Public Participation
Law
10642. Each urban water supplier shall encourage the active involvement of
diverse social, cultural, and economic elements of the population within the
service area prior to. and during the preparation of the plan. Prior to adopting a
plan, the urban water supplier shall make the plan available for public inspection
and shall hold a public hearing thereon. Prior to the hearing, notice of the time
and place of hearing shall be published ... After the hearing, the plan shall be
adopted as prepared or as modified after the hearing.
Public Participation
The City of Vernon (City) has encouraged community participation in its urban water management
planning efforts through its City Council (Council). The Council, which is comprised of elected community
representation, has been actively involved since the first plan was developed in 1995. Additionally, city
council meetings are held twice a month, giving the community at large an opportunity to provide input and
participation in the urban water management planning effort.
Notices of the public hearings pertaining to this Urban Water Management Plan were posted in three (3) of
the most public places in the City: the northwest corner of 38th St and Santa Fe Ave; the northeast corner
of Leonis Blvd and Pacific Blvd; and on the bulletin board in the lobby of City Hall of the City of Vernon,
located at 4305 Santa Fe Avenue. In addition, notification was published in the Metropolitan News-
Enterprise, which was determined to be a newspaper of general circulation nearest to the City most
appropriate for this purpose.
In addition, specific groups and individuals that participated in the development of this plan are listed in
Appendix A.
Plan Adoption
The City of Vernon prepared this update of its Urban Water Management Plan during the fourth quarter of
2005. The updated plan was adopted by the Council in December 2005 and submitted to the California
Department of Water Resources within 30 days of Council approval by December 31, 2005. Attached is
the cover letter addressed to the Department of Water Resources and, as Appendix B, are copies of the
signed Resolution. of Plan Adoption. This plan includes all information necessary to meet the
requirements of California Water Code Division 6, Part 2.6 (Urban Water Management Planning).

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
Agency Coordination
Law
10620 (d) (2) Each urban water supplier shall coordinate the preparation of its
plan with other appropriate agencies in the area, including other water suppliers
that share a common source, water management agencies, and relevant public
agencies, to the extent practicable.
Coordination Within the City
The City's Director of Community Services and Water met and coordinated the development of this plan
with assistance from the City Council, Deputy Director and Operations Supervisor.
The City plans future water supplies through active participation with the Central Basin Municipal Water
District (CBMWD). As a member agency of CBMWD, the City, through Council and Staff interaction,
coordinates the projections and ability of the CBMWD to provide an adequate imported water supply. For
detailed information on how the demands of the City will be met, please see the 2005 Urban Water
Management Plan, submitted by CBMWD. However, in the event of a declared water shortage, the City
has conservation policies and action plans in place (Appendix C - City Ordinance 955).
The City, in preparation for completing this report enlisted several key staff to attend Urban Water
Management Plan meetings, which provided the opportunity for extra intra-City coordination. These
meetings were initiated by the Director of Community Services and Water, and attended by the Deputy
Director and Water Operation Supervisor.
Interagency Coordination
The City of Vemon is one of 27 member retail agehcies of the CBMWD. Member agency status entitles
the City to directly purchase water for its needs from the CBMWD on a wholesale basis. Currently, the City
has no existing water transfers with any neighboring water retail agency. The City therefore coordinated
the development of this plan with CBMWD. Table 1 summarizes the efforts that the City has taken to
include various agencies and its citizens in the planning process.

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
Supplier Service Area
Law
10631. A plan shall be adopted in accordance with this chapter and shall do all
of the following:
10631. (a) Describe the service area of the supplier, including current and
projected population, climate, and other demographic factors affecting the
supplier's water management planning. The projected population estimates shall
be based upon data from the state, regional, or local service agency population
projections within the service area of the urban water supplier and shall be in
five-year increments to 20 years or as far as data is available.
Climate
Vernon lies within the South Coast Air Basin, which has semi-arid Mediterranean climate. Summers are
mild and dry, with temperatures rarely exceeding 90 degrees Fahrenheit. The winters are cool, with an
average low temperature of approximately 50 degrees Fahrenheit. Over the past 43 years, the City has
experienced an average of 14 inches of precipitation, with an average annual temperature of 64 degrees
Fahrenheit. Deviation from the average annual precipitation was experienced last year due to the large
storm event experienced in Los Angeles County. Total rainfall for last year was 31.3 inches.
Other Demographic Factors
The City of Vernon is located in the Los Angeles-Long Beach metro area, approximately 15 miles
Northeast of the Los Angeles International Airport at a latitude and longitude of 34.003N and -118.229W
respectively. The City occupies an area of about 5.0 square miles (3,200 acres).
The following excerpt information was taken from City of Vernon, prepared by Pete Moruzzi for the Los
Angeles Conservancy tour publication Cruising Industrial Los Angeles, October 1997:
Vernon was founded and incorporated in 1905 by James J. and Thomas J. Furlong, both ranchers, and
John B. Leonis, rancher and merchant. John Leonis was of Basque origin, coming to Southern California
in 1880 to work for his uncle Miguel Leonis whose original 1862 adobe dwelling in Calabasas was
designated City of Los Angeles Cultural-Historic Monument #1. John Leonis established his own ranch on
unincorporated county land southeast of Downtown. Recognizing the significance of the three major
railroads running through the area, he convinced railroad executives to run spur tracks off the main lines
and incorporated the adjacent three miles as an "exclusively industrial" city named atter a dirt road,
~ernon Avenue, crossing its center.
While waiting for industry to develop in the area, the founders of the city thought of marketing Vernon as a
"Sporting Town." In 1907, on land leased from Leonis, Entrepreneur Jack Doyle opened what was billed
as the "longest bar in the world." It had 37 bartenders, 37 cash registers and a sign advising "if your
children need shoes, don't buy booze." Next door Doyle opened the Vernon Avenue Arena where 20-
round world championship fights were held starting in 1908. Soon after, the Pacific Coast (baseball)
League built a ballpark with its left field corner abutting Doyle's bar and its own entrance into the park. The
Vernon Tigers won three Consecutive league pennants. Last call for Doyle's Bar was June 30, 1919 when
over 1,000 people swilled their last pre-Prohibition drink. The chamber of commerce now sits atop Doyle's
onetime empire.
After 1919, Vernon went back to being exclusively industrial. Two giant stockyards, one owned by John
Leonis, opened with meat packing quickly becoming Vernon's signature industry. Twenty-seven
slaughterhouses lined Vernon Avenue from Soto Street to Downey Road until the late 1960s. Said one
longtime Boyle Heights Resident, "we could smell Vernon in the evenings at our home."

