Executive Suimmary
The Urban Water Management Planning Act (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 prepare and adopt an Urban Water Management Plan (UWMP). The
Act also requires urban water suppliers to update the UWMP in years ending in five and zero,
using a 20-year planning horizon. The City of El Segundo (City) has prepared this UWMP in
accordance with all requirements set forth in the State of California Water Code Sections 10610
through 10657.
The City is a retail water supplier to both residential and commercial customers. This UWMP
describes the water system and includes a description of the water supply sources, historical and
projected water use, and a comparison of water supply to water demands during normal, single
dry, and multiple dry years. This Plan also addresses the Water Conservation Act of 2009
(SBx7-7) requirements, including the evidence of successfully hitting 2020 water use targets.
The City is located in the Los Angeles Basin, approximately 1.5 miles south of Los Angeles
International Airport (LAX). The area is a semi -arid desert environment receiving less than
14 inches of rainfall annually. The City manages and operates the domestic water system that
serves a residential population of approximately 17,000. The residential population of the City is
expected to increase marginally over the next 25 years as the residential areas are virtually built-
up with no substantial vacant land available for development.
The water system consists of approximately 57.5 miles of main pipelines and serves potable water
to a 5.5 square mile area. The City's water system is comprised of one pump station, two storage
reservoirs, and one elevated storage tank. There are currently two available water supply sources;
imported water from the Colorado River and State Water Project (SWP) (delivered via the West
Basin Municipal Water District (WBMWD)) and recycled water for landscaping irrigation and
industrial use (also supplied by the WBMWD). In addition, there are four interconnections with
three neighboring water agencies; Los Angeles Department of Water and Power (LADWP), City
of Manhattan Beach, and California Water Service, that can be activated during emergency
situations.

City of El Segundo — 2020 Urban Water Management Plan
Key factors that affect City water demands are population dynamics, changes in land use
development, industrial growth, and reductions in annual rainfall. For the City, population and
rainfall have historically exhibited the greatest influence. Usage of water per capita per day ranged
primarily between 450 and 600 Gallons per Capita per Day (GPCD) during 2001 to 2010 and has
since been trending lower. Consequently, Fiscal Year (FY) 2019 to 2020 had the lowest per capita
water use in the past 20 years. Consumption has ranged from a low of 307 GPCD in 2020 to a
maximum of 801 GPCD in 2001. The average use per day during the period from 2001 through
2020 was 470 gallons per person.
In FY 2020, the City used 5,489 acre-feet of potable water, as measured by metered sales and
estimated distribution system losses. Average water deliveries, are broken down into the following
sectors

City of El Segundo — 2020 Urban Water Management Plan
Note: Units in acre-feet per year
Note: Water losses for 2020 were still under development at the time of this report. FY 2019 volumes were assumed
for the planning purposes. However, water losses have consistently reduced each FY for the past four years. It it likely
water losses are less than the estiamate utilized for this table.
In order to determine the twenty percent per capita water use reduction by the year 2020 required
by SBx7-7, the City utilized the California Department of Water Resources (DWR) methods to
determine the baseline, interim, and water use target values. The City is part of the WBMWD that
has formed a regional alliance and has thus determined its baseline and target values both
individually and as part of the alliance. The individually calculated baseline for the City is
513 GPCD, the interim target in 2015 was 462 GPCD, and the target for 2020 compliance was
411 GPCD. The actual 2020 GPCD was 307. Therefore, the City has successfully met the 2020
target goal.

Note: All values are in Gallons per Capita per Day (GPCD)
Note: Values were determined utilizing the Methodology 8 document
Note: Corresponds to SB X7-7 Compliance Form, Table 9.
The City utilizes both potable and recycled water. The City is 100% dependent on imported water
purchased from WBMWD for its potable water supply and does not anticipate using groundwater
as a source of potable water. In addition to distributing potable water, the City is part of WBMWD's
recycled water system. The recycled water is used for industrial applications and irrigation.
Due to the slow rising population and the per capita demand reduction required by SBx7-7,
projected water supplies needs are expected to decrease from 2015 to 2035. The total projected
potable and recycled water supplies available to the City through WBMWD are shown in
Table ES-4.
Table ESA: Water Supplies - Current and Projected
Note: Values were obtained from the West Basin Municipal Water District Water Use Report.
Note: Units in acre-feet per year
All potable and recycled water supplies are provided through the WBMWD, which is supplied
through the Metropolitan Water District of Southern California (MWD) from the Colorado River
and the SWP. Since the supply is not directly obtained by the City, the determination of reliability
is largely determined by WBMWD and MWD analyses to provide a consistent water supply to the
City during normal, single dry, and multiple dry years. Both WBMWD and MWD have declared
the water supply reliable on both district's 2020 UWMPs.

