2. BOARD OF DIRECTORS OF THE CARLSBAD MUNICIPAL WATER DISTRICT: Adopt , approving adoption of the Memorandum of Understanding Resolution No. 1260 regarding Urban Water Conservation Best Management Practices in California.
ITEM EXPLANATION:
Urban Water Management Plan - 2005 Update
The California Water Code requires all urban water suppliers within the state to prepare urban water
management plans and update them every five years. These plans satisfy the requirements of the
Urban Water Management Planning Act of 1983 including amendments that have been made to the
Act. The attached plan constitutes the 2005 update for the Carlsbad Municipal Water District.
The Urban Water Management Plan (UWMP) looks at historic and current water demands for the
CMWD service area, compares water supplies with demands through 2020 and examines potential
new supplies to meet those demands. Annual water demand within the service area is expected to
grow from about 22,200 acre feet currently to almost 29,000 acre feet by 2020. The Urban Water
Management Plan identifies imported and local water supplies expected to meet these future water
demands, thereby ensuring a reliable water supply for Carlsbad. Local water supplies discussed in
the plan includes development in groundwater recovery efforts, recycling projects, water
conservation measures, and seawater desalination.
This 2005 UWMP update addresses the recent water supply issues concerning both potable and
recycled water. The update discusses seawater desalination as a potential for additional water
supplies, for both CMWD and the region. This UWMP update reviews the recent Water Purchase
Agreement between CMWD and Poseidon Resources. This agreement allows CMWD to purchase
100 percent of its potable water supply from Poseidon Resources. This supply would be desalinated
seawater from a facility constructed in Carlsbad. This UWMP update also includes discussion of the
MOU between CMWD and the San Diego County Water Authority (SDCWA). That MOU allows
CMWD to purchase up to 5,000 acre-feet of desalinated seawater as its local supply from the
SDCWA.
The UWMP update also reviews the potential for water transfers and the status of Phase II of the
CMWD Recycled Water Program. Discussion of the Recycled Water Program includes identifying
the recent extentention of additional recycled water distribution pipelines; pump stations and the
completion of a 4.0 mgd Recycled Water Treatment Facility.

Sinnatory Membership to the MOU of the California Urban Water Conservation Council
In 1991, the California Urban Water Conservation Council (CUWCC) was formed through a
Memorandum of Understanding (MOU) by its participating agencies and to address urban water
conservation efforts. Signatories to the MOU agree to implement a set of fourteen cost-effective
Best Management Practices (BMPs). These BMPs are recognized worldwide as a framework for
advancing the efficient use of valuable water resources and include the following:
BMP #01 - Residential Surveys
BMP #02 - Residential Plumbing Retrofit
BMP #03 - System Water Audits, Leak Detection And Repair
BMP #04 - Metering with Commodity Rates
BMP #05 - Large Landscape Programs And Incentives
BMP #06 - High-Efficiency Clothes Washer Rebates
BMP #07 - Public Information Programs
BMP #08 - School Education Programs
BMP #09 - Commercial, Institutional And Industrial Programs
BMP #I 0 - Wholesale Agency Assistance Programs
BMP #I 1 - Conservation Pricing
BMP #I2 - Conservation Coordinator
BMP #I 3 - Water Waste Prohibition
BMP #I4 - Residential Ultra Low Flow Toilet (ULFT) Replacement Programs
Each BMP has a set of specific requirements for documentation and implementation. A water
agency can exempt itself from implementing a BMP if it can show that the practice is not cost-
effective, if adequate funds are not available, or if the agency does not have the legal authority to
implement the practice. Staff has reviewed the BMPs with water conservation staff at the San Diego
County Water Authority (SDCWA).
Thirteen of the 14 BMP’s apply to Carlsbad. (BMP#10 applies only to wholesale agencies and
CMWD is a retail agency) Those thirteen BMP’s are already in place, some by virtue of programs
sponsored by the SDCWA. These are described below.
BMP #01 - Residential Surveys The CMWD has offered water audits to all residential customers since
1991. These audits are free of charge and funded entirely by the District. Audit components include: reviewing water usage history with the customer; checking for leaks inside and outside; checking for low
water use plumbing devices; inspecting irrigation systems; recommending improvements; and providing
conservation literature.
BMP #02 - Residential Plumbins Retrofit A City ordinance was adopted in August, 1991 which
requires Ultra Low Flow Toilets (ULFTs) in new construction and retrofits. State legislation effective
January 1, 1992 requires the installation of efficient plumbing in new construction (1.6 gpf toilets; 2.5
gpm showerheads; I .O gpf urinals; and 2.2 gpm kitchen/bathroom faucets). State legislation
effective January 1, 1994 requires that only ULFTs be sold in California. CMWD offers free faucet
aerators, water-saving showerheads and toilet tank devices to all customers.
BMP #03 - System Water Audits, Leak Detection And Repair CMWD reviews monthly water
production records and compares the amount of water produced against the monthly-billed
consumption records to determine the amount of unaccounted for water. District employees
routinely drive water transmission line routes to visually look for water leaks. In addition, CMWD has
an aggressive meter exchange program where older, less accurate water meters are exchanged for
new, accurate ones. As a result, CMWD’s annual water loss percentage has averaged about five
percent for the past five years.
Page 3
BMP #04 - Meterinq with Commoditv Rates Metering of all water use and billing by volume has long
been the standard practice of the CMWD.
BMP #05 - Larqe Landscape Programs And Incentives CMWD’s Water Conservation Specialist has
been trained to conduct landscape water audits with in-house equipment and software and has
been doing so since 1991. In addition, since 1990, the District has participated in SDCWA’s
contractor-operated large landscape program for landscapes greater than I acre. This program
provides a thorough survey of the irrigation system, soils and plant materials, and calculates an
irrigation schedule based upon technology developed by Cal Poly San Luis Obispo.
BMP #06 - High-Efficiencv Clothes Washer Rebates CMWD began participating in SDCWA’s HEW
rebate (now voucher) program in 1998. This program offers a financial incentive to customers who
replace their conventional clothes washing machine with a water and energy efficient washing
machine.
BMP #07 - Public Information Proqrams CMWD’s public information program includes a quarterly
newsletter mailed to all customers, a web site at www.ci.carlsbad.ca.us/water/index.html, computerized
landscape advice, water awareness calendars, bill inserts, information on the water bill regarding
previous usage, an annual promotional event at the local mall, various promotional campaigns, and
membership in North County Water Agencies, a consortium of 11 water agencies.
BMP #08 - School Education Proqrams CMWD has education programs available for all elementary
grade levels, such as: Water Wabbit (K-1 St); annual poster contest (4‘h); watershed awareness
program (2nd & 5‘h); water quality education (grade and high school); Admiral Splash (4‘h); and
California Smith, W.I. (6th).
BMP #09 - Commercial, Institutional And Industrial Proarams CMWD participates in SDCWA-
operated CII program, which provides point-of-purchase vouchers to CII customers for ultra-low-
flush toilets, low-flow and waterless urinals, high efficiency, coin-operated clothes washers and
cooling tower conductivity controllers. Point-of-purchase vouchers encourage implementation of
water saving devices as the voucher reduces the up-front cost to businesses as well as reducing
water, sewer and energy costs for ten or more years. Reduced utility costs help to create a
business-friendly environment and a strong economy.
BMP #I 0 - Wholesale Aqencv Assistance Proqrams - Not Applicable to CMWD.
BMP #I1 - Conservation Pricinq CMWD currently has a conservation rate of $1.44 per unit
available to all customer classifications based on their monthly usage relative to meter size.
BMP #I2 - Conservation Coordinator One Water Conservation Specialist and one Management
Assistant assigned to the City’s Environmental Programs Division of the Public Works Department
devote 80% and 50% of their time respectively to coordination of conservation programs and
activities.
BMP #I3 - Water Waste Prohibition In 1991, CMWD adopted the ‘Carlsbad Water Ethic’ which
specifies responsible water use and is designed to promote the most reasonable, wise and efficient
use of water Carlsbad. Practices include:
New landscaping shall incorporate drought-tolerant plant materials and drip irrigation
systems, wherever possible.
Water can never leave the user’s property due to over-irrigation of landscape.
Watering must be done during the early morning or evening hours to minimize
. . .
BMP #I4 - Residential Ultra Low Flow Toilet (ULFT) ReDlacement Prosrams CMWD began offering
rebates worth up to $75 for the replacement of older toilets with ultra-low flush toilets in 1990. Since
1991, CMWD has been participating in SDCWA’s rebate and voucher programs.

There are a number of benefits to the CMWD becoming a signatory to the MOU and formally
adopting the BMPs:
Credibility for water conservation programs based on an MOU developed with the support of
environmental groups.
Access to Technical Advisors, as well as CUWCC Council publications, studies, and library
materials.
On-line database with password protected data on agency’s water conservation activities
through the BMP Reporting Process.
Training for utility staff in Conservation, Water Audit, Lead Detection and BMP Reporting.
Access to loans and grants offered through the California Department of Water Resources.
Previous conservation efforts have been associated with periods of drought and were therefore
reactive. Adoption of the BMPs illustrates a proactive approach to responsibly and effectively
managing the CMW D’s water resources.
CUWCC membership signatories are divided into three categories:
Group 1 - Consists of water suppliers. A “water supplier” is defined as any entity, including a city,
which delivers or supplies water for urban use at the wholesale or retail level.
Group 2 - Consists of public advocacy organizations. A public advocacy organization is defined as
a nonprofit organization whose primary mission is protection of the environment, or who has a clear
interest in advancing the BMP’s, and whose primary function is not the representation of trade,
industrial or utility entities.
Group 3 - Consists of other organizations with an interest in the purposes of the CUWCC which are
not included in Group 1 or Group 2.
Based on the benefits above, staff recommends that the CMWD become a Group 1 signatory to the
memorandum of understanding. Becoming a signatory simply requires the CMWD Board
President‘s signature on the signature sheet of the most recent (March IO, 2004) MOU. The
signature sheet is then forwarded to the CUWCC where they vote, as a formality, to accept the
CMWD as a member.
ENVIRONMENTAL REVIEW:
The Urban Water Management Plan is exempt from CEQA in accordance with Section 10652 of the Urban Water Management Planning Act.
FISCAL IMPACT:
This Urban Water Management Plan has no financial impact. However, the projects and policies that may evolve from its findings could have a financial impact. These impacts would be handled as
the projects or policies are implemented.
Page 5
CUWCC membership dues have a fixed component of $1,000 for less than 3,000 connections or $2,000 for more, and a variable component of 2.4 cents a connection and 3 cents an acre foot delivered per year. For the CMWD, this calculates to $3,230 per year. The Water Authority and
Metropolitan Water District pay the annual dues (50% each) for all member agencies. Staff expects
that this practice will continue.

