AGENDA TITLE: Continue Public Hearing to Consider Adoption of the Updated Urban Water
Management Plan
MEETING DATE: May 1, 1996
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council conduct a public hearing on and adopt Lodi's
Urban Water Management Plan.
BACKGROUND INFORMATION: During the 1983-84 Regular Session, the California Legislature
enacted Assembly Bill 797, which, with subsequent amendments,
created Water Code Section 10610, et seq., the Urban Water
Management Planning Act. This Act requires the City of Lodi to
review and update the Urban Water Management Plan every five years. This will be the second update
of Lodi's Urban Water Management Plan. The adoption process requires a public hearing and adoption
by the City Council.
The attached Plan updates Lodi's historical and projected population and water use, water rates, and
water metering program status. The Plan's format was also changed to reflect the same format the State
uses.
Substantive changes from the previous plan include a discussion of the Conjunctive Use project
negotiations between eastern San Joaquin County water users and EBMUD (Page 5 and Exhibit L), and
current water reclamation/recycling projects at the City's wastewater treatment facility (Page 11 and
Exhibit Q).
A copy of the updated Urban Water Management Plan (approximately 75 pages) is available in the
City Clerk's Office for those parties who did not receive the plan with this communication.
FUNDING: None required.

URBAN WATER MANAGEMENT PLAN
CITY OF LODI, CALIFORNIA
Updated March 15, 1996
Amended and Adopted 1996
SECTION 1
PLAN ADOPTION AND PUBLIC HEARING
This update of the Urban Water Management Plan for the City of Lodi has been prepared in compliance
with California Water Code Sections 10610 -(et Seq.). This section of the California Water Code
requires that all urban water suppliers providing water for municipal purposes either directly or
indirectly to more than 3,000 customers, or supplying more than 3,000 acre-feet or water annually, must
prepare an Urban Water Management Plan and update it at least every five years.
As required by regulations, a public hearing on the updated Urban Water Management Plan was set for
April 17, 1996 Lodi City Council meeting (Exhibit A). However the hearing was held over to the May
1, 1996 Lodi City Council meeting. This updated Urban Water Management Plan was available for
public viewing before the public meeting.
This updated Urban Water Management Plan was adopted by the Lodi City Council on May 1, 1996.
The updated Urban Water Management Plan is required to be submitted to the California Department of
Water Resources within 30 days of approval.

CITY OF LODI AND `NATER FACILITIES
CITY OF LODI
The City of Lodi, founded in 1906, lies in the Northern San Joaquin Valley in the San Joaquin County.
The City of Lodi, which the City's water system services, encompasses approximately 7,000 acres of
land. The City government is comprised of an elected City Council with the City Mayor elected from
the City Council members. The City of Lodi's potable water supply is 100% groundwater. Currently
there are approximately 55,000 residents and approximately 21,200 water customer connections.
The climate is Mediterranean with warm, dry summers and wet, foggy winters. The rainfall averages
approximately seventeen inches per year which falls mainly from October through April. The City is
bordered to the north by the Mokelumne River.
WATER UTILITY
The City of Lodi's potable water supply is 100% groundwater. Currently there are 23 active production
wells and one on emergency standby status. Exhibit B gives the name, location and capacity of the City
wells. Exhibit C is a map showing the City's Water service area and the City well locations. One new
well and a new 1 -million -gallon water storage tank are proposed for 1996-97. The City of Lodi water
system operates under permit from the California Department of Health Services. The permit was
renewed in 1995.
Residential water users and 28% of all non-residential water users are unmetered, therefore any
segregation between users can only be estimated. Approximately 72% of the City of Lodi's potable
water use is by residential customers, 28% by commercial/industrial and governmental customers,. and
less than 0.01% for agriculture. Exhibit D contains the above data.
Lodi has enforced the City's Water Conservation Ordinance Regulations since 1977. Water
Conservation in Lodi is supported by the City Council and as a continuing program, has earned the
GAA WW\URBWP95E.DOC 2 May 1, 1996 Public Hearing Draft
support of Lodi's citizens. The latest revisions to Lodi's current Water Conservation Ordinance
(Exhibit E) were in 1991.
Lodi's Water Conservation Ordinance has had great success. In 1976, the year before the ordinance was
adopted, Lodi delivered 4.434 billion gallons of water to a population of 32,150; averaging 378 gallons
per capita per day (gpcpd). In 1995, the City delivered 4.689 billion gallons of water (a 5.7% increase
from 1976) to a population of 54,694 (a 70% increase), with an average 235 gpcpd (a 38% decrease).
These gpcpd figures use total water production, including all industrial and commercial uses, which is
then divided by the population. Lodi's Water Conservation Program is discussed in detail later.
The City's General Plan Update which establishes a 2% growth rate, was approved by the City Council
in 1991. Lodi's population growth over the past five years has been approximately 1.75% per year.
A State Department of Health Services regulated volatile organic compound, the banned agricultural
pesticide Dibromochloropropane (DBCP), is present in approximately five wells at levels requiring
treatment. Four wells are currently set up for treatment with Granulated Activated Carbon filtration
systems and the fifth well is on emergency standby status. For further information on Lodi's drinking
water system and drinking water quality, the June 1995 Annual Water Quality Report to Customers is
attached as Exhibit F.
NATER METERS
The City has been installing meters on all new commercial and industrial customers since 1977_ The
City had been retrofitting existing commercial and industrial users with water meters. until the Lodi City
Council discontinued the program in 1994 to "save money". Of the approximately 1,235 commercial
water customers, approximately 347 remain unmetered.
Since January 1, 1992, all "new water service connections" were to be metered per California law. The
City currently sets a meter box and collects fees for the installation of a water meter on all "new water
service connections". However, the meters are not installed because Lodi does not have residential
meter rates established nor the personnel authorized to read the residential meters. The meters will be
G:1WVMURBWP95E.D0C 3 May 1. 1996 Public Hearing Draft
installed when residential metered rates are established and the necessary personnel are authorized to
read the meters. Exhibit G is a copy of the Lodi City Council approved Resolution No. 95-28 endorsing
this approach.
WATER RATES
Water rates were modified effective June 1, 1995. The new rates are compared to the former rates in
Exhibit H. The new rates have encouraged conservation for the metered water user by eliminating the
former water allowances. The former water allowances gave metered users an amount of water
included in the base meter rate before any additional charges for water were in effect. For example, a
metered water user with a one inch meter was allowed over 40,000 gallons each monthly metering
period before water unit charges were in effect. Additionally the flat rate commercial customers now
pay a higher monthly flat rate than the base rate charged for a metered service.

SECTION III
WATER USE, WATER SUPPLY OUTLOOK, CONJUNCTIVE USE
PAST, CURRENT, AND PROJECTED WATER USE
An attached chart (Exhibit I) shows the historical total water production and compares this to the
respective populations as gallons per capita per day (gpcpd). The projected population and water use is
in Exhibit J. Two projections are given using growth rates of 1.5% and 2.5% and water demands of 235
gallons per capita per day (gpcpd) and 270 gpcpd respectively.
PAST, CURRENT, AND PROJECTED WATER SUPPLY
The historical drop in the groundwater, 1962 through 1995, has been approximately six inches per year.
However, during the drought conditions of 1986 through 1992 ground water levels dropped a total of
12 feet, or an average of 2 feet per year. Some of the City wells pump bowls have had to be lowered.
Since the 1991-92 season, the area has seen three above-average rainfall seasons and one below-average
rainfall season. Over the past three years, the water table has increased an average of eight inches per
year, or a total of two feet. Exhibit K is a chart showing the historical standing groundwater levels as
measured at Lodi City wells from 1962 through 1995 and historical rainfall data.
While it is projected that the City of Lodi will continue to have an ample groundwater supply, surface
water is also a source Lodi may consider in the distant future (20+ years). Sources of surface water
could be from the Mokelumne River or purchasing water from future water conveyance structures (i.e.,
canals or pipelines) in the Lodi area.
CONJUNCTIVE USE PROJECT
The City of Lodi is actively participating in discussions and negotiations.concerning future water
supplies in the eastern San Joaquin County area. The City is a part of a group of eastern San Joaquin
County water users negotiating a conjunctive use project with the East Bay Municipal Utility District
(EBNIIJD). Attached as Exhibit L is a document, which has been reviewed by the Lodi City Council,
concerning the latest conjunctive use water planning and principles affecting the eastern San Joaquin
County and negotiations with EBMUD.