It should be noted these models do not take into account water reduction measures,
improvements in water -use efficiencies, or limitations to increases in water demands based on
reduced population growth. Additionally, negative differences in water supply are not intended to
implicate that the City will not be able to provide sufficient water. Rather, these negative
differences represent potential increases in purchased water which West Basin has declared it

City of El Segundo — 2020 Urban Water Management Plan
will be able to meet in the event of a water shortage scenario. This plan assumes that City will be
able to meet water demands for any hydrology scenario over the next twenty years.
With population growth, energy shortages, earthquakes, and the threat of terrorism experienced
by California; maintaining the gentle balance between water supply and demand is a complicated
task that requires planning and forethought. In the event that a water shortage occurs, simple
measures can be implemented to conserve the water supply at a public level. Below, stages are
discussed during which various conservation measures will be imposed by the City of El Segundo,
beginning with voluntary conservation, and leading to various stages of mandatory compliance in
the event that the water supply experiences shortages of up to a 50 percent reduction in the water
supply. Implementation of the stages detailed below will occur on an emergency basis.

Note: Coordinates with WUE table 8-1
The City works with the WBMWD to implement water conservation techniques to reduce the total
demand of water throughout the City and WBMWD. Together, the City and WBMWD implement
the seven required Demand Management Measures (DMMs) within the City. WBMWD is a
signatory on the California Urban Water Conservation Council (CUWCC) Memorandum of
Understanding (MOU) regarding urban water conservation in California. CUWCC represents a
diverse group of water supply agencies dedicated to establishing Best Management Practice
(BMP) guidelines toward implementing conservation measures and managing supply demands.
The following table summarizes correlation between the BMPs/DMMs. DMM 7 for other DMMs
provided by the City, is not included on the table as it is universally applicable.

INTRODUCTION OVERVIEW
The California State Legislature passed AB 797, the Urban Water Management Planning Act (Act)
of 1983, which became effective January 1, 1984. 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 prepare and adopt an Urban Water Management Plan
(UWMP). The act also requires urban water suppliers to update the UWMP in years ending in five
and zero using a 20-to-25-year planning horizon. The City of El Segundo (City), a retail water
supplier, fits the defined criteria and has prepared this UWMP addressing the requirements set
forth in the State of California Water Code Sections 10610 through 10657.
Since its passage, many amendments have been added to the Act. These changes are intended
to encourage increased regional planning and the cooperative management of California's most
precious commodity - water. As a result, UWMPs have evolved to become:
• Foundation documents and sources of information for Water Supply Assessments and
Written Verification of Water Supply,
• Long range planning documents for water supply,
• Source data for the development of regional water plans,
• Source documents for cities and counties preparing their General Plans, and
• Key components of Integrated Regional Water Management Plans.
For the City, the benefits of updating the UWMP extend beyond legislative compliance. This
document is a reference document intended to complement other UWMPs by analyzing
conservation issues and the water supply available to the City. An effective UWMP aimed at
developing a greater level of water conservation, awareness, and reliability requires the
coordinated efforts on key tasks by the Department of Water Resources (DWR), West Basin
Municipal Water District (WBMWD), and City residents. This document also summarizes the
current and proposed water management activities performed by the City to provide dependable,
adequate and safe water. The UWMP further identifies proposed projects with a description of
resulting water costs, benefits, and implementation schedule.
Prepared by: Risk Management Professionals, Inc.
Specifically, the goals of this plan are:
• To provide a local perspective on current and proposed water conservation programs,
• To review current conservation programs and efforts,
• To evaluate potential conservation methods and identify improvements, as appropriate to
the City programs,
• To provide a general framework for the development of mechanisms for coping with both
short-term and long-term deficiencies in regional and/or local water supplies, and
• To serve as a flexible plan that can be updated periodically to reflect changes in regional
and local trends, conditions and conservation policies (at least once every five years in
accordance with Section 10621 and 10644 of AB 797).
In compliance with the State mandate and accordance with the best practices of water
management, the City has prepared this UWMP.
The California Water Code changes since 2015 are summarized below, and details of the