Introduction
CALIFORNIA URBAN WATER MANAGEMENT PLANNING ACT
The California Water Code requires all urban water suppliers within the state to prepare
urban water management plans and update them every five years. These plans satisfy the
requirements of the Urban Water Management Planning Act of 1983 including amendments that
have been made to the Act. Sections 1061 0 through 10656 of the Water Code detail the
information that must be included in these plans, as well as who must file them. Appendix E
contains the text of the Act. This report constitutes the 2005 update to the District‘s 2000 Urban
Water Management Plan.
Major amendments made to the Act since the Water Authority’s 2000 Plan was prepared
include:
Description of specific water supply projects and implementation schedules to meet
projected demands over the planning horizon;
Description of the opportunities for the development of desalinated water;
Additional information on groundwater, where groundwater is identified as an existing or
planned water source;
Description of water quality over the planning horizon; and
Description of water management tools that maximize local resources and minimize
imported water supplies.

In addition, the California Department of Water Resources (DWR) will consider whether
the urban water supplier has submitted an updated plan when determining eligibility for funds
made available pursuant to any program administered by the department.
statewide concern; however, the planning for that use and the implementation of those plans
can best be accomplished at the local level.” The Act requires that each urban water supplier,
providing water for municipal purposes either directly or indirectly to more than 3,000 customers
or supplying more than 3,000 acre-feet of water annually, shall prepare, update and adopt its
urban water management plan at least once every five years or before December 31, in years
ending in five and zero. In accordance with the Act, the Carlsbad Municipal Water District is
required to update and adopt its plan for submittal to the California Department of Water
Resources (DWR) by December 31,2005.
According to the Act, “The conservation and efficient use of urban water supplies are of

DWR has prepared a checklist that lists items to be addressed in each agency’s plan,
based on the Act. The checklist allows agencies to identify where in their plan they have
addressed each item. The District has completed this checklist, cross-referencing the Act‘s
sections and this report’s page numbers. The completed checklist is included in Appendix D.
SENATE BILLS 610 AND 221
Water Code Sections 10910 through 10914 and Government Code Sections 65867.5,
66455.3, and 66473.7 (commonly referred to as SB 610 and SB 221) amended state law to
improve the link between information on water supply availability and certain land use decisions
made by cities and counties. SB 61 0 requires that the water purveyor of the public water system
prepare a water supply assessment to be included in the environmental documentation of
certain large proposed projects. SB 221 requires affirmative written verification from the water
purveyor of the public water system that sufficient water supplies are available for certain large
residential subdivisions of property prior to approval of a tentative map.
Chapter 4 of the CMWD 2005 Plan contains documentation on the existing and planned
water supplies being developed by the San Diego County Water Authority and the City of
Carlsbad.

While preparing the 2005 Plan, the District coordinated its efforts with a number of
agencies to ensure that data and issues are presented accurately. The District attended
workshops conducted by DWR to discuss the requirements of the Act and ensure coordination
with other agencies, including the San Diego County Water Authority (SDCWA) and its member
agencies and the Metropolitan Water District (MWD), on regional elements of the Plan. In
addition, SDCWA submitted information for and reviewed elements of the District's Plan. The
District also worked closely with the City of Carlsbad in the preparation and review of Plan
elements.
In addition, in preparing the recycled water elements of this plan, the District consulted
with the agencies responsible for the existing and potential sources of recycled water, including
the Vallecitos Water District, the Leucadia Wastewater District, and the Encina Wastewater

1063 1. A plan shall be adopted in accordance with this chapter and shall do all
of the following:

projected population, climate, and other demographic factors affecting the
supplier's water management planning. The projected population estimates shall

projections within the service area of the urban water supplier and shall be in
five-year increments to 20 years or as far as data is available. .
Climate
Carlsbad's climate is characteristically Mediterranean with mild temperatures year round.
This mild climate is derived equally from the warm ocean water being pulled north from Mexico
and from its subtropical, semi-desert locale. The result is temperatures averaging 58 degrees in
January and 73 degrees in July, with an average annual rainfall of about 10 inches.
Other Demographic Factors
boundary is the Pacific Ocean. Contiguous cities include Oceanside to the north, Encinitas to the
south, and San Marcos and Vista to the east. The Carlsbad Municipal Water District's service
area is entirely within the City of Carlsbad's boundaries and covers approximately 32 square
miles (85 percent of the city). A map of the District's boundaries is located on page 10.
Carlsbad is located in the north coastal region of San Diego County. Its western
The median age of Carlsbad residents is 39 years. The average household is 2.46
persons per dwelling unit. The median family income is estimated at $77,151 per year. More
than 50% of Carlsbad residents are employed in professional, managerial, and administrative
occupations. Over 90% of residents have completed high school and 45% are college
graduates.
In 2004, employment in service industries in Carlsbad ranked as the highest employment
sector, followed closely by manufacturing and retail trade.
Carlsbad's Water Supply History
provided by the privately held Carlsbad Mutual Water Company through the utilization of local
The City of Carlsbad was incorporated in 1952. Water demands for the area were initially
6
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
supplies. Subsequently purchased by the City, the Mutual Water Company constructed a series
of wells, pumping stations and transmission facilities to quench the thirst of residential,
commercial and agricultural users.
The Mutual Water Company obtained rights to 2,382 acre feet of water from the “Mission
Basin” of the San Luis Rey River Valley in western Oceanside, and held a license by the State
Division of Water Rights for another 1,000 acre feet annually. Additionally, water rights for 150
acre-feet annually were held from Calavera Creek and a lesser amount from Agua Hedionda
Creek. The original license was for irrigation purposes and was later changed to recreational
and fire protection purposes.
As demands for water increased, another problem was being realized with the existing
water system. In times of high demand, seawater intrusion occurred when water levels within the
San Luis Rey River basin dropped. The gradual degradation of water quality prompted the
Mutual Water Company to abandon all attempts to utilize this water. This created the need for
imported sources.
CMWD was formed as a vehicle to bring imported water to the unincorporated areas of
Carlsbad and to wholesale water to the newly formed City of Carlsbad. Its first meeting was held
on March 22, 1954. CMWD became a member of the San Diego County Water Authority that
same year.
In January 1990, CMWD became a subsidiary district of the City of Carlsbad. The
Carlsbad City Council acting as the Water District Board of Directors governs the District.

Past Drought, Water Demand, and Conservation Information
Water use in Carlsbad is closely linked to the local economy, population and weather.
Over the last half century, a prosperous local economy has stimulated population growth, which
in turn produced a relatively steady increase in water demand. However, fluctuating economic
and weather conditions in the 1990s and lingering effects from the 1987-1 992 drought resulted

Demand (AF)
% Change
in deviations from historic demand patterns. By 1999, a new combination of natural population
increases and job creation surfaced as the primary drivers of water consumption increases.
Historically, the District’s peak year water demand occurred in 1989, when a record
amount of nearly 18,000 acre-feet was purchased serving a population of 52,133 and 22,726
residential dwelling units. In calendar year 1999, demands exceeded the 1989 historical peak
and reached a total water demand of over 19,000 acre-feet. In 2005 the projected water demand
is estimated at 22,000 acre-feet. Following the 1987-1 992 drought, the CMWD service area
experienced significant reductions in water use. This reduction in potable water use was
attributable to several factors, including the economic recession, water conservation measures
taken by the District as a result of the drought, the introduction of recycled water, and relatively
plentiful rainfall.
The years following the drought showed a steady growth in population, and water
demand grew to match this population growth. In 1997 water demand jumped almost 14 percent
over 1996 demands, evidence of the great economic growth and construction boom in Carlsbad.
Water demand peaked again in 1999, as Carlsbad’s population continued to grow. Carlsbad’s
population continues to grow and the resultant water demand for fiscal year 2004-2005 was
20,904 acre-feet. Table 2-2 shows the historic water demand each year within the CMWD
service area.

TABLE 2-2
Historic Water Use in the CMWD Service Area (1995-2004)
As stated earlier, historic water demand peaked in 1989 with nearly 18,000 acre feet
purchased. Since then, water conservation practices and higher water rates have resulted in a
reduction in the demand for water. Increases in water usage beginning in 1992 reflect the
growing use of recycled water for irrigation.
The necessity for reduced water consumption by CMWD customers was the result of a
reduction in the available imported water supply from the drought. Although water was not
rationed, the Metropolitan Water District of Southern California placed financial penalties on its
member agencies if they exceeded their water demand of FY 1988-89. MWD enacted this
penalty to discourage any increases in the imported water demand.
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
To avoid paying the financial penalty, CMWD adopted an increasing block rate structure
to discourage high water use. In 1993, this structure was changed to a flat rate. In addition,
water conservation programs were expanded to discourage the use of excessive amounts of
water for irrigation purposes during the drought. CMWD continues to encourage water
conservation for irrigation, particularly the use of recycled water when available.

