPTER 1 - SECTION 10631 - j
J. Describe actions and planning to eliminate the use of once-
through cooling systems, non-recirculating water systems, and
non-recycling decorative water fountains, and to encourage the
recirculation of water if proper public health and safety
standards are maintained.
The District's Engineering department reviews all applications
for new water service in the District. All applicants for new
service are carefully reviewed to determine the prospective water
uses at the property. The District does not have any ordinances
against non-recirculating water systems.
Due to the very light industrial activities within the District's
service area, there are no large industries that require cooling
towers. Since all of the District's water supply is imported,
car washes and similar operations in the area would find it
economically prohibitive if the water was not recycled in the
operations.
There are several light industries that use substantial amounts
of water for cooling. The District's industrial waste ordinance
permits frequent inspections of the facility. This affords the
opportunity for District employees to review water use as well as
wastewater discharge complianc~. At these opportunities, any
water-conserving procedures can be recommended.
All outdoor decorative fountains in the District's service area
have been recently constructed and, as with car washes, would
find it economically prohibitive to not recirculate water in the
fixture.
PAGE 116 Show Image
CHAPTER 1 - SECTION 10631 - K
K. Describe actions and plans to enforce conservation measures.
The District uses a variety of methods to educate customers on
the current conservation measures. Some of these are articles
printed in the District's customer newsletter, notices printed on
bills, and display advertisements in the local newspaper. The
District has a water conservation mascot, the Frugal Friar, which
is used in publications to provide reminders of water
conservation measures and wise water use methods.
Enforcement of water conservation measures is included in the
District's Water Conservation Plan (Ordinance 91-5). During
recent mandatory water use restrictions, customers were self-
policing and reporting visible violations of the water use
restrictions. The District was not able to provide employees to
be solely on patrol looking for violations, but when reported
violations were called in to the District office, crews were
dispatched via mobile radio by the customer service department to
the site in ouestion.
If an employee noted the violation, procedures were begun to
notify the customer by mail. A second offense noted by an
employee generates a fine. See Ordinance 91-5 "Water
Conservation Plan" in the Appendix.

through water conservation measured employed by user groups.
As part of a 1993 update to a District Residential Classification
Study comparing water use and lot size, an average bimonthly
water consumption per household was determined over a several

of mandatory rationing required by its wholesaler. A portion of
this 1993 study is attached.

CHAPTER 1 - SECTION 10631 - N
M. Describe actions and planning to ensure the involvement of
community members within the service area with regard to water
management planning -
The District purchases 100% of its potable water from the San
Diego County Water Authority, which has the responsibility for
distribution of water to its member agencies. Over 90% of these
deliveries are purchased from the Metropolitan Water District of
Southern California. Regional water management planning for
additional supplies and storage are components of the long range
regional planning of these two wholesale agency.
Two key projects recently of these two agencies have involved
extensive community involvement - the Eastside Reservoir of the
Metropolitan Water District and the Emergency Storage Project of
the San Diego County Water Authority. Both of these projects are
designed to provide additional water storage for the area in case
of emergencies or long-term restricted supplies to the area.
The District has a variety of ways that the community
participates in water management planning, particularly in the
area of developing additional recycled water.
Community meetings have been held to provide information and hear
comments on District planned increases in the production of
reclaimed water. Environmental documents have been widely
distributed for public comment. Public hearings have been held
to receive formal public comment. Participation in community
events, a speaker's bureau and open house informational meetings
have provided opportunities for informal public comment.
Additional storage facilities (tanks) have been constructed by
the District in the service area in recent years. The three
constructed most recently involved an extensive community
relations program, allowing the public an opportunity to receive
detailed information on the need for these projects. Each
written communication provided a District staff name and phone
number for questions and comments.
The adoption of a Water Master Plan, Wastewater Master Plan and
Water Reclamation Master Plan in recent years provided
opportunities for community groups and interested parties to
provide comment.

CHAPTER 2 - SECTION 10632 - (a), (b)
(a) In addition to the eleinents required pursuant to Section
10631, a plan projecting a future use which indicates a need for
expanded or additional water supplies shall be adopted in
accordance with this chapter and shall include an evaluation of
the following alternatives. (Refer to the following sub-sections
1 through 7.)
(b) The preparation of the plan shall be coordinated with local
water, waste water, and planning agencies.
The Padre Dam Municipal Water District is both a wholesaler and
retailer of potable water. In addition, the District produces
and distributes reclaimed water. Approximately 80% of the
wastewater collected in the District's collection system is
discharged into the San Diego Metropolitan Sewerage System where
it is processed at a regional wastewater treatment facility with
an ocean outfall.
tJocated completely within the District's service area is the
incorporated city of Santee and portions of another city, El
Cajon. Other unincorporated coinmunities within the District's
service area are subject to the governance of the County of San
Diego.
The District works closely with all of these communities
including several fire protection districts, sanitation
districts, and planning agencies to developing and implementing
areas of this Plan. The development of additional recycled water
sources is coordinated with the San Diego County Water Authority.

In 1990, the District commissioned engineering consultants, Dudek
and Associates to develop a Water Reclamation Master Plan. The
Plan was adopted by the District's Board of Directors on January
22, 1991, Resolution 91-7. See attached.
Included in this subsection is material taken from the Water
Reclamation Master Plan which provides a detailed description of
the wastewater collection and treatment systems in the service
area, a quantification of the amount of wastewater collected and
treated, and the methods of wastewater disposal. See attached
Chapters 1, 2, 3 from the "Water Reclamation Master Plan.
Also included as a description of the recycled water currently
being used in the District's service area are two fact sheets and
several pages from the Padre Dam Water Reclamation Project Final
Subsequent Environmental Impact Report, prepared in February 1995
by Brian F. Mooney Associates and adopted by the District's Board
of Directors on February 22, 1995. See attached `Padre Dam Water
Reclamation Project Fact Sheet, District Fact Sheet, `I and
"Reclamation Project Final Subsequent EIR."
At the completion of upgraded facilities at the District's Santee
Water Reclamation Plant, the production of reclaimed water will
increase to 2 MGD. This will supply approximately 10% of the
daily water demands in the District.

CHAPTER 1
SUMMARY
1.1 INTRODUCTION
The preparation of this study was authorized by the Padre Dam Municipal Water District
(PDMWD) in the form of a contract titled "AGREEMENT FOR PROFESSIONAL
ENGINEERING SERVICES BETWEEN PADRE DAM MUNICIPAL WATER DISTRICT
AND LUKE-DUDEK CIVIL ENGINEERS, INC.1 and dated March28, 1990.
The purpose of the Water Reclamation Master Plan (Master Plan) is to define,
encourage, and develop the use of reclaimed water within the PDMWD boundaries. The
Master Plan provides guidance for the planning, scheduling, budgeting, and
construction of a water reclamation system in the PDMWD.
1.2 DESCRIPTION OF STUDY AREA
The study area is defined by the Padre Dam Municipal Water District (PDMWD) water
service boundary and is shown on Figure 1-1. The 85 square miles of the PDMWD are
comprised of the City of Santee, a portion of the City of El Cajon, and the unincorporated
communities of Lakeside, Flinn Spring, Harbison Canyon, Blossom Valley, Alpine,
Dehesa, and part of the Crest area.
1.2.1Land Use
Residential uses in Santee are primarily composed of single family detached units with
some multi-family developments. Commercial development in Santee occupies 181
acres with the majority devoted to retail uses.
Only a small portion of the City of El Cajon is included in the study area, which includes
primarily the Gillespie Field area. The land use designations include both industrial park
and general industrial uses.
The Lakeside Community Plan reports that most of the Current Urban Development Area
in Lakeside is planned for residential use. Agricultural uses have given way to residential
development, but a considerable amount of small scale farming still exists. Crest and
Harbison Canyon are both communities which retain fairly high residential densities
surrounded by areas of lower density estate development and large areas of
undeveloped land.

Existing development in Alpine has a rural character typified by light agricultural activities
practiced in conjunction with residential uses.
1.2.2Water Supply
The PDMWD began in 1977 as the result of the merger of the Santee County Water
District and the Rio San Diego Municipal Water District. As a water agency, PDMWD
sells water on a wholesale and retail basis. The PDMWD serves approximately 17,780
water customers. The current average water demand for PDMWD is about 16 MGD with
a peak day demand of 25 million gallons per day (MGD).
The wholesale water supply system is Improvement District C. Improvement District C
wholesales water to two other improvement districts, Improvement District No. 1 and
Improvement District A, which are operated by PDMWD as retail water service areas,
and to the Lakeside Water District and the Riverview Water District.
1.2.3Wastewater Agencies
PDMWD functions as both a water and sewer agency. The PDMWD sewage operations
serve only the City of Santee Corporate limits and a small portion of the community of
Lakeside and the Pepper Drive area within the County of San Diego. The community of
Winter Gardens and parts of Alpine and Lakeside are served by individual sanitation
districts operated by the County of San Diego. The City of El Cajon operates and
maintains sewage collection facilities within its incorporated areas.
1.3 LOCAL WATER RECLAMATION PLANNING
1.3.1San Diego Clean Water Program Planning
In 1981, the EPA tentatively approved the waiver for secondary treatment for the City of
San Diego, but reversed its tentative approval of the waiver. In 1987, the City of San
Diego decided to discontinue waiver efforts, and has proceeded to implement a
secondary treatment program while concurrently planning to maximize water
reclamation in the Metropolitan Sewage System (METRO) service area.
The Clean Water Program (CWP) for Greater San Diego was created to meet San
Diego's commitment to provide secondary treatment and water reclamation. The CWP
proposes a 24 MGD water reclamation plant for the Santee region by the year 2010.
1.3.2San Diego River Basin Reclaimed Water Planning Study
The recommended water reclamation of the project San Diego River Basin Reclaimed
Water Planning and Development Study (SDRB Study) combines the recommended
wastewater treatment alternative for the Santee Water Reclamation Facility (WRF) and
the recommended reclaimed water distribution facility alternative into an overall project.
1-3
PAGE 128 Show Image
Phase I of the study includes an initial 14 MGD nutrient removal plant with stream
discharge that is ultimately expandable to 34 MGD. Uve-stream conveyance is used to
deliver reclaimed water to downstream users and pipelines are used to serve upstream
users.
1.3.3Basin Plan Amendments
Since the implementation of the Basin Plan in 1976, three changes of Basin Plan water
quality objectives for the San Diego Hydrographic Unit have been approved to relax the
ground water quality objectives to promote the use of reclaimed water in the region.
In April 1990, the Regional Board adopted Resolution No. 90-26 which modified Chapter
5, Implementation Plan of the Basin Plan. The recently adopted Resolution No. 90-40
revises Resolution 90-26 by adding additional language that narrows the setting of
effluent limitations for reclaimed wastewater constituents to a range no higher than the
Basin Plan groundwater objectives, and no lower than an increment above the Basin
water supply.
1.4 RECLAIMED WATER POUClES, REGULATIONS, AND REOUIREMENTS
1.4.1Regulatory Requirements
In California, the policy on the use of reclaimed water is in Sections 13650 and 13551,
Article 7, of the California Water Code, titled "Waste Water Use".
The State Department of Health Services (DHS) has established quality, treatment,
reliability, and operational standards for the reuse of reclaimed water, which are
contained in Title 22, Division 4 of the California Administrative Code (Title 22).
The DHS requires that an engineering report be prepared containing a detailed design of
the proposed reclamation system. In addition to the detailed engineering report, a
contingency plan will be required to assure that no untreated or partially treated
wastewater is used. Guidelines in Title 22 also describe the operational procedures to
be implemented at the reclamation facilities.
The Regional Water Quality Control Board (Regional Board) issues State Waste
Discharge Requirements to agencies producing reclaimed water, and discharging
treated wastewater to land. The Regional Board issues federal National Pollutant
Discharge Elimination System (NPDES) permits to agencies discharging treated
wastewater to navigable waters of the U.S.
To the users and purveyors of reclaimed water, the Regional Board issues a separate
permit termed Water Reclamation Requirements, which describe the criteria and
restrictions required for the safe use of the reclaimed water.