unconstrained demand as the expected water use in the upcoming

The new requirements for a water supply analysis are largely in the
application of that analysis to the new Drought Risk Assessment
(DRA), Water Shortage Contingency Plan (WSCP), and consideration of
climate change in future projections. In this section, the conclusions
drawn from the water supply characterization integrate into a specific

fewer supply augmentation actions or demand management actions

The new UWMP requirements is manifest in the application of new
criteria to the Water Use Analysis in Chapter 4, the Water Supply
Analysis in Chapter 6, and the resulting water service reliability
assessment in this chapter —including the requirement for a five -
consecutive dry years analysis compared to the 2015 UWMPs, which
included only a three-year analysis. A new DRA is now also required
under California Water Code (Water Code) Section 10635, and it
must be prepared as a component of the 2020 UWMP. The DRA
requires a methodical assessment of water supplies and water uses
under an assumed drought period that last five consecutive years.
The newly required WSCP is described in Chapter 8. Supply capacity

SYSTEM DESCRIPTION
General Location Overview
The City of El Segundo ("City") is located in the Los Angeles Basin on the coast approximately
1.5 miles south of LAX airport. Water is considered a limited natural resource given the climate,
with the majority of domestic water imported from as far away as the Colorado River and Northern
California. Due to the potential for Colorado River supplies to be reduced because of Federal
requirements, the Metropolitan Water District of Southern California and its member agencies,
including the West Basin Municipal Water District (WBMWD), may need to look to other sources
to supply their customers with water.
The City's residents and businesses consume an average of 5 million gallons of water per day.
Water conservation represents the most cost-effective and environmentally sound way to reduce
current and future demand. Reclaimed or recycled water is used for landscape irrigation, park
and school ground irrigation, industrial use, and for groundwater recharge. Landscaping with
drought -tolerant plants represents another effective method to help conserve water. Gardening
accounts for a large percentage of residential water use. Drought -tolerant plants, shrubs, and
trees are specially adapted to grow well in regions that get little, or infrequent amounts of normal
rain. The City has long promoted efficient water use through education, public information, and
municipal water management programs.
Water System Overview
The City manages and operates the domestic water system. The City's water system serves a
residential population of approximately 16,777. The system consists of approximately 57.5 miles
of main pipelines and serves potable water to a 5.5 square mile area. The City's water system is
comprised of one pump station, two storage reservoirs, and one elevated storage tank. There are
currently two available water supply sources; im
ported water from the Colorado River as well as
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
State Water Project supplies and recycled water for landscaping irrigation and industrial use
supplied by the WBMWD. In addition, there are four interconnections with three neighboring water
agencies; Los Angeles Department of Water and Power (LADWP), City of Manhattan Beach, and
California Water Service, that can be activated during emergency situations. The City obtains
approximately 52 percent of its water supply from WBMWD surface water, and 48 percent from
recycled water, as is described in their 2005 Water Master Plan. Table 3.1.1 and 3.1.2 summarize
the specifications of the aforementioned facilities as well as import capacity.

The City's economy has numerous aviation -related and petroleum -related industries and
operations. In 1911, Chevron began its second refinery which is the primary user of recycled
water within the City.
In 1930, the Los Angeles International Airport opened north of the City, which has led to the
concentration of aerospace and aviation -related firms in the area. Many large aerospace
companies have facilities in the City, including Boeing, Raytheon, Lockheed Martin, Northrop
Grumman, and The Aerospace Corporation, which is headquartered there. It is also home to the
Los Angeles Air Force Base and the Space and Missile Systems Center (SMC), which is
responsible for space -related acquisition for the military.
When it comes to evaluating socioeconomic correlations to increased community water use and
ultimately, water insecurity, low-income areas are of particular interest. Low-income individuals
are often limited financially and can only afford older rundown homes with less upkeep. Buildings
of that nature tend to lack proper piping connections, water fixture sealings, etc. making them
prone to drips, leaks, and floods. Poor water control characteristics such as these raise a red flag.
The U.S. has seen a gradual increase in overall GDP Growth Rates from 2013 through 2018 at
an average of 0.19% a year, The City has also seen a steady increase in median household
incomes starting at $85,727 in 2013 and progressing all the way up to $109,577 in 2019
(www.censuLgov/guickfacts). This figure is nearly $35,000 more than the national average
supporting the assumption that vast majority of City residents have adequate access to drinking
water. That said, 5.9% of the population report incomes below the poverty line which is almost

