1995 Urban Water Management Plan - VCW[) No.8
SECTION I: PLAN ADOPTION, PUBLIC PARTICIPATION, AND
PLANNING COORDINATION
I-i. PLAN ADOPTION
This report has been prepared in response to the Urban Water Management Planning Act
(Water Code), Water Code Sections 10610 through 10656, which were added by Statute
1983, Chapter 1009, and became effective on January 1, 1984, as amended by AB 2853 and
other amendments. The Act was known as Assembly Bill (AB) 797 while pending before
the Legislature. A copy of the Water Code is included as Appendix A.
The Urban Water Management Planning Act requires that all California urban suppliers
providing water to more than 3,000 customers or supplying more than 3,000 acre-feet per
year or both develop an Urban Water Management Plan with prescribed requirements and
file it with the State Department of Water Resources. The suppliers are also required to
review, amend, and refile the Plan at least once every five years.
Because Ventura County Waterworks District No.8 supplies 16,000 acre-feet of water
annually through approximately nineteen thousand metered connections, it is required to
submit this updated Plan.
The Board of Directors of the Ventura County Waterworks District No.8 (hereafter referred
to as VCWD No.8) prepared and adopted previous plans in 1985 and 1990. By resolution,
the voluntary Countywide Water Conservation Management Plan with a special supplement
for VCWD No.8 was adopted in November 1994.
This updated Plan is a stand-alone document which describes the plans of VCWD No.8.
It will not duplicate, but rather it will complement and supplement other county-wide and
city-wide programs and studies that are already in place. These include the Simi Valley
General Plan Update (adopted December 1993), the Ventura County Waterworks District
No.8 Water Master Plan Update (February 1986), the Ventura County Water Management
Plan Annual Report 1994-1995, and the Facilities Plan for Wastewater Reclamation in Simi
Valley (August 1992).
This document is a general planning guideline for both the continuation of existing
management programs and the implementation of new programs during the next five years.
The majority of the issues in this Plan concern water conservation measures.

1995 Urban Water Management Plan - VCWD No.8
SECTION I: PLAN ADOPTION, PUBLIC PARTICIPATION, AND
PLANNING COORDINATION (Cont'd.)
This Plan is not a rigid directive for continuing or implementing water management
measures. Rather, it is a flexible and changing document that is frequently reviewed to
ensure responsiveness to the changing needs of the community.
1-2. DEVELOPMENT PROCESS OF THE 1995 URBAN
WATER MANAGEMENT PLAN
1-2.1 Public Participation
VCWD No.8 has actively encouraged community participation in its Urban Water
Management Planning efforts since development of its first Plan in 1985. Prior to
adopting the Plan, VCWD No.8 made the Plan available for public inspection and
review. A public hearing for the 1995 Plan is scheduled for March25, 1996. Prior
to the hearing, notice of this hearing will be published within the jurisdiction of
VCWD No.8 pursuant to Section 6066 of the Government Code and will be posted
in the City Clerk's Office. A copy of the hearing notice is included as Appendix G.
1-2.2 1995 Urban Water Management Plan - Summary:
The Urban Water Management Planning Act (AB 797) requires that VCWD No.8
file an updated version of the 1990 Urban Water Management Plan. VCWD No. 81s
1995 Urban Water Management Plan was prepared in accordance with AB 797 as
amended by AB 2853. This bill requires urban water purveyors to submit a plan to
the State Department of Water Resources addressing water use projections,
conservation measures, wastewater reclamation, possible supply deficiencies, and
ability to exchange or transfer water with neighboring suppliers. As amended, the
Plan must also include a description of the steps which would be necessary to
implement any proposed actions in the Plan and the method which will be used to
evaluate the effectiveness of each conservation method implemented under the Plan.
1-3. PLANNING COORDINATION
VCWD No.8 is a constituent agency of the Calleguas Municipal Water District (CMWD).
CMWD is a wholesale importer of water from the Metropolitan Water District of Southern
California (MWD). In order to address the interest of other constituent agencies in the area,

