AGENDA TITLE: Set a Public Hearing for July 18, 2001, to Consider Adopting the Update of Lodi's
Urban Water Management Plan
MEETING DATE: June 20, 2001
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council set a public hearing for July 18, 2001, to consider
adopting the update of Lodi's Urban Water Management Plan.
BACKGROUND INFORMATION: During the 1983/84 Regular Session, the California Legislature
enacted Assembly Bill 797, and as subsequently amended, created
Water Code Section 10610, et seq., known as 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. The current update was
performed with the assistance of Brown and Caldwell, consulting engineers, and is the third update of
Lodi's Urban Water Management Plan. The adoption process requires a public hearing and adoption by
the City Council. Staff will seek additional policy direction following the hearing.
The Plan updates Lodi's historical and projected population and water use, water rates, and water
metering program status. There are substantive changes from the previous plan. Much more attention is
given to the groundwater overdraft problem and to conservation measures, including metering.
A copy of the updated Urban Water Management Plan (approximately 75 pages) is available for review by
the public in the Public Works Department, the City Clerk's Office, and the Lodi Library.
FUNDING: None required.

In Memory of ORSON LAAM JR.
Pictured on the cover is the recently completed low water demand landscaping
(xeriscape) project at Lodi Municipal Well No. 11 R, 824 East Turner Road. This
xeriscape project is dedicated to the Lodi's first Water Conservation Coordinator Orson
Laam, Jr., who passed away unexpectedly on Friday, May 19, 2000 at the age of 58
following a lengthy battle with cancer. On April 18, 1990 Orson was hired as a Deputy
Water Conservation Officer. In 1991 he was promoted to the Water Conservation
Officer eventually handling both the enforcement and in -school education programs. In
January 1998 Orson Laam became Lodi's first full-time Water Conservation
Coordinator. Orson's favorite aspect of his job was visiting Lodi grade schools,
teaching water science and conservation to children. (From 1996 — 1998 he averaged
over 250 school presentations per year.) He dealt fairly with the public and was
pleasant and caring co-worker. A former professional radio DJ, Orson always had a big
smile and warm hello for everyone he came in contact with. We will deeply miss our
friend, co-worker and dedicated water conservation educator.

EXECUTIVE SUMMARY
This Plan is the year 2000 Urban Water Management Plan as required by the Urban Water
Management Planning Act and it serves as the long-term water supply plan for the City of Lodi
(City). The purpose of this Plan is to ensure the efficient use of available water supplies, describe and
evaluate the existing water system and historical and projected water use, and evaluate current and
projected water supply reliability as required by the Urban Water Management Act (Act).
Description of Existing Water System
The City of Lodi Water Utility is the only water purveyor in the City and serves approximately
16,753 connections. Lodi is located in the northern San Joaquin Valley bordered to the north by the
Mokelumne River. Groundwater from 24 active wells with a combined capacity of 34,225 gallons
per minute (gpm) is the sole source of water supply for the City of Lodi. The City's distribution
system consists of one pressure zone, two storage facilities, a pumping station, and the piping
system.
Historical and Projected Water Use
The year 2000 population in Lodi is 57,935 people and is expected to reach 86,088 in 2020. Water
demands through the year 2020 are estimated based on a 2.0 percent annual water demand growth
rate estimated by the City of Lodi's Public Works Department. Table ES -1 presents the projected
water demands through year 2020.
Table ES -1. Total Projected Water Demands
a acre-feet/year
Water Supply Quantity
Groundwater is currently the sole source of water for the City. From 1990 through 1999,
groundwater use averaged 14,787 ac-ft/yr. The groundwater basin is considered to be over drafted.
The City will have to take steps to reduce overall groundwater pumping by itself and/or others. For
the purpose of this study, it is estimated that the available sustainable groundwater supply is
approximately equal to 1980 pumping, or 12,000 ac-ft/yr. This assumption regarding sustainable
groundwater supply is only an approximation since the safe yield of the groundwater basin
underlying the City has not been defined. Given this assumption, the City does not have a
sustainable water supply for preventing over draft through the year 2020. Given current practices,
however, the City will still be able to pump sufficient groundwater during this over drafting period.

ES -2
A water supply reliability comparison is made in Table ES -2 for the year 2020, considering three
water supply scenarios: an average/normal water year; single dry water year; and multiple dry water
years. As shown in Table ES -2, the water supply would be overdrafting during multiple dry years.
Table ES -2. Water Supply Reliability, 2020, ac4t/yr
Units of measure: ac-ft/yr
a Based on 1980 pumping rate.
Water Conservation Best Management Practices
The results of an economic analysis conducted on several of the water conservation Best
Management Practices (BMPs) shows that all analyzed BMPs are not economical to implement
except for BMP 5 (Large Landscapes Conservation Programs and Incentives), and BMP 4 (Metering
of Residential Customers).
Recycled Water
At this time, the use of recycled water is not a viable option at this time to reduce the total water
demand in the City's water service area because it is a significant distance from the source of
recycled water at the White Slough Water Pollution Control Facility. The estimated $7.8 million cost
of installing pumping facilities and a pipeline to convey recycled water to the service area from the
wastewater treatment plant is considered to be expensive at this time compared to the cost of
available groundwater. The recycled water use of approximately 4,500 acre-feet per year surrounding
the treatment plant, however, does decrease the amount of regional groundwater pumping in the
area and can be considered a form of indirect recycling. The City intends to pursue the use of
recycled water if it becomes a more economically feasible option.
Recommendations
1. Because the City's groundwater supply is not sustainable to prevent overdraft over the long
term, the City should continue participation in the Northeastern San Joaquin County
Groundwater Banking Authority towards the development of a conjunctive use program to
reduce the overall pumping of groundwater in the area.
2. It does not appear economically feasible at this time to partially meet water demands in the
City's water service area through use of recycled water. The estimated $7.8 million cost of
installing pumping facilities and a pipeline to convey recycled water to the service area from
the wastewater treatment plant is considered to be expensive at this time compared to the
cost of available groundwater. The City should reassess this issue in five years and continue

to provide treated water for reuse on lands surrounding the White Slough Water Pollution
Control Facility to minimize the amount of groundwater pumping in the region.
Continue with current water conservation efforts. Consider implementing the cost effective
BMP 5 (Large Landscapes Conservation Programs and Incentives), BMP 9 (CII
Conservation), BMP 14 (Residential ULF1), and BMP 4 (Metering of Residential
Customers). The City should explore partnering with other utilities and funding
opportunities to help implement water conservation BMPs.
4. Track the development of upcoming drinking water standards that may impact the
groundwater supply. These standards include arsenic, radon, and the groundwater rule.
5. To maintain groundwater supply capacity, the City should rehabilitate or replace any older
wells as they reach the end of their useful lives.
6. Establish a process to record BMP implementation and measure the resulting water savings
resulting from BMP implementation.

INTRODUCTION
This Urban Water Management Plan (Plan) addresses the City of Lodi (City) Water Utility (Utility),
which provides water to approximately 16,753 connections, serving a population of 57,935 people
within the City's boundaries. This Plan is the year 2000 Urban Water Management Plan as required
by the Urban Water Management Planning Act (California Water Code Division 6, Part 2.6, Sections
10610 through 10640) and it serves as the long-term water supply plan for the City. The remainder
of this chapter provides an overview of the Plan, previous reports, conduct of the study, and public
participation.
1.1 Urban Water Management Planning Act
The purpose of this Plan is to ensure the efficient use of available water supplies, describe and evaluate
the existing water system and historical and projected water use, and evaluate current and projected
water supply reliability as required by the Urban Water Management Act (Act). The Act became part
of the California Water Code with the passage of Assembly Bill 797 during the 1983-1984 regular
session of the California legislature. The Act 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 adopt and submit an Plan every 5 years to the California Department of Water Resources
(DWR). Subsequent assembly bills have amended the Act. The Urban Water Management Plan
checklist is presented in Appendix B. This checklist is requested by DWR and is to facilitate review of
this plan.
1.2 Previous Reports
The City's Urban Water Management Plan was first developed in 1990, which addressed water supply
and demand for the City of Lodi. The 1990 Plan and 1995 Plan update were prepared by the City.
The 1995 update included a description of the water system, historical and projected water use, water
supply alternatives, recycled water use, water conservation programs, and a water shortage contingency
plan.
1.3 Public Participation
The Act requires the encouragement of public participation and a public hearing regarding the
Water Management Plan. This hearing provided an opportunity for Lodi's customers/residents and
employees in the area to learn about the water supply situation and the plans for providing a reliable,
safe, high-quality water supply for the future. The hearing also allowed people to ask questions
regarding the current situation and the viability of future plans. This Plan was finalized after the
public hearing.
A public hearing was held at a regular meeting of the Lodi City Council. Information regarding the
public hearing is included in Appendix G (will be added following the hearing and adoption).

