A. Purpose of Report
CHAPTER I
INTRODUCTION
This Report has been prepared responsive to the mandates contained within
the Urban Water Management Act (Act), Water Code Sections 10610 through
10656 which were added by Statutes 1983, Chapter 1009, and became
effective on January 11, 1984 .
Known as AB797 while pending before the Legislature, the Act essentially
provides that any urban water supplier providing water for municipal
purposes to more than 3,000 customers or supplying more than 3,000 acre
feet of water annually shall prepare and adopt, not later than
December 31, 1985, an urban water management plan. This Report is,
therefore, the formal document to satisfy the requirements of the Act. A
copy of the Act is included as Appendix "A" .
B. Preparation and Adoption of Report
This Report was prepared by the staff of the San Diego County Water
Authority for the Costa Real Municipal Water District .
A Public Hearing, conducted by Costa Real Municipal Water District, was
held on December 11, 1985 at 5950 El Camino Real, Carlsbad, for the
purpose of obtaining public comment and input on the draft Report.
This Final Report was adopted by the Board of Directors of the Costa Real
Municipal Water District on December 11, 1985 by Resolution 483 (see
Appendix "B") .
c. Format of Re£ort
The chapters in this Report correspond to the outline presented in the
Act, specifically Sections 10631, 10632 and 10633 .

C. Format of ReEort (cont,)
The first four chapters following this Introduction discuss past, current
and projected water demands; current water conservation; alternate water
conservation measures; and water supply deficiencies .
The last chapter discusses future water management practices which could
supply additional water or reduce water demands. The discussions cover
waste water reclamation, water exchanges or transfers, management of water
system pressures and peak demands, incentives to alter water use
practices, public information and educational programs, and changes in
pricing, rate structures and regulations. The chapter also contains an
evaluation of the preceding six water management practices categories from
economic, environmental, social, health, customer impact and technological
standpoints .

CHAPTER II
GENERAL INFORMATION AND PAST, CURRENT, AND PROJECTED WATER USE
A. The Costa Real Munici£al Water District
1. Basic Data
The Costa Real Municipal Water District (District) was formed in 1954
pursuant to Section 71000 et. seq. of the California Water Code. The
District joined the San Diego County Water Authority (Authority) and
the Metropolitan Water District of Southern California (MWD) the same
year to acquire the right to purchase and distribute imported water
throughout its service area .
The District covers an area of 31.8 square miles as shown on Figure 1
of which about 86 percent is currently receiving water service.
Through an agreement with the City of Carlsbad, the District is
responsible for the operation and maintenance of all potable water
supply and distribution facilities except the actual water meters
within its boundaries. All water delivered by District facilities is
purchased at a uniform rate by the City of Carlsbad. The City, in
turn, maintains all water meters and bills all customers at a uniform
rate on a monthly basis. Although the District area is experiencing
rapid urbanization due to the growth of Carlsbad, much rural land area
remains. Agricultural water demands account for about one-third of
the annual District water sales .
The population within the District's boundaries was 30,200 in 1980.
Based on projections by the San Diego Association of Governments (See
Appendix C), the population is expected to increase sharply to 59,300
in 1990 and 86,800 by the year 2000 .
All water delivered by the District is filtered, imported water
purchased from the Authority. The District has neither major storage
nor water treatment facilities. Use of local groundwater to
supplement the imported water supply was terminated in the early
1950's as these local supplies became highly mineralized.

Wastewater collection, transmission, treatment and disposal or
reclamation services to developed areas within the District boundaries
are provided by other agencies not associated with the District .
2. Relationship to Other Water Agencies
The District is one of twenty-four member agencies of the San Diego
County Water Authority (Authority). Member agency status entitles the
District to directly purchase water for its needs from the Authority
on a wholesale basis, and the District looks to the Authority to
insure, to the best of its ability, that adequate amounts of water
will be available to satisfy future water requirements. A map of the
Authority which also shows the position of the District within the
Authority boundaries is included as Figure 2 .
B. The San Diego County Water Authority
The San Diego County Water Authority (Authority) was organized on
June 9, 1944 under the County Water Authority Act for the express purpose
of importing Colorado River Water into San Diego County .
The imported water, now a combination of Colorado River Water and State
Project Water, is sold wholesale to the 24 member agencies of the
Authority, The member agencies are autonomous and their city councils or
boards of directors set local policies and water pricing structures. Each
member agency may appoint at least one representative (based on assessed
valuation) to the Board of Directors of the Authority .
All water distributed by the Authority is purchased from the Metropolitan
Water District of Southern California (MWD) and is delivered into
Authority pipelines from Metropolitan facilities located just south of the
San Diego County/Riverside County line as shown on Figure 2. The
Authority annexed to MWD in 1946 and is now represented on the MWD Board
by six Directors. The Authority is the largest of the 27 member agencies
of MWD and currently purchases approximately 30 percent of the total MWD
water supply .

C. The Metro£olitan Water District of Southern California
The Metropolitan Water District of Southern California (MWD) was created
by a vote of the people in 1928 following the passage of the Metropolitan
Water District Act by the California Legislature to provide supplemental
water for cities and communities on the south coastal plain of California.
Since its formation, MWD has grown to include 27 member agencies
(including the San Diego County Water Authority), as shown on Figure 3,
and currently covers an area which includes portions or all of Ventura,
Los Angeles, Orange, Riverside, San Bernardino and San Diego Counties.
Acting as a water wholesaler and providing waters from both the Colorado
River and Northern California, MWD supplies almost half of the more than 3
million acre-feet a year used by the nearly 13 million people within its
service area .
D. Historic Water Use Within the Costa Real MWD
Table 1 lists the District's water sources and amount of sales by year for
the period Fiscal Year 1969-70 through Fiscal Year 1983-84. Available
records differentiate between domestic (urban type uses) and agricultural
water sales but do not include a more detailed breakdown of domestic uses
into residential, industrial, commercial and governmental use categories.
As is shown on Table 1, all water sold by the District has been purchased
from the Authority and no local water is produced. Also, while sales o.f
water for agricultural purposes have remained essentially the same over
the past 15 years, domestic water demands have increased at the rate of
approximately 8 percent per year .

E, Current Water Use Within the Costa Real MWD
A total of 12,894.7 acre feet of water was distributed and sold within the
boundaries of the District in Fiscal Year 1983-84 as shown in Table 1. Of
this total, 3,591.9 acre feet was used for agricultural irrigation while
9,302.8 acre feet was used to meet urban water demands. The District had
a total of 11,080 domestic water service connections at the end of Fiscal
Year 1983-84.
Although the urban water use category includes demands for residential,
industrial, commercial and governmental uses, the District does not
maintain records of water use data for these sub-categories •
On the basis of a current Fiscal Year 1983-84 population of approximately
42,000 persons (estimated on a straight line projection of figures in
Appendix "C"), average per capita annual water consumption within the
District is 0.221 acre feet or about 198 gallons of water per person per
day .
F. Projected Water Use Within the Costa Real MWD to the Year 2000
Projected water use within the District to the Year 2000 is graphically
shown on Figure 4. The projection is based on the following assumptions:
*
*
Anticipated population increases within the District as projected by
the San Diego Association of Governments (see Appendix "C") will occur.
The per capita demand of both existing and future population for
domestic (urban) water will remain unchanged at 0.221 acre feet per
year through the Year 2000,
Data used in preparing the estimated water use curve in Figure 4 is
summarized as follows:
Estimated Projected Water Use in Acre Feet
Year Population Domestic Agricultural Total --
1990 59,315 13,100 3,600 16,700
1995 73,788 16,300 3,600 19,900