1995 Urban Water Management Plan - VCWD No.8
SECTION 1: PLAN ADOPTION, PUBLIC PARTICIPATION, AND
PLANNING COORDINATION (Cont'd.)
VCWD No.8 coordinated the development of the Plan with Ventura County, CMWD and
MWD.
1-4. FORMAT OF THIS REPORT
The sections in this report correspond to the outline presented in the Water Code, specifically
Sections 10631, 10632, and 10633 (Appendix A).
The elements set forth in Section 10631 are required to be included in all plans. Those set
forth in Section 10632 are required to be included in all plans prepared by agencies that will
have a "need for expanded or additional water supplies.'t Section 10633 requires a
discussion of the impacts of implementing the alternative water management practices
discussed in Sections 10631 and 10632.
This section addresses the Plan adoption and development process for the Plan. This section
also summarizes the conclusions, action steps, methodology, and key assumptions made in
preparing this Plan.
Section II briefly describes the history of the VCWD No.8 service area. Section III
describes water use in the VCWD No.8 service area and identifies the water supplies
available. Sections IV describes VCWD No.8's current conservation measures, conservation
through pricing and rate structures, and accomplishments over the past five years in
achieving more efficient use of water. Section V discusses the fliture conservation program
outlining planned programs and programs not planned for implementation. Section VI
outlines the budget and implementation schedule for programs described in section V.
Finally, a water conservation program analysis using the "WaterPlan" program is
summarized in Section VII. The individual sections corresponding with the specific
provisions of the Act are noted below:

1-5 CONCLUSIONS AND ACTION STEPS
The Plan's main conclusions and action steps during the next five years are presented below.
The remainder of the Plan is structured so that the reader can logically gain more detail on
each of the individual Plan components by reading the appropriate sections.
1-5.1 Conclusions:
As evidenced by past accomplishments, VCW[) No.8 and the City of Simi Valley
recognize that water use efficiency is no longer simply a good idea, it is a necessity.
Because of the water supply conditions prevailing in Ventura County and in
California in general, the general welfare requires that water resources be put to their
maximum practical beneficial use and that conservation measures be applied with a
view toward reasonable and beneficial use.

1-5.2 Action Steps:
1. Regarding public education, continue (and expand where appropriate)
VCWI) No.8 programs that supplement those offered by CMWI) and the
Ventura County Water Conservation Program. Individual VCWD No.8
activities include, but are not limited to, cable television announcements,
mailing inserts, talks at schools, and restaurant water conservation cards.
2. Work directly with CMW[) to address the various water conservation issues
within VCWD No.8 and Ventura County. CMWD is actively pursuing
educational programs throughout its service area to encourage water
conservation. Education and conservation are key elements to ensure the
most economic water supply in the fliture.
3. Adopt water conservation measures to minimize the effects of a water supply
shortage on Simi Valley residents should it occur.
4. Analyze the recommendations made in the 1992 Facilities Plan for Waste-
water Reclamation in Simi Valley and implement those measures that are
appropriate.
5. Continue the existing water management activities particularly with regards
to the meter calibration and maintenance program. Accurate measurement
and billing encourages voluntary conservation by the consumers.
6. Conduct an update to the 1986 VCWD No.8 Water Master Plan. This
comprehensive document addresses many of the issues concerning water
management with regard to proper facilities use and improvements. This
update will ensure that the Plan stay responsive to the changing needs of the
community.

1-6 METHODOLOGY AND KEY ASSUMPTIONS
This Plan considers programs for implementation over the next five years. Further, it
presents a five year budget and schedule for implementation of these programs. Therefore,
the administrative costs developed herein are for a five year period only. The benefits of
implementing these programs, however, in many cases extend beyond the five year period.
The extended benefits for a twenty year period (if applicable) are included in the economic
analysis in this Plan.
A minimum twenty year profile is used to estimate population growth and water supply
outlook, as well as to incorporate the net benefits of programs that are implemented over the
next five years.
A computer software program called "WaterPlan" was used to analyze several water
conservation alternatives contained herein. This program, developed by Synergic Resources
Corporation, is endorsed by the California Urban Water Conservation Planning department.
This Plan makes extensive use of the costs and benefits already analyzed and contained in
the "WaterPlan" documentation. In some cases, the software default factors are updated if
better information is readily available. The majority of the assumptions are flilly
documented in Section VII.
Because this Plan is intended to be a free standing document, this Plan includes sections that
are copied from the "WaterPlan" software documentation. This will ensure that all
assumptions are properly documented in this Plan.