Chapter 3 - Water Supply Sources
Law
1063 1. A plan shall be adopted in accordance with this chapter and shall do all
of the following:
10631 (b) Identify and quantify, to the extent practicable, the existing and
planned sources of water available to the supplier over the same five-year
increments [to 20 years or as far as data is available.]
Water Supply Sources
Carlsbad is located in a semi-arid coastal desert environment averaging less than 10
inches of rain annually. Prolonged rainstorms are rare. The Carlsbad Municipal Water District
has been 100% reliant on imported water purchased from the San Diego County Water
Authority.
Until 1960, the District's historical water supply included groundwater, surface water and
imported water. Groundwater was obtained from wells in the San Luis Rey River Basin, located
in Oceanside, and wells located along Agua Hedionda Creek in Carlsbad. Surface water was
obtained from Calavera Lake, an earthen dam reservoir designed to capture and treat surface
runoff flowing into Calavera Lake.
Calavera Lake included a water treatment plant and stored groundwater pumped from
wells in the San Luis Rey River basin during the winter months. This groundwater was used later
during peak water demand periods. The Metropolitan Water District conveyed imported water
through aqueducts from the Colorado River. At that time, imported water was not processed
through a water treatment plant, but rather screened and chlorinated prior to use.
Local groundwater and surface water supplies were abandoned in the 1960s due to poor
water quality and the ability to directly supply lower-cost imported water to customers. Overall,
groundwater quality degraded to the point where the levels of total dissolved solids (TDS) in the
wells exceeded 1500 mg/L. The water treatment plant that existed at Calavera Lake was
subsequently abandoned and dismantled. In addition, in 2005, the groundwater wells in the San
Luis Rey well field, a total of 8 wells were removed and abandoned in accordance with California
State Department of Health Services standards.
CMWD began receiving imported water deliveries in 1955 through existing aqueduct
connections located in the City of Escondido. A pipeline was constructed in 1956 by CMWD to
convey imported water directly to Carlsbad and unincorporated areas. From 1962 to 1992,
11
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
CMWD’s water demand was met exclusively by imported water sources.
In 1991 , CMWD began delivering recycled water to supplement its imported water
supply. Through agreements with two other agencies, CMWD obtained 2.0 mgd of recycled
water from the Meadowlark Water Reclamation Facility, and 0.75 mgd from the Gafner Water
Reclamation Plant. These plants are owned and operated by the Vallecitos Water District and
the Leucadia Wastewater District, respectively. Since 1992, recycled water demand has
increased due to new land development projects. These projects connect into a recycled water
system consisting of distribution pipelines, a 2 mgd pump station and two reservoirs with a
combined storage capacity of 2.5 million gallons. Carlsbad began expanding its recycled water
system in 2000. Carlsbad has now completed its own 4.0 mgd Recycled Water Treatment
Facility as part of its Phase 2 program. This is further detailed later in this chapter under
Recycled Water.

imported water sources. However, the District realized early on that not only were they reaching
the limit of local resources in terms of quantity, but also the water quality (high in TDS) was
becoming detrimental to agriculture, which represented a significant portion of the delivered
water supply. So, in 1951, CMWD applied to join the San Diego County Water Authority.
SDCWA had previously joined the Metropolitan Water District of Southern California (MWD) in
order to obtain supplemental water from the Colorado River.
As with many communities in southern California, CMWD has relied on both local and
Currently, CMWD relies on imported water exclusively to meet potable water demands
for residential, commercial, and industrial uses. The water is imported from MWD and treated at
MWD’s Skinner Filtration Plant in Riverside County. The treated water is conveyed to CMWD
through SDCWA aqueducts. Table 3-1 shows current and projected imported water purchases
through 2020.

GROUNDWATER
Until the 1950s, local groundwater was the only source of water for the City of Carlsbad.
The major sources were wells drawing from the Mission Basin of the San Luis Rey River. Wells
were initially developed in 1913. CMWD has rights to 5 cubic feet per second (cfs) of pre-1914
appropriative rights and an additional 750 acre feet per year, up to 5 cfs, that was permitted in
1938. Over the years, the total dissolved solids (TDS) content of the groundwater in the Mission
Basin increased to the point where the use was discontinued. The condition of the wells and
piping system were beyond repair and were subsequently removed in 2005.
CMWD also owns wells originally developed by the Terramar Water Company in the
early 1950s. These wells, referred to as the Cannon Well Field, were purchased from Terramar
in 1958 and used from 1958 to 1962. The largest extraction was only 238 AFY. These wells are
located in the Agua Hedionda Creek near Rancho Carlsbad Golf Course. The golf course
irrigation water is obtained from these wells today.
Other potential groundwater basins include Buena Vista Creek Basin, Encinas Creek
Basin, and the Batiquitos Hydrologic Subarea. These resources have low potential yields, poor
quality, or no available data to substantiate their use in the public water supply. Generally
speaking, these basins do not have geological characteristics or size comparable to Mission
Basin. Collectively, none of these groundwater alternatives would supply even 3 percent of
CMWD’s ultimate need of 28,907 acre-feet per year.
Of the groundwater basins available to CMWD, only the Mission Basin of the San Luis
Rey River has the potential for a viable water resource. This basin has a large drainage area of
565 square miles and consists of alluvium and river channel deposits averaging 150 feet in
depth. The quality is mildly brackish with TDS concentrations ranging from 1,000 to 1,500
milligrams per liter (mg/L). For Carlsbad’s use, the water would need to be treated by a low
pressure membrane, reverse osmosis process to achieve treated water quality in the range of
500 mg/L. The City of Oceanside is currently doing this at their Mission Basin Desalting Facility.
In 2005 Carlsbad completed a study on the cost effectiveness of utilizing the
groundwater from the Mission Basin. This study showed that while the treatment and delivery of
groundwater is feasible, it showed that it is not cost effective. As a result, the CMWD Board
approved staffs recommendation to abandon the well sites and discontinue efforts to utilize this
groundwater source as an alternate local supply at this time.
There were 9 wells total in the Mission Basin. In 2004, two wells were destroyed on the
District’s “Foussat Property” south of Mission Avenue. Seven wells were located north of Mission
Avenue. Six of the remaining 7 wells were located. These 6 wells had all of the equipment
removed, and were inspected and were subsequently removed in 2005. The last well was not

located because it was buried as a result of the Army Core Of Engineers improvements to San
Luis Rey River.
Seawater Desa I ina t ion
In 1999, Poseidon Resources Corporation approached the Carlsbad Municipal Water District
with a proposal to perform a feasibility study on seawater desalination in Carlsbad. In March
2000, the District's Board of Directors instructed staff to prepare a report on this proposal,
including the benefits and impediments to such a project. In short, numerous beneficial aspects
to developing seawater desalination project were identified, but the report also identified many
serious and critical issues that must be addressed and resolved before Carlsbad could obtain a
cost effective, reliable, drought- proof water supply from this source.
The purpose of the staff report was not to attempt to answer the many questions
presented or solve any of the issues presented. The purpose was to identify most of the issues
known at the time in order to put the potential for seawater desalination into perspective.
Poseidon Resources completed their feasibility study in July of 2001. This study showed
that construction of a 50 MGD Seawater Desalination Facility was feasible and recommended
construction of this facility on the Encina Power Plant site (owned by Cabrillo Power). This site
offers advantages of an existing seawater intake, a method of brine discharge and an existing
Regional Board discharge permit.
ENCINA POWER PLANT - SITE OF PROPOSED SEAWATER DESALINATION FACILITY
14 20
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
As a result of their feasibility study, Poseidon offered a proposal to construct a 50 MGD
Seawater Desalination Facility and to sell, to Carlsbad, 10 MGD (or more) of desalinated
seawater. The proposal stated that Poseidon would be responsible for marketing any of the
water not purchased by Carlsbad. Poseidon offered to sell the remaining water to the Vallecitos
Water District, the Vista Irrigation District, the City of Oceanside, the San Dieguito Water District
and the Olivenhain Municipal Water District. They also offered to sell the remaining water to the
San Diego County Water Authority (SDCWA).
The Carlsbad Municipal Water District (CMWD) Board recognized early on that there
were two paths that could lead to the development of a desalination plant in Carlsbad. One
would be a public project owned and operated by San Diego County Water Authority (SDCWA),
developed through the normal public works process of design, bidding, government oversight,
distribution, and pricing. The other would be a private project developed by Poseidon, using
private procurement methods and operating practices, and selling water to public agencies
through both public and private water lines at prices negotiated as part of a water purchase
agreement.
Since June 2000, Carlsbad staff has worked with both SDCWA and Poseidon to develop
agreements that would define how these two possible futures could become one reality. And,
although negotiations with SDCWA were on hold between January and August 2004, staff
continued working with Poseidon Resources on the development of a Water Purchase
Agreement (WPA).
The WPA provides Carlsbad the right to purchase up to 25 Million Gallons Per Day
(MGD) of water from the desalination plant. This water will meet the District‘s water quality
standards, and be provided to the CMWD at specified delivery points. With regard to Reliability,
the agreement provides that if the plant delivers less than a specified amount of water each
year, CMWD will receive a payment of liquidated damages from Poseidon. In addition, the
agreement is conditioned on CMWD receiving a backup supply of water from SDCWA to assure
that local residents water needs are covered at all times.
The guiding principal in negotiating this agreement has been CMWD’s direction that
Carlsbad residents should pay no more for desalinated water than they would otherwise pay for
water delivered from SDCWA. The pricing plan that is currently reflected in the draft WPA
achieves CMWD’s goals with regard to the cost of water.
Since the WPA is based on a Take-If-Delivered concept where CMWD only pays for
water that is actually delivered by Poseidon, there are no payments to Poseidon that are not
directly tied to the delivery of water.
15
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
The WPA includes a number of conditions that must be satisfied prior to CMWD having an
obligation to purchase water from the project. These include the following:

CEQA
a. CWMD cannot commit to purchase any water until all California Environmental
Quality Act (CEQA) processes are complete
b. If the CEQA process has not been completed within 24 months of the date of the
WPA, either party may terminate the agreement.
Water Rates - If Poseidon has determined that the water rates set by the pricing section
of the agreement are insufficient to implement the project; Poseidon may terminate the
agreement.
Applicable Laws and Permits - The agreement requires that Poseidon or its
subcontractors must have complied with all applicable laws, and received all necessary
approvals and permits.
Sale of Remaining Output - If Poseidon has not entered into agreements to sell the
remaining output of the project within 24 months; either party may terminate the
agreement.
Delivery Points - If the parties have not agreed on delivery points within 24 months of the
WPA date either party may terminate the agreement.
Delivery Regime - If the parties have not determined an acceptable delivery regime within
24 months of the WPA date, either party may terminate the agreement.
Delivery Charge - The parties must agree on a mutually acceptable delivery charge.
Monitoring and Testing - The parties must develop a mutually acceptable system testing
and monitoring protocol.
Subsidy - If CMWD has not received the $250 per acre-foot MWD subsidy (or an
equivalent subsidy, from other sources) the agreement may be terminated.
IO. Development Agreement - The agreement is conditioned on the parties entering into a
Development Agreement.
11. Backup Water Supply - The agreement is conditioned on Carlsbad receiving an
acknowledgement from SDCWA that CMWD is eligible to receive backup water when
needed.
12. Cabri//o Consent - Within 24 months, Cabrillo Power must have provided the necessary
consent allowing the CMWD to exercise its rights under this agreement.
The long-term fiscal impact of this agreement is difficult to project. If the project is
successful, CMWD will be purchasing high-quality water from the desalination plant at a price
that is competitive with present SDCWA supplies.
16
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
Extensive testing protocols have been designed into the WPA to identify any potential
problems before water reaches CMWD’s system, and to assure that adjustments are made to
the water quality to eliminate any potential for system damage.
It is unlikely that CMWD will reduce its capital improvement program or other water
system investments due to this agreement. The need to rely on SDCWA for backup water, and
the relative uncertainty that still surrounds this project requires that CMWD continue to develop
its ability to receive traditional water supplies as well as desalinated water.
There is currently no plan to invest CMWD money in the development of this project. The
WPA anticipates a totally private project constructed using private financing. If grant funds
become available to fund portions of the, project, CMWD may reconsider this position.
CMWD may elect to construct and own certain portions of the water distribution system.
Any decision to change the water system Capital improvement Program will be based on a
future analysis of the effect of desalinated water deliveries on existing system design, and will be
subject to Board approval.
Table 3-1.
The potential for desalinated seawater use in the CMWD service area is shown in
Again, the CMWD Board also recognized on that there could be a public project owned
and operated by the SDCWA, developed through the normal public works process of design,
bidding, government oversight, distribution, and pricing.
As a result, the SDCWA and CMWD also reached an inter-agency agreement called an
‘Agreement Memorializing Certain Understandings And Establishing A Framework For
Cooperation’. This agreement commits the parties: the San Diego County Water Authority, the
City of Carlsbad, the Carlsbad Housing and Redevelopment Commission and the Carlsbad
Municipal Water District, to certain intergovernmental, financial and other matters relating to the
Regional Desalination Project, if the SDCWA determines to proceed with the project.
As part of this Agreement, the SDCWA agrees to sell the CMWD up to 5,000 acre-feet of
desalinated seawater annually. This water purchased by the CMWD will be deemed and
designated as the “District‘s Local Water” and will be additional to any water the CMWD may
receive as a member agency of the SDCWA.
In either case described above, the CMWD will increase its water supply reliability
substantially with the implementation of a seawater desalination project in the City of Carlsbad.
Recycled Water
The Carlsbad Municipal Water District began serving recycled water in 1993. The
Meadowlark Water Reclamation Facility (owned and operated by the Vallecitos Water District)
and the Gafner Wastewater Treatment Plant (owned and operated by the Leucadia County
17
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
Water District) currently provide recycled water at a rate of 2.0 million gallons per day (mgd) and
1 .OO mgd, respectively. In 2005, CMWD’s existing recycled water distribution system provided
approximately 2,000 acre-feet per year of irrigation water to 206 meter accounts. Major users
include the Aviara Development and Golf Course, the La Costa Resort and Golf Course, and
CalTrans. Recycled water demands currently exceed available supply.
The District’s 1997 Reclaimed Water Master Plan Update identified a recommended
expansion of the recycled water system that will increase peak supply from 2.75 mgd to 8.0 mgd.
This expansion is referred to as Phase I1 and, as described in the plan update, includes:
constructing a new 4 mgd water recycling facility near the existing Encina Water Pollution
Control Facility and expanding the Meadowlark facility by 1 mgd; constructing 24 miles of 12 to
24-inch distribution and transmission pipelines; and constructing new recycled water pumping
stations. Improvements to an existing earthen dam storage reservoir, referred to as the Mahr
Reservoir, for recycled water storage were also recommended.
Since 1993, the CMWD has been constructing pipelines and requiring developers to
install recycled water facilities in anticipation of the Phase II program. Thus, many existing
potable water irrigation systems are accepting recycled water with little or no modification. Many
of the Phase I1 users are located adjacent to existing recycled water pipelines.
In order to fully implement Phase I1 expansion, CMWD has:
0 Completed all applicable regulatory requirements that affect recycled water
production, storage, distribution and end use.
Addressed all institutional requirements that could have constrained the phased
expansion of the system.
Completed all internal requirements imposed by the expansion, including
adequate staffing for design and construction review and coordination, customer
connection and coordination, and regulatory/institutional coordination; and
adequate system monitoring to ensure ongoing refinement of preliminary design
assumptions.
Completed construction for most critical and/or longest-lead facilities such as the
4.0 mgd Carlsbad Water Recycling Facility in compliance with Bureau of

There are two aspects of water supply reliability to be considered. The first relates to
immediate service needs and is primarily a function of the availability and adequacy of facilities.
This aspect can be classified as emergency reliability. The second aspect is driven by the
availability of water, which is climate-driven and can be classified as resource or supply
reliability. Both SDCWA and MWD are in the process of implementing facilities to enhance
emergency reliability. In addition, certain institutional programs are either being developed or are
being implemented which will address resource reliability in both the near-term (present to 201 0)

Cost of service: SDCWA believes that there must be a nexus between benefits and
burdens at Metropolitan and that SDCWA and all of Metropolitan’s member agencies
should get what they pay for and pay for what they get. SDCWA believes that
Metropolitan must levy a charge for unused capacity and water held ready to serve
member agencies on a standby basis; currently, Metropolitan shifts those costs to the
member agencies who are buying water.
Future investments: SDCWA has proposed that Metropolitan should only make
investments that its member agencies are willing to pay for; SDCWA believes that
Metropolitan must change its current rate structure, which allows member agencies to
“roll off its system, thus shifting the burdens of its investments to those who remain.
Establishment of rights and liabilities: SDCWA believes that Metropolitan’s member
agencies must, by contract or otherwise, be able to ascertain and fix their rights and
liabilities in the Metropolitan system.
Governance and vofinq: The current voting structure at Metropolitan, like the preferential
rights formula, is based on assessed valuation. While the system may have made sense
when Metropolitan revenues were collected from taxes, it no longer makes sense when
the majority of revenues are collected from water rates. SDCWA believes that
Metropolitan’s governance and voting structure should be changed to reflect the interests
of those member agencies who are paying the bills.
Water uualitv: SDCWA pays for but is not served water from the State Water Project that
could bring its water quality up to the standards required by Section 136 of the
Metropolitan Act. It is unfair for SDCWA to be charged by Metropolitan for water it
refuses to serve to SDCWA; at a minimum, a price adjustment should be implemented.
SDCWA is committed to taking all steps necessary to resolve these critical issues with
Metropolitan. However, until current policies are changed, short-term reliability is low.

Long-Term Reliability
Regional long-term reliability have been beneficially impacted by the implementation of
major storage facilities by both MWD and SDCWA. These facilities provide emergency storage
sufficient to handle their respective service area needs with major aqueduct outages for as long
as six months. In addition, other facilities planned by each agency will add to the overall system
reliability through redundancy and system enhancements.
With regard to resource reliability, which is the primary issue during an extended drought,
continued implementation of recycled water, groundwater recovery, conservation, groundwater
storage and conjunctive use programs by both MWD and SDCWA will enhance the region’s
ability to reduce dependency on imported supplies during extended drought periods. However,
these sources alone are not sufficient to meet imported water needs. Other sources of imported
water, such as the SDCWA-Imperial Irrigation District water transfer and seawater desalination,
are necessary to meet our long-term water needs.
Frequency and Magnitude of Supply Deficiencies
average rainfall years through 2020. According to SDCWA, if projected imported and local
supplies are developed as indicated, no shortages are anticipated within the Authority’s service
area in the dry-year scenarios analyzed. No extraordinary conservation measures, beyond the
implementation water conservation best management practices, are reflected in the dry-year
scenarios.
The San Diego County Water Authority does not anticipate any water shortages in any
Plans to Assure a Reliable Water Supply
SDCWA does recognize the uncertainties regarding imported water supplies from MWD
and is taking steps to reduce this dependency through water transfers and the development of
local projects (including demand management).
In addition, CMWD is continuing to study local water resource programs such as
recycling and seawater desalination to improve supply reliability during droughts (see Water
Sources (Supply)).
Three-Year Minimum Water Supply
The data in Table 4-1 shows the minimum water supply available to CMWD in the next three
water years. The anticipated dry-year supply in 201 0 was used for the single dry-year analysis in
order to show the results of local and imported water supply development over the next ten
years. If projected imported and local supplies are developed as indicated, no shortages are
anticipated within the CMWD service area in the dry-year scenarios analyzed.

