No. 797, requires urban water suppliers providing water for municipal purposes to more than
3,000 service connections or supplying more than 3,000 acre-feet of water annually,
conduct a public hearing prior to the adoption of an Urban Water Management Plan. The
purpose of the Urban Water Management Plan is to achieve conservation and efficient use
of water supplies. The proposed plan updates the City's 1995 Urban Water Management
Plan.
RECOMMENDATION
It is recommended that the City Council take the following actions:
1. Conduct a public hearing to accept and respond to public comments on the 2000 Urban
Water Management Plan; and
2. At the conclusion of the public hearing, adopt Resolution No. 04-90 adopting the 2000
Urban Water Management Plan.

INTRODUCTION
1.1 PURPOSE AND PLAN SUMMARY
An Urban Water Management Plan (UWMP) is for the purpose to achieve conservation
and efficient use of water supplies. The California Urban Water Management Planning
Act of 1983 (Act), as amended, requires urban water suppliers to develop an UWMP
every five years in the years ending in zero and five.
The legislature declared that the waters of the state are a limited and renewable resource
subject to ever increasing demands; that the conservation and efficient use of urban water
supplies are of statewide concern; however, implementation of plans is best accomplished
at the local level; that conservation and efficient use of water shall be actively pursued to
protect both the people of the state and their water resources; that conservation and
efficient use of urban water supplies shall be a guiding criterion in public decisions; and
that urban water suppliers shall be required to develop water management plans to
achieve conservation and efficient use.
The City's 2000 UWMP has been prepared in compliance with the requirements of the
Act, as amended (Appendix A) t, and includes the following:

1.2 URBAN WATER MANAGEMENT PLAN UPDATE PREPARATION
The 2000 UWMP revises the 1995 UWMP prepared by the City of Tustin Water Service
(TWS) under the tenus of AB 797 (1983) and subsequent amending legislation.
The 2000 UWMP incorporates changes required by other legislation including AB 1845
(1995) and SB 1011 (1995). TWS has also included requirements of SB 610 (2001) and
SB 901 (2001) to integrate the latest urban water management planning directives.
Additionally, the UWMP incorporates water use efficiency efforts that TWS has
¡California Water Code, Division 6, Part 2.6; § 106 10, et. seq. Established by Assembly Bill 797 (1983).

implemented or is considering implementing pursuant to the Memorandum of
Understanding Regarding Urban Water Conservation in California (MOU).2
TWS is a contractor of imported water from East Orange County Water District
(EOCWD), which subcontracts through the Municipal Water District of Orange County
(MWDOC), which subsequently is a member agency of the Metropolitan Water District
of Southern California (Metropolitan). Since TWS is not a MOU signatory, MWDOC
implements many of the Best Management Practices (BMPs) on behalf of TWS.3
The sections in this UWMP correspond to the outline of the Act, specifically Article 2,
Contents of Plans, Sections 10631, 10632, and 10633. The sequence used to present the
required information, however, differs slightly in order to present the material in a
manner reflecting the unique characteristics of TWS.
Agency Coordination
The development of this UWMP was prepared through TWS and through coordination
with EOCWD and MWDOC for imported water, as well as the Orange County Water
District (OCWD), which manages the Orange County groundwater basin, and the Orange
County Sanitation District (OCSD), which manages wastewater. References that were
utilized as supplemental information are included within Appendix B.
UWMP Adoption
The 2000 UWMP was adopted by resolution of the Tustin City Council on -
following a public hearing. The UWMP was submitted to the California Department of
Water Resources within. days of Council approval. Copies of the notice of public
hearing and the Resolution of UWMP Adoption are included in Appendix C. Copies of
the UWMP were made available to the public within 30 days following Council approval.
The UWMP will be used by TWS staff to guide water use efficiency efforts through the
year 2005.
'The Memorandum of Understanding Regarding Urban Water Conservation in California (MOU) was
adopted in September 1991 by numerous water suppliers, public advocacy organizations and other
interested groups. It created the California Urban Water Conservation Council and established 14 Best
Management Practices (BMPs) for urban water conservation. recently refined to 14 BMPs. MWDOC is
signatory to the MOU and implements the BMPs on behalf of the City of Tustin. MWDOC became
signatory to the MOU in 1991.

WATER SERVICE AREA
Location
TWS provides potable water service to most of the incorporated area of the City and also
to unincorporated county areas north of the City. TWS is located in central east Orange
County as shown in Figure 1.1. TWS is bounded by the City of Orange to the north, the
City of Santa Ana to the west, the City of Irvine to the south, and unincorporated areas of
Orange County to the east. TWS is approximately 35 miles south of Los Angeles and 10
miles inland from the Pacific Ocean. TWS has an area of 8.4 square miles and an average
elevation of 130 feet above sea level. The topography of the City combines generally flat
areas with gradual rolling hills.
TWS is located along the Santa Ana Freeway (I 5), which provides access to the Costa
Mesa Freeway (SR 55), the Garden Grove Freeway (SR 22), the SR 133, and the San
Diego Freeway (I 405).
Climate Characteristics
TWS is located in an area known as the South Coast Air Basin (SCAB). The SCAB
climate is characterized by what is known as Southern California's "Mediterranean"
climate; a semi-arid environment with mild winters, wann summers and moderate
rainfall. The general region lies in the semi-pennanent high pressure zone of the eastern
Pacific. As a result, the climate is mild, tempered by cool sea breezes. The usually mild
climatologically pattern is interrupted infrequently by periods of extremely hot weather,
winter stonns, or Santa Ana winds.
The annual temperature varies throughout SCAB, averaging 75 degrees Fahrenheit.
January is usually the coldest month while July and August are usually the hottest months
of the year. Annual average relative humidity is 63.5 percent. Precipitation is typically
nine to fourteen inches, occurring mostly between November and April.
Demographics
TWS is predominantly residential with over 90 percent of water service connections
serving single-family or multi-family residences. Limited growth potential exists due to
minimum availability of open space.
The population of the TWS Service Area was 62,131 in 2000.4 The Center for
Demographic Research at California State University Fullerton projects minimal change
in the TWS population percentage and minimal change in land use over the next 20 years.
Table 1.1 shows the population projections in five-year increments to the year 2020. The
TWS population is projected to peak at 63,471 in 2005 with a gradual decrease in
subsequent years through 2020. The population decrease is associated with an aging
population, where the number of deaths is projected to exceed the number of births.

WATER SERVICE DIVISION AND FACILITIES
Water Service Division
TWS provides domestic and fire protection water service to most of the incorporated area
of the City of Tustin and also to unincorporated areas north of the City.
TWS receives approximately 85 percent of its water from underlying groundwater in the
Santa Ana River Basin. The remaining 15 percent is purchased imported water. TWS has
seven untreated or "clear" groundwater wells that pump directly into the distribution
system and two treatment facilities that treat groundwater from five additional wells.
The groundwater basin is managed by OCWD, who sets the percentage of groundwater
that an agency or city can pump based on their total potable water demand. For this
UWMP reporting period, the BPP for TWS is 75 percent.5 Production in excess of 75
percent of applicable demands is assessed under the Basin Equity Assessment (BEA)
with a production penalty, raising the cost of this supply to exceed imported water rates.
However, basin groundwater produced through treatment facilities is exempt from the
BEA since the treatment plants remove and use low quality water from the groundwater
basin, which would otherwise be unusable.
Imported water is purchased from Metropolitan through MWDOC and EOCWD.
Imported potable water delivered to EOCWD comes from the Diemer Filtration Plant
located north of Yorba Linda. Typically, the Diemer Filtration Plant receives a blend of
Colorado River water from Lake Mathews through the Metropolitan lower feeder and
State Water Project water through the Yorba Linda Feeder.
Water System Pressure Zones and Facilities
Elevations in the TWS service area range from 60 feet above mean sea level at Warner
and Redhill to 435 feet in the Lemon Heights area. The water system is divided into three
service pressure zones. The average ground elevations for Zones 1, 2, and 3 are 210 feet,
280 feet, and 400 feet above mean sea level, respectively.

WATER SUPPLIES
TWS receives approximately 85 percent of its water supply from the Orange County
Groundwater Basin and 15 percent imported supplies from Metropolitan through
EOCWD via MWDOC. These percentages reflect adjustments to the BPP for TWS's
participation in MWDOC and OCWD's In-lieu Program; where groundwater production
is reduced to allow available surface water to indirectly replenish the groundwater basin
through Metropolitan's seasonal storage program. This provides TWS an opportunity to
participate in enhanced basin management and replenishment programs operated by
MWDOC, OCWD and Metropolitan. The current projected water supplies and demand
are shown in Table 2.1.

WATER SOURCES
Groundwater
The Orange County Groundwater Basin (Basin) underlies the north half of Orange
County beneath broad lowlands. The Basin covers an area of approximately 350 square
miles, bordering the Coyote and Chino Hills to the north, the Santa Ana Mountains to the
northeast, the Pacific Ocean to the southwest, and terminates at the Orange County line to
the northwest; where its aquifer systems continue into the Central Basin of Los Angeles
County. The aquifers comprising the Basin extend over 2,000 feet deep and form a
complex series of interconnected sand and gravel deposits.

2000 Urban Water Management Plan Update
Section 2
The Basin generally operates as a reservoir in which the net amount of water stored is
increased in wet years to allow for manageable overdrafts in dry years. The Basin is
recharged primarily by four sources: 1) local rainfall, which varies due to the extent of
the annual seasonal precipitation; 2) base flow from the Santa Ana River; which includes
recycled wastewater from treatment plants in Riverside and San Bernardino Counties; 3)
imported water that percolates into the Basin; and 4) highly treated recycled wastewater,
which is directly recharged into the Basin. The production capability of the Basin has
increased as a result of increased wastewater reclamation and the blending of lower
quality water with potable water for public distribution.7
TWS has taken a proactive approach to increasing groundwater production. In the past,
the Basin underlying the TWS area was affected by years of excessive nitrogen usage
from farming and past and present use of septic sewerage systems, which has resulted in
high nitrate levels. Since 1996, TWS has developed new groundwater sources utilizing
two nitrate removal treatment plants, the Main Street Plant and 17th Street Desalter
Treatment Plant. Both treatment plants blend and treat groundwater high in nitrate levels:
to reduce nitrate concentrations in accordance with the California Department of Health
Services standards for safe drinking water. The withdrawal and treatment of this locally
developed supply is projected to enhance the Basin's water quality over time. Over the
past seven years, basin nitrate levels have declined significantly due to this treatment
program.8 In addition, the operation for nitrate blending has allowed TWS other fiscal
and operational benefits including a partial exemption for paying OCWD's BEA.
OCWD establishes the BPP each water year. The BPP is based on groundwater
conditions, availability of imported water supplies, and basin management objectives.
The BPP is a major factor in determining the cost of groundwater production and was set
at 75 percent for this UWMP reporting period.9 Groundwater production equal to or
lesser than the BPP pays a replenishment assessment (RA). If groundwater production
greater than the BPP occurs a BEA will be assessed. The BEA is an additional fee paid
on each acre feet (AF) of water pumped above the BPP, making the cost of that water
equal to the cost of imported water. Groundwater processed through the TWS' s treatment
plants is exempt from the BEA due to mitigation of nitrates and total dissolved solids
(TDS) removed from within the groundwater basin. This flexibility in producing over the
BPP affords TWS the ability to provide water to its customers during periods of varying
water availability.
TWS participates in the MWDOC and OCWD In-Lieu Storage Program when it is made
available. The In-Lieu Program allows TWS to receive Metropolitan water through the
local distribution system in place of pumping groundwater. The In-Lieu Program
indirectly replenishes the Basin by avoiding pumping. In the In-Lieu Program, OCWD
requests TWS to halt pumping from specified wells. TWS then takes replacement water
through its import connections, which is purchased by OCWD from Metropolitan

(through MWDOC and EOCWD). OCWD purchases the water at a reduced rate, and
then bills TWS the amount it would have had to pay for energy and the RA if it had
produced the water from its wells.
TWS currently has seven active clear groundwater wells as shown in Table 2.1. These
wells are categorized as clear groundwater wells even though several wells require
blending with either imported water or groundwater from another well in order to meet
the nitrate Maximum Contaminant Level (MCL). Blending is not considered a treatment
process by OCWD and blended groundwater is not exempt from the BEA.
TWS currently treats groundwater from five wells high in TDS and/or nitrates at the
Main Street Plant and 17th Street Desalter Treatment Plant as shown in Table 2.2.
Groundwater produced through these treatment plants removes TDS and nitrates from the
basin. As such, these wells are exempt from the BEA and are not included in BPP
calculations.