CHAPTER III
CURRENT WATER CONSERVATION MEASURES
A. Introduction
Costa Real Municipal Water District (District) started a water
conservation program in 1975, prior to the 1976-77 drought emergency.
Early program efforts were oriented toward a long-term public information
program and cooperation with the regional water conservation programs of
the San Diego County Water Authority (Authority). During the drought
emergency period, District programs were expanded and many new programs
were implemented. Since the 1976-77 drought emergency, most of the
original water conservation programs have been continued, but on a public
information level rather than as an emergency situation .
A complete water conservation program should be based on each water supply
agency doing what is most suited to its powers and operations within its
service area. As such, it is most appropriate to have the District pursue
water conservation activities that are more specific and local in nature
while leaving the large-scale and regional water conservation programs to
the appropriate regional water purveying agencies .
The District's entire water conservation program has been established and
developed on the above premise. Its current water conservation programs
and activities are discussed in the following section .
B. Current Water Conservation Measures of the District
1. Measures to Reduce Demands
a. Public Information
Literature-Brochures: The District has distributed brochures and
water conservation material throughout its service area primarily
by means of inserts in water bills prior to the transfer of
billing responsibilities to the City of Carlsbad in 1984. The
District also publishes periodical newsletters emphasizing
conservation. Additional handouts and data are maintained at the
District office and are supplied to the public and service
organizations.

Dis~: The District has constructed and operated water
conservation displays at industrial fairs within its service area,
Speakers Bureau: Public presentations pertaining to all aspects
of water service are available to clubs and organizat~ons
requesting speakers from the District. Directors and staff
alternate, as appropriate, in giving presentations and attending
civic functions .
Tours: Facility and field operation tours are conducted for
various schools, groups and community organizations on an
as-requested basis to promote water awareness and conservation.
b. In-School Education
General: The District has retained a public relations consultant
to develop and implement in-school water awareness activities for
both elementary and junior high grade levels .
Watch Our Water: The District's Watch Our Water (W.O.W.) program
has received much public attention, drawing widespread
participation and support from parents, faculty, and community
leaders. Faculty are in-serviced and provided with instructional
materials to supplement curriculum activities related to water
awareness. An annual awards presentation ceremony spotlights and
officially recognizes students and others who have participated in
W,O,W. program activities and is a high point for all involved in
the program .

c. Mechanical Measures (Device Distribution)
Retrofit Devices: Retrofit water conservation device packages
which included toilet tank water displacement devices and shower
head flow restrictors were distributed to essentially all
households within the City of Carlsbad in 1977 as part of a State
Department of Water Resources (DWR) pilot water conservation
study. Results of the study showed that approximately 20% of all
households reported that the devices were installed.
Currently, a supply of this type of water conservation kits is
maintained at the District office where they are available to the
public free of charge .
d. Promotional Programs
Demonstration Gardens: In 1981 the District installed a low water
using demonstration garden adjacent to its headquarters building
in Carlsbad. Placed in a highly visible location, the garden
contains several drought-tolerant trees and numerous low-water use
plants. Benches and a drinking fountain for those who use the
Park & Ride lot or the bus stop adjacent to the grounds also serve
to attract the public to the garden. Services to construct the
garden were donated by a local landscape firm, with additional
support from volunteer groups and service organizations within the
community. The District currently maintains the garden area.
Technical Assistance: Information and assistance in water-related
matters is provided to organizations and the general public by
District staff on an as-requested basis .

e. Rate Structures, Bills
Uniform Pricing: The District changed from declining block rate
structures to a single uniform rate structure during the drought
emergency in 1976. This change was to insure that all water used
would be purchased at the same rate per unit of water and
eliminated the incentive to use excessive amounts of water to
obtain a lower per-unit water rate .
As a result of the 1984 merging of some of the functions of the
District with those of the City of Carlsbad, the District no
longer bills the individual water service customers. All water is
sold by the District to the City of Carlsbad at a uniform,
non-declining rate, however, and the City's water rate to the
retail water service customers is also a uniform, non-declining
rate.
f. Metering
Existing Services: To insure accurate accountability for all
water delivered, all existing water service connections to
District facilities are metered. All meters are read by City of
Carlsbad personnel on a monthly basis and each water customer
receives a bill which includes a statement of the total amount of
water used during the billing period .
New Services: District and City ordinances require that any new
service connection to District facilities include an appropriate
water meter to accurately account for all water delivered through
the connection .
Metering Maintenance and Replacement Program: By checking and
billing the amount of water delivered through each meter on a
monthly basis, slow reading or stuck meters are quickly spotted by
City of Carlsbad personnel. Improperly operating meters are then
promptly repaired or replaced by the City .

g. Regulations, Ordinances
Wasting Water Ordinance: The District has established its
position, by Ordinance, that no water user shall waste water
supplied through the District's distribution facilities. The
District has also designated procedures to be followed to enforce
its position on eliminating the wasteful use of water should such
enforcement be deemed necessary.
2. Measures to Maximize System Efficiency
a. Water Audits
The District conducts a water audit on an annual basis to compare
total water sales with water acquisitions and purchases. This
comparison identifies the amount of water not directly reflected
as metered water sales and enables the District to review the
need, if any, for implementation of formal water loss reduction
programs .
b. Source Meters
All water sold by the District is purchased from the San Diego
County Water Authority. These purchases are metered and the
District has an accurate record of all water supplied into its
distribution system .
c. Leak Detection
District personnel are instructed to watch for and report
suspected system water leaks. All such reported leaks, as well as
all leaks reported by the general public and by other agencies are
promptly investigated and corrected.
d. System Pressure Controls
The District has installed and maintains various pressure reducing
facilities to insure adequate but not excessive pressures
throughout its water distribution system .

e. Corrosion Control
The District has cooperated with Metropolitan Water District in
programs to ascertain what, if any, chemical changes occur when
water is transported through various types of pipelines. Also, an
anode system of corrosion control has been installed at the San
Marcos Creek Bridge in a test program designed to determine the
best way to reduce pipe damage caused by electrolysis. Extensions
to the program now include other critical areas throughout the
system .
3. Measures to Increase Supply
a. Wastewater Reclamation and Reuse
Although wastewater collection, treatment and disposal or
reclamation services within the District boundaries are performed
by other agencies, the District has, for several years, pursued
studies of water reclamation to help prepare for growing water
demands .
b. Water Exchanges and Transfers
The physical interconnection of the District facilities with those
of adjacent water purveying agencies increases system flexibility
and provides alternate sources of water to District areas during
unanticipated emergencies and short-term planned system shutdowns.
As with most other retail water suppliers in western San Diego
County, however, the District looks to the San Diego County Water
Authority, its water supplier, to act as the lead agency in
insuring adequate long-term supplies of water to meet all demands
within its service area .

C. Regional Water Couservatiou Measures by Other Agencies which~Benefit
:nc uistr1ct Area
No discussiou of water couservation activities and programs within the
District's service area would be complete without inclusion of the
overlapping and regional programs of the two major area wholesale water
purveyors: The San Diego County Water Authority and the Metropolitan
Water District of Southern California. These r~gional activities
supplement and complement the local activities of the District and when
all taken together, form a complete water conservatiou program.
l. Conservation Measures by the San Diego County Water Authority
The following highlights the current regional water conservation
programs which have been implemented by the Authority over the past
ten years to benefit its 24 member agencies, including the District.
More detailed informatiou regarding the regional water conservatiou
activities of the Authority are presented in Appendix •D• .
a. Measures to Reduce 1\emsnds
l) Public Informatiou
Brochures I Handouts & Publicatious: A wide selectiou of
brochures, handouts, and publications prepared by the
Authority and other agencies and institutions (both public and
private) are available free of charge to groups, organizatious
and the general public.
Film Library: The Authority maintains a film library on water
conservation and related subjects for loan to community
organizations and other interested parties.