Transfer or Exchange Opportunities
Law
1063 1. A plan shall be adopted in accordance with this chapter and shall do all
of the following:
10631 (d) Describe the opportunities for exchanges or transfers of water on a
short-term or long-term basis.
Water Transfers
As discussed earlier, CMWD relies entirely on imported water from the San Diego
County Water Authority. SDCWA has found that water transfers provide great potential for
meeting future regional demands. Water transfers are typically defined as the purchase of water
during a specified period from an agency or district that then reduces its water use by that amount.
In 1998, the SDCWA signed a historic agreement with the Imperial Irrigation District (IID) for the
long-term transfer of conserved Colorado River water to San Diego County. The SDCWA-IID
Water Conservation and Transfer Agreement will increase the reliability of the Authority‘s future
imported water supplies.
On Oct. 16, 2003, officials from the San Diego County Water Authority, Imperial Irrigation
District, Coachella Valley Water District and the Metropolitan Water District of Southern
California joined the governor of California and the U.S. Secretary of the Interior for the QSA
signing ceremony at Hoover Dam.
This historic agreement provides California with a transition period to implement water
transfers and supply programs that will reduce California’s overdependence upon the Colorado
River and reduce the state’s draw to its 4.4 million acre-foot basic annual apportionment. The
QSA commits the state to a restoration path for the environmentally sensitive Salton Sea and
provides full mitigation for these water supply programs. The QSA assures California up to 75
years of stability in its Colorado River water supplies.
23 3 7
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
SDCWA-IID Water Conservation and Transfer Agreement
Two water transfer agreements, finalized in October 2003, will provide an additional
277,700 acre-feet of water annually to the San Diego region. The San Diego County Water
Authority-Imperial Irrigation District water transfer will provide 200,000 acre-feet of water a year
through water conservation measures in Imperial Valley. The transfer is the cornerstone of the
Colorado River Quantification Settlement Agreement, a broader plan that reduces California's
use of Colorado River water to its basic annual apportionment of 4.4 million acre-feet.
The SDCWA, IID, Metropolitan Water District of Southern California and Coachella
Valley Water District signed the QSA on Oct. 10, 2003. The transfer is in its third year of
implementation with 30,000 acre-feet of water transferred to San Diego in 2005.
Also included in the QSA is a project to conserve water from lining portions of the
earthen All-American and Coachella canals. The SDCWA has taken the lead on these canal-
lining projects that will yield 77,700 acre-feet of water annually for 11 0 years for San Diego
County.
SDCWA-Metropolitan Water Exchange Agreement
Colorado River to San Diego County. To satisfy this contingency, SDCWA entered into a water
exchange agreement with Metropolitan on November 1998. Under the exchange agreement,
Metropolitan will take delivery of the transfer water through its Colorado River Aqueduct. SDCWA
will pay Metropolitan a delivery fee. In exchange, Metropolitan will deliver to SDCWA a like quantity
and quality of water. The duration of the agreement is 30 years.
The exchange agreement calls for SDCWA to pay Metropolitan a per-acre-foot delivery fee
of $90 in the first 20 years, and $80/AF from years 21 through 30. Both figures would escalate
each year based upon an agreed-to rate of 1.55 percent for the first 20 years and 1.44 percent for
the final 10 years of the agreement. The financial terms of the agreement could be adjusted in the
loth and 20th years to address impacts of potential catastrophes and changes in regulatory
requirements. In addition to the contingencies of the SDCWA-IID agreement, there are conditions
associated with SDCWA-Metropolitan agreement that will need to be satisfied before deliveries
can be made. Table 4-2 shows the conditions along with status and estimated completion date.
A contingency of the transfer agreement was securing transportation of the water from the

The Department of Interior released a draft EIS in July 2000 comparing several surplus operating criteria alternatives. The seven basin states have since reached agreement on surplus criteria guidelines and the DO1 has accepted the proposal as public comment on the draft EIS.
A California law passed, providing $235 million in state
funding for the canal lining and storage projects.

ALL-AMERICAN CANAL AND COACHELLA CANAL LINING PROJECTS
As part of the QSA and related contracts, the Water Authority was assigned
Metropolitan's rights to 77,700 AFNR of conserved water from projects that will line the All-
American Canal (AAC) and Coachella Canal (CC). (See Figure 4-1) The projects will reduce the
loss of water that currently occurs through seepage, and the conserved water will be delivered to
the Water Authority. This conserved water will provide the San Diego region with an additional
8.5 million acre-feet over the 1 IO-year life of the agreement.

Other Sources Of imported Water
are not sufficient to meet the imported water needs of the region. Therefore, SDCWA must
pursue additional supplies, either local and/or imported. Potential imported sources include
various types of water transfers and/or Metropolitan non-firm supplies that may be available to
SDCWA.
Other Transfers
Supplies from the IID water transfer and SDCWA’s preferential rights from Metropolitan
There is the potential to obtain additional transfer supplies, beyond the IID transfer, to meet
the future demands of the San Diego region. There are various types of transfers available that are
typically categorized into the following types:
Core Transfers - Core transfers make water available through multi-year contracts that
convey a specific amount of water to the purchaser each year. The IID water transfer is
defined as a core transfer.
Spot Transfers - Spot transfers make water available for a limited duration (typically one
year or less) through a contract entered into in the same year that the water is delivered.
Option Transfers - Option transfers are multi-year contracts that allow the purchaser to
obtain a specified quantity of water at some future date. They usually require a minimum
payment for water even if the water is not needed. For example, an agreement may require
water to be purchased one out of every five years.
Storaqe Transfers - Storage transfers allow the purchaser to place water into storage for
delivery at some time in the future.
Water Exchanqes - Water exchanges are agreements between the purchasing agency and
selling agency that allow for the exchange of water from one source for water from a
different source.
The IID transfer supply is conserved water from the Colorado River. The other two
geographic regions where transfer water is currently available are central and northern
California. Transfers from northern and central California would utilize State Water Project
conveyance capacity. One example for how such transfers could be made available is the State
Water Bank created during the end of the recent drought. In 1991, as a drought emergency
measure, DWR created the bank to enable water-short districts and agencies to purchase
supplies from willing water sellers. DWR purchased the water supplies primarily from northern
California agricultural entities and sold these supplies to entities experiencing drought shortages.
DWR purchased the water for $125/AF and sold it for $175/AF (1991 costs). Metropolitan
* 26
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
purchased 21 5,000 AF in 1991 ; SDCWA, due to cutbacks in supply from Metropolitan, had to
separately purchase 2 1,600 AF through Metropolitan.
Under the recently adopted CALFED Bay-Delta Framework, a Water Transfers Program
will be initiated whose goal is to “...encourage the development of a more effective water
transfer market that facilitates water transfers and streamlines the approval process while
protecting water rights, environmental conditions, and local economic interests.” This effort will
assist agencies, such as SDCWA, in implementing water transfers from northern and central
California.
Additional transfer supplies for the San Diego region would not only help meet demands
but could also provide lower salinity water for purposes of blending with IID transfer water. Water
lower in TDS is required to blend with the higher TDS Colorado River water that will be supplied by
IID in order to achieve a lower overall TDS in SDCWA’s supplies.
In 1998, SDCWA’s Board of Directors authorized staff to prepare and distribute a request
for proposal (RFP) for additional transfers. SDCWA has explored and will continue to explore
transfer and water storage opportunities throughout California that have the potential to provide
a reliable imported water supply to help meet the region’s supplemental water needs. However,
all such programs are dependent on obtaining access to the water conveyance facilities
operated by Metropolitan. SDCWA is taking all steps necessary to obtain access to those
facilities on a fair and equitable basis.

Chapter 5 - Water Use Provisions
Law
1063 1. A plan shall be adopted in accordance with this chapter and shall do all
of the following:
1063 1 (e) (1) Quantify, to the extent records are available, past and current water
use, over the same five-year increments described in subdivision (a), and
projected water use, identifying the uses among water use sectors including, but
not necessarily limited to, all of the following uses:
(A) Single-family residential; (B) Multifamily; (C) Commercial; (D) Industrial;
(E) Institutional and governmental; (F) Landscape; (G) Sales to other agencies;
(H) Saline water intrusion barriers, groundwater recharge, or conjunctive use, or
any combination thereof; and (I) Agricultural.
(2) The water use projections shall be in the same 5-year increments to 20 years
or as far as data is available.
Past, Current and Projected Water Use
Water use in the CMWD service area is closely linked to the local economy, population,
and weather. Over the last half century a prosperous local economy has stimulated population
growth, which in turn produced a relatively steady increase in water demand. However, fluctuating
economic and weather conditions in the 1990s and lingering effects from the 1987-1 992 drought
resulted in deviations from historic demand patterns. By 1999 a new combination of natural
population increase and job creation surfaced as the primary drivers of long-term water
consumption increases.
Past, current and projected water use in the CMWD service area as well as the number
of service connections are divided into seven categories: single-family residential, multi-family
residential, commercial/industriaI, institutional, irrigation, agriculture and recycled water (see
Tables 5-1 and 5-2).

Residential water consumption is composed of both indoor and outdoor uses. Indoor
water use includes sanitation, bathing, laundry, cooking and drinking. Most outdoor water use is
to meet landscaping irrigation requirements. Other minor outdoor uses include car washing,
surface cleaning, and similar activities. For single-family residences in Carlsbad, outdoor
demands are as high as 60 percent of total water use.
Carlsbad’s housing stock composition in 2004 was 68 percent single-family homes,
29percent multi-family homes, and 3 percent mobile homes. Single-family residences generally
contain larger landscaped areas, predominantly planted in turf, and require more water for
outdoor application in comparison to other types of housing. The general characteristics of multi-
family and mobile homes limit outdoor landscaping and water use, although some condominium
and apartment developments do contain green belt areas.

CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
Commercial/lndustriaI/lnstitutional Sectors
Commercial water demands consists of generally incidental uses but are necessary for
the operation of a business or institution, such as drinking, sanitation and landscape irrigation.
Major commercial water users include service industries such a restaurants, car washes,
laundries and hotels. Statistics indicate that almost 60 percent of Carlsbad’s employment base is
in the commercial sector.
Industrial water consumption consists of a wide range of uses, including product
processing and small-scale equipment cooling, sanitation and air conditioning. Water-intensive
industrial uses in Carlsbad, such as electronics manufacturing and biotech research, typically
require smaller amounts of water when compared to other water-intensive industries found
elsewhere in Southern California, such as petroleum refineries, chemical processors, and
canneries.
Institutional water use consists primarily of schools and churches within the service area.
Water use characteristics tend to be similar to commercial uses but based on average daily
attendance. Outdoor use also tends to be somewhat higher for landscaped areas and ball fields.
However, many of these areas tend to be metered separately and categorized as irrigation.
The tourism industry in Carlsbad affects water usage by not only the number of visitors,
but also through the expansion of service industries and attractions, which tend to be larger
outdoor water users. Tourism is primarily concentrated in the summer months and affects
seasonal demand and peaking. Population forecasts do not specifically account for tourism, but
tourism is reflected in the economic forecasts and causes per capita use to increase.
Irrigation Sector
Just ahead of commercial water use, irrigation is the second largest water use in the CMWD
service area. Carlsbad’s development over the last decade and a half has brought about the
creation of large amount of irrigated areas with various uses, including medians, slopes,
parkways and parkways. In 2005, seasonal fluctuations range from 16 percent of total demand
in February to over 25 percent in the month of August.
The effects of seasonal differences will have an obvious influence on irrigation demands.
The City of Carlsbad adopted a Landscape Manual in 1990 to assist development
applicants and landscape architects in understanding the City’s policies toward landscaping.
Specifically, the manual requires that irrigation systems be designed to provide the optimum
amount of water for plant growth without causing soil erosion or runoff. At the same time, the
document requires that landscape design will include water conservation and alternative (non-
potable) water sources as primary criteria.
30
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
Agricultural Sector
Agricultural water use has been decreasing in Carlsbad for the last two decades. In
1982, this sector accounted for over 32 percent of total water demands. In 2005, this figure
averaged only 5.5 percent.
This sector experiences wide seasonal fluctuations due to weather conditions and timing
of the growing seasons. In March, agriculture accounts for 2.8 percent of total consumption in
comparison to 6 percent in August.
Recycled Water Sector
customers to water golf courses, median strips and other landscaped areas. Overall, recycled
water use represents almost 10 percent of total water use in the CMWD service area. As in
other sectors, wide seasonal fluctuations occur with recycled water use. In March 2004, recycled
water represented only 2 percent of total water use, while the following June, it represented
almost 13 percent. Recycled water use tends to be lower in the winter months to avoid potential
runoff into lagoons and the ocean during rainy weather.
In 2004, CMWD sold 1,761 acre-feet of recycled water. This water was used by irrigation
The Carlsbad Municipal Water District adopted a Recycled Water Master Plan in 1990,
which was updated in 1997. This Master Plan identifies CMWD service area to be served in
several phases. The District is currently concluding development of Phase II. The Master Plan
covers the development of recycled water systems throughout Carlsbad until buildout.

Table 6-1 compares current, and projected water supply and demand. It indicates that in
average precipitation years, the Carlsbad Municipal Water District has sufficient water to meet its
customers’ needs, through 2020. This is based on continued commitment to conservation
programs, additional recycled water becoming available, development of either desalinated
groundwater or seawater, and SDCWA’s efforts to reduce our dependence on imported water
supplies from MWD. A breakdown of historic and projected demands is shown in Table 5-1 on

is highly dependent on SDCWA and MWD to meet its needs during dry years. Fortunately,
SDCWA does not anticipate any water shortages in the dry-year scenarios analyzed.
Studies have shown that hot, dry weather may generate urban water demands that are
about 7 percent greater than normal and agricultural demands that are about 9 percent greater
than normal. These percentages were used to generate the dry year demands shown in Table 6-
2. No extraordinary conservation measures, beyond BMP implementation, are reflected in the
demand projections. The additional supplies necessary to meet future demands in dry years will
be obtained by SDCWA through the development of transfers and the purchase of other
supplies from MWD, as discussed in Chapter 3, and by CMWD through local water resource
programs, such as recycling and seawater desalination.

Law
10631 (f) Provide a description of the supplier’s water demand management
measures. This description shall include all of the following:
(1) A description of each water demand management measure that is currently
being implemented, or scheduled for implementation, including the steps
necessary to implement any proposed measures, including, but not limited to, all
of the following.. .
Demand management, or water conservation, is frequently the lowest-cost resource
available to a water agency, and is a critical part of CMWD’s long-term strategy for meeting its
water supply needs. The goals of our water conservation program are to reduce demand for
more expensive, imported water, demonstrate continued commitment to the Best Management
Practices (BMP’s) and to ensure a reliable future water supply.
Best Management Practices
The California Urban Water Conservation Council (CUWCC) was formed in 1991
through a Memorandum of Understanding Regarding Urban Water Conservation in California
(MOU). The urban water conservation practices, or BMP’s, included in this MOU are intended to
reduce California’s long-term urban water demands.
CMWD is not yet a signatory to the MOU and is therefore not a member of CUWCC. The
District‘s Board of Directors will vote on the issue of becoming a member of the CUWCC and a
signatory to the MOU in 2005,as a part of this UWMP update. However, as a retail agency,
CMWD is committed to the implementation of the BMP’s. Table 7-1 provides an overview of
CMWD’s progress in the implementation of the recently updated BMP’s as outlined by the
cuwcc.

CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
BMP 3 -- Distribution System Water Audits, Leak Detection and Repair
CMWD reviews monthly water production records and compares the amount of water produced
against the monthly-billed consumption records to determine the amount of unaccounted for water. District
employees routinely drive water transmission line routes to visually look for water leaks. In addition, CMWD
has an aggressive meter exchange program where older, less accurate water meters are exchanged for new,
accurate ones. As a result, CMWD’s annual water loss percentage has averaged about 5 percent for the
past five years.
BMP 4 -- Metering with Commodity Rates
Metering of all water use and billing by volume has long been the standard practice of the
District.
BMP 5 -- Large Landscape Programs and Incentives
CMWD’s Water Conservation Specialist has been trained to conduct landscape water
audits with in-house equipment and software and has been doing so since 1991. In addition,
since 1990, the District has participated in SDCWA’s contractor-operated large landscape
program for landscapes greater than 1 acre. This program provides a thorough survey of the
irrigation system, soils and plant materials, and calculates an irrigation schedule based upon

Chapter 8 -Water Shortage Contingency Plan
Law
10632. The plan shall provide an urban water shortage contingency analysis
which includes each of the following elements which are within the authority of
the urban water supplier.. .
10632 (c) Actions to be undertaken by the urban water supplier to prepare for,
and implement during, a catastrophic interruption of water supplies including,
but not limited to, a regional power outage, an earthquake, or other disaster.
The effective management of water supply shortages is an important responsibility of
water agencies in Southern California. Shortages may be caused by droughts, failures of major
water transmission facilities during earthquakes, an acute contamination of supplies due to
chemical spills, or other adverse conditions.
The need for an effective management program to mitigate water supply shortages
arises from CMWD’s experiences during the drought in the early 1990’s. The current approach
to managing water shortages has evolved from these drought experiences.
In February 1992 the CMWD Board of Directors adopted the Urban Water Shortage
Contingency Plan in accordance with State law. CMWD refers to this plan as an operational
guideline in the event of a severe water shortage. As part of the Shortage Contingency Plan,
CMWD adopted Ordinance No. 35, An Ordinance ofthe Carlsbad Municipal Water District
Finding the Necessity For and Adopting a Water Conservation Program. This ordinance outlines
water conservation stages during normal periods and periods of water shortages.
As a member agency, CMWD is included as part of the San Diego County Water
Authority’s Emergency Response Plan and Emergency Storage Project, both developed in order
to protect public health and safety and to limit economic damage that could occur from a severe
shortage of water supplies. See the San Diego County Water Authority’s Urban Water
Management Plan 2005 for more information on these topics.

Water Shortage Contingency Plan
Law
10632. The plan shall provide an urban water shortage contingency analysis
which includes each of the following elements which are within the authority of
the urban water supplier:
10632 (a) Stages of action to be undertaken by the urban water supplier in
response to water supply shortages, including up to a 50 percent reduction in
water supply and an outline of specific water supply conditions which are
applicable to each stage.
10632 (d) Additional, mandatory prohibitions against specific water use
practices during water shortages, including, but not limited to, prohibiting the
use of potable water for street cleaning.
10632 (e) Consumption reduction methods in the most restrictive stages. Each
urban water supplier may use any type of consumption reduction methods in its
water shortage contingency analysis that would reduce water use, are appropriate
for its area, and have the ability to achieve a water use reduction consistent with
up to a 50 percent reduction in water supply.
10632 (0 Penalties or charges for excessive use, where applicable.
10632 (h) A draft water shortage contingency resolution or ordinance.
10632 (i) A mechanism for determining actual reductions in water use pursuant
to the urban water shortage contingency analysis.
The District's Board of Directors adopted an ordinance adopting a water conservation
program in 1991 (see Appendix B for complete text of the ordinance). This ordinance outlines six
stages of water alerts that describe different required conservation savings, as shown in Table
8-1. These conservation savings range from voluntary compliance with reasonable conservation
efforts in Stage 1 to a mandatory 40 percent reduction in Stage 6. For a water emergency
requiring 50 percent reduction in water use, the CMWD falls under SDCWA policy. Enforcement
and penalties for violations of the mandated restrictions are noted in Section 7 of the ordinance.
Emergency response stage actions become effective when SDCWA declares that it is
unable to provide sufficient water supplies to meet the ordinary demands and requirements of its
member agencies without depleting available water supplies, to the extent that insufficient water
would be available for human consumption, sanitation and fire protection. When SDCWA
announces its stage declaration, CMWD concurrently would declare its corresponding stage.

Revenue and Expenditure Impacts/Measures to Overcome Impacts
Law
10632. The plan shall provide an urban water shortage contingency analysis
which includes each of the following elements which are within the authority of
the urban water supplier:
10632 (g) An analysis of the impacts of each of the actions and conditions
described in subdivisions (a) to (0, inclusive, on the revenues and expenditures
of the urban water supplier.. .
10632 (g) [An analysis of the impacts of each of the] proposed measures to
overcome those [revenue and expenditure] impacts, such as the development of
reserves and rate adjustments.
Prior to the implementation of the CMWD’s new rate structure in July, 1996, CMWD
derived 83 percent of its revenue from commodity charges. This heavy reliance on variable
revenue left the CMWD vulnerable to fluctuations in water sales. The new rate structure
lessened our reliance on variable charges and shifted revenues to fixed sources such as the
monthly delivery charge.
In the event that revenues are less than required to meet the District’s financial
obligations, a reserve fund has been established. Prudent fiscal management requires that
reserve funds be established and maintained at adequate levels to provide short-term capital in
case of emergencies. The CMWD’s operating reserves represent approximately 40 percent of
annual operating expenses. This balance is necessary because of our dependence on SDCWA
and MWD for our water supply.
In the event of a water emergency, Ordinance No. 35 would be activated to respond to
the level of shortage. At that time, drought response stage actions would go into effect and the
CMWD would be operating with reduced water sales. The amount of decreased revenue would
depend upon the response stage under which the CMWD would operate.

