URBAN WATER MANAGEMENT PLAN
CHAPTER I
INTRODUCTION
1.1 OVERVIEW
This plan has been prepared in accordance with the Urban Water Management Planning
Act (UWMPA) of 1983 or California State Legislature Assembly Bill 797 (AB -797).
AB -797 requires every urban water supplier providing water for municipal purposes to
more than 3,000 customers or supplying more than 3,000 acre-feet of water annually to
prepare and adopt, in accordance with prescribed requirements an urban water
management plan containing prescribed elements. This bill also requires the plan to be
filed with the State of California Department of Water Resources (DWR).
The City of Tustin Water Service (TWS), in compliance with UWMPA, has prepared
the following Urban Water Management Plan (UWMP). The objective of the City's
UWMP is to: (1) Provide information relative to past, current, and projected water use;
(2) Identify conservation measures currently adopted and being practiced within the
City's service area; (3) Describe alternative conservation measures which would improve
the efficiency of water use; (4) Provide a structured framework for the implementation
of such a plan; and (5) Describe the frequency and magnitude of supply deficiencies in
conditions of drought. This plan complements portions of the Metropolitan Water
District of Southern -California (MWD), Municipal Water District of Orange County
(MWDOC), and the Orange County Water District's (OCWD) Water Management Plans.
Reference has also been made to the County Sanitation Districts of Orange County (CSD)
Action Plan for Wastewater Management (April 1989).
The chapters in this plan correspond to the elements as required in Article 2, Sections
10631 and 10632 of AB -797, although the sequence may differ in order to present the
material in a manner reflecting the characteristics of the City of Tustin water service
area.
1.2 CITY OF TUSTIN WATER SERVICE BACKGROUND
The City of Tustin Water Service (TWS) was purchased from the Tustin Water Works
in October 1980. TWS provides domestic and fire protection water service to most of
the incorporated area of the City of Tustin and also to a portion of the unincorporated
area of the County of Orange to the north of the City.
1-1
TWS received approximately 60 percent of its water from underlying groundwater in the
Santa Ana River Basin through its nine operational wells and about 40 percent from
import water purchased from MWD, through MWDOC and the East Orange County
Water District (EOCWD) in 1989-90. It is anticipated that in future years the ratio will
be 70 percent groundwater to 30 percent import water. Water is imported through seven
MWD turnouts located at various locations throughout the TWS distribution system.
Figure 1.1 shows the boundaries of the TWS, the EOCWD, and the three water system
pressure zones.
The groundwater basin is managed by the OCWD, who determines each year the
percentage of the City's water demand that can be taken from the basin. This is called
the Basin Production Percentage (BPP). The BPP for the TWS is 70 percent, however
any water produced from its treatment plants is exempt from this percentage. The impact
of this treated water will be discussed later in this plan.
Over the past several years, the City of Tustin 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
emergency storage. Future studies will be made of the TWS transmission and
distribution system to increase its reliability and provide a better quality water to meet
the needs of its growing number of customdrs.
Additional TWS general information can be found in the Appendix.