CHAPTER
DESCRIPTION OF EXISTING WATER SYSTEM
This chapter describes the City of Lodi Water Utility system (Utility) and includes a description of
the service area and climate, the groundwater wells, the reservoirs, and the piping system. The water
system's water supply is described in Chapter 4.
2.1 Description of Service Area
The City of Lodi Water Utility is the main water purveyor for the City of Lodi. The City's boundary
is the water utility's service area with a few minor connections outside of the City's boundaries. The
Utility serves approximately 16,753 connections in the City, which is in the Northern San Joaquin
Valley in San Joaquin County and bordered to the north by the Mokelumne River. The Utility
service area is essentially the City's boundaries and characterized by a mixture of residential,
commercial, and industrial land use. The terrain is essentially flat. Historical and projected
population is addressed in detail in Chapter 3.
2.2 Climate
The City of Lodi has cool and humid winters, and hot and dry summers. Lodi's average daily
temperature ranges from 37 to 90 degrees Fahrenheit, but the extreme low and high temperatures
have been 11 and 111 degrees Fahrenheit, respectively (Western Regional Climate Center, 1999).
The historical annual average precipitation is approximately 18 inches. The rainy season begins in
November and ends in March. Average monthly precipitation during the winter months is about 3
inches, but records show that the monthly precipitation has been as high as 9.7 inches and as low as
0 inches. Relative humidity in the region ranges from 26 percent to 91 percent. Low humidity
usually occurs in the summer months, from May through September. The combination of.hot and
dry weather during the summer results in high water demands during the summer.
2.3 Water Supply Facilities
Groundwater from 24 wells is the only source of water supply for the City of Lodi. Currently, all
wells are active production wells. The locations of the groundwater wells in Lodi are illustrated in
Figure 2-1. Well 1 OR has been permanently abandoned.
2.3.1 Wells. Twenty-four wells with a combined capacity of 33,695 gallons per minute (gpm)
provide the City of Lodi's annual water production. The wells operate automatically on water
pressure demand and pump directly into the distribution system. The water is periodically
chlorinated three to six weeks per year. The current capacity of existing wells is surni arized in
Table 2-1. Several of the wells have granular activated carbon (GAC) treatment to remove
dibromochloropropane (DBCP).

2.4 Distribution System
The City of Lodi's distribution system consists of an elevated storage tank, one storage facility and
pumping station, and the piping system. A one million gallon storage tank, located east of Highway
99 on Thurman Street, stores groundwater from nearby wells to meet peak hour demands and fire
flows. The 100,000 gallon elevated storage tank is located on North Main Street. The storage
facilities and their capacities are given in Table 2-2.
The distribution system ranges in size from 14 -inch mains down to 2 -inch mains. The entire
distribution system consists of approximately 207 miles of pipe. Pipe size distribution is included in
Table 2-3. The City has commenced a pipe replacement program to reduce system leaks.

CHAPTER 3
HISTORICAL AND PROJECTED WATER USE
Water demand projections provide the basis for sizing and staging future water facilities. Water use
and production records, combined with projections of population and urban development, provide
the basis for estimating future water requirements. This chapter presents a summary of available
demographic and water use data and the resulting projections of future water needs for the City of
Lodi.
3.1 Population and Housing
Historical population and housing data were obtained from the City of Lodi. An annual population
growth rate of 1.5 per year was obtained from the Lodi Wastewater Master Plan (West Yost &
Associates, 2001).
It is estimated that the current population in Lodi is approximately 57,935 people. This population
is expected to reach 78,030 by 2020 based on the assumed annual growth rate of 1.5 percent. A
summary of the historic and projected population and housing in Lodi is presented in Table 3-1 and
illustrated in Figure 3-1.
The number of connections to the City's water system per year for the last ten years is shown in
Table 3-2. The number of connections by customer classification, as counted by the City of Lodi in
the year 1999, are shown in Table 3-3. There has been significant growth in the number of industrial
connections over the last five years.

In summary, from 1994 to 1999, the City of Lodi population increased 5.6 percent, which is a
growth rate of approximately 1.1 percent per year. Population is expected to increase by 35 percent,
from 57,935 in 2000 to 78,030 in 2020.
3.2 Historical Water Use
Records of historical water production were obtained from the City of Lodi Public Works
Department. These data include maximum day and annual water production. Water production is
the volume of water measured at the source, which includes all water delivered to residential,
commercial, and public authority connections, as well as unaccounted-for water.
3.2.1 Annual Water Production. Groundwater production from 1970 to 1999 is presented in
Table 3-4. Total water production in 1999 was 16,587 acre-feet (ac -ft). Historical annual water use
for the last 23 years is presented in Table 3-5. Water use by customer class is not available because
most of the City's customers are not metered.

3.2.2 Maximum Day Demand. Daily demand fluctuates throughout the year based primarily on
seasonal climate changes. Water demands are significantly higher in the summer than the winter.
System production facilities must be sized to meet the demand on the maximum day of the year, not
just the average. Water systems are sized to meet the greater of either the maximum day demand
plus fire flow or peak hour demand. Fire flow and peak hour demand are not addressed in this
report.
The average day and maximum day demands for the years 1977 through 1999 are presented in
Table 3-5. The maximum day demand in 1999 was 19,667 gpm, in comparison to the total well
production capacity of 33,695 gpm. The ratio between average and maximum day demands
provides a maximum day peaking factor that can be used to scale annual demand projections to
maximum day levels. The average maximum day peaking factor from 1990 to 1999 is 1.94.

3.2.3 Unaccounted-for Water. Unaccounted-for water use is unmetered water use such as from
fire protection and training, system and hydrant flushing, sewer cleaning, construction, system leaks,
and unauthorized connections. Unaccounted-for water can also result from meter inaccuracies.
Since the City of Lodi's system is not completely metered, data are unavailable for determining the
percent of unaccounted-for water. Unaccounted-for water is generally assumed to be approximately
10 percent of total water production.
3.3 Unit Water Use
Historical unit water use expressed as gallons per connection per day (gpd/connection) and as
gallons per capita per day (gpd/capita) are shown in Table 3-6. These unit demands include
unaccounted-for water.

are shown in Table 3-7 and illustrated on Figure 3-2. By 2020, average annual water demands are
expected to increase by 36 percent, from 14.8 mgd (16,587 ac-ft/yr) in 1999 to 20.3 mgd (22,727 ac-
ft/yr) in 2020. Reductions to water use due to conservation measures taken in the future are not
reflected in the projected water demands.

CHAPTER 4
WATER SUPPLY QUANTITY
The City of Lodi currently uses groundwater as its sole source of supply. This chapter describes the
groundwater basin, current and projected water supplies, water supply reliability, and water shortage
expectations.
4.1 Groundwater
This section describes the groundwater supply and its physical and legal constraints. No surface
water is currently used in the City of Lodi water system. However, as a result of a 1930's lawsuit, the
City does have a limited entitlement to 3,600 acre-feet of surface water (21 percent of the City's 2000
demand) from the Mokelumne River/East Bay Municipal Utility District. The availability of this
water to the City is under question due to the number of conditions specified under this "Lodi
Decree".
4.1.1. Description. The groundwater basin underlying the City of Lodi is part of the longer San
Joaquin Valley groundwater basin. The groundwater basin in the Lodi area occurs under unconfined
and semi -confined conditions. The Mehrten Formation is the most productive fresh water -bearing
unit.
The City of Lodi is located within the geomorphic province known as the Central Valley, which is
divided into the Sacramento Valley and the San Joaquin Valley. The Central Valley is a large,
northwestward -trending, asymmetric structural trough that has been filled with several miles of thick
sediment (USGS 1986). The City of Lodi lies within the San Joaquin Hydrologic Basin (DWR,
Bulletin 118) which straddles portions of both the Sacramento and San Joaquin Valleys. Sediments
of the San Joaquin Valley consist of interlayered gravel, sand, silt, and clay derived from the adjacent
mountains and deposited in alluvial -fax, floodplain, flood -basin, lacustrine, and marsh environments.
Hydrogeologic units in the San Joaquin Basin include both consolidated rocks and unconsolidated
deposits. The consolidated rocks include 1) the Victor Formation, 2) Laguna Formation, and 3) the
Mehrten Formation. The consolidated rocks generally yield small quantities of water to wells except
for the Mehrten Formation which is an important aquifer (DWR, internet site). The unconsolidated
deposits include 1) continental deposits, 2) lacustrine and marsh deposits, 3) older alluvium, 4)
younger alluvium, and 5) flood -basin deposits. The continental deposits and older alluvium are the
main water -yielding units in the unconsolidated deposits.
Groundwater levels in the City of Lodi area are generally decreasing. The groundwater levels also
fluctuate over time depending on precipitation, aquifer recharge, and pumping demands. This
decrease in groundwater levels is an indicator of an overdrafted groundwater basin. Groundwater
elevations relative to mean sea level (MSL) and the corresponding annual precipitation from 1927
through 2000 are shown in Figure 4-1. Overall, the average annual decrease in groundwater levels
from 1927 to 2000 has been 0.35 feet per year. Generally, groundwater elevations have decreased
with the increase in population and water production. However, annual rainfall also influences
groundwater elevation. The groundwater level increase from 1981 to 1984 can be partially attributed
to the increase per year in annual rainfall from 1981 to 1983. Groundwater elevations for