6% percent less than the state poverty rate. While this percentage only represents a small portion
of the community, the City is conscious of the socio-economic impacts to those individuals.
Unemployment can impact water use according to a study done by Cranfield University.
According to research, household water consumption changes significantly after the start of the
COVID-19 lockdown. Although the study was not focused on the City, the water use patterns for
the unemployed are likely similar. At home activities such as showering, laundry, gardening, etc.
can happen more frequently when individuals increase time spent at home. As the City's
unemployment rate fluctuates, the City may find a correlation between water use and
unemployment.

current (2020) values, anticipated population growth.
Prepared by: Risk Management Professionals, Inc. I=
City of El Segundo— 2020 Urban Water Management Plan
Residential Sector
Table 4.1.6 provides estimates for the projected residential water demand for the City. Due to the
lack of available space, the City does not have plans for significant new residential development
in the near future. In the next 20 years, some form of residential redevelopment may occur;
however, such development is not expected to place a heavy demand on the City's water supply.
Commercial/Institutional/Government Sectors
Current and projected water demands for the City's commercial and institutional/governmental
sectors are shown in Tables 4.1.5 — 4.1.6.
Industrial Sector
Industrial water demand accounts for a majority of the water use in the City. In FY 2019-2020,
industrial users accounted for greater than 55% of the sales, with 3,016-acre feet (AF) of water
delivered. The Chevron El Segundo Refinery is the largest single customer, accounting for
approximately 76% of the industrial water demand for FY 2019-2020. The current and projected
industrial water demands are shown in Tables 4.1.5 and 4.1.6.
Landscape Sector
The current and projected water demands for landscape irrigation are shown in Tables 4.1.5 and
4.1.6. Considering the implementation of the Water Conservation in Landrdinance No.
1437 and the City's robust recycled water system, landscape irrigation is expected to remain
stable throughout the planning horizon.
Agricultural Sector
The City does not provide potable water for agricultural uses.
Other
The City's firefighting water use is included in the Other category, and its projections are included
in Tables 4.1.5 and 4.1.6.
Distribution System Losses
The City's distribution system losses were estimated using FY 2018-2019 data and the American
Water Works Association (AWWA) water audit methodology and software. Distribution system
losses were then projected for the next 20 years using the current ratio of water losses to total
water deliveries (0.003%). Refer to Appendix D for the complete AWWA Water Audit Software
calculations.

In order to improve the Sacramento -San Joaquin Delta, in 2008 Governor Schwarzenegger
directed State water agencies to develop a plan to achieve a twenty percent per capita water use
reduction by the year 2020. The Water Conservation Act of 2009 (Senate Bill X7-7), passed in
November 2009, provided the legislative framework to implement the conservation goals, and
required retail water suppliers to detail their strategy for achieving the reduction requirement in
their 2010 Urban Water Management Plan Updates. The Urban Water Management Planning Act
and SBx7-7 information can be found using the links provided.
Explicit methodologies were developed by the California Department of Water Resources (DWR)
to assist retail water suppliers in complying with the Water Conservation Act of 2009, and they
are detailed in the technical document, Methodologies for Calculating Baseline and Com liance
Urban Per Capita Water Use, DWR, March 2016. The City of El Segundo (City) utilized the DWR
methods when determining its baseline, interim, and water use target values (20x2O2O targets),
the steps of which are described in detail in the Methodologies document. A summary of the
calculations is provided in DWR's SB X7-7 Verification Form, Appendix D
Water suppliers are given the option of determining their 20x2020 target values either individually,
or through a regional alliance. The City is part of the West Basin Municipal Water District that has
formed a regional alliance, and has thus determined its baseline and target values both
individually and as part of the alliance. The City's individual target values are provided in this
section. The regional alliance's values can be found in the West Basin Municipal Water District's
2020 Urban Water Management Plan (UWMP) Update, once available.
For the 2015 UWMP Update, DWR determined that significant discrepancies existed between the

the City recalculated its baseline population numbers for years 2001 — 2010 during the 2015
UWMP Update using 2000 and 2010 Census data. A summary of the revised baselines and