CHAPTER 2
PAST, CURRENT AND PROJECTED WATER USE
Section 10631(a) of AB -797 requires that the plan contain an estimate of past, current,
and projected water use segregated between residential, industrial, commercial, and
governmental uses. Unfortunately, the City of Tustin does not have its water usage
separated into the above groups. It will take several months to gather the data necessary
to complete this portion of the plan. Once this information has been collected, an
addendum to this plan will be prepared and submitted to DWR.
2.1 WATER SOURCES
The TWS currently has in operation nine deep water wells. Although the City is entitled
to 70 percent of its total yearly production from less expensive groundwater, it was able
to pump only about 60 percent in 1989-90. This is primarily a result of the deactivation
of five wells due to water quality problems, and the lack of constructing new wells to
keep pace with increasing demand. Figure 2.1 contains data for the TWS wells.
The other 40 percent of the City's water is supplied through seven EOCWD import
connections located throughout the TWS service area. Water supplied to EOCWD is
outlined in the MWDOC and MWD Urban Water Management Plans. Figure 2.2 shows
import connection data.
Typical annual and monthly water production along with additional Tustin Water Service
data is provided on Figure 2.3.
2.2 PAST WATER USE
Water demand, in general, is affected by population densities, climatic factors ' and
temporal variations based on characteristic behavior of the public. The average daily per
capita demand is a useful criteria for evaluating the historic water demands for an area
as well as projecting future water demands in conjunction with population and planning
area projections. The per capita consumption figure represents the overall average water
use pertaining to residential, industrial, commercial, and governmental demands; as well
as any losses within the water distribution system.
It is difficult to accurately estimate the population within the TWS service area. The
TWS serves county areas outside the City limits to the north and another water agency,
Irvine Ranch Water District, provides water service for the eastern part of the City.
Portions of Tustin's service area has either been purchased or sold to other water
purveyors, therefore historical data is inaccurate. Once segregated water service data
becomes available, a more reliable service population figure can be estimated and used
in this plan.

Figure 2.3
Past TWS water usage is shown in Figure 2.4. It appears from this data that TWS
customers do in fact conserve water in years of drought, as seen in decreasing water
usage during 1976 and 1977, and also from 1987 and 1989.
2.3 CURRENT AND PROJECTED WATER USE
From data collected by the City of Tustin, it has been estimated that water usage in 1990
is down between five and seven percent compared to the amount used in 1989 with the
TWS service area. This decrease may be a result of steps taken throughout 1990 to
educate the public in water conservation. These measures will be discussed in Chapter
4 of this plan.
Projected water use, as shown in Figure 2.4, are a result of an anticipated population
growth within the service area of five percent every ten years through the year 2010.
The 1990 service area population has been estimated at 70,500. Based on a water
demand of 180 gallons per capita per day, water usage was projected to the year 2010.
The above information was derived from Chapter 6 of a recently completed City of
Tustin Water System Storage Evaluation Study dated October 19, 1990.

CHAPTER 3
WATER SUPPLY DEFICIENCIES AND RESPONSE
Section 10631(e) of AB -797 requires that the UWMP include a description of the
frequency and magnitude of supply deficiencies, including conditions of drought -and
emergency, and the ability to meet short-term deficiencies. Possible water supply
deficiencies and response have been addressed in Chapters III and 3 of the MWD and
MWDOC Urban Water Management Plans, respectively.
3.1 SUPPLY DEFICIENCIES
The TWS has no current source of supply deficiencies. However, with the possibility
of a continued drought period, MWD storage supplies may be affected. MWD shortages
or mandatory cutbacks could reduce the amount of water it delivers to its customers.
There is also the potential for failure of the City's existing wells due to age and/or water
quality considerations. The addition of new TWS supply wells and storage reservoirs
would reduce the City's dependance of MWD import water in times of severe drought
periods or interruption of supply. The City of Tustin is currently working in this
direction. TWS short-term deficiencies may also be made up through the use of its
emergency connections with other agencies, should they have the water available. These
connections are outlined in Chapter 7 of this plan.
3.2 VOLUNTARY WATER CONSERVATION MEASURES
The City has taken increasing steps in the last few years to educate its customers in water
conservation. News releases, distribution of brochures, and water conservation
resolution ordinances have been adopted by the Tustin City Council. These measures
will be discussed further in Chapter 4 of this plan.
3-1
CHAPTER 4
CURRENT WATER CONSERVATION PROGRAMS
Section 10631(b) of AB -797 requires identification of conservation measures currently
adopted and being practiced. Chapter VI of MWD's and Chapter 4 of MWDOC's Urban
Water Management Plans, contain their current water conservation programs.
4.1 GENERAL PUBLIC INFORMATION
The City of Tustin has made available to its customers numerous water conservation
related brochures and pamphlets. This material covers such topics as; (1) Drought
tolerant landscaping (Xeriscape); (2) Ways to save water around the house (inside and
out); (3) California water supplies and management practices; and (4) The Guzzler
Gang, a cartoon pamphlet illustrating water wasters around the house. Water
conservation kits were also made available.
Several press releases have been sent to numerous local news agencies and groups. A
direct mailing to restaurants encouraging them not to serve water to any customer, except
upon request, was made. Water billing messages frequently inform TWS customers of
continuing drought conditions and of water conservation ideas. The City of Tustin will
continue to provide its customers with the above information. Samples have been
provided in the Appendix of this plan.
4.2 LEAK DETECTION AND MAIN REPLACEMENT PROGRAM
No leak detection program is required in the TWS service area. Soil conditions are such
that any substantial leak would be identified and repaired immediately to conserve water
and to mitigate any further damage or hazard to the area.
The City has an ongoing Capital Improvement Project (C.I.P.) program which is
replacing older deteriorated water mains. This program not only reduces water loss due
to elimination of mains prone to leaking, but pumping energy costs can be reduced
through the use of a new lower friction loss pipe. The TWS has approximately 81,500
feet of main remaining in its system that is scheduled for replacement. It is anticipated
that this program will be completed within five years. A list of those water mains
scheduled for replacement are shown on Figure 4.1.
4.3 CITY LANDSCAPING AND IRRIGATION PRACTICES
Recent City of Tustin median designs have reflected a reduction in the amount of turf
area and also utilize an inward sloping perimeter to retain water. Many median lawns
have been replaced with decorative stamped concrete.