the years 1927 to 1961 were obtained. from East Bay Municipal Utility District (EBMUD) for the
City's six square mile area. Groundwater elevation data from 1962 to the present were obtained
from the City's Public Works Department for Well No. 2, one of the oldest production wells in
Lodi.
4.1.2 Physical Constraints. The City of Lodi's system currently has twenty-four active wells with
a total pumping capacity of 48.5 mgd. The physical constraints on the groundwater supply are the
pumping capacity of the existing wells. However, the fact that the groundwater basin is overdrafted
means that in the long term the groundwater supply is something less than the current annual
pumping rate.
The declining groundwater basin is a result of the groundwater extraction by all groundwater
pumpers in the area. This includes groundwater pumping by other cities, agriculture, private well
owners, as well as the pumping by the City of Lodi. The City will likely have to reduce its
groundwater pumping in the long-term as part of what will have to be a regional effort to stabilize
the groundwater basin. This could be accomplished by three possible approaches:
1. The City reduces its demand and groundwater pumping to a yet to be defined sustainable rate.
2. The City utilizes surface water as an additional supply to offset reductions in groundwater
pumping. A conjunctive use project could be implemented that utilizes surface water as a supply
in wet years, thereby allowing for a net reduction in groundwater pumping.
3. The City helps provide surface water to others, such as agricultural customers, to reduce
groundwater pumping in the area by others.
4.1.3 Legal Constraints. There are no legal constraints on groundwater pumping. In California,
the State is not authorized by the Water Code to manage groundwater. California landowners have
a correlative right to extract groundwater for beneficial use. As a municipal water supplier, the City's
appropriate rights are junior to overlying landowners.
4.2 Groundwater Quality
The United States Environmental Protection Agency (EPA) is currently considering or has
implemented several new or revised drinking water standards. The Radon, Arsenic, and the
Groundwater Rule may impact the City of Lodi.
Radon is not currently regulated, although EPA recently proposed a maximum contaminant level
(MCL) of 300 picoCuries/liter (pCi/L). Water systems in states that develop multimedia mitigation
(NIMM) plans to address indoor air radon levels, or in absence of a state MMM program, that initiate
enhanced indoor air radon level reduction programs, would be able to comply with an alternate MCL of
4,000 pCi/L. Treatment for compliance with the proposed radon standard may need to be provided to
all subject groundwater sources within the specified time frame following promulgation of the final rule.
The average radon concentration in Lodi's 24 wells from 1997 to 1999 was 450 pCi/L.
As required by the 1996 amendments to the Safe Drinking Water Act (SDWA), the arsenic standard
in drinking water has been recently changed to a MCL of 10 µg/L from the previous 50 µg/L
P:\20000\20650 Lodi UWMP\WMP\5-01 Final Draft Report\Chapter 4\Chapter 4.doc
)WA30•May-01
4-4
standard. None of the 24 Lodi wells sampled from 1997 to 2000 contained arsenic concentrations
higher than the new standard of 10 µg/L. Therefore, the new arsenic standard is not an issue for
the City.
Dibromocbloropropane (DBCP) was a chemical previously used by farmers in the Lodi area to
control nematodes in vineyards and other crops. DBCP was banned in California in 1977, but is still
present in trace levels in some groundwater supplies. The MCL for DBCP has been set at 0.2
micrograms per liter (µg/L). The year 2000 average concentration of DBCP in water delivered from
Lodi's 24 wells was 0.04 pg/L. Approximately a fourth of Lodi's wells have granular activated
carbon (GAC) filters to remove DBCP, while the remaining wells have no detectable or trace
amounts of DBCP (City of Lodi Public Works Department, 2000).
The U.S. EPA is proposing the Ground Water Rule (GWR), which contains measures to establish
multiple barriers to further protect against bacteria and viruses in drinking water from ground water
sources. The proposed GWR will specify when corrective action (including disinfection) is required
to further protect groundwater system consumers from bacteria and viruses. The GWR is scheduled
to be issued as a final regulation in summer 2001. The City of Lodi may be required to disinfect (i.e.
chlorinate) its groundwater sources as a result of this proposed rule.
4.3 Current and Projected Water Supplies
The projected annual sustainable water supply and demand for the Lodi system is compared and
summarized in Table 4-1. Recycled water supply is addressed in Chapter G. As described earlier, the
groundwater basin is in an overdraft condition. Therefore, the sustainable groundwater extraction
rate for the City is likely something less than current annual pumping rates. For the purposes of this
study, the sustainable groundwater supply is assumed to be approximately equivalent to the 1980
pumping rate, or approximately 12,000 ac-ft/yr. This assumption regarding sustainable groundwater
supply is only an approximation since the safe yield of the groundwater basin underlying the City has
not been defined. As a comparison, the 1990 through 1999 groundwater use averaged 14,787 ac-
ft/yr. As shown in Table 4-1, the water supply is not adequate to meet projected demands.

wet or dry years. The estimated year 2020 water supply available in average, dry, and multiple dry

Based on current conditions. Recycled water may be available by 2020.
4.5 Water Shortage Expectations
Short-term groundwater supply shortages are not expected. The City currently has six wells fitted
with emergency diesel -powered generators during power outages, which increases the reliability of
supply. As described earlier, the groundwater basin is in an overdraft condition that will require the
City to eventually take steps to reduce overall groundwater pumping. Continuing decline of
groundwater levels could result in the need to drill deeper wells.
The City of Lodi is actively participating in acquiring future water supplies in the northeastern San
Joaquin County area. The City is part of the Northeastern San Joaquin County Groundwater
Banking Authority whose purpose and goals include negotiating a conjunctive use project with the
East Bay Municipal Utility District (EBMUD). The latest conjunctive use water planning and
principles and negotiations with EBMUD are included in Appendix D.

4.5 Water Shortage Expectations
Short-term groundwater supply shortages are not expected. The City currently has six wells fitted
with emergency diesel -powered generators during power outages, which increases the reliability of
supply. As described earlier, the groundwater basin is in an overdraft condition that will require the
City to eventually take steps to reduce overall groundwater pumping. Continuing decline of
groundwater levels could result in the need to drill deeper wells.
The City of Lodi is actively participating in acquiring future water supplies in the northeastern San
Joaquin County area. The City is part of the Northeastern San Joaquin County Groundwater
Banking Authority whose purpose and goals include negotiating a conjunctive use project with the
East Bay Municipal Utility District (EBMUD). The latest conjunctive use water planning and
principles and negotiations with EBMUD are included in Appendix D.

CHAPTER 5
WATER CONSERVATION BEST MANAGEMENT PRACTICES
Water conservation is a method available to reduce water demands, thereby reducing water supply
needs for the City of Lodi (City). This chapter presents an analysis of water conservation best
management practices (BMPs) and a description of the methods and assumptions used to conduct
the analysis.
The unpredictable water supply and ever increasing demand on California's complex water resources
have resulted in a coordinated effort by the DWR, water utilities, environmental organizations, and
other interested groups to develop a list of urban BMPs for conserving water. This consensus -
building effort resulted in a Memorandum of Understanding Regarding Urban Water Conservation
in California (MOU), as amended September 16, 1999, among parties, which formalizes an
agreement to implement these BMPs and makes a cooperative effort to reduce the consumption of
California's water resources. The BMPs as defined by the MOU are presented in Table 5-1. The
MOU is administered by the California Urban Water Conservation Council (CUWCC). The City of
Lodi is not a signatory of the MOU.
The value to the City of signing the MOU, which is a voluntary agreement, cannot be quantified. If
the City desires to demonstrate that water use efficiency is being addressed to industry standards of
practice, then signing the MOU should be considered. Being a signatory of the MOU may be a
future requirement to receive water project grant and loan funding from the State.
The MOU requires that a water utility implement only the BMPs that are economically feasible. If a
BMP is not economically feasible, the water utility may request an economic exemption for that
BMP. The BMPs as defined in the MOU are generally recognized as standard definitions of water
conservation measures.