PAGE 129 Show Image
1.4.2Irrigation Water Quality Criteria
Reclamation of wastewater for irrigation must include a comparison of the quality of
reclaimed water with standards applicable to irrigation use.
Salinity, measured in total dissolved solids (TDS), is one of the most important water
quality parameters in determining the suitability of reclaimed water for irrigation. When
reclaimed water is used for irrigation, salts may accumulate in the soil.
Toxicity due to a specific ions occurs when that ion is absorbed by the plant and
accumulates in the plant in amounts that result in damage. Sodium, chloride, nitrogen
and boron in high concentrations are of particular concern in irrigation because of their
potentially toxic effects on some plants.
The forms of nitrogen found in wastewater, largely ammonium with some nitrate, behave
in the same manner as applied fertilizer nitrogen. Excessive nitrogen levels may cause
problems in some sensitive plants by stimulating vegetative growth instead of flowering
and fruiting.
1.5 WASTEWATER FACILITIES AND FLOW CHARACTERISTICS
1.5.1Santee Water Reclamation Facility
Operated since January of 1968, the existing Santee WRF, which is now owned by
PDMWD, is located in the western portion of the City of Santee in Sycamore Canyon.
The PDMWD has completed the planning, environmental review process, and
preliminary design work for an expansion of the Santee WRF to 4.0 MGD. Along with
plant expansion, the PDMWD is proposing modifications to the Regional Board's Basin
Plan and its NPDES permit. These revisions would allow a year round discharge of up to
4.0 MGD of reclaimed water through Santee Lakes into Sycamore Creek and the San
Diego River.
1.5.2Wastewater Tributary Basins, Flows, and Quality
The PDMWD wastewater facilities serve an area of about 13,000 acres that are located
almost entirely within the City of Santee, but also extend into a small section of San
Diego County. The wastewater conveyance system consists of about 139 miles of
sewer, trunk sewer and force mains, and four pump stations.
The existing flows from the nine drainage basins within the PDI\4WlD service area
currently average 4.87 MGD, with a peak hourly flow of 9.24 MGD. Ultimate flows for the
PDMWD wastewater conveyance system are projected to be about 12 MGD by the year
2035 with a corresponding peak flow of 22 MGD.
PAGE 130 Show Image
The San Diego County Water Authority (SDCWA) has developed criteria for wastewater
quality to ensure the suitability of wastewater for reclamation samples of wastewater at
various locations within the study area have been analyzed by the Industrial Waste
Control Division of the City of San Diego's Water Utilities Department. The samples
exhibit acceptable wastewater quality based on TDS levels.
The SDCWA has also developed criteria for wastewater quality control in areas tributary
to reclamation facilities. These tributary protection measures include monitoring, inflow
and infiltration protection, industrial waste regulation, and regulation of self-regenerating
water softeners. The PDMWD currently has a general ordinance for tributary protection
measures that restricts or prohibits waste discharges to the wastewater system upon a
finding by a noticed public hearing that the discharge is harmful to wastewater treatment
and reclamation facilities or reclaimed water users.
1.6 RECLAIMED WATER MARKETS
In the study the term "reclaimed water market" is used to identify a location where
reclaimed water could be used to replace the use or future use of potable water. The
reclaimed water markets were divided into five main categories: irrigation uses, industrial
uses, commercial building uses, recreational uses, and ecological enhancement.
Irrigation uses of reclaimed water may include the irrigation of pastures, crops,
nurseries, golf courses, cemeteries, parks, campuses, and residential, commercial and
freeway landscaping. Irrigation water demands are non uniform, varying seasonally from
the effects of wet and dry weather periods.
The amount of water required for irrigation is dependent on the type of vegetation, soil
type and condition, hours of daylight, temperature, topographic and geologic conditions,
and the method of irrigation water application. In the report, an average applied water
irrigation demand of 30 inches per year [2.5 acre feet/year (AF/YR)j was used for
landscape irrigation markets, unless specific data was available.
Three areas of agricultural production are included as potential markets for reclaimed
water use: the 560 acre avocado grove of Rios Canyon Ranch, 28 acres of avocado
production along La Cresta Road, and the approximate 600 acres of land designated as
agriculture preserve located in the Lakeside Community Plan.
The Carlton Oaks and Willowbrook Country Clubs maintain two golf courses, and three
additional golf courses in the planning stages were identified. Golf courses are planned
for the Fanita Ranch, Alpine, and High Meadow Ranch developments. The Fanita Ranch
Golf Course will be about 175 acres; however, since it is likely that much of the golf
course will remain in a natural state with no irrigation and since no details are available, it
was assumed that 60 percent of the 175 acres will be irrigated. An 80 to 90 acre golf
course is planned for the High Meadow Ranch development.
PAGE 131 Show Image
Water use by the California Department of Transportation (CALTRANS) for irrigation of
landscape along freeways within San Diego County offers a potential market for
reclaimed water. Areas of landscaping along freeways include medians, right-of-ways,
and interchanges of Interstate 8 and 67, proposed Route 125, and the planned extension
of Route 52.
The City of Santee irrigates and maintains several landscaped medians of major streets
such as Mast Boulevard, Carlton Hills Boulevard, Mission Gorge Road, and Town Center
Parkway. A significant market for reclaimed water is the irrigation of the many city and
county parks within the study area. Reclaimed water can also be used to irrigate school
yards. Like roadway medians, schools have small potential irrigation demands, but are
easily identified and can be included if near a larger market or distribution pipeline.
Reclaimed water can be used to irrigate common areas in residential neighborhoods and
front lawns of developments in single family areas with proper controls by a home
owners or simular association. Another beneficial use of reclaimed water would be to
irrigate fire breaks behind developments that border canyons, because brush-laden
slopes present a major fire hazard.
For the large undeveloped areas designated as residential use, it was assumed that 10
percent of the area that had slopes less than 25 percent had the potential to use
reclaimed water. Areas with slopes greater than 25 percent were considered
undevelopable.
The potential reclaimed water markets categorized as commercial/industrial
developments include the Santee Town Center, Upper San Diego River Improvement
Project (USDRlP), Edgemore Senior Center/Hospital, Home of Guiding Hands, and the
commercial/industrial parks around Gillespie Field. Three potential industrial markets
were identified which include Woodward Sand and Gravel, Nelson Sloan Sand Plant, and
Precast Concrete.
New potential markets for reclaimed water are the existing or proposed commercial
buildings within the study area. These buildings, if dual plumbed could utilize reclaimed
water. Neither the California Department of Health Services nor the San Diego County
Department of Health Services has approved the use of reclaimed water for indoor
commercial building use due to the questions and potential of cross connections.
Recreational use of reclaimed water includes replenishing the $antee Lakes to make up
water lost by evaporation, consumptive use by plants along the perimeter of the lakes,
and seepage.
The Regional Board believes that stream discharge to the San Diego River has great
potential for both promoting the use of reclaimed water and in enhancing a valuable
riparian habitat. The Regional Board is expected to allow the initiation of a year round
stream enhancement discharge to the San Diego River. As another potential use,
reclaimed water from the Santee WRF could be used as recharge water for groundwater
basins.

1.7 RECLAIMED WATER SYSTEM
The reclaimed water system is based on the Santee WRF being initially expanded to 4.0
MGD. Future expansions of the Santee WRF will provide sufficient reclaimed water for
the subsequent phases of the reclaimed water system.
1.7.1Development of Reclaimed Water System
Transmission and distribution pipelines will be sized to meet peak day demands.
Transmission facilities between pump stations and to reservoirs will be constructed by
the PDMWD. Distribution pipelines to individual markets beyond the Initial Prnject will be
the responsibility of the reclaimed water users. Where reclaimed water is planned to
serve an existing demand, water pressures at least equal to the pressure of the existing
system is required to minimize on-site retrofitting. Similar to the potable water system,
the reclaimed water system will provide a minimum pressure of 30 pounds per square
inch (psi) and a maximum pressure of 200 psi. The pressure zones of the reclaimed
water system will parallel the pressure zones of the potable water system.
Transmission pipeline pump stations will be provided by the PDWMD and will be sized
for peak day demands, pumped over 24 hours. For reliability, a minimum of two pumps
will be supplied; one duty and one standby. Booster pump stations required to serve
individual markets will be the responsibility of the reclaimed water users.
Operational storage is required to match the 24-hour production and the 8 hour irrigation
period. The operational storage required to match the supply and demand is 67 percent
of the peak day demand, and will be provided by the PDMWD.
Hydraulic analysis of the distribution system was accomplished on a micro-computer
using the University of Kentucky's KYPIPE network analysis software. The reclaimed
water system was developed in two phases with the first phase being oversized to
accommodate future facilities and demands.
1.7.2Description of Reclaimed Water System
The Initial System will distribute approximately 3.5 MGD (4.0 MGD less the 0.5 MGD
losses from the Santee Lakes) of reclaimed water from the expanded Santee WRF to
those markets that have existing reclaimed water demands and those markets that are
expected to have demands by 1995 during the peak period. The annual reclaimed water
use will be about 2,216 AF/YR. Of this total reclaimed water use, approximately 366
AF/YR will be discharged to the Santee Lakes. The service area of the Initial System
primarily covers the developed areas of the City of Santee and the community of
Lakeside. The backbone of the distribution system includes a pump station at the
Santee WRF a pump station at the Santee Lakes, and a 30-inch pipeline extending to the
storage reservoir. A 24-inch pipeline continues from the reservoir to the end of the
service area. These pipelines are sized to accomodate the future flows of the ultimate
PAGE 133 Show Image
system. Smaller pipelines will be constructed to connect the system to the users. The
Initial System facilities are sized to accommodate the requirements of the Ultimate
System. The estimated cost for the Initial System facilities is $22,000,000 which includes
engineering, legal and administration, construction managements costs, and
contingencies. The O&M cost for the Initial System are estimated to be $123,000/Yfl.
The Ultimate System consists of a series of transmission pump stations and storage
reservoirs which define separate service areas. Additional distribution pipelines will be
constructed as development occurs. On a peak summer day, the ultimate distribution
system will distribute approximately 14 MGD of reclaimed water throughout the PDMWD.
Annually the Ultimate System will deliver about 7,325 AF/YR through the distribution
system and will discharge about 366 AF/YR to the Santee Lakes. The additional facilities
required for the Ultimate~System, including transmission facilities possibly funded and
constructed by the PDMWD and distribution facilities possibly funded and constructed
by developers, is estimated to cost $51,000,000. The additional O&M would be about
$1 ,180,000/YR.
1.8 CAPITAL IMPROVEMENT PROJECTS
The Capital Improvement Projects (Cl P) are those facilities which will be possibly funded
and constructed by the PDMWD. The ClP schedule for constructing these facilities is
based on the estimated market development, reclaimed water availability, and required
funds. The Initial System is scheduled for construction in Fiscal Years 1991-92 and
1992-93. The CIP schedule lists projects for a 10 Year System and an Ultimate System.
1.9 IMPLEMENTATION
The step to implement a water reclamation program for the Initial System are divided into
several components: environmental and regulatory, planning, and design and
construction. The environmental and regulatory component includes preparing
environmental documentation, obtaining Waste Discharge Requirements and Water
Reclamation Requirements from the Regional Board, and obtaining user agreements or
issuing permits. Planning tasks that must be undertaken include developing a
financial/revenue plan and reclaimed water pricing policy, preparing Rules and
Regulations, developing and executing a public awareness program, and coordinating
planning efforts among agencies. The design and construction component includes the
preparation of a design report; preparation of design plans and specifications; the
advertisement, bidding process, and award of the construction contract, and the actual
construction of the reclaimed water facilities.
1.10 ALTERNATE INITIAL RECLAIMED WATER SYSTEM
A separate analysis was conducted for the initial project without planned expansion and
is included in Appendix G. The smaller facilities constructed for the Alternate Initial
System would not accommodate future flows of the Ultimate System. The alternate
PAGE 134 Show Image
system requires a 14-inch pipeline from the pump station at the Santee WRF to a 3.66
million gallon (MG) reservoir and a 12-inch pipeline from the reservoir to the end of the
system as compared to 30-inch and 24-inch pipelines. For the most part, the smaller
pipelines that connect the users to the system are about the same size in both systems.
The estimated cost~for the Alternate Initial System facilities is $18,000,000 for capital
facilities and $1 12,000/YR for O&M.
From funding and planning standpoints, constructing the Alternate Initial System may be
beneficial. The funding currently available may only be sufficient to construct the scaled
down Alternate Initial System. The future reclaimed water demands of the large
undeveloped areas were estimated based on projected development. The uncertainty of
future demands may warrant constructing only facilities to serve markets with known
demands.
The disadvantage of constructing the Alternate Initial System would be experienced if in
the future it was decided to expand the system. The Alternate Initial System facilities
would have to be upsized to accommodate the increased flows of the expanded system.
Pipelines would have to be paralleled and larger pump stations would have to be
constructed. The original costs of the Alternate Initial System facilities plus the costs to
parallel the pipelines and to expand the pump stations would be greater than if the larger
facilities were constructed initially.

CHAPTER 2
INTRODUCTION
2.1 AUTHORiZATION
The preparation of this study was authorized by the Padre Dam Municipal Water
(PDMWD) in the form of a contract titled "AGREEMENT FOR PROFESSIONAL
ENGINEERING SERVICES BETWEEN PADRE DAM MUNICIPAL WATER DISTRICT
AND LUKE-DUDEK CIVIL ENGINEERS, INC." and dated March 28,1990.
2.2 BACKGROUND
The resolution aufhorizing Luke-Dudek Civil Engineers, Inc. (now Dudek & Associates,
Inc.) to prepare this Water Reclamation Master Plan was approved by the PDMWD
Board of Directors on February 13, 1990 by Resolution No. 90-13. The study was jointly
funded equally by the San Diego County Water Authority (SDCWA) and the PDMWD.
The PDMWD functions as both a water and sewer agency. As a multi-purpose agency,
the PDMWD provides wholesale and retail water; wastewater collection, treatment, and
disposal; water reclamation; and recreational facilities at the Santee Lakes Regional Park
and Campground. The PDMWD has no local supply of water and depends on imported
water purchased from SDCWA. In turn, the PDMWD wholesales water to the Lakeside
and Riverview Water Districts and retails water in the City of Santee, a portion of El
Cajon, and severnl~unincorpornted communities extending eastward including Alpine.
Sewer Service by the PDMWD is limited to the City of Santee, parts of El Cajon, and a
small portion of the County of San Diego.
The PDMWD owns and operates the Santee Water Reclamation Facility (WRF); however,
the PDMWD and the City of San Diego are currently in negotiations concerning the lease
of the Santee WRF site. These negotiations are the result of the City of San Diego's
secondary treatment program and concurrent planning efforts to maximize water
reclamation in the San Diego Metropolitan Sewerage System (METRO) service area.
The Clean Water Program (CWP) for Greater San Diego was created to meet San
Diego's commitment to provide secondary treatment and water reclamation. In July
1989, the CWP published the Water Reclamation and Reuse Master Plan for
Modffications to the Metropolitan Sewage System and the Framework Plan Report for
Modifications to the Mefropolltan Sewage System. Both plans identify water reclamation
facilities in various parts of the METRO service area, including the City of Santee. The
estimated capital cost of the recommended facilities, which would treat approximately
243 million gallons per day (MGD) by the year 2010, is $2.6 billion.
2~1'
PAGE 136 Show Image
Concurrent to the CWP planning, the SDCWA authorized Luke-Dudek Civil Engineers,
Inc. and Black & Veatch, Engineers-Architects to prepare the San Diego River Basin
Reclaimed Water Planning and Development Study (SDRB Study). The SDRB Study was
jointly funded by the SDCWA, PDMWD, and the City of San Diego, and the County of
San Diego who were all mutually interested in developing a feasible water reclamation
plan for the San Diego River Basin Area utilizing an expanded Santee WRF.
The PDMWD recognized the need to continue its efforts to implement a water
reclamation program within its water service area. On November 14, 1989, the Board of
Directors of PDMWD adopted Ordinance No. 89-13, "Ordinance of Padre Dam Municipal
Water District Amending Rules and Regulations of Improvement District A, Water
Division, and Improvement District No. 1 (Water Reclamation)." The adoption of this
ordinance defined the scope of the Water Reclamation Master Plan and authorized its
preparation. The scope and objectives of the Water Reclamation Master Plan are
described below.
2.3 MASTER PLAN OBJECTIVES
The purpose of the Water Reclamation Master Plan (Master Plan) is to define,
encourage, and develop the use of reclaimed water within the PDMWD boundaries. The
Master Plan will provide guidance for the planning, scheduling, budgeting, and
construction of a water reclamation system in the PDMWD.
The Master Plan describes the existing and future sewage system, drainage basins
tributary to the Santee WRF, and the proposed development of the Santee WRF. The
designation of sewage drainage basins tributary to the Santee WRF will allow the
PDMWD to implement permitting, monitoring, and control measures within its boundary,
and to negotiate such measures with agencies outside the PDMWD sewer service area.
The Master Plan identifies sources of potentially poor quality wastewater tributary to the
expanded Santee WRF based on existing wastewater quality data which is also reported
in the Master Plan. The Master Plan also discusses a source control program with
recommendations to preclude the discharge of contaminants, such as salts, that would
be detrimental to~the PDMWD's reclamation program.
Additionally, this Master Plan addresses the PDMWD regulations for reclaimed water use
within its boundaries. The Rules and Regulations will govern the design and operation of
reclaimed water facilities, and are required by the State Department of Health Services
(DHS) and the Regional Water Quality Control Board (Regional Board). The Rules and
Regulations are included in the Master Plan as Appendix I and will be able to be
distributed as a separate document. A Standard Reclaimed Water User Agreement has
also been prepared for the PDMWD's reclaimed water customers and is included as
Appendix J.