SECTION II: HISTORY, GROWTH AND CLIMATE
11-1. HISTORY AND GROWTH
VCWD No.8 was formed by the Ventura County Board of Supervisors during the 1960's in
order to provide water service to the Simi Valley area. The responsibility for administering
this unction was transferred to the City of Simi Valley from the County of Ventura on July
1, 1977. The District's boundaries include all of the incorporated areas of the City.
However, the District only serves a portion of the area's customers. The balance of the
community is serviced by a private water company, Southern California Water Company
(SCWC). Exhibit 11.1 depicts the service areas of SCWC and VCWD No. 8.
The Ventura County 1993 Urban Water Use Survey is included as Table 11.1 and provides
a summary of the areas and water purveyors within Ventura County. The 1993 water use
data represents the most current information available. Although VCWD No.8 is a legally
distinct unit of government from the City of Simi Valley, the City Council serves as its
governing body and has continuing responsibility for its operations and financial management.
As discussed in the 1986 Ventura County Waterworks District No.8 Water Master Plan
Update, the City of Simi Valley is located in the southeastern corner of Ventura County
adjacent to Los Angeles County. It is situated equidistant between the civic centers of the
City of Ventura and the City of Los Angeles. The City is located in a valley which is
approximately nine miles along its east-west axis and varies in width from one to three miles.
As discussed in the 1988 Simi Valley General Plan Update, Simi Valley experienced
continued steady growth in the residential, commercial, and industrial environments during
the 1980's. The 1993 General Plan Update indicated that the Simi Valley Growth Area,
depicted on Exhibit 11.2 had a population of approximately 104,700 persons during 1993.
The General Plan projected population is anticipated to increase to an ultimate population of
approximately 140,450 persons by the year 2015. These population estimates reflect a
reduction in past population estimates provided in the 1986 VCWD No.8 Water Master Plan.
The 1986 Water Master Plan projected an ultimate population of approximately 150,000
persons in the City of Simi Valley. The more recent General Plan estimate represents a 6%
reduction from the Water Master Plan projections which may have been the result of
aggressive expansion expectations.

1995 Urban Water Management Plan - VCWD No.8
SECTION II: HISTORY, GROWTH AND CLIMATE (Cont'd.)
Although there has been growth in both the commercial and industrial environments, the City
of Simi Valley remains a predominately family-oriented community. The valley floor is
beginning to realize fbll development with medium density residential development occupying
the greatest percentage of the area. A pattern of outward expansion into the surrounding
hillsides began around 1980 and is continuing to accommodate the increased residential
growth.
Growth in both the commercial and industrial environments has also created a diversity of
employment opportunities at all skill levels for the residents of the City. As a result, more
residents are finding acceptable employment within Simi Valley reducing the need to commute
outside the City. These trends are expected to continue.
Table 11.2 summarizes the annual per capita water use by areas within Ventura County for
1993. Per-capita water use is one of the best indicators for monitoring the success of water
conservation efforts in the urban sector. Countywide, per capita use has been dropping in
recent years. Average per capita use for all of the reporting areas has dropped from 0.22 acre-
feet per year (AFY) in 1990 to 0.18 AFY in 1993 (Equivalent to 196 gallons per capita per
day (gpcd) in 1990 and 161 gpcd in 1993). The per capita use within Simi Valley for 1993
is at 0.19 AFY or 170 gpcd. A summary of water use by areas within Ventura County over
recent years is shown on Table 11.3.
11-2 CLIMATE
Climatic conditions are characterized by meager rainfall, low humidity, high summer
temperatures, abundant sunshine, and relatively mild winters. The average temperature
throughout the year is 62SF. Precipitation occurs primarily during the winter months from
November through March with an annual mean rainfall between 13 and 15 inches.

SECTION HI: PAST, CURRENT AND PROJECTED
WATER USE AND SUPPLY
This chapter provides a summary of VCWD No.8's service area covering potable and non-potable
water use, population, and socioeconomic characteristics.
111-1. WATER SOURCES AND SUPPLY OUTLOOK
Both VCWD No.8 and the Southern California Water Company purchase their water
from the California Aqueduct System through CMWD. In the event service is disrupted
from the California Aqueduct System, facilities also exist to deliver Colorado River water.
In addition, over 30 million gallons of water are also kept in storage tanks within the Simi
Valley area for operational purposes, fire protection, and emergency services. Finally,
Bard Reservoir, which has a total storage capacity of ten thousand acre-feet of water, is
also intended to be an emergency supply for this area.
For non-potable water uses, VCWD No.8 owns two wells in the Tapo Canyon area.
These two wells can be used in an emergency for blending with CMWD water as a
backup source of potable water. Chemical treatment for well water is readily available
should the need arise. The above water sources are identified in Exhibit 111.1.
The use of reclaimed water as a potential fliture supply source is currently under
consideration by VCWD No.8. The City of Simi Valley's Sanitation Division completed
its Wastewater Reclamation Facilities Plan Update in 1992. The plan outlined a water
reclamation program which includes the construction of a reclaimed water distribution
system to serve the City of Simi Valley. The project would reclaim approximately 4.2
MGD (4,618 AFY) of tertiary effluent from the Simi Valley Water Quality Control Plant
(SVWQCP).
VCWI) No.8 has entered into an agreement with CMWD to develop a pilot reclaimed
water project for the local landfill. This pilot project may be the prelude to a flill scale
project similar to that presented in the 1992 Wastewater Reclamation Plan.
The 1986 Water Master Plan Update forecasted a gradual population increase for Simi
Valley throughout the 1990's and into the twenty-first century. A graph showing the
historical and projected population through the year 2015 is included as Exhibit 111.2. As
indicated on the graph, actual population increase has been at a lower rate than projected