Display Program: Mobile display units are set up by the
Authority at public institutions, shopping centers, home and
energy shows and other public places. The displays are used
to depict water development in the San Diego County area and
to distribute water awareness and conservation literature.
Reports, Newsletters, etc.: The Authority publishes reports,
newsletters and other material on an as-needed basis
throughout the year .
Radio Talk Shows, Television: Interviews are periodically
arranged for directors and staff personnel of the Authority to
discuss current water issues .
Speakers Bureau: Authority staff are available for
water-related presentations to any interested group or
organization within its service area .
Mass Media Campaign: Water awareness announcements of 10 and
JO-second duration prepared by the Authority are being
broadcast on various television channels in the San Diego
County area on a regular basis throughout the year .
2) In-School Education
Elementary School Programs: The Authority employs two
full-time teachers who each give approximately 4 water
conservation and awareness programs per day to students at the
elementary school level. Approximately one-half of the time
of a newly-hired public relations assistant will also be
devoted to student teaching as the programs are expanded. The
school program directly reaches over 20,000 students per year.

3) Mechanical Measures (Device Distribution)
Retrofit Devices: To date, over 200,000 water conservation
kits have been distributed, primarily by Authority member
agencies and service organizations, to households within the
Authority service area .
Water conservation kits are supplied free of charge to the
public and other agencies upon request. Kits are also
distributed at the annual Del Mar Fair and at other public
functions in conjunction with water awareness programs or
displays.
4) Promotional Programs
Low-Water-Use Demonstration Gardens: The Authority has
constructed a low-water-use demonstration garden at the Del
Mar fairgrounds and exhibits the garden each year during the
fair, The garden is also made available as a setting for
functions and activities of other organizations and groups
throughout the year .
To encourage the construction of more such gardens, the
Authority has formally offered to financially participate in
an amount up to $2,000 in the design cost of any new
low-water-use demonstration garden constructed by its member
agencies .
Water Conservation Awards: Water conservation awards are
presented annually by the Authority at the Del Mar Fair to
both individuals and industry in recognition of their
contribution to water conservation.

Study on Turfgrass Irrigation: The Authority, in conjunction
with other major water purveyors, is co-sponsoring a research
project to produce a broad set of data on turfgrass water
requirements and irrigation methodology which can be used for
development of water saving irrigation practices. Results of
the study conducted at the University of California at Irvine
will be published by the end of 1985 .
5) Metering Programs
Meters: All water delivered by the Authority to its member
agencies is metered .
b. Measures to Maximize System Efficiency
1) Water Audits
System-wide water audits are conducted by the Authority on at
least a monthly basis. Any unexplained water losses are
immediately investigated .
2) Source Meters
All water entering and leaving the Authority pipeline system
is completely metered. Each Authority meter receives a
complete maintenance and calibration check at least every 4
months .
3) Leak Detection
Because of 100% metering, water audits, centralized system
control and visual inspection of all pipelines on a regular
basis, water losses due to pipeline leakage are quickly
noticed and corrected. If undetected leakage is suspected,
field investigations and appropriate mechanical and electronic
leak detection tests are conducted .

3) Leak Detection (cont.)
Leaks are a very rare occurrance, and in most months there is
no water loss. During months when there has been an
unaccounted water loss, the average loss for the month has
been less than 0.6% .
4) Preventative Maintenance
The Authority's current preventative maintenance program
provides the optimum schedule of maintenance for all equipment
requiring periodic maintenance, including valves and meters.
The program is constantly being updated.
5) Valve Exercising
All valves within the Authority water distribution system are
lubricated and exercised at least every 6 months .
c. Measures to Increase Supply
1) Metropolitan Water District of Southern California
The Authority constantly encourages its water supplier, the
Metropolitan Water District of Southern California (MWD) to
increase the total amount of water available to its member
agencies by any means at its disposal.
2) Other Areas or Agencies
The Authority is currently investigating the possibility of
its obtaining water directly from outside the MWD service area
either on a short-term or long-term basis.
3) With its Member Agencies
The Authority encourages local water development projects of
its member agencies and often participates in these projects
and water storage projects.

2. Conservation Measures by the Metropolitan Water District of
Southern California
The following summarizes the current regional water conservation
programs which have been implemented by the Metropolitan Water
District of Southern California (MWD). These activities involve both
public participation programs coordinated with its member agencies and
other organizations and water management programs to contribute to the
efficient use of water by itself and its member agencies. More
detailed information regarding these programs can be found in Appendix
'"E" •
a. Measures to Reduce Demands
1) Public Information
Literature, Brochures: MWD currently distributes
approximately 500,000 pieces of literature annually to its
member agencies, schools, libraries, industries, other
organizations, and individuals.
Publications: One full-color magazine entitled Aqueduct
published quarterly, one newsletter entitled Focus on Water
published up to ten times per year, and one magazine entitled
People, an internal publication, are prepared and distributed
by MWD. Each publication is distributed to over 20,000
readers.
Films: MWD furnishes films promoting water awareness and
conservation to its member agencies, libraries and schools
free of charge. A free lending film library is also
maintained to provide films to any interested organization or
individual .

Exhibits and Related Programs: MWD maintains approximately 70
exhibits which are used to display materials to encourage
water awareness plus water and energy conservation. The
exhibits are placed in high traffic areas such as banks,
shopping malls, fairs, water agency lobbies and other areas
deemed appropriate .
MWD also participates in local fairs including the Del Mar
Fair in San Diego County, usually presenting live programs and
shows .
Speakers Bureau:
by approximately
MWD's speakers bureau is currently staffed
40 formally trained employee volunteers.
Numerous presentations on water conservation and other water
issues are conducted in each member agency area, including the
Authority, each year .
Advertising: Since 1977, MWD's advertising program has been a
major public information campaign emphasizing water
conservation. The campaign includes paid television, radio,
billboard and newspaper advertising, plus public service
announcements, news releases, and other activities designed to
capture public attention .
News Releases: MWD issues many news releases and features
each year to more than 250 major and local newspapers. During
fiscal year 1983-84 more than 200 different news releases were
issued, many of these containing a water conservation message.
~: MWD offers tours of its facilities to interested
groups, organizations, or individuals. Metropolitan's
directors also sponsor one-day and three-day tours of
Metropolitan's Colorado River Aqueduct facilities and the
Department of Water Resources' State Water Project
facilities. All tours include a discussion of water
conservation.

Committees: Several current MWD committees are operating to
encourage water conservation in the various public and private
sectors and to assist the member agencies in water
conservation activities .
2) In-School Education
Elementary School Programs: MWD's comprehensive in-school
education program includes teacher training workshops, a
planned curriculum with educational materials for the teacher
and pupil, and audio-visual aids. Last year's program
included participation of 2700 teachers and 79,000 students.
Numerous other programs and facility tours are also offered to
students and teachers .
High Schools and Colleges: Upon request, MWD, furnishes
speakers to conduct water-related programs, including
conservation programs, for high school and college classes
free of charge .
3) Mechanical Measures (Device Distribution)
Retrofit Devices: MWD has sponsored or participated in
numerous "water conservation kit" distribution programs in its
service area, including the area covered by the Authority.
The "kits" commonly contained toilet tank displacement bags,
shower flow restrictors, and dye tablets to detect leaks
between the toilet tank and bowl .
Other Agencies: MWD continues to coordinate and disseminate
information regarding the programs of other agencies which
directly or indirectly result in water being conserved. These
programs include installation of low-flow shower heads and hot
water pipe insulation and are sponsored by public and private
power utility companies .