A Public Awareness Program, is outlined in this Master Plan. Based on successful
programs by other reclaimed agencies, the Public Awareness Program will provide the
PDMWD with a plan to develop positive public relations on the subject of water
reclamation.
Implementation of the Master Plan is also presented as a schedule for the design and
construction of reclaimed water storage and distribution capital facilities. The capital
improvement projects schedule includes yearly projects for the initial five-year
reclamation program period, projects scheduled for completion by the tenth year of the
program, and projects required for the ultimate system. The schedule is phased based
on the demand and timing of market development, availability of reclaimed water, and
the reasonable availability of funding. Coordination among agencies including the
County of San Diego, City of San Diego, SDCWA, Helix Water District, Lakeside Water
District, Riverview Water District to treat, Lakeside Sanitation District, and the Alpine
Sanitation District purvey, and use reclaimed water is also taken into account in the
schedule.
The Master Plan is intended to be a changing document that is to be updated every five
years.
2.4 ACKNOWLEDGEMENTS
Dudek & Associates, Inc. wishes to acknowledge PDMWD staff, the SDCWA, and City of
Santee staff for their assistance in the preparation of this Master Plan.

CHAPTER 3
DESCRIPTION OF STUDY AREA
3.1 STUDY AREA BOUNDARY AND LOCATION
The study area for this report is defined by the Padre Dam Municipal Water District
(PDMWD) water service boundary. The PDMWD is located about 20 miles from the
Pacific Ocean and about 22 miles north of the U.S. -Mexican border. The western border
is formed by the City of San Diego boundary adjacent the City of Santee and the eastern
border is defined by the National Cleveland Forest boundary. North of the PDMWD lies
the San Vicente and El Capitan Reservoirs and the Barona Ranch Indian Reservation.
The 85 square miles of the PDMWD are comprised of the City of Santee, a portion of the
City of El Cajon, and the unincorporated communities of Lakeside, Flinn Spring,
Harbison Canyon, Blossom Valley, Alpine, Dehesa, and part of the Crest area.
3.2 LAND USE
The existing and projected development within the study area is presented in Table 3-1.
Development of the incorporated areas within the study boundaries is guided by the City
of Santee General Plan and the City of El Cajon General Plan. Development of the
unincorporated areas within the study boundaries are guided by the Lakeside
Community Plan, the Crest/Dehesa/Harbison Canyon/Granite Hills Subregional Plan,
and the Alpine Community Plan which are part of the San Diego County General Plan.
These planning areas are shown on Figure 3-1. Since each area has specific planning
documents, the land use within each area will be discussed separately.
3.2.1Santee
Residential uses in Santee are primarily composed of single family detached units on
standard subdivision lots with some multi4amily developments generally located along
major roadways. Commercial development in Santee occupies 181 acres with the
majority devoted to retail uses. Industrial development is in the form of light industrial
uses characterized by assembly, electronics, research and development, and light
warehousing uses. Office professional development is limited, encompassing about 20
acres. Public/semi-public land uses including schools1 public and private parks, and
churches cover a considerable portion, about 25 percent, of the developed acreage in
the City of Santee. Over half the area of the City of Santee is currently vacant. The
primary vacant areas are undeveloped canyons and hillsides in the north and southeast
and steeply and rolling terrain in the southwest portion of the City of Santee. A significant
portion of vacant acreage is also found along the San Diego River corridor: the floodway,
the flood plain, and large relatively developable parcels.

3.2.2 El Cajon
The El Cajon Planning Area is a part of the metropolitan San Diego area, Only a small
portion of the City of El Cajon is included in the study area, which includes primarily the
Gillespie Field area. Adjacent the airport, the land use designations include both
industrial park and general industrial uses. Approximately 70 acres just southwest of the
field and industrial park is designated open space. The remaining areas of the City of El
Cajon within the study area are, for the most part, designated as residential, ranging
from low density to high density.
3.2.3 Lakeside
Findings in the Lakeside Community Plan report approximately 88 percent of the Current
Urban Development Area in Lakeside is planned for residential use. Single-family plan
designations predominate over about 90 percent of the area planned for urban
residential development. Large-scale agricultural uses have given way to residential
development; however, a considerable amount of small-scale farming still exists in the
community and many homes in the residential areas of Lakeside have small horse
corrals. The Lakeside Community Plan has approximately 300 acres devoted to
commercial uses which are located in the Lakeside Town Center and in other small
commercial developments distributed throughout the Community. The Lakeside
Community Plan identifies three major areas which are currently used for industrial
purposes: the Upper San Diego Improvement Project, the Slaughterhouse Canyon Area,
and the area along Olde Highway 80 east of Lake Jennings Farm Road,
3.3
PAGE 141 Show Image
3.2.4Crest/Dehesa/Harbison Canyon/Granite Hills
The Crest/Dehes.a!Harbison Canyon/Granite Hills Subregion has three primary focal
points of land activity. These are comprised of the three communities of Crest, Dehesa,
and Harbison Canyon. Granite Hills is a developed area but lies outside the PDMWD
boundary. Crest and Harbison Canyon are both communities which retain fairly high
residential densities surrounded by areas of lower density estate development and large
areas of undeveloped land much of which is constrained from development. Small areas
of commercially zoned land exist in each of the communities. According to the
subregional plan, only three percent of the subregional planning area is in agricultural
production because of the severe topography and lack of imported water facilities. The
Dehesa Valley is orientated toward an agricultural lifestyle and although water is limited,
certain crops such as oats and hay are produced. Some small husbandry exists,
primarily horse breeding.
3.2.5Alpine
The Alpine Community Plan area covers 108 square miles situated in the foothills of the
Cuyamaca Mountains. Existing development has a rural character typified by light
agricultural activities practiced in conjunction with residential uses. The pattern for
community development presented in the Alpine Community Plan accommodates
growth in and surrounding the existing town of Alpine, designating the agricultural areas
and remote more mountainous areas for low density rural uses. Residential development
ranging from single family houses on half acre or less to multi4amily units is contained in
the Country Town (Town Center). Major commercial development is generally restricted
to properties along Alpine Boulevard, Arnold Way, and the Tavern Road-Interstate 8
interchange area.
3.3 WATER SUPPLY AGENCIES
A major element in the development of a new water source such as reclaimed water is
the evaluation of existing water supply issues and water quality. Water supply facilities
and water use trends will determine the need for additional water supply and the water
quality needs will establish the suitability of reclaimed water for reuse.
3.3.1Regional Water Supply Agencies
Potable water delivered to the study area is supplied through the vast delivery system of
the State Water Project and the Colorado River Aqueduct by the Metropolitan Water
District of Southern California (MWD) and the San Diego County Water Authority
(SDCWA).
34
PAGE 142 Show Image
The MWD was organized in 1928 and is restricted to the production, transportation, and
distribution of water fdr municipal and domestic purposes. It supplies water to 27
member agencies in Southern California, including the SDCWA, with a combined
population of over 13 million people. MWD's firm supply from its Colorado River
Aqueduct and the State Water Project is anticipated to decrease from 1.97 million acre-
feet per year (AF/YR) in 1987 to 1.39 million AF/YR by the year 2000 unless additional
measures and facilities are initiated. Demand for imported water is expected to increase
from 1.6 million AF/YR to 2.0 million AF/YR during the same period.
MWD now has five pipelines providing service to the SDCWA. MWD's jurisdiction of
these pipelines end at a delivery point approximately six miles south of the Riverside-San
Diego County line at which point the SDCWA takes over.
The SDCWA delivers raw and treated imported water to its 24 member agencies which,
in turn, supply almost 95 percent of the population of San Diego County. The
distribution system of the SDCWA consists of the extension of the aqueducts from the
MWD delivery point to the member agencies throughout the San Diego County. The
primary treated water source is the Skinner Filtration Plants which is owned and
operated by MWD. Some treated water is also purchased from local treatment plants
within San Diego for delivery to other member agencies.
3.3.2Local Water Supply Agencies
The water agencies that serve the study area and adjacent areas are shown in Figure 3-
2.
The PDMWD began in 1977 as the result of the merger of the Santee County Water
District and the Rio San Diego Municipal Water District. As a water agency, PDMWD
sells water on a wholesale and retail basis to the are~ described above. The PDMWD
serves approximately 17,780 water customers. The current average water demand for
PDMWD is about 16 million gallons per day (MGD) (18,200 AF/YR) with a peak day
demand of 25 MGD.
The wholesale water supply system is called Improvement District C. The water for the
PDMWD is purchased from the SDCWA and enters Improvement District C through
connections at the SDCWA Aqueduct Pipeline No. 4 and at the Helix Water District's
R.M. Levy Water Treatment Plant at Lake Jennings. Improvement District C wholesales
water to two other improvement districts, Improvement District No. 1 and Improvement
District A, which are operated by PDMWD as retail water service areas, and to the
Lakeside Water District (LWD) and the Riverview Water District (RWD). PDMWD's
facilities include over 250 miles of water mains, 14 pump stations, 22 reservoirs, and 13
pressure reducing stations. The three largest reservoirs total 51 million gallons (MG) of
storage.

As mentioned1 the LWD purchases its water from PDMWD. As shown on Figure 3-2,
Lakeside Water District is just east of Santee. LWD's major water users are single family
dwellings and apartment complexes. Agricultural irrigation accounts for less than 2
percent of LWD's water use. The distribution facilities include three pump stations, a
booster pump, and five steel tank reservoirs with a total capacity of about 7 MG. LWD
also has a 1 MG reservoir not in use. The District's current demand is approximately
4,500 AF/YR.
The RWD also purchases water from PDMWD and, like the LWD, is responsible for
providing its own distribution system with customer services, billings, disinfection, and
general maintenance. In 1988, the RWD purchased 1,593 acre-feet of potable water
from PDMWD. The RWD has four reservoirs ranging from 0.84 MG to 1.5 MG, with a
total storage capacity of 4.24 million gallons, and several pump stations located in
Lakeside.
The municipal water supply for the study area is treated at either the Helix Water
District's R.M. Levy Treatment Plant or the MWD's Skinner Filtration Plant. In some
areas of the PDMWD, the water sources are blended. Water quality recently reported by
the PDMWD is listed in Table 3-2.

3.4 WASTEWATER AGENCIES
This section provides a brief description of the wastewater collection and disposal
systems within service areas of the study area. Several sewer agencies provide sewer
services to the study area. The these agencies are shown on Figure 3-3.
As previously noted, the PDMWD functions as both a water and sewer agency. The
PDMWD sewage operations serve only the City of Santee Corporate limits and a small
portion of the community of Lakeside and the Pepper Drive are within the San Diego
County. The community of Winter Gardens and parts of Alpine and Lakeside are served
by individual sanitation districts operated by the County of San Diego Public Works
Department. The City of El Cajon operates and maintains sewage collection facilities
within its incorporated areas. Areas not served by a particular sewer agency are served
by on-site septic systems.
Sewage from the City of El Cajon; the Alpine, Lakeside, and Winter Gardens Sanitation
Districts; and about seventy-five percent of the sewage from the PDMWD sewer service
area is discharged into the San Diego Metropolitan Sewage System (METRO) via the
East Mission Gorge Interceptor Sewer (EMGlS). Sewage collected in METRO is treated
at the San Diego Point Loma Wastewater Treatment Plant. The Point Loma Plant
currently provides advanced primary treatment and releases the effluent into the ocean.
A portion of the sewage from the PDMWD sewer service area is pumped to the Santee
Water Reclamation Facility (WRF) which is located- north of Mission Gorge Road in the
western part of the City of Santee. The existing treatment plant facilities and capacities
are discussed in detail in Chapter 6.

FACT SHEET
Padre Dam Municipal Water District has been reclaiming and reusing water for 33 years.
Since 1968, highly treated reclaimed water has been produced from municipal wastewater to
supply the seven lakes in the Santee Lakes Regional Park and Campground. Boating and
fishing are popular activities on the Santee Lakes. Annual attendance at the park is over
290,000 visitor days.
The District is upgrading the treatment plant facilities at the Santee Water Reclamation Plan
to provide additional water for distribution to industrial, governmental and commercial
customers for irrigation. The District, recognizing that future potable water supplies are
becoming more limited, is planning to produce more reclaimed water as an economical source
of additional water. The District is dedicated to offering its customers a drought-proof supply
of water for outdoor irrigation.
Operational Chan~s
The treatment plant upgrade will involve installation of new processes to produce high quality
reclaimed water for the Santee Lakes and outdoor irrigation. A Bardenpho process will
remove organic matter, suspended solids, nitrogen and phosphorous from the water.
Chemical precipitation using alum will remove additional phosphorous. A final filtering
process will remove minute particles, producing a clear product. Chlorine disinfection with a
miminum of a 2-hour detention time will ensure the highest purification and safety standards.
The portion of reclaimed water for the Santee Lakes will be de-chlorinated to protect aquatic
life. Excess reclaimed water will be discharged through the Lakes to Sycamore Creek and
the San Diego River.
Distribution System
A 25-mile distribution system will deliver the reclaimed water to approximately 80 sites in
Santee. To date, the District has installed 10 miles of reclaimed water mains along and under
several city streets. As part of the upgrade project, 15 miles of new pipeline will be added.
All reclaimed and potable water mains are kept completely separate. The major reclaimed
water distribution mains will be along Carlton Hills Boulevard, Mast Boulevard, Magnolia
Avenue (north of Mast), Fanita Drive and Prospect Avenue in Santee.
An existing 1.5 million gallon water storage tank will be converted to hold reclaimed water
for operational (daily) storage. Annual irrigation demands for the system are approximately
325 million gallons. The distribution system is designed to deliver 2 million gallons per day
and will be capable of carrying additional flows to accomodate filture expansions.
PAGE 149 Show Image
Construction Schedule
Construction for the plant and distribution system is scheduled to begin in summer 995
The project plans to deliver reclaimed water to customers by the high irrigation demand
months of summer 1997 -
Ouplity of Reclaimed Water
The reclaimed water will be low in nutrients and suitable for many uses, It is ideally suited
for landscape irrigation of street medians, parks, golf courses and open spaces at commercial
facilities and residential housing. Reclaimed water has a proven safety record. Strict
monitoring controls are always in effect to ensure the safety of the product. The quality of
reclaimed water is regulated by the State Regional Water Quality Control Board with input
from the San Diego County Department of Health Services. Reclaimed water will meet State
Administrative Code Title 22 criteria for the highest level of quality. This level is designated
safe for full body contact. i.e, it is safe for individuals to come into contact with the water.
In order to keep reclaimed water quality suitable for irrigation of all types of plant materials.
the District prohibits the use of self-regenerating water softeners which discharge salt brine
into the sewer system. This local ordinance is in effect throughout most of the District's
sewer service area.
Project Cost and Rates
The cost of the complete project is approximately $20 million. Low interest loans for over
half of this amount have been set aside by the State of California for this project. Additional
sources of funding are available and are being pursued by the District. Reclaimed water rates
will be set by the Padre Dam Municipal Water District Board of Directors.
Customer Application and Connection Process
The general process an applicant would follow is described here:
· Request forms from the Director of Water Reclamation or Customer Service,
· Review the District's Rules and Regulations governing the use of reclaimed water,
· Make the necessary conversions or retrofits as recommended by the District,
· Have the irrigation system inspected by the District,
o Have meters connected to the reclaimed system by the District.
Speaker's Bureau and Plant Tours
The District has a taained Speaker's Bureau available to address businesses, clubs and
organizations. Groups of any number are welcome to tour the Santee Water Reclamation
Plant. Tour requests should be made in advance. For more information, contact Harold
Bailey, Director of Water Reclamation, Monday-Friday 7:00 AM to 3:30 PM, at 448-8600.