SECTION IV
NATER CONSERVATION PROGRAM
WATER CONSERVATION PATROL
The City has had an ordinance for water conservation (Exhibit E) since the drought of 1976-77 and has
developed into one of the most comprehensive on-going programs functioning in the San Joaquin
Valley. The program consists mainly of outdoor watering restrictions enforced by water conservation
patrol officers, public education, and an in -school education program.
From 1977 through 1988, a single water conservation officer patrolled during the months of May
through October. Since 1989 three to four water conservation officers have patrolled from May through
October to intensify and enhance the program.
The Water Conservation Patrol Officer's duties are to enforce the provisions outlined in the City
Ordinance., These include prohibition of water waste, provision for dissemination of information and
advice to aid our water customers, and notices of violation issuance for water wasting. An information
sheet (Exhibit M) is given out when water wasting is observed. All violations are recorded on a
violation card (Exhibit N) and filed by address.
The success of Lodi's water conservation program was evaluated in an in-house study. The summary
report of the study is given in Exhibit 0.
IN -SCHOOL EDUCATION PROGRAM
A Water Educational Program was introduced to Lodi elementary schools in 1986. This program
supplements and enhances our total effort to conserve water, as well as other natural resources. In 1986,
four pilot schools were introduced to the program. Presentations have been given in 17 schools,
including four parochial schools, within the Lodi City limits. In 1995, there were 241 classroom
presentations.
GAVWWURBWP95E.DOC 6 May 1, 11996 Public Hearing Draft
The program includes water science demonstration's with the objective of instilling water awareness and
providing information about Lodi's water system and water conservation techniques.
The education program is aimed at grades K through 6th. It is felt to be most cost effective to develop
water awareness and a sense for water conservation while children are most impressionable during their
formative years. A more detailed discussion of the educational program is contained in Exhibit P.
PUBLIC ILNFORMATION/EDUCATION
The City water conservation program participates in four local fairs; the Crime Prevention Fair
(sponsored by Lodi Police Dept.), the Conservation Fair (sponsored by local agencies concerned with
conservation), the Lodi Grape Festival and Harvest Fair, and Earth Day. Staff converses with the fairs'
visitors about Lodi's water conservation program and answers questions they might have concerning
water issues. We also give out information sheets and conservation kits and have had contests for prizes
such as low flow shower heads.
Watering day reminders have been periodically included on the utility bills and on Lodi's cable TV
station throughout the summer months. Newspaper articles and ads are also published throughout the
year in Lodi's and Stockton's newspapers reminding Lodi residents of the water conservation
regulations, offering conservation tips, and relaying the successes of the program. Attractive
refrigerator magnets with the watering day and hour schedules are given out by patrol officers and at the
local fairs.
WATER CONSERVATION KITS
Since 1977, Lodi has distributed water conservation kits (toilet tank displacement bag, dye tablets.and
shower/faucet flow restrictors). These kits are available at no charge through the Water Conservation
Office and at the Finance Department (utility billing).
G:1WW0AURBWP95E.D0C 7 May 1. 1996 Public Hearing Draft
SECTION V
WATER SHORTAGE CONTINGENCY PLAN
PAST, CURRENT, AND PROJECTED WATER USE
An attached chart (Exhibit I) shows the historical total water production and compares this to the
respective populations as gallons per capita per day (gpcpd). The projected population and water use is
in Exhibit J. Two projections are given using growth rates of 1.5% and 2.5% and water demands of 235
gallons per capita per day (gpcpd) and 270 gpcpd respectively.
Due to the fact that residential and 28 % of non-residential water users are not metered, these water
production records cannot easily be broken down into separate types of use. Exhibit D shows the
current estimated breakdown of water usages. The General Plan calls for growth to be approximately
the same in all categories of water users and would therefore coincide with the projections in Exhibit J.
ESTIMATION OF `IINBIUM WATER SUPPLY
The City of Lodi's water supply is 100% groundwater. Although groundwater levels have been
dropping as mentioned above, there seems to be no short-term (12, 24, or 36 months) problems with
water supply. The amount that the groundwater levels could drop in 12, 24, and 36 months would have
a relatively insignificant effect on our ability to obtain the groundwater.
Loss of the capacity to deliver water to the distribution system could occur due to mechanical problems
with wells, pumps, motors, etc. These are the same facing every water supplier. Solutions to these
problems include sound preventative maintenance programs and the ability to make timely repairs when
needed. However, these are not "supply problems" as related to a drought -type situation.
GAW",AURBWP95E.00C 8 May 1, 1996 Public Hearing Dran
STAGES OF ACTION
The City of Lodi will continue the current water conservation efforts including enforcement and
education to conserve the water supply over the long term. Having no residential meters, no supply
problems, and a conservation program that has resulted in per capita water use reductions of
approximately 24% since 1986, we feel there is no need to spend time on developing stages of action
that seem not to be needed nor easy to enforce without residential meters. A 50% loss in "water supply"
would be possible only if 50% of the City Well capacity were down. Again, this would be a
mechanical/operational problem, not an actual water supply problem.
MANDATORY PROVISIONS
There are mandatory provisions already in place. See the Water Conservation Ordinance in Exhibit E.
Further mandatory provisions could include increased restrictions on watering days and hours,
restrictions on washing vehicles, etc., restrictions on large water users, restrictions on flushing of water
lines, restrictions on the filling of swimming pools, and increases in the current penalties for not
complying with water conservation restrictions.
CONSUMPTION LIMITS
Consumption limits cannot easily nor equitably be set because neither residential users nor all
commercial/industrial users are currently metered. The amount of park and landscape irrigation allowed
and a restriction on industrial and large commercial users could be examined in the event of an
emergency.
PENALTIES OR CHARGES FOR EXCESSIVE USE
See the Water Conservation Ordinance in Exhibit E for current charges or penalties. The current
charges could be increased in the case of an emergency.
h'IPACT OF PLAN ON REVENUES AND SPENDING
There is no extraordinary financial impact anticipated on the revenues and expenditures of the City of
Lodi Water Division.