Imported Water Supply
TWS purchases approximately 15 percent of supplemental, treated, imported water from
EOCWD, which is a member agency of MWDOC, which subsequently is a member
agency of Metropolitan. Imported water purchases have decreased significantly in recent
years as a result of groundwater system treatment and production improvements.
Metropolitan imports raw water from northern California and the Colorado River, then
treats the majority of water to potable standards at filtration plants located in Southern
California.
Metropolitan water imported from northern California through the State Water Project
(SWP) is stored at Castaic Lake on the western side of the Metropolitan service area and
at Silverwood Lake near San Bernardino. Metropolitan water imported from the Colorado
River is stored at Lake Mathews in Riverside County. Metropolitan has recently
completed the construction of the Diamond Valley Lake Reservoir in Hemet, California;
an 800,000 AF capacity reservoir for regional seasonal and emergency storage for SWP
and Colorado River water. The reservoir began storing water in November 1999 and
reached the sustained water level by early 2002.
Imported potable water delivered to EOCWD comes from a single source, the Diemer
Filtration Plant, located north of Yorba Linda. Typically, the Diemer Filtration Plant
receives a blend of Colorado River water from Lake Mathews through the Metropolitan
lower feed and SWP water through the Yorba Linda Feeder. At this time, the blend is
approximately a 50/50 split between the two sources.
Reservoirs
Storage is required to balance variations in demand (operational or regulatory storage), to
provide water for fighting fire (fire storage), and to provide water when nonnal supplies
are reduced or unavailable due to unusual circumstances (emergency storage). The
existing storage system consists of six reservoirs with a combined storage capacity of
approximately 9.8 million gallons as shown in Table 2.3.

Recycled Water
TWS currently does not directly utilize recycled water for municipal uses or provides
service to any of its customers. TWS supports the efforts of the regional water
management agencies to utilize recycled water as a primary resource for groundwater
recharge in Orange County. These efforts also include recycling programs to irrigate
crops, golf courses, parks, schools, business landscapes, residential lawns, and cooling
systems within industrial sectors. In FY 1999/00, recycled water reuse totaled
approximately 35,178 AF in Orange County, which is nearly double the amount that was
used in 1989/90. Year 2020 projections equal a 108 percent increase in recycled water,
to nearly 62,850 AF. to
TWS's wastewater flows are directed to the OCSD for treatment. OCSD produces
recycled water year round for OCWD's Green Acres Project (GAP), which provides
recycled water for industrial customers and landscape irrigation in Fountain Valley, Santa
Ana, Costa Mesa, Newport Beach and Huntington Beach. The GAP distributes
approximately 7.5 million gallons per day (MGD) of tertiary treated water to irrigation
and industrial users. It also produces recycled water for OCWD's groundwater injection
system.
The Groundwater Replenishment (GWR) System is a OCWD/OCSD joint project, where
140,000 AFY of treated wastewater will be utilized to recharge the Orange County
Groundwater Basin, protect the Basin from further degradation due to seawater intrusion,
and augment the supply of recycled water for irrigation and industrial use. The GWR
System has been initiated in seven phases and is scheduled for completion by July

WATER QUALITY
3.1
WATER QUALITY OF EXISTING SOURCES OF WATER AVAILABLE
As required by the Safe Drinking Water Act, which was reauthorized in 1996, TWS
provides annual Water Quality Reports to its customers. This mandate is governed by the
Environmental Protection Agency (EPA) and the California Department of Health
Services (DHS) to ensure the safety of potable water.
TWS, OCWD, and Metropolitan vigilantly safeguard their water supplies through
continuous testing, monitoring, and processes for water quality. In some cases, TWS,
Metropolitan, and OCWD exceed DHS requirements and test for other contaminants that
have been known for health risks.
Local Supplies and Nitrate Testing
Standards for potable water quality include primary and secondary contaminant levels,
otherwise known as MCL. Primary MCLs are established for a number of organic and
inorganic chemicals, trihalomethanes, and radioactivity pertaining to public health.
Secondary MCLs are established for chemicals or characteristics pertaining to taste, odor,
and appearance.
TWS's groundwater meets State potable water quality standards with the exception of
nitrate and/or total dissolved solids (TDS) for some of the wells. The primary MCL for
nitrate is 45 mgll. The secondary MCL ran~e for TDS is 500 mgll (recommended), 1,000
mg/l (upper), and 1,500 mgll (short term). 2 As a primary MCL, nitrate is the principal
water quality concern for TWS. Nitrates are present in groundwater due to contamination
by decaying plant or animal material, manure, fertilizers, domestic sewage and/or
geological formations containing soluble nitrogen compounds. Groundwater high in
nitrate and TDS levels in TWS's service area is shown in Figure 3.1.
In order to mitigate high nitrate levels, TWS operates two groundwater treatment plants,
the Main Street Plant and 1711> Street Desalter Treatment Plant. The Main Street Plant
uses two separate processes. The plant is capable of treating groundwater to below the
nitrate MCL of 45 mgll through either reverse osmosis (RO) or ion exchange (IX). The
product water is blended with lower quality nitrate water from another well and is then
pumped into the distribution system, producing approximately 2,000 AFy.13

The 17th Street Desalter Treatment Plant utilizes only RO to treat water with excessive
concentrations of nitrates and TDS. This plant receives water from three different wells
and treats approximately 3,000 AFY.
Both treatment plants have been successful in lowering high nitrate water to achieve
compliance with the nitrate requirements. In the past several years there has been a
downward trend of nitrate concentrations in TWS wells. t4 TWS collects water samples
daily to ensure that nitrate levels do not exceed the recommended level of 45 mgll of
nitrate as NO3. The 1999 average was 23 mgll with a range of 16 to 28 mgll. t5
Groundwater
OCWD is responsible for managing and protecting the Orange County Groundwater
Basin. To ensure high water quality, OCWD's Board of Directors, adopted a
Groundwater Quality Protection Policy in 1987 aimed at protecting and improving the
basin's water quality supply. The policy includes water quality monitoring, cleanup of
contaminants, management of toxic and hazardous wastes, and sharing of information. In
addition, the Board established a $4.0 million toxic cleanup reserve account so that
immediate action can be taken for toxic spills. Overall, OCWD is committed to
maintaining the highest standards for water quality and has established a state of the art
laboratory testing facility and monitoring program.
Imported Water
TWS receives supplemental, imported water from Metropolitan through EOCWD and
MWDOC. Metropolitan receives raw water from northern California through the SWP
and the Colorado River Aqueduct (CRA). Imported potable water delivered to TWS
comes from a single source, the Diemer Filtration Plant. Typically, the Diemer Filtration
Plant receives a SO/50 blend of SWP and Colorado River water. t6
Metropolitan water is treated in accordance with potable standards at filtration plants
located throughout Southern California. Metropolitan tests and treats its water for
microbial, organic, inorganic, and radioactive contaminants as well as pesticides and
herbicides. Metropolitan is committed to ongoing water quality through tighter security
measures, persistent monitoring, community outreach for public awareness of safe
drinking water, and fluoride treated water to prevent tooth decay. t7

TWS has taken steps to insure an adequate and reliable water supply for the community.
Well and storage studies have been made by independent consulting engineering firms to
determine sufficient water supply and stringent water quality standards. Water
management strategies and supply reliability are in place to mitigate for population
growth and cyclic drought periods. TWS has consistently maintained standards for water
quality, thereby enhancing reliability at a local level. TWS will continue to seek
alternatives and modifications to improve existing facilities to obtain the highest quality

WATER RELIABILITY PLANNING
4.1
RELIABILITY OF WATER SUPPLIES FOR TUSTIN
All Orange County communities and water agencies, including TWS, are facing
increasing challenges in their role as stewards of water resources in the region. The
region faces a growing gap between its water demand and supply. Increased
environmental regulations and the collaborative competition for water from outside the
region have resulted in reduced supplies of imported water. Population and economic
growth in Orange County has increased water demand within the region, stressing the
local supplies.
MWDOC and OCWD are implementing water supply alternative strategies for the region
and on behalf of their member agencies to insure available water in the future. Strategies
are identified in the MWDOC 2000 Regional UWMP and the OCWD 2020 Master Plan
Report that identify the following objectives:
.
Ensure that the groundwater basin is protected.
Ensure that water is available for Orange County residents and businesses in the
future.
Minimize the consumer's water supply cost.
Use a variety of sources.
Reduce the salt balance in the groundwater basin.
Provide flexibility to allow both MWDOC and OCWD to quickly take advantage of
changing and new markets if and when they develop.

RELIABILITY COMPARISON
TWS's water usage is affected by numerous development changes, such as land use,
population, climatic factors, economic conditions, and demographic variables. Historical
water usage for TWS has been relatively constant over the past decade due to the area's
"built-out" nature, but deviations in water usage caused by cyclical weather variations are
evident.
Historical water use was utilized in conjunction with population forecasts to project
average demands for the planning period, year 2000 to year 2020. Water purchase and
production records and SCADA data were used to develop demands by service zone and
demand peaking factors. 18
Land use is not expected to change significantly in the next 20 years. However, some
development and redevelopment projects are expected to slightly increase the population
density of the service area through the year 2005 as shown in Table 4-1. The TWS

population is projected to peak at 63,471 in 2005 with a gradually decrease in subsequent
years through 2020. This population decrease is associated with an aging population,
where the number of deaths is projected to exceed the number of births between 2005 and
2020.
In the projected demand and supply comparison (Table 4.1), it is assumed that unusually
dry or wet years will average out and the basis of the projection will be assessed from a
historical water usage of 12,547 AF. Assuming that the average per capita water
consumption (199 gpcd) will remain fairly constant, and that although population
decreases, water demand would increase slightly due to the addition of service
connections from limited development and/or redevelopment. Section 5, Water Use
Provisions, presents additional water demand projections based on water use sectors.