Wastewater System Description
The sewer service area covered by the Carlsbad Municipal Water District includes the
majority of the City of Carlsbad’s boundary, with the exception of the southeast corner of the city
(see map on page 43). The estimated year 2005 sewer service population is 61,850 versus a
total City population estimated at 95,146.
Within its service area, CMWD is responsible for wastewater collection and conveyance
to the Encina Water Pollution Control Facility (EWPCF), located in Carlsbad. EWPCF also treats
wastewater from other municipalities, including San Marcos, Vista and parts of Encinitas. The
facility provides for full secondary treatment, sludge handling and disposal through a deep ocean
outfall that extends along the ocean floor to a point 1.5 miles off shore, at a depth of over 150
feet. The treatment levels meet all current State and Federal requirements.
The present capacity of EWPCF is approximately 36 mgd. This capacity is owned by six
member agencies that make up the Encina Wastewater Authority (EWA). The City of Carlsbad
owns capacity rights for 9.24 mgd. Currently, CMWD collects and transports an average of 6.05
mgd (see Table 9-1 for wastewater generation projections to 2020).

sites served by recycled water include La Costa Resort and Spa, Four Seasons Resort at
Aviara, Legoland of California, Grand Pacific Palisades Hotel, Karl Strauss Brewery and the
world renowned Flower Fields. While these are the most recognized sites being supplied with
recycled water, it is also supplied to parks, median strips, shopping areas, freeway landscaping
and the common areas of numerous homeowners associations.
The City of Carlsbad has approximately 80 miles of recycled distribution pipeline (see
Recycled water is presently supplied to Carlsbad from two sources: the Meadowlark
Treatment Plant, owned and operated by the Vallecitos Water District, and the Gafner Treatment
Plant, owned and operated by the Leucadia County Water District. These two plants produce
approximately 3.00 million gallons per day of tertiary treated, disinfected recycled water. As more
recycled water projects come on-line, more recycled water will be available. Within the next three
to five years, the amount of recycled water available to the public will increase by approximately
6 million gallons per day. Table 9-2 projects recycled water capacity to 2020 for the Phase II and
Ultimate systems.

Potential Uses of Recycled WatedTechnicaI and Economic Feasibility Analysis
Potential recycled water markets are locations where recycled water could replace
potable water use. These potential markets are typically landscape or agricultural irrigation
systems, or possibly industrial water users. This section discusses previous market
assessments and current customer assessment including the results of an irrigation meter
survey within the District, and recommended service areas for Phase II of the recycled water
distribution system, as well as the ultimate system.
Previous Assessments
In 1990, the Cadsbad Reclaimed Water Master Plan identified market types and then
researched potential recycled water markets using past studies, water meter records, irrigation
meter records, and assistance from the City’s planning department. Market types included the
following: agricultural, golf course, freeway, land development and park irrigation; industrial and
commercial uses; groundwater recharge and lagoon and stream enhancement. Specific
potential customers were listed, along with an estimate of recycled water use at that site.
Potential markets identified in the 1990 Master Plan were primarily sites requiring
landscape irrigation. Approximately 6,000 AFY was projected for potential recycled water
irrigation in 1995, and approximately 10,700 AFY was projected for 201 5. Stream and lagoon
enhancement and groundwater recharge were not considered to be viable projects in the 1990
Master Plan.
The 1997 Master Plan Update reviewed the previous assessment of potential recycled
water markets. Planned land development had changed in some areas of Carlsbad; some
markets identified in the 1990 Master Plan had been changed to designated open space for
habitat management, and some potential markets no longer existed. However, the updated list
of potential recycled water markets included 208 sites throughout the City, including markets
outside of the District’s service area, and projected an ultimate irrigation use of approximately
11,000 AFY, within 2.8 percent of the 1990 Master Plan projection. No use of groundwater
recharge or stream/lagoon enhancement was addressed in the update, except for storage at
Lake Calavera.
46
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
Current Customer Assessment
To define the Phase I1 and Ultimate distribution systems, an updated look at potential
recycled water customers was required. Using the 1997 Master Plan Update list of potential and
existing markets as a basis for the current assessment; the information was evaluated for
accuracy. The District also provided current recycled irrigation meter records for existing Phase I
customers for evaluating average and peak month recycled water demands.
The District‘s preliminary financial analyses are based on recycled water sales of 5,000
AFY by the year 2008. Based on further financial analysis, it was determined that a recycled
water sale of 5,400 AFY is a more favorable goal and comfortably satisfies the SWRCB funding
criteria. In addition, the District is participating in MWD’s Local Resources Program (LRP), which
requires reliable and achievable demand projections. Furthermore, overestimating potential
demands, including peak usages, could result in oversized facilities and excessive capital cost.
Therefore, an irrigation meter record survey was conducted to better assess the recycled water
market and potential demand.
Irrigation Meter Record Survey.
The District had previously maintained an AutoCAD drawing of each potable water meter
location in its water system, which does not include the City area not served by CMWD. The
District updated this drawing and provided it in order to facilitate a detailed irrigation meter record
survey. These data were converted into Geographic Information System (GIS) coverages where
each irrigation meter was graphically linked to its unique account number. The District then
provided one year of potable irrigation records that was converted to an average annual demand
for every irrigation meter.
Approximately 850 irrigation meter accounts were surveyed from the GIS coverage and
linked database. The irrigation meters were then grouped into subareas throughout the District‘s
service area to determine where the largest potential demand areas were located. The software
program “ArcCAD” was utilized to intersect the subareas with the meter accounts to provide an
average annual demand for each subarea and a total District-wide demand.
In summary, the District currently serves approximately 3 mgd (3,300 AFY) of irrigation
demand using potable water. Thus, if sufficient recycled water supply is available, the District
could actually meet its Phase II goal by converting current irrigation services to the recycled
system. However, in many cases these demands are located a long distance from the existing
recycled system such that it is not cost effective to connect.
In reviewing the database, many irrigation meters serve a low annual demand that may
not be economical to convert from potable to recycled water. It is also possible that some
47 61
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
existing landscape areas may not wish to use recycled water due to stringent water quality
requirements. For example, despite recycled water being currently available at these
developments, irrigation meters at both Aviara and La Costa developments were connected to
the potable system, due possibly to water quality or other onsite requirements. Some flower
growers also require very high quality water that may only be achievable through further onsite
treatment of recycled water. For these reasons, it is recommended that the District design its
Phase II recycled water system to serve a potential demand of at least 10 to 15 percent over the
revenue goal of 5,400 AFY.
Comparison to Previous Assessments.
In reviewing the previous market assessments, several customers appeared to have
overestimated demands when compared to actual irrigation usage. For example, the potential
recycled water demand at the Olympic Resort and Hotel was previously estimated based on an
irrigated area of 130 acres. Based on existing potable irrigation records and site reconnaissance
(the irrigation is used for a driving range, not a golf course), the actual irrigated area appears to
be less than 10 acres, which correlates to the actual demand of approximately 15 AFY.
(Previous estimates were about 400 AFY.)
The Rancho Carlsbad Golf Course showed a low potable irrigation use for the
approximate 35-acre site. District staff confirmed that groundwater is used for onsite irrigation,
resulting in the current low potable demand. This user may be reluctant to convert to recycled
water use due to economics, presuming the cost to pump groundwater is much less than
recycled water costs. Because of the high potential demand (over 100 AFY), the District should
ultimately consider this site for recycled water. For study purposes, the market assessment
included this site, as an ultimate customer, with a demand of 100 AFY.
Summary of Key Findings.
It became apparent, based on the potable irrigation meter survey, that the following
subareas within the District provided significant potential recycled water demand:
Calavera Hills (100 AFY)
Carlsbad Research Center (1 25 AFY)
Homeowner Associations just east of Interstate 5 (1 00 AFY)
Carrillo Ranch (Continental Homes) (200 AFY)
District Office Area (150 AFY)
These areas were generally in close proximity to existing recycled pipelines or have
already been dual plumbed to accept recycled water. Thus, these areas became primary target
service areas for the Phase II distribution system. Those customers (typically residential
48 @-
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
developments) that were constructed after 1993 have been dual plumbed, as required by the
District. These potential recycled water customers are expected to be served as soon as
recycled water becomes available and should be a priority for designing the Phase II distribution
system. No significant retrofitting of these proposed customers is expected to be required.
Proposed Phase II Customers
To satisfy conditions of financial assistance from MWD’s LRP, the District is required to
sell approximately 5,400 acre feet per year of recycled water by 2008. The existing recycled
water system serves approximately 2,000 AFY (including La Costa Golf Course South, which
receives recycled water directly from Gafner); therefore, the Phase II distribution system must
reach enough customers to satisfy an additional recycled water demand of approximately 3,400
AFY. This equates to approximately 1,400 acres of irrigated landscape area assuming an
application rate of 2.5 AFY per acre.
To begin the Phase II market evaluation, the list of all potential recycled water customers
from the 1997 Master Plan Update was reviewed and updated. Projected demands were revised
for existing customers on the list that are now being served with potable water based on recent
irrigation meter data. A few additional customers were also added based on a review of recent
development plans.
water pipeline network and serve all potential recycled customers. This distribution system was
then optimized; creating a Phase II system that would meet the re-use goal with a minimum
number of new recycled water facilities. Investigating several different pipeline alternatives,
hydraulic computer simulations, and incorporating comments from City, District staff then refined
the proposed Phase II Recycled Water System.
Initially, a distribution system was proposed that would expand the existing recycled
The largest potential customers for the Phase II system are identified as follows:
Kelly Ranch (216 AFY)
Carlsbad Municipal Golf Course (385 AFY)
La Costa Residential Areas (170 AFY and 177 AFY, the Ridge and Oaks)
Green Valley (1 55 AFY).
Calavera Hills (additional 100 AFY)
These customers represent major land development projects under construction or
anticipated to be under construction over the next two years. These five largest users within the
Phase II system represent over 40 percent of the potential demand on the expanded distribution
system. Therefore, the financial success of the Phase II program will greatly depend on the full
development of these larger customers. In reviewing the potential Phase II customers, the
49
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
District also should focus on developing recycled water customer demands in excess of 50 AFY
in the early years of the Phase II program because they represent more than 75 percent of the
estimated potential demand.
Potential demand of approximately 900 AFY was included from the potable irrigation
meter survey. This demand represents irrigation meter locations along existing or proposed
Phase II recycled pipelines. It becomes apparent that multiple irrigation meters exist for the
same customer or site. By grouping those meters, Table 9-3 presents a summary of the larger
irrigation users currently being served by the potable system. Through grouping, these
customers become a high priority for conversion to recycled water.
Las Playas HOA

Phase II Summary of Large Potable Water Irrigation Customers

Ultimate Customers
The Ultimate System will serve over 22,000 AFY of recycled water in the year 2020. The
largest customers within the Ultimate System include the future Carlsbad Ranch Golf Course
(400 AFY), La Costa Residential areas (372 AFY), and the Carlsbad Oaks Industrial Park (228
AFY). Approximately 1,000 AFY of potable irrigation meters were identified as potential recycled
water customers.
Many of these water customers are ready to be connected to the recycled water system
now. However, due to Phase II pipeline routing economics, some of these customers are better
served in the Ultimate System. A few potential customers were also eliminated from the
distribution system due to their remote location, and associated high incremental cost of
connecting pipelines.