THE CLASSROOM
Philosophy
Using a gut -level hands-on approach that is stimulating to the
class is a prerequisite to accomplishing the objectives to
teaching "Water Science" in the classroom. It must be pertinent
and challenge their imagination.
My previous teaching experience has been at the secondary level.
I believe the elementary level is far more cost effective when
considering lifetime attitudes, values and habits being molded
and established in the most formative period of their lives.
Objective
Instill water awareness and interest particularly among students
in grade levels K thru 6, and the application of this awareness
be utilized in all aspects of water conservation. This is
accomplished by short lectures with students participating and
with several "magic" water shows/experiments that they are
challenged to guess results and to do at home.
Frne-pail ra
The preparation of materials necessary for the particular grade
level must first be selected and organized for presentation. The
materials for the water experiments can be very simple in that
nearly all the ingredients may be found in the kitchen.and most
of the materials can be collected from garbage cans.
This equipment is organized and put into a cardboard box. A two -
wheeled cart is a convenience for wheeling from class to class.
An overhead projector is a must if a transparency is being used:
It is also important when showing water in a medicine dropper,
objects floating on water (seen through a glass plate).
Always arrange to be in the classroom at least five or ten
minutes early to set up and make observations. It is important
to observe student displays on bulletin boards in the classroom
and even in the hallways because often their ideas and current
projects on display can be worked into the water presentation.
1190":0.11 Page 1
Also, if you can initially impress them with your observation; off
their activities they are better conditioned to be receptivq to
your demonstrations.
The initial introduction for a presentation usually includes
distribution of book markers and an OUR WATER brochure. The book
marker has an anti-drug message on one side and a water
conservation message on the other. This presents an opportunity
to reiterate the anti-drug message and present the City of Lodi
message concerning WATER IS LIFE, DON'T WASTE IT. Then the
brochure is briefly discussed. The students are asked to
identify familiar objects and landmarks shown on the front page.
Then they are asked to take the brochure home and maybe play the
same game with their parents, brothers, sisters, or even friends.
It is suggested they encourage their parents to read the
information on the other three pages.
The teacher is given a yard/meter stick for class use. The water
conservation logos imprinted on this ruler is briefly discussed.
Teaching
My presentation always varies in some way, but basically I think
it is best to establish enthusiasm by indicating I play the part
of a magician in performing water tricks. At the same time, they
are informed that there will be no charge for the performance and
all the secrets will be revealed. At this point they are
encouraged to perform at least one of the tricks for their
parents, brother, sister or friend.
Since enthusiasm is so vital for group participation, I
constantly ask questions to see if they can predict the outcome
of each experiment explaining that no one is "wrong" until after
they can see the conclusive proof before their eyes.
One of my favorite lessons is to teach OSMOSIS by using an egg,
potato or fish. If it is a fourth grade class, I use all three.
(These lessons are enclosed)
The message I try to convey is that the water conservation
program is THEIR program. This is where the gut -level approach
is emphasized. By a raise of hands, I have found that about 90%
of elementary students have pets. A simple reminder that if we
didn't have water, all their pets would be dead --is a sobering
thought for all. Another example: By displaying a cross section
of a tree and showing them the tree rings which indicates the age
of a tree as well as dry and wet years is a documentation of
drought periods. Such documentation has shown on very old trees
that from the year 1620 to 1671 there was a fifty year period'of
consecutive drought years. They listen when you suggest the
possibility of this happening in their life time.
Of course such dramatic facts and methods will vary with the
level of the•class I am teaching.
1190wb.11 Page 2
!achers are invariably receptive and interested in the
resentations and nearly always do follow-up on some aspect of
hat I did in their particular class. Many use the experience as
language arts assignment and I have received literally hundreds
>f letters from students or packets of students' art work along `
-rith their letters. The letters are particularly revealing to me
in that they indicate their perceptions, interests, and
understanding.
Even though I feel well prepared and organized when presenting a
lesson, I have found there is always room for spontaneity and
adapting to unique differences in classes. I think this
philosophy is important because a fresh approach will always help
prevent one from giving a stale presentation.
SETTING UP THE PRQGRA_IM
Most of my organizational methods were learned by trial and
error. Due to constant changes occurring in some schools, I feel
the following approach is the best way. You will also find each
school is unique in itself.
Normally, I meet with one of the principals (depending which one
decides to be in charge). I then discuss the basics of our whole
water conservation program. At this time I also arrange to meet
with all the teachers at the next Principal -Teacher meeting. At
this meeting I explain what I do in the classroom and briefly
outline the objectives of our educational program. This meeting
also gives them a chance to ask questions.
Initially I introduce my calendar. It is enlarged so that each
teacher can sign up for a class by indicating their name, grade
level, time and room number in the chosen open date block. This
calendar is then posted in the teachers lounge room for continued
scheduling in advance.
It is best to have the teachers sign up at the meeting when the
calendar is being passed around during the time I am talking to
them --about 10 or 15 minutes. It also insures their
understanding of the sign up procedure.
Periodically, I check all calendars which have been posted even
if there have been no classes in the school. New sign-ups are
logged. in my master calendar appointment book. At this time I
leave a City Action Slip notice in the teacher's mailbox
confirming the requested class. My business card is attached to
the calendars so that the teachers can phone me in case of
cancellation or changing schedule.
When checking calendars it is beneficial if you can arrange to do
so during a time when several teachers are in the lounge room.
Invariably, teachers tend to sign up when they see me in the
lounge room or somewhere on the campus. Calendars are checked
''C)Owb.11 Page 3
when I give a demonstration at that particular school, but it is
important to check each school -at least once a week.
EXTRACURRICULAR ACTIVITIES
In order to enhance, expand and further support the educational
aspects other innovations come into play such as:
1. Evening classes for Boy Scout/Girl Scout troops.
2. Speaking to the Rotary, Kiwanis, Business Mens'
Club and r�,TT employees, etc.
3. The city co-sponsored a water conservation
workshop held at UOP in Stockton. Eighty eight
teachers attended this workshop.
4. newspaper stories.
5. As a Docent, I have conducted tours in the
Wilderness Area surrounding Lodi Lake. Class
discussion is held at the outdoor amphitheater.
6. Posters: I send letters to all teachers who have
participated in a classroom demonstration with an
invitation to submit a class poster. The poster,
28" X 44", is provided by the city. The
California Department of Water Resources has
declared the month of May as Water Awareness Month
and we have been able to cooperate with their
efforts in this way. This year I picked up 46
posters from classrooms which were distributed to
banks, hospitals, City Hall, restaurants, and
other business establishments. Teachers were
informed of the location of their class poster so
that parents and students might see the exhibit.
All participating officials receiving the poster
were very receptive to the idea.
7. Fair Booth: The most beneficial factor with
having a Fair Booth at our local festival is for
drawing the attention of teachers who'may sign up
for a class. They need only designate the month
they want a class. I call them later for
confirmation of specific day and time.
We are all very interested in anyone planning a similar water.
conservation program and the City of Lodi will assist in any way
possible to initiate and establish this vital program that should
no longer be ignored.

Evaluation of Proposed CYSA Regional Soccer Complex Impact on
WSWPCF Effluent Disposal Land Requirements
Introduction
This memorandum summarizes a preliminary technical evaluation of the adequacy of the city's
WSWPCF effluent disposal lands to accommodate the proposed regional headquarters complex of
the California Youth Soccer Association (CYSA).
The evaluation is based on the recent proposal by the CYSA to locate a major headquarters/soccer
complex on 275 acres of city -owned land east of the I-5 freeway. The 275 acres are currently
scheduled to be added to the land already being irrigated with reclaimed water from the WSWPCF.
Existing Facilities
The city currently owns approximately 1,040 acres of land at its WSWPCF site. Of the total land
available, usage is broken down into the following categories:
Land Use Acres
Treatment plant structures, grounds and unusable land 57 acres
Treatment and storage ponds 45 acres
Lands scheduled to be brought under irrigation 275 acres
Lands for mosquito district fish ponds 12 acres
Lands used by No. Calif. Power Agency (NCPA) 10 acres
power plant
Remaining lands currently under crop irrigation 641 acres
Total 1,040 acres
Of the total land owned by the city, approximately 916 acres are available for irrigation of
agricultural crops or turf and any required additional storage ponds or auxiliary facilities. Another
45 acres are currently dedicated to the storage of off-season industrial waste influent and municipal
secondary effluent.
Proposed CYSA Soccer Complex
The proposed soccer complex will occupy approximately 275 acres of city -owned land which is
currently planned for use to irrigate agricultural crops using municipal secondary effluent,
LOD294 Page 1
industrial wastewater and digested sludge. The soccer complex will consist of a headquarters
office building, a dormitory, parking, three developed park areas, irrigation water storage ponds,
miscellaneous landscaped areas, and up to 50 soccer fields and auxiliary facilities arranged in
modules of 18, 18 and 14 fields each. The initial phase of the project will include the office,
dormitory and two modules of 18 soccer fields each and auxiliary facilities.
Evaluation
A preliminary evaluation of the CYSA proposal was made using a water mass balance model of the
city's effluent irrigation facilities. The model uses a modification of the method recommended in
the California State Water Resources Control Board publication entitled "Irrigation with Reclaimed
Municipal Wastewater. A Guidance Manual", July 1984. In this method, the recommended
irrigation rates are matched with the actual water needs (evapo-transpiration rates) of the various
crops (or other vegetation) being irrigated.
Description of Mass Balance Modal.
The model works by tracking all of the water inflows, outflows and crop water needs on a weekly
basis for one year and calculating the amount of irrigation land needed for each of the crops and
turf, as well as the net change in the amount of storage needed to confine the water on the site.
Inflows to the model include -- municipal secondary effluent, industrial waste influent and
anaerobically digested municipal sludge. Also included is precipitation at average and 100 -year
conditions.
Model outflows include -- crop irrigation, sludge disposal, soccer turf and park irrigation, NCPA
cooling water, mosquito district ponds, and evaporation and seepage from the storage ponds.
Figure 1 shows a schematic of the water mass balance including all of its sources and destinations.
Note in Figure 1 that water for the soccer fields and park land is taken directly from the WSWPCF
secondary effluent and does not pass through the storage basins before it is given tertiary treatment
to satisfy Title 22 requirements for unrestricted irrigation. The soccer facility is currently expected
to include 10 acres of its own storage for the Title 22 irrigation water.
The mass balance model includes the following major components -- irrigated areas by crop type or
turf and storage ponds for reclaimed municipal and industrial wastes.
Key Assumptions. Several important assumptions have been included in the model runs. These
key assumptions are summarized as follows:
• The current mode of operation of the WSWPCF and effluent irrigation will remain essentially
unchanged. The periods for discharge to Dredger Cut and for crop irrigation will remain the
same. The only time period that will be different will be for soccer turf and park irrigation,
which will be longer than the irrigation duration for the other crops by approximately 12
weeks.
WSWPCF flows will be:
- municipal effluent - 5.8 mgd (current) and 8.5 mgd (design).
- the municipal effluent will increase at an annual compounded rate of 2%. This results in
WSWPCF reaching its design capacity of 8.5 mgd in approximately 20 years.
- industrial wastes - 230 mg/yr (no increase in future flows)