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
In the 1920s and 30s, heavy industries such as steel (U.S. and Bethlehem), aluminum (Alcoa), glass
(Owens), can~making (American Can) and automobile production (Studebaker) grew in the City. The
1940s and 50s added aerospace contractors (Norris Industries), box and paper manufacturers, drug
companies (Brunswig), and food processors (General Mills, Kal Kan). Giant meat packers (Farmer John
and Swift) continued to grow. A strong, unionized labor force meant excellent middle class incomes for
thousands of families.
In 1932, the City differed with Southern California Edison over industrial rates for Electricity, John leon is
orchestrated a Vernon bond measure to authorize the construction of the city's own light & Power plant,
which is still operational today. low-cost power and water, along with low taxes, attracted businesses to
Vernon. later, economical factors including, the free flow of capital and labor across borders had, by
1980, utterly transformed Vernon's industrial face.
The City's signature businesses, the slaughterhouses, relocated. lower-cost producers in the East and
Midwest reduced meat packing plants from 27 to today's two. Bethlehem and US Steel competed
unsuccessfully with European and Asian suppliers. Studebaker and American Can are closed. Defense
cutbacks negatively impacted Alcoa and Norris industries. Today smaller industrial/commercial
establishments including fashion design, garment-making, film production, electronics, and waste
recycling are characteristic of the business community in Vernon.
The Vernon water distribution system consists of 250,000 lineal feet of pipe, nine wells, seven ground
level reservoirs, one elevated tank and a below ground reservoir, The total storage capacity is 16.75
million gallons. In addition, Vernon has a direct interconnection to the CBMWD. The CBMWD connection
provides both a supplemental water source and an emergency supply in the event of a major power
outage.
As it is predominantly a commercial and industrial city, the City of Vernon has very few permanent
residents, with no substantial population increases anticipated in the future. Table 2 shows the population
total. for the City from 2005, with projections to 2025, assuming the same 0.7% annual increase
experienced between 2000 and 2003. Population numbers for 2000 (91 people) were obtained from the
2000 census, U.S. Census Bureau, while 2003 numbers (93 people) were obtained from a periodical
database on the internet at www.epodunk.com.

Past Drought, Water Demand, and Conservation Information
The Southern California region experienced a prolonged drought between 1987 and 1992 that caused
severe water shortages throughout the state. This resulted in a shortfall in surface water supply, causing
many areas of the state to adopt regulations limiting water consumption. In response to this condition, the
City of Vernon adopted Ordinance No. 995 providing for water conservation (Appendix C), This Ordinance
established conservation measures for Phase I, Phase II and Phase III water shortages. These shortages
equate to maximum water supply deficiencies of 20%, 30% and greater, respectively. Through the
implementation of this Ordinance, and the pumping of the City's groundwater allocation, the City of Vernon
was able to meet water demands during these drought years.
Since 2000, new water demand has decreased by a rate of about 1-2% per year (Table 5), due in part to
more efficient commercial and industrial usage, overall conservation efforts and a general slow-down in
the region's economy. All of the City's service area is built-out, with almost no new accounts anticipated in

the future. Consequently, the anticipated growth rate is expected to remain relatively low over the next 20
years.
The City's service area is comprised predominately of commercial and industrial users. Currently the City's
potable water supplies are distributed among the following sectors: 94% to commercial and industrial
accounts; 0.2% to institutional accounts and 0.1 % to residential accounts. The commercial and industrial
sectors currently comprise 97% of the City's potable water connections, while institutional and residential
connections comprise only 2% and 1 % each. The City has no agricultural or landscaping users.
As part of an effort toward local sustainability and water conservation, the City has begun purchasing
1,438 AFY of recycled water from the Central Basin Municipal Water District (CBMWD). In order to provide
this service, the City has constructed almost 10,000 linear feet of recycled water pipeline. The City
anticipates purchasing an additional6,834AFY by 2010, and an additional 6,666 AFY by 2015.

increments [to 20 years or as far as data is available.]
Water Supply Sources
The City of Vernon currently has three sources of water: groundwater, recycled water and purchased
water from the Central Basin Municipal Water District (CBMWD). Based upon the City's 2005 annual
usage, adjudicated groundwater rights, recycled water agreements and base allocation from CBMWD, the
City experiences a 0.6 MGD {698 AFY} water supply surplus. All of these sources can supply additional
water as the need arises.

Groundwater
The City of Vernon has adjudicated groundwater basin rights of 8,039 acre-feet per year {AFY}. For 2005,
it is anticipated that the City will extract 7,865 AFY from nine {9} wells. For these wells, the average static
levels range between 175 to 250 feet, the average pumping levels range from 275 to 350 feet, with an
average total depth of 1,480 ft. In 1959, the State Legislature enacted the Water Replenishment Act,
enabling the formation of the "Central and West Basin Water Replenishment Acf' {now referred to as the
Water Replenishment District of Southern California or 'WRD"} to be the permanent agency in charge of
replenishing both Basins. The State Legislature has vested in WRD the statutory responsibility to manage,

regulate, replenish and protect the quality of groundwater supplies within it boundaries, of which the City of
Vernon is included.
With additional groundwater leases and carryover from previous years, the actual allowable extraction can
exceed 8,039 AFY. As with all retailers in the CBMWD, the City can carryover 20 percent of its unused
allocation to the next fiscal year. A recent analysis of the Department of Water Resources Water Master
Records indicate that the potential to lease additional rights within the basin is realistically limited to about
3,500 AFY.
During a declared water shortage, the Watermaster (Central Basin) may allow the City to over pump 20
percent of its water rights; however, in doing so it must decrease its allocation by 20 percent the following
fiscal year. With this arrangement, the City can sustain itself during a declared water shortage. The City
manages its supply so that when additional water is needed, due to the possibility of a shortfall in imported
supply, these groundwater rights can be exercised.
Imported Water
The City currently purchases treated water from the Central Basin Municipal Water District (CBMWD).
According to the 2003 Purchase Agreement for Imported Water to be Provided by Central Basin Municipal
Water District (2003 CBMWD Agreement), the City has a base allocation of 3,350 AFY, including a Tier 1
annual maximum of 3,015 AFY (90% of base allocation). Additional water can be purchased from
CBMWD; however, it will need to be purchased at the Tier 2 water rate. While Tier 2 imported water is
available in unlimited quantities during normal years; Tier 2 water supply could be reduced in the event of
a drought situation.
Recycled Water
Recycled water is one of the cornerstones of Central Basin's efforts to augment local supplies and reduce
dependence on imported water. Since the planning and construction of Central Basin's recycled water
system in the early 1990's, Central Basin has become a leader in producing and marketing recycled water.
This new supply can assist the City of Vernon in meeting the demand for non-potable applications such as
commercial and industrial processes. It is only limited by the infrastructure needed to deliver this source to
the City of Vernon.
Currently, the City purchases 1,438 AFY of recycled water from CBMWD in order to provide service for the
on-site cooling towers of a recently constructed power plant (Malburg Generation Station). In order to
provide this service, the City of Vernon has constructed almost 10,000 linear feet of recycled water
pipeline, capable of supplying recycled water from CBMWD. The City of Vernon has entered into an
agreement with CBMWD to provide recycled water to this power plant. In the event that the recycled water
supply is interrupted, this agreement stipulates that CBMWD will increase the supply of Tier 2 imported
potable water to compensate for any disruption of recycled water, regardless of the drought conditions in
Central Basin.
Recent market assessments, conducted by the City, have identified an additional power plant with on-site
cooling towers, anticipated to begin operations within the next five years. Phase I of this power plant,
anticipated to be completed prior to 2010, will have an annual recycled water demand of 6,834 AFY.
Phase II, anticipated to be completed by 2015, will require an additional 6,666 AFY of recycled water. An
agreement between the City of Vernon and CBMWD is currently being negotiated to provide recycled
water to this proposed power plant. Similar to the previous agreement, CBMWD will insure that if the
recycled water supply is interrupted, CBMWD will increase the supply of Tier 2 imported water to the City
in order to compensate for the disruption of recycled water, regardless of the drought conditions in Central
Basin. Furthermore, the City has begun working with CBMWD on the Southeast Water Reliability Project
which will provide the necessary infrastructure to provide this additional recycled water through a
proposed 42" diameter, looped pipeline.