5.1 Current Water Conservation Program
Water conservation in Lodi is supported by the City Council and Lodi's citizens. The current
program consists mainly of outdoor watering restrictions enforced by water conservation patrol
staff, public education, and an in -school education program.
The City has had an enforced ordinance for water conservation continuously since 1977 and it has
developed into one of the most comprehensive on-going programs functioning in the San Joaquin
Valley. A copy of the conservation ordinance information sheet is included in Appendix C in
English and Spanish. 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 staff'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 water customers, and notices of violation issuance for water wasting. The
ordinance information sheet is given out when water wasting is observed. All violations are
recorded on a violation card (Appendix C) 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 Appendix C.
A Water Educational Program was introduced to Lodi elementary schools in 1986. This program
supplements and enhances the City of Lodi's 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 10 schools, including four parochial schools, within the Lodi City limits. In 1998, there
were 252 classroom presentations. The program includes water science demonstrations with the
objective of instilling water awareness and providing information about Lodfs 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
Appendix C.
The City water conservation program participates in local fairs, including the Crime Prevention Fair
(sponsored by Lodi Police Dept.), the Conservation Fair (sponsored by local agencies concerned
with conservation), and the Lodi Grape Festival and Harvest Fair, and other special events. Staff
converses with the fairs' visitors about Lodi's water conservation program and answers questions
they might have concerning water issues. The City of Lodi also hands out information sheets and
conservation kits and holds 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.
5.2 Economic Analysis Methodology and Assumptions
An economic analysis was conducted for 6 of the 14 BMPs (Table 5-1) that are described in the
MOU and that the City of Lodi is not currently implementing (i.e., BMP nos. 1, 4, 5, 6, 9 and 14).
BMP 4 is analyzed for two cases. Case 1 consists of installing meters and meter boxes at all pre -
1992 connections. Case 2 consists of installing meters only at all post 1992 connections. The intent
of the analysis is to determine if the BMPs not being implemented are not economically feasible.
The remaining BMP 2 is not analyzed because the City is already currently implementing it.
Economic analyses were not done for BMPs 3, 7, 8, 10, 11, 12, and 13 because they are essentially
non -quantifiable, but essential to the success of those BMPs that are quantifiable. These BMPs are
considered non -quantifiable because the water savings cannot be accurately estimated. These non -
quantifiable BMPs have already been implemented by the City.
Assumptions used in the economic analysis for each BMP are described in Table E-1 (Appendix E).
Directly beneath each assumption is a brief description of the rationale and/or supporting evidence
for that assumption. Common assumptions for all BMPs are the value of conserved water
($500/ac-ft), and the real discount rate (6.15%). The real discount rate was calculated from the
assumed real cost of money (8.82%) and the assumed long-term inflation rate (2.529/6) using the
precise conversion method (A&N Technical Services, 2000. pg A-2). The value of conserved water
includes estimated costs of new well construction and the costs of importing surface water to reduce
the groundwater overdraft. Also included are non -water utility benefits, such as reduced wastewater
conveyance and treatment costs. A breakdown of the number of metered and unmetered
connections for each customer category in 1999 is presented in Table 5-2. State law requires that
meters will be installed on new residential connections.

The economic analysis was performed using Microsoft® Excel 97, a spreadsheet program. A
separate, customized worksheet for each BMP is presented in Appendix E. Each BMP economic
analysis spreadsheet projects, on an annual basis, the number of interventions and the dollar values
of the benefits and costs that would result from implementing a particular BMP. Terms and
formulas that are common to all the worksheets are defined in Table 5-3.

5.3 Economic Analysis Results
The results of the economic analysis in terms of the benefit/cost (B/C) ratio, the simple pay -back
period, the discounted cost per ac -ft of water saved, and the net present value (NPV) per ac -ft of
water saved for each BMP are presented in Table 5-4.
Annual water savings and costs for each of the BMPs with a B/C ratio equal to or greater than one
are presented graphically on Figures 5-1 and 5-2 and summarized in Table 5-5. The number of
annual interventions required for each BMP and the annual expenditure necessary if the City of Lodi
is to be in compliance with the MOU for all cost effective, quantifiable BMPs is presented in Table
5-5. Interventions are actions or activities required to implement each BMP.
The water savings and costs associated with BMPs 3, 7, 8, 10, 11, 12, and 13 are not included in
Figures 5-1 and 5-2 and Table 5-5, since no specific level of effort is defined in the MOU for these
BMPs.
5.4 Additional Issues
This section describes additional issues required to be addressed by the Urban Water Management
Planning Act. Non -economic factors, including environmental, social, health, technological and
customer impacts are not thought to be significant in deciding which BMPs to implement. No
water supply projects are currently planned that would supply water at a higher unit cost.
The City of Lodi has the legal authority to implement the BMPs.

CHAPTER 6
RECYCLED WATER
The purpose of this chapter is to provide information on recycled wastewater and its potential for
use as a water resource in the service area of Lodi. The elements of the chapter are (1) the quantity
of wastewater generated in the service area, (2) description of the collection, treatment, and
disposal/reuse of that wastewater, (3) the current plans for water recycling, and (4) the potential for
water recycling in the service area.
6.1 Wastewater Generation
Municipal wastewater is generated in the service area from a combination of residential, commercial,
and industrial sources. The quantities of wastewater generated are proportional to the population
and the water use in the service area. Estimates of average wastewater flows for the present and
future conditions are presented in Table 6-1. The source of the estimates is the population
projection in Chapter 3 and an assumed per capita unit flow of 116 gal/capita/day given in the
Wastewater Master Plan (West Yost & Associates, 2001), which includes commercial and industrial
use.

Note: Current treatment plant capacity is 8.5 mgd (9,550 ac-fVyr).
6.2 Wastewater Collection
The City of Lodi owns, operates, and maintains the wastewater system that serves the community.
The sewer system consists of gravity sewers up to 48 inches in diameter, pumping stations, and force
mains to collect wastewater from residential and commercial customers. The wastewater is collected
and discharged to trunk sewers and interceptors and conveyed to the White Slough Water Pollution
Control Facility (WSWPCF) for treatment. Industrial wastewater from a cannery is collected and
conveyed separately from the residential wastewater to the WSWPCF for treatment or direct
irrigation.
6.3 Wastewater Treatment and Recycling
The City owned and operated White Slough Water Pollution Control Facility (Facility) provides the
wastewater treatment service for the City of Lodi and is located 6 miles outside of the water service
area. The residential and commercial wastewater at the Facility undergoes conventional secondary
treatment with activated sludge and chlorination/dechlorination. The Facility has a capacity to treat
8.5 million gallons per day (9,550 ac-ft/yr) of residential and commercial wastewater. The City
would have to revise its discharge permit and implement some process improvements to be able to
P:\20000\206501.odi UWMP\WMP\5-01 Final Draft Report\Chapter 6\chapter 6.doc
JW:\30-May-01
6-2
treat to the full 8.5 mgd capacity. Currently, approximately 6.6 mgd (7,400 ac-ft/yr) of wastewater is
treated at the Facility. Industrial process water from a nearby cannery is transported in a separate
trunk line to the WSWPCF where it is stored in 45 acres of existing ponds for direct flood irrigation
of feed and fodder crops.
All of the treated effluent from the Facility is recycled during the summer months. During the
winter months, the treated effluent that is not recycled is discharged to White Slough which is part
of the San Joaquin Delta. Adjacent to the WSWPCF, the City owns in excess of 1,000 acres of land
and leases 641 acres to local farmers for the cultivation and harvesting of feed and fodder crops not
intended for human consumption. The Facility has the flexibility to irrigate with domestic flow and
cannery process water. All of the industrial process water influent is recycled for irrigation and
ponding, If a process upset should occur, the domestic flow can be stored in holding ponds and
further treated before discharging water to the Delta. In recent years, the City has also supplied
recycled water from the domestic treatment process to produce steam for a 49 -megawatt natural gas
powered generator, and to replenish mosquito fish -rearing ponds. Total 1999 recycled water use in
ac -ft outside of the water service area boundaries and surrounding the treatment plant is given in
Table 6-2. Recycled water use does not replenish the quantity of water pumped by the City, but
does reduce the pumping demand for groundwater and surface water near the Delta.

6.4 Potential Water Recycling in the Lodi Service Area
Presently, there are no plans to construct the six miles of transmission lines and pumping stations
needed to return treated wastewater to the water utility service area. The estimated $7.8 million cost
of installing pumping facilities and a pipeline to convey recycled water to the service area from the
wastewater treatment plant is considered to be expensive at this time compared to the cost of
available groundwater. Therefore, at this time, the recycled water supply for the service area is
projected to be 0 acre-feet per year for the next 10 years. The City will pursue the use of recycled
water should it become an economical supply. Some unknown quantity of recycled water is
anticipated by 2020.
Outside the City's water service area boundaries, there is a project currently pending that will utilize
400 acres of land at the WSWCPF for irrigation of a sports complex. Treated water supply currently
utilized on agricultural lands will require tertiary treatment before reallocation to this complex.
Upgrade of the treatment process to include tertiary treatment with filtration is expected by the year
2004. The agricultural and industrial reuse of treated water surrounding the WSWPCF does not
replace the groundwater pumped by the City but does reduce the amount of groundwater and
surface water use in the area. The additional source of treated wastewater offsets part of the
demand for groundwater in Lodi and can be viewed as a form of indirect recycling.