The City of El Segundo (City) utilizes both potable and recycled water. The City obtains its potable
water from a single source: purchased through the West Basin Municipal Water District (WBMWD),
who in turn receives the water through the Metropolitan Water District of Southern California
(MWD). The City purchased a total of 5,775 acre-feet (AF) of potable water for a population of
approximately 16,700 in 2020. In addition to distributing potable water, the City is part of WBMWD's
recycled water system. The City delivered 8,974 AF of recycled water in 2020 for landscape
irrigation and industrial purposes. Due to the slow decreasing population and the per capita demand
reduction required by SBX7-7, imported water needs are expected to decrease slightly from 2020
to 2035, with a projected decrease of 3% over the 20-year planning horizon. Due to the lack of
planned expansions to the City's recycled water system, recycled water needs are expected to
remain relatively stable. More information comparing the projected water supply and demand can
be found in Chapter 7.
Although the City overlies the West Coast Subbasin, one of the four subbasins of the Coastal Plain
of Los Angeles Basin, the City does not anticipate using groundwater as a source of potable water.
Currently, the City is 100% dependent on imported water from WBMWD and MWD for its potable
water supply. WBMWD's 2015 Urban Water Management Plan (UWMP) Update identified plans to
reduce its imported water use by 17% within the next 20 years through diversifying its water
sources; namely developing a full-scale ocean water desalination plant and expanding recycled
water use. The 2020 WBMWD UWMP is not available for review, so updates to this information is
not readily available at this time. Desalination and recycled water are discussed in more detail in
subsequent sections.
The total current and projected potable and recycled water supplies available to the City through
WBMWD are shown in Tables 6.1.1 and 6.1.2. The projected values are based on the estimated
demands outlined in Table 4.1.6 for the next 20 years. Water desalination is not reported in
Prepared by: Risk Management Professionals, Inc..
City of El Segundo — 2020 Urban Water Management Plan
Table 6.1.1 because WBMWD will be the operator of the desalination plant. Although the City may
purchase desalinated water, it will be part of the overall purchased water supply from WBMWD,
and therefore will be accounted for in the City's imported water supply and not through desalination.

Wholesale Water Supply
Water for use in the City is purchased through the WBMWD. According to its FY 2014-2015 Water
Use Report, 60% of WBMWD's supply is from imported sources, 19% from groundwater, and the
remainder is recycled water, desalination, and conservation efforts. However, WBMWD does not
supply groundwater to retail agencies. Rather, agencies within the WBMWD's service area rely on
groundwater production to meet a portion of their retail demand.
The majority of water supplied to WBMWD is from MWD as part of the State Water Project (SWP).
The SWP is a series of reservoirs, aqueducts, and pumping facilities that convey water from
Northern to Southern California. The water for use within the City is collected and delivered to MWD
via the SWP and Colorado River and is fully treated at the Weymouth Filtration Plant, where it is
then transferred to WBMWD. In 2015, MWD delivered approximately 113,000 AF of water to
Prepared by: Risk Management Professionals, Inc..
City of El Segundo — 2020 Urban Water Management Plan
WBMWD, of which 8,127 AF was sold to the City for distribution. The quality of the imported water
is shown in the following table: WBMWD does not conduct their own water quality testing and,
instead, monitors MWD's sampling and testing program.

Note: At Lake Mathews - from 2020 MWD Annual Water Quality Report, Table 4-3
Note: At Castaic Lake - from 2020 MWD Annual Water Quality Report, Table 4-3
The City has provided the following estimates for water supplies in order to meet demands. The
findings from the MWD 2015 UWMP Update have confirmed that projected supplies under the
single dry -year and multiple dry -year conditions would be sufficient to meet expected demands from
member agencies from 2020 through 2035. The 2020 MWD UWMP is not available to update this
information for the 2020 City UWMP draft.

Recycled Water Supply
The City provides recycled water for multiple uses throughout its service area, including tertiary
water (Title 22) for irrigation and industrial uses, nitrified water for industrial cooling towers, pure
reverse osmosis (RO) water for refinery low-pressure boiler feed water; and, ultra -pure RO water
for refinery high-pressure boiler feed water. The City's recycled water system is discussed in detail