which includes each of the following elements which are within the authority of
the urban water supplier:
10632 (b) An estimate of the minimum water supply available during each of the
next
three-water years based on the driest three-year historic sequence for the
agency's water supply.
Reliability
The costs of demand management or supply augmentation options to reduce the frequency and severity
of shortages are now high enough that city planners must look more carefully at the costs of unreliability to
make the best possible estimate of the net benefit of taking specific actions, hence the term "reliability
planning." Reliability is a measure of a water service system's expected success in managing water
shortages.
To plan for long-term water supply reliability, planners examine an increasingly wide array of supply
augmentation and demand reduction options to determine the best courses of action for meeting water
service needs. Such options are generally evaluated using the water service reliability planning approach.
In addition to climate, other factors that can cause water supply shortages are earthquakes, chemical
spills, and energy outages at treatment and pumping facilities. City Planners include the probability of
catastrophic outages when using the reliability planning approach.
Reliability planning requires information about: (1) the expected frequency and severity of shortages; (2)
how additional water management measures are likely to affect the frequency and severity of shortages;
(3) how available contingency measures can reduce the impact of shortages when they occur.
The City of Vernon is one of 27 member retail agencies of the CBMWD. Member agency status entitles
the City to directly purchase water for its needs from the CBMWD on a wholesale basis. The City. of

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
Vernon looks to theCBMWD to insure, to the best of its ability, that adequate amounts of imported water
will be available to satisfy future water requirements.
Since joining the Metropolitan Water District of Southem California (MWD) in 1954, CBMWD relies on
approximately 90,600 AFY of imported water from the State Water Project and the Colorado River to meet
the District's retail and replenishment demands. To meet the challenges of the supply shortages on the
State and Colorado Aqueducts due to increases in population and growing State- and Federal regulatory
requirements, MWD's Board of Directors called for the development of an Integrated Water Resource Plan
in 1996 (IRP). In 2003, MWD completed its first update to the IRP, which included revised projected
demands and an updated resource supply mix. Among the most significant findings from the update IRP
was the increase participation of local agencies in developing local supplies, as well as promoting savings
from conservation. The result of which revealed a greater source of local supply reliability than anticipated
among MWD member agencies. Overall, the 2003 IRP Update revealed a decrease in the region's
reliance on Colorado River and State Aqueduct supplies compared to the 1996 IRP, while continuing to
provide 100 percent reliability through the year 2025.
Along with MWD's reliability initiatives, CBMWD has also taken important steps over the past decade to
reduce the District's vulnerability to extended drought or other potential threats. CBMWD's investments in
recycled water to replace imported water for non-potable uses and the implementation of conservation
devices and education have resulted in more self-reliance. In addition, CBMWD has also adopted
Ordinance No. 1-91-16 requiring its member agencies to provide mandatory conservation plans in order to
minimize the effect of a shortage of. water supplies on their customers in case of a water shortage
emergency. This ordinance also imposed surcharges for excessive use of water by member agencies and
granted credits for conservation measures which reduce water use below the staged percentages set forth
therein.
In response to CBMWD's Ordinance No.1-91-16, the City of Vernon adopted Ordinance No. 955 (See
Appendix C), which enacted Article VI of Chapter 25 of the Code of the City of Vernon, 'Water
Conservation", containing Code Sections 25.100 through 25.111. Minimum requirements were outlined in
this Ordinance to protect the water supplies and to establish standards for reductions in the use of water in
the City of Vernon.
Frequency and Magnitude of Supply Deficiencies
During the 1987-92 drought, California went through a below average rainfall condition. This resulted in a
shortfall in water supply, causing many areas of the state to adopt regulations limiting water consumption.
In response to this condition, the City of Vernon adopted Ordinance No. 995 providing for water
conservation. This Ordinance established conservation measures for Phase I, Phase II and Phase III
water shortages. These shortages equate to maximum water supply deficiencies of 20%, 30% and
greater, respectively. Through the implementation of this Ordinance, and the pumping of the City's
groundwater allocation, the City of Vernon was able to meet water demands during these drought years.
Plans to Assure a Reliable Water Supply
The City's future supply projections assume uninterrupted service from CBMWD. The City has a base
allocation of 3,350 AFY from CBMWD, including a Tier 1 annual maximum of 3;015 AFY (90% of base
allocation). In the event of a short-term supply interruption, the City of Vernon is capable of pumping
additional groundwater to make up the difference. The probability of an extended shortage due to a natural
disaster or accident that damages both imported and local sources is low.

Three Year Minimum Water Supply
Based on data generated by the drought of 1987-1992, statistics indicate that the City's customers
accepted the need to enter into a conservation phase to address the water shortage. As the community
continues to become more water efficient, it may become more difficult for customers to reduce their water
use during water shortages (this is called "demand hardening"). Staff does not believe that City customers
are yet approaching demand hardening, because there are still large potential water efficiency
improvements in the commercial and industrial sectors. However, improved water use efficiency does
mean that water supply reserves must be larger and that water shortage responses must be made early to
prevent severe economic and environmental impacts.
The driest three-year historic sequence for the City's water supplies continues to be the 1990 to 1992
period. During both the 1990-91 and 1991-92, the City's historical production data indicates that total
supplies dropped to 88% of normal year production. Because shortages can have serious economic and
environmental impacts, the City will make every effort to limit water shortages to no more than 15%.
Under severe drought emergency conditions, the City would need to rely more heavily upon the
groundwater basin. This could be done for several years without serious impact other than the increased
pumping costs and future increased costs of extending the pumps or drilling new wells.
Recycled water demand will never exceed recycled water supply in the event of a shortage. It is not
expected that any potable water supply reductions would result in recycled water shortages. In the event
of a short-term recycled water shortage, existing and future agreements with CBMWD stipulate that
CBMWD will il'1crease the supply of Tier 2 imported potable water to compensate for any disruption of
recycled water, regardless of the drought conditions in Central Basin. In the event of a long-term recycled
water shortage, both the existing and proposed power plants will maintain enough on-site emergency
storage to "power down" and terminate operations until the recycled water shortage is over.

Water Quality Impacts on Reliability
Law
10634. The plan shall include information, to the extent practicable, relating to
the quality of existing sources of water available to the supplier over the same
five-year increments as described in subdivision (a) of Section 10631, and the
manner.in which water quality affects water management strategies and supply
reliability.
Water Quality Impact
Water quality is an important consideration because water that does not meet health standards is
effectively lost as a source of supply. The quality of surface water can be affected by salinity, point
sources (upstream discharges) and agricultural runoff, while groundwater supplies are threatened by
contamination from disposal and seepage of toxic chemicals. In a region such as southern California,
groundwater contamination can cause loss of significant supply and increase the demand of imported
water.
Imported Water
A major challenge to Metropolitan Water District (MWD) in ensuring high quality water to its member
agencies is the issue of salinity. Water from the Colorado River Aqueduct (CRA) generally contains high
levels of salinity. In 1999, MWD developed a Salinity Management Policy to address this issue. The main
objective of the policy is to achieve a salinity goal of 500 mg/L, which is done by blending CRA water with
lower salinity State Water Project (SWP) water. MWD is actively encouraging its member agencies to
develop local storage options to help mitigate the effect of a period of high salinity, as well as taking steps
to control salinity in its sources.
Groundwater
In the City of Vernon, groundwater quality has been impacted by a variety of chemical contaminants
including volatile organic compounds (VOCs), perchlorate, iron and manganese. All of these compounds
can have negative health impacts and all have maximum contaminant levels (MCLs) which have been set
by the Environmental Protection Agency (EPA). These substances comprise the constituents of concern
(COe) for groundwater in the region.
VOCs exceeding the MCL have been found at two well sites within the City of Vernon. The VOCs 1,2-
dichloroethane (1,2-DCA) and trichloroethylene (TCE) and the contaminant perchlorate have been
detected at significant concentrations at these sites within the City of Vernon. Perchlorate (CI04) has been
detected at levels ranging from non-detected (ND) to 18 IJglL. The State notification level (NL) for CI04 is
6 IJg/L. As a result of these high levels of VOCs, the City now operates only seven (7) of its nine (9)
groundwater wells.
Iron (Fe) and manganese (Mn) have been detected at all well sites in the City. At most sites, the
concentrations of these chemicals is well below the State Maximum Containment Levels. For iron and
manganese, the State MCL's are 300 IJg/L and 50 IJg/L respectively.