• Number of soccer fields - 18 (initial), 36 (by end of first year), and 50 (by end of fifth year).
Soccer turf and park irrigation rates will be at the same weekly rate as pasture irrigation except
at the beginning and end of the natural growing season. At the beginning and end of the
natural growing season, the soccer turf only will be watered at a minimum of 1 inch per week.
One inch per week at each end of the irrigation season is somewhat higher than the normal
demand for pasture, and will be used to stimulate turf growth early in the spring and to help
maintain it well into the fall. The duration of soccer turf irrigation is assumed to extend from
March 1 to November 30 and the total annual irrigation rate will be 66 inches/year (compared to
50 inches/year for pasture land).
• Water for soccer turf and park irrigation will be taken directly from the secondary effluent and
treated to tertiary (Title 22) levels as required for unrestricted landscape irrigation. It will not
pass through the city's existing storage ponds and will be diverted as necessary even after the
discharge of secondary effluent to Dredger Cut is resumed.
• The NCPA power plant is designed to operate for 300 days per year (1 turbine, 10 years). It
will take 1.6 mad and return 0.5 mad of secondary effluent. This will result in 330 mg/yr of
secondary effluent being removed and not available for irrigation or disposal.
• Mosquito abatement district will use reclaimed water to feed several ponds on a 12 acre site
which will be subject to losses by evaporation and seepage, and inflows from precipitation and
secondary effluent as needed. This usage amounts to 40 mg/yr.
• Both 100 -year and average year rainfall conditions are evaluated because each of these
hydrologic condition results in different irrigation land and storage pond requirements for the
project_ The use of 100 -yr precipitation is a conservative assumption used for this preliminary
evaluation to establish the basic feasibility of the project. It is possible that a 10 -yr or 20 -yr
rainfall return period may be acceptable to the Regional Water Quality Control Board
(RWQCB). However, final design requirements for the project will have to be confirmed
before the final project sizing can be established.
Results
The results of the preliminary mass balance model runs are summarized in the attached Figure 2.
In this figure, the amount of land required to dispose of the current and design municipal
secondary effluent, industrial wastewater and digested sludge flows is shown for several key
combinations of crop and turf areas. The combinations of crop and turf areas were selected to
fulfill the requirements of the soccer facility, sludge disposal, and discharge duration to Dredger
Cut. These crop and turf combinations are shown in Figure 2 with the soccer complex at the initial
and final stages of development and with all the facilities operating at the WS1VVPCF design flow of
8.5 mod.
Initial Phase
With 36 soccer fields included in the first year of the CYSA project, the total required acreage
ranges from 719 to 745 acres, depending on the "design" precipitation rate. The larger acreage
assumes that the facilities will be subject to an extremely wet year of 30.5 inches annual rainfall
(i.e. the 100 -year rainfall return period for Lodi). The smaller acreage represents the land
requirements for an average precipitation year with 18.0 inches of annual rainfall. The city's
current storage capacity of 45 acres would be adequate for the 29 to 35 acres estimated by the
model at this initial stage. These acreages are for the city's storage requirements only and do D

include the CYSA's 10 acre irrigation storage pond for the soccer complex and the 12 acres for
mosquito fish ponds. The 10 -acre irrigation
storage pond for the soccer complex will need to
provide a minimum of 6.0 million gallons of active, working storage.
Table 1 is a summary of the annual water uses and actual land requirements for the initial phase.
Note that Table 1 includes the largest values for irrigation land and storage pond land from the
average and 100 -year rainfall model runs. For example, the irrigation land area required for the
"wet" year is larger than for an average year because the additional precipitation must be used for
irrigation. Conversely, the model predicts that slightly more pond area will be required during an
average year than a wet year. Therefore, this larger combination of crop land and storage ponds
produces the total acreages that needs to be provided.
In 5 years, when the final 14 soccer fields are placed in service together with a small increase in the
NVSiVPCF average daily flow, the total required acreage increases to between 788 and 823 acres,
depending on the annual precipitation (See Figure 2). A total of 37 to 49 acres of storage ponds
would be required, therefore, the current 45 acres of storage ponds may still be adequate for these
conditions. Table 2 presents a summary of annual water uses and land area needs in the second
phase. As before, Table 2 includes the larger of the pond and acreage values from each of the two
rainfall scenarios.
Final Phase - Design Flows.
When a1150 soccer fields are constructed and the WSNVPCF is operating at full design capacity, the
total land area required would exceed 1,030 acres during a 100 -year precipitation year. Since the

amount of land currently available is 973 acres, the city may have to purchase an additional 57
acres to handle the "wet -year" precipitation at design conditions.
As an alternative, the existing land could be irrigated at somewhat higher rates than assumed in the
water mass balance model runs. For all of the model runs, an irrigation efficiency of 80% was
used in calculating the amount of water which has to be applied to satisfy the evapo-transpiration
requirements of the crops. When irrigating crops, however, it is necessary to apply a certain
amount of "excess" water to control the salt concentration (salinity) in the root zone of the plants.
Irrigation efficiencies generally range between 50-80%, depending on the irrigation water quality,
soil characteristics and the salt tolerance of the crops. In general, soils with fine grain sizes and
clays require more leaching water than larger grained soils. In this case, all of the effluent could be
utilized on the existing land if the irrigation efficiency were reduced to 77% in an average year and
to 68% in an extremely wet year. A summary of the land requirements and annual water uses at
design conditions is presented in Table 3, assuming the reduced irrigation efficiency of 68% from
above.
The importance of controlling irrigation efficiency cannot be overestimated If insufficient
irrigation water is used, especially in fine grained soils or with salt sensitive plants, crop yields will
drop significantly as the salt concentration increases in the root zone. Perhaps evenmore
important, if the irrigation efficiency is too low and excessive water is used on the crops, the extra
water can lead to degradation of the underlying groundwater resources. In addition, over -irrigation
could lead to water shortages and user cutbacks during drought years in the future.
Title 22 Effluent Treatment.
All reclaimed water used to irrigate the soccer field turf, park and landscape areas for the proposed
CYSA complex must meet the requirements of Title 22, Environmental Health, of the California
Code of Regulations, as administered by the California Department of Health Services. These
regulations require that the reclaimed water must be coagulated, filtered and disinfected to very

high standards before being used for unrestricted landscape irrigation. This additional treatment
would have to be provided prior to completion of the initial phase of the soccer complex.
Based on the projected water demand for turf and park irrigation during the maximum week, the
design capacity of the initial phase Title 22 treatment facilities will be approximately 1,300 gpm.
This design capacity assumes that the required volume of filtered water is produced on a
continuous 24-hour basis. The initial filtration, disinfection and pumping facilities would be
designed to be expanded to approximately 1,750 gpm before the city needs to serve the full
complex of 50 soccer fields. The ultimate pipeline would be constructed in the initial phase.
Preliminary construction cost estimates for the Title 22 coagulation, filtration and disinfection
facilities for the initial soccer complex (36 fields) and park facility are summarized in Table 4.
These budget estimates include construction costs (equipment and installation) and engineering
costs for the Title 22 treatment and disinfection facilities and a new pumping station and piping to
transport the reclaimed water to the pond at the soccer complex . They do not include any costs for
odor control facilities, environmental documentation or annual operation and maintenance costs.
The city staff has estimated that providing odor control at the headworks and primary clarifiers
would cost $800,000 and an odor masking system for CYSA special events would cost
approximately $100,000.
Annual operation and maintenance costs for the Title 22 treatment and disinfection facilities and
pumping station are estimated to be approximately $150,000/year for the initial year of operation
(in 1994 dollars). Operation and maintenance costs for the odor control and masking systems are
not included in the above estimate.
3 The crop irrigation efficiency is 77% during an average precipitation year and 63% during a 100 -year
precipitation year.

Conclusions
The following conclusions have been drawn from this preliminary evaluation:
• There is currently sufficient water, storage and land acreage for the initial phase of the CYSA
soccer facility to be implemented -- 36 soccer fields with auxiliary facilities, office and
dormitory buildings, and park and landscaped areas.
• There will be sufficient water and land acreage for the second phase of the CYSA soccer
facility to be implemented in 5 years. However, the estimated requirement of 49 acres of
storage ponds exceeds the existing 45 acres of ponds. Depending on a more detailed analysis
of the existing ponds, 45 acres may be adequate for the first few years of the second phase of
development, but additional storage would be required soon thereafter.
• Substantial new storage pond capacity will be needed to properly manage the recycled water as
the WSWPCF reaches its design capacity of 8.5 mad. At that time, approximately 81 acres of
storage ponds will be required, or 36 acres more than currently exist. The modeling runs
indicate that the ultimate storage pond requirements for the WSWPCF operations are not
increased by the presence of the CYSA soccer complex.
• At the design capacity of 8.5 mgd and average precipitation, it will be necessary to reduce the
crop irrigation efficiency slightly to 77% to use all of the reclaimed water on the currently
available property at WSINVPCF. For a wet year (100 -year precipitation), the irrigation
efficiency will have to be reduced to approximately 68%. Both of these efficiencies are well
within expected values for the irrigation water quality, soil characteristics and crop and turf mix
at the WS`N'PCF site.