OCWD has the authority to adjust the BPP annually based on groundwater conditions,
availability of imported water supplies, and basin management objectives to provide
water to its customers during periods of varying water availability. In addition, TWS has
an option to utilize basin groundwater produced through the treatment plants, to remove
low quality water from the groundwater basin.
In anyone dry year, OCWD would need to carefully manage its groundwater supply. In
multiple dry years, OCWD may temporarily increase the BPP to reduce the dependence
on Metropolitan supplies. The groundwater basin would be drawn down assuming the
seawater barrier was still effective. Following a drought, the BPP may be temporarily
decreased for a few years to more rapidly increase basin storage levels. However, a
constant BPP is more effective in managing water supply costs.
This analysis demonstrates that if imported water supplies were to be reduced due to a
water supply shortage, then groundwater production could be expected to increase along
with mandated water use efficiency measures to meet the demand for water.
4.3
VULNERABILITY OF SUPPLY FOR SEASONAL OR CLIMATIC
STORAGE
The City of Tustin lies in a semi-arid environment with mild winters, warm summers and
moderate rainfall. The general region lies in the semi-pennanent high-pressure zone of
the eastern Pacific. As a result, the climate is mild, tempered by cool sea breezes. The
usually mild climatological pattern is interrupted infrequently by periods of extremely hot
weather, winter stonns, or Santa Ana winds. The average annual temperature is 75
degrees Fahrenheit. July and August are usually the hottest months of the year.
Precipitation is typically 9-14 inches, occurring mostly between November and April.
Climatological data in California has been recorded since the year 1858. During the 20th
century, California has experienced three periods of severe drought: 1928-34, 1976-77
and 1987-91. The year 1977 is considered to be the driest year of record in the Four
Rivers Basin by the Department of Water Resources (DWR). These rivers flow into the
San Francisco Bay Delta and are the source of water for the State Water Project.
Southern California and, in particular, Orange County sustained few adverse impacts
from the 1976-77 drought. This was due in large part to the availability of Colorado River
water and groundwater stored in the Santa Ana basin. However, the 1987-91 drought
created considerably more concern for Southern California and Orange County.
As a result, the City is vulnerable to water shortages due to its climatic environment and
seasonally hot summer months. In the case of water shortages, TWS will adhere to water
use efficiency mandates of MWDOC and its support of the Metropolitan Water Surplus
and Drought Management Plan (WSDM Plan), along with implementation of the TWS
Water Shortage Contingency Plan.

ALTERNATIVE WATER SOURCES OR DEMAND MANAGEMENT
MEASURES
TWS projects that water demand will increase by 4.0 percent from 2000 to 2020.
Potentially, TWS could purchase all the water it needs to serve its customers from
Metropolitan through MWDOc. Any new water supply sources will be developed
primarily to better manage the Santa Ana Groundwater Basin resource and to replace or
upgrade inefficient wells, rather than to support population growth and new development.
4.5
MANAGEMENT OF WATER SYSTEM PRESSURES AND PEAK
DEMANDS
The TWS distribution system pressures is managed to ensure that water pressure is within
acceptable ranges for both domestic use and fire flow demands. Peak demands can be
met with combinations of increased pressure rates and water from storage tanks.
Exchange or Transfer Opportunities
TWS maintains three connections to the Metropolitan system and four emergency inter-
connections with neighboring public water systems to ensure a backup supply in the
event of a short-tean emergency situations. The Metropolitan connections are typically
operated as constant flow sources, but they function as emergency standby sources when
pressures drop significantly. The other interconnections are noanally closed, but the
valves can be opened in emergency situations.
In addition to emergency connections, water exchange or transfer opportunities outside of
MWDOC, EOCWD, and OCWD are obtainable if needed. However, based on the current
availability of groundwater and imported water, along with the opportunity for recycled
water to TWS, no water exchanges or transfers are being considered at this time.
Conjunctive Use Programs
Groundwater storage programs will help to ensure adequate water supplies in the future
and in time of drought. A conjunctive use program, where water is stored under ground
during wet periods and pumped out during dry or drought periods, is an effective means
of storage. The MWDOC 2000 Regional Urban Water Management Plan discusses a
number of conjunctive use opportunities in Orange County, including the Groundwater
Replenishment System, the East Orange County Wellfield Project, the West Orange
County Wellfield Project, the Metropolitan Conjunctive Use Storage Program, and the
Basin Cleaning Vehicle. The Metropolitan Conjunctive Use Storage Program will
provide direct benefits for TWS, and each of the other named projects will also benefit
the water reliability of TWS.
Metropolitan and OCWD have proposed a conjunctive use project to fund approximately
7 -10 wells strategically sited throughout the OCWD service area that will extract
approximately 20,000 AF of pre-stored water during call periods. The number of wells
constructed depends upon the amount of storage, well capacity, and a three-year
extraction period. The metropolitan wells are constructed, maintained and connected to
4-4

individual groundwater producer systems. Groundwater producers would be able to use
the OCWD wells to provide backup pumping capacity for their water systems, but not to
meet the OCWD Basin Pumping Percentage. The agreement is for 25 years, and the
program may be cycled additional times depending upon future drought scenarios.
During dry years, the additional wells would reduce TWS's dependence on imported
water and would provide greater reliability. The cost of the alternative water supply
would be equal to the full-service Metropolitan rate. Additional benefits of the program
include greater reliability and flexibility, and managing coastal water levels and water
quality in the region to protect the groundwater basin.
Recycled Water Projects
TWS supports current and future efforts of the regional water management agencies to
utilize recycled water as a primary resource for groundwater recharge in Orange County,
and the local agencies use of recycled water. Since TWS receives approximately 85
percent of its water supply from groundwater, it benefits from the use of recycled water.
Ocean Desalting
Ocean desalting generally has been viewed as a "last resort" water supply source.
Communities such as Santa Barbara and Catalina Island have constructed desalting plants
due to their difficulties in obtaining other supplies. However, many new plants are being
proposed along the ocean coast next to power plants to assist in lowering the cost per AF
of product water. Technological improvements have lowered and should continue to
lower this cost in the future, but power remains a major expense. Environmental issues,
permitting, and regulatory issues continue to be an area of concern even though desalted
water supply is considered loo percent reliable, drought proof and the product water is of
excellent quality because of technological developments.
OCWD conducted a study, Seawater Desalination Concept Analysis, in March 1999, to
determine the relative cost-effectiveness of ocean desalting compared to other potential
supplies. The study concluded that desalted water unit costs range from $1,150 to $1,550
per AF. This continues to remain two to three times higher than the cost of imported
water. However, more recent studies and proposals have shown the cost per AF of
product water is reducing, resulting in a great source of local cost effective water.
In August 2oo1, Metropolitan launched the Metropolitan Seawater Desalination Program.
The program objectives were to provide financial and technical support for the
development of cost-effective seawater desalination projects that will contribute to
greater water supply reliability. A call for proposals produced five projects by member
agencies including the Los Angeles Department of Water and Power, Long Beach Water
Department, Municipal Water District of Orange County, San Diego County Water
Authority, and West Basin Municipal Water District. Collectively, the projects could

use efficiency programs, water demand is projected to increase at a yearly rate of
approximately 0.43 percent. Table 5.1 shows past, current and projected water use
between 1995 and 2020. The decrease in water usage from 1995 to 2oo0 was the result of
the major impacts that policies, programs, and technology (ultra-flow toilets, high-

WATER DEMAND MANAGEMENT MEASURES
6.1
INTRODUCTION
TWS recognizes water use efficiency as an integral component of current and future
water strategy for the City. Through the California Urban Water Conservation Council's
(CUWCC) Memorandum of Understanding Regarding Urban Water Conservation in
California (MOU), 14 Best Management Practices (BMPs) have been established. These
BMPs refer to policies, programs, rules, regulation and ordinances, and the use of
devices, equipment and facilities that, over the long term; have been generally justified
and accepted by the industry as providing a "reliable" reduction in water demand. The
BMPs are technically and economically reasonable and not environmentally or socially
unacceptable, and are not otherwise unreasonable for most water suppliers to carry out.
MWDOC is signatory to the MOU and provides the following on behalf of its member
agencies:
I. An on-going water use efficiency program support for member agencies.
2. Lead agency to implement water use efficiency programs that are more cost-
effectively implemented on a regional basis rather than a local basis.
3. Secures outside funding for water use efficiency projects and programs from
Metropolitan's Conservation Credits Program, United States Bureau of Reclamation,
State Water Resources Control Board, and other sources.
6.2
DEMAND MANAGEMENT MEASURES (BMPs)
TWS has continued to work with Metropolitan, MWDOC, and EOCWD towards
implementing the 14 cost-effective BMPs, which are incorporated in regional water
agencies rate surcharges. These 14 BMPs include technologies and methodologies that
have been sufficiently documented in multiple demonstration projects that result in more
efficient water use and conservation.
BMP 1 - Residential Water Surveys for Single and Multi-Family Residential
Customers
Residential surveys in Tustin have been done on an informal basis by customer request
through a high water bill complaint or meter reading that indicated higher than normal
usage. In 1997, MWDOC began accessing Metropolitan funding assistance for residential
surveys, which included retrofitting high water-using devices with low flow devices.

BMP 2 - Residential Plumbing Retrofits
MWDOC has tracked distribution and installation of 6,973 low-flow showerheads on
behalf of TWS from FY 1995/96 and FY 1999/00.23 Estimated potential water savings
from installing low-flow showerhead is projected at 42 AFY.
BMP 3 - Distribution System Water Audits, Leaks Detection and Repair
As addressed within TWS's Water Master Plan, TWS is evaluating their distribution
system to meet all demand conditions, including peak hour demand and maximum day
demand plus fire flow.24 In addition, the distribution system will be sized to allow an
even distribution of flow to reservoirs during low demand periods. As part of the TWS
Water CIP, a program has been developed and scheduling is in place to retrofit old
distribution pipelines on an annual basis. These distribution system improvements
include water main replacement budgeted at $2.0 million per year from 2000 to 2004 and
budgeted at $1.0 million per year for eight years thereafter.
TWS maintains an emergency response program that aggressively repairs main breaks,
hydrant leaks or breaks, and meter leaks. A team of water service workers are available to
permanently repair main or hydrant breaks, and promptly restore water service. Both
proactive and "inform and response" approaches are utilized for water meter leaks. All
meter leaks are investigated and repaired the same day, unless unable to do so, then next
day service is performed.
TWS's unaccounted for water percentage is monitored on a monthly basis. For Fiscal
Year 200012001, unaccounted water usage was 10.4%.25 Distribution system leak
detection and repairs have been made to lower the unaccounted water usage to the cost-
effective standard set by the American Water Works Association (A WW A) of 9%. The
level of unaccounted water will continue to be regularly monitored. If water losses were
to rise appreciably and if cost-effective, a system wide survey of distribution facilities
would be implemented.
BMP 4 - Metering with Commodity Rates
TWS requires meters for all new water connections and bills by volume of use. All water
service connections, with the exception of dedicated fire services, are metered. TWS has
retrofitted all existing unmetered connections to be metered.

Program allows landscapers to stay abreast of the policy and activities of the water
agencies, and proper cultural practices within their industry. As part of the program, a
Landscape Certification is offered.
These programs directly benefit TWS through landscape contractor activities. Such
activities include landscape irrigation budgets, green material management, computer
controlled irrigation systems, and bilingual irrigation management training, including
advanced irrigation schedule programming and plant identification to promote use of arid
climate plantings.
BMP 6 - High-Efficiency Washing Machine Rebate Programs
Through MWDOC, a $100 rebate is in existence for the purchase of a high efficiency
clothes washer for machines installed in Orange County. These machines have a potential
to save up to 9,000 gallons of water per machine a year.27
Southern California Edison (SCE) initiated a High Efficiency Clothes Washer (HECW)
Rebate Program in 1999. The HECW Program consists of two different tiers of rebates
($50 and $100) based on the level of energy savings by specified high-efficiency clothes
washers. Metropolitan participated in the program, including Orange County, which has
contributed $35 for the water savings.