CHAPTER7
CONCLUSIONS AND RECOMMENDATIONS
Based on the results of the evaluation conducted in this report, the following recommendations are
made.
1. While the water supply is adequate to address average years, dry years, and multiple dry
years, the groundwater basin is in a general over draft condition. The City should take steps
to develop a conjunctive use program to reduce the overall pumping of groundwater.
2. At this time, it does not appear feasible to partially meet water demands in the City's water
service area through use of recycled water. The estimated $7.8 million cost of installing
pumping facilities and a pipeline to convey recycled water to the service area from the
wastewater treatment plant is considered to be expensive at this time compared to the cost
of available groundwater. The City should reassess this issue in 5 years and continue to
provide recycled water for reuse on lands surrounding the White Slough Water Pollution
Control Facility to minimize the amount of groundwater pumping in the region.
Continue with current water conservation efforts. Consider implementing the cost effective
BMP 5 (Large Landscapes Conservation Programs and Incentives), BMP 9 (CII
Conservation), BMP 14 (Residential ULFT), and BMP 4 (Metering of Residential
Customers). The City should explore partnering with other utilities and funding
opportunities to help implement water conservation BMPs.
4. Track the development of upcoming drinking water standards that may impact the
groundwater supply. These standards include arsenic, radon, and the groundwater rule.
5. To maintain groundwater supply capacity, the City should rehabilitate or replace any older
water mains and wells as they reach the end of their useful lives.
6. Establish a process to measure water savings resulting from BMP implementation.
7. Establish a process to keep a record of BMP implementation.

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. If you need extra watering due to fertilizer application or for new turfiseeding, please first notify the Water Conservation Office at 333-6829.
3. 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 fuming 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
into the gutter. Consult landscapers/gardeners/nurseries for improving your lawns water absorbing capacity and for other ideas.
4. 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.
5. Regularly replace your back-up batteries in your automatic sprinkler controls to prevent excess watering due to power failures or interruptions.

Water Conservation Education Program
Prepared by: George Sande, Water Conservation Officer
Frank Beeler, Assistant Water/Wastewater
Superintendent
THE CLASSROOM
Philosoph
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.
Procedure
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.
Also, if you can initially impress them with your observations of
their activities they are better conditioned to be receptive 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.

Teachers are invariably receptive and interested in the
presentations and nearly always do follow-up on some aspect of
what I did in their particular class. Many use the experience as
a language arts assignment and I have received literally hundreds
of letters from students or packets of students' art work along
with 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 PROGRAM
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 uniquein 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
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 ATT 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
theywant 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.

AGENDA TITLE: Approve the Joint Powers Agreement for the Northeastern San Joaquin County
Groundwater Banking Authority, Appoint a Representative and Two Alternates to
that Board, and Provide Policy Direction Regarding Participation in Successor Entity
to East San Joaquin Parties Water Authority for Future Surface Water Supplies
MEETING DATE: February 7, 2001
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council approve the joint powers agreement for the
Northeastern San Joaquin County Groundwater Banking Authority,
appoint a representative and two alternates to that Board, and provide
policy direction regarding participation in successor entity to
East San Joaquin Parties Water Authority for future surface water supplies.
BACKGROUND INFORMATION: On October 17, 2000, City staff briefed the City Council on water
supply activities including our membership in the East San Joaquin
Parties Water Authority (ESJPWA) and discussions with
North San Joaquin Water Conservation District (NSJWCD) and
East Bay Municipal Utilities District (EBMUD) on possible conjunctive -use water supply projects. The
Council concurred in the direction that was described. A copy of the report from that meeting is attached
(Exhibit A).
Staff has continued to work on these items, however, a recent development has initiated a sense of
urgency. EBMUD, Sacramento interests, and the Bureau of Reclamation have resolved many issues
regarding diversion of American River water to EBMUD via a pipeline from Sacramento to the EBMUD
aqueducts in San Joaquin County. (See Exhibit B for map and MOU.) The opportunity to participate in
this project is one that we and others in the County should not pass up; however, the time frame is
extremely short, as stated in the letter from the project partners to San Joaquin County (Exhibit C).
Since the ESJPWA agreement has expired, a new entity is needed to step up and take the lead in
representing interested parties. Management staff from the ESJPWA members met to discuss a new
entity and have drafted a new Joint Powers Agreement (Exhibit D). The organization's purpose and
goals are stated in Article 1. Given the accelerated time frame, the other agencies are all considering
this document in early February, in order to receive final approval from the Board of Supervisors by late
February. The name of the organization has been changed to more accurately reflect the geographical
area represented and the purpose of the organization.
The agreement provides for a representative from the City of Lodi plus two alternates. Two alternates
were recommended to help insure participation since a unanimous vote is required for any action. In the
past, the Board member was a member of the City Council and the alternate was the

Public Works Director. Staff feels that this, is appropriate. The second alternate could be either another
Councilmember, City staff member, or someone from the public. The main qualifications would be a
keen interest in water issues and the time to attend what is likely to be a high number of meetings in the
next few months.
In terms of policy direction, those described in Exhibit A are still generally valid from staff's prospective;
however, they are out-of-date given the latest developments in Sacramento County. The projects
described in Exhibit A are certainly lower in priority for EBMUD when compared to the Freeport project.
Also, it is very possible that unless the facility is oversized, there will only be a relatively small amount of
water available for San Joaquin County. Oversizing the project will take a significant effort on the part of
this County — an effort that will mean spending a substantial amount of money in a short time frame.
And EBMUD has made it clear they want their project to move forward quickly.
In terms of policy direction, staff feels that the City of Lodi should be prepared to speak up for roughly
15,000 to 25,000 acre-feet of water, at least in wet years. This will mean spending some money, both in
participating in the legal negotiations over project agreements and in preliminary engineering to examine
alternatives. These costs are unknown at this time, but could easily be in the six -figure range. Our use
of the water in the very long term would be to reduce our own use of groundwater. In the short term, the
water could be used for groundwater recharge or provided to other users to reduce groundwater
pumping. This policy direction would include continuing to move forward absent other members of the
JPA, if necessary.
Again, this is only policy direction at this point. No financial commitment is needed today. The County is
nearing completion of the county -wide Water Management Plan which will provide additional background
information to help in making a decision at a later date. Also, the City's Urban Water Management Plan
is nearing completion and will be available for public and Council review in a few weeks.
Staff will have additional information at the Council meeting on the 7th.
FUNDING: None needed at this time.

CITY OF LODI COUNCIL COMMUNICATION
AGENDA TITLE: Update on Water Supply Issues
MEETING DATE: October 17, 2000 (Shirtsleeve Session)
PREPARED BY: Public Works Director
RECOMMENDED ACTION: None — information only.
BACKGROUND INFORMATION: Following previous Council direction, City staff has, 1) continued to
work within its membership in the East San Joaquin Parties Water
Authority (ESJPWA), and 2) held discussions with North San Joaquin
Water Conservation District (NSJWCD) and East Bay Municipal
Utilities District (EBMUD) on possible conjunctive -use water supply projects. The purpose of this meeting
is to update the Council and the public on these activities and describe upcoming activities. .
The fundamental element of a conjunctive -use project is that excess surface water supplied from one
entity would either be stored in the local groundwater basin, or provided as additional surface water
replacing present groundwater use by a local entity, and then, in a drought, the "stored" groundwater
would be available to the supplying entity. While the concept sounds simple, issues surrounding the
details, both legal and technical, are complex and controversial in some minds. These issues are being
addressed as described below and our planned policy direction is shown in italics:
ESJPWA — This entity has served as a forum for local urban and agricultural water suppliers and
users, including EBMUD, to continue discussions and plan for future projects. ESJPWA has
confirmed its role as a planning authority and has formally stated that any specific projects are to be
undertaken by individuals or groups of members. The ESJPWA has continued the Beckman Test
Project to learn more about the fate of injected water into the groundwater basin to assist members
in planning a larger scale project.
We intend to continue this participation and strongly agree that actual projects would be best
handled by the ESJPWA's members.
■ San Joaquin Water Advisory Commission — This countywide commission is currently considering one
element related to implementing the recently revised County groundwater export ordinance. That
element has to do with possible amendments to State law regarding groundwater export. A
memorandum describing possible amendments has been drafted by legal counsel and is attached as
Exhibit A.
Without getting into the myriad of details, we intend to support changes that simplify'and make
conjunctive -use projects more likely to be implemented while allowing for a reasonable degree of
local control.