PRINCIPLES FOR FURTHER NEGOTIATION RELATIVE
TO A CONJUNCTIVE USE PROJECT
(10/16/95)
1. The following principles shall apply to a phased conjunctive
use/water banking project (Project) to be undertaken' jointly by
the Eastern San Joaquin Parties (ESJP) and the East Bay Municipal
Utility District (EBMUD).
2. Eastern San Joaquin County is an area suffering from an
overdrafted groundwater basin and includes, among other areas,
the territory within the boundaries of the Eastern San Joaquin
Parties, that is, the Woodbridge Irrigation District, the North
San Joaquin Water Conservation District, the City of Lodi, the
Stockton East Water Conservation District, the City of Stockton,
the Central San Joaquin Water Conservation District, and the
adjoining County territory under the jurisdiction of the San
Joaquin County Flood Control and water Conservation District.
3. The ESJP will undertake joint negotiations with EBMUD and
other interested parties including Sacramento County, if
requested, but two way negotiations with EBMUD on matters of
concern to .the ESJP and EBMUD shall continue.
4. The priorities of the Project shall be in order, as follows:
FIRST: To stop the overdraft of the Eastern San Joaquin
County basin;
43614-1
77045122588110-17-95/1
SECOND: To restore the basin to an agreed upon
progressively improving recovery level;
THIRD: To supply the water needs of the ESJP;
FOURTH: To supply the water shortage needs of EBMUD in dry
years.
5. Project Conveyance Facility
5A. The ESJP continue to prefer a canal along the original
alignment of the Folsom South Canal to allow water to move in
both directions as needed.
5B. If EBMUD and the ESJP elect to construct a conveyance
facility from the Folsom South Canal to the Aqueducts the
facility should have the capacity to convey EBMUD's full
entitlement of 150,000 acre-feet per year and the facility should
have appropriate turnouts north and south of the Mokelumne River
accessible to the NSJwCD and other interested water users in a
manner which will provide gravity service as originally
contemplated from the alignment of the Folsom South Canal.
5C. Even if EBMUD and the ESJP construct a facility from
the Folsom South Canal to the Aqueducts, a conveyance facility
should be constructed north from Peters to an agreed upon point
north of the Mokelumne River.
43614-1
2 77045/22588/10-17-95/1
6. Water Supply
6A. The minimum, acceptable supply of water to ESJP in wet
years (as defined by DWR) is 300,000 acre-feet.
6B. 371,000 acre-feet of water should normally be available
in wet years through the EBMUD entitlement from the American
River, or an equivalent amount from the EBMUD Mokelumne River
entitlement; the SEWD-CSJWCD entitlement from the Stanislaus
River; all water on the Mokelumne River not now used by EBMUD or
any downstream water right holders; any unregulated flows on the
Calaveras River which can be put to use; and, any unregulated
flows in Little Johns Creek which can be put to use.
7. Facilities which shall provide water shall include but will
not be limited to:
7A. A conveyance facility extending at least to an agreed
point north of the Mokelumne River and as far south as Peters.
7B. Gravity diversion structures from the Mokelumne and.the
Calaveras to the north -south conveyance facility.
7C. A combination of new agricultural distribution systems
such as injection wells, surface water facilities, and in -lieu
recharge systems with a minimum,,total capacity of 265,000 acre-
feet with a minimum of 10,000 acre-feet of annual, firm surface
43614-1
3 77045/22588/10-17-95/1
water delivered to NSJWCD.
7D. EBMUD injection/extraction or in -lieu facilities with a
minimum capacity of 70,000 acre-feet, which will operate within
geologic formations in a manner which will in no way impair water
quality within Eastern San Joaquin County and will create a
common source of water for the ESJP and EBMUD.
B. Phase I Extraction Thresholds; Goals; Use:
8A. The Parties shall develop a dynamic base groundwater
profile through groundwater and saline intrusion monitoring
facilities as a means to set minimum, standard groundwater
conditions for the area and to continuously monitor the basin.
The profile will include information on water quality, salinity
levels, and water table elevations.
8B. EBMUD shall not extract water for export if the
groundwater levels in the basin drop below the groundwater levels '-
reported for the fall of 1990 by the San Joaquin County Flood_
Control and Water Conservation District.
8C. The groundwater elevation goals are to be 30 feet below
sea level east of Highway 99 and 20 feet below sea level west of
Highway 99 and where groundwater elevations are now above those
levels, then the current elevations. These groundwater elevation
43614-1
4 77045/22588/10-17-95/1
goals shall be revised if warranted through analysis of the
information obtained pursuant to the monitoring described in 8A
in conjunction with other relevant data, water quality goals,
groundwater levels, and salinity 'intrusion goals.
8D. Should the goals set forth in 8C not be met within ten
years after the start of project operations, Phase II shall be
implemented.
8E. Until the goals of 8C are met, EBMUD shall be allowed
to extract an agreed upon percentage of the water stored by EBMUD
within the groundwater basin. After the goals of 8C are met, the
Parties shall be entitled to an equitable share of all waters
stored in the basin as part of this project as agreed upon by the
parties. All extractions by EBMUD shall remain subject to 8B.
9. Phase II shall be implemented if the goals set forth in 8C
are not achieved within ten years of the Project's start of
operations. The Agreement between the parties shall ensure that
Phase II will be implemented by the parties when required.
10. Phase II may consist of one or more of the following:
10A. An enlarged and reconstructed Farmington Dam suitable
for water storage as well as flood control.
10B. South Gulch Water Conservation Reservoir.
43614-1
5 77045/22588/10-17-95/1
10C. Additional recharge facilities.
10D. Other facilities as may be agreed upon by the parties.
11. Use of Delta and/or Sacramento River water, if any, shall be
proportionate between EBMUD and the ESJP.
12. Localized groundwater drawdown, caused by the Project, shall
be minimized so as to avoid unnecessary impacts on groundwater
users through prudent extraction site selection. Adverse impacts
on groundwater users shall be fully mitigated. Seepage and high
groundwater level impacts caused by the Project shall also be
fully mitigated.
13. The ESJP continue to be opposed to the EBMUD approach set
forth in Composite No. 2 of the Water Supply Management Program.
14. Integration of EBMUD's American River supply into the
project is essential to develop a successful conjunctive
use/water banking program between EBMUD and the ESJP. It is
recognized that diversions from the American River by a•joint
American River project would be subject to the "Judge Hodge
Decision," as it may be modified. EBMUD in consultation with the
ESJP, shall, seek modification of the terms of the "Judge Hodge
Decision", to allow for conjunctive use of both American and
hIokelumne River waters. Integration of San Joaquin County's
43614-1
6 77045/22588/10-iT-95/1
filing on -the American and Mokelumne Rivers and other local water
entitlements` as well as increased yields from combined
operations, new facilities and supplies, should be evaluated for
use in any conjunctive use project. Other reasonable alternatives
should be considered in a study to provide information on yield,
costs and constraints.
15. The cost of distributing water to the various parcels of
agricultural lands within the territory of the ESJP will vary
substantially depending upon the proximity to the sources of
water and the extent of surface water distribution facilities
already in place as well as such additional facilities as may be
required in the Project. The inclusion of EBMUD's needs will
require distribution of water to additional agricultural lands
beyond those necessary to meet the needs of the ESJP. EBMUD's
participation in the basin must not directly or indirectly impair
providing for, or increase the cost of, meeting the water needs
of the ESJP.
16. The conjunctive use study and joint plans for the Project
shall not use land fallowing or other irrigation curtailment .
except reasonable conservation to develop water supply:
17. -Costs shall be allocated in an equitable manner.
18. It is understood that the -project may require further review
under the California Environmental Quality Act (CEQA), If CEQA
43614-1
7 77045/22588/10-17-95/1
review iG.found.to be necessary for the project it will.be
pursued jointly.
19. If a favorable court ruling,'allowing the use of EBMUD
American River Contract water in a conjunctive use project
utilizing American River and Mokelumne River water and the
Eastern San Joaquin County groundwater basin, is not received
within a mutually agreeable time of an agreement for conjunctive
use between EBMUD and the ESJP, and if an alternate supply is not
identified, then the agreement shall terminate.
20. These Principles are established under the assumption the
groundwater basin will have sufficient capacity to store the
amount of water needed by the ESJP and EBMUD.
21. Governance/Finance
21A. The current Policy and Technical Committees of•the ESJP
will recommend creation of an appropriate organization for the
purposes of governance and finance of the ESJP share of the
Pro ect•.
21B. In selecting the type of agency or organization to be
created, the ESJP will enter into discussions on form weighing
the factors of ease of implementation, taxing/assessment
authority, degree of administrative efficiency upon formation,
and boundary issues in making their decision.
43614-1
8 77045/22588/10-17-95/1
21C. The governing board of the proposed agency will be
comprised of members appointed by the East San Joaquin member
parties. Each member party will appoint at least one
representative to the governing board. Additional representation
will be apportioned through the benefits to, and burdens on, the
respective member parties. Members of the governing board shall
be elected officials of the respective member parties.
22. Until such organization is formed, the present Policy and
Technical Committees of the ESJP will take such actions as
necessary to continue moving forward with the Project.