City of El Segundo — 2020 Urban Water Management Plan
WBMWD and MWD seek out opportunities for water transfer and exchanges to ensure reliability
within their respective service areas. Water transfers and exchanges help water suppliers
distribute water effectively to areas with limited water supplies. For example, the MWD accepts
water through the SWP and Colorado River for distribution throughout Southern California. The
City, although not directly involved in the planning of these opportunities, may benefit from
additional water supplies as a result of MWD and WBMWD's efforts in securing water transfers
and exchanges. Information on new transfer and exchange opportunities to the MWD and
WBMWD can be found in their respective 2020 UWMPs.
The City is not currently exploring the possibility of using desalinated water as a water source
independently. However, WBMWD has been testing the feasibility of a seawater desalination
plant over the last ten years to determine if desalinated water can be used as a high quality and
reliable potable water source. In addition, MWD is also supporting various agencies in determining
the feasibility of using desalinated water as a water source. As an end user of water supplied
through WBMWD and MWD, the City may receive water, or benefit in other ways (i.e. increased
supplies and reliability), as a result of these efforts in discovering the opportunity for seawater
desalination. Therefore, a brief description of WBMWD and MWD's efforts in desalination are
discussed.
WBMWD Desalination Project
With recent advances in membrane and reverse osmosis technologies, seawater desalination
has become cost competitive with MWD imported water, and therefore has become economically
feasible. To capitalize on this, WBMWD began a pilot project in 2002 to determine if seawater
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
desalination was technically feasible. The pilot project, which ran for seven years, was located at
the El Segundo Power Plant within the City. Using microfiltration pretreatment and reverse
osmosis, the plant was capable of desalting approximately 20 gallons per minute of raw ocean
water. The goals of the project, as identified by the WBMWD 2010 UWMP, were to identify optimal
performance conditions and evaluate the water quality characteristics. Throughout the operation,
water quality tests were extensively conducted to determine if the desalinated water met all
applicable water quality standards. It was determined that the plant could consistently and reliably
produce high quality potable water that met drinking water standards.
The next step towards developing desalinated water was to initiate a full scale project. In 2009,
WBMWD received all necessary permits to commence construction on of a full scale
demonstration desalination plant. The plant was able to produce 50,000 gallons per day of potable
water and operated until 2014. This plant was used to develop a design basis for future
desalination plants that can provide potable water. In its 2015 UWMP, the WBMWD stated it was
developing an Environmental Impact Report (EIR) for a full scale ocean water desalination facility,
with a planned capacity of 21,500 AFY and online date of June 2023. No update is available on
the status of the project.
MWD Desalination Support
The City is not currently exploring the possibility of using desalinated water as a water source
independently. MWD joined the National Alliance for Water Innovation (NAWI) in 2020 and has
reported three (3) desalination projects within its service area in the 2020 UWMP.
In 2001, MWD created the Seawater Desalination Project (SDP) to explore the potential for using
seawater as a long-term water supply. The SDP provided incentives for its member agencies to
develop water through desalination; up to $250 per AF for all produced supplies. Since its
inception, MWD has entered into agreements with its member agencies to fund three (3) local
seawater desalination projects amounting to 46,000 AFY of potential production. In October 2014,
MWD added seawater desalination projects into its Local Resources Program (LRP), replacing
the SDP program and increasing the incentives to $340 for produced supplies (recycled water,
recovered groundwater and desalinated seawater). In June 2020, MWD's SDP agreements with
all three (3) member agencies expired.
According to the MWD 2020 UWMP Update, Table 3-11, the Claude Bud Lewis Carlsbad
Seawater Desalination production was estimated as 43,868 acre-feet in 2020. In addition, Table
3-13, in the same report, lists three (3) sweater desalination projects under development within
MWD's service area. Table 6.4.1 shows the projected supplies provided by these seawater
desalination plants.