BMP 7 - Public Information Programs
MWDOC provides a comprehensive public information program built around
communication, coordination and partnerships. TWS participates in the monthly Public
Affairs Workgroup meetings conducted by MWDOC with its member agencies to
coordinate public outreach efforts and share information and ideas on a countywide basis.
TWS and MWDOC partners together on a public information education and outreach
program that provides information regarding present and future water supplies, the
demands for a reliable supply of high quality water, and the importance of implementing
water efficient techniques and behaviors. TWS informs their water customers of
upcoming public information events and encourages participation in water conservation
efforts and programs sponsored by EOCWD, MWDOC, and Metropolitan. Through a
variety of public information programs, MWDOC has assisted TWS in promoting water
conservation awareness in the annual statewide Water Awareness Month held in May and
the National Drinking Water Week; which includes a Children Drinking Water Festival
geared to promote water education, a poster and slogan contest, and distribution of water
education kits to classrooms. TWS regularly distributes a host of information materials to
the public, including newsletters, fact sheets, brochures, issue bulletins, manager's
reports, annual reports, briefing books, press kits, exhibit booths and displays.
BMP 8 - School Education Programs
Through MWDOC, water education programs are available to the TWS's public and
private schools. Specific programs with State-approved curriculum are offered for
students from kindergarten through high school. Programs include classroom
presentations by MWDOC staff teachers, audio-visual programs, hands-on activities,
take-home materials for students, and workbooks and supplies for teachers.
During the 1999/00 school year, nearly 120,000 students were educated in Orange
County through MWDOC's program and over 500,000 students since 1995.28 The
number of students educated annually has doubled since 1979/80. The number of
students reached in the City of Tustin through MWDOC's Water Education Program is

BMP 9 - Commercial, Industrial and Institutional Programs
In FY 1995/96, MWDOC designed and implemented a Commercial, Industrial and
Institutional (CII) Water Use Survey Program on behalf of its member agencies with
funding from Metropolitan and the U.S. Bureau of Reclamation (USBR). Through FY
1995/96 to 1999/00; five CII sites were surveyed for TWS on the behalf of MWDOC. A
trained auditor visited each location to survey all water using devices at each site.
Participants received a report detailing potential water saving areas, both through
behavioral modifications and the retrofitting of specific low-flow devices.
During fiscal years 1997/98 and 1998/99, MWDOC developed an in-house CII rebate
program utilizing funding provided by Metropolitan and the Orange County Sanitation
District (OCSD). MWDOC's CII rebate program signified the first time MWDOC was
able to acquire funds from the local waste water agency (OCSD) to assist in the
installation of retrofit devices aimed at reductions in waste water flows. Participants from
the CII Program were solicited to participate with rebate funds targeting specific devices
identified through the survey process. Tustin was successful in securing two service area
participants in the rebate program.
During fiscal year 1999/00, MWDOC phased out its own rebate program and began
arrangements to participate in Metropolitan's regional rebate program. MWDOC will
work with its member agencies, including Tustin, to target smaller commercial and
institutional sites to retrofit high water using devices. In order to provide the highest
possible funding incentive, MWDOC is looking to OCSD, OCWD, and highly motivated
member agencies to augment the funding provided by Metropolitan.
Since 1999, TWS has been participating in OCWD's Hotel and Motel Water
Conservation Program. This program offers free laminated hangers to promote the reuse
of towels and bed linens for multiple day usage. In addition, hotels and motels that sign
up for the program also receive a bilingual instructional video for use in training their
housekeeping staff. This program allows the guests and the hotel or motel to be
environmentally aware while reducing water use, lowering costs, savings energy, and
reducing pollution.
Through OCWD, TWS promotes a Restaurant Water Conservation Program that offers
free laminated tent cards for restaurant to place on their tables. The cards explain to
guests the restaurants' interest in helping conserve water for Orange County and that the
restaurant will only be serving water upon request.
TWS will continue to promote and support the regional CII Program through ongoing
program endorsement and distribution of informational brochures. MWDOC will provide
program effectiveness and conservation savings information, and will fund the program
through their budget.

BMP 10 - Wholesale Agency Assistance Programs
As a member agency of MWDOC, TWS receives assistance to implement water use
efficiency programs. MWDOC has provided the following assistance: 1) acquisition of
annual grant funding from a variety of sources; 2) implementation of regional programs
on behalf of Tustin and all Orange County water agencies; and 3) technical assistance
regarding local program design and implementation, benefit/cost analysis, conservation
based rate structures, and program marketing.
TWS will continue to work cooperatively with MWDOC to participate in regional BMP
programs, informational groups and projects, determination of the most cost-effective
BMPs, and tailoring programs specific to TWS.
BMP 11 - Conservation Pricing
A definition of conservation pricing is "rates designed to recover the cost of providing
service." TWS's rates are designed in this manner. Customers are billed bimonthly on
the basis of a commodity charge, a fixed customer charge.29 TWS rate structure for
FY2000/2001 is a tiered system with the following rates based on consumption; I) up to
6 ccf - $0.35/ccf (I ccf = 748 gallons); 2) up to 40 ccf - $1.l2/ccf; 3) up to 60 ccf -
$1.20/ccf; and 4) above 60 ccf - $1.32/ccf. The customer charge is based on meter size,
which for a standard residential meter is $16.00 per the bimonthly billing period.
The commodity component of the monthly water service charge is structured to recover
the actual cost of water, including the groundwater replenishment assessment (RA),
imported water charges, and energy and maintenance on TWS's water production
facilities. The fixed portion of the monthly charge is designed to cover the cost of water
distribution, meter reading and maintenance of the water distribution system, as well as a
portion of the capital improvement program. Distribution and production are distinct
programs in the annual water division budget. Applicable portions of administration,
engineering and water quality costs were assigned to each rate program when the current
water rates were designed.

TWS assigns staff to work closely with the Water Use Efficiency staff at MWDOC to
provide successful execution of regional programs, and those conducted on behalf of
TWS. TWS may either directly participate in or be represented by MWDOC in regional
workgroups including the Water Use Efficiency Workgroup, Public Affairs Workgroup,
County of Orange Supervisor's Water Task Force, and the Orange County Water Use
Efficiency Steering Committee.
BMP 13 - Water Waste Prohibition
The City Council passed Ordinance No. 1063 (April 1991) which allows passage of a
resolution from time to time to impose charges, surcharges, and penalties as deemed
necessary to accommodate water allocations, charges and penalties imposed by
Metropolitan, and other factors affecting the supply and cost of water to the City.
Ordinance No. 1063 is located within Appendix D. This Ordinance includes provisions
stating that at no time shall water be wasted or used unreasonably. The ordinance is
phased into four water conservation stages from voluntary compliance (water watch) to
mandatory compliance (water emergency). The ordinance prohibits "gutter flooding,"
where water is wasted from inefficient irrigation practices or any other water usage onto
any public street or alley. This ordinance is also incorporated into the City's Water
Shortage Contingency Plan to comply with Section 1O631(e)(6) of the Act "Penalties or
charges for excessive use. " Resolution 92-49 amends Ordinance No. 1063 by rescinding
all additional charges and penalties for excessive water use based on Metropolitan's
adjustment in voluntary water use reduction. Metropolitan had imposed severe financial
penalties on the City if it were not to achieve a 30 percent reduction in imported water
purchases; however, in 1992, Metropolitan modified its requirements to request a
voluntary 10 percent reduction in water use and rescinded its penalties for excessive use.
BMP 14 - Residential Ultra-Low-Flush Toilet (ULFT) Program
The ULFT Program is sponsored by the Water Use Efficiency Steering Committee,
which includes OCWD, MWDOC, OCSD and other cities and water districts in Orange
County. This Steering Committee participates in underwriting the no-cost, ultra-low-flush
toilet program that encourages county residents to replace inefficient toilets. The program
could eventually replace 900,000 residential toilets in Orange County, creating an annual
savings of approximately 25,000 AF of water per year.
TWS customers have participated in various regional programs that are jointly funded
from the foregoing entities through ULFT Give-Aways and ULFf Rebate Programs.
From 1995 through 2000, approximately 3,770 toilets that were 3.5 gallons per flush or
more were replaced with ULFfs (Table 6.2). Total water savings from these toilets are
estimated at 138 AFY.3°

CAPITAL IMPROVEMENT PROJECTS (CIP)
TWS has developed a Water Capital Improvement Program (CIP) to minimize the
dependence on imported water supply and to foster a program to increase the
groundwater quality in the aquifer underlying the service area. TWS's goal is to develop
local groundwater sources that when combined with treated groundwater supplies will
provide 100 percent of the required supply within the next 20 years. Together with
Metropolitan's Local Resource Program (Groundwater Recovery), TWS is implementing
a groundwater development program to utilize existing wells and drill additional wells to
make use of the local groundwater supply. TWS has seven existing untreated-
groundwater wells.
As part of the CIP, the following reservoirs will have major to minor retrofits: I) the
existing Main Street and Rawlings Reservoirs will be replaced at the same sites to
increase the system storage capacity to 13.83 MG; 2) the Foothill and Simon Ranch
Reservoirs will have structural rehabilitation, including replacement of the Simon Ranch
Booster Pump Station in FY 2005/06; and 3) the John Lyttle and Newport Avenue
Reservoirs will have minor rehabilitation.
Regarding the distribution system, the CIP addresses resizing of the pipeline system to
distribute water throughout the system to meet all demand conditions including peak hour
demand and maximum day demand plus fire flow.
6.4 LANDSCAPING AND IRRIGATION PRACTICES
TWS is promoting water conserving related landscape activities to its customers by
demonstrating the practicality and the appeal of the latest technology and research into
their landscaping and irrigation practices. TWS is evaluating several models of
Evapotranspiration-based irrigation controllers, which will reduce water usage by 25% to
35%.
Since 1995, Tustin's median designs have utilized an inward sloping perimeter to retain
water. Irrigation systems are monitored and adjusted constantly to prevent overspray and
over-watering. If a system is wasting water, the system is immediately repaired,

modified, or replaced. Drought resistant landscaping is used wherever possible to reduce
water consumption.
6.5
ALTERNATIVE WATER CONSERVATION PROGRAMS
In addition to meeting the Metropolitan and MWDOC BMP's requirements, TWS has
implemented additional water conservation related activities, including outreach
programs. TWS is continuing to work towards the development and implementation of
outreach programs designed to identify high water consumption. TWS is dedicated to
being responsive to broken sprinklers and water misuse when notified by its customers.
Upon identification of high water consumption or misuse, TWS will efficiently
investigate the report and inform the customer of any problems found, as well as possible
water conservation measures. An informational packet containing water conservation tips
and landscaping ideas, as well as a water conservation kit is available to customers upon
request or within the Public Works Department.
6.6
WATER USE EFFICIENCY PROGRAM SCHEDULING AND
EFFECTIVENESS
The Orange County Water Plan, Focus on Orange County's Water Future, as discussed
in the MWDOC's Regional UWMP, adapts and applies the Metropolitan-Main Model.
The Model forecasts water demands on both a regional basis and at the retail level to
produce an estimate of future water demand, the identification of potential benefits, and
costs associated with implementation of the BMPs. The conservation potential by retail
water agency is used to develop BMP implementation plans using a "least cost approach"
to develop a "most cost effective" package of BMP programs customized for each retail
agency. A Conservation Savings Model estimates the potential water conservation from
implementation of the BMPs. Once the potential water savings are quantified, programs
can be developed to target potential savings. From this model, implementation plans will
be developed by MWDOC for each retail agency, detailing the most cost-effective BMPs,
including wholesale-level wastewater.
Quantifiable BMP programs include ULF toilet and low-flow showerhead retrofits, water
audits and conservation pricing. Programs and activities that are not quantifiable, but
known to save water, include public information, school education, conservation
coordinator, water waste prohibitions, and metering with commodity rates.
Water use efficiency is an integral part of water supply planning and operations. TWS
works to improve the understanding of costs and benefits of conservation so that
investment decisions are efficient and effective at meeting program goals. As a
cooperative member of California's conservation community, TWS supports MWDOC's
significant contributions to the development and coordination of water use efficiency
activities for its member agencies and throughout Orange County.