..
CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
-
Future changes in mandated MCl's may affect available groundwater supplies, however predicting these
changes is not included in this Urban Water Management Report. .
Implications for Water Management
Water quality can adversely affect water management by reducing available supply sources and reliability.
The City of Vernon has not been adversely affected from well closures, as even with only seven (7) out of
nine (9) wells in operation, the City still maintains adequate production capabilities to meet daily
requirements. However, with other wells offline, there is little system redundancy. Future well closures due
to water quality concerns would ultimately reduce groundwater production. Conversely, cleanup efforts at
the contaminated sites may allow some wells to return to service, which would increase the reliability of
groundwater production. In addition, the City is currently examining potential sites for adding three (3)
additional groundwater wells by the year 2010. This will allow City staff to rotate wells and reduce stress
on the distribution system. The recent perchlorate contamination issues demonstrate that water quality
concerns can impact water supply. By aggressively pursuing groundwater treatment solutions, the City will
avoid any long term effects on its water supply.

Water Use Provisions
Law
10631. A plan shall be adopted in accordance with this chapter and shall do all
of the following:
10631 (e) (I) Quantify, to the extent records are available, past and current water
use, over the same five-year increments described in subdivision (a), and
projected water use, identifying the uses among water use sectors including, but
not necessarily limited to, all of the following uses:
(A) Single-family residential; (B) Multifamily; (C) Commercial; (D) Industrial;
(E) Institutional and governmental; (F) Landscape; (0) Sales to other agencies;
(H) Saline water intrusion barriers, groundwater recharge, or conjunctive use, or
any combination thereof; and (I) Agricultural.
(2) The water use projections shall be in the same 5-year increments to 20 years
or as far as data is available.
Past, Current and Projected Water Use
As the City of Vernon has essentially reached "build-ouf' conditions, the City does not anticipate any
substantial growth in potable water usage, or number of connections, over the next 20 years. Since 1995,
new connections have been added at a rate about 1 % per year. Since 2000, new water demand has
actually decreased by a rate of about 1-2% per year, due in part to conservation efforts and in part to a
general slow-down in the region's economy. While new potable water connections are anticipated to level
off, consumption in all sectors is anticipated to increase at the low rate of population growth, an estimated
0.7%.
As discussed in Water Recycling, the City of Vemon is requiring that one existing and one future power
plant utilize recycled water for on-site cooling tower operation. The existing power plant (Malburg
Generation Station) currently uses 1,438 AFY of recycled water. The future power plant is projected to be
completed in two phases. Phase I, anticipated to be completed prior to 2010, will have an annual recycled
water demand of 6,834 AFY. Phase II, anticipated to be completed by 2015, will require an additional
6,666 AFY of recycled water. For the purposes of this plan, it has been assumed that Phase I and II will be
comprised of two (2) separate connections. Therefore, in 2015, the two power plants are projected to have
a combined recycled water demand of 14,938 AFY. Additional recycled water usage after 2015 is
projected at the low rate of population growth, an estimated 0.7% per year.
Table 5 illustrates Past, Current, and Projected Water Use 1995 - 2025 in acre-feet per year, and Table 6
illustrates Past, Current, and Projected Water Use 1995 - 2025 in number of customers per year.
Unaccounted water losses have averaged about 8% of total production in the City of Vernon, but last year
this number was a much fower 5%. This is attributed to the City's increased vigilance in using water
efficiently and removing wasteful practices. Unaccounted for water loss is projected to remain at 5% of
total water usage until 2025.

In the event of a water shortage, the City can distinguish between the various types of water users in order
to aid in water rationing. The City's water billing information clearly identifies categories for residential,
industrial, municipal and commercial users. Obviously, each would have different needs and different
appropriate rationing allocations. By identifying water users by category, the City is able to target specific
classes of users during water shortages.
Residential Sector
In the City 9f Vernon, residential water use accounts for less than 0.1 % of total water consumption, and is
minimal when compared to the industrial and commercial sectors. Average daily household use, which is
comprised entirely of small single family units, averages 290 gallons per day. Single residential
connections are projected to remain the same over the next 20 years, with annual consumption increasing
at the rate of population growth.

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
Commercial Sector
The Commercial Sector in the City of Vernon is comprised of a complex mix of customers, ranging from
restaurants, trucking firms, warehousing, garment firms, chemical distributors, and wholesale and retail
outlets. This sector accounts for almost 50% of the City's total water demand. In the future, the number of
connections are projected to level off, however usage will continue to slightly increase at the rate of 0.7%
per year, in accordance with population projections.
Industrial Sector
This sector accounted for approximately 50% of 2005 potable water usage. In the future, the number of
connections are projected to level off, however potable usage will continue to slightly increase at the rate
of 0.7% per year, in accordance with population projections.
Currently, all recycled water demand in the City of Vernon is attributed to an existing power plant (Malburg
Generation Station), with an annual demand of 1,438 AFY. There is a specific plan to construct an
additional power plant within the City of Vemon, which will also utilize recycled water. The future power
plant is projected to be completed in two phases. Phase I, anticipated to be completed prior to 2010, will
have an annual recycled water demand of 6,834 AFY. Phase II, anticipated to be completed by 2015, will
require an additional 6,666 AFY of recycled water. Additional recycled water usage after 2015 is projected
at the low rate of population growth, an estimated 0.7% per year.
Institutional/Governmental Sector
The City has a small, stable institutional/governmental sector accounting for 0.2% of the City's total water
demand. In the future, the number of connections are projected to level off, however usage will continue to
slightly increase at the rate of 0.7% per year, in accordance with population projections.

Supply and Demand Comparison Provisions
Law
10635 (a) Every urban water supplier shall include, as part of its urban water
management plan, an assessment of the reliability of its water service to its
customers during normal, dry, and multiple dry water years. This water supply
and demand assessment shall compare the total water supply sources available to
the water supplier with the total projected water use over the next 20 years, in
five-year increments, for a normal water year, a single dry water year, and
multiple dry water years. The water service reliability assessment shall be based
upon the information compiled pursuant to Section 10631, including available
data from the state, regional, or local agency population projections within the
service area of the urban water supplier.
Normal Supply and Demand Comparison
Table 7 compares current and projected water supply and demand. It indicates that in average
precipitation years, the City of Vernon has sufficient water to meet its customers' needs, through 2025.
This is based on continued commitment to conservation programs, maintaining current adjudicated
groundwater rights, additional imported water becoming available when needed from CBMWD, and the
ability to purchase recycled water as needed from CBMWD.