in the Water Master Plan. The 1993 updated Simi Valley General Plan estimated the
ultimate Simi Valley population to be approximately 6% lower than predicted in the
Water Master Plan. For the purposes of this report, it was assumed that the projected
water demands will follow the population trend indicated in the Water Master plan. It is
estimated that the average daily water demand by ultimate development in 2015 will be
33.4 million gallons per day (MGD) or 37,425 acre-feet per year. The maximum daily
demand will be approximately 1.8 times the average daily water demand. These
projections include both the VCWD No.8 and the Southern California Water Company
service areas. Presently, VCWD No.8 supplies approximately 65% of the daily water
demand within the Simi Valley area and the Southern California Water Company supplies
the remaining 35 percent. A graph showing the average day water demand projections
through 2015 is included as Exhibit 111.3.
111-2. USE AND SUPPLY
Fluctuations in water demand (i.e. average daily demand versus maximum daily "peak"
demand) are important factors in the determination of production, storage, and distribution
system requirements. The VCWD No.8 system is designed to handle these fluctuations,
and as part of the 1986 Water Master Plan Update it is being expanded through a planned
phased program to meet the projected new demands over time. In addition to meeting the
"peak" demand requirements, the system is designed to handle the annual cyclic
fluctuations; an example being that water use during the summer is greater than water use
during the winter.
Future water supply will continue to be provided by CMWI). However, should CMWD
have its water supply reduced by MWD, then CMWD would also cut back its supply to
all of its customers, including VCWI) No.8.

SECTION IV: CURRENT WATER CONSERVATION
IV-1 WATER MANAGEMENT ACCOMPLISHMENTS DURING LAST FIVE YEARS
(COMPARISON TO 1990 PLAN)
As part of the 1988 Simi Valley General Plan Update, several policies and goals were
enacted concerning proper water management. One policy, expressed below, best sums
up all of the items concerning water management:
"POLICY IV-1 .7: The City shall promote water conservation and shall take all necessary
steps to ensure that water quality and quantity are adequate for safe, efficient use."
With this goal in mind, Simi Valley and VCWD No.8 have accomplished a wide variety
of items during the past five years directed in this area. The 1986 Ventura County
Waterworks District No.8 Water Master Plan Update provided a foundation for the various
facilities improvement programs over the past few years (and forecast into the fliture). The
City of Simi Valley's Sanitation Division updated its wastewater reclamation facilities plan
in 1992. This update will provide the stimulus for additional conservation efforts in the
fliture.
VCWD No. 8 has maintained membership in the Ventura County Water Conservation
Program. This group is actively pursuing public information and educational programs
throughout Ventura County to encourage water conservation.
Regarding conservation education, VCWD No.8 is working closely with CMWD to
address water conservation throughout their service areas. By working with CMWD,
VCWD No.8 will ensure that conservation awareness efforts are undertaken on a
consistent basis not only within Simi Valley, but also throughout Ventura County.
Detailed descriptions of the water conservation measures employed by CMWD can be
found in the CMWD 1995 Urban Water Management Plan.
VCWD No.8 has also undertaken a variety of education and other programs on its own.
These are briefly summarized as follows:

PAGE 29 Show Image
1995 Urban Water Management Plan - VCWD No.8
SECTION IV: CURRENT WATER CONSERVATION (Cont'd.)
* Cable Television Public Service Announcements:
In response to past drought conditions, a series of water conservation tips were
displayed on the local community cable channel in order to provide customers with
techniques to reduce overall water use. Cable announcements will be provided to
customers again if fliture drought conditions occur.
* Mailing Inserts:
A water conservation brochure is available on request. A copy of this brochure is
included as Appendix C for reference.
* Talks at schools:
In past years, District personnel have given several water conservation talks to both
junior high schools and Moorpark College classes. These talks are given by request.
* Restaurant Water Conservation Cards:
Restaurant "water by request only" cards are available for any interested restaurants.
Further, the activities discussed below were mentioned in the original water management
plan adopted in December 1985. Their current status is summarized below:
1. Meter Calibration and Maintenance:
VCWD No.8 recognizes that if not properly maintained and calibrated, water
meters can have slippage resulting in the customers seeing artificially low usage and
billing. For this reason, VCWD No.8 maintains an active program where meters
(2" and larger) are regularly field tested and repaired/replaced (if necessary). This
ensures that the user is aware of the actual usage and cost. If slippage has been
occurring in the meter, once the meter is repaired, the user will be faced with higher
bills, and will develop internal programs to encourage conservation.
As a result of this program, the VCWD No.8 has seen a decrease in the amount of
unaccountable water since the programs inception. This program was started in
1986.

SECTION Iv: CURRENT WATER CONSERVATION (Cont'd.)
2. Landscape Review Guidelines:
The City's Department of Environmental Services, and the Building and Safety
Division have developed guidelines for water saving landscape for new
construction. Pamphlets are available if customers request them concerning
landscaping and other conservation ideas. These pamphlets have been available for
approximately five years. VCWD No.8 has also recently adopted a landscape
ordinance and developed a landscape maintenance manual outlining required
irrigation methods for new construction.
3. Standard Development Conditions:
The City's Department of Environmental Services, and the Building and Safety
Division have developed guidelines for water saving landscape, and low flow toilets
for new construction. Ordinance No.731 which mandates the use of certain water
conservation devices was also adopted in June 1990. A copy of this ordinance is
included as Appendix B for reference.
4. Increasing Block Rate Structure:
VCWD No.8 maintains a two-tiered rate schedule for residential 5/8" through 1
metered service. This serves to promote water conservation by discouraging
excessive water use.
From zero through fifty-five billing units (one billing unit equals 100 cubic feet) per
standard billing cycle, the rate is $1.25 per billing unit. In excess thereof, the rate
increases to $1.58 per billing unit. (The standard billing cycle varies from 56 to 64
days.)
VCWD No.8 is continuously reviewing current rate structures in response to any
planned changes in delivery quantities by CMW[) and to flirther promote water
conservation. A summary of the 1995 bi-monthly residential water rates for VCWD
No.8 and various neighboring agencies is included as Table IV. 1.
5. Water Meters During Project Consfruction:
To encourage water conservation during project construction, VCWD No.8 requires
that all construction water be metered unless otherwise approved due to special

circumstances. Billing for both metered and unmetered construction water is based
on usage.
6. Individual Meters (Condominiums, etc):
Individual meters are required for all new construction unless proven impractical.
Although an active retrofit encouragement program is not being pursued at this time,
it remains a filture possibility as changing situations dictate.
7. Water Conservation Program:
As discussed above, VCWD No.8 works directly with the CMWD to address
conservation. This partnership will ensure that fliture conservation efforts will be
undertaken on a consistent basis not only within Simi Valley but throughout
Ventura County.
8. Previous Water Usage on Water Bills:
This program was implemented in fiscal year 1986/1987. Water usage for both the
current billing period, and the billing period one year before, is now indicated on
each customer's water bill.
9. Leak Detection Program:
VCWI) No.8 has purchased line locators and a "Bigfoot" leak detection device to
pinpoint water leaks. A formal leakage control survey was conducted for VCWD
No.8 in October, 1994. Approximately 211 miles of main lines were inspected
resulting in a total 32 leak indications. Each leak detected during this survey was
repaired.
Currently, detection of main lines are done on an "as-needed" basis as observed.
The "customer alarm" system seems to work quite well within Simi Valley. Water
leaks (due to line ruptures, sprinkler system failures, etc.) are reported quickly by
the public when they occur. This is probably due to a heightened water
conservation awareness throughout Southem Califomia due to the extreme drought
situations which have occurred in the past. Once the leak is reported, the leak
detection equipment is then used to pinpoint the source of the leak prior to
excavation and repair. The use of this equipment is resulting in more rapid leak