Water saving tips and.other Water Conservation Program information:
1. Before washing down paved areas for public health or safety (see :4 above) or for any special circumstances call the Water Conservation Office
at 333-6829 for prior approval.
2. For lawns with a run-off problem, apply water for a short period of time and then allow enough time for it to soak in before turning the water back
on, for example: 5 minutes on, 20 minutes off, 5 minutes on. This will increase the amount of water being absorbed and decrease the amount of
water running off into the gutter. Consult landscapers/gardeners/nurseries for improving your lawns water absorbing capacity and for other ideas.
3. During and following rain it is not necessary to water lawns and landscaping, and normally from November 1 through February 28, one watering
per week or less is more than enough.
4. If you need extra watering due to fertilizer application or for new turf/seeding, please first notify the Water Conservation Office at 333-6829.
5. Regularly replace your back-up batteries in your automatic sprinkler controls to prevent excess watering due to power failures or interruptions.

Date: September 13, 1993
City of Lodi's Water Conservation Program Benefits
Summary of a report to City Council dated August 12, 1993
History
The City of Lodi's Water Conservation Ordinance and Program have been in effect since 1977. This
is one of the few conservation programs in the Valley that remained in effect after the 1976-77
drought through the start of the 1986-1992 drought.
School Education Program
The popular Water Science Educational Program was introduced to Lodi elementary schools in 1986.
This program supplements and advances Lodi's total effort to conserve water with science
demonstrations/presentations taught in public and private elementary classrooms with the objective of
teaching water awareness and water conservation techniques.
Effectiveness of Program
The citizens of Lodi, in cooperation with the conservation program, have significantly reduced their
water usage. From 1970 through 1976 the average water use was 359 gallons per person per day
(gpd). The average for 1991 and 1992 was about 230 gpd. (Calculated using total water production
divided by population.)
Groundwater Levels
Lodi's water supply, as with many valley communities, is taken from their groundwater aquifers.
Although this resource is renewable, valley -wide we are taking more water out than is being replaced.
How much has reduced water usage in Lodi slowed the depletion of Lodi's groundwater table? This is
difficult to determine considering the many influences on the groundwater such as river flows, rain,
other municipal pumping, and agricultural pumping, in addition to Lodi's 22 wells. The fact is that the
groundwater table is dropping under Lodi. Lodi's groundwater table dropped over 10 feet from 1983 to
1992. Less water pumping due to Lodi's water conservation efforts have slowed this depletion.
Pumping Savings
Water saved through conservation also saves money. The most direct cost savings is in electrical
costs to -pump the groundwater. The 1992-93 electrical cost of pumping water in Lodi was
approximately $115 per million gallons. Currently when a residence uses more water, there is no
additional income to the City since residences are not metered. (To retrofit residences with meters in
Lodi would cost roughly 315,000,000.) Other cost savings include decreased maintenance, repair,
and replacement costs to wells, pumps, and motors.
To more accurately determine the reduced water usages, Lodi was compared to three area
communities which had only voluntary or inconsistently enforced water conservation regulations, and
also had reliable water use data going back to 1980.
The averages of these three communities were used to determine a "background level" of water use
reductions due to drought publicity and minimal water conservation efforts. It should be kept in mind
that Lodi probably started at a lower water use rate in 1980 than the other three communities due to
Lodi's already existing water conservation efforts.
The reductions in water use for the three area communities were averaged then subtracted from
Lodi's total water savings. This results in a net savings of 3.52 billion gallons since 1980 or 293
million gallons per year.
The electrical cost savings alone for the water saved above are calculated at $404,856, using present
costs. (These electrical savings are conservative considering the lower water usage in Lodi in 1980,
due to the conservation program, were not calculated.) The cost of the entire Water Conservation
Program, adjusted to today's dollars from 1979-80 through 1991-92, totaled only $210,342.
Reduced Number of Wells Needed
The major cost savings however is in the number of wells that are needed to meet the City of Lodi's
water demands. At today's rate each well costs the City of Lodi up to $500,000 to explore, test, drill,
develop, equip, and lay water mains to the distribution system (this does not include treatment costs).
The 1962 water master plan calculated the City needing 29 wells for today's population. The 1976
and 1990 water master plans had Lodi needing approximately 26 wells with a population of 54,000.
Currently the City of Lodi is meeting the water demands in Lodi with a total of 22 wells (18 active and
4 standby).
Therefore, if the City required the 26 wells as projected in the 1976 and 1990 water master plans
there would be four additional wells needed at this time. At today's cost that would be approximately
$2,000,000 (without any treatment). Communities which abandon water conservation efforts have
only delayed theses costly expenditures. Communities with ongoing programs may totally eliminate
these costs if the reduced demands can be continued.
The City of Lodi had been ordered by the State to install treatment systems on City wells for
dibromochloropropane (DBCP). (See the City of Lodi's Annual Water Quality Report for 1992 for more
details). The City installed one treatment system at a cost of approximately $500,000. Construction
of further treatment systems on existing wells is being delayed and possibly avoided by Lodi's ability
to keep current DBCP wells in a "standby" mode due to reduced water usage. So far in 1993, the City
has been able to avoid using any DBCP well. (Note: some future wells may need treatment.)
Wastewater Treatment Savings
Another significant benefit of the citizens of Lodi's water conservation efforts has been the reduction of
wastewater flows. These calculations show savings of nearly $240,000 from 1987 through 1992.
More significant is the effect on treatment plant capacity. Reduced wastewater flows may extend the
life of the most recent $10,000,000 expansion three to six years.
2
SUMMARY
Lodi's ongoing water conservation program has been a benefit financially to the citizens of Lodi. After
subtracting the cost of the program the net saving to water and wastewater operating budgets have
been over $57,000 per year. Additionally, reduced capital expenditures run in the millions of dollars.
The program has also reduced the overdrafting of Lodi's groundwater.
While these efforts have kept your water rates among the lowest in the State, costs have risen every
year and your rates will soon need to be raised. Water conservation efforts will help keep your rates
among the lowest in the State.

A RESOLUTION OF THE LODI CITY COUNCIL
ESTABLISHING A "LOCAL RULE" FOR
WATER MEASUREMENT LAW
(SENATE BILL 229)
WHEREAS, the City of Lodi has the responsibility to comply with Water Measurement Law, Senate Bill
229 (1992); and,
WHEREAS, Senate Bill 229 does not require water meters to be read or billings to be based on metered
rate; and,
WHEREAS, if meters were installed at this time unnecessary wear would shorten the life of those meters;
and,
WHEREAS, the City of Lodi does not have a residential meter users rate at this time; however, it is
anticipated it is possible the City may establish a rate with the City's next water rate increase; and
WHEREAS, the City of Lodi has been collecting fees for meters since January, 1992, as required by Senate
Bill 229. These funds are placed in a dedicated account specifically for purchase and installation of the required
meters.
NOW, THEREFORE, BE IT RESOLVED, that the City of Lodi does hereby establish a "Local Rule",
under which the City of Lodi will continue to collect fees on new water services for water meters and installations,
but make the installations in the future at such time as metered billing is implemented.

COUNCIL COMMUNICATION
AGENDA TITLE: Approve Principles of Negotiation for Conjunctive Use Project by
Eastern San Joaquin Parties and the East Bay Municipal Utility District
MEETING DATE: December 20, 1995
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council approve, by motion action, the principles of
negotiation for the Conjunctive Use Project.
BACKGROUND INFORMATION: Each governing body of the East San Joaquin Parties (ESJP) is
being asked to approve the principles of negotiation for the
Conjunctive Use Project being undertaken jointly by ESJP and
East Bay Municipal Utility District (EBMUD). Attached as Exhibit A
is a letter, dated November 9, 1995, from Andy Christensen of Woodbridge Irrigation District (WID).
Mr. Christensen is the Chair of the ESJP Technical Committee and is asking each agency of ESJP to
review the prior request of Supervisor Barber and approve the principles of negotiation. Supervisor Barber's
request and the principles are attached as Exhibit B. Supervisor Barbers request was sent to the
City Council in October of this year but was not acted on at that time.
The Technical and Policy committees of ESJP have worked hard to develop these principles which will be
used as a guideline in the negotiations with EBMUD. Rather than repeating everything, I have circled
important areas in Supervisor Barber's letter which address some of the concerns Council may have.
John Pulver, the County's Water Resources Coordinator, and Andy Christensen, the Chair of the ESJP
Technical Committee, will be in attendance at the Council Meeting in order to answer any questions on
this item.