Recycled water supply from CBMWD will be necessary to meet the City's projected recycled water
demand from the two power plant projects. The City will continue to examine additional groundwater
leases, and imported water supplies to meet their water demands. Other water management options,
including expanding conservations efforts, will also be explored. See the Water Shortage Contingency
Plan section for further information.
Single Dry Year Supply and Demand Comparison
1992 was identified as the driest year in recent record based on City of Vernon production records. The
single dry year scenario investigates the effect of an isolated single dry period similar to this year occurring
in the future. During this year, as well as the previous year, total production dropped to the lowest levels
experienced between 1985-1995, approximately 88% of normal year production. Supply is therefore set at
88% of normal potable water year production levels (Table 8a). Potable water demand is taken from Table
3 and assumes that conservation would reduce the future potable demand by 10% (Table 8b).

It is not expected that potable water supply reductions would result in recycled water shortages. In the
event of a short-term recycled water shortage, existing and future agreements with CBMWD stipulate that
CBMWD will increase the supply of Tier 2 imported potable water to compensate for any disruption of
recycled water, regardless of the drought conditions in Central Basin. In the event of a long-term recycled
water shortage, both the existing and proposed power plants will maintain enough on-site emergency
storage to "power down" and terminate operations until the recycled water shortage is over. Therefore,
recycled water demands and supplies are assumed to be at normal levels during single dry years.
In the event of a historical single year drought, the City would experience a shortage during year 2025.
However, any deficit experienced during this period would be met by extracting additional groundwater
and expanding conservation efforts.

Multiple Dry Year Supply and Demand Comparison
The multiple dry period supply and demand comparison examines the effect of a historical multiple dry
period occurring in the future. The four sets of tables and figures that follow illustrate these comparisons at
five year increments from 2006 to 2025. The historical dry year period was identified as the three year
period from 1990-92. The supply production numbers for this period indicate that production dropped to
88% of normal production for multiple years during this time. In each five year increment, it is assumed
that the dry period will take place in the last three years of each period, with each dry year supply equating
to 88% of normal potable water supply. The "normal" supply and demand numbers for each year were
determined extrapolating the projections shown in Table 3. Conservation measures that will result in a
10% reduction in potable water demands are assumed to occur beginning the fourth year of each five year
increment.

It is not expected that potable water supply reductions would result in recycled water shortages. In the
event of a short-term recycled water shortage, existing and future agreements with CBMWD stipulate that
CBMWD will increase the supply of Tier 2 imported potable water to compensate for any disruption of
recycled water, regardless of the drought conditions in Central Basin. In the event of a long-term recycled
water shortage, both the existing and proposed power plants will maintain enough on-site emergency
storage to "power down" and terminate operations until the recycled water shortage is over. Therefore,
recycled water demands and supplies are assumed to be at normal levels during multiple dry years.
Multiple Dry Year Projected Supply and Demand Comparison
The comparison between supply and demand is shown in Tables 9 through 12. It is in the third year of
each analysis up to 2020 where demand exceeds supply, and the final three years of the 2020-2025
analysis as well. All supply figures presented did not explore the possible of securing additional
groundwater leases to augment projected supplies. A recent analysis of the Department of Water
Resources Water Master Records indicate that the potential to lease additional rights within the basin is
realistically limited to about 3,500 AFY, which is greater than the projected deficit in any given year.
In addition, during a declared water shortage, the Watermaster {Central Basin} may allow the City to over
pump 20 percent of its water rights; however, in doing so it must decrease its allocation by 20 percent the
following fiscal year. With this arrangement, the City can sustain itself during a declared water shortage.
The City manages its supply so that when additional water is needed, due to the possibility of a shortfall in
imported supply, these groundwater rights can be exercised. Figures 9 through Figure 12 show the trends
for supply, demand and storage for each five year increment.
Multiple Dry Year Projected Supply
Tables 9a through 12a show that projected supply is equivalent to normal year supply in the first two years
of each period and then follows the historical, 88% of normal potable water supply, three year dry period
pattern beginning the third year.
Multiple Dry Year Projected Demand
Tables 9b through 12b show that the demand is equivalent to normal year projected demand during the
first 3 years, and then potable water demand is reduced by 10% to reflect assumed conservation during
the last 2 years.

Water Demand Management Measures
Law
1063 I (f) Provide a description of the supplier's water demand management
measures. This description shall include all of the following:
(I) A description of each water demand management measure that is currently
being implemented, or scheduled for implementation, including the steps
necessary to implement any proposed measures, including, but not limited to, all
of the following:.................
The City of Vemon is committed to implementing water conservation and water recycling programs. This
Section discusses water conservation.
For the purpose of responding to the Urban Water Management Planning Act the City will address the 14
Demand Management Measures outlined in the Water Code. Descriptions of the City's water
conservation programs are provided below. The City has, in good faith, tried to address and comply with
all of the BMP targets listed in the CUWCC MOU where applicable.
DMM 1 -- Interior and Exterior Water Audits for Single Family and
Multi-Family Customers
IMPLEMENTATION DESCRIPTION: The City of Vemon's customer base primarily consists of Industrial
and Commercial customers. In the City of Vernon, residential water use accounts for less than 0.1 % of
total water consumption (Table 5). To date the City has not developed or implemented a residential water
use survey, although the majority of the single-family residences within the City have been retrofitted with
ultra-low flow toilets. As a primarily commercial/industrial City, water use for residential landscaping is
kept at a minimum.
DMM 2 -- Plumbing Retrofit
IMPLEMENTATION DESCRIPTION: As the City is comprised of primarily commercial and industrial
consumers and has a relatively small amount of residential users requiring plumbing retrofits beyond those
provided for in DMM14 (ULFT)
DMM 3 -- Distribution System Water Audits, Leak Detection and
Repair
IMPLEMENTATION DESCRIPTION: The City has conducted water audits and leak detection and repair
since 2001. A water audit was performed by the City on October 1995. This audit addressed leak
detection and repair, meter change-out, and unaccounted for water loss.
A leak detection and repair program for the City's water mains has not yet been implemented. However, a
program is planned for implementation in 2007. A meter change-out program has been implemented and
is an ongoing program performed by the City water maintenance staff.
Each year the City prepares an Annual Report to the Drinking Water Program, the last of which was
prepared for the 'year ending December 31, 2004. This report summarizes finished water produced,
purchased and sold and is used in conjunction with monthly operations reports to calculate verifiable use
December 2005
23
,.
CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
as a percent of total production. Unaccounted for water loss within the City of Vernon was approximately
5% of total production in 2005, a3% decrease over the past 10 years.
DMM 4 -- Metering with Commodity Rates
IMPLEMENTATION DESCRIPTION: The City is fully metered for all customer sectors. As the City is
primarily industrial and commercial and has a relatively low number of residential connections, dedicated
landscape meters are not feasible. The City charges one uniform rate for commodity use units of HCF
(Hundred Cubic Feet). Meters are read and billed monthly.
The City will continue to install and read meters on all new services, and will continue to conduct its meter
calibration and replacement program. Immediate attention is given to any metered amount which reflects
an unexpected variance.
DMM 5 -- Large Landscape Water Audits and Incentives
IMPLEMENTATION DESCRIPTION: As the City is primarily industrial/commercial, there are no large
landscaped areas within the City.
DMM 6 -- Landscape Water Conservation Requirements
IMPLEMENTATION DESCRIPTION: As discussed in DMM 5, the City is primarily made up of industrial
and commercial land uses and there are minimal landscaped areas within the City, as the majority of
properties have improvements (Le. buildings, parking lots, etc.) built to the property line.
DMM 7 -- Public Information
IMPLEMENTATION DESCRIPTION: The City promotes water conservation and other resource
efficiencies through billing inserts, which are mailed periodically. The City also provides information for
customers at the front desk of the Department of Community Services.
In addition, the City provides summary information on water usage on the monthly water bill, which
includes a comparison to the previous year's usage and presents daily average usage.
IMPLEMENTATION SCHEDULE: The City will continue to provide public information services and
materials to remind the public about water and other resource issues. The City will continue to provide
usage information on the monthly water bill.
DMM 8 -- School Education
IMPLEMENTATION DESCRIPTION: The City of Vernon's Water Operations Supervisor actively
participates in a school education program. The Water Operations Supervisor has given presentations at
the Vernon Elementary School, which is the only educational facility within the City. These presentations
highlight efficient use of resources and water conservation.
IMPLEMENTATION SCHEDULE: The City will continue its school education program.