location and shorter system downtime, all of which lead to beffer system
management.
VCWD No.8 now conducts a complete leak detection survey of its entire water
distribution system every five years.
10. Systemwide Water Audits:
VCWD No.8 has implemented a number of measures to allow more accurate
monitoring of water deliveries and reduce the percentage of unaccountable water.
These measures are summarized below:
* VCWD NO.8 has been phasing in the installation of pump station master
meters for each pressure zone. Total installation is now approximately 100%
complete.
* VCWD No.8 has implemented a meter change-out program for 3/4" and 1"
water meters that are 20 years old. This program is aimed primarily at
residential meters. During the past ten years approximately 16,000 meters (out
of 18,000 meters) have been replaced to ensure their accuracy.
* An improved computerized billing system was implemented during the 1986
time frame, and hand-held computerized data collection devices were
implemented during 1989. The use of this improved computerized system
continues today and this automation allows more frequent analysis of the delivery
data.
All of the above measures improve the ability to audit and account for all water
deliveries. It should be noted that VCWD No.8 has a relatively new system where
the majority of the pipelines are less than thirty years old. In addition, the majority
of pipeline is made of highly corrosion resistant materials, such as concrete, which
minimizes system leaks.

1995 Urban Water Management Plan - VCWD No.8
SECTION V: EXPANSION OF CONSERVATION PROGRAM
This section describes the water management programs which are proposed to be continued or
implemented over the next five years and those programs which were selected to be discontinued
at this time. An analysis of the various water conservation measures using the "WaterPlan" software
is also summarized.
V-i WATER MANAGEMENT PROGRAMS DURING NEXT FIVE YEARS:
The following programs will be continued or implemented during the next five years:
1. Regarding public education, continue and expand VCWD No.8 programs that
supplement those offered by CMW[) and the Ventura County Water Conservation
Program. Individual VCWD No.8 activities include, but are not limited to, cable
television announcements, mailing inserts, talks at schools, and restaurant water
conservation cards.
2. Work directly with CMWD in coordinating conservation efforts with other
neighboring agencies. VCWD No.8 will continue to provide public information and
perform educational programs to encourage water conservation on a request basis.
3. Continue the existing water management activities as discussed in Section IV,
particularly with regards to the meter calibration and maintenance program.
Accurate measurement and billing encourages voluntary conservation by the
consumers.
4. Evaluate the District's hydraulic model and evaluate the need to update the 1986
Water Master Plan. This comprehensive document addresses many of the issues
concerning water management with regard to proper facilities use and
improvements. This update will ensure that the plan stays responsive to the
changing needs of the community.
5. During droughts, set-up accounting mechanisms to track the costs of water
conservation activities. This will increase the awareness of water conservation
during the budget process and ensure the conservation activities are reviewed and
monitored appropriately.

1995 Urban Water Management Plan - VCWI) No.8
SECTION V: EXPANSION OF CONSERVATION PROGRAM (Cont'd.)
V- 2. WATER MANAGEMENT PROGRAMS NOT SELECTED FOR
IMPLEMENTATION DURING NEXT FIVE YEARS:
1. Short- and Long-term Water Exchanges or Transfers:
Due to the lack of any feeder lines from surrounding areas, the use of short- and
long-term water exchanges is not considered practical or economic at this time. All
of the VCWD No.8 water is imported via CMWD, which in turn obtains its water
from MWD. Water is treated at the Jensen Water Treatment Plant in the San
Fernando Valley prior to conveyance to the service area.
As previously illustrated in Exhibit 111.1 of Section III, CMWD supply begins at the
Santa Susanna Tunnel. The tunnel conduit branches off into two feeders which
traverse the Simi Valley area. A 48" to 51" diameter feeder services the southern
boundary of the Valley, and a 66" to 78" diameter feeder transverses the area along
Cochran Street. No other major feeder lines are in place.
2. Incentives to Alter Water Use Practices:
In the context of this plan, incentives to alter water use practices mean a situation
where the customer reimburses VCWD No.8 for the cost of purchasing, supplying,
and/or installing a water conservation device. Incentives in this context do not
include discrete incentives such as variations of the rate structure to encourage
conservation (which are already in-place).
At this time, due to a combination of the administrative overheads involved and the
general climate within the community, the implementation of such incentives is not
considered practical. However, with financial assistance from other agencies, such
as CMWD and/or MWD, these types of programs may be feasible and considered
for implementation.
V-3 "WATERPLAN" ANALYSIS
In addition to the items discussed above, several other water conservation measures were
analyzed using the "WaterPlan" sofiware. These measures, along with their internal rates
of return, are summarized below. The "WaterPlan" analysis does not consider financial