FACT SllEET
llISTORlCAL DATA: Ir' 1976. the voters of the District's service area approved the merger of the Santee
County Water District, formed in 1956, into the Rio San Diego Municipal Water
District. formed in 1955. The surviving agency was named the Padre Dam
Municipal Water District and uses 1955 as its origination date. The District is named
for the Old Mission Dam located just a few miles west of Santee. The dam, built
circa 1807, has been named a historic water landmark. It is located five miles east
of the Mission San Diego de Alcala, founded in 1769, the first of California's 21
Spanish missions. The aqueduct and flume supplied water to the mission and are
believed to be the first major non~indigenous irrigation project on the coast.
The District is a multi-purpose public utility providing wholesale and retail water,
wastewater collection, disposal, treatment, wastewater reclamation and recreation in
the Santee Lakes Regional Park and Campground.
SERVICE AREA: Approximately 85 square miles in five improvement districts. Sewer service to the
City of Santee, parts of El Cajon, and the county of San Diego. Water service to the

SEWAGE LIFT The District operates three sewage lift stations and one main sewage pump station.
STATiONS:
RECLItMA TU)N The District~s reclamation plant processes 1 million gallons of wastewater daily
PLAIVT: (mgd) generated from the Santee area. The influent is processed by an activated
sludge secondary treatment process then further treated in oxidation ponds and per-
colation basins, disinfected and treated with alum. The reclaimed water then fills the
seven Santee Lakes. By 1997, the District will increase the treatment capacity of
the plant to 2 mgd, install a BardenPho treatment process, tertiary filters and a
chlorine contact chamber. The additional reclaimed water will be distributed in a
separate system to Santee customers with large irrigation needs.
SANTEE LAKES: The District owns and operates the SANTEE LAKES REGIONAL PARK AND
CAMPGROUND located in the City of Santee. The 190-acre regional park, which
opened to the public in 1961, includes seven recreational lakes and surrounding
parkland. The lakes are filled with reclaimed water and are world-famous as a
unique and successful water reclamation project. The park offers picnicking, fishing
(stocked regularly), boating and camping. There are 152 full hook-up campsites with
complete facilities. The park is open year-round and receives nearly 400,000
visitors annually for day-use activities and overnight camping.
GOVERNING BODY: The District is a public agency governed by a five-member Board of Directors, each
representing a geographic area within the District. Directors are elected by the
voters for staggered four-year terms. Board meetings are open to the public and
are held at 3:30 p.m. the second and fourth Tuesdays of each month at the District's

Reclamation Project Final
II. PROJECT SCRIPTION Subsequent EIR
A. Project Location
Padre Dam MWD is located in San Diego County, about 20 miles from the Pacific Ocean and about
22 miles north of the Mexican border and provides sewer andlor water service to an area of
approximately 83 square miles which includes the City of Santee and the unincorporated communities
of Irakeside, Crest, and Alpine (see Figure 1). The District operates the Santee Water Reclamation
Facility (Santee WRF) which is located immediately north of Santee Lakes Regional Park and
Campground in the northwestern section of the City of Santee. The Regional Park and Campground
is also owned and operated by the District. Figure 2 shows the location of the Santee WRF and the
general area of Santee where reclalmed water will be distributed for landscape irrigation. Access
to the Santee WRF is from Mast Boulevard or Carlton Oaks Drive via either Fanita Parkway or
through the Regional Park and Campground. The District's Field Operations Area is also located
adjacent to Santee Lakes on the north side of Carlton Oaks Drive.
B. Project Objectives
-Padre Dam Municipal Water District provides potable water and sewer service to approximately
12,534 customer accounts, potable water service only to approximately 1,686 customer accounts, and
sewer service only to approximately 1,326 customer accounts in the Cities of Santee, El Cajon, and
the westerly portion of the unincorporated community of Lakeside. The District provides potable
water service to approximately 6,364 customer accounts in the unincorporated communities of
Blossom Valley, Crest, Alpine and Harbison Canyon. The two service areas are not contiguous.
Currently, the district collects approximately 3.0 million gallons per day (mgd) of wastewater. Of
this amount, approximately 4 mgd is conveyed to the San Diego Metropolitan Sewerage System
(METRO) for treatment at the San Diego Point Loma Wastewater Treatment Plant and released into
the ocean via an outfall. One million gallons per day is conveyed via a pump station to the Santee
Water Reclamation Facility (Santee WRF) for reclamation and reuse in Santee laakes and irrigation
of Santee lakes Regional Park. The existing plant is currently rated at 2.67 mgd, however, the
overall treatment process is constralned by the diminished capacity of the percolation beds which
serve as natural filters. The capacity of the natural filtration system is approximately 0.3 mgd.
The purposes of this project and the overall Padre Dam Water Reclamation Project are to:
· Increase the volume of reclaimed water to adequately supply Santee lakes and malntain the
health of this recreational resource.
· Provide a source of reclalmed water for landscape and irrigation, thus off-sening the demand
for potable water. This will be the only source of water over which Padre Dam has control.
· Provide for treatment and disposal of 2 million gallons per day of wastewater to diminish the
volume of wastewater conveyed to METRO.

Raw sewage treated at Santee WRF passes through a treatment process which consists of an extended
aeration activated sludge plant followed by oxidation ponds, percolation basins, chlorination, and
alum clarification. This process results in a level of tertiary treatment which allows discharge of up
to 0.999 mgd in Sycamore Creek and the San Diego River. The reclaimed water from the Santee
WRF is also suitable for use at the Santee Lakes Regional Park and Campground. The park consists
of seven reclaimed water lakes used for fishing and boating, day use picnic facilities, and overnight
camping areas. In addition to replenishing water in Santee Lakes that is lost by evaporation, the
reclaimed water is used on approximately 12 acres of landscaping at Santee Lakes Park.
Reclaimed water from the Santee WRF not used for lake replenishment or on-site irrigation at the
Santee Lakes Regional Park, or lost to evaporation, is discharged into Sycamore Creek from Santee
Lake 1, or is stored in the oxidation ponds for discharge to METRO during off-peak hours.
Discharge from Lake 1 is limited to 0.999 mgd by Padre Dam MWD's National Pollutant Discharge
Elimination System (NPDES) permit. The NPDES permit is more restrictive on the discharge of
reclaimed water during the dry weather months from March through October to prevent
concentrations of nitrogen and phosphorus in the treated water from promoting algal growth in the
low water flows of Sycamore Creek and the San Diego River.
The proposed project will provide an upgrade of the activated sludge process, additional tertiary
treatment equipment at Santee WRF and a distribution system with a reclaimed water reservoir,
pump stations, and pipelines so that the reclaimed water can be used for landscape irrigation along
roadways, at commercial and business locations, at multi-family housing, and at local parks and
schools. The project goal is to provide for the treatment and re-use within the Santee area of 2.0 mgd
of tertiary-treated reclaimed water, with the excess discharged to Sycamore Creek. The existing
oxidation ponds will serve as future reclaimed water storage ponds so that some excess winter flows
can be stored for supplying the Santee Lakes during summer when irrigation demands are high.
C. Proposed Project
The proposed project includes improvements at the Santee WRF Plant Site located at the northerly
end of Santee Lakes, a distribution system for reclaimed water consisting of pipelines and other
improvements located throughout the City of Santee, and flood control and operating system
improvements at the Field Operations Area located on the north side of Carlton Oaks Drive.
1. Plant Site Improvements
The proposed project will utilize existing treatment processes, convert and upgrade some existing
facilities, and construct new tertiary treatment facilities to provide a capacity of 2.0 mgd. Figure
3 is a flow diagram showing how the new treatment facilities will be integrated into the existing
treatment system. This upgraded process will enable wastewater to be treated to a level that permits
public contact ("non-restricted") in accordance with Title 22 criteria of the California Administrative
Code, which is the most stringent standard for reclaimed water use, and for discharge to Sycamore
Creek and the San Diego River Watershed.
The California Regional Water Quality Control Board, San Diego Region (RWQCB) has issued
Order 92-12 which sets requirements for discharge of wastewater to land and governs the use of
4 I~adre I)am Water Reclamation Project ElR
PAGE 154 Show Image
reclaimed water for irrigation; and Order 9348 which sets out requirements for discharge to Santee
Lakes and the San Diego River Watershed, up to a volume of 2.0 mgd.
Primary and Secondary Treatment Process. The primary treatment process will remain
unmodified. Existing primary tanks are covered and malodorous air is withdrawn and introduced
into the aeration basins which serve to reduce the odor. One-half of the existing secondary treatment
tanks will be converted into the five-stage Bardenpho modification of the activated sludge process.
This is a biological nutrient removal process which effectively reduces nitrogen and phosphorous in
the effluent. The process is also effective at removing suspended solids and suspended and dissolved
organic material from the wastewater. The existing clarifiers will be utilized without modification.
Process pumping will be upgraded where necessary.
Tertiary Treatment Process. The addition of tertiary treatment facilities requires new operating
equipment and structures. Figures 4 and 5 show the existing Santee WRF and the proposed and
future facilities. The major components of the process include two flocculation basins and
sedimentation tanks to provide coagulation, precipitation of phosphorous as an insoluble alum salt,
and clarification. The next process is denitrification filters where methanol is added in low doses
to facilitate conversion of nitrate to nitrogen gas while filtration to remove particulate matter is
achieved. Chlorine solution is then added as a disinfectant, and held in contact for two hours. Flow
for the reclaimed water distribution system will go directly to the reclaimed water pump station.
Flow for Santee Lakes or for storage in the existing oxidation ponds will be de-chlorinated by the
addition of sulfur dioxide.
Other Improvements. Other improvements are provided to support the main process described
above. Improvements to the chlorine storage and chlorine feed rooms will be made. A chlorine
scrubber will be provided to neutralize any chlorine that escapes in the containment rooms. A
chemical storage area with a containment structure will be built. A new dechlorination building will
be provided. Other improvements are a new paved access road, various sidewalks, stairs, ramps and
safety railings. The existing operations building will be converted into a multipurpose room and
other support offices. The existing denitrification building will be converted to office spaces. The
existing control building will be modified into a larger laboratory, a control room, and office spaces.
Two existing tanks will be converted to a sludge fermentation tank and a washwater recovery tank.
An odor control system will be provided for the sludge fermentation tank. All improvements are
to be constructed within the existing graded and fenced plant area. Figure 6 is an elevation of the
proposed facilities as would be viewed from the east, looking west. New landscaping would also
be installed throughout the plant area.
Chemicals Stored and Used On-Site. The following chemicals will be stored and used on-site:
· Chlorine gas in 1-ton containers
· Alum solution
· Polymers in liquid form
· Methanol
· Sulfur Dioxide in 1-ton containers.
· Sodium Hydroxide in liquid form in the chlorine gas scrubber.
· Sodium Hypochlorite in liquid form
Padi: Dam Wa&:r Rcciamauon Project EIR II
PAGE 155 Show Image
Future Improvements. The plant is designed to be upgraded to a 4.0 mgd facility by additions to
the flocculation/sedimentation facility, filters, chlorine contact basins, and an additional secondary
clarifier. These fliture improvement locations are also shown on Figures 4 and 5.
Failsafe Disposal ~r Treated Effluent. The proposed project is required to have an alternative
failsafe method of effluent disposal pursuant to Title 22, Division 4, Chapter 3, Reclamation Criteria,
of the California Administrative Code. One failsafe method proposed by the project is live-stream
disposal to Sycamore Creek. The Santee WRF, pursuant to its NPDES Permit, is presently allowed
to discharge up to 0.999 mgd to Sycamore Creek and will be allowed to discharge 2.0 mgd when
the upgrade is complete. Additionally, the Padre Dam MWD has an agreement with the City of San
Diego to convey up to 6.22 mgd of raw sewage to the METRO System. This bypass system, along
with discharge to Sycamore Creek, would provide failsafe disposal for the proposed project.
Water Redamation Master Plan. The proposed project would implement a portion of the Padre
Dam Municipal Water District Water Reclamation Master Plan, prepared for the Padre Dam MWD
and the San Diego County Water Authority in February, 1991. The proposed project would
implement only the initial components of the Master Plan and would not implement the Ultimate
System, which would serve an expanded reclaimed water market and would encompass a much larger
distribution system (see Section 6.1.2 of the Padre Dam MWD Water Reclamation Master Plan) than
that presently proposed.
2. Distribution System Improvements
The proposed system would distribute approximately 800 to 1000 acre-feet annually of reclaimed
water from the expanded and upgraded Santee WRF to reclaimed water markets as listed in
Appendix D. These reclaimed water markets include landscaping for schools, parks, roadways, open
space, commercial and industrial developments, and a hospital. Transmission and distribution
pipelines would range from 4" to 20" in diameter. Transmission facilities between pump stations
and markets would be constructed by the Padre Dam MWD and are proposed to extend
approximately 80,000 linear feet. The proposed distribution pipelines, as well as approximately
55,000 feet of existing pipelines, are shown on Figure 7. Table 1 is a detailed list of the proposed
pipelines to be installed. Caltrans would install pipelines for landscape irrigation for the extension
of Highway 52 from Big Rock Road to Fanita Road.
The service area of the reclaimed water distribution system generally conforms to the developed
areas of the City of Santee, as reclaimed water markets with an existing demand and location near
the Santee WRF were selected to minimize system cost. An existing 6" line in Mast Boulevard
extends into the City of San Diego and would serve Sycamore Canyon landfill. Water pressures at
least equal to the pressure of the existing system is required to minimize onsite retrofitting. Similar
to the potable water system, the reclaimed water system would provide a minimum pressure of 25
pounds per square inch (psi) and a maximum pressure of 200 psi. The pressure zones of the
reclaimed water system would parallel the pressure zones of the potable water system.
Fanita Terrace Reservoir, also shown on Figure 7, would be taken out of service as a potable water
reservoir and used to provide the necessary hydraulic gradient to maintain system pressures. The
same capacity, 1.5 million gallons, would be maintained and minor repair and rehabilitation work
would be conducted prior to use as a reclaimed water reservoir. A potable water booster pump
12 Padrc Darn WaLcr Rectampuon Projcct EIR
PAGE 156 Show Image
station would be constructed within the graded or paved area adjacent to the reservoir in order to add
potable water to the system if needed to maintain a reliable supply to reclaimed water users. A new
larger potable water reservoir, known as Mesa Road Reservoir, is to be constructed in the ft:ture
approximately one mile east of Fanita Terrace Reservoir as a separate project.