Moisture sensors have been installed on all City park and median irrigation systems. It
is estimated that these sensors have reduced water consumption by 12 percent.
Irrigation systems are monitored and adjusted constantly to guard against overspray. If
a system is found to be water wasteful, it is repaired, modified or replaced.
Drought resistant landscaping is used wherever possible to reduce water consumption.

CHAPTER 5
ALTERNATIVE WATER CONSERVATION PROGRAMS
Section 10631(c) of AB -797 requires a description of alternative conservation measures
which would improve the efficiency of water use. The TWS supports those alternative
water conservation programs as outlined in Chapter VIII of the MWD plan and Chapter
5 of the MWDOC plan. Additional City of Tustin measures are as follows.
5.1 HOME RETROFIT OF PLUMBING
The retrofitting of household plumbing with low flow fixtures, including low flow toilets
is encouraged through educational material and news releases. No City ordinance
currently exists which mandates the use and installation of these water saving devices.
This water conservation measure will be considered in future years.
5.2 OUTREACH PROGRAMS
The City is working towards the development and implementation of outreach programs
designed to identify high water consumption and to be responsive to broken sprinklers
and water misuse when so advised by its' customers. A TWS representative will
investigate such reports; and if water misuse is found, an informational packet is sent to
that customer explaining the need for conservation. This packet contains water
conservation tips, landscaping ideas, and a water conservation kit. This program will be
in place within the next few months._
5.3 WATER AUDITS
No water audit program exists at the present time. The City does not have the staff
available to conduct a door-to-door audit. One alternative being considered, is to mail
a water usage questionnaire to its customers which would obtain results similar to a water
audit. This survey could be mailed out and returned with water bills.
5.4 CONSERVATION ORDINANCES
The City is currently looking into the implementation of a program similar to that
adopted by MWD. This five staged program, known as the Incremental Interruption and
Conservation Program (IICP), establishes water conservation objectives for local agencies
ranging from a voluntary 10 percent reduction in purchases from MWD at Stage I,
through a mandatory 20 percent reduction in purchases from MWD at Stage V.
This proposed ordinance would give the City an additional tool with which to achieve
greater conservation and would allow the City Manager, with Council ratification, the
flexibility to adjust to any rapidly changing water supply situation. This ordinance would
5-1
be organized into four stages, ranging from Stage 1, Voluntary Compliance, to Stage 4,
Water Emergency. It would provide for penalties ranging from a written warning
through a temporary cutoff of service in cases of severe abuse. The ordinance would
also provide for imposition of a tiered rate structure in uses of water abuse. This will
need to be further detailed and approved by Council prior to implementation, and once
approved would require an additional three to six months to be installed in the current
utility billing system.
5-2
CHAPTER 6
WASTEWATER RECLAMATION
Section 10632(a) of AB -797 requires urban water suppliers to evaluate the potential for
producing additional water supplies from wastewater reclamation activities. Wastewater
in the TWS service area is transported and then treated by the County Sanitation Districts
of Orange County (CSD) at their facilities in Fountain Valley and Huntington Beach.
Wastewater reclamation is outlined thoroughly in CSD's April 1989 Action Plan for
Wastewater Management, and also in Orange County Water District's (OCWD)
Groundwater Management Plan and MWDOC's Urban Water Management Plan.
6.1 GROUNDWATER TREATMENT PLANTS
The TWS is currently operating a Demonstration Treatment Plant (DTP) which reduces
the concentration of nitrates from two water wells located at its Main Street Plant. This
treatment plant was constructed by OCWD to remove high level nitrate water from the
groundwater basin and also to give TWS an. additional source of supply. The treatment
operation uses two separate processes. High nitrate water produced by Well No. 3 is
treated using either reverse osmosis (RO) and ion -exchange (IX) which work in parallel.
The product water is blended with a lower nitrate water from Well No. 2 and is then
pumped into the distribution system. Approximately 2400 acre-feet per year is being
produced from water once unusable due to its poor quality. A similar DTP is expected
to be constructed and operational by 1993. It will treat water with excessive
concentrations of nitrates and total dissolved solids (TDS) and is expected to produce
approximately 3,000 acre-feet annualfy. Figure 6-1 illustrates the production of treated
groundwater verses the total TWS water demand (supply). The data shown from 1990
to 2010 are projections from information in Chapter 2.