The City is committed to potable water conservation through the treatment and distribution of
recycled water for non -potable uses. This effectively decreases the potable water that must be
purchased through WBMWD and MWD, and is a significant part in the statewide effort to conserve
and manage potable water resources. The City receives recycled water from the WBMWD's
recycled water system, which was originally constructed in the early 1990's. Since then, the West
Basin has become an industry leader in water re -use.
WBMWD purchases treated wastewater from the Hyperion Wastewater Treatment Plant
(Hyperion / Hyperion WWTP). Hyperion, located in the City of Los Angeles, has served to clean
wastewater from Los Angeles County for over 100 years. Throughout its history, Hyperion has
been upgraded to meet increasing wastewater treatment demands and all regulatory
requirements for treated wastewater. The Hyperion WWTP does not treat wastewater to recycled
water standards; therefore, WBMWD has an agreement to purchase secondary treated
wastewater from the Hyperion WWTP so that it may be treated further to acceptable recycled
water standards. The wastewater is then sent to the Edward C. Little Water Recycling Facility
(ECLWRF), a water reclamation plant that can treat effluent from the Hyperion WWTP to recycled
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
water standards for distribution throughout WBMWD's service area.
In FY 2014-2015, WBMWD distributed 29,110 AF of recycled water, according to the WBMWD's
FY 2014-2015 Water Use Report. Over the last ten years, WBMWD has distributed over 238,000
AF of recycled water, helping to preserve the region's drinking water supplies. For more
information of the WBMWD's recycled water system, refer to the WBMWD's 2015 UWMP update.
The City maintains its own wastewater division, which is responsible for the collection of
wastewater and the maintenance of the sewer system and transportation lines. The sewer system
is split into two portions; the portion of the sewer system located to the west of Sepulveda
Boulevard flows to the Hyperion WWTP in Los Angeles; while the area to the east of Sepulveda
Boulevard flows through the system to the Los Angeles County Sanitation District (LACSD)
District No. 5 and on to the Joint Water Pollution Control Plant (JWPCP) located in the City of
Carson. The Hyperion WWTP and JWPCP both provide secondary treatment prior to discharging
the effluent into the ocean. In addition, the WBMWD purchases approximately 9% of Hyperion's
secondary effluent for treatment at the ECLWRF to recycled water standards.
Upon collection of wastewater from the Cities of Los Angeles County, wastewater initially is sent
through bars and screens to remove large solids, such as branches, plastics and rags.
Wastewater is then sent to primary treatment. Primary treatment refers to the stage where
inorganic particles that could not be removed by the initial screening are removed. In this stage,
water is collected in long underground tanks that act similar to a river. Light materials will flow to
the top and heavier materials will sink to the bottom. Both the light and heavier materials can be
removed and are sent for disposal.
The primary treated water is then sent to the next stage: secondary treatment. Secondary
treatment acts as a biological treatment step to reproduce what naturally occurs in water treatment
in rivers. The same microorganisms that feed on dissolved organic particles during natural water
treatment are used in secondary treatment. Cryogenic oxygen from the air is supplied at a
concentration of 94% to create an ideal feeding environment for the microorganisms, decreasing
the overall time required for treatment. As the microorganisms complete the feeding process, they
sink to the bottom and are removed to be reused in another batch of wastewater. After secondary
treatment, the wastewater can be discharged to the ocean.
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
A portion of the secondary effluent produced at the Hyperion WWTP is purchased by WBMWD
and sent to ECLWRF where it can be treated further to recycled water standards. Here, the
wastewater undergoes tertiary treatment, a final stage where water is sent through filters to
remove any last suspended particles in the water. The filters contain layers of anthracite coal,
sand, and gravel. Once sent through the filters, the water is disinfected. Chlorine from the
disinfection process must be removed prior to use. Following the disinfection process and the
removal of excess chlorine, water is safe for use and is distributed to the customers of the
WBMWD reclaimed water system.
Approximately one-third of the wastewater collected by the LACSD sewer system and around 9%
of the Hyperion WWTP's effluent is treated to tertiary standards, as described above, and can be
used as recycled water. The remainder is treated to secondary standards at the JWPCP and
Hyperion WWTP before being disinfected and discharged into the ocean. None of the collected
wastewater is treated or disposed of within the City's service area.
The wastewater volume generated by the City for FY2019-2020 was estimated based on average
daily sewer generation rates as provided by the City. The rates collected by the City that are
treated at Hyperion WWTP are estimated based on metering and the estimate on JWPCP is
based on the estimate that half the wastewater is treated at each plant. The estimated wastewater
collected in FY 2019-2020 is provided in Table 6.5.1 on the following page.
No wastewater is treated and/or discharged within the service area.

Note: Corresponds to WUE Table 6-2R.
Recycled water is used at 63 sites within the City service area, with a total estimated demand of
approximately 9,164 AFY. The largest of these users of recycled water is the El Segundo Chevron
Refinery, which uses over 95% of the City's recycled water for irrigation, boiler feed water, cooling
towers, and its nitrification plant. The remainder of the recycled water use within the City is used
for irrigation of parks, medians, golf courses, etc. Recycled water users requiring more than 20
AFY are identified in Table 6.5.2. The current and projected recycled water direct beneficial uses
are listed in Table 6.5.3. In addition, Figure 6.5.1 shows a map of the recycled water service to