On May 2, 1995, the Board of Supervisors, but also with your support and ratification, signed an
study agreement for an initial study effort with EBMUD of an regional conjunctive use ground
water banking project that holds promise to be one of the most dynamic water projects proposed
in recent years with the potential of (1)halting saline intrusion problems, (2)stopping the draft of
ground water, (3)and meeting the present and future water needs of eastern San Joaquin County
(4) while providing for the dry year water needs of EBMUD. Your support of each step in this
process is vital if the effort is to continue. Initial study efforts have shown a range of project
alternatives that conceptually meet project goals. Study efforts can not proceed further until an
agreement is negotiated with East Bay Municipal Utilities District that defines mutually
acceptable project goals and satisfactorily protects ESJP ground water, ground water basin, and
surface water interests.
On October 17, 1995, Supervisor Barber sent a letter to all agencies that make up the
Eastern San Joaquin Parties entity asking that agencies support continued negotiations with East
Bay Municipal Utilities District for a joint project. Your help is needed once again and we ask
that your entity take action to review, consider, and support the request made in Supervisor
Barber's letter. A copy of your indication (resolutions or document) of support should be sent to
Supervisor Barber's office. I have included a copy of the October 17, 1995 Supervisor Barber
letter and "Principles". Thank you for your continued support!
Sincerely,
Anders Christensen, Chair

RECEIVED OCT 1 8 1995
As you know, we have been working for some time on a possible joint conjunctive use project
with the East Bay Municipal Utility District (EBMUD). A study has been undertaken jointly
with EBMUD at a cost of over $600,000 with over $300,000 provided through the Board of
Supervisors by way of a San Joaquin County Flood Control and Water Conservation District
assessment and the other half provided by EBMUD. That study has been completed. Our work
has been done in connection with a Technical Committee and a Policy Committee to which you
have appointed representatives.
Since the study is now complete, it is time to move forward with substantive negotiations with
EBMUD and perhaps other interested parties. The Policy Committee has asked that I write to
you and ask that you endorse continued negotiations under the proposed Principles. The
enclosed Principles are intended as guidelines under which the East San Joaquin Parties ("ESJP")
will undertake nep-otiations.
We believe the project contemplated by the Principles would assist in meeting the water needs of
the ESJP and EBMUD, and would particularly address the needs of our critically overdrafted
groundwater basin.
The conjunctive use Policy Committee has worked very hard to assemble a set of Principles _
acceptable to all of the ESJP representatives. These Principles are by no means the final word on
how a future project would look. Rather, they are a set of guidelines to steer the ESJP during the
negotiation process with EBMUD. Any final agreement will be subject to approval by the

Annual Water Quality Report for 1994
To keep our water customers informed about the drinking water
in Lodi, the City of Lodi distributes this annual report. The Water
Quality Report on Page 4 summarizes testing performed on
Lodi's water supply by State certified laboratories. To better
understand the report please note the description of terms and
abbreviations at the top of Page 4.
The City of Lodi supplies high-quality groundwater through
approximately 24 City wells. These wells operate automatically on
water pressure demand so that when water use increases, more
wells come on line.
All 24 City wells are interconnected through approximately 198
miles of water mains. In 1994 4.660 billion gallons of water were
pumped to satisfy Lodi's water demands. This represents 5.2%
less than 1986 in spite of a population growth of 25% since 1986.
Your continuing water conservation practices have really paid off!
A 1993 report calculated savings to be far above the cost of the
Water Conservation Program. Maintaining your water
conservation efforts results in annual cost savings in operation
and maintenance and averts millions of dollars in capital
expenditures, helping water rate increases stay low as possible
and conserving a valuable natural resource. Please read the
water conservation message on Page 3.
Drinking water provided in Lodi is of high quality and not only
DBCP
The California Department of Health Services (DHS) sets drinking
water standards, and has set a limit for Dibromochloropropane
(DBCP). This organic chemical was once a popular pesticide used
in and around Lodi by area farmers until banned by the government
in 1977. DBCP has been shown to increase cancer nodules in rats
and mice when exposed to very high levels over their lifetimes. It is
a theory that these chemicals may also increase the risk of cancer in
humans who are exposed over long periods to very minute amounts.
Although even the possibility of this theory being correct is debated
by leading scientists, the United States Environmental Protection
Agency (EPA) and DHS have set the drinking water standard for
DBCP at 0.0002 parts per million (ppm) or 0.2 parts per billion (ppb)
to reduce the theoretical risk of cancer. The theoretical risk of cancel
is based on lifetime (70 years) exposure and drinking about twc
quarts of water every day.
meets but is better than all State and Federal drinking water
standards (listed on Page 4). Certain wells would individually
exceed the Dibromochloropropane (DBCP) standard if used.
Please see the "DBCP Update" below for more information. Also,
one well is slightly above the State limit for Trichloroethylene
(TCE). This well is not being used.
Lodi takes 18 samples weekly from throughout Lodi's water
distribution system for bacterial water quality. Regulations allow
for 5% of all total coliform samples in a month to be positive. In
November 1995 Lodi had 6% positive and exceeded the standard
for "total coliforms". While State health officials agreed there was
no health threat from this bacteria, Lodi officials decided to
chlorinate Lodi's drinking water system for five days in December
1994 to cut down on these harmless bacteria that show up in the
testing procedure. Occasionally the City may have to chlorinate
your water, but we will make every effort to inform you in local
papers before the drinking water is to be chlorinated.
While your water rates have been kept as low as possible, water
rates have recently been raised to help meet funding needs_
Please read the important message on your water rates on Page
2 of this report.
If you have any questions about this report or the quality of
Lodi's water, please call the City's WaterlWastewater Office
at 333-6740.
UPDATE **************************************
Activated Carbon (GAC) treatment system in use has cost the City
approximately $600,000.
VVater which meets this standard is considered safe with respect to
drinking water with this level of DBCP_ The limit of 0.0002 ppm
equals one drop in 66,000 gallons of water (it would take over 350
years to drink 66,000 gallons of water at 2 quarts/day). Theoretical
risks associated with DBCP are based on 70 years exposure, so
even EPA states that these levels in Lodi's water would not be
significant when exposed for a relatively short time.
14 City wells at some point exceeded the new limit for DBCP. Of
these 14 wells, the City has abandoned 4 wells, levels in 5 wells
came back into compliance, 1 well has a treatment system, and 4
wells remain out of compliance (standby). The one Granular
The 4 wells over the DBCP limit could be used for relatively short
periods of time only during peak water demand hours in the hottest
parts of the year, yet they are regulated as if they were on 24 hours
a day, 365 days per year. With that in mind, the City proposed an
alternative treatmentfoperation system that would save our citizens
millions of dollars, yet meet Federal regulations. However, it is
apparent that at this time DHS and EPA officials are not going to
allow Lodi's proposal.
Capacity of the City's water system has not kept pace with peak
water demands while the City has been trying to resolve the
DBCP issue. Therefore, to help meet the peak water demands
expected this summer, the City Council has approved the
installation of three more GAC treatment systems at a cost of
approximately one million dollars. Two systems are scheduled
for completion this summer and the third site, scheduled for
completion before the 1996 peak water season, will also have a
1 million gallon storage tank located east of Highway 99.
The City has also brought a lawsuit against the manufacturers of
DBCP. This lawsuit will attempt to recover some of Lodi's costs
including replacing and treating DBCP contaminated wells.
In the meantime you may consider your water safe to drink. The
City will keep you regularly informed of progress made to resolve
this issue. If you have any questions regarding this update, please
call the City of Lodi's Water/Wastewater Office at (209) 333-6740.
City of Lodi, Annua! V, a'er Qua'ity Report to Customers, June 1995. Pa; e t
Qr About a Recent Water Rate Inci -►se �
After a Public Hearing on April 19, 1995 the City Council raised
water rates to help meet increasing financial needs of the City's
Drinking Water System. The new water rates were approved
after much debate and several meetings at which the Public
Works Department detailed funding deficiencies for the water
system. This is the first of a series of needed water rate
increases.
The City operates and maintains your water system which
includes: 24 wells, 198 miles of distribution mains, an elevated
water tank, chlorination systems, emergency generators,
equipment for installing and repairing water lines, a laboratory
for water quality analyses, and a granular activated carbon
treatment system on one well. There are also ever mounting
costs to meet State and Federal regulations include increased
costs for engineering, monitoring, administration, treatment,
regulatory fees, etc. City policy also directed that 20% of the
Water Utility revenue go to the City's General Fund to help pay
for items such as Police and Fire Services, Parks and
Recreation, Hutchins Street Square, etc.
There are MAJOR deficiencies in our water system we must
face. For example, many distribution mains are 70+ years old.
These undersized and failing water mains, located chiefly in the
eastside and downtown areas, should be systematically
replaced. If water main life spans were considered to be 70
years, we should be spending about $836,000 annually to keep
up. The sad fact is, however, over the past few years we have
spend less than $150,000 per year in water main replacements.
Costs associated with the DBCP regulations are also a major
impact. The City has worked hard to keep these costs at a
minimum while at the same time deliver water which meets strict
State and Federal standards. Also, the City has financed the
installation of DBCP treatment equipment with a low interest
(3.41%) State loan. For more information please read the
"DBCP Update" found on Page 1 of this report.
Public Works reports to the City Council have focused on water
system deficiencies requiring the most attention. Funding needs