SECHON V: EXPANSION OF CONSERVATION PROGRAM (Cont'd.)
assistance from any other agency. Under this analysis, it is assumed VCWD No.8 is the
sole source of program flinding. Refer to Section VII for the complete details on each of
these plans.
MEASURE ANALYZED I.R.R.
A. Minimum Kit Delivery Program Negative %
B. Residential Water Audit -10.9 %
C. Ultra-Low Flush Toilet Replacement -4.7%
D. Residential Lawn Watering Guides Negative %
E. Seasonal Rates (Residential) Negative %
Due to the low internal rates of return (from the VCWD No. 8 perspective),
implementation of these additional measures will not be pursued at this time. Financial
assistance from outside agencies such as CMWD, MWD, State of California, or federal
EPA could increase the rates of return and make any of these programs financially feasible.
These measures will be evaluated again when changing situations dictate.
The internal rate of return (I.R.R.) is one of four common indicators that are used to
evaluate investments. The other common indicators are the net present value, the
benefit/cost ratio, and the payback period. Because the internal rate of return is typically
accepted as the best indicator, it is the only one discussed here.
The internal rate of return is the discount rate where the present value of the benefits equals
the present value of the costs. An investment is considered to be cost effective if the
internal rate of return is greater than a predetermined "hurdle" discount rate. For example,
if an investor desires a minimum 10% return on his investment (his "hurdle" rate), but the
projected internal rate of return is 6%, then the investor will not invest. If; however, the
desired return remains at 10% and the projected internal rate of return is 11%, then the
investor will invest.
The projected internal rates of return for various activities are listed above. For many
public water agencies, a desired minimum "hurdle" rate is around 10%. Because the
projected internal rates of return for the activities above are well below this "hurdle" rate,
they will not be flirther evaluated at this time. The internal rates of return for options A,

D and E are highly negative (beyond the capability of the software to calculate). Refer to
Section VII for the details on the economic analyses performed.
VA WATER SHORTAGE CONTINGENCY PLAN SUMMARY
A Water Shortage Contingency Plan (WSCP) is a requirement of Section 10620 of the
Water Code for all California urban suppliers supplying more than 3,000 AFY or providing
water to more than 3,000 customers. In March, 1992, VCWD No.8 completed an update
of its WSCP which served as the primary plan to mitigate the numerous potential adverse
impacts associated with a water shortage emergency. The WSCP eliminated the Urban
Water Management Plan's previously required section on source deficiencies. Therefore,
the WSCP complements the Urban Water Management Plan and serves to consolidate and
formalize all past and present planning efforts.
Required topics that are addressed in the WSCP include:
* Coordinate planning efforts with local and regional agencies.
* Estimate the worst case water supply available during the next 12, 24, and 26
months.
* Predict water demand during the next 12, 24, and 26 months, including growth by
customer category.
* Determine action stages to be undertaken in response to supply shortages up to 50
percent.
* Determine trigger points for each specific action stage.
* Establish consumption limits.
* Establish enforcement methods.
* Adopt no-waste ordinances.

1995 Urban Water Management Plan - VCWI) No.8
SECHON V: EXPANSION OF CONSERVATION PROGRAM (Cont'£L)
Provide revenue impact mitigating measures.
The following is a summary of the programs implemented through the 1992 Contingency
Plan.
Coordinate Planning Efforts: Calleguas Municipal Water District (CMWD) is the
wholesale water agency for Ventura County. Since VCWD No.8 relies exclusively
on imported water from CMWD, all shortage contingencies were coordinated and
based upon CMWD's plan. CMWD adopted the provisions of MWD's Incremental
Interruptible Conservation Plan (`ICP) which was, in turn, adopted by VCWD No.
8.
* Estimate Worst Case Supply: Worst case supply estimates were based on the
assumption that there would be a 50 percent reduction in CMWD sources. The
Stage VI provisions of the IICP mitigate this condition. A 50 percent reduction in
CMWD supplies would mean VCWD No.8 would only receive 12,580 AFY from
CMWD, down from the base year (1989-90) amount of 18,100 AFY.
* Projected Water Demands: Demands expected during the next 36 months,
including three percent growth and considering Stage VI reductions, would be met.
Adjustments to the Water Conservation Inflection Point (WCIP) would possibly be
required to offset supply deficiencies. This would not be a significant amount for
current water use reduction goals.
* Determine Action Stages: VCWD No.8, being almost totally dependent of
CMWD as a supply source, utilizes the action steps mandated by the IICP. VCWD
No.8 modifies its water rates accordingly, depending on the reduction goal. These
economic incentives have proven extremely successfiil by meeting or exceeding
annual conservation goals.
* Determine Trigger Points: Trigger points listed in the IICP are used by CMWD.
Upon modification by CMWD, VCWD No.8 implements deductions usually
through a modification in the District's water rate structure as described above.