Please note that the Final Mitigated Negative Declaration referenced in Section 1, herein, addressed
four pipeline routes which have been deleted from the proposed project: Rancho Fanita Drive from
Organdy latne to Mesa Road was deleted because a portion of Rancho Fanita Drive is not currently
an improved street and surveys for biological and archaeological resources may need to be conducted
for this route; Mesa Road southerly of Mesa Heights Road was deleted because of biological and
archaeological considerations and because an alternative route within the Future Highway 125 may
be available in the future to serve Grossmont College; Magnolia Avenue from Prospect Avenue to
Park Avenue is not needed for existing reclaimed water markets to be served in this pipeline
construction phase; and Carlton Oaks Drive from Inwood Drive to Weathersfield Road is not needed
for existing reclaimed water markets to be served in this pipeline construction phase.
3. Operations Area Improvements
The Padre Dam MWD Operations Area is located on the north side of Carlton Oaks Drive adjacent
to the main entrance to the Santee Lakes Regional Park and Campground. Sycamore Creek borders
22
Padre Dam Water Reclamauon Project EIR
PAGE 158 Show Image
the Operations Area on the west side. An existing influent pump station would be modified and
flood protection improvements would be installed at the Operations Area.
Proposed improvements within the Operations Area are shown on Figure 8 and described as follows:
Flood Protection Improvements. Flood control improvements designed for 100-year storm
protection are proposed along the north, west, and south side of the Operations Area and at
the southwest corner of Santee Lake 1. The improvements consist of a wall to replace an
existing block wall and fence on the west and south side of the Operations Area, a concrete
dike and fence to replace a fence along the north side, a storm drain outlet on the south side,
and various drainage sumps and pipes to direct surface drainage to the storm drain outlet on
the south side of the Operations Area. A concrete dike approximately 70 feet in length
would be installed at the southwest corner of Lake 1 to match grade elevation 324.0 and
prevent overflow of the lake into the Operations Area during a storm or flood.
Approximately 8,000 square feet at the Operations Area entrance adjacent to Carlton Oaks
Drive would also be re-graded to improve Site drainage and flood protection.
Pump Station Improvements. The existing influent pump station located at the Field
Operations Area will be upgraded and fitted with a new odor control system. The upgrade
will consist of comminutors to grind large particles in the wastewater, a low lift pump system
to convey wastewater to METRO and to feed the high lift pumps which convey wastewater
to the Santee WRF. Compressed air will be added to the force main to help control
generation of hydrogen sulphide which causes odors at reclamation plants.
D. Environmental Setting
Potential project impacts will occur throughout the Santee area as a result of the proposed
construction of a system of reclaimed water distribution pipelin-es. More location-specific potential
impacts will occur in the vicinity of the Santee WRF and Padre Dam MWD Field Operations Area
located at the north and south ends, respectively, of the Santee Lakes Regional Park and
Campground.
The City of Santee is a growing community distinguished by its location along both sides of the San
Diego River. Incorporated in 1980, Santee has seen the development of new housing projects and
a regional commercial district known as Santee Town Center. Although sensitive native habitats
occur within the City, the majority of natural biological resources have been disturbed by urban
development and other human activities. The San Diego River corridor through Santee has been
altered by high flood waters, sand extraction activities, flood control improvements, and recreational
uses. In general, native riparianloak woodland and non-native ruderal vegetation exists in the
undeveloped drainages while chaparral and coastal sage scrub dominate the upper slopes in the
southern and northern portions of the City. Freshwater habitat also exists within Santee Lakes and
in the San Diego River, Sycamore Creek, and Forrester Creek.
Significant natural areas within the City include the northern portion of the City where coastal sage
scrub and chaparral cover the hillsides and seasonal drainage flows toward Sycamore Creek; the
southwestern area of the City which contains portions of the steep, chaparral-covered slopes of
Padre Dam Water Reciamauon Project ~lR 23
PAGE 159 Show Image
Cowles Mountain and the Mission Trails Regional Park; and Rattlesnake Mountain in the
southeastern portion of the City dominated by coastal sage scrub.
Improvements proposed at the Santee WRF will occur within the fenced plant area on an existing
graded and cleared pad. The WRF is adjacent to the undeveloped Fanita Ranch area located to the
east and northeast. The nearest existing homes are approximately one-half mile to the southeast.
West and north of the Santee WRF is vacant land within the Miramar Naval Reservation; and to the
south is Padre Dam MWD's Santee Lakes Regional Park and Campground. Future development of
Fanita Ranch east of the Santee WRF is expected to result in up to 3,500 residential units, support
commercial uses, parks, natural open space, and a school.
With minor exceptions, improvements at the District's Field Operations Area will also occur within
the fenced and developed District land located east of Sycamore Creek on the north side of Carlton
Oaks Drive. The exceptions are a drainage outlet and grading which will extend into a landscaped
area on the south side of the fenced Operations Area; and a flood control dike to be installed at the
southwest corner of Santee Lake 1.
The Field Operations Area is bounded by Sycamore Creek on the west and Santee Lakes to the north
and east. West of Sycamore Creek is a residential area approximately 300 feet to the west of the
Operations Area; and on the south side of Carlton Oaks Drive is a residential area located
approximately 200 feet south of the Operations Area.
Sycamore Creek is an ephemeral stream nine miles long that originates southeast of the City of
Poway and dralns approximately 18 square miles of land to the north and west of Santee Lakes.
South of Carlton Oaks Drive, Sycamore Creek flows through the Carlton Oaks Golf Course as it
joins the San Diego River.
Much of the existing vegetation in the adjacent portion of Sycamore Creek was removed for flood
control in 1986. Adjacent to the Operations Area is a naturalized channel between 175' and 400'
wide. Over the years it has become revegetated with a mixture of native and non-native species
which is predominantly southern willow scrub (Padre Dam, 1989). Along the west side of the
Operations Area, a 6' chain link fence and/or a block wall 3, to 4' high separates the Operations
Area from Sycamore Creek.
West of the wall/fence is a level area of 5' to 6' in width and a slope 4' to 5' in height to the
Sycamore Creek streambed. The total overall distance from the wall/fence to the streambed is a
minimum of approximately ten feet. The slope bank and level area along the east side of Sycamore
Creek contains a mixture of willows, Brazilian and California peppers, oleander, yew pines, fan
palms, and wild grape which provide a visual screen for the Operations Area. Ice plant (Carpobrotus
edulis), giant reed (Arundo donax), hottentot fig (Carpobrotus edulis), African umbrella plant
(Cyperus alternifolius), and pyracantha also occur in this area. In addition to willows, native species
within the southern willow scrub (riparian) vegetation along the Sycamore Creek streambed include
chaparral broom, buckwheat, sage, mule-fat (Bacchait salicifolla), and lowland cudweed
(Gn~phallum paiustre).
The Biology Report (Padre Dam, 1989) for the Water Reclamation Project surveyed this portion of
Sycamore Creek for least Bell's vireo and other sensitive wildlife and individual plant species. While
24 Padrc Darn WaLcr Rcciamauon Project ~R
PAGE 160 Show Image
none were observed, sensitive species were identified in similar nearby habitats. Some of these
sensitive wildlife and plant species would be expected to occur in Sycamore Creek. The Biological
Resources section of this EIR further describes existing habitat conditions in Sycamore Creek.
E. Background
The Padre Darn MWD functions as both a water and sewer agency. Its current wholesale and retail
water operations serve approximately 120,000 customers with an average water demand of about 18
mgd. The District depends on imported water purchased from the San Diego County Water
Authority to serve the City of Santee, a portion of the City of El Cajon, the Lakeside and Riverview
Water Districts, the community of Crest, and other unincorporated areas to the east, including the
community of Alpine.
Sewage operations by Padre Dam serve only the City of Santee, small areas within the community
of Lakeside located east of Santee and a small unincorporated area located north of El Cajon (Pepper
Drive). Approximately 80 percent of the District's sewage effluent is discharged to the METRO
system and is conveyed via the East Mission Gorge Interceptor Sewer (EMGIS) and the East Mission
Gorge pump station and force main to Point Loma Treatment Plant and ocean outfall. The City of
El Cajon and Sanitation Districts for Lakeside, Alpine, and Wintergardens also utilize EMGIS for
conveyance to METRO.
The Santee WRF has been in operation since 1968. As discussed in the Project Objectives (Section
II.B, herein), the treatment plant is currently rated at 2.67 mgd, and is further constrained by the
diminished capacity of the percolation beds which serve as natural filters. The District's NPDES
permit allows the discharge of up to 0.999 mgd of tertiary treated water into Sycamore Creek and
the San Diego River watershed.
In 1989, Padre Dam MWD certified the Final EIR for a proposed capacity increase at the Santee
WRF to 4.0 mgd; and in 1991 adopted the Water Reclamation Master Plan which had been prepared
for the District and the County Water Authority. These documents were prepared to enable the
District to increase its discharge of tertiary treated effluent into the San Diego River, and to promote
beneficial use of reclaimed water for recreation and landscape -irrigation. As noted earlier in this
EIR, following these actions by the District, RWQCB issued Order 92-12 which sets requirements
for use of reclaimed water for irrigation, and Order 9348 which sets requirements for discharge to
Santee Lakes and the San Diego River, up to a volume of 2.0 mgd. The proposed project will
enable the District's objectives and the RWQCB requirements to be met.
In June 1994, Padre Dam MWD submitted to the City of Santee a completed application to modif~
the Santee WRF's Conditional Use Permit P67-129 which had originally been granted by the County
prior to Santee's incorporation. A Mitigated Negative Declaration, incorporated herein by reference,
was prepared by City staff. A hearing on the application was held by the Santee City Council on
August 10, 1994. Following this hearing, the District determined to prepare this Subsequent EIR
to address in more detail issues raised by the City and the public.
Padre Dam Water Rcciamauon PmJccL EIR 27
PAGE 161 Show Image
E. Growth Inducement
The California Environmental Quality Act (CEQA) requires that environmental documents evaluate
whether a proposed project would induce direct or indirect growth of population, economic
development or housing construction. This includes projects which remove obstacles to growth by
accommodating additional population or construction, such as expansion of public service facilities
(Public Resources Code Section 21100; CEQA Guidelines Section 13212g).
Growth inducement is defined by the San~Diego Association of Governments (SANDAG, 1987) as
any action or circumstance which produces population and/or economic growth in excess of
established projections. The causes of growth typically involve a complex and varied relationship
among several factors including economic setting, employment opportunities, natural population
increase, public policies, and local environment. All of these can influence the rate and extent of
growth, although economic and employment opportunities (and to a lesser extent local birthrates) are
considered the most important factors in the San Diego Region (SANDAG, 1987). That is,
regardless of the environmental amenities or favorable local attitudes toward growth in specific area,
significant sustained population growth will normally not occur without adequate employment
opportunities.
If it is determined that a particular project would induce growth, then the secondary effects of that
growth must also be addressed. These may include effects to resource values such as traffic, air
quality, and public services resulting from additional population and/or construction. Because
population and/or economic growth typically produce a varied range of effects which occur
simultaneously, attempts to label growth as categorically beneficial or adverse are considered
subjective. CEQA Guidelines state (Section 14125g) that growth in any area should not be assumed
as necessarily beneficial, detrimental, or of little significance to the environment.
The proposed project would entail construction of sewage treatment plant improvements and a
reclalmed water distribution system by Padre Dam MWD for the City of Santee and certain adjacent
areas. The District presently owns 6.22 mgd of capacity in the METRO system, and is permitted
by Regional Water Quality Control Board to release 0.999 mgd of treated wastewater. The upgrade
will allow treatment and release of 2.0 mgd of treated wastewater, but will not change the District's
capacity allocation in METRO.
Although no additional sewage treatment capacity is being created at the Santee WRF, the avallability
of reclaimed water for Title 22 uses and the concomitant additional avallability of potable water will
reduce the District's dependance on imported water. Dependance on imported water has resulted
in voluntary water conservation efforts and tiered pay schedules for water during times of drought.
Dependance on imported water has not been a deterrent to development. SANDAG has recently
released Series 8 Growth Projections that have been revised downward from Series 7 projections.
50 Padre Dam watcr Rcciamauon Projoct ElR
PAGE 162 Show Image
While the exact rate of growth and date that build-out will be reached is not specified by SANDAG,
there is little uncertainty that the population of the metropolitan San Diego region, including Padre
Dam's service area, will continue to grow.
The project would reduce the demand for potable water by replacing its use for irrigation. Pipelines
are proposed through developed areas and are intended to accommodate planned growth in
accordance with the Santee General Plan. The proposed project would not extend public services
or access into any areas where they previously were not available.
The proposed distribution of reclaimed water is not considered growth inducing pursuant to CEQA
for the following three reasons:
1. Water reclamation targets specific market demands rather than basic service needs. That is,
reclaimed water has limited applications and cannot meet water needs for most types of
development in and of itself. Specifically, this includes uses such as human consumption and
most domestic applications (cooking, washing, bathing, etc.). Thus, the availability of
reclaimed effluent would not induce growth in population or housing beyond established
projections.
2. Proposed reclamation uses are limited predominantly to irrigation demands which are
currently met with potable water. In the absence of reclamation, priority demands would
continue to be met with potable water. Specifically, proposed reclamation uses which require
irrigation to remain solvent (such as commercial agriculture) are likely to receive a priority
for potable water supplies if reclaimed effluent were unavailable. The proposed use of
reclaimed water would thus not induce additional economic development, as such uses would
have access to other (potable) water sources if necessary. Certain irrigation uses (such as
freeway landscaping) may become more directly dependent on reclamation, although these
irrigation uses are considered an incidental factor in the timing and rate of growth.
3. Viable reclamation markets require demand and cost factors to enable reclaimed water to be
economically competitive with the use of potable water. Such market conditions are subject
to change with a number of parameters, including seasonal or long-term climatic variation.
Thus, reclaimed water demand and use can vary substantially, independent of local
population growth.
The proposed use of reclaimed water could conceivably increase the supply of potable water available
for development. That is, the use of reclaimed effluent for irrigation would free up potable water
for uses such as human consumption. This would not be considered growth inducing pursuant to
CEQA, for the following reasons:
1. The availability of additional potable water in association with the proposed project would
not be growth inducing in and of itself. Substantial shortfalls of potable water in the San
Diego region may occur over the next 20 years, even with significant conservation measures.
Additional potable water associated with the proposed reclamation project is thus not expected
to significantly offset forecasts of regional water supply needs. in addition, Padre Dam's
proposed treatment plant and distribution system improvements are not designed to provide
potable water in excess of established regional growth projections. Instead, the proposed
hdr: Dam Watcr Rcciamatwn Project EiR 51
PAGE 163 Show Image
project seeks to reduce Padre Dam's dependence on METRO for sewage treatment, while
also maintaining Santee Lakes as a recreational resource for the region.
2. The availability of additional water supplies in and of itself would not induce growth due to
the growth management policies already in place. The City of Santee General Plan contains
goals, objectives, and policies to direct growth to planned development areas and to manage
and control growth within the City. Other goals, objectives, and policies of the Santee
General Plan limit development in areas of environmental sensitivity or where public safety
hazards exist. Specific techniques to implement growth control measures include land use
designations and zoning classifications to control the type and density of local development,
requiring specific plans for development of significant new projects such as Fanita Ranch,
and requiring development fees to ensure adequate public facilities and services.