'The percent increase was above the rates at that
time.
After the April 19, 1995 Public Hearing, City Council raised the
water rates as listed below effective June 1, 1995. This raise
starts funding a water main replacement program and repays
loans used for DBCP cleanup efforts. The old water rate
structure was also modified to adjust discrepancies between flat
rate and metered customers. Rates for flat rate customers were
raised 17.7%. Metered customer's base rates were raised only
8%, however the amount of water formerly included in the base
rate was deleted. Charges for the metered water was therefore
raised only 4%. If your water meter is larger than needed for
your peak water uses, the City may be able to install a smaller
meter to reduce your monthly base rate. City Council actions
also lowered the water utilities contribution to the General Fund
to 17.7% (from 20%).
This is only the third water rate increase since 1976, but more
increases will be needed to keep pace with the ever mounting
costs due to regulations, inflation and other water system
needs. Lodi s water rate structure will again be reviewed for
possible changes in the relationship between flat rate and
metered customer charges, and for possible changes to
encourage water conservation.
If you have any questions concerning these water rates or
your meter size please call the City of Lodi Water
!Wastewater Office at 333-6740.

in our recent past. Since 1962 Lodi has lost a total of 16 feet of
groundwater table based on City well readings. The six-year
drought period, 1987 through 1992, accounted for 12 feet of this
decline? ,
Since 1992 we have had two very wet winters and one below
normal. We have seen our groundwater regain approximately
one foot. It is nearly impossible to determine how much water
conservation efforts have helped, but the more we conserve, the
longer we can rely on this quality drinking water source and avoid
expensive surface water treatment.
Peak Water Demand Crisis in Lodi
The City is facing a possible shortage of well capacity this
coming summer. Due to delays caused by the City's ongoing
dilemma with DBCP contaminated wells, well construction and
treatment have not kept pace with increasing population. Thus,
the need for wafer conservation during peak -water -use
hours will be most critical this year.
The peak water demands for the City of Lodi s water system
occur twice daily, between 6 & 9 a.m. and again between 7 &
10 p.m. The highest peak water demands occur during the
months of June, July, August, and September (with July and
August typically the most crucial).
These peak water demands determine the total number of wells
the City of Lodi s water system must have. (The City's water
tower is used mainly for regulating water pressure. During peak
How Can You Help?
Some water uses during peak hours can be shifted to non -peak
hours, such as:
• Automatic timers for lawnllandscaping watering
could be set to operate ending before 6 a.m., or
starting after 10 p.m.
• Perhaps the laundry could be put off until after 9
a.m. or done before 7 p.m.
• Could water uses such as the daily shower, car
washing, dishwashing, etc., be changed to non -peak
hours?
• Some commerciallindustrial water uses could be
changed to non -peak hours.
There are probably other good ideas you can come up with. As
a bonus, making simple changes in water use patterns can save
you $$$.
It costs up to one-half million dollars ($500,000) to site, drill,
develop, equip, and connect a new well to the drinking water
system. If we can keep down our peak water demands in Lodi,
costs of some future wells can be avoided.
Please see the summary of regulations below and if you have
any questions on water conservation or for further information on
reducing peak demands, please call the Water Conservation
Office at 333-6829.
Thank you for past and continued cooperation.

SECTION VI
RECYCLED WATER OPPORTUNITIES
WASTEWATER TREATMENT FACILITY
The City -owned and operated wastewater treatment facility is located approximately six miles from the
City of Lodi's water service area. The treatment facility is a conventional activated sludge process with
anaerobic digestion and chlorination/dechlorination. Currently a daily average of 6.2 million gallons of
domestic wastewater is treated at the treatment facility. Additionally the City operates a separate
industrial system which utilizes a cost-effective ponding and direct irrigation process. The industrial
system has a separate trunk line from the City to the treatment facility which is primarily used for
cannery process water discharges of approximately 230 million gallons annually.
RECLAMATION / RECYCLING
Presently there are no plans to construct six miles of pipeline and pumping stations necessary to return
reclaimed/recycled water to the water utility service area. Treated wastewater is either reclaimed/
recycled (mainly for irrigation of City -owned farm lands leased out to local farmers) or is discharged to
the San Joaquin Delta.
The City owns a total of 1,040 acres of land at the treatment facility. Currently 641 acres are irrigated
with reclaimed/recycled water from the domestic treatment process and/or with process water from a
cannery located within the City of Lodi. There are other ongoing and pending projects to further utilize
reclaimed water in the area of the City wastewater treatment facility. Reclaimed/recycled water from
the domestic treatment process effluent is used on-site at a 49 megawatt steam power generation facility
and fish rearing ponds for the mosquito abatement district. A pending future project will utilize another
275 acres of land at the treatment facility for irrigation of a youth soccer complex. Exhibit Q is a recent
study which shows current and pending water reclamation/recycling projects and usages.

SECTION VII
OTHER REQUIREMENTS OF THE PLAN 11yIISCELLANEOUS
MECHANISM FOR DETERMINING ACTUAL REDUCTIONS
Actual reductions can be determined by total water production records, peak water usage records, and
individual commercial and industrial water meter usage records.
SUPPLY DEFICIENCIES
Historically, there have been no water supply deficiencies nor are there any expected in the immediate
future_ Drought conditions have a longi term impact on groundwater levels as discussed earlier, but
have not shown any short-term or emergency supply problems. Exhibit K is a chart showing the
historical standing groundwater levels as measured at Lodi City wells from 1962 through 1995 and the
historical rainfall measurements. Again, this shows that drought conditions have not had a short-term
effect on groundwater supply.
MISCELLANEOUS
-The City of Lodi offers free inspections of water user facilities and water use patterns. There have
been no distribution system water audits nor any plans for one in the future.
-Without all users or areas metered, a distribution system water audit would not be feasible and
therefore none are planned.
-City water department crews are trained in the use of equipment to detect water leaks when there is one
suspected.
-All reports of water leaks are investigated and any applicable repairs made.
-Large landscape irrigation water customers were required to submit an "Irrigation Water Conservation
Plan". These submitted plans resulted in discussions and implementations of water -saving irrigation
measures.
GAVMW1URBWP95E.D0C 12 May 1. 1996 Public Hearing Draft
-Once -through cooling systems are not allowed on new construction. Many of the former once -through
cooling systems have been found and taken out of service. The abandonment of these systems has been
encouraged by high water bills and charges for the wastewater discharges resulting from their operation.
ADDITIONAL ELEMENTS
At this time there are no projections (20 years) to indicate that an additional water supply is needed.
The previously described water conservation efforts and ongoing discussions and negotiations with
eastern San Joaquin County water purveyors and EBMUD are dealing with the long term preservation
of the local groundwater (Exhibit L). Although recycling of treated wastewater back into the City of
Lodi water utility service area is not practical at this time, much of the treated wastewater is
reclaimed/recycled near the wastewater treatment facility as discussed earlier (Exhibit Q).
FIVE YEAR BUDGET
:Attached (Exhibit R) is the 1995-96 budget for Lodi's Water Conservation Program. In the next five
years, there are no major increases in expenditures anticipated other than normal inflationary increases
expected in salaries, supplies, postage, and services.

WATER vIANAGEivIENT PROGR4:lIS TO IMPLEMENT IN THE NEXT FIVE YEARS
The City of Lodi Water/Wastewater Division plans on continuing to fund the current comprehensive
water conservation program. Water meters will continue to be installed on all new or upgraded
commercial and industrial water customers. The State of California requirement for Ultra -Low -Flow
toilets is being enforced. The City has adopted the States Water Efficient Landscape Ordinance relating
GAWV MURBWP95E.DOC 13 May 1, 1996 Public Hearing Draft
T
to requirements on landscape construction The use of reclaimed/recycled water in the area of the City's
wastewater treatment facility will be expanded as discussed earlier.
SUMMARY
The City of Lodi has demonstrated major reductions in water -use patterns through the current Water
Conservation Program. The additional State -mandated water efficient landscape, low flow toilet, and
metering programs may also have marginal effects on water -use patterns in Lodi. The water supply
outlook for the City of Lodi foresees no short-term water supply shortages. The City will continue the
successful conservation program practices and continue to participate in conjunctive use negotiations for
the longi term water supply improvement of the area.