4) Promotional Programs
Low-Water Use Landscaping: Since almost one-half of all
residential water used in urban areas is used for landscape
irrigation, MWD actively promotes methods to reduce this water
demand. Efforts include:
* Preparation and distribution of literature and films on
low-water-using landscape.
* Construction of a Demonstration Garden of attractive
low-water-using plants at its Los Angeles Headquarters
Building .
* Working with nurseries to maintain inventories of
low-water-using plants.
* Participation in studies of turfgrass water requirements
and water use in residential landscapes.
Work with Large Water Users: MWD, in conjunction with other
agencies, is working on a program to encourage manufacturers
of water using equipment to consider reduced water use in
future equipment designs .
Work with Other Agencies: MWD actively participates in the
efforts and programs of other agencies (including State and
local agencies) to insure the maximum effectiveness of water
conservation activities and to avoid costly duplications of
effort .
MWD's Water Conservation Coordinator is available to assist
the0 member agencies in developing or expanding their water
conservation activities and to help insure that proposed
programs are implemented by the most appropriate agency.
5) Rate Structures
Uniform Rate: All water delivered by MWD to its member
agencies for municipal and industrial (urban) uses carries a
single uniform rate .

6) Metering Programs
Meters_: All water delivered by MWD to its member agencies is
metered .
b. Measures to Maximize System Efficiency
1) Water Audits
MWD performs water audits of its system and facilities on a
weekly and monthly basis. These audits include an accounting
for sales, evaporation losses, seepage, local uses,
construction uses, Metropolitan's uses, gains from rainfall
and infiltration, changes in groundwater storage, and gains
and losses in reservoir storage. Unidentified losses range
from one to three percent, and any unexplained losses are
immediately investigated .
2) Source Meters
All water entering the MWD distribution system is metered, and
all deliveries to member agencies are also metered .
Each MWD meter receives a complete maintenance and calibration
once every 12 months .
3) Leak Detection
Since annual unidentified water losses usually range from only
one to three percent, MWD does not maintain formal leak
detection equipment or crews. If undetected leakage is
suspected, staff is assigned or consultants are hired to
determine leak locations, if any, and the leaks are repaired.

4) Preventative Maintenance
MWD's current preventative maintenance program implemented in
1975, provides the optimum schedule of maintenance for all
equipment requiring periodic maintenance, including valves and
meters. The program is constantly being updated .
5) Corrosion Control
An extensive corrosion control program including cathodic
protection where necessary, is conducted to reduce corrosion
damage to facilities .
6) Valve Exercising
All valves within the MWD water distribution system are
lubricated and exercised at least every 12 months .
c. Measures to Increase Supply
1) Local Projects
MWD assists in financing local water development projects of
member agencies (primarily wastewater reclamation projects)
which will result in more overall water being available within
the MWD service area. This allows potable water that would
have been used in the local project area to be released for
use in other parts of the MWD area.
2) Replenishment Programs
Member agencies not requiring MWD water for immediate use are
encouraged, by means of an interruptible water rate somewhat
less than the urban water rate, to purchase and store water in
underground groundwater basins and surface reservoirs for use
during water shortage periods .
III-17
.. ... .. ... .. ... .. ... .. ... .. ...

Special short-term reduced rate programs to encourage water
"stockpiling" against future shortages are occasionally
implemented when imported water supplies are especially
plentiful .
3) Increases in Imported Water Supplies
MWD is actively encouraging the completion of the State Water
Project as well as negotiating with other agencies to obtain
additional supplies of water from the Colorado River, all with
the goal of increasing the total amount of water available for
distribution to its member agencies .

CHAPTER IV
ALTERNATE CONSERVATION MEASURES AND IMPLEMENTATION SCHEDULE
A. Introduction
The purpose of this chapter is to summarize current water conservation
measures of the Costa Real Municipal Water District (District) detailed in
Chapter III that will be continued or expanded, to describe and evaluate
alternate conservation measures that could be implemented by the District
to improve the efficiency of water use, and to set forth a schedule of
implementation for selected alternate conservation measures.
As stated in Chapter III, the District's current water conservation
programs are intended to be specific and local in their application and
complement and enhance the regional water management programs of the San
Diego County Water Authority (Authority) and the Metropolitan Water
District of Southern California (MWD). The alternate water conservation
measures and the continuation or expansion of current programs discussed
hereinbelow are also local and specific in nature and are programs that
are suited for District implementation. Alternate conservation measures
of a more regional nature will be implemented by the Authority and MWD as
discussed in Appendices "D" and "E" respectively.
B. Ex_E!nded and Alternate Conservation Measures of the District
Unless otherwise specifically noted below, all water conservation measures
currently implemented and being practiced by the District, as set forth in
Section B of Chapter III, will be continued at or above their current
level of effort .

1. Measures to Reduce Demands
a. Public Information
Literature-Brochures: The District may increase its distribution
of water conservation data and brochures provided by the Authority
and MWD through direct mailing to its customers. Consideration
will also be given to preparing a local water conservation
brochure specifically aimed at the water users within the
District's service area.
b. In-School Education
The District will designate a staff representative to attend
school presentations conducted by Authority teachers within
District boundaries. The District's representative will provide
valuable assistance in answering questions on local matters and
will emphasize the importance of the program to the District.
c. Device Distribution
Retrofit Devices: Although retrofit water conservation kite which
included toilet tank water displacement devices and showerhead
flow restrictors were widely distributed several years ago, the
District will notify all its urban water users that such kits are
still available free of charge.
Faucet Aerator Information Program: The District will consider
establishing a public information program recommending the
installation of aerators on faucets. Such devices are easily
installed, are cost efficient, and have anti-splash benefits that
make them highly acceptable .

d. Promotional Programs
Moisture Sensors Information Program: The District will obtain or
develop information on the advantages and availability of
hand-held moisture sensors and make such information available to
the general public. By indicating the moisture content in soils,
these devices assist in reducing over-watering thereby promoting
conservation .
Water Conservation Coordinator: A Water Conservation Coordinator
will be designated from District staff to provide information on
all types of water conservation programs and answer questions from
the general public. The Coordinator would also work closely with
the Authority to assist in implementing regional conservation
programs with local benefit.
e. Rate Structures -Bills
Previous Year's Use on Bills: The District will work with the
City of Carlsbad to determine the feasibility of modifying the
City's water billing procedure to one that will show the previous
year's water use for the same billing period. This additional
information will increase the customer's awareness of water use
patterns and will help to prevent gradual increases in water use.
f. Regulations, Ordinances
Special Regulations During Emergencies:
with the City of Carlsbad, will develop
The District, working
and adopt special
regulations to be implemented during periods where total regional
water demands cannot be met due to drought or other condition.
Restricted uses may include the hosing down of driveways and other
paved surfaces, the washing of automobiles and the irrigation of
lawns and other landscaping during daylight hours .

D. Implementation of Expanded or Alternate Conservation Measures
Table 2 contains the implementation schedule for the expanded or alternate
conservation measures discussed in the preceding Sections Band C. The
implementation dates shown in the Table are target dates and may be
influenced by several factors including:
* The need for detailed and possibly time consuming studies to determine
the feasibility and cost effectiveness of several of the measures .
* The need for approval of the District's Board of Directors of some, if
not all, of the measures prior to their implementation .
* The need to coordinate many programs, especially those directly
dealing with the retail water user, with the City of Carlsbad .
* The need to formally coordinate new water conservation programs with
the Authority and MWD to avoid unnecessary and potentially costly
duplications of effort .