CHAPTER 2 - SECTION 10632 - iC
ic. (Recycled water) A description and quantification of the
potential uses of recycled water, including, but not limited to,
agricultural irrigation, landscape irrigation, wildlife habitat
enhancement, wetlands, industrial reuse, groundwater recharge,
and other appropriate uses, and a determination with regard to
the technical and economic feasibility of serving those needs.
In 1990, the District commissioned engineering consultants, Dudek
and Associates to develop a Water Reclamation Master Plan. The
plan was adopted by the District's Board of Directors on January
22, 1991, Resolution 91-7.
Included in this subsection are several pages taken from the
Water Reclamation Master Plan which address reclaimed water
markets. The market survey assumed the potential 4 MGD project,
Phases I and Ii. See attached Chapter 7 from the Water
Reclamation Master Plan.
It should be noted that since the time of the preparation of the
Water Reclamation Master Plan, the reclaimed water markets for
the Phase I Upgrade Project (2 MGD) have been refined for the
demand levels and distribution feasibility project for the high
irrigation demand season of 1997.
Additional information on the 2 MGD project is provided in the
Santee Water Reclamation Facility" brochure and the initial
Reclamation Project community newsletter, dated August 1995. See
attached.
At the completion of upgraded facilities at the District's Santee
Water Reclamation Plant, the production of reclaimed water will
increase to 2 MGD. This will supply approximately 10% of the
daily water demands in the District.

CHAPTER 7
RECLAIMED WATER MARKETS
7.1 MARKET RESEARCH
Information on potential reclaimed water markets was obtained through a variety of
resources. The San Diego River Basin Reclaimed Water Planning and Development
Study (SDRB Study) by Luke-Dudek Civil Engineers, Inc. and Black & Veatch Engineers
Architects provided an initial list of potential reclaimed water markets for the areas of
Lakeside, Crest, and the City of Santee. Additional markets within the study area were
identified through meetings and telephone interviews with several agencies, including the
Cities of Santee and El Cajon Planning Departments, and the San Diego County
Planning and Land Use Department, San Diego County Parks and Recreation
Department, and the Padre Dam Municipal Water District (PDMWD). Customers with
relatively large water demands were identified from PDMWD water records. The school
districts within the study area were also contacted. Additional resources used to identify
and evaluate potential reclaimed water markets include the Lakeside Community Plan,
Alpine Community Plan, Crest/Dehesa/Harbison Canyon/Granite Hills Subregional
Plan, the City of Santee General Plan and Land Use Plan, and the City of El Cajon
General Plan.
A list of potential reclaimed water users was prepared from the above sources. An
attempt was made to contact each potential user by telephone. Information confirmed
and compiled from telephone calls and site visits includes the following: the type of use,
whether that use is seasonal or uniform, the quantity of water used annually and
seasonally, the quality of water required for that use, the pressure requirements to serve
that market, the owner's interest in use of reclaimed water, and the future plans for water
use at that location. It should be noted that the limitation set for the market research was
a minimum of 5 irrigable acres (or equivalent potential water use); however, smaller
markets that were identified in the course of the research were included in this study.
7.2 DESCRIPTION OF POTENTIAL MARKETS
For the purposes of this study, the term "reclaimed water market" was used to identify a
location where reclaimed water could be used to replace the use or future use of
municipal (potable) water. Reclaimed water can also be used to replace the use of
groundwater or improve the quality of the groundwater that is being used, especially for
irrigation purposes. Enhancement of riparian habitats is also a productive use of
reclaimed water according to the Regional Water Quality Control Board. These uses
were considered potential "reclaimed water markets" in this study.
7-1
PAGE 176 Show Image
The reclaimed water markets were divided into five main categories: irrigation uses,
industrial uses, commercial building uses, recreational uses, and ecological
enhancement. The irrigation markets were~subdivided into the following groups:
agricultural and nurseries, golf courses/country clubs, parks, schools, medians/right.of.
ways (R.O.W.)/interchanges, residential developments including mixed uses such as
commercial center, and commercial/industrial developments. Specific markets are
shown on Figure 7-1. The markets in Figure 7-1 are numbered from west to east and
north to south. Table 7-1 summarizes the potential reclaimed water uses in the PDMWD.
Table 7-I lists the annual water use in acre-feet (AF) and the peak daily water use in
gallons per day (gpd). The annual water use is totaled at the bottom of Table 7-1. Peak
daily reclaimed water use in 1995 is estimated to be approximately 8.1 million gallons per
day (MGD) with an average annual use of 4,360 acre-feet per year (AF/YR) and
increasing to approximately 16.8 MGD peak daily use and 8,865 AF/YR for ultimate
buildout.
An expanded version of Table 7-1 is included in Appendix D. Appendix D shows the
estimated demand for 1995, 2000, and for the ultimate buildout.
For irrigation markets, the number of total acres, if known, and irrigable acres is noted.
The use factor, or application rate in the expanded table applies only to irrigated areas
and refers to the number of acre4eet per acre per year (AF/AC/YR) that is used at that
location. The criteria used to develop the use factor are described in detail in sections
that follow. Appendix D also lists the water district, planning area, hydrographic subarea
(HSA), approximate distance from the Santee Water Reclamation Facility (WRF), and the
source from which the information was obtained. Appendix D also contains a list of
markets sorted and subtotaled by water district, planning area, and HSA.
7.2.1Irrigation Water Demands
Irrigation uses of reclaimed water may include~the irrigation of pastures, crops,
nurseries, golf courses, cemeteries parks, campuses, and residential, commercial, and
freeway landscaping. Both public and private facilities are included in this study as
potential reclaimed water markets.
7.2.1.1 Variations in Irrigation Demands
7.2.1.1.1 Seasonal Demands
Irrigation water demands are non-uniform, varying seasonally from the effects of wet and
dry weather periods. The seasonal nature of crops also effects the water demands of
agricultural irrigation. Peak applications are applied during the dry summer months, and
low applications occur during the wet winter months.
7-2
PAGE 177 Show Image
Individual irrigation user water consumption data and recent seasonal irrigation water
use estimates devetoped by the San Diego County Water Authority (SDCWA) were used
to develop a composite seasonal water demand curve. Comparisons with previous
seasonal demand curves used in past water reclamation studies for several San Diego
County communities were also made. Table 7-2 presents the seasonal demand data
used in this report, in which the demand in August is 2.12 times the average month
demand.
Table 7-2
Seasonal Variation in Irrigation Demand Values
Ratio of Peak Monthly
Percent of Use Rate to Average
Month Total Annual Demand Monthly Use Rate
January 2.5 0.29
February 3.0 0.39
March 4.5 0.53
April 5.5 0.67
May 7.0 0.82
June 10.0 1.22
July 17.5 2.06
August 18.0 2.12
September 12.5 1.52
October 9.0 1.06
November 6.0 0.73
December 4.5 0.53
The precise annual irrigation demand pattern will vary slightly from location to location
depending on climate, soil conditions, method of application, type of vegetation, etc.
The changes due to seasonal demand, however, will generally follow the pattern shown
in Table 7-2.
7.2.1.1.2 Irrigation Application Rates
The amount of water required for irrigation is dependent on the type of vegetation, soil
type and condition, hours of daylight, temperature, topographic and geologic conditions,
and the method of irrigation water application. The net irrigation water required over a
specified period of time defined as the depth of water needed to meet the water loss
through evapotranspiration, leaching, seed germination, climate control, frost protection,
and fertilizer application. In San Diego County, rainfall provides only a fraction of the net
irrigation water requirement for most plants. Irrigation systems are designed to apply
enough water to supplement the amount of water provided by rainfall, and satisfy the net
irrigation requirement.
7-9
PAGE 178 Show Image
Methods for determining irrigation application rates are based on the reference
evapotranspiration rate, the rate of precipitation, and efficiency factors associated with
the application method, and the type of crop and crop coefficients. Evapotranspiration
rates are dependent on the type of vegetation and climate. Precipitation rates in the
study area of this report average 12 inches per year near the coast, and 14 inches per
year inland. Application efficiencies for irrigation distribution systems typically range
from 70 to 80 percent.
Precipitation rates in the study area of this report average about 12 to 14 inches per
year. Application efficiencies for irrigation distribution systems typically range from 70 to
80 percent.
The SDCWA estimates the total water requirement for vegetation in coastal San Diego
County to range from 30 to 45 inches per year. Of this amount approximately 12 inches
is provided'by rainfall. Therefore, irrigation must provide 18 to 33 inches of water to
meet this requirement.
For this report, an average applied water irrigation demand of 30 inches per year (2.5
AF/AC/YR) was used for landscape irrigation markets unless more specific data was
available from the user or water records. The applied water irrigation rates for each
market is listed in the expanded table presented in Appendix D.
7.2.1.2 Agricultural and Nursery Irrigation
Three areas of agricultural production are included as potential markets for reclaimed
water use: the 560 acre avocado grove of Rios Canyon Ranch, 28 acres of avocado
production along La Cresta Road, and approximate 600 acres of land designated as
agriculture preserve located in the Lakeside Community Plan. It was estimated that 25
percent of the 600 acres have the potential to use reclaimed water.
As presented in Chapter 5, Table 5.7 lists the TDS and chloride tolerances of avocados
as 800 mg/I, and 100 mg/I, respectively. Recent records indicate the Santee WRF
effluent chloride levels exceed 200 mg/I. As discussed in Chapter 6, the chloride level of
future reclaimed water is not likely to vary significantly from the current quality unless
protective measures are taken. Blending this quality of reclaimed water with the quality
of potable water presented in Chapter 3 at a rate of 75 percent potable water and 25
percent reclaimed water, achieves a quality of irrigation water below the tolerances of
avocados. Therefore, a rate of 0.625 AF/AC/YR was used for the two avocado groves.
Three large nurseries were identified in the study which include the Lakeside Pinery,
Rancho Johoba Nursery, and Colorspot El Cajon. The 16 acre Lakeside Pinery is
expected to be developed for commercial/industrial use within 5 to 7 years.

7.2.1.3 Golf Course Irrigation
Golf courses provide a practical market for reclaimed water due to their large irrigation
demands. Reclaimed water is typically used to irrigate golf course fairways and roughs.
Greens and tees are sometimes maintained with potable water because of the sensitivity
of the grasses and the desire to keep these areas in top condition. Golf course
superintendents are concerned with the quality of the reclaimed water, its impact on golf
course turf, and the cost of reclaimed water. The Golf Course Water Conservation
Group was formed in San Diego County to address the issue of water conservation at
golf courses in a potential drought situation. The group consists of golf course
managers, develdpers1 irrigation system manufacturers and vendors, and others
involved in the local golf course industry. The group intends to be involved with the
development of reclaimed water as a resource and to represent the needs of the golf
course industry.
The Carlton Oaks and Willowbrook Country Clubs maintain two golf courses within the
study area. Currently, storm runoff collected from the San Diego River is used to irrigate
the Carlton Oaks Golf Course Due to the current and past drought conditions
personn~l of the Carlton Oaks Golf Course will be evaluating their water demands
sometime in August. At that time they may consider options such as drilling a well.
Although the Carlton Oaks Golf Course Superintendent describes the quality of the
irrigation water as "not great", he sees no benefit to the golf course to purchase
reclaimed water. Therefore1 reclaimed water service is not proposed to the Carlton Oaks
Golf Course in this Master Plan. The Willowbrook Country Club currently uses well water
for irrigation. Personnel at the Willowbrook Country Club do not see an immediate need
for reclaimed water but do feel that reclaimed water may be required in the future since
the future quality of the well water is uncertain.
Three additional golf courses in the planning stages were also identified. Golf courses
are planned for the Fanita Ranch, Alpine, and High Meadow Ranch developments. The
Fanita Ranch Golf Course will be about 175 acres; however, since it is likely that much of
the golf course will remain in a natural state with no irrigation and since no details are
available, it was assumed that 60 percent of the 175 acres will be irrigated. An 80-90
acre golf course is planned for the High Meadow Ranch development. According to the
developer, the golf course is designed for reclaimed water use when it becomes
available. On-site treatment and reuse of wastewater as an irrigation supply for the golf
course is being planned for the Alpine development, therefore, this golf course will not be
included in the service area..
As an imported factor in the system planning presented in Chapter 8, each golf course
has, or will have, on-site storage; therefore, reclaimed water can be served to each golf
course over a 24 hour period.

7.2.1.4 Freeway and Median Landscape Irrigation
Water use by the California Department of Transportation (CALTRANS) for irrigation of
landscape along freeways within San Diego County offers another potential market for
reclaimed water. Areas of landscaping along freeways include medians, right~of~ways,
and interchanges. Interstates 8 and 67, proposed Route 125, and the planned extension
of Route 52 present opportunities for reclaimed water use. Not only are these routes
large potential markets, but a recent amendment (September 1989) to Senate Bill 488
has mandated that CALTRANS give pipeline access along its freeway corridors to
reclamation entities with potential customers downline. Access will generally be at the
outside edges of freeway R.O.W., but occasion may arise when reclaimed water
pipelines will run down the center of the freeway corridor.
The City of Santee irrigates and maintains several landscaped medians of major street
such as Mast Boulevard, Carlton Hills Boulevard, Mission Gorge Road, and Town Center
Parkway. Although these areas are small, they can be easily irrigated with reclaimed
water if they are near a larger market or if a distribution pipeline runs within the roadway.
7.2.1.5 Parks and School Irrigation
Another significant market for reclaimed water is the irrigation of the many city and
county parks within the study area. The Santee Lakes Regional Park and Campground
currently uses Santee WRF effluent to partially meet its irrigation demand as well as for
lake replenishment which is discussed under Section 7.2.4 Recreational Use. The City of
Santee maintains several smaller parks throughout the City and has plans to irrigate
more of Mast Park and a new 46 acre park called Sports Area Park. The Undo Lake, El
Monte, and Flinn Spring County Parks have la~rge irrigation demands. Cactus County
Park will have about 5 acres irrigated in the future and two new County parks located off
Harbison Canyon Road and Tavern Road are proposed. Additional parks within the
County will be designated within future residential developments. The City of San Diego
has developed a master plan for the Mission Trails Regional Park. Although the park is
outside the PDMWD boundary, a portion of proposed activity areas is included as a
potential market.
Reclaimed water can also be used to irrigate school yards. Several school districts are
represented in the study area including the Santee, Lakeside Union, Grossmont Union
High, Alpine Union, and the Cajon Valley Union School Districts. The Grossmont
College is also located within the study area. Like the roadway medians, individual
schools have only small potential irrigation demands, but are easily identified and can be
included in the service area if near a larger market or distribution pipeline.
7.2.1.6 Residential Development Irrigation
Landscape irrigation within residential developments is a potential market for reclaimed
water in the developing areas. Reclaimed water can be used to irrigate common areas
7-12
PAGE 181 Show Image
in residential neighborhoods. Another beneficial use of reclaimed water would be to
irrigate fire breaks behind developments that border canyons, because brush-laden
slopes present a major fire hazard. Cut and fill slopes, development entrances,
neighborhood parks and schools, and landscaped medians within developments are
also potential use areas. By researching water records and landscape plans for
residential developments, it was found that these irrigated areas make up anywhere from
5 to 30 percent of the total acreage, with the majority falling in the range of 5 to 15
percent.
The best opportunity for this type of market are those developments in the planning or
conceptual stages. Reclaimed water facilities can be readily incorporated into these
future developments. For this study, it was assumed that no retrofifting of existing
residential developments would occur unless water records showed large uses for a
specific development. Developments that are currently under construction were
considered existing. Several developments are in the planning stages. Although
tentative maps are being processed, no specific irrigation or landscape plans were
available at the planning departments. For these areas, it was estimated that 10 percent
of the total acreage would be irrigated by 2000.
For the large undeveloped areas designated as residential use, it was assumed that 10
percent of the area that had slopes less than 25 percent had the potential to use
reclaimed water. Areas with slopes greater than 25 percent were considered
undevelopable. The undeveloped areas were divided into smaller areas according to
geographical features, water districts, planning area~s, and HSAs to facilitate sorting of
these markets in separate categories. The irrigation demand of these areas were
estimated for the ultimate reclamation system.
It should be noted that the City of Santee requires frontyard landscaping within
residential areas. The requirements include planting both a 5 gallon and a 15 gallon tree
specimen and installing an irrigation system. According to the City of Santee Planning
Department, it may be difficult to establish a frontyard maintenance district within single
family residential areas, unless a home owners association (HOA) already exists. The
Las Virgenes Municipal Water District (LVMWD) distributes reclaimed water to HOAs of
both multi-family and single family residences including aftached and detached units.
LVMWD customers currently using potable water for frontyard irrigation will have the
option to convert to reclaimed water when it is made available to them; however, if their
system is not converted, they will be purchasing potable water at 150 percent of the
current rate. According to the San Diego County Department of Health Services, the use
of reclaimed water for frontyard irrigation would be considered on a case-by-case basis
for each proposed project and would depend on several factors. These factors include
reclaimed water quality and the potential of cross connections by homeowners.
Although this use is potential, it was not considered a probable reclaimed market in this
study for purposes of estimating a firm irrigation demand. This use should be
reevaluated when the Master Plan is updated.
7-13