Integrated Storage Investigations and Countywide Groundwater/Surface Water Management Plan —
This ambitious and important study is a joint effort among the County, State and local water agencies
to develop a comprehensive water supply plan for San Joaquin County. The effort is being assisted
by a large steering committee in which we participate. A "Principles of Participation" statement is
attached as Exhibit B. One outcome of this work will be an updated computer model of the
groundwater basin, which includes surface water flow and use impacts. But the key outcome is a
preferred alternative consisting of a package of options, including projects, programs, policies and/or
operational strategies that offer a means for achieving plan objectives (see Exhibit C).
We intend to continue participation in this effort and work toward including conjunctive -use,
conservation, and recycling as potential elements of the Plan.
Potential project with Lodi and NSJWCD and/or EBMUD — Following ESJPWA's direction that
members actually implement projects, and past Council direction, staff has continued to work on a
possible project, focusing on what was formerly called the "10 -well project". The updated project
concept is attached as Exhibit D and would mainly involve EBMUD and NSJWCD. The concept
includes two elements that have led City staff to suggest that additional elements (and City
participation) be considered. One element is the concern over pumping wells within the agricultural
areas for export — that the increased pumping during a dry year could have an adverse impact on
adjacent ag wells. The other element is that the exported water will need to be filtered to remove
potential contaminants, mainly DBCP. Of the $25 million budget, nearly half is for filters.
The additional elements suggested would include the City as part of the project by using excess (off-
peak) capacity in our wells as all or part of the export wells, thereby minimizing the impact to
agricultural areas. The next element would include the City as one of the conjunctive users. The
City would use some surface water when it is available, thereby "banking" groundwater for export in
dry years. There are numerous feasibility and technical details to consider, as well as
legallinstitutional ones to work out on these elements. An updated conceptual outline is attached
(Exhibit E).
Staff intends to continue to work with NSJWCD and EMBUD on this project, including the
additional elements, and develop a scope of work for a study to address these details. This will
be brought back to the Council in the future for discussion and action. We also intend to
continue to work with NSJWCD in its efforts to secure surface water for direct use and/or
recharge.
FUNDING: None needed at this time.

Executive Summary
Beckman Test I/E Project
The Beckman Test Injection/Extraction Project (Project) was proposed
by the East San Joaquin Parties Water Authority (ESJPWA) in
conjunction with the East Bay Municipal Utility District (EBMUD) to
confirm that injection of Mokelumne River Aqueducts (MRA) water
via injection wells could be accomplished. The injection wells
pursuant to previous project proposals were anticipated to have a
capacity of 1,000 gpm in extraction and 500 gpm during injection.
The ESJPWA consists of the North San Joaquin Water Conservation
District, City of Lodi, Woodbridge Irrigation District, Stockton East
Water District, City of Stockton, Central San Joaquin Water
Conservation District, San Joaquin County and California Water
Service Company, a water purveyor in the City of Stockton. These
parties provided the funding for the project while EBMUD provided
the water supply from its MRA.
The Project was sited based on its proximity to the MRA. The Project
is located approximately one mile east of the intersection of the MRA
and State Highway 88, just south of Live Oak Road. This site has
groundwater conditions similar to many other areas of the ESJPWA
service area wherein the water table slope is fairly flat. A statement of
Project goals is contained in the Memorandum of Agreement (MOA)
between the ESJPWA and EBMUD. A copy of the MOA is included
in Appendix A.
The Project was designed and constructed in late fall 1997 and was
operational January 12, 1998. Due to the very high levels of
precipitation, both rain and snow in the mountains, the runoff in the
rivers serving the MRA system was very high (third largest in history).
This created turbidity in the MRA reservoir system, specifically
Pardee Reservoir. As a result, the turbidity limits set by ESJPWA for
injection were occasionally exceeded. Therefore, operations were
curtailed from time to time throughout the early part of the Project.
Operation of the injection well and its monitoring well took place from
January 12, 1998 (first day of activation) through the termination of
the availability of water supply by EBMUD on September 23, 1998.
Injection rates during the period ranged from a low of 500 gpm to as
high as 1,500 gpm. The rates of injection were held constant over
various periods of time to determine the ability of the aquifer to accept
BeckmanFina ftt6.doc i ROW E
water on a continuous basis over a long period of time. This was
important because one of the project goals was to be able to use the
data collected to develop design criteria for a subsequent project.
Approximately 107 million gallons (328 acre-feet) of water were
injected as part of the Project. Approximately 2.9 million gallons (8.9
acre-feet) of water were extracted.
All injection well projects experience well plugging (reduction in
injection rate capability) as a result of injection. Another goal of this
Project was to confirm that injection of untreated MRA water could
take place and the well could be rehabilitated after plugging occurred
to allow injection to continue. This was demonstrated during the
Project and at Project's end the injection rate capability of the system
was equivalent to that which was experienced at the beginning of
injection.
As a result of data developed during the test program it was possible to
develop an empirical formula for the plugging of the formation. The
variables in the formula are volume of injected water and its turbidity
and a modified value of specific injection (injection rate divided by
drawup). This plugging formula will help predict the time between
rehabilitation efforts for future project injection wells.
Biological growth and chemical reactions, in addition to turbidity, can
Pt nIc anFinaIRnt6.doC II F30VLE
affect the rate of plugging experienced with injection wells. This
Project did not include the evaluation of biological growth or chemical
'
reactions. However, neither was considered to be highly likely due to
several factors. Since the water had chlorine residual at the time of
injection, biological growth was not anticipated. The downhole video,
taken during the later part of project operations, did not show any
evidence of biological growth or crustations due to chemical reactions.
The migration of water within the basin subsequent to injection is a
factor that is of great interest to the project participants and local
landowners. However, due to monetary limitations, the evaluation of
'
the long-term movement of water was beyond the scope of this test
program.
The basic conclusions drawn from the Beckman Test UE Project are as
follows:
'
• Direct recharge by injection of the MRA water is possible.
Pt nIc anFinaIRnt6.doC II F30VLE
• During injection, a drawup or mounding of the local groundwater
level was experienced. However, this mounding dissipated within
minutes after injection was ceased. This indicates that the aquifer
readily accepted the injection water.
• Wells with a capacity of 1,000 gpm in extraction and 500 gpm or
more in injection appear to be feasible provided the well is
properly designed and the aquifer is similar to that used for this
Project.
• The plugging of the formation as a result of turbidity in the water
appears to follow a pattern that can be mathematically simulated.
• Injection wells can provide for a quick turnaround from injection
to extraction with minimal effort if the injection/extraction well is
properly designed. The well should be designed so that the
injection water is introduced into the well casing below the pump
bowls. Tubes mounted on the exterior of the casing should be used
to convey the injection water from the ground surface to the point
of injection.
• Initial indications are that the injected water can be extracted with
little degradation in water quality.
• Additional testing is necessary over a longer period of time to
confirm extraction characteristics and direction and rate of
movement of the injected water in the formation.

2. Number of surveys necessary to complete is 5% of the baseline number of housing units in 2001. 15%
of single-family units and 15% of multi -family units will be surveyed within 10 years of the date
implementation is to commence. Surveys will be conducted according to the following schedule: 1.5%
by end of the first reporting period, 3.6% by end of second reporting period, 6.3% by end of third
reporting period, 9.6% by end of fourth reporting period, and 15% by end of the fifth reporting period.
MOO, page 16 and page 17 Section Ed. California legislation requires that plumbing fixtures manufactured,
sold or installed alter early 1992 be low -water -use fixtures. Therefore, the greatest water savings can be
achieved in pre -1992 homes.
3. Single-family water usage = 450 gpd/unit (59% is outdoor use)
Single-family water usage was calculated based on estimated single family water use and single-family
households. The average monthly indoor water use is assumed to be equivalent to the average of 90
percent of the total water used in the lowest water use month in 1991, 1994, 1997, 1998, and 1999.
Outdoor water is calculated as the difference between annual total use and the assumed annual indoor
water use.
4. Multi -family water usage = 200 gpd/unit (27% is outdoor use)
Multi -family water usage was calculated based on historical multi -family water use and multi -family
households. The average monthly indoor water use is assumed to be equivalent to the average of 90
percent of the total water used in the lowest water use month in 1991, 1994, 1997, 1998, and 1999.
Outdoor water is calculated as the difference between annual total use and the assumed annual indoor
water use.
5. Water savings from indoor leak detection, not including toilet leaks= 0.5 gpd per residence
A & N Technical Services report (2000, page 2-20) (12.4 gpd per household repair, • 4 percent of households
audited have leaks).
6. Water surveys decrease outdoor water use by 10%
MOU estimate is 10% (page 17).
7. Each water survey costs $50
It is assumed that this BMP is done in conjunction with BMP 2.
8. The life span of a water survey is four years.
A & N Technical Services report (2000, page 2-20) gives life spans for various components of a water
survey. Four years was selected as a reasonable average value based on that information.
9. Water savings from indoor plumbing retrofits are tracked under BMP 2. Only water savings from a
decrease in outdoor water use and water savings from indoor leak detection are tracked in BMP 1 to
avoid double counting of water savings.