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
-
DMM 9 -- Commercial and Industrial Water Conservation
IMPLEMENTATION DESCRIPTION: As the City is primarily made up of industrial and commercial
customers, all of its conservation programs focus on commercial and industrial accounts. As described in
DMM 3, the City has conducted water audits and leak detection and repair since 2001. A water audit was
performed by the City on October 1995. This audit addressed leak detection and repair, meter change-out,
and unaccounted for water loss.
Billing inserts have been supplied with the monthly water bills that promote conservation and other
resource efficiencies.
DMM 10 -- New Commercial and Industrial Water Use Review
IMPLEMENTATION DESCRIPTION: The City has implemented this DMM through its Water Department
and Building Section. All new building plans must be submitted to the Building Section for review and
approval. Water saving appurtenances and fixtures are a requirement of the approval process and are
required to obtain a permit.
A water consumption review is performed arid based upon the Building Section's estimated water use, an
appropriate size water meter is selected. This water meter factors in the water saving appurtenances
mentioned above.
IMPLEMENTATION SCHEDULE: The City will continue to implement this DMM through its Water
Department and Building Section.
DMM 11 -- Conservation Pricing, Water Service and Sewer Service
IMPLEMENTATION DESCRIPTION: The City of Vernon's commodity rate for water is the same for all use
types (i.e. commercial, industrial, and residential). During rationing, 6 HCF of water allotment is the
minimum amount that each customer will be supplied, due to health and safety considerations. During
periods of extreme water supply shortages, the City may need to raise water rates. This will be handled on
a case-by-case basis.
Sewer service is provided by the Sanitation Districts of Los Angeles County and sewer charges are the
responsibility of the Sanitation Districts.
DMM 12 - Water Conservation Coordinator
IMPLEMENTATION DESCRIPTION: The City's designated Water Conservation Coordinator is the
Directory of Community Services.
DMM 13 --Water Waste Prohibition
IMPLEMENTATION DESCRIPTION: Although there is no official water waste ordinance within the City,
City crews have been trained in the areas of water waste and actively monitor the City for water waste
activities.
DMM 14 - Residential Ultra-Low-Flush Toilet Replacement Program
IMPLEMENTATION DESCRIPTION: As a member agency to CBMWD, the City participates in CBMWD's
Ultra-Low-Flush Toilet (ULFT) distribution program. CBMWD's Ultra-Low-Flush Toilet (ULFT) distribution
program was established to provide the public with free high-quality ULFTs that conserve water. The intent
December 2005
25
.-
CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
.
of this program is to encourage the public to change out their older water-wasting toilets (3 gallons and up)
with new ULFTs that are available through this program
As the City is comprised of primarily commercial and industrial consumers and has a relatively small
amount of residential users, the majority of single-family residences within the City have been retrofitted
with ULFTs.

Water Shortage Contingency Plan
Preparation for Catastrophic Water Supply Interruption
Law
10632. The plan shall provide an urban water shortage contingency analysis
which includes each of the following elements which are within the authority of
the urban water supplier:
10632 (c) Actions to be undertaken by the urban water supplier to prepare for,
and implement during, a catastrophic interruption of water supplies including,
but not limited to, a regional power outage, an earthquake, or other disaster.
Water Shortage Emergency Response
In 1991, in accordance with CBMWD's Ordinance No.1-91-16, the City ofVemon adopted Ordinance No.
955, which enacted Article VI of Chapter 25 of the Code of the City of Vemon, ''Water Conservation",
containing Code Sections 25.100 through 25.111. Minimum requirements were outlined in this Ordinance
to protect potable water supplies and to establish standards for reductions in the use of water in the City of
Vemon.
During declared shortages, or when a shortage declaration appears imminent, Ordinance No. 995
establishes conservation measures for Phase I, Phase II and Phase III water shortages. These shortages
equate to maximum water supply deficiencies of 20%, 30% and greater, respectively. Restrictions are
outlined goveming acceptable water use for commercial, industrial, institutional and residential customers
during declared water shortages. Penalties for violations include increase water surcharges, as well as the
installation of flow restriction devices. Customers may tile applications for relief from these provisions with
the Director of Community Services of the City of Vemon.
In the event of an interruption of service from the CBMWD, the City of Vemon is capable of increasing
water production to compensate for the lack of purchased imported water. Currently, the City purchases
2.5 MGD from CBMWD, which accounts for approximately 26% of the City's average day demand. If this
supply were unavailable in a short-term emergency, the City is more than capable of increasing
groundwater production to mitigate the water shortage. In addition, a temporary connection can be made
between the City of Vemon system and Califomia Water Service Company's system. This connection can
be made between two fire hydrants that are adjacent to each other.
In the event of a power outage, the City can currently produce and supply 52% of average daily demand
utilizing back-up power generators. Within the next five years, the City of Vemon anticipates expanding
th.is capability in order to produce all average daily demands in the event of loss of power.
Be assured that the City recognizes the importance of the DMMs in reducing water demand and would
continue to implement the programs. Also, the City would increase media attention to the water supply
situation during a shortage and would step up public water education programs.
In the event of a major catastrophe, the City has prepared a Disaster Response Plan which identifies the
actions necessary for the City of Vemon to prepare for and conduct emergency operations to ensure
delivery of a safe, pure, and wholesome supply of water during disaster events. This plan was developed
December 2005
27
CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
using guidelines detailed in the "Conceptual Disaster Response Plan for Public Water Utilities" prepared
by the State of California Department of Health Services (1992). This plan identifies responsible
personnel, inventory of system resources including emergency resources, communications, as well as an
emergency procedures action plan. Specific components of the emergency procedures action plan include
damage assessment, water .supply logistics, and system repairs.
Finally, the City of Vemon is in contact with the top 10 water consumers, which accounted for over 40% of
average daily usage in 2004. Should the need arise, these customers can be immediately contacted to
make the appropriate adjustments in demand.
Supplemental Water Supplies
It is critical that the City set in place sources of water supplies in the event of an emergency. To offset
potential water shortages due to drought or disaster, the Watermaster (Central Basin) may allow the City
to over pump 20 percent of its water rights; however, in doing so it must decrease its allocation by 20
percent the following fiscal year. With this arrangement, the City can sustain itself during a declared, short-
term water shortage. The City manages its supply so that when additional water is needed, due to the
possibility of a shortfall in imported supply, these groundwater rights can be exercised.
The City is exploring dry year water transfer options with neighboring retail water wholesalers. A recent
analysis of the Department of Water Resources Water Master Records indicate that the potential to lease
additional groundwater rights within the basin is realistically limited to about 3,500 AFY.
Long Term Additional Water Supply Options
Water Transfers - The City is exploring dry year water transfer options with neighboring retail
water wholesalers. A recent analysis of the Department of Water Resources Water Master
Records indicate that the potential to lease additional groundwater rights within the basin is
realistically limited to about 3,500 AFY
Imported Water - The City currently purchases treated water from the Central Basin Municipal
Water District (CBMWD). According to the 2003 Purchase Agreement for Imported Water to be
Provided by Central Basin MUflicipal Water District (2003 CBMWD Agreement), the City has a
base allocation of 3,350 AFY, including a Tier 1 annual maximum of 3,015 AFY (90% of base
allocation). Additional water can be purchased from CBMWD; however, it will need to be
purchased at the Tier 2 water rate. Tier 2 imported water is available in unlimited quantities;
however, Tier 2 water supply could be reduced in the event of a drought situation.
The following table summarizes the actions the water agency will take during a water supply catastrophe.