PAGE 48 Show Image
1995 Urban Water Management Plan - VCWD No.8
SECHON V: EXPANSION OF CONSERVATION PROGRAM (Cont'd.)
Establish Consumption Limits: VCWD No.8 has established consumption limits
for single-family residential use based upon historical per-household use. All other
uses, non-SFR, are based on a straight reduction from past billing history. SFR
limits are reflected in the District's water rate structure. For example, the allocation
for SFR use (to meet CMWD Stage V goals) is 44 Hundred Cubic Feet (HCF) per
Standard Billing Cycle (SBC), per connection. SFR users exceeding 44 HFC
(called the Water Conservation Inflection Point or WCIP) are billed at a
substantially higher rate, which is called the Water Conservation Factor (WCF).
Similar WCF's are imposed for non-complying non-SFR users.
* Established Enforcement Methods: The economic incentives have proven highly
successfiil in VCWD No.8 achieving its conservation goals. Punitive ordinances
against water waste have been adopted, but have not been needed in the past.
* Provide Revenue Impact Mitigating Measures: VCWD No.8 utilizes a water rate
structure that ensures all overhead, operating and manhour costs are covered by a
minimal base charge. The cost of water is paid through the commodity charges.
Pumping costs are assessed based upon each customer's zone. Because of this rate
structure, District revenues are not affected by reductions in the water consumption.

Notes:
1. The "WaterPlan" software makes a distjnction between PLANS and PROGRAMS. A PLAN consists of one
or more individual PROGRAMS. For example, a kit delivery program and an educational program might
combine to form one plan. In "WaterPlan" the administrative costs are only reflected in the plan line, i.e.
they are not included in the detail reports for each program. In the example above, the difference between
the present value of the plan and the present value of the program is an indication of the administrative costs
for the program. (Administrative costs are entered into "WaterPlan" as real costs per year (net of inflation) in
1995 dollars in the year they occur.)
2. The "WaterPlan" sofrware calculates benefit/cost analyses from three perspectives: society, agency, and
participant. This is because the impact on each group may differ, with some groups being made better off
from the program while other groups are made worse off. A table listing the costs and benefits assumptions
by perspective is included elsewhere in these appendices.
3. Present Values are automatically calculated by "WaterPlan" using various internal discount factors and
discussed elsewhere in these examples.
4. The total water savings above are over the life of plan and program(s). This information is automatically
calculated by "WaterPlan" based on prior studies that were done as documented in the "WaterPlan"
information.
5. Benefit/Cost Ratio = ~et Present Value + Present Value of Total Cost)/(Present Value of Total Cost).
6. Net Present Value (NPV) = PV of Total Benefits - PV of Total Costs, PV of Total Benefits =PV of Total
Cost * Benefit/Cost Ratio.
7. Payback Period is the number of years to recover the initial investment. This method does not account for
the time value of money and excludes the impact of costs and benefits that occur after the end of the payback
period.
8. The Internal Rate of Return (IRR) is the discount rate where the present value of the benefits is equal to the
present value of the costs. At this rate, the Benefit/Cost ratio equals 1.

Notes:
1. For VCWD No.8, the year designated above shall be the start date of the fiscal year. For example, for the
fiscal year starting July 1, 1995 and ending June 30, 1996, the year indicated shall be known as 1995.
2. The Agency Direct Costs include any applicable initial capital costs, installation costs, annual O&M, and
administrative overhead. With the exception of the administrative costs, the majority of the other costs are
automatically generated by the "WaterPlan" software. The administrative costs are the sum total of the
administrative costs associated with each program. The Agency Directs Costs also equal the Costs to
Society minus the costs to the participants.
3. An estimate of the foregone revenues to the agency based on the water savmgs and the rates.
4. Total Costs to Agency = Agency Direct Costs + Foregone Revenue.
5. The total water savings for the plan (and associated program(s)) by year. This information is automatically
calculated by "WaterPlan" based on prior studies that were done as documented in the "WaterPlan"
information.