BMP 4 - Metering With Commodity Rates for all New Connections and Retrofit of Existing
Connections
Description: Install water meters at all connections.
Assumptions:
CASE 1: Installation of meters and meter boxes.
CASE 2: Installation of meters only.
1. Meters will be installed at all of pre -1992 residences within 10 years and all post 1992 connections
within 2 years.
The MOU (page 23) requires 100% of existing unmetered accounts to be metered within 10 years of
implementation date. As of January 1992, Califomia law requires all new services to include water meter
installation.
2. Weighted water usage per connection = 450 gpd/connection.
Weighted water usuage per connection is calculated based on 14,755 single family units, 648 multi -family
connections at 2000 gpd/connection, and 315 commerciaUinstitutional connections.
3. Metering will reduce water usage by 20%.
MOU, page 24.
4. Meter costs an average of $620 each, including meter, box, and overhead.
Cost estimate based on information obtained during a meter study for the City of Fresno (Brown and
Caldwell, 1992).
5. Installation of only a meter costs $100 each.
The City of Lodi has installed meter boxes on connections occurring after 1992. Connections occurring after
1992 will only cost an additional $100 to completely meter.
6. It will cost an average of $18/year to read and maintain one meter.
Cost estimate based on information obtained during a meter study for the City of Fresno (Brown and
Caldwell, 1992).
7. The life span of water meters is 20 years.
Public Utilities Commission Order 103 gives a 20 year life span for smaller than one -inch meters and 15 .
years for one -inch meters. It is assumed meters being installed are smaller than one -inch. This analysis
does not include replacement of meters.

BMP 5 — Large Landscape Conservation Programs and Incentives
Description: Conduct water surveys for accounts with large landscaped areas including schools,
cemeteries, parks, and civic centers. Provide recommendations for water conservation.
Assumptions:
1. Eto-based water use budgets will be developed for 90 percent of the CII accounts with dedicated
irrigation meters by the end of the second reporting period (22.5 percent per year for four years).
MOU (Page 27, Section C. a.)
2. Water surveys will be offered to 20 percent of the CII accounts with mixed use or no meters every
reporting period (10 percent per year).
MOU (Page 27, Section C.b.)
3. Irrigation water use surveys will be completed for 15 percent of CII accounts with mixed use or no
meters within 10 years of the date implementation was to commence. An agency will be considered on
track if the percent of CII accounts with mixed use or no meters receiving landscape water use equals
or exceeds the following: 1.5% by end of the first reporting period, 3.6% by end of second reporting
period, 6.3% b end of third reporting period, 9.6% by end of fourth reporting period, and 13.5 percent
by end of the 9" year. 15% must be reached by the end of the fifth reporting period.
MOU (Page 28, Section Ed.)
4. There are 26 dedicated landscape accounts and 1,324 CII mixed use accounts.
This is based on data provided by the City of Lodi, Public Water System Statistics, 1999 (Submitted March
2000).
5. Dedicated landscape accounts are an average size of 2 acres.
This is based on professional judgement.
6. CII mixed use account landscape areas are assumed to bean average of 0.5 acre in size.
This is based on professional judgement.
7. Water use prior to the survey is 5.1 ft per year.
Irrigation allocation is equal to 100 percent of local evapotranspiration (ETo), and the MOU estimates that
surveys will reduce water usage by 15 percent. The local ETo was determined (53 irtlyear based on
California Irrigation Management Information System data) and multiplied by 1.15 to obtain 61 inches (5.1 h)
per year for current water use. (Most conservative approach for economic analysis)
8. Surveys will reduce water usage by 15%.
MOU, page 29.
9. The life span of the large landscape water surveys is four years.
A & N Technical Services report (2000) gives a life span of four years for tun` audits (page 2-20). It is
assumed that water surveys for large landscapes will have a similar life span.
10. Each survey will cost $250 per acre.
This estimate is based on information presented in Cal Poly's 1988189 annual report on their landscape
water management program. The estimate includes labor, administration, evaluation and overhead.

BMP 6 — High -Efficiency Washing Machine Rebate Programs
Description: Provide rebates to single-family residences for high -efficiency washing machines.
Assumptions
1. Each rebate will cost $75.
The MOU does not require implementation of this BMP if the maximum cost-effective rebate is less than $50
(MOU, page 31). A $50 rebate plus an additional $25 per rebate for program administration and overhead
was assumed.
2. Each high efficiency washing machine will reduce water usage by 5,100 gallons per year.
MOU, page 32.
3. Rebates will be accepted by one percent of single-family residences per year for 20 years.
Estimate based on professional judgement.
4. The life span of a high efficiency washing machine is 12 years.

BMP 9 — Conservation Programs for Commercial, Industrial, and Institutional (CII) Accounts
Description: Implement a program to conduct water -use surveys and customer incentives programs for CII
customers.
Assumptions:
1. Water -use surveys will be conducted at 10% of CII accounts within 10 years of the date implementation
is to commence. Surveys will be conducted according to the following schedule: 0.5% of the total
number of surveys required by the end of the first reporting period, 2.4% by end of second reporting
period, 4.2% by end of third reporting period, 6.4% by end of fourth reporting period, and 10% by the
end of the fifth reporting period. Those customers will also be included in an incentives program.
MOU, page 37 and page 40, Section E.b.3
Ultra -low -flush toilets (ULFT) in CII establishments will be replaced to produce water savings over a 10
year implementation period equal to 15 percent of total water savings potential as determined in Table
E-2. Economic Analysis Worksheets.
MOU, BMP 9, A. (b)ii.
Given the choice to implement BMP 9 A (c) or (d), we have selected to implement (c), CII Water Use
Survey and Customer Incentives program.
MOU BMP 9, A.(c)
4. The life span of a water survey is four years.
It was assumed that the life span for a CII water survey is the same as the life span for a residential survey.
A & N Technical Services report (2000, page 2-20) gives life spans for various components of a residential
water survey: Four years was selected as a reasonable average value based on that information.
5. The average annual water savings resulting from a commercial and institutional water survey is 0.83
acre-feet per account.
A & N Technical Services report (2000, page 2-35) gives average annual water savings for three types of
surveys; "analyst surveys", consultant surveys" and "water efficiency studies" Analyst surveys are
conducted by non -engineers, consultant surveys are conducted by engineers for sites that have process
water, and water efficiency studies are conducted at major industrial facilities that use very large quantities
of water. For purposes of this economic analysis, it was assumed that only analyst surveys will be
conducted for commercial and institutional account surveys. Values for water savings in the A& N report
represent the maximum potential water savings that could occur if a customer were to implement every
possible water conservation measure. Experience has shown that approximately 25% of the maximum
potential water savings is actually realized, which is what was assumed (personal communication with John
Sweeten, Metropolitan Water District, 5-9-00.)
6. The average annual water savings resulting from an industrial water survey is 2.1 acre-feet per account.
A & N Technical Services report (2000, page 2-35) gives average annual water savings for three types of
surveys, `analyst surveys", "consultant surveys" and "water efficiency studies" Analyst surveys are
conducted by non -engineers, consultant surveys are conducted by engineers for sites that have process
water, and water efficiency studies are conducted at major industrial facilities that use very large quantities
of water. For purposes of this economic analysis, it was assumed that only consultant surveys will be
conducted for industrial account surveys. Values for water savings in the A& N report represent the
maximum potential water savings that could occur if a customer were to implement every possible water
conservation measure. Experience has shown that approximately 25% of the maximum potential water
savings is actually realized, which is what was assumed (personal communication with John Sweeten,
Metropolitan Water District 5-9-00.)
7. Each analyst survey (for commercial and institutional accounts) will cost an average of $680 and each
consultant survey (for industrial accounts) will cost an average of $1,680. These costs include the cost

BMP 14 — Residential ULFT Replacement Programs
Description: Implement a program to replace existing high -water -using toilets with ultra -low -flush toilets
(ULFT) in single- and multi -family residences.
Assumptions:
1. There are an average of 3.3 people per single-family residence and 2.4 people per multi -family
residence.
Lodi has an average of 2.6 people per household (California Department of Finance Report E-5, Table 2
"City/County Population and Housing Estimates" January 1, 2000). Because useful data quantifying single-
family and multi -family household sizes in this CSA are unavailable, it is assumed that a ratio of multi -family
to single-family household sizes is 0.7.
2. There are an average of 1.8 toilets per single-family residence and 1.5 toilets per multi -family residence.
An average of 1.7 toilets per unit was calculated using 1990 census data concerning the number of
bedrooms per housing unit. Based on professional judgement, it was assumed a one bedroom unit has 1
toilet, a two bedroom unit has 1.5 toilets, a three bedroom unit has 2 toilets, a four bedroom unit has 2.5
toilets and a five bedroom unit has 3 toilets. Because multi -family units tend to have fewer toilets on
average than single-family units, it was assumed 1.5 toilets per multi -family residence and calculated that
the single-family units would need to have 1.8 toilets per unit to achieve an overall average of 1.7 toilets per
dwelling unit.
3. Water savings from ULFTs are 37 gpd/unit for single-family residences and 51.7 gpd/unit for multi-
family residences.
MOU, Exhibit 6, Table 1 and Table 2.
4. Homes constructed after 1991 already have ULFTs.
As of January 1992, California legislation requires that ULFTs be installed in all newly constructed homes.
5. The life span of the new ULFTs is 20 years.
MOU, page 70.
6. Natural toilet replacement rate is 4% per year.
MOU, page 70.
7. Average resale rate for single-family units in San Joaquin County is 3.6%
Assumption based on the 1996 single-family average resale rate for San Joaquin County. This rate was
obtained from the CUWCC Website, WWW.CUWCC.ORG, November2000.
8. Average resale rate for multi -family units in San Joaquin County is 3.1%
Assumption based on the 1998 multi -family average resale rate for San Joaquin County. This rate was
obtained from the CUWCC Website, WWW. CUWCC. ORG, November 2000.
9. The cost of toilets, advertising, administration, overhead, and toilet recycling is $126 per ULFT. The
cost does not include installation, which will be covered by the customer.