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.
Rationing Stages and Reduction Goals
The City has developed a three stage rationing plan to invoke during declared water shortages. The
rationing plan includes mandatory rationing in order to obtain the associated customer reduction goal.

Priority by Use
Priorities for use of available potable water during shortages were based on input from the City
Emergency Response Team, citizen groups, and legal requirements set forth in the California Water
Code, Sections 350-358. Water allocations are established for all customers according to the following
ranking system:
· Minimum health and safety allocations for interior residential needs.
. Fire protection needs.
· Commercial, industrial, institutional/governmental operations (where water is used for manufacturing
and for minimum health and safety allocations for employees and visitors), to maintain jobs and
economic base of the community (not for landscape uses).
Note: It is not expected that potable water supply reductions would result in recycled water shortages. In
the event of a short-term recycled water shortage, existing and future agreements with CBMWD stipulate
that CBMWD will increase the supply of Tier 2 imported potable water to compensate for any disruption of
recycled water, regardless of the drought conditions in Central Basin. In the event of a long-term recycled
water shortage, both the existing and proposed power plants will maintain enough on-site emergency
storage to "power down" and terminate operations until the recycled water shortage is over.
Health and Safety Requirements
The City has assigned maximum allocation amounts for all user types based on customer's 1989 billing
records. In the event of a Stage II emergency, no customer shall use more than 85% of the amount used
during the corresponding billing period in 1989. Similarly, in the event of a Stage III emergency, each
customer is limited to 80%. A minimum water allotment of 6 HCF for each customer for safety and health
considerations during water rationing is also assured.
Water Shortage Stages and Triggering Mechanisms
As a member of CBMWD, the City coordinates water shortage alerts in conjunction with most neighboring
water retail agencies. The primary triggering mechanism for implementation for a staged alert would be a
request of compliance. issued by CBMWD.
Rationing stages may be triggered by a shortage in one water source or a combination of sources. The
City's potable water sources are groundwater and imported. Rationing stages may be triggered by a
supply shortage or by contamination in one source or a combination of sources. Because shortages
overlap Stages, triggers automatically implement the more restrictive Stage. Specific criteria for triggering
the City's rationing stages are shown in Table 15.

CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
10632 (g) An analysis of the impacts of each of the actions and conditions
described in subdivisions (a) to (f), inclusive, on the revenues and expenditures
of the urban water supplier...
10632 (g) [An analysis of the impacts of each of the] proposed measures to
overcome those [revenue and expenditure] impacts, such as the development of
reserves and rate adjustments.
The City currently has reserves that address, or mitigate, impacts to revenues and expenditures and allow
us to plan accordingly. Working capital, rate changes, capital improvements, and facility replacements are
planned using these reserve funds. When water supply shortages occur, the City could experience
financial hardship, in which case water rates would have to be increased accordingly.
Reduction Measuring Mechanism
Law
10632. The plan shall provide an urban water shortage contingency analysis
which includes each of the following elements which are within the authority of
the urban water supplier:
10632 (i) A mechanism for determining actual reductions in water use pursuant
to the urban water shortage contingency analysis.
Mechanism to Determine Reductions in Water Use
Under normal water supply conditions, potable water production figures are recorded daily, and reviewed
by Water Department Staff (Utilitymanl). Totals are then reported monthly to the Water Operations
Supervisor, and incorporated into the City's water supply report.
During a Stage II or Stage 1/1 water shortage, daily production figures are reported to Water Department
Staff (Utilityman I). The Water Operations Supervisor compares the weekly production numbers to the
target goals to verify that the reduction goal is being met. Monthly reports are sent to the City Council. If
reduction goals are not met, the Director of Community Services and Water will notify the City Council so
that corrective action can be taken.
During emergency shortages, production figures are reported to Water Department Staff (Utilityman I)
hourly and to the Water Operations Supervisor daily. Monthly reports will also be provided to the City
Council.

Water Recycling
Wastewater System Description
Law
10633. The plan shall provide, to the extent available, information on recycled
water and its potential for use as a water source in the service area of the urban
water supplier. To the extent practicable, the preparation of the plan shall be
coordinated with local water, wastewater, groundwater, and planning agencies
and shall include all of the following:
10633 (a) A description of the wastewater collection and treatment systems in
the supplier's service area...
Participation in Regional Recycled Water Planning
The City of Vernon has participated in the Central Basin Water Recycling Master Plqn. As both a water
agency (purveyor) and groundwater agency, the City has provided input on customer development, rates,
facilities and impacts. As mentioned in the "Water Source" section of this report, the City is currently
implementing a recycled water program, and anticipates completion by the year 2010.The City will
purchase tertiary water from CBMWD. The treated effluent will meet all requirements of Title 22 of the
California Code of Regulations.
Recycled water is one of the cornerstones of Central Basin's efforts to augment local supplies and reduce
dependence on imported water. Since the planning and construction of Central Basin's recycled water
system in the early 1990's, Central Basin has become a leader in producing and marketing recycled water.
This new supply can assist the City of Vernon in meeting the demand for non-potable applications such as
commercial and industrial processes. It is only limited by the infrastructure needed to deliver this source to
the City of Vernon.
Currently, the City purchases 1,438 AFY of recycled water from CBMWD in order to provide service for the
on-site cooling towers of a recently constructed power plant (Malburg Generation Station). In order to
provide this service, the City of Vernon has constructed almost 10,000 linear feet of recycled water
pipeline, capable of supplying recycled water from CBMWD. The City of Vernon has entered into an
agreement with CBMWD to provide recycled water to this power plant. In the event that the recycled water
supply is interrupted, this agreement stipulates that CBMWD will increase the supply of Tier 2 imported
potable water to compensate for any disruption of recycled water, regardless of the drought conditions in
Central Basin.
Recent market assessments, conducted by the City, have identified an additional power plant with on-site
cooling towers, anticipated to begin operations within the next five years. Phase I of this power plant,
anticipated to be completed prior to 2010, will have an annual recycled water demand of 6,834 AFY.
Phase II, anticipated to be completed by 2015, will require an additional 6,666 AFY of recycled water. An
agreement between the City of Vernon and CBMWD is currently being negotiated to provide recycled
water to this proposed power plant. Similar to the previous agreement, CBMWD will insure that if the
recycled water supply is interrupted, CBMWD will increase the supply of Tier 2 imported water to the City
in order to compensate for the disruption of recycled water, regardless of the drought conditions in Central
Basin. Furthermore, the City has begun working with CBMWD on the Southeast Water Reliability Project
which will provide the necessary infrastructure to provide this additional recycled water through a
proposed 42" diameter, looped pipeline.

wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge,
and other appropriate uses, and a determination with regard to the technical and
economic feasibility of serving those uses.
10633 (d) The projected use of recycled water within the supplier's service area
at the end of 5, 10, 15, and 20 years.
Recycled Water Currently Being Used
Currently, the City purchases 1,438 AFY of recycled water from CBMWD in order to provide service for the
on-site cooling towers of a recently constructed power plant (Malburg Generation Station). In order to
provide this service, the City of Vemon has constructed almost 10,000 linear feet of recycled water
pipeline, capable of supplying recycled water from CBMWD. Appendix D illustrates the existing recycled
water infrastructure within the City of Vemon.
Potential Uses of Recycled Water
Recent market assessments, conducted by the City, have identified an additional power plant with on-site
cooling towers, anticipated to begin operations within the next five years. Phase I of this power plant,
anticipated to be completed prior to 2010, will have an annual recycled water demand of 6,834 AFY.
Phase II, anticipated to be completed by 2015, will require an additional 6,666 AFY of recycled water. An

Encouraging Recycled Water Use
Law
10633. The plan shall provide, to the extent available, information on recycled
water and its potential for use as a water source in the service area of the urban
water supplier. To the extent practicable, the preparation of the plan shall be
coordinated with local water, wastewater, groundwater, and planning agencies
and shall include all of the following:
10633 (e) A description of actions, including financial incentives, which may be
taken to encourage the use of recycled water, and the projected results of these
actions in terms of acre-feet of recycled water used per year.
The City's Philosophy
It is the City's philosophy that recycled water shall be used within the jurisdiction wherever its use is
economically justified, financially and technically feasible and consistent with legal requirements,
preservation of public health, safety and welfare of the environment.
The City will evaluate all proposed water users and will examine implementing mandatory recycled water
use for all industrial and commercial users when deemed economically and technically feasible. Although
this will not provide a reduction in water rates at this point, thus resulting in a financial incentive, the
recycled water will be exempt from rationing in the event of a drought.
Proposed Actions to Encourage Use of Recycled Water
The City of Vemon is requiring that a future power plant site, anticipated to begin operations within the
next five years, must utilize recycled water for on-site cooling tower operation. Phase I of this power plant,
anticipated to be completed prior to 2010, will have an annual recycled water demand of 6,834 AFY.
Phase II, anticipated to be completed by 2015, will require an additional 6,666 AFY of recycled water. An
agreement between the City of Vernon and CBMWD is currently being negotiated to provide recycled
water to this proposed power plant. The City has begun working with CBMWD on the Southeast Water
Reliability Project which will provide the necessary infrastructure to provide this additional recycled water
through a proposed 42" diameter, looped pipeline.
Recycled Water Optimization Plan
Law
10633. The plan shall provide, to the extent available, information on recycled
water and its potential for use as a water source in the service area of the urban
water supplier. To the extent practicable, the preparation of the plan shall be
coordinated with local water, wastewater, groundwater, and planning agencies
and shall include all of the following:
10633 (f) A plan for optimizing the use of recycled water in the supplier's
service area, including actions to facilitate the installation of dual distribution
systems and to promote recirculating uses.
Plan for Optimizing the Use of Recycled Water
The City is anticipating purchasing a total of 14,938 AFY of recycled water from CBMWD by 2015. This
figure represents the water needs of two power plants, specifically their on-site cooling towers.
December 2005
36
CITY OF VERNON 2005 URBAN WATER MANAGEMENT PLAN
Participation for these particular accounts will be mandatory, and optimization is based upon efficient
cooling tower operation. Please see Appendix D for a map of the existing and future reclaimed water
distribution system within the City of Vernon.

URBAN WATER MANAGEMENT PLAN
STAFF REPORT
Infrastructure Engineering has prepared an Urban Water Management Plan (UWMP) for the City that
fulfills the requirements of the California Water Code 10644( a). The attached UWMP provides a description of
the City's water distribution system, historical and projected water use, and an overview of existing water
supplies. Also included in the UWMP is an evaluation of the water conservation best management practices and
a water shortage contingency plan (Ordinance No. 995, Section No. 25.1 03).
The UWMP explores the protocol that must be adhered to in the event of a drought or catastrophic
happening. It is, however, up to the Vernon City Council to determine when an increase in the water shortage
has occurred and when corrective measures must be taken pursuant to a Phase I Shortage, Phase n Shortage and
Phase ill Shortage. The protocol with respect to the above-mentioned water shortage measures are discussed
briefly below:
Phase I Shol1:a2e:
A Phase I Shortage'is enacted by the Vernon City Council when it is determined that the City will
likely suffer a water shortage of more that ten-percent (10010) and up to twenty-percent (20010) of City water
supplies. Several restrictions will be enacted to reduce water consumption on a Citywide basis. These
restrictions include:
· No washing of sidewalks, driveways and/or paved areas;
. Hoses must be equipped with shutoff nozzles;
. Restaurants shall not serve water to customers unless requested by customer;
. Customers shall repair leaks to interior and exterior plumbing leaks promptly;
· Landscape areas shall not be watered more than every other day and shall not be watered between the
hours of 10:00 a.m. and 4:00 P.M.; and
· No customer shall allow landscape water to run off to City sidewalks, streets and/or any paved areas as
a result of incorrectly positioned irrigation devices.
Phase II Shol1:a2e:
A Phase n Shortage is enacted by the Vemon City Council when it is determined that the City will
likely suffer a water shortage of more that ten-percent (20%) and up to twenty-percent (30010) of City water
supplies. Additional restrictions over and above Phase I requirements will be enacted to reduce water
consumption on a Citywide basis. These restrictions include:
· The restrictions listed under Phase I shall be in effect, except that landscape use shall be modified to
mandate irrigation use eveIY third day between the hours of 6:00 a.m. and 6:00 p.m.; and
· No customer shall use in excess of eight-five percent (85%) of the amount used on the premises during
the corresponding billing period during the 2005 ca1endaryear.
..
~
Phase ill Shol1a2e:
A Phase I Shortage is enacted by the Vemon City Council when it is detennined that the City will
likely suffer a water shortage of more that thirty-percent (30%) of City water supplies. Severnl additional and
modified restrictions over and above Phase IT requirements will be enacted to reduce water consumption on a
Citywide basis. These restrictions include:
. The restrictions listed under Phase IT shall be in effect, except that there shall be no outside watering of
landscape areas at anytime except by bucket or other such container;
. The use of water from fire hydrants should be limited to fire fighting and related activities; and
. No customer shall use in excess of eighty-percent (80010) of the amount used on the customer's
premises during corresponding billing period of the 2005 calendar year.
In conclusion, the above-mentioned restrictions will include but are not limited to mandatory reduction
in landscape use, hosing of industrial facilities, and fire hydrant use. Other uses of City water for municipal
purposes shall be limited to activities necessary to maintain the public health, safety and welfare of the general
public. In addition, in the event of a long-term drought there is a possibility that the City's MWD water supplies
could be reduced drastically and therefore the City would have to place more emphasis on its groundwater
supplies making conservations measures that much more important.