CHAPTER V
SUPPLY DEFICIENCY ANALYSIS
As shown on Table 1 and discussed in detail in Chapter II, all water delivered
by the Costa Real Municipal Water District (District) is filtered imported
water purchased from the San Diego County Water Authority (Authority). The
Authority, in turn, purchases its entire water supply from the Metropolitan
Water District of Southern California (MWD). Use of local waters within the
District boundaries to supplement the imported water supplies was terminated
in the 1950's because the rapidly increasing mineral content of local water
made it unusable for municipal purposes .
Since any water supply interruption to the District facilities would only
occur as a result of a supply deficiency to either the Authority or MWD, the
reader is referred to the Urban Water Management Plans of these two water
wholesaling agencies (see Appendices "'D"' and ""E"') for a complete evaluation of
the regional water supply situation .
A. Supply Deficiencies that Occur on a Regular Basis
The District has experienced no regular or frequent water supply
deficiencies during the period of record from Fiscal Year 1969-1970 shown
on Table 1 .
B. Supply Deficiencies that Occur Only During Periods of Drought
The only reduction of water supply to the District because of drought was
a coordinated voluntary reduction in supplies from the Authority of
approximately 10% during the 1976-77 drought period. This cutback
occurred not because of inadequate supplies, but as an effort to help
mitigate the severe effects of the drought in other areas of the State.

CHAPTER VI
FUTURE WATER MANAGEMENT PRACTICES WHICH COULD
SUPPLY ADDITIONAL WATER OR REDUCE WATER DEMANDS
As shown in Section II-F, an increasing domestic water demand is projected for
the area served by the Costa Real Municipal Water District (District). To
meet this increasing demand, additional volumes of imported water must be
purchased by the District from its water supplier, the San Diego County Water
Authority (Authority) .
Section 10632 of the Act requires that any Urban Water Management Plan that
projects a future water use indicating the need for expanded or additional
water supplies must include an evaluation of the following:
* Waste water reclamation
* Exchanges or transfer of water on a short-term or long-term basis
*
*
*
Management of water system pressures and peak demands
Incentives to alter water use practices, including fixture and
appliance retrofit programs
Public information and educational programs to promote wise use and
eliminate waste
* Changes in pricing, rate structures and regulations
The evaluations that follow deal with the above categories that are specific
and local in nature and can be planned and implemented by the District.
Categories that involve or require a more regional approach receive detailed
evaluations in the Urban Water Management Plans of the Authority and the
Metropolitan Water District of Southern California (MWD) and the reader is
referred to those Plans (see Appendices "D" and "E"),

A, Waste Water Reclamation
1. Regional Studies
An Area-Wide Water Quality Management Plan (208 Plan) was adopted for
the San Diego County area by the Comprehensive Planning Organization
(CPO) on June 19, 1978. The 208 Plan recommended the implementation
of 20 separate water reclamation projects in the San Diego region. In
response to those recommendations, the San Diego City/County Water
Reuse Study was formed and funded under Section 201 of the Federal
Water Pollution Control Act to investigate the feasibility of
developing cost effective water reclamation projects in the San Diego
region,
As the region's wholesale water supplier and distributor, the
Authority was requested to investigate and prepare the feasibility
reports for the majority of the proposed projects under the 201
Study. At the direction of the County, work has been temporarily
suspended, but it is anticipated that work will soon resume and the
studies will be completed .
The reader is referred to the appropriate sections of the Urban Water
Management Plans of the Authority and MWD (see Appendices "D" and "E")
for the complete evaluation of waste water reclamation as it can be
applied towards increasing the total amount of water available for use
within the region .
2. Local Situation
As stated in Section III, B, 3., waste water collection, treatment and
disposal or reclamation services within the District's boundaries are
performed by completely separate and unrelated agencies. The City of
Carlsbad provides the majority of the waste water services within the
District •

3. Evaluation
Although the District actively participates in area waste water
reclamation studies and efforts, it is not the lead agency in such
endeavors. The District looks to the Authority and to the local
sewering agencies to take the lead in developing and implementing
waste water reclamation programs to make more water available to the
entire region.
Exchanges or Transfers~ of Water on a Short-Term or Long-Tepn Basis
1. Discussion
The District currently has water system interties with four of its
neighboring water retailing agencies: The Olivenhain Municipal Water
District, the San Dieguito Water District, the San Marcos County Water
District and the City of Oceanside, These interties are for the
purpose of transferring limited amounts of water between agencies
during emergencies and short-term planned or unanticipated water
system outages.
2. Evaluation
No water agency adjacent to the District has local water supplies that
can satisfy more than a fraction of each agency's current demand, much
less provide a short or long-term additional supply to the District.
This category, therefore, is not a viable water supply option.

C. Management of Water System Pressures and Peak Demands
1. Water System Pressures
As previously discussed, all water supplied by the District is
purchased from the Authority. Water is delivered into the District's
distribution system from Authority aqueducts located east of and at an
elevation generally higher than the District service area. This
elevational difference coupled with the existing pressure in the
Aqueduct system results in high to extremely high pressures in the
water entering the District system .
Since the District provides service downhill from its supply
connections to the Authority aqueducts, water pressures throughout the
District facilities increase even more. To insure adequate but not
excessive water pressure to its consumers within its hilly service
area, the District has currently established about 20 mechanically
regulated water service pressure zones. Each zone is established to
provide an average water service pressure of approximately 60 pounds
per square inch (psi). Pressures naturally vary in any pressure zone,
however, with the water consumers living on the hillsides receiving
somewhat lower pressure water than those living downhill in the
valleys. Should excessively high pressures occur at the lower
elevation limits of pressure zones, separate small pressure regulators
are installed at each service connection to reduce water pressure to an
appropriate level. The District is also planning to install a 40 kW
hydroelectric generator at a pipeline pressure reducing point.
The District has carefully designed and installed its water
distribution system to take full advantage of existing water pressures
and elevational changes. This farsighted approach is in itself called
conservative since it conserves energy by eliminating the need to pump
water anywhere within its service area .

2. Peak Demands
Water demands by individual customers on the District's water
distribution system are subject to wide fluctuations from day to day
and throughout the year. These fluctuations in demand are a common
and expected occurrence in any water distribution system and are
influenced or prompted by such factors as customer habits or routines,
time of day, day of week and climatic condition. Actual water system
peak demands on District facilities fall well within the limits
commonly experienced by retail urban water purveyors .
The District has constructed several water reservoirs including the
600 acre foot Squires Reservoir to provide emergency storage and
supplemental supply to buffer system peaks. Additional reservoirs are
currently under construction or in. the planning stages to meet
increasing peak demands for water occasioned by area growth .
3. Evaluation
The low pressure limits in the District's water service pressure zones
are established as the minimum pressure that will still allow the
acceptable operation of water using appliances, fixtures and
irrigation devices. Any reduction in pressure would adversely affect
the proper operation of existing fixtures and would create significant
public objection. Other than the occasional provision of individual
pressure regulators for higher pressures services, no significant
pressure reduction program appears viable .
D. Incentives to Alter Water Use Practices, Including Fixture and Appliance
Retrofit Pro~ram
1. Existing and Future Programs
As discussed in detail in Chapters III and IV, the primary District
programs currently implemented or proposed relating to incentives and
encouragements to alter water use practices focus on the following
categories:

* Distribution of information and retrofit devices that can be installed
in existing plumbing fixtures to reduce water usage .
* Establishment and maintenance of a low-water-using demonstration
garden to show the attractiveness of low-water-use landscaping .
2. Evaluation
All commonly accepted programs and practices that can be applied
through a "local" effort by the District were identified and discussed
in Chapters III and IV. All of these programs have either been
implemented or are proposed for implementation .
E. Public Information and Educational Pro~rams
A wide range of public information and education programs have either been
developed or are proposed for development by the District, as discussed in
detail in Chapters III and IV, and are summarized below. In addition to
the below-listed programs, the District also supports the regional
programs of the Authority and MWD .
1. Public Information Program
The District's public information program includes the distribution of
brochures and water conservation material; the operation of water
conservation displays; maintenance of a speakers bureau; and the
provision of tours of District facilities .
2. Educational Programs
In addition to the District's "Watch Our Water" program aimed at
students at the elementary school level, the District also supports
the teaching programs of the Authority .