WATER SHORTAGE CONTINGENCY PLAN
7.1
INTRODUCTION
One dry year does not constitute a drought in California, but does serve as a reminder of
the need to plan for droughts. California's extensive system of water supply
infrastructure, its reservoirs, groundwater basins, and inter-regional conveyance facilities,
mitigates the effect of short-term dry periods. Defining when a drought begins is a
function of drought impacts to water users. Drought is a gradual phenomenon. Although
droughts are sometimes characterized as emergencies, they differ from typical emergency
events. Droughts occur slowly, over a multiyear period. Drought impacts increase with
the length of a drought, as carry-over supplies in reservoirs are depleted and water levels
in groundwater basins decline.
In order to meet short-term water demand deficiencies, and short- or long-term drought
requirements, TWS has implemented its own water shortage policy, Water Shortage
Contingency Plan, in accordance with MWDOC and OCWD water shortage/drought
activities. TWS will respond to MWDOC's water shortage and drought management
policy, which is based on Metropolitan's adopted Water Surplus and Drought
Management Plan (WSDM Plan). The WSDM Plan guides the management of regional
water supplies to achieve the reliability goals of Southern California's Integrated Water
Resource Plan.
7.2
THREE YEAR MINIMUM WATER SUPPLY
According to MWDOC, Metropolitan projects 100 percent reliability for full-service
demands through the year 2010 through their modeling under the WSDM Plan.
Additionally, through a variety of groundwater reliability programs conducted by OCWD
and participated in by TWS, local supplies are projected to be maintained at demand
levels. TWS anticipates the ability to meet water demand through the next three years
based on the driest historic three-years as shown in Table 7.1.

SUPPLEMENTAL WATER SUPPLIES
Over the past several years, TWS has taken steps to insure an adequate and reliable water
supply for the community. Well and storage studies have been made by independent
consulting engineering finns to detennine sufficient water supply and emergency
supplies. Future studies will be made of the TWS transmission and distribution system to
increase its reliability and provide a better quality of water to meet the needs of it's of
customers.
Approximately 85 percent of the TWS water is supplied from groundwater wells from the
Santa Ana River groundwater basin. From 1995 to 2000, TWS treatment facilities
provided an average of 29 percent of the total amount of groundwater pumped. Basin
groundwater produced through treatment plants is exempted from the BEA. The
remaining 15 percent of TWS's supply is from Metropolitan imported water through
MWDOC and EOCWD.
MWDOC and OCWD have implemented water supply alternative strategies for the
region and on behalf of its member agencies to insure available water in the future and
during shortages. Supplemental water supplies are discussed in more detail in Section 4,
Water Reliability Planning. Supplies discussed include management of water system
pressures and peak demands, water exchanges or transfers, conjunctive use programs,
recycled water projects, and desalination. These options include programs for expanded
local supplies. Additional actions to manage limited supplies would include both
operational and demand management measures, encompassing alternative rate structures,
distribution of water use efficiency devices, and enhanced school education and public
infonnation.
The MWDOC 2000 Regional UWMP further discusses programs by MWDOC, OCWD
and Metropolitan for the benefit of the region and its member agencies, including Tustin.
7.4
WATER SHORTAGE CONTINGENCY PLAN
The Tustin City Council adopted the Water Shortage Contingency Plan on February 3,
1992, by Resolution No. 92-15, which are both shown in Appendix E. This four-stage
program, known as the Water Management Program, establishes water conservation
measures ranging from a voluntary 10 percent reduction at Stage 1, through a mandatory
5 percent reduction at Stage 4. Resolution No. 92-15 provides TWS the ability to obtain
a higher level of water efficiency and allows the City Manager, through Council
ratification, the flexibility to adjust to any rapidly varying water supply situation.
As previously discussed in Section 6, Ordinance No. 1063, adopted in April 1991,
established a mandatory water conservation and rationing program to reduce
consumption by 15 percent.

Section 7
Historic Council actions demonstrate a firm commitment to managing water in times of
shortage and the value of planning for the future. The following additional water
management related resolutions and ordinances that the City Council has enacted are
located in Appendix F:
.
Resolution No. 96-18 (2/20/96) - Adoption of the 1995 Urban Water
Management Plan
.
Ordinance No. 1060 (3/18/91) - Adoption of the City's Water Management Plan
that maintains an adequate water supply for health and welfare of customers
depending on seasonal demand considerations as well as mandatory provision to
reduce gutter flooding. A copy of this ordinance is included in the City's Water
Shortage Contingency Plan.
.
Resolution No. 90-53 (5/21/90) - Adoption of a voluntary water conservation
program to reduce water consumption by 10 percent.
The City Manager is authorized and directed by City Council to implement provisions of
the Water Management Program. All actions taken will be confirmed at the earliest
practicable time by the City Council. The City would also consider and incorporate the
policies of MWDOC and OCWD water shortage/drought activities, including
Metropolitan's WSDM Plan. Details of the WSDM Plan can be reviewed in the
Metropolitan 2000 Regional Urban Water Management Plan.
Rationing Stages and Reduction Goals
In order to meet short-term water demand deficiencies and short- or long-term drought
requirements, TWS will implement its own water shortage policy in accordance with the
City's Water Conservation Program and the policy of MWDOC, which will likely be
based on Metropolitan's WSDM Plan.
The WSDM Plan guiding principle is to minimize adverse impacts of water shortage and
ensure regional reliability. From this guiding principle come the following supporting
principles:
. Encourage efficient water use and economical local resource programs.
. Coordinate operations with member agencies to make as much surplus water as
possible available for use in dry years.
. Pursue innovative transfers and banking programs to secure more imported water
for use in dry years.
. Increase public awareness about water supply issues.
The WSDM Plan defines the expected sequence of resource management actions that
Metropolitan will take during surpluses and shortages of water to minimize the
probability of severe shortages that require curtailment of full-service demands. The
7-3
Final November 2004
City of Tustin
2000 Urban Water Management Plan Update
Section 7
MWDOC 2000 Regional UWMP details each of the surplus and shortage stages, actions
by stage and allocation of supply. Mandatory allocations are avoided to the extent
practicable; however, in the event of an extreme shortage: an allocation plan will be
adopted in accordance with the principles of the WSDM Plan.
Under a drought scenario, Metropolitan replenishment water may be temporarily
unavailable to OCWD for replenishment of the groundwater basin. OCWD would first
attempt to purchase other water supplies at a similar cost to replace the Metropolitan
source. If no alternative water supply sources are economically available, OCWD may
temporarily adjust the Basin Production Percentage (BPP) to meet local demand and refill
the basin in the future. OCWD used this strategy during the later years of the 1986-92
drought period.
If this option is not available, then OCWD may lower the BPP to match the basin's
Dependable Yield. Under this last scenario, TWS may request increased import water
along with conservation and water use efficiency measures by water use category to meet
demand. The OCWD Master Plan Report, Chapter 14 - Basin Management Issues,
further describes OCWD activities that may affect TWS during a declared drought.
Health and Safety Requirements
The primary goal of TWS is to preserve the health and safety of its personnel and the
public. Meeting this goal is a continuous function of the system - before, during and after
a disaster or water shortage. Fire suppression capabilities will continue to be maintained
during any water shortage contingency stage. Some water needs are more immediate than
others. The following list of public health needs and the allowable time without potable
water is a guideline and will depend on the magnitude of the water shortage:
. Hospitals - continuous need
. Emergency shelters - immediate need
. Kidney dialysis - 24 hours
. Drinking water - 72 hours
. Personal hygiene, waste disposal - 72 hours
Based on commonly accepted estimates of interior residential water use in the United
States, Table 7.2 indicates per capita health and safety water requirements. During the
initial stage of a shortage, customers may adjust either interior and/or outdoor water use
in order to meet the voluntary water reduction goal.

for enforcement, service of water would be discontinued or appropriately limited to any
customer who willfully uses water in violation of any provision of the ordinance.
TWS will follow the allocation plan guidelines of MWDOC as adopted by Metropolitan
once an extreme shortage is declared. This allocation plan will be enforced by
Metropolitan using rate surcharges. MWDOC will follow the guidelines of the allocation
plan and impose the surcharge that Metropolitan applies to its member agencies that
exceed their water allocation. TWS would correspondingly impose surcharges or
penalties in accordance with its ordinance on excessive use of water.

REVENUE AND EXPENDITURE IMPACTS AND MEASURES TO
OVERCOME THOSE IMPACTS
TWS receives water revenue from a commodity charge and a fixed customer minimum
charge. The rates have been designed to recover the full cost of water service in the
commodity charge. Therefore, the total cost of purchasing water and producing
groundwater would decrease as the usage or sale of water decreases. Should an extreme
shortage be declared and a large reduction in water sales occur for an extended period of
time, TWS would monitor projected revenues and expenditures, and then reexamine its
water rate structure.
7.7
MECHANISM TO DETERMINE REDUCTIONS IN WATER USE
Under normal conditions, potable water production figures are recorded daily. Weekly
and monthly reports are prepared and monitored. This data will be used to measure the
effectiveness of any water shortage contingency stage that may be implemented.
As stages of water shortage are declared by MWDOC, TWS will follow implementation
of those stages and continue to monitor water demand levels. It is not until Shortage
Stage 5 that Metropolitan may call for extraordinary conservation. During this stage,
Metropolitan's Drought Program Officer will coordinate public information activities
with MWDOC and monitor the effectiveness of ongoing conservation programs.
Monthly reporting on estimated conservation water savings will be provided.
TWS will participate in monthly member agency manager meetings with both MWDOC
and OCWD to monitor and discuss monthly water allocation charts. This will enable
TWS to be aware of import and groundwater use on a timely basis as a result of specific
actions taken responding to the Water Shortage Contingency Plan.
7.8
PREPARATION FOR CATASTROPHIC WATER SUPPLY
INTERRUPTION
Water Shortage Emergency Response
A water shortage emergency could be catastrophic event such as result of drought,
failures of transmission facilities, a regional power outage, earthquake, flooding, supply
contamination from chemical spills, or other adverse conditions. TWS maintains and
exercises a comprehensive Emergency Management Program for such emergencies
including Water Shortage Emergency Response.
The Water Shortage Emergency Response Plan includes the organizational and
operational policies and procedures required to meet the needs of sufficient water for
firefighting operations and safe drinking water, and provides a system for organizing and

prioritizing water repairs. It also cites authorities and specifies the public and private
organizations responsible for providing water service.
TWS will operate under nonnal operating procedures until a situation is beyond its
control. This includes implementation of any allocation plan passed through by MWDOC
for Metropolitan and water shortage contingency plans of OCWD.
If the situation is beyond TWS's control, the City's Emergency Operations Center (EOC)
may be activated to better manage the situation. If the situation warrants, the EOC may
be activated at which time a water representative will be sent to the EOC to coordinate
water emergency response.
In the event the EOC is activated, the City Management Policy Group will set priorities.
When the EOC is activated, the TWS will take its direction from the EOC. An EOC
Action Plan will be developed in the EOC that will carry out the policies dictated by the
Policy Group. The TWS will use the EOC Action Plan in detennining its course of
action.
If the situation is beyond TWS and the City's control, additional assistance will be sought
through coordination with the Water Emergency Response Organization of Orange
County and the County Operational Area.
Water Emergency Response Organization of Orange County (WEROC)
In 1983, the Orange County water community developed a Water Supply Emergency
Preparedness Plan to respond effectively to disasters impacting the regional water
distribution system. This plan was jointly funded by three regional water agencies:
Coastal Municipal Water District, MWDOC, and OCWD, with the support and guidance
from the Orange County Water Association (OCW A). The collective efforts of these
agencies resulted in the fonnation of the countywide Water Emergency Response
Organization of Orange County (WEROC), which is unique in its ability to provide a
single point of contact for water representation in Orange County during a disaster.
WEROC perfonns coordination of infonnation and mutual-aid requests among Orange
County water agencies, and conducts disaster training exercises for the Orange County
water community and with Metropolitan. The MWDOC 2000 Regional Urban Water
Management Plan, Section 7, presents the details of WEROC.
TWS actively participates in the WEROC training exercises and provides WEROC with
listing of equipment, vehicles, and materials that can be made available to other agencies
during an emergency.
Additional emergency services available to TWS through the State of California include
the Master Mutual Aid Agreement, WARN and Plan Bulldozer. The Master Mutual Aid
Agreement includes all public agencies that have signed the agreement and is planned
through the California Office of Emergency Services. The California Water Agencies