CHAPTER 7
EXCHANGE AND TRANSFERS OF WATER
Section 10632(b) of AB -797 requires urban water suppliers to explain and evaluate their
plans for future exchanges or transfers of water on a short-term or long-term basis.
7.1 EXCHANGES AND TRANSFERS
Water transfers to TWS are made through EOCWD metered connections. No changes
in this arrangement are anticipated in the immediate future. No ongoing exchanges or
transfers of water with other agencies are currently being made, except in times of
emergency. Intercounty and intracounty exchanges and transfers are discussed in
Chapters 7.0 and IV of MWDOC's and MWD's Urban Water Management Plans,
respectively.
7.2 INTERCITY TRANSFERS
The TWS has five emergency connections (interties) with other water agencies. These
bidirectional interties, which are listed below, provide a short-term emergency water
supply to meet the TWS needs as well as those of the adjacent agency.

MANAGEMENT OF SYSTEM PRESSURE AND PEAK DEMANDS
Section 10632(c) of AB -797 requires the management of water system pressures and peak
demands. MWDOC's management practices are described in Chapter 8 of its' UWMP.
8.1 SYSTEM PRESSURE MANAGEMENT
The TWS has three pressure zones. Pressures in these zones range from 30 to 110 PSI.
The City monitors the zones daily to protect against excessive pressures which could
cause leaks in the system.
8.2 PEAK DEMAND MANAGEMENT
Water system demand patterns are a result of climatological, land use, sociological, and
institutional factors, all of which affect the amount of _ water consumed. Water
conservation can reduce peak demands and thus reduce the need for construction of new
storage and distribution facilities and, in certain instances, the development of new water
sources.
The TWS currently is able to meet peak water demands. However, should import supply
continue to be reduced and demand increases as shown in Chapter 2, the TWS will be
unable to meet its' customer needs without the construction of new wells and reservoirs.
The TWS is in the process of installing a Supervisory Control and Data Acquisition
(SCADA) system. SCADA will be used to monitor and control TWS's system, including
pressures. This telemetry system will also be capable of collecting and storing data that
will provide water management information and will be useful in the City's water
conservation effort.