3. Evaluation
It was recommended in Chapter IV that the District consider an
expansion of its public information program, primarily through an
increase in its dissemination of literature, brochures and data, and
to designate a staff representative to directly participate in
educational programs with the Authority.
F. Changes in Pricing, Rate Structures and Regulations
1. Changes in Pricing and Rate Structures
All urban water conveyed by the District is sold at a uniform,
non-declining rate to the City of Carlsbad as discussed in Chapters II
and III .
2. Changes in Regulations
Existing and proposed regulations of the District were discussed in
Chapters III and IV .
3. Evaluation
Since the above water conservation programs are in place, no further
evaluation is included .

An ac~ to 11dcl and repeal Part 2.6 (commencing with Section
10610) to Divisic,n 6 of the Water Code, relating to water conserva-
tion. •
(Approved by Governor Sept~mber 21, 1983. Filed with
Secretary of State September 22, 1983.l
LEGISLATIVE COUNSEL'S DIGEST
AB 797, Klehs. Water: management planning.
(l) Under existing law, local water suppliers may, but are not
required to, adopt and enforce water conservation plans.
This bill would require every urban water supplier providing
w2.ler for municipal purposes to more than 3,000 customers or
supplying more than 3,000 acre-feet of water annually to prepare and
adopt, in accordance with prescribed requirements, an urban water
management plan containing prescribed elements. The bill would
require the plan to be filed with the Department of Water Resources,
and would require the department to annually prepare and submit
to the Legislature a report summarizing the status of the plans. The
bill would require each supplier to periodically review its plan in
accordance with prescribed requirements, would specify
requirements for actions or proceedings arising under the bill, and
would specify related matters.
The bill would make legislative findings and declarations in this
~-onnection.
The provisions of the bill would remain in effect only until January
l, 1991.
(2) Article XIII B of the Californi11 Constitution and Sections 2231
and 2234 of the Revenue and Taxation Code require the state to
reimburse local agencies and school districts for certain costs
mandated by the state. Other provisions require the Department of
Finance to review statutes disclaiming these costs and provide, in
certain cases, for making claims to the State Board of Control for
reimbursement.
This bill would impose a state-mandated local program as its
requirements would be applicable to local public agencies.
However, the bill would provide that no appropriation is made and
no reimburscmeut is required by this act for a specified reason.
The people of the Stute of OJifornia do enact as follows:
SECTION l. Part 2.6 (commencing with Section 10610) is added

COSTA REAL MUNICIPAL WATER DISTRICT
The Costa Real MWD was formed in 1954, pursuant to the California Water Code
Section 71000. The district joined the SDCWA the same year with the purpose of
acquiring rights to imported water for the City of Carlsbad and the adjoining
areas .
The Costa Real MWD is governed by a five-member board. The district serves an
area of 31.8 square miles, about 86 percent of which currently has water service.
Although Costa Real MWD is a rapidly urbanizing district, due to the rapid growth
of Carlsbad, much rural area remains. Agricultural water use accounts for about
one-third of water production.
The population of Costa Real MWD was 30,2.00 in 1980. It is forecasted to in-
crease rapidly to 59,300 by 1990 and to 86,800 by 2.000.

SUMMARY
SAN DIEGO COUNTY WATER AUTHORITY
URBAN WATER MANAGEMENT PLAN
This Summary presents the major components of the Urban Water Management Plan
for the regional area served by the San Diego County Water Authority
(Authority). The Plan consists of six chapters and appendices which describe
the efforts of the Authority and its member agencies to promote efficient
water use. Each of these is briefly described in this Summary .
CHAPTER I: INTRODUCTION
.-Chapter I explains the purpose, preparation, and adoption of the Authority's
.,. Urban Water Management Plan and provides a format for the remaining chapters .
...
., The Plan has been prepared responsive to the Urban Water Management Act (Act),
"" ... .. ...
... ...
"" ... .. ... .. ... .. ... ..
loo ..
Ill
"" ..
Water Code Sections 10610 through 10656 which were added by Statutes 1983,
Chapter 1009, and became effective on January l, 1984 .
Although the Authority is not legally required under the Act to prepare a
regional urban water management plan, it has prepared this Plan to supplement
the plans of its member agencies and to present a summary of the current and
future water management activities within its service area. The Plan includes
a description of those water conservation and water management activities that
the Authority currently conducts or may conduct within the next five years on
a regional basis in cooperation with its member agencies. It also includes a
summarized discussion of the activities being conducted by its member
agencies. Detailed activities of the member agencies will be included in the
plans prepared by those agencies .
A Public Hearing, conducted by the San Diego County Water Authority, was held
on December 6, 1985 at the Authority headquarters for the purpose of obtaining
public comment and input on the draft Plan. The final Plan was adopted by the
Board of Directors of the Authority on December 12, 1985 by Resolution No.
85-44.

CHAPTER II: GENERAL INFORMATION AND PAST, CURRENT, AND PROJECTED WATER USE
The Authority was organized on June 9, 1944, under the County Water Authority
Act of 1943, for the primary purpose of importing Colorado River water to San
Diego County in order to supplement the local water supplies which were
rapidly becoming inadequate .
Currently, the Authority supplies water to its 24 member agencies shown on
Figure 1 and listed below:
Cities: Del Mar, Escondido, National City,
Oceanside, Poway, and San Diego
Water Districts: Helix, Otay, and San Dieguito
Irrigation Districts: South Bay and Santa Fe
Municipal Water Districts: Bueno Colorado, Costa Real, De Luz Heights,
Olivenhain, Padre Dam, Rainbow, Ramona,
Rincon del Diablo, Valley Center, and Yuima
Public Utility District: Fallbrook
Federal Agency: Pendleton Military Reservation
Count_y: Water District: San Marcos
The Authority is responsible for delivering imported wster wholesale to its
member agencies which, in turn, either directly or indirectly supply over 95
percent of the population of San Diego County.
Many of the Authority's member agencies have some local sources of water.
Still, local supplies can meet only a portion of the area's needs. For the
remainder, the member agencies look to the Authority to supply their needs for
additional wster .
All water imported to the Authority facilities comes through the vast delivery
systems of the State Water Project and the Colorado River Aqueduct via The
Metropolitan Water District of Southern California .

To assure a continuing water supply for the region, the Authority annexed to
The Metropolitan Water District of Southern California (MWD) in 1946. Today,
the Authority is one of 27 member agencies of MWD. Member agency status
entitles the Authority to directly purchase water for its needs from MWD on a
wholesale basis. Since MWD is its sole source of imported water, the
Authority looks to MWD to insure, to the best of its ability, that adequate
amounts of water will be available to satisfy future demand. This water is
used by the Authority to satisfy up to 96 percent of the water demand within
its service area .
Local production of surface water and ground water sources within the
Authority service area varies from 4 to about 32 percent of the total annual
water supply of the Authority's member agencies. Twelve of the 24 member
agencies are essentially dependent upon imported water supplied by the
Authority. The 12 remaining agencies have local supplies which satisfy
varying portions of their water needs .
Currently, MWD has five pipelines providing both treated and untreated water
to the Authority. These pipelines, forming the two San Diego Aqueducts,
extend south from MWD's Lake Skinner to a point approximately six miles south
of the Riverside-San Diego County line where they join the Authority
facilities.
Within San Diego County, the Authority operates and maintains 221 miles of
large diameter pipeline, 105 miles of access roads, 75 service connections to
its member agencies, 2 hydroelectric power generating stations, and numerous
vent structures and flow regulation devices.
The design capacities of the Authority pipelines at the point of delivery from
MWD are:

In 1970, the Authority service area covered 753,000 acres and a population of
1.26 million. Annual water use amounted to 323,000 acre feet of which
agricultural irrigation accounted for 83,000 acre feet, the remainder
supplying residential, industrial, commercial, and governmental demands.
Local production accounted for 24 percent of the total water used within the
area .
1975
The Authority service area had increased moderately by 1975 to include 762,000
acres supporting a population of 1.56 million. Annual area water use was
384,500 acre feet, 96 percent of which was supplied by the Authority.
Agricultural uses accounted for 94,000 acre feet of the total supply.
1980
The Authority service area had grown to 899,000 acres in 1980 with a
residential population of 1.8 million. Annual water use amounted to 462,000
acre feet, 30 percent of which came from local sources. Agricultural demand
accounted for 102,000 acre feet of the total supply.