WATER RECYCLING
8.1
RECYCLED WATER
The Southern California region, from Ventura to San Diego, discharges over I billion
gallons (1.1 million AFY) of treated wastewater to the ocean each day. This is considered
a reliable and drought-proof water source and could be utilized to greatly reduce southern
California's reliance on imported water. As technological improvements continue to
reduce treatment cost, and as public perception and acceptance continue to improve,
numerous reuse opportunities should develop.
TWS currently does not utilize or serve recycled water to any of its customers or for
municipal uses. However, TWS supports efforts of the regional water management
agencies to utilize recycled water as a primary resource for groundwater recharge in
Orange County. Since TWS receives approximately 85 percent of its water supply from
groundwater, it indirectly uses and benefits from recycled water.
8.2
WASTEWATER COLLECTION AND TREATMENT IN TUSTIN
The Orange County Sanitation District (OCSD) is a "special district," single purpose
entity formed solely for the processing and disposal or reuse of wastewater and its
residuals. The District serves a population of approximately 2.3 million people living in a
476 square mile area that encompasses the majority of metropolitan Orange County,
including 23 of the County's 34 cities. During 2002, an average daily sewage influent
rate of 236 MGD was treated and was estimated in an amount of 542 wet tons per day of
biosolids were produced.31
OCSD operates the third largest wastewater system on the west coast, consisting of over
500 miles of trunk sewers and 200 miles of subtrunk sewers, two regional treatment
plants, and an ocean disposal system.
Sewer Systems
The Tustin sewer system includes approximately 51.5 miles of mostly 8-inch vitrified
clay pipe (VCP) sewer lines and 1,033 manholes. Sewer infrastructure in the City is
currently owned and operated by OCSD, as well as by Irvine Ranch Water District in the
newer sections of the City, including Peters Canyon.
In February 2004, OCSD began widespread public outreach campaign to inform the
Tustin population that OCSD would be performing sanitary sewer construction work
beginning in March 2004 and scheduled for completion by November 2005. The project
consists of replacing sewer pipes, water mains and abandoning deteriorated pips and

replacing them with new pipes to withstand the increased flow generated by the increased
population.
Tustin's wastewater flows are directed to OCSD for treatment. The OCSD sewerage
system collects wastewater through an extensive system of gravity flow sewers, pump
stations, and pressurized sewers (force mains). The sewer system consists of 12 trunk
sewer systems ranging in size from 12 to 96 inches in diameter and collectively, with
local collection lines, OCSD owns and operates 650 miles of lines. Additionally, there
are 39 sewer interconnections and 87 diversions to maximize conveyance of flows
through the system. Twenty pump stations are used to pump sewage from lower lying
areas to the treatment plants.
OCSD Treatment Plants
Tustin directs is wastewater flow to OCSD's Reclamation Plant No.1, which is located in
Fountain Valley about 4 miles northeast of the ocean and adjacent to the Santa Ana
River. The plant provides advanced primary and secondary treatment and supplies
secondary treatment water to OCWD, which further treats and distributes the water for
various uses, including irrigation, groundwater recharge, and operation of the coastal
seawater barrier system. If needed, Tustin could direct its wastewater flows to OCSD's
Treatment Plant No.2.
The treatment process at Reclamation Plant No.1 includes secondary treatment through
an activated sludge system. This plant receives raw wastewater from six major sewer
pipes, often called "interceptors" or "trunk lines." This plant also receives backwash
brine from the OCWD's Water Factory 21 treatment plant. The secondary effluent is
either blended with the advanced primary effluent and routed to the ocean disposal
system, or is sent to the OCWD facility for advanced treatment and recycling. The solid
materials removed in the treatment systems are processed in large tanks to facilitate
natural decomposition. Half of the material is converted to methane, which is burned as
fuel in the energy recovery system, and the remaining solids are used as a soil
amendment or fertilizer in Kern, Kings, Riverside, and San Diego Counties.
OCSD's Treatment Plant No.2 is located adjacent to the Santa Ana River and about
1,500 feet from the ocean. This plant provides a mix of advanced primary and secondary
treatment. The plant receives raw wastewater through five major sewers. The treatment
process is similar to Plant No.1. Approximately 33 percent of the influent receives
secondary treatment through an activated sludge system, and all of the effluent is
discharged to the ocean disposal system.
Tustin wastewater flows are directed to OCSD Reclamation Plant No.1. Current average
daily flow of wastewater received at Plant No.1 is 88 million gallons per day (mgd) of
wastewater, with a primary treatment capacity of 108 mgd.

8.3
REGIONAL RECYCLED WATER PLANNING
TWS supports efforts of the regional water management agencies to utilize recycled
water as a primary resource for groundwater recharge in Orange County. Since TWS
receives 85 percent of its water supply from groundwater, it benefits from the use of
recycled water for groundwater recharge.
Recycled water in Orange County is also used to irrigate crops, golf courses, parks,
schools, business landscapes, residential lawns, and some industrial uses. In 1999/00,
over 30,000 acre-feet of recycled water was applied by water retailers in the County. In
addition, recycled water has played a significant part in the Orange County groundwater
basin by being utilized as a barrier to saltwater intrusion.
OCSD produces recycled water year round for OCWD's Green Acres Project (GAP),
providing recycled water for industrial customers and landscape irrigation in Fountain
Valley, Santa Ana, Costa Mesa, Newport Beach and Huntington Beach. It also produces
recycled water for OCWD's Groundwater Injection System. The OCWD/OCSD
proposed Groundwater Replenishment System (GWRS) would increase the use of
recycled water for groundwater recharge over the next 20 years by 119 percent.
Recycled water use and projections in Orange County can be found in the MWDOC's
2000 Regional Urban Water Management Plan. The projections for expanded
development of water recycling are based upon several "institutional assumptions" that
vary depending on the end use of the recycled water. Development of recycled water
projects generally requires creative solutions to funding, regulatory requirements,
institutional arrangements and public acceptance.
Determining the technical and economic feasibility of a recycled water project requires a
relative comparison to alternative water supply options. This comparison entails a
detailed analysis of the costs and benefits of each alternative supply. A detailed
discussion of the methods and issues in determining the relative cost effectiveness of
recycled water projects is described in the draft "Urban Water Recycling Feasibility
Assessment Guidebook," Section 3 (California Urban Water Agencies, September 1998).
In 1993, the Department of Water Resources, in cooperation with the U.S. Bureau of
Reclamation (USBR) and seven southern California water agencies, including
Metropolitan, undertook a study to evaluate the feasibility of a regional water reclamation
plan. The Southern California Comprehensive Water Reclamation and Reuse Study
(SCCWRRS) was a six-year effort to identify regional reclamation systems, and promote
efficient use of total water resources by increasing the use of recycled water and
identifying opportunities for and constraints to maximizing water reuse in Southern
California.
Based upon the 2002 Executive Summary of the SCCWRRS Final Report, a regional
water recycling system that spans the entire study area is not practical or feasible;
8-3
Final November 2004
City of Tustin
2000 Urban Water Management Plan Update
Section 8
however, subregional systems warrant further evaluation. Orange County and the Lower
Santa Ana River Watershed has been identified as one of the four geographical regions,
and is being examined for a regional water recycling system for short-term (2010) and
long-term (2040) applications. Additional information on this study has been referenced
in MWDOC's and Metropolitan's 2000 Regional Urban Water Management Plans. The
DWR, Division of Planning and Local Assistance, web site also presents information on
the SCCWRRS.
OCWD is planning large increases in indirect recycling. The amount of treated
wastewater in the Santa Ana River is projected to increase due to population growth in
Riverside and San Bernardino Counties. OCWD and OCSD's proposed GWRS program
is a single recharge project that could ultimately supply 120,000 AFY that is currently
lost to the ocean.
OCWD/OCSD Groundwater Replenishment System (GWRS)
The Groundwater Replenishment System (GWRS) is a jointly funded project of OCWD
and OCSD. The GWRS is a water supply project designed to ultimately reuse
approximately 140,000 AFY of advanced treated wastewater. The first phase is currently
underway, which will supply approximately 72,000 AFY and provide the backbone
facilities for future expansion. Phase 1 of the GWRS will have a product water capacity
of 70 mgd. Timing of future phases will be determined by projected flow requirements
for anticipated water demands.
The objective of the project is to develop a new source of reliable, high quality, low
salinity water that will be used to replenish the groundwater basin and expand the
existing seawater intrusion barrier. The GWRS would supplement existing water
supplies, and provide a new, cost-effective and reliable source of water to recharge the
Orange County Groundwater Basin, protect the Basin from further degradation due to
seawater intrusion, and augment the supply of recycled water for irrigation and industrial
use. Thus, the GWRS will be comprised of three major components: (I) Advanced Water
Purification Facilities (A WPF) and pumping stations; (2) a major pipeline connecting the
treatment facilities to existing recharge basins; and (3) expansion of an existing seawater
intrusion barrier.
The GWRS would take secondary, treated municipal wastewater from the OCSD
Treatment Plant No.2 in Fountain Valley and further clean this water to levels that
exceed current drinking water standards. This will allow it to be used for groundwater
recharge, injection into the seawater barrier, and for landscape irrigation and industrial
process water, rather than having to discharge it into the Pacific Ocean.
A portion of the treated product water would be pumped upstream via a major
conveyance pipeline generally paralleling the Santa Ana River to the OCWD spreading
basins where it would be allowed to percolate into the Orange County Groundwater
Basin. However, most of the treated water would also be injected into the ground to
create an expanded seawater intrusion barrier.