7.2.1.7 Commercial/Industrial Development Irrigation
The potential reclaimed water markets categorized as COmmercial/industrial
developments include the Santee Town Center, Upper San Diego River Improvement
Project (USDRIP), Edgmore Senior Center/Hospital, Home of Guiding Hands, and the
commercial/industrial parks around Gillespie Field. The Santee Town Center
encompasses 706 acres of primarily undeveloped land planned for a variety of uses.
The large areas of parks, and landscaped medians and parkways provide a potential
reclaimed market demand within the Town Center. The Lakeside Community Plan
designates the USDRlP area for industrial uses with a small amount of commercial use.
Based on the landuse of the proposed four alternatives for the USDRIP area, it was
estimated that 50 acres could be considered a potential reclaimed water market for the
ultimate project. A short term irrigation demand that could be served with reclaimed
water is the revegetation that is planned for the USDRlP area.
7.2.2Industrial Uses
Industrial use of reclaimed water remains an undeveloped market in San Diego County.
However, this market provides a use for reclaimed water that does not vary seasonally
and therefore is a good candidate for reclaimed water use. Reclaimed water use for
industrial processes will however depend on the water quality needs of the industry.
Three potential industrial markets were identified which include Woodward Sand and
Gravel, Nelson Sloan Sand Plant, and Precast Concrete. Sand and gravel quarrying
operations use a closed-loop washwater system with a water make-up requirement.
Reclaimed water could be used by these companies in aggregate-washing operations,
batch concrete mixing, and dust control.
It is expected that the majority of the development planned for the industrial center
located in El Cajon near Gillespie Field will be relatively dry" industries which would not
require large amounts of water.
7.2.3Indoor Commercial Building Use
Relatively new potential markets for reclaimed water are the numerous existing or
proposed commercial buildings within the study area. These buildings, if dual plumbed
could utilize reclaimed water. It has been estimated by the Irvine Ranch Water District
(lRWD) that the toilets and urinals in a commercial building account for approximately 60
to 80 percent of the building's total daily water consumption. If dual water systems were
utilized, the reclaimed water for plumbing could be dyed (blue) to distinguish it from
potable Water. Also, on-going monitoring of water pressure and checks for cross-
connections would be required.
To estimate the potential reclaimed water demands for indoor commercial building use
for undeveloped areas, the following factors were used:
7-14
PAGE 183 Show Image
· Area of structures:
Commercial development: 15,000 square feet per acre (SF/AC) (39%)
Industrial development: 17,000 SF/AC (40%)
· Equivalent dwelling units (ED U)
1,800 SF of office and manufacturing structure = 1 EDU
5,000 SF of warehouse structures = 1 EDU
· Type of structures:
Commercial development = 50% office and manufacturing structure and
50% warehouse structures
Industrial development = 100% warehouse structures
· Total water use:
250 gallon per day (GPD)
· Potential reclaimed water use:
60% of total water use
Annual use based on 6 days per week
Neither the California Department of Health Services nor the San Diego County
Department of Health Services has approved the use of reclaimed water for indoor
commercial building use due to the many unanswered questions and potential of cross
connections. However, the use of reclaimed water within three buildings has been
approved on an experimental basis in the lRWD. The term of the experiment has not
been defined since potential problems may not appear for several years. Although not
considered a market at this time, the quantities presented in this study were estimated to
determine the magnitude of this use if it is approved in the future.
7.2.4Recreational Uses
As previously discussed, up to 1.0 MGD of effluent from the Santee WRF is discharged
to the oxidations ponds, and about 0.4 MGD flows by gravity eventually to the lakes at
the Santee Lakes Regional Park and Campgrounds. The lakes provide visitors
recreations opportunities including fishing and boating. The goal of the PDMWD is to
increase flow through the lakes which will result in better water quality by mixing and
flushing actions. PDMWD desires to discharge 2.0 MGD of reclaimed water to the lakes.
The balance of reclaimed water from the Santee WRF would be distributed to other
markets~as would the intercepted overflow of the lakes. The actual "recreational use" of
the reclaimed water would be to replenish the lakes to make up water lost due to
evaporation, consumptive use by plants along the perimeter of the lakes, and seepage.
Evaporation losses can be estimated by correlating pan evaporation data provided by
PDMWD and the surface area of the lakes; however, other losses are not as easily
estimated. Based on evaporation data for three years, a pan coefficient factor of 0.77,
and 67.2 acres of surface area, the estimated evaporation losses are 296 AF/YR or a
7~15
PAGE 184 Show Image
0.26 MGD annual average with a peak day loss of 0.43 MGD. To account for other
losses, it was assumed, as directed by PDMWD, that the lakes would have a total peak
day demand of 0.5 MGD. Like irrigation demands, these losses vary seasonally
according to climatic conditions. Evaporation losses in January and December are
about 3 percent of the annual loss as compared to 13 percent of the total losses
occurring during each of the three summer months.
7.2.5Ecological/Aesthetical Uses
Although not considered a direct potential reclaimed water market for this study, stream
enhancement and groundwater recharge are discussed here as a possible use of
reclaimed water.
7.2.5.1 Stream Enhancement
The portion of the San Diego River from the Santee Lakes to the ocean is approximately
17 miles long. Within this distance the river contains lacustrine, riparian, and estuarine
environments. Of particular concern are the lacustrine and estuarine habitat. According
to a Draft report on Stream Enhancement Potential, 1988 through 2015, prepared by the
Regional Board in February of 1988, reduced water movement in the ponded areas or
lacustrine environment contributes to extended water detention times, vertical
stratification, and potential for substantial nutrient cycling. In a riparian environment algal
growth can be continuously exported from the system, however in a lacustrine
environment, algae may settle out and become incorporated into the bottom sediments,
providing an auxiliary source of nutrients for algal growth in subsequent years. Provided,
however, that there is adequate nutrient removal and significant flow volume, the
Regional Board believes that reclaimed water discharges can~be expected to have a
positive effect on most lacustrine environments.
Similarly, estuarine habitats, such as that at the mouth of the San Diego River, are also
sensitive to nutrient loadings. Another concern is the effect on the saline conditions in
this habitat if a uniform, continuous freshwater flow is discharged through the estuary.
The Regional Board maintains that through effective management of the volume, timing
and location of the increased dry-season stream flows, a coastal wetland can benefit
from improved water circulation, and increased frequency and extent of tidal exchange,
a reduction of hypersaline conditions, and the creation of true estuarine conditions.
Small stream flows could be utilized to enhance both the germination and growth of
particular marsh vegetation, however large flows may have to be diverted.
In general, the Regional Board believes that stream discharge to the San Diego River has
great potential for both promoting the use of reclaimed water and in enhancing a
valuable riparian habitat. The Regional Board has reviewed the environmental report
prepared by the PDMWD's environmental consultant, Ball & Associates, for the
proposed 4 MGD expansion to the Santee WRF. The report defines the environmental
effects which can be expected to occur from a stream enhancement discharge of small
7.16
PAGE 185 Show Image
volumes and various treatment levels. Through appropriate wastewater treatment and
an effective stream enhancement management program, the Regional Board is expected
to allow the initiation of a year-round stream enhancement discharge to the San Diego
River. The Regional Board has also suggested that several natural canyons tributary to
the San Diego River~could also be enhanced with a stream discharge. Opata Canyon
Creek, within the Miramar Naval Air Station, and Shepard and Murphy Canyons in
Tierrasanta could be considered for stream enhancement. Expanded environmental
studies are being planned to evaluate the effects of a discharge of larger volumes to the
stream.
7.2.5.2 Groundwater Recharge
Reclaimed water from the Santee WRF could be transported into the Santee HSA to be
used as recharge water for the groundwater basin. The reclaimed water would be of
befter quality than the local groundwater in this basin. Groundwater recharge may
require initial pumping the groundwater out of the aquifer before replacing it with
reclaimed water. It is anticipated that this recharged groundwater could be used for
irrigation and the aquifer could be used for wet-season storage of reclaimed water.
Thorough environmental studies beyond the scope of this Master Plan will be required to
determine if the use of reclaimed water to improve the basin is feasible. Other
groundwater basins located in the eastern portion of the study area may also benefit
from reclaimed water recharge operations.
7.2.6Outdoor Firefighting
Another potential use of reclaimed water that may become feasible in the future is
utilizing reclaimed water for outdoor firefighting, which would require designing the
distribution system for fire flows. Although questions and concerns exist regarding
reliability and a high potential of misuse, reclaimed water use for outdoor firefighting is
being considered by the regulatory agencies. Though not considered a market for the
Master Plan, the potential to use reclaimed water for fire hydrants should be reevaluated
when the Master Plan is updated.

CHAPTER 2 - SECTION 10632 - iD
iD. (Recycled water) The projected use of recycled water within
the supplier's service area at the end of 5, 10, 15 and 20 years.
In 1990, the District commissioned engineering consultants, Dudek
and Associates to develop a Water Reclamation Master Plan. The
plan was adopted by the District's Board of Directors on January
1, 1991, Resolution 91-7.
It should be noted that since the time of the preparation of the
Water Reclamation Master Plan, the markets for the Phase I
Upgrade Project to the District's Santee Water Reclamation
Facility have been refined for demand levels and distribution
feasibility for 1997.
At the completion of upgraded facilities at the District's Santee
Water Reclamation Plant, the production of reclaimed water will
increase to 2 MGD. This will supply approximately 10% of the
daily water demands in the District.
The following are the current estimated projections for the
annual use of recycled water within the District's service area.
Year 1995 400 AF Current production with
use only at Santee bakes

Chapter 2 - Section 10632 - lE
lE. (Recycled water) A description of actions, including
financial incentives, which `nay be taken to encourage the use of
recycled water where fresh water is not necessary, and the
projected results of these actions in terms of acre-feet of
recycled water used per year.
The District adopted a Water Reclamation Ordinance on November
14, 1989 (Ordinance 89-13) . This Ordinance mandates the use of
recycled water, for appropriate and approved uses, when it is
available and delivered to the customer. See "Water Reclamation
Ordinance" in the Appendix.
The District adopted a rate schedule for the sale of reclaimed
water to customers on June 13, 1995 (Ordinance 95-5). Reclaimed
water was priced at 85% of the Standard I potable water price (in
the inclining block rate structure). This pricing structure was
designed to encourage adequate and appropriate use of reclaimed
water and to assist in offsetting any customer-incurred costs to
retrofit existing irrigation facilities, supply appropriate
signage, provide an on-site irrigation manager and any other
required measures. See "Reclaimed Water Rates" in the Appendix.
On May 2, 1995, the District's Board of Directors heard a
presentation on the financial aspects of the 2 MGD Upgrade
Project for the Santee Water Reclamation Plant. An analysis of
reclaimed water sales at various levels showed a financially
feasible project. See attached "Executive Summary, Water
Reclamation Phase I Project Analysis."
The District adopted a Reclaimed Water Customer Site Retrofit
Funding Policy on October 24, 1995. This policy established that
the District would reimburse current irrigation customers for
eligible retrofit costs. See attached "Reclaimed Customer Site
Retrofit Policy."

Executive Sunui~ary
Attached is the analysis of the Water Reclamation Phase I project. Staff has developed
five financial models to analyze effect of the major factors that are likely to change,
and to affect the project's finances.
The Models are:
Mode! 1 The base assumptions assuming sales of 1,018 AFY.
Model 2 - The base assumptions assuming sales of 650 AFY.
Model 3 - The base assumptions assuming sales of 750 AFY.
Model 4 - The base assumptions assuming sales of 650 AFY and assuming that the
District did not qualify for the State Water Reclamation Loan.
Model 5 - Water Reclamation Project without a Distribution System
The graph below presents the estimated savings for the project with models one
through four. It also presents the loss that would occur if the District does not
construct the Distribution system.

The current estimate of reclaimed water sales is 829 acre feet per year.
In addition to modeling the financial result of changing the major factors, this repon
discusses the impact of various other minor factors affecting the financial viability of
the project.
Staff is recommending that the Board authorize Staff to continue with the project.