Current Water Use
A total of 540,262 acre-feet of water was distributed and sold within the
boundaries of the Authority in Fiscal Year 1983-84. Of this total, 123,867
acre feet were used for agricultural irrigation while 416,394 acre feet were
used to meet urban water demands. The Authority gross service area at the end
of Fiscal Year 1983-84 was 902,224 acres of which 424,930 acres, or 47
percent, were served water .
On the basis of a Fiscal Year 1983-84 population of approximately 2,006,000
persons, average per capita annual water consumption within the Authority is
0.21 acre feet or about 188 gallons of water per person per day.
Projected Water Use
.._ The population within the Authority service area is projected to grow to
"" ...
"" ...

... ...
approximately 2.6 million by the year 2000. With the water conservation
programs of the local and regional water purveying agencies included in this
Plan, total water use in 2000 is projected to average approximately 695,000
acre feet per year. The projection of total water demand and use within the
Authority service area to the year 2000 presented in Table 1 was developed by
summarizing the projected demands of each of the Authority's 24 member
agencies. This information in shown graphically on Figure 2.
CHAPTER III: CURRENT CONSERVATION MEASURES
A complete water conservation and management program is based on each water
supply agency pursuing those activities which are most suited to its powers
and operations within its service area. As such, the water conservation and
management programs and activities taking place throughout the service area of
the Authority are being undertaken by the various area water agencies in the
following manner:

Activities of the Authority Member Agencies/Retail Water Purveyors are
local and specific in nature. Efforts are directed towards selected
groups of individuals and certain types of water use. Programs involve
a direct one-on-one contact with the retail water user .
Activities of the Authority deal with educational and promotional
programs and contact with the general public on a service-area-wide
basis. Direct support of the activities of the Authority member
agencies is a major program element, Very little direct contact with
the retail water user is attempted or possible .
Activities of the Metropolitan Water District (MWD) center on large
scale, regional education, public information, and promotional measures
and issues. The programs involve some general public participation and
are coordinated with MWD's member agencies and other organizations,
Extensive communication and coordination between the local and regional water
agencies is maintained to maximize effort and effectiveness while minimizing
program duplication. The regional programs supplement and complement local
activities and, together, form a complete water conservation program .
Current Water Conservation Measures of the Authority Member Agencies/Retail
Water Purvezors
Most water conservation programs of the Authority member agencies/retail water
purveyors (hereinafter Local Agencies) were started either before or during
the 1976-77 drought emergency. Since the 1976-77 drought emergency, most of
the Local Agencies' original water conservation have been continued on a
public information level,
Public Information Programs: Essentially all the Local Agencies
distribute information to the public on water conservation through a
variety of programs including brochures, advertising, bill inserts,
exhibits, facility tours, speaker bureau, films, and a staff
conservation coordinator.

Previous Year's Use on Water Bills: Approximately one-half of the
Local Agencies have modified their water billing procedures to show the
previous year's water use for the same billing period. The remaining
Local Agencies have limitations on existing computer billing programs
which presently prevent including such information •
In-School Education: Many Local Agencies have designated staff
representatives to attend the area school programs conducted by
Authority teachers to add support and to answer questions pertaining to
the local water systems.
Retrofit Devices: Retrofit water conservation device packages, which
included toilet tank water displacement devices and showerhead flow
restrictors, were distributed to households within their service areas
by most Local Agencies in 1977 •
Supplies of this type of water conservation kit are currently
maintained at most Local Agency offices where they are available to the
public free of charge.
Demonstration Gardens: Several Local Agencies have constructed, or are
in the process of constructing, low-water-use landscaping demonstration
gardens. These gardens are situated in areas that allow easy public
access and are designed to show the attractiveness and ease of
maintenance of low-water-use plants and shrubbery •
Low-Water-Use Planting Lists: Several Local Agencies, either in
conjunction with their low-water-use demonstration gardens or as a
separate effort, make low-water-use planting lists available to the
public .
Staff Water Conservation Coordinator: Several Local Agencies have
designated a member of their staff to act as the coordinator of water
conservation activities .

Technical Assistance: Essentially all Local Agencies provide
information and assistance in water-related matters to organizations
and the general public .
Uniform Pricina: Most Local Agencies have changed from declining block
water rate structures to a single uniform rate structure •
Metering Services: To insure accurate accountability for all water
delivered, all existing water service connections in all Local Agencies
are metered .
Wasting Water Ordinance: Almost all Local Agencies have established
their positions, by ordinance, that no water user shall waste water
supplied through their distribution facilities .
Waste Water Reclamation: Of the Local Agencies who do have waste water
collection, treatment, disposal, and reclamation responsibilities,
seven actively participate in reclamation programs and activities, and
the balance cooperate with others .
Water Exchanges and Transfers: Presently, the Local Agencies have
better than 100 interconnections throughout the Authority' service area
to increase their system flexibility and provide alternate sources of
water during unanticipated emergencies and short-term, planned system
shutdowns .
System Efficiency Maximization: To varying degrees, the Local Agencies
conduct water audits, leak detection programs, and corrosion control
programs; have expanded water use records; and utilize source meters
and system pressure controls .
Water Conservation Measures of the San Diego County Water Authority

Public Information Program: The Authority distributes information to
the public on water conservation through a variety of programs
including brochures, publications, films, displays, reports,
newsletters, mass media advertising, transit advertising, and a public
speakers bureau .
School Education Programs: The Authority has developed a comprehensive
school education program to promote water awareness and conservation.
Authority staff teachers make presentations to over 20,000 students per
year .
Low-Water-Use Demonstration Gardens: The Authority has constructed a
low-water-use demonstration garden at the Del Mar Fairgrounds and
exhibits the garden each year during the Fair and other activities
throughout the year .
To encourage the construction of more such gardens, the Authority
financially participates in an amount up to $2,000 in the design cost
of any new low-water-use demonstration garden constructed by its member
agencies. The Authority's goal is the development of 40 demonstration
gardens throughout the region at libraries, fire stations, and other
areas where public viewing is convenient.
Water Conservation Awards: The Authority's Water Conservation Awards
are presented annually to individuals and industry in recognition of
contributions to water conservation .
Studies: The Authority is co-sponsoring a research project on
turfgrass water requirements and irrigation methodology for development
of water-saving irrigation practices,
Water Audits: System-wide water audits on the aqueduct system are
conducted by the Authority on at least a monthly basis. Any
unexplained water losses are immediately investigated.