Section 8
A small portion of the treated water will be made available to supplement the irrigation
demands of OCWD's existing Green Acres Project. Some of the treated water may also
be made available for use as industrial process water, irrigation water or for other
approved uses via connections to the major conveyance pipeline in industrial areas,
business parks, golf courses, and parks located near the Santa Ana River alignment.
Some of the benefits of the proposed GWRS to TWS, MWDOC's service area, and all of
Orange County and California include:
.
Supply a significant amount of highly treated recycled water required by OCWD to
maintain a high basin production percentage through and beyond the year 2020.
Provide a reliable replenishment water supply in times of drought.
Expand the seawater intrusion barrier to sustain additional groundwater production in
the coastal zone.
.
.
Detailed discussion on the proposed GWRS can be found in the MWDOC 2000 Regional
UWMP and the OCWD Master Plan Report.
8.4
ENCOURAGING RECYCLED WATER USE
Recent studies of water recycling opportunities within southern California provide a
context for promoting the development of water recycling plans. It is recognized that
broad public acceptance of recycled water requires public education and involvement.
Public Education
TWS participates in MWDOC's public education and school education programs, which
include extensive sections on water recycling. MWDOC's water use efficiency public
information programs are a partnership with Tustin and other agencies.
Through a variety of public information programs, MWDOC assists TWS in reaching the
public with accurate information regarding present and future water supplies, the
demands for a suitable quantity and quality of water, including recycled water, and the
importance of implementing water efficient techniques and behaviors. Through
MWDOC, water education programs have reached thousands of Tustin students with
grade-specific programs that include information on recycled water.
Current programs include the Drinking Water Festival held annually during the month of
May sponsored by OCWD and the Blue Planet Foundation.

Financial Incentives
The implementation of recycled water projects involves a substantial upfront capital
investment for planning studies, environmental impact reports, engineering design and
construction before there is any recycled water to market. For some water agencies, these
capital costs exceed the short-term expense of purchasing additional imported water
supplies from Metropolitan even though a regional analysis in the SCCCWRRS shows
that net benefits are far greater than direct costs.
Funding sources are available through federal, state and regional programs to provide
significant financial incentives for local agencies to develop and make use of recycled
water. These funding sources include the United States Bureau of Reclamation (USBR),
California water bonds, and Metropolitan's Local Resources Program. These funding
opportunities may be sought by TWS or possibly more appropriately by other regional
agencies. TWS will continue to support seeking funding for regional water recycling
projects and programs. More detail on these funding programs can be found in the
MWDOC 2000 Regional UWMP.
8.5
OPTIMIZING RECYCLED WATER USE
In Orange County, the majority of recycled water is used for irrigating golf courses,
parks, schools, business and communal landscaping. However, future recycled water use
can increase by requiring dual piping in new developments, retrofitting existing
landscaped areas and constructing recycled water pumping stations and transmission
mains to reach areas far from the treatment plants. Gains in implementing some of these
projects have been made throughout the county, while efforts continue to manage the
large energy requirements, facilities, and additional costs to make the water recycling
projects economically feasibly.
To optimize the use of recycled water, costlbenefit analysis must be conducted for each
potential project. Once again, this brings about the discussion on technical and economic
feasibility of a recycled water project requiring a relative comparison to alternative water
supply options. For TWS, analysis has shown capital costs exceed the short-term expense
of purchasing additional imported water supplies from Metropolitan through EOCWD
and MWDOC.
TWS will continue to conduct costlbenefit analysis for recycled water projects, and seek
creative solutions and a balance to recycled water use, in coordination with EOCWD,
MWDOC, OCWD, Metropolitan and other cooperative agencies. These include solutions
for funding, regulatory requirements, institutional arrangements and public acceptance.

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF TUSTIN,
CALIFORNIA, ESTABLISHING.A MANDAT.ORY. WATER CONSERVATION..
AND RATIONING PROGRAM .

The City Council of the city of Tustin does hereby ordain as
follows:

SECTION 1.
Water Consumption Reduction.
7
A. Findinqs. The city Council hereby finds and determines
as follows: the state of California is entering the fifth year of
an unprecedented drought; water levels at many reservqirs are at an
all time low; deliveries of water to the Southern California region
from the state Water Project, Colorado River, Owens Valley and Mono
County have declined due to the lack of rainfall and litigation
regarding entitlement; the Metropolitan Water District of southern
California (MWD) is the supplier of thirty percent (30%) of the
water suppl'ied to the Tustin Water Service and MWD has reduced the
City's allocation of water by thirty.percent (30%) as of March 1,
199~ and advised that it will charge the city a premium of at least
'Three Hundred Ninety-Four Dollars ($394) per acre foot for delivery
of water in excess of new allocation. levels; the Mandatory
Conservation Rate on the effective date of this ordi.nance is a
collective fifteen percent (15%) ; this Conservation Rate
corresponds with the recent decision of MWDto allocate only
seventy percent (70%) of the water used. by the. City during
. comparable periods in the past; the failure 'of Tustin Water Service
consumers to collectively reduce water consumption may lead to even
more drastic cutbacks in allocations, deliveries, and costs; the
failure to reduce 'water consumption and a continuation of the
drought may, in the long term, result in the inability of. the city
to supply water at or above minimum levels required for health and
sanitation; this ordinance will promote reductions in water
consumption and permit recovery of additional costs incurred with
the purchase of water and the administration of water conservation
measures.

of the Allowable Water Usage.
19
20
2. No relief shall be granted to any customer in the

practical reduction in water consumption aside from those factors
which would otherwise warrant an adjustment. No relief shall be
granted to any customer who fails to provide the city Manager or

the adequacy of the grounds of reli~f or a finding that maximum
practical reduction and consumption has been achieved."
21
22
23
24
25
3. The decision of the city Manager or designee shall
be made after all material has been reviewed.
26

SECTION 2. The city council finds and declares that adoption
this ordinance as an emergency measure is necessary to preserve
public peace, health, and safety in that: .
California is currently experiencing a drought of
magnitude with current water reserves throughout the
far below normal.
The city has initiated a voluntary water conservation
but the program has not achieved the desired results.
c. Metropolitan Water District, the supplier of imported
to the City of Tustin, has announced its intention to reduce
amount of water delivered to the City and to impose a surcharge
sold to the City in excess of new allocation levels.
and reduced allocation 'levels were effectiv.e on
1, 1991 and compliance with MWD directives cannot be
other than through the adoption of an emergency ordinance.

E. Failure to achieve a fifteen percent (15%) reduction in
water consumption will reduce available water supplies, lead to
.further MWD mandated reductions,. and require imposition. of more

could lead to the inability of the city to provide water in amounts
necessary for health and sanitation. .

CITY OF TUSTIN
WATER SHORTAGE CONTINGENCY PLAN
INTRODUCTION
This report is a required amendment 'to the Urban Water Management Plan
(UWMP) which was prepared by the City of Tustin Water Service (TWS), and was
adopted by the City Council of the City of Tustin on March 4, 1991 by Resolution
No. 91-27 (a copy is included in the Appendix). It was submitted to the State of
California Department of Water Resources (DWR) on March 6, 1991 in response
to AB- 797.
This document has been prepared in accordance with California State
Legislature Assembly Bill 11 (AB-11) which amends Sections 10620, 10621,
10631, and 10652 of the Water Code, and adds Section 10656 (a copy of AB-11
is included in the Appendix.!. California Water Code Sections 10610 through
10656, known as the Urban Water Management Planning Act (Act), became
effective on January 1, 1984. The Act (known as AB- 797) requires every urban
water supplier providing water for municipal purposes to more than 3,000
customers or supplying more that 3,000 acre-feet of water annually to prepare and
adopt an UWMP in accordance with prescribed requirements,
AB-11 amends AB- 797 (or UWMP) to require every urban water supplier,
whether serving water directly or indirectly to customers, to prepare, adopt, and
submit to DWR a Water Shortage Contingency Plan (Plan). The nine specific
elements required by AB-11 are:
1.
2.
3.
4.
Past, current, and projected water use, and to the extent possible, a
breakdown of water use (residential, commercial, single-family, etc.)
An estimate of minimum supplies available at the end of 12, 24, and
36 months; assuming a worst case scenario (assume the years 1992,
1993, and 1994)
Stages of action that a supplier would undertake to deal with up to
a 50 percent shortage
Mandatory provisions to reduce water use
5.
Consumption limits in the rnost restrictive stages
6.
Penalties for excessive use
7.
An analysis of the effects that these measures would have on
revenues and the measures that an agency would take to overcome
revenue shortages
8.
A draft ordinance or resolution to carry out the drought plan
9.
A mechanism for determining actual reductions in water use
This Plan will cover only those items required in AB-11 and will not review
in depth any information which can be found in the City's UWMP. Reference is
also made to urban water shortage contingency plans prepared by the Municipal
Water District of Orange County (MWDOC) and the Metropolitan Water District of
Southern California (MWD). Copies of all City ordinances referred to herein can
be found in the Appendix.
2
THE PLAN
This document begins with Section 10620(d)(2) and then follows with
Section 10621 (e). which essentially is the Plan.
Sections 10631(a-d) of the Act were addressed in the City's UWMP and
therefore been omitted from this Plan.
Section 106201d)(2) of the Act requires: "Each urban water supplier shall
coordinate the preparation of its urban water shortage contingency plan with other
urban water suppliers and public agencies in the area, to the extent practicable."
TWS has coordinated its Plan through information obtained from both the
MWD and the MWDOC Water Shortage Contingency Plans, and from information
contained in the Orange County Water District (OCWD) Groundwater Manaaement
Plan.
Section 106311e) of the Water Code is amended to read:
Ie)
Provide an urban water shortage contingency plan which includes all
of the following elements which are within the authority of the urban
water supplier:
11)
Past, current, and projected water use and, to the extent records are
available, a breakdown of those uses on the basis of residential single
family, residential multifamily, industrial, commercial, governmental,
and agricultural use.
This section has been covered in Chapter 2 of the City's UWMP and in
Chapter II of the MWD and in the MWDOC plans.
3
Section 10631(e)(2) of the Act requires: "An estimate of the minimum
water supply available at the end of 12, 24, and 36 months, assuming the worst
case water supply shortages."
TWS receives approximately 30 percent of its water supply from MWD
through East Orange County Water District (EOCWD) import connections.
Assuming a worst case supply shortage scenario, this amount of water would not
be available.
TWS has interconnections with other local water agencies (see Chapter 7
of the UWMP). These interconnections are intended for use in short-term local
emergencies, such as pipeline breaks or well failures.
It is not likely that a
significant amount of water could be obtained from them in times of severe
drought.
In order to maintain an adequate water supply for the health and welfare of
its customers, TWS would request the City Council to invoke the City's Water
Management Program, Ordinance No.1 060, adopted by the City Council of the
City of Tustin on March 18, 1991. Depending on seasonal demand considerations,
one of the four stages of the ordinance would be implemented.
It has been
estimated that Stages 1 through 4 could reduce the TWS water demand between
10 and 50 percent.
TWS is currently working towards independence from import water. With
the addition of a proposed groundwater desalter which will recover the supply from
3 inactive wells, and two proposed new wells, TWS will be able to supply nearly
4
100% of its demands from the local groundwater supply. This approach is
supported by the OCWD, which manages the local groundwater basin. The
following charts illustrate current and future TWS water production along with
average and maximum day water demand projections.
".."".~"

7.7 MG TOTAL
MG = million gallons
The following average day demand projections were obtained from the
Water System Storage Evaluation Study prepared for TWS by Daniel Boyle
Engineering, Inc. on October 19, 1990. The maximum day demand projections
were derived using duty factors obtained frorn the Tustin Water Service
Management Program - Phase II, prepared for TWS by Boyle Engineering
Corporation in March, 1984. There has not been significant growth in the service
area since preparation of the program, and the values are considered accurate.
YEAR DEMAND