CHAPTER 9
PRICING, RATE STRUCTURES, AND REGULATIONS
Section 10632(f) of AB -797 requires urban water suppliers to evaluate water conservation
through changes in pricing, rate structures, and regulations. Chapter VII in MWD's and
Chapter 9 of MWDOC's Urban Water Management Plans provide an overview of these
measures.
9.1 PRICING AND RATE STRUCTURE
The rate structure was established as recommended in a Water System Financial Review
and Rate Study completed by James J. Montgomery Consulting Engineers, Inc. in
October, 1982.
Through this structure TWS established a bimonthly billing cycle where all meters are
read on a bimonthly cycle. The rates contain a fixed, charge which is partially
determined by the meter size. This charge also includes system maintenance and
administration costs and a factored amount to retrieve the water service debt in a timely
manner.
The water use charge was determined by TWS's cost of pumping and purchasing water,
plus projected costs of future system improvements. Included as part of the overall
consumption rate is an allowance for a basic lifeline consumption at a reduced rate to
ensure that all customers of the system have access for basic needs.
The TWS rate structure was adjusted by Resolution No. 83-7 on January 17, 1983. A
copy of this Resolution illustrating the water rate structure, along with water rate history
and service charge summary, have been provided in the Appendix. Figure 9.1 provides
TWS water cost information for 1989-90.

CITY COUNCIL URGES CUTBACK IN WATER CONSUMPTION
i Since rainfall for the past four consecutive years has been
+ substantially below normal, particularly in the water shed areas
serving Southern California, the California Department of Water
Resources has declared 1990 to be a c-ritically dry year.
The Municipal Water District of Orange County has requested
every water supplier within its service area to alert its customers
to the necessity and means of saving water. Complying with this
request, the Tustin City Council has adopted a voluntary water
conservation program, with a goal of reducing water consumption by
10 percent, in order to reduce the risk and severity of water
shortages should the drought continue.
The City is suggesting all consumers follow these water use
guidelines:
* Adjust sprinklers and irrigation systems to avoid over -spray,
run-off and waste;
* Avoid watering in the
hot
part of
the day and
during morning
and evening peak hours
( 6
to 9 a - m.
and 4 to 8
p.m.) and avoid
watering on windy days;

A LOCAL NEWS PUBLICATION)
WATER CONSERVATION UPDATE
The start of 1991 brought the fifth consecutive year of a drought
to California. This has reduced the potential water supply for
Southern California and may cause higher costs on imported water
for many Orange County cities. The City of Tustin extracts fifty
eight (58) percent of its water from our wells, and relies on
imported water for approximately forty two (42) percent of our
water. While Tustin is better prepared for the effects of the
drought than other areas, it is essential that we continue to
conserve water. Thanks to your continued water conservation efforts
water usage is down by eight (8) percent, since May 1990 when the
City Council passed a resolution asking for voluntary water
conservation.
SAVE WATER AND MONEY BY:
- Washing only full loads of laundry or dishes.
- Tightening faucets and replacing worn washers.
- By installing a low flow faucet aerator you can
reduce the flow by 50% and still maintain the same
strong flow because air is mixed into the water as
it leaves the tap.
- Water Conservation Kits are available by calling
the Water Billing division at (714) 544-8890.

City of Tustin
Department of Finance
Dear Restaurant Owner;
The State of California's drought situation has been in the news
a lot lately, and there has been conflicting statements about its
effect on Orange County. The truth is that historically, the City
of Tustin has utilized its own wells to extract fifty eight (58)
percent of our water, and has relied on imported water for
approximately forty-two (42) percent of our water. Because to some
extent we do rely on imported water from many sources, it is
important that we also do our part to conserve water.
The City of Tustin is -encouraging restaurants in Tustin not to
serve drinking water to any customer except upon request. Enclosed
please find table tents for your tables to explain this situation.
We would appreciate any assistance you may give us in our
conservation efforts.
If you have any questions or if you would like further information,
please contact Irma Hernandez at 544-8890, extension 262.
Thank you in advance for your assistance.
Sincerely,
Ronald A. Nault
Director of Finance