Source Meters: All water entering and leaving the Authority pipeline
aystem is completely metered. Each Authority meter receives a complete
maintenance and calibration check at least every four months •
Leak Detection: Becsuse of 100 percent metering, water audits,
centralized system control, and visual inspection of all pipelines and
easements on a regularly-scheduled basis, water losses due to pipeline
leakage are quickly noticed and corrected. Leaks are a very rare
occurrence. When there has been an unaccounted water loss, the average
loss has been less than 0.6 percent .
Measures to Increase Supply: The Authority is represented on the Board
of Directors of the Metropolitan Water District (MWD) by six
directors. These Authority representatives and0 Authority staff working
with MWD staff all strive to improve the quantity and enhance the
reliability of urban Southern California's water supplies .
The Authority has investigated the possibility of its directly
obtaining water from outside the MWD service area either on a
short-term or long-term basis. Actual implementation of such
approaches has been deferred to MWD since the benefits of an additional
water source would be to the whole MWD service area •
The Authority encourages local water development and water storage
projects of the Local Agencies and often participates in these projects.
CHAPTER IV: ALTERNATE CONSERVATION MEASURES AND IMPLEMENTATION SCHEDULE
The purpose of this chapter is to summarize current water conservation
measures of the San Diego County Water Authority (Authority) detailed in
Chapter III that will be continued or expanded; to describe and evaluate
alternate (new) conservation measures that could be implemented by the
Authority to improve the efficiency of water use; and to set forth a schedule
of implementation for selected alternate conservation measures.

level may occur responsive to adverse changes in the area water supply
picture or the implementation of new public information or water
conservation programa .
Committees: The Authority will consider forming a Water Conservation
Advisory Committee, composed of staff and representatives from member
agencies, interested organizations and individuals, to offer advice and
suggestions on developing and implementing future water conservation
programs,
Display• Program: This activity will be expanded to include special use
of displays for new programs .
Radio Talk Shows, Television: This activity will be increased to
provide additional information and publicity regarding special
promotional programa .
Speakers Bureau: This activity will be expanded to encourage more
participation from member agencies. The Authority will prepare
"speaker kits" containing text, slides, and other aids to assist member
agency speakers .
Mass Media Campaign: The focus of television commercials and transit
advertising will be redirected from intermittent, general water
awareness messages to specific promotional programs presently being
developed .
Elementary School Programs: This activity will continue at essentially
the same level,
Secondary School Programs: The existing Authority program for junior
high and high schools will be updated and expanded,
Retrofit Devices: The Authority will continue to make water
conservation kits available to its member agencies, organizations, and
the general public upon request free of charge.

Faucet Aerator Information Program: The Authority will conaider
establishing a public information program recommending the installation
of aerators on faucets.
Moisture Sensor Information Program: Tue Authority will develop
information on the advantages and availability of hand-held moisture
sensors and make such information available to the general public.
Low-Water-Use Demonstration Gardens: A new focused theme program
emphasizing low-water-use landscaping for residential applications will
be developed .
Implementation of Expanded or Alternate Conservation Measures
Implementation of the expanded or alternate conservation measures may be
influenced by several factors including:
* The need for detailed and, possibly, time-consuming studies to
determine the feasibility and cost effectiveness of several of the
measures .
* The need for approval of the Authority's Board of Directors of some of
the measures prior to their implementation •
* The need to coordinate many programs with the Authority's member
agencies and obtain their participation and support.
* The need to formally coordinate certain new water conservation programs
with The Metropolitan Water District of Southern California to avoid
unnecessary and potentially costly duplications of effort.
A summary of the current, expanded, and alternate (new) programs and
activities of the Authority and its member agencies is included in Table 2.
The implementation schedule for expanded and alternate conservation measures
is shown on Table 3.

CHAPTER V: SUPPLY DEFICIENCY ANALYSIS
All water delivered by the Authority is imported Northern California and
Colorado River water purchased from The Metropolitan Water District of
Southern California (MWD). Use of local water, developed and distributed by
Authority member agencies, to supplement the Authority's imported water
supplies varies from year to year depending primarily on rainfall conditions.
The Authority has no local water sources of its own and looks to MWD to supply
and satisfy its total water needs.
Supply Deficiencies that Occur on a Regular Basis
The Authority has experienced no regular or frequent water supply deficiencies.
Supply Deficiencies that Occur Only During Periods of Drought
The only reduction of water supply to the Authority because of drought was a
coordinated, voluntary reduction in supplies from MWD of a proposed 10 percent
during the 1976-77 drought period. The actual water use reduction achieved by
the Authority was about 16 percent.
AbilitI to Meet Short-Term Deficiencies
During periods of short-term water supply deficiencies, water shortages must
be offset through local water supplies and water in storage. The following
summarizes these short-term supplies.
Local Water Supplies: Local and imported water is stored by the_member
agencies in anticipation of future short-term water shortages. The
amount stored for such emergencies is about 200,000 acre feet.
Authority Supplies: All water delivered by the Authority is purchased
from MWD, and with the exception of storage contracts with the City of
San Diego, the Authority currently does not have the ability to store
any water. To rectify this sitatuion, the Authority is currently in

the design and approval stage of its first water storage project: Pamo
Dam and Reservoir .
CHAPTER VI: FUTURE WATER MANAGEMENT PRACTICES WHICH WOULD SUPPLY ADDITIONAL
WATER OR REDUCE WATER DEMANDS
An increasing domestic water demand is projected for the area served by the
Authority. To meet this increasing demand, additional volumes of imported
water must be purchased by the Authority from its water supplier, The
Metropolitan Water District of Southem California (MWD).
Section 10632 of the Act requires that any Urban Water Management Plan that
projects a future water use indicating the need for expanded or additional
water supplies must include an evaluation of the following:
*Wastewater reclamation
* Exchanges or transfer of water on a short-term or long-term basis
* Management of water system pressures and peak demands
* Incentives to alter water use practices including fixture and appliance
retrofit programs
* Public information and educational programs to promote wise use and
eliminate waste
* Change in pricing, rate structures, and regulations
The information that follows pertains to the above categories that are
semi-regional in nature and can be planned and implemented by the Authority
for its service area.
Waste Water Reclamation
Implementation of cost-effective water reclamation projects in the San Diego
region could initially produce 50,000 acre-feet of water or about 10 percent
of the needs of the region.

The Authority is working on the San Pasqual Valley Water Reclamation Project
as an additional water source and mitigation for some of the impacts caused by
the construction of Pamo Dam and Reservoir. The Project will reclaim ll,000
acre-feet of treated waste water per year for irrigation and ground water
recharge .
There are numerous local agencies within the service area of the Authority
with responsibility for waste water collection, treatment, disposal, and,
where required or feasible, reclamation. Although most treated waste water in
the region is still being disposed of via ocean outfalls, interest in waste
water reclamation is rapidly increasing, and reclamation projects, where cost
effective, are being developed and implemented.
Exchanges or Transfers of Water on a Short-Term or Long-Term Basis
To reduce the impact of water supply interruption within the Authority service
area, most member agencies have water system interties with their neighboring
water supply agencies. However, this is not a viable water supply option for
any appreciable amounts of water except for local emergencies.
Management of Water System Pressure and Peak Demands
Water s1stem Pressures
The Authority has carefully designed and installed its major aqueduct
water supply system to take full advantage of existing water pressures
and elevational changes thereby eliminating the need to pump
significant amounts of water anywhere within its service area.
The Authority member agencies have installed and operate their water
distribution systems to insure adequate, but not excessive, pressures
to their customers. Since the Authority has no control or influence
over the pressures utilized in its member agencies' distribution
systems, management of water system pressures must be reserved for the
member agencies supplying water to the retail water consumers .

Peak Demands
Member agencies look to the Authority to supply their peak week water
needs. Demands above these peaks are buffered somewhat by member
agency water storage and local supply facilities .
Water demands by individual customers on the member agencies' water
distribution systems are subject to wide fluctuations from day to day
and throughout the year. System storage is used to offset peak flow
requirements .
Public Information and Educational Pro~rams
The Authority's Public Information Program includes brochure, report, and
publication distribution; speakers bureau; drought-tolerant garden program;
mass media and transit advertising; and display programs •
The Authority currently conducts a major school program for fourth and sixth
grade students and for junior high and high school students on a somewhat
lesser scale. The potential for expanding the secondary level school program
is currently being studied .
Changes in Pricing
The Authority charges uniform rates for the water it supplies to its member
agencies on a wholesale basis .