2000 13.3 MGD
2010 14.0 MGD

YEAR DEMAND
1990 21.6MGD
2000 22.6 MGD
2010 23.8 MGD
MGD = million gallons per day
5
Total future groundwater production will reach approximately 17.7 MGD
within 2 to 3 years. Although it appears that current and future maximum day
demands will not be supplied, reservoir storage facilities are planned which will
provide the necessary additional supply in times of peak demand.
TWS will not place any new facilities into service within 12 months (by
January, 19931. therefore Ordinance No. 1060 would be invoked in times of
extreme shortage.
Within 24 months (January, 1994) it is anticipated that supply from at least
1 new well will be available, and Ordinance No.1 063, or the less restrictive stages
of Ordinance No.1 060 will result in adequate reductions in ùse.
It is anticipated that within 36 months (January, 19951. with planned
improvements in place, it is unlikely that shortages will exist within the TWS
system.
Section 10631 (e)(3) of the Act requires: "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."
The City's Ordinance No.1 060 delineates the stages of action that will be
taken if up to a 50 percent reduction in water supply occurs. Ordinance No.1 063,
which established a Mandatory Water Conservation and Rationing Program to
reduce consumption by 15 percent, was adopted by City Council on April 1, 1991
and remains in effect.
6
The MWD Plan in Chapter IV, and MWDOC, have also outlined stages of
action in their water shortage contingency plans.
Section 10631 (e)(4) of the Act requires: "Mandatory provisions to reduce
water use which include prohibitions against specific wasteful practices, such as
gutter flooding."
Mandatory provisions to reduce water use have been outlined in detail in the
City's Ordinance No. 1060, and in the MWD and the MWDOC Water Shortage
Contingency Plans.
Section 10631(e)(5) of the Act requires: "Consumption limits in the most
restrictive stages. Each urban water supplier may use any type of consumption
limit in its water shortage contingency plan that would reduce water use and is
appropriate for its area. Examples of consumption limits that may be used include,
but are not limited to, percentage reductions in water allotments, per capita
allocations, an increasing block rate schedule for high usage of water with
incentives for conservation, or restrictions on specific uses."
Stage VI of the MWDOC Incremental Interruption and Conservation Plan
(IICP) requires a 50 percent reduction in imported water usage by TWS.
TWS projects that even with the loss of half of its import supply, it can
meet the demands of its customers provided Ordinances Nos. 1060 and 1063
remain in place. Ordinance No.1 063 calls for a mandatory 15 percent reduction
of water supplied to its customers. A chart noting consumption limits is also
included. Should additional reduction in the water supply become necessary, the
7
TWS would request that the City Council invoke the most appropriate stage of
Ordinance No.1 060.
Section 10631 (e)(6) of the Act requires: 'Penalties or charges for excessive
use,"
Additional charges and penalties are outlined in the Citys' Ordinance Nos,
1060 and 1063, and in the MWD and the MWDOC Water Shortage Contingency
Plans.
Section 10631 (e)(7) of the Act requires: "An analysis of the impacts of the
plan on the revenues and expenditures of the urban water supplier, and proposed
measures to overcome those impacts, such as the development of reserves and
rate adjustments."
The water rate is a combination of fixed rates and water usage charge, The
fixed portion of the rate, which is comprised of customer service, meter demand,
debt service, and multiple dwelling unit charges, is designed to recover fixed
operating costs and 75% of funding for the Capital Improvement Program. The
water usage charge is designed to recover the costs of purchasing/producing water
and 25% of funding for the Capital Improvement Program, The probable response
to a 50% water shortage would be to reduce or defer capital spending.
Section 10631(e)(8) of the Act requires:
"A draft water shortage
contingency resolution or ordinance to carry out the urban water shortage
contingency plan."
8
A draft water shortage contingency plan Resolution No. 92-15 and
Certification for said resolution is included in the Appendix of this Plan.
Section 10631(e)(9) of the Act requires: "A mechanism for determining
actual reduction in water use pursuant to the urban water shortage contingency
plan."
TWS maintains monthly water production statistics by source. It utilizes
this information to monitor its water conservation program. Samples of reports
have been included in the Appendix for your reference.
Section 10631 If) of the Act requires: "To the extent feasible, describe the
method which will be used to evaluate the effectiveness of each conservation
measure implemented under the plan."
The TWS will use the data as specified in Section 1 0631(e)(9) to evaluate
the effectiveness of each element of its water conservation plan.
Section 10631 (g) of the Act requires: "Describe the steps which would be
necessary to implement any proposed actions in the plan."
The steps necessary are outlined in Ordinance Nos. 1060 and 1063, and in
Resolution No. 92-15.

SECTION 1.
Water consumption Reduction.
7
A. Findinqs. The city Council hereby finds and determines
as follows: the State of California is entering the fifth year of
an unprecedented drought; water levels at many reservoirs are at an
all time low; deliveries of water to the Southern California region
from the State Water Project, Colorado River, Owens Valley and Mono
County have declined due to the lack of rainfall and litigation
regarding entitlement; the Metropolitan Water District of Southern
california (MWD) is the supplier of thirty percent (30%) of the
water supplied to the Tustin Water Service and MWD has reduced the
city's allocation of water by thirty percent (30%) as of March 1,
1991 and advised that it will charge the City a premium of at least
'Thrèe Hundred Ninety-Four Dollars ($394) per acre foot for delivery
of water in excess of new allocation. levels; the Mandatory
Conservation Rate on the effective date of this ordinance is a
collective fifteen percent (15%) ; this Conservation Rate
corresponds with the recent decision of MWD .to allocate only
seventy percent (70%) of the water used. by the City during
. comparable periods in the past; the failure 'of Tustin Water service
consumers to collectively reduce water consumption may lead to even
more drastic. cutbacks in allocations, deliveries, and costs; the
failure to reduce water consumption and a continuation of the
drought may, in the long term, result in the inability of. the City
to supply water at or above minimum levels required for health and
sanitation; this ordinance will promote reductions in water
consumption and permit recovery of additional costs incurred with
the purchase of water and the administration of water conservation
measures.

the adequacy of the grounds of reli~f or a finding that maximum
practical reduction and consumption has been achieved:
3. The decision of the city Manager or designee shall

22
23
24
25
26

16
SECTION 2. The City council finds and declares that adoption
of this ordinance as an emergency measure is necessary to preserve
the public peace, health, and safety in that: .
17
18
A. California is currently experiencing a drought of
unprecedented magnitude with current water reserves throughout the
State far below normal.
19
20
.. B. The city has initiated a voluntary water conservation
program, but the program has not achieved the desired results.
21
c. Metropolitan Water District, the supplier of imported
water to the city of Tustin, has announced its intention to reduce
the amount of water delivered to the city and to impose a surcharge
on all water sold to the City in excess of new allocation levels.
The surcharge and reduced allocation levels were effective on
February 1, 1991 and compliance with MWD directives cannot be
achieved other than through the adoption of an emergency ordinance.
22
23
24
25
D. The imposition of penalties on excess consumption of
water will reduce water usage and allow the city to recover the
additional costs it incurs relative to the purchase of water from
MWD.
26
27
28
Ordinance No. 1063, Page 6
1
2
E. Failure to achieve a fifteen percent (15%) reduction in
water consumption will reduce available water supplies, lead to
further MWD mandated reductions,. and require imposition. of more
stringent restrictions on water use in the future. In the long
term, the failure to conserve water combined with continued drought
could lead to the inability of the city to provide water in amounts
necessary for health and sanitation.

CHAPTEH --
An act to amend Sections 10620, 10621, 10631, and 10652
of, and to add Section 106.56 to, the Water Code, relating
to water.
LEGISLATIVE: COl't\SEL'S DIC¡¡:ST
AB 11, Filante. Urban water management plans.
(1) Existing law requires every urban water supplier
serving water directly to customers to, not later than
December 31, 1985, prepare and adopt an urban water
management plan. Existing law authorizes an urban
water supplier indirectly providing water to customers to
adopt an urban water management plan or to participate
in urban water management planning.
This bill would, instead, require every urban water
supplier, whether serving water directly or indirectly to
customers, to prepare and adopt an urban water
management plan, as prescribed.
(2) Existing law requires the urban water
management plan to include a prescribed description of
water supply deficiencies.
This bill would delete that provision and would require
the urban water management plan to include an urban
water shortage contingency plan, as specified. The bill
would require each urban water supplier to coordinate
the preparation of its urban water shortage contingency
plan with other urban water suppliers and public
agencies in the area to the extent practicable. The bill
would require each urban water supplier, not later than
January 31, 1992, to prepare, adopt, and submit to the
Department of Water Resources an amendment to its
urban water management plan which meets the
requirements relating to the preparation of the urban
water shortage contingency plan. The bill would make an
urban water supplier that does not submit the
amendment by that date ineligible to receive drought
assistance from the state until the urban water
management plan is submitted, as prescribed.
(3) Existing law exempts the preparation and
<D
95 90
-3-
AB 11
adoption of urban water management plans from the
California Environmental Quality Act. .
This bill would exempt the implementation of urban
water shortage contingency plans from that act. The bill
would provide that the exemption provisions do not
exempt specified projects from the requirements of that
act.
The people of the State of CaliFornia do enact as Follows:
SECTION 1. Section 10620 of the Water Code is
amended to read:
10620. (a) Every urban water supplier shall prepare
and adopt an urban water management plan in the
manner set forth in Article 3 (commencing with Section
10640).. .
(b) Every person that becomes an urban water
supplier after December 31, 1984, shall adopt an urban
water management plan within one year 'after it has
become an urban water supplier.
(c) An urban water supplier indirectly providing
water shall not include planning elements in its water
management plan as provided in Article 2 (commencing
with Section 10630) that would be applicable to urban
water suppliers or public agencies directly providing
water, or to their customers, without the consent of those
suppliers or public agencies.
(d) (1) An urban water supplier may satisfy the
requirements of this part by participation in areawide,
regional, watershed, or basinwide urban water
management planning where those plans will reduce
preparation costs and contribute to the achievement of
conservation and efficient water use.
(2) Each urban water supplier shall coordinate the
preparation of its urban water shortage contingency plan
with other urban water suppliers and public agencies in
the area, to the extent practicable.
(e) The urban water supplier may prepare the plan

review its plan at least once every five years. After the
review, it shall make any amendments or changes to its
plan which are indicated by the review. Amendments or
changes in its plan shall be adopted and filed in the
manner set forth in Article 3 (commencing with Section

commercial, and governmental uses.
(b) Identify conservation measures currently adopted
and being practiced.
(c) Describe alternative conservation measures,
including, but not limited to, consumer education,
metering, water saving fixtures and appliances, lawn and
garden irrigation techniques, and low water use
landscaping, which would improve the efficiency of
water use with an evaluation of their costs and their
environmental and other significant impacts.
(d) Provide a schedule of implementation for
proposed actions as indicated by the plan.
(e) Provide an urban water shortage contingency plan
which includes all of the following elements which are
within the authority of the urban water supplier: .

worst case water supply shortages.
(3) Stages of action to be undertaken by the urban
water supplier in response to water supply shortages,

include prohibitions against specific wasteful practices,
such as gutter flooding.
(5) Consumption limits in the most restrictive stages.
Each urban water supplier may use any type of
consumption limit in its water shortage contingency plan
that would reduce water use and is appropriate for its
area. Examples of consumption limits that may be used
include, but are not limited to, percentage reductions in
water allotments, per capita allocations, an increasing
block rate schedule for high usage of water with
incentives for conservation, or restrictions on specific
uses.
(6) Penalties or charges for excessive use.
(7) An analysis of the impacts of the plan on the
revenues and expenditures of the urban water supplier,
and proposed measures to overcome those impacts, such
as the development of reserves and rate adjustments.
(8) A draft water shortage contingency resolution or
ordinance to carry out the urban water shortage
contingency plan.
(9) A mechanism for determining actual reductions in
water use pursuant to the urban water shortage
contingency plan.
(f) To the extent feasible, describe the method which
will be used to evaluate the effectiveness of each
conservation measure implemented under the plan.
(g) Describe the steps which would be necessary to