Encouraging Recycled Water Use
Law
10633. The plan shall provide, to the extent available, information on recycled
water and its potential for use as a water source in the service area of the urban
water supplier. To the extent practicable, the preparation of the plan shall be
coordinated with local water, wastewater, groundwater, and planning agencies
and shall include all of the following:
10633 (e) A description of actions, including financial incentives, which may be
taken to encourage the use of recycled water, and the projected results of these
actions in terms of acre-feet of recycled water used per year.
10633 (f) A plan for optimizing the use of recycled water in the supplier’s
service area, including actions to facilitate the installation of dual distribution
system and to promote recirculating uses.
Encouraging and optimizing recycled water use in the CMWD service area involves a
combination of financial incentives, city policies, staff assistance and training opportunities.
Financial Incentives
CMWD currently subsidizes the use of recycled water by giving recycled users a 5
percent discount off potable water rates. The current rate for recycled users is $1.52 per unit
(one unit = 748 gallons).
City Policies
It is the policy of the District that recycled water shall be used within the jurisdiction
wherever its use is economically justified, financially and technically feasible, and consistent with
legal requirements, preservation of public health, safety and welfare, and the environment. This
policy requires the District to prepare and adopt a Recycled Water Master Plan to define,
encourage and develop the use of recycled water, and to update this plan no less than every five
years.
Board (see Appendix C), requires that recycled water be used on all new land use developments
proposed in Carlsbad for all State-approved non-potable uses, if and when available. The
installation of dual irrigation systems and connections to recycled water sources is also required
and subject to the conditions of the District’s Recycled Water Master Plan.
City policy, as established in 1990 and recently revised and approved by the CMWD
Staff Assistance
CMWD has Cross Control Connection Technicians who review on-site irrigation systems
to verify no cross connections have occurred between the potable and recycled water systems.
51 14
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
In addition, reviews are made to eliminate overspray and nuisance problems. To date, no major
problems have occurred. A quarterly report is submitted to the San Diego Regional Water
Quality Control Board on any field tests and observations. For businesses, cross connection
tests are often performed at night to reduce impacts on their operations and customers.
User guidelines have been established by CMWD in conjunction with the San Diego
County Health Department, which are intended to provide the basic parameters for the use of
recycled water in landscape irrigation. These guidelines include:
1.
2.
3.
4.
5.
6.
7.
8.
Irrigation between the hours of 1O:OO p.m. and 6:OO a.m. only.
Irrigation in a manner that will minimize run-off, pooling and ponding.
Adjustment of spray heads to eliminate overspray onto areas not under the control of the
user.
Monitoring and maintenance of the system to minimize equipment and material failure.
Education of all maintenance personnel on a continuous basis as to the presence of
recycled water and for what purposes it is allowed to be used.
Prior approval by the District of all proposed changes and modifications to any private
facilities.
An annual cross connection inspection.
Designation of an on-site supervisor, in writing, who is familiar with the plumbing system,
basic concepts of backflowkross connection protection and the specific requirements of
a recycled water system.
Training
Each year, CMWD hosts a one-day certified course designed to provide irrigation
supervisors with a basic understanding of recycled water. The San Diego County Water
Authority sponsors this class. Completion of the Recycled Water Site Supervisor Training fulfills
the training requirement as mandated by regulatory authorities. The class provides information
to supervisors on the water recycling process, recycled water quality and safety issues, the
duties and responsibilities of the supervisor, landscape irrigation fundamentals, maintenance
and management, and cross connection control shut-down tests and inspections. Understanding
similarities and differences between recycled and potable water is important to the successful
operation of a recycled water system.

Necessity For and Adopting A Water Conservation Program
Section 1. Declaration of Policy. California Water Code Sections 375 et. seq. permit public
entities which supply water at retail to adopt and enforce a water conservation program to
reduce the quantity of water used by the people therein for the purpose of conserving the water
supplies of such public entity. The Board hereby establishes a comprehensive water
conservation program pursuant to California Water Code Sections 375 et seq., based upon the
need to conserve water supplies and to avoid or minimize the effects of any future shortage.
Section 2. Findings. The Board finds and determines that a water shortage could exist based
upon the occurrence of one or more of the following conditions:
(a)
(b)
A general water supply shortage due to increased demand or limited supplies.
Distribution or storage facilities of the Metropolitan Water District of Southern
California, the San Diego County Water Authority, the District, or other agencies
become temporarily or permanently inadequate.
The Board also finds and determines that the conditions prevailing in the San Diego
County area require that the water sources available be put to maximum beneficial use to the
extent to which they are capable, and that the waste or unreasonable use, or unreasonable
method of use, of water be prevented and that the conservation of such water be encouraged
with a view to the maximum reasonable and beneficial use thereof in the interest of the people of
the District and for the public welfare.
Section 3. Application. The provisions of this ordinance shall apply to all water served to
persons, customers, and property by the District.
Section 4. Authorization. The District General Manager, or a designated representative, is
hereby authorized and directed to implement the provisions of this ordinance. Additionally, the
General Manager, or designated representative is hereby authorized to make minor and limited
exceptions to prevent undue hardship or unreasonable restrictions, provided that water shall not

APPENDIX C
Ordinance No. 31
An Ordinance of the Carlsbad Municipal Water District Mandating Use
of Reclaimed Water
WHEREAS, the people of the state of California have a primary interest in the
development of facilities to reclaim water containing waste to supplement existing surface and
underground water supplies and to assist in meeting the future water requirements of the state;
and (California Water Code Section 13510); and
WHEREAS, conservation of all available water resources requires the maximum reuse
of wastewater for beneficial uses of water; and (Water Code Section 461); and
WHEREAS, continued use of potable water for irrigation of greenbelt areas may be an
unreasonable use of such water where reclaimed water is available;
NOW, THEREFORE, the District does hereby ordain:
Section 1: Findings
The state policies described above are in the best interest of the District. The majority of
jurisdictions in San Diego County have adopted measures to promote water reclamation. This
ordinance is necessary to protect the common water supply of the region which is vital to public
health and safety, and to prevent endangerment of public and private property. San Diego
County is highly dependent on limited imported water for domestic agricultural and industrial
uses. The reliability of the supply of imported water is uncertain. By developing and utilizing
reclaimed water, the need for additional imported water can be reduced. In light of these
circumstances, certain uses of potable water may be considered unreasonable or to constitute a
nuisance where reclaimed water is available or production of reclaimed water is unduly impaired.
Reclaimed water would be more readily available in seasons of drought when the supply of
potable water for nonessential uses may be uncertain.
Section 2: Water Reclamation Policy
It is the policy of the District that reclaimed water shall be used within the jurisdiction wherever its
use is economically justified, financially and technically feasible, and consistent with legal
requirements, preservation of public health, safety and welfare, and the environment.

CHAPTER 1. GENERAL DECLARATION AND POLICY
10610. This part shall be known and may be cited as the "Urban Water Management Planning
Act."
1061 0.2. (a) The Legislature finds and declares all of the following:
(1) The waters of the state are a limited and renewable resource subject to ever-
increasing demands.
(2) The conservation and efficient use of urban water supplies are of statewide
concern; however, the planning for that use and the implementation of those
plans can best be accomplished at the local level.
(3) A long-term, reliable supply of water is essential to protect the productivity of
California's businesses and economic climate.
(4) As part of its long-range planning activities, every urban water supplier should
make every effort to ensure the appropriate level of reliability in its water
service sufficient to meet the needs of its various categories of customers
during normal, dry, and multiple dry water years.
(5) Public health issues have been raised over a number of contaminants that
have been identified in certain local and imported water supplies.
(6) Implementing effective water management strategies, including groundwater
storage projects and recycled water projects, may require specific water
71
CARLSBAD MUNICIPAL WATER DISTRICT 2005 URBAN WATER MANAGEMENT PLAN
quality and salinity targets for meeting groundwater basins water quality
objectives and promoting beneficial use of recycled water.
(7) Water quality regulations are becoming an increasingly important factor in
water agencies' selection of raw water sources, treatment alternatives, and
modifications to existing treatment facilities.
(8) Changes in drinking water quality standards may also impact the usefulness
of water supplies and may ultimately impact supply reliability.
(9) The quality of source supplies can have a significant impact on water
management strategies and supply reliability.
(b) This part is intended to provide assistance to water agencies in carrying out their
long-term resource planning responsibilities to ensure adequate water supplies to
meet existing and future demands for water.
1061 0.4. The Legislature finds and declares that it is the policy of the state as follows:
(a) The management of urban water demands and efficient use of water shall be
actively pursued to protect both the people of the state and their water
resources.
(b) The management of urban water demands and efficient use of urban water
supplies shall be a guiding criterion in public decisions.
(c) Urban water suppliers shall be required to develop water management plans
to actively pursue the efficient use of available supplies.