RECLAIMED WATER EXPANSION PROJECT PHASE I
THE PROJECT
The project takes advantage of the District's unique circumstances in sanitation and
water reclamation operations. The District decided in the mid-sixties not to join the
San Diego Metropolitan Sewerage System, but instead to construct its own water
reclamation plant. The plant was constructed to process 4 miffion gallons of
wastewater per day (MGD) with provisions to expand to 8 MGD in the future. Santee
Lakes was constructed to make recreational use of the reclaimed water that was
produced. A distribution system was constructed to deliver reclaimed water to the
areas of Cariton Oaks and Giflespie Field. Excess reclaimed water was discharged into
the San Diego River.
After several years of successful operations there was an outbreak of mosquitoes in the
San Diego River area. The Santee Water Reclamation Plant was identified as a
contributor toward that problem and ordered by the County Health Department to
restrict its discharge into the river. The Plant operations were constrained by the
Health Department and later by the Regional Water Quality Control Board to 1 MGD
operating capacity.
Over the course of the years, the District has been active in pursuing permission to
increase Plant capacity. Mter several studies and the development of a Reclaimed
Water Master Plan, the feasibility of a phased expansion of the Reclamation Plant was
envisioned. The Phase I project was to take the existing plant and distribution system
and expand it to 2 MGD. The Phase I project will also prepare the plant to be
expanded to 4 MGD when an acceptable means is developed for selling or disposing
of the additional reclaimed water that is produced. All expansion beyond the current 2
MGD is dependent on the ability to dispose of the reclaimed water in an
environmentally acceptable way.
This project is comprised of the following elements:
· Rebuild the sewer pump station at Field Operations, and add odor controls.
· Replace the secondary treatment with a Bardenpho Process.
· Expand the distribution system.
· Retrofit existing potable water irrigation systems with reclaimed water services.
FINANCIAL FACT6Rs
The financial analysis of the Reclaimed Water Expansion Project Phase I is intended
prepared to determine the financial viability of the project based on a variety of factors
that can affect the project's profit or loss. There are three primary factors which have
major effects on the project feasibility. There are a number of otl~er factors which
have minor effects.
PAGE 200 Show Image
The three major factors are:
1. Reclaimed water sales
2. Cost and availability of potable water
3. Cost of wastewater treatment with the San Diego Metropolitan Sewerage
System
These factors have the following general effects.
As reclaimed water sales increase, the project's viability increases. The minimum
reclaimed water sales are estimated to be 600 acre feet per year. The maximum is
esttmated to be 1,018 acre feet per year. As sales increase between 600 and 1,018 acre
feet per year, profit from the project also increases.
As the cost of potable water increases, the project's viability increases. The
assumption used in the analysis is that reclaimed water will be sold at the same pnce
as potable water. The retail price is set equal to the standard I water rate. The
analysis does not address several options that are being discussed.
The options are:
Lower rates for customers who use a higher volume of water.
Lower rates for customers who retrofit their potable water systems.
Lower rates for customers who use reclaimed water.
As the cost of wastewater treatment with the San Diego Metropolitan Sewerage System
increases, the project's viability increases. The Phase I project will reduce the amount
of wastewater treated in the Metro system. The treatment cost at the Santee plant will
increase only marginally. The reduced cost of the Metro system offset by the marginal
cost increase at Santee is shown in the model as a benefit to the reclaimed water
system. The higher the Metro cost the more benefit there is to the reclaimed water
system.
Minor factors include:
· Qualification for the "Water Pollution Contiol" Revolving Fupd Loan
The revolving loan fund interest is half the state's interest cost of loans.
Half the interest is paid by the district, the other half is paid by Federal
Grants. The total of the payments on the State loan are estimated to be
$20,866,300. The total of the payments would have been $30,536,940 at
normal bond rates. The revolving fund loan will save the District
$9,670,640 over the next 25 years, or about $386,825 per year.
· Qualification for the "Water Reclamation" Revolving Fund Loan
This revolving fund loan is also at one half normal interest cost. The
reclamation loans h~ve more extensive regulations. The District
reclamation system may not qualify if the volume of reclaimed water
sales is not sufficient to justify the cost of the distribution system. One
of the models will address the impact of the loss of the reclamation loan.

The District has borrowed $5,000,000 to fund the initial design and
planning work for the Phase I project, The District will have to issue
Certificates of Participation (COP) to pay off the balance of the
$5,000,000 loan and pay for the portions of the project not funded by the
State Revolving Fund loan,
MWD's New Demand Charge
The Metropolitan Water District of Southern California has adopted a
charge for each additional acre foot of water delivered. The initial
amount of the new demand fee is $1,000 per acre foot. If the Water
Reclamation project reduces the demand for potable water by 650 to
1,018 acre feet per year, it will save the District $650,OO() to $l,()18,000
in new demand fees. (One time charge).
· MwD's Readiness to Serve Charge
The Metropolitan Water District of Southern California has adopted a
charge for being ready to serve. The amount of Readiness to Serve is $
31.00 per acre foot. The Phase I project will reduce the Readiness to
Serve by $ 31,558 per year.
· Impact of Reduced Potable Water Sales
SYSThM CHARGE All of the customers scheduled to use reclaimed
water at this time are currently using potable water for irrigation. They
are currently hooked up to the system and are paying system charges.
The revenue from the system charge and the costs that were being paid
for with the system charge will be transferred from potable water to the
reclaimed water system. When that is done, the costs of reading, billing,
and maintaining the meters, which are functions paid for through the
system charge, will be transferred from retail water to reclaimed water.
Since both revenue and costs are being transferred there will be no
financial impact to the district.
REDUCED WAThR SALES - Currently, the retail water operation sells
potable water at $ 150.00 per acre foot more than wholesale water costs.
With the expected volume of reclaimed water we will reduce the amount
of potable water sold, as reclaimed meters are transferred from the
potable water system to the water reclamation system.
This reduction in potable water sales will range from 650 acre feet to
1,000 acre feet per year. Based upon $ 150.00 per acre foot, the loss in
gross profit on potable water will range from $97,500 at 650.00 acre feet,
to a high of $ 152,700 acre feet at 1,018 acre feet per year of potable
water.
PAGE 202 Show Image
This loss in gross profit will be made up by gwwth of potable water
sales. Growth rates are currently estimated to be in the range of 1.8% per
year. The growth of the district will be about 336 acre feet a year.
Since the effect of the customers going on the reclaimed water system
will be felt over a two to three year period, the net effect of the
reclaimed water system will be to transfer the new growth in the retail
water system to the reclaimed water system, thereby leaving the gross
profit on potable water approximately the same as it is today.
FINANCIAL ANALYSiS
The financial analysis presents the water reclamation operation base model and
compares the effect of changes in the major variables. The models presented will be:
1. Base budget updated with revised METRO sewer costs with 1,018 acre
feet sales.
2. Reduced sales to 650 acre feet.
3. Reduced sales to 750 acre feet.
4. Reduced sales to 650 acre feet and assume the loss of the reclamation
loan.
5. Water Reclamation Project without a Distribution System
in each of the models, the amount of the Metropolitan Sewerage System savings will
be shared with the water reclamation operation only to the extent necessary to keep the
water reclamation operation solvent. This will show the profitability of the water
reclamation project as it reduces the cost of sewer operations and lowers sewer rates.
Also, when reclaimed water sales are varied the impact is shown in the water
reclamation model.

RECLAIMED WATER CUSTONER SITE
RETROFIT FUNDING POLICY
BACKGROUND
The District has been pursuing the implementation of an expanded water
reclamation program for several years. Key policy statements by the
Board of Directors are summarized in the following:
A. November 14, 1989, approved the ordinance (89-13) regarding
the mandatory use of reclaimed water.
B. 1991, approved a master plan for water reclamation.
C. Nay 10, 1995, established the policy that the District would
help customers with the necessary retrofits.
D. June 13, 1995, approved the final environmental impact
report on the proposed project.
E. June 13, 1995, established the rate for reclaimed water to
be 85% of the Standard I potable water rate.
F. August 8, 1995, approved the construction of the expansion
and modifications of the Water Reclamation Facility.
The general policy of the Board on the cost to customers for reclaimed
water has been that the District should provide reclaimed water
service without an increase in costs to the customers. The two key
factors in implementing this general policy are the rates charged for
the commodity, and the costs of retrof its of existing systems.
In order to utilize reclaimed water, existing irrigation customers
will need to make conversions or retrof its of their systems.
Irrigation systems which were constructed in the last 10 years or so
will be relatively straightforward to retrofit. Older systems will
reguire significant work to ensure that the irrigation system is
separated from the potable water system and capable of functioning as
intended. Typical retrofit work includes marking and identifying
fixtures and sprinkler heads, posting signs, and ensuring the
separation from the potable water system. To facilitate the
conversion, staff is preparing a set of guidelines for retrof its.
The cost impact of this work will vary, depending upon the age, size
of the site, and type of irrigation eguipment used. The extent of the
work is estimated to cost approximately $2000 per acre of land
converted.
Utilization of reclaimed water will reguire common types of essential
facilities for all services, such as furnishing or converting meters,
furnishing and installing backflow prevention devices and other
details completed at additional costs. The following items of work
2
OCT24 1995 6
PAGE 205 Show Image
details completed at additional costs. The following items of work
are anticipated:
1. Design for the retrof it.
2. Purchasing or converting a meter for reclaimed water use for
each customer.
3. Purchasing and installing signage.
4. Color coding all necessary system components.
5. Inspection by Padre Dam staff.
6. Preparation of other related documentation.
7. Review, inspection and approval by the County Department of
Health Services.
8. Installation of reclaimed water meter.
9. Furnishing backflow prevention device for the potable water
service, if the existing service does not have one.
The cost of the above listed items associated with the retrofit
directly benefit the District by allowing the use of reclaimed water.
V Therefore, it is recommended the District to fund these costs.
New land developments have been required to install specially marked
and colored piping for reclaimed water systems for several years as
part of the project approval process by the District. Developers have
been willing to do this under the uniform application of the
regulation so that all developments permitted after a certain date
would be subject to the same rules. Other customers have been
converting their facilities as part of their maintenance programs.
Therefore, there are various levels of need for retrofit among the
customers
Various methods have been used to fund retrofit programs in other
agencies. Irvine Ranch Water District loans funds to the customer,
and uses Metropolitan Water District Local Projects Program incentives
to repay the note. The City of San Diego intends to pay for customer
retrof its.
RETROFIT REBATE PROGRAM
The scope of the retrofit program is summarized in Table 1. The list
of sites is contained in Exhibit A. The sites with existing plumbing
for reclaimed water are not listed, although inspection by the San
Diego County Department of Health Services will be necessary prior to
connection.

SUMMARY OF SITES REQUIRING RTTROFITS
Customer Type No. of Sites Total Demand

Government Irrigation 5 43.8
Multifamily Irrigation 38 181.1
Parks 8 59.9
Roadway Irrigation 40 52.8
School Irrigation 8 79.8
The recommended method of funding customer retrof its is through a
direct payment of eligible costs. Eligible costs would be established
through a plan review process followed by a bidding process, or, if
the customer wished to perform his own work, eligible costs would be
from a standard price list maintained by the District.
The overall process would involve an inspection of the site, design of
the retrof its by staff, and discussion with the customer. The
customer would be responsible for constructing the facilities. The
District would inspect the construction to ensure compliance with
various regulations and standards. The work that would be eligible
would be those items of work listed above. Ineligi~le costs would be
work involved in upgrading or enhancing an irrigation system beyond
the general scope of meeting the codes for reclaimed water use.
FINANCIAL IMPACT
The estimated cost of retrofits is approximately $400,000. Staff has
been preparing an application to the State Department of Water
Resources for a Conservation Construction Loan to assist with the
retrofit program. There is no guarantee that a loan will be made
through this program. The amount being applied for is $500,ooo. The
loan could be received by early next calendar year.
Costs for the retrofit program have been included in the ~ost
estimates for the reclaimed water distribution system.

1. Do not provide any financial assistance for retrofits.
This would be contrary to the general policy stated earlier.
This policy would have several impacts on the operation of the
project in meeting the reclamation goals. While the elimination
of any loans would lessen the burden on staff to mange the array
of agreements necessary and track payments, there would be an
increased burden to convince customers to retrofit their
irrigation systems. The net effect would be a reduced customer
base and a longer time for reaching a financial break-even point.
2. Provide a rebate proportional to the amount of land
retrofitted to each customer needing retrof its.
This would not be tied to the actual cost incurred, and hence, in
some cases would be~ a gift of public funds with no associated
benefit,~and therefore is prohibited by law.
4. Provide loans to customers who may wish to finance
retrof its, to cover costs equal to the expense of the
retrofit.
This loan would be interest free and repaid through a rate
surcharge above the rate which has been established as 85 percent
of potable.

CHAPTER 2 - SECTION 10632 - iF
iF. (Recycled water) A plan for optimizing the use of recycled
water in the supplier's service area, including actions to
facilitate the installation of dual distribution systems and to
promote recirculating uses.
The District adopted a Water Reclamation Ordinance (Ordinance 89-
13) on November 14, 1989. This Ordinance mandates the use of
recycled water, for appropriate and approved uses, when it is
available and delivered to the customer. The Ordinance also
mandates the installation of dual piping systems for new
construction in areas that will be served by the present or
future expansion of the treatment capacity at the District's
water reclamation facility.
The District's Engineering Department reviews all applications
for new service. Separate irrigation meters for appropriate
properties are required to facilitate current or future reclaimed
water service to the property. See "Water Reclamation Ordinance"
in the Appendix.
In order to maintain the quality of wastewater generated in the
sewer service collection area so that it remains suitable for
reclamation by the District's water reclamation facility, the
District adopted an Industrial Waste Ordinance (Ordinance 93-13
on October 12, ~993.)
The purpose of this ordinance is to provide for the maximum
beneficial public use of the District's wastewater system through
adequate regulation of sewer use and industrial wastewater
discharge, to provide for equitable distribution of the
District's costs, and to provide procedures for complying with
wastewater discharge requirements placed upon the District by
other regulatory bodies.
In 1990, the District commissioned engineering consultants, Dudek
and Associates to develop a Water Reclamation Master Plan. The
plan was adopted by the District's Board of Directors on January
22, 1991, Resolution 91-7.
Included in Chapter 2, Section 10632, 1-C are several pages taken
from that plan which provide a detailed description of the
potential uses of recycled water, including, but not limited to,
agricultural irrigation, landscape irrigation, wildlife habitat
enhancement, wetlands, industrial reuse, groundwater recharge,
and other appropriate uses, and a determination with regard to
the technical and economic feasibility of serving those needs.
It should be noted that since the time of the preparation of the
Water Reclamation Master Plan, the markets for the Phase I
Upgrade Project to the District's Santee Water Reclamation
Facility have been refined for demand levels and distribution

feasibility for 1997.
At the completion of the upgraded facilities at the District's
Santee Water Reclamation Plant, the production of reclaimed water
will increase to 2 NGD. This will supply approximately 10% of
the daily water demands in the District.
The District has researched all existing markets in the service
area and proposes to serve all that are cost-effective.
PAGE 210 Show Image
CHAPTER 2 - SECTION 10632 - 2
2. (Management of additional water supplies) Exchanges or
transfer of water on a short-term or long-term basis.
The District shares an intertie (Connection #6) with a
neighboring provider, the Helix Water District, which owns a
9,000 acre feet storage reservoir and filtration plant. Through
arrangements with the County Water Authority, the District
utilizes this intertie on a daily basis. For emergencies, this
intertie can supply less than one-half of the District's normal
warm season demand, 24 million gallons per day. See Chapter 1,
E2.
The amount of water obtained from Connection #6 via Helix Water
District varies according to season. Generally, District
purchases of water are 2/3 from Connection #4 (County Water
Authority direct) and 1/3 from Connection #6.
In addition, the District is working with the City of San Diego
and the Helix Water District to obtain additional water supplies
on a short-term basis. The City of San Diego owns the San
Vicente and El Capitan Reservoirs which store water for the City
of San Diego and SD County Water Authority (who contracts for
storage with several of its member agencies.)
The District could obtain this water through its existing inter-
tie with the Helix Water District. The additional supplies would
be delivered to the Helix Water District either directly to the
R. M. bevy Plant or to the bake Jennings Reservoir.
Padre Dam Municipal Water District, the Helix Water District and
neighboring Otay Water District are discussing opportunities to
lease capacity in the San Vicente or El-Capitan Reservoirs.
These supplies would be used to meet an emergency water outage
for 10 days.
The San Diego County Water Authority has embarked on an Emergency
Storage Project which will provide 90,100 acre feet of regional
storage for the Authority's service area. The final draft
environmental impact statement/report was released in November
1995. This project would provide more flexibility for water
transfers and exchanges among member agencies of the Authority.
For additional details, please refer the 1995 Urban Water
Management Plan Update, San Diego County Water Authority.
State-wide water transfers have been planned as a partial