This document is a Water Shortage Contingency Plan for the City of Lodi water system (City). The
purpose of this contingency plan is to provide a plan of action to be followed at the various stages
of a water shortage.
SECTION 1. WORST CASE SCENARIO
California Water Code section 10632 (b) requires an estimate of the minimum annual water supply
availability during each of the next three water years based on the driest three-year historic sequence
for the agency's water supply. The City of Lodi's water supply is 100% groundwater. Although
regional groundwater levels have been dropping, no short-term water supply problems are
anticipated in the next three years.
The available water supply for the City is the water production well capacity of 33,695 gallons per
minute (Year 2000) or 48.5 million gallons per day (mgd). The annual average well production for
1999 was 14.81 mgd. Loss of water supply capacity could occur due to mechanical problems with
wells, pumps, motors, etc. of the distribution system. Preventative maintenance programs aid in
minimizing the occurrence of mechanical failures. In addition, a water supply capacity loss may be
caused by a change in water quality due to well contamination. Worst case water supply projections
are not included in this section because distribution system mechanical failures and well
contamination events are not expected and the capacity loss associated with each problem is difficult
to quantify.
SECTION 2. WATER SUPPLY SHORTAGE STAGES AND CONDITIONS
This section describes the stages of action to be undertaken in response to water supply shortages.
Included is an outline of specific water supply conditions that are applicable to each stage.
Per California Water Code section 10632 (a), the City has developed five stages of action to be
undertaken in response to water supply shortages, including up to a 50 percent reduction in water
supply and an outline of specific water supply conditions which are applicable to each stage.
The five stages of action are defined below. The stage determination and public declaration during a
water supply shortage will be made by the Public Works Director.
Stage I — Normal Conditions: The City is able to meet all immediate needs of the customers.
Stage II — Water Alert: A 5% or greater reduction in water usage is required for the City to meet
the immediate needs of its customers.
Stage III — Water Warning: A 15% or greater reduction in water usage is required for the City to
meet the immediate needs of its customers.
Stage IV — Water Crisis: A 30% or greater reduction in water usage is required for the City to meet
the immediate needs of its customers.
PA20000120650 Lodi UWMP\WMP15-01 Final Draft Report\AppendicesWppendix FTinal AppdxF 6-01.doc 06/11/01
Stage V -Water Emergency: A 50% or greater reduction in water usage is required for the City to
meet the immediate needs of its customers.
The water stages are described in detail in Section 3.
SECTION 3. MANDATORY PROHIBITIONS, CONSUMPTION REDUCTION
METHODS, AND PENALTIES
The prohibitions, consumption reduction methods, and penalties and charges for each of the five
water supply stages are included in this section as required in California Water Code sections 10632
(d), 10632 (e), and 10632 (f), respectively.
Stage I. Normal Water Conditions
All requirements of the City's Water Conservation Ordinance, Lodi Municipal Code, Section
13.08.290, shall be in effect for Stage 1 as normal conditions. Lodi's water conservation program
consists mainly of outdoor watering restrictions enforced by water conservation patrol staff, public
education through local fairs, bill inserts, and newspaper articles, and an in -school education
program. The waste of water is prohibited and defined in the Water Conservation Ordinance as:
• Failure to repair a controllable leak of water.
• Watering of lawns, flowerbeds, parking areas, tennis courts, patios, streets, or other exterior
paved areas on days or times other than those outlined in Section 13.08.240 of the Water
Conservation Ordinance as:
A. Watering Days:
1. Premises having odd numbered street addresses on Wednesday, Friday, and
Sunday.
2. Premises having even numbered street addresses on Tuesday, Thursday, and
Saturday.
B. Watering Hours: Any hour except that between May 1 and September 30 (inclusive)
of each year watering between the hours of 10 a.m. and 6 p.m. is prohibited.
• Washing of sidewalks, driveways, parking areas, tennis courts, patios, streets, or other
exterior paved areas or buildings except when required to remove any spillage of substances
that may be a danger to public health or safety.
Washing with water any motor vehicles, trailers, or movable equipment other than with a
bucket and rinsing the vehicle or equipment by use of a hose for not more than three
minutes.
• Use of a hose without a positive shut off nozzle.
• The excess watering of any area so that water flows into a gutter or any drainage area for a
period exceeding three minutes.
• The unnecessary running of water in any residential, commercial, or industrial establishment
onto the floor, pavement, ground or into any drain or drainage area, with any equipment or
in any way for more than three minutes.
• Overwatering of lawns or landscapes from November 1 through February 28, or during or
immediately following a rain.
PA20000t20650 Lodi UWMPIWMP\5-01 Final Draft Report\AppendicesWppendix BMW AppdxF 6-Ol.doc 06/11/01
Enforcement procedures and penalties for water wasting as defined in Section 13.08.250 of Lodi's
Water Conservation Ordinance include:
• First Water Waste: Notification of water waste to the person at the premises of water waste

No potable water from the City's system shall be used for construction purposes such as
dust control, compaction, or trench jetting.
Large industrial users, for example canneries and other food manufacturers, be required to
reduce or cease all water use.
SECTION 4. REDUCTION MEASURING MECHANISM
California Water Code sections 10632 (i) requires the water supplier to develop a mechanism for
determining actual reductions in water use in the course of carrying out the urban water supply
shortage contingency analysis.
The City of Lodi's residential customers are not metered and approximately 72 percent of non-
residential customers are metered. Reductions in water use from these non-residential customers
can be measured by individual water meters. Exceptionally high usage will be identified by the City,
and these accounts will be investigated for potential water loss or abuse problems. Water well
production figures are recorded daily. Totals are reported monthly and are incorporated into water
supply reports.
During all stages of water shortages, daily production figures are reported to and monitored by the
appropriate City Public Works employee. The City may elect to read non-residential customer
meters on a more frequent basis.
SECTION 5. PREPARATION FOR CATASTROPHIC WATER SUPPLY
INTERRUPTION
The Water Code section 10632 (c) requires actions to be undertaken by the water supplier to prepare
for, and implement during a catastrophic interruption of water supplies. A catastrophic event that
constitutes a proclamation of a water shortage would be any event, either natural or manmade, that
causes a severe shortage of water, synonymous with or with greater severity than the Stage III or
Stage IV water supply shortage conditions.
The City of Lodi maintains a sound preventative maintenance program of their distribution system.
Auxiliary generators are available and improvements to water facilities are made to minimize loss of
these facilities during an earthquake or any disaster causing an electric power outage.
Action items that may be pursued in preparing for and responding to a catastrophic water supply
interruption could include:
• Increase existing water_%L4& rag -'St0(-u��
• Obtain additional water supplies.
• Determine where funding for additional water supplies will come from.
• Contact and coordinate with other agencies.
• Create an Emergency Response Team/ Coordinator.
• Create a catastrophe preparedness plan.
• Put employees/contractors on-call.
• Develop methods to communicate with the public.
• Develop methods to prepare for water quality interruptions.

SECTION 6. ANALYSIS OF REVENUE AND EXPENDITURE IMPACTS
Section 10632 (g) of the California Water Code requires an analysis of the impacts of each of the
actions taken for conservation and water restriction on the revenues and expenditures of the water
supplier. Approximately 73% of the City's water was supplied to non -metered residential and
industrial/commercial customers in 1999. Because the City of Lodi charges a flat rate to all of its
residential customers and unmetered non-residential customers, revenue impacts of decreasing
supply and consumer use will be minimal.
The majority of the City's water customers are charged with a flat rate. A reduction in the use of
water may have a corresponding reduction in the expenditures by the City for the treatment and
distribution of the water supply. Any of the aforementioned reductions in expenditures could be
offset by increased costs for personnel time during the emergency, notification actions, emergency
equipment rental or purchase, emergency generator usage, etc.
Because no substantial financial impacts are anticipated on the revenues and expenditures of the
City, no measures to overcome impacts are included.
SECTION 7. DRAFT WATER SHORTAGE CONTINGENCY RESOLUTION
Section 10632 (h) of the California Water Code requires the inclusion of a draft water shortage
contingency resolution. In the event of a water shortage emergency, the following is a draft water
shortage contingency resolution to be passed by the Lodi City Council. The draft below gives the
City Council's support to the Public Works Director in taking emergency actions as currently
authorized in Lodi Municipal Code, Chapter 13.08, Article III, Section 13.08.290, "Emergency
Water Conservation".