City of El Segundo — 2020 Urban Water Management Plan
The City does not have any plans to expand its current recycled water system. However, WBMWD
released a Capital Implementation Master Plan for Recycled Water Systems in 2009 that
identified potential expansions to its systems. Although this will not expand the City's recycled
water system, it will help increase reliability of both recycled and potable water service in the area,
and therefore is briefly discussed below.
The 2009 Master Plan identifies several improvements that can be made to expand WBMWD's
recycled water system. These are summarized in WBMWD's 2015 UWMP. Apart from increasing
reliability of the distribution system through repairs and corrosion protection, one major expansion
is planned that will indirectly help increase reliability to the City:
• Hyperion Secondary Effluent Pump Station Expansion: With the increasing demand on
ECLWRF, an increase for effluent from Hyperion WWTP is also needed. More secondary
treated wastewater is necessary to produce recycled water for injection into the West
Basin, as well as increased demands through other expansion projects. A pump station
expansion at Hyperion would be able to provide a capacity of up to 70 MGD for ECLWRF.
Although this project does not increase the supply to the City, it does increase the reliability
of supply by ensuring that ECLWRF will be able to produce enough recycled water for its
recycled water customers.
The City does not currently plan to expand recycled water use within its service area.
Table 6.5.4 compares the 2015 projected recycled water use for 2020 to the actual 2020 use.
Table 6.5.3 shows the current and projected recycled water uses within the City's service area. It
can be seen that the actual use for 2020 surpassed the projected use; however, this is due largely
to annual variation in use of recycled water at the Chevron Refinery.

NOTES: 2015 Projections for 2020 were calculated based on a combination of 2015 UWMP Tables 4.5.3 and 3.2.8.
The total recycled water uses from Table 3.2.8 were used in conjunction with the percentage of recycled water used
per customer in Table 4.5.3 to determine the projected recycled water use per Use Type for this table.
The City, WBMWD, and MWD encourage recycled water use among its customers. One of the
most compelling ways to encourage the use of recycled water is through the use of financial
incentives. Recycled water is available at anywhere from a 21-25% discount to customers who
use it over potable water. This allows financial savings while encouraging water conservation. In
addition, the WBMWD also encourages the use of recycled water by emphasizing the benefits of
recycled water to its customers. Among these benefits include the increased reliability and the
use of recycled water being consistent with the statewide goals for water conservation. WBMWD
notes that, even during a drought, wastewater will still be produced and must be treated to
recycled water standards.
WBMWD will also advance funds necessary for retrofitting existing potable connections for use
with recycled water. WBMWD realizes that the capital costs associated with this retrofitting may
be unavailable. To prevent this from hindering the use of recycled water at these sites, WBWMD
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
will retrofit the existing system and allow monthly reimbursement for advanced funds. Although
these incentives are available, currently there are no planned expansions for the City's recycled
water system.
In addition to the City and WBMWD incentives, MWD also has an extensive incentive program
for encouraging the use of recycled water among its member agencies. Please refer to the MWD
2020 UWMP update for more information.
The 2009 Capital Implementation Master Plan for Recycled Water Systems describes WBMWD's
plans to expand the recycled water system. However, the City does not anticipate expansions to
its own recycled water system. WBMWD is currently working on projects (e.g. the Hyperion
Secondary Effluent Pump Station Expansion projects described above) to increase the use and
reliability of recycled water within its service area.
Currently, the City does not have any planned projects that will diversify or expand the water
supply available to the City. The City has determined that pumping groundwater is not a viable
option for diversifying its water supply. Instead, the City anticipates that all potable water will be
provided through WBMWD, which has been determined to be high quality and reliable.
In the 2015 UWMP, WBMWD stated that it was diversifying its water sources to meet its target of
reducing imported water from the region through MWD by 17% within 20 years. This will be done
through the development of ocean water desalination and expanding its recycled water system.
For more information on how WBMWD plans to meet this target, refer to the WMBWD 2015
UWMP.

WATER SERVICE RELIABILITY
DROUGHT RISK ASSESSMENT
Currently, the only source of potable water that the City of El Segundo (City) utilizes is wholesale
distributed water through the West Basin Municipal Water District (WBMWD) which in turn is
provided through the Metropolitan Water District of Southern California (MWD) and the State
Water Project (SWP). Additional water supplies are obtained by treating wastewater and using it
as recycled water for irrigation purposes only. Although these sources are deemed reliable, each
has unique challenges to ensure that water will continue to be available. These challenges are
shown in Table 7.1.1 and described below.

West Basin Municipal Water District (WBMWD) Wholesale Water
WBMWD identified that its water supply to the City is considered reliable and sufficient to meet
demand. However, the reliability of the supply is dependent on the water quality delivered by the
SWP to MWD. In general, the SWP water quality has been acceptable, with delivered water
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
meeting State threshold requirements. However, as seawater intrusion in the Bay -Delta
increases, water quality can be diminished. In addition, as water moves through the Bay -Delta,
levels of total organic carbon and bromide are likely to increase. Water quality may also be
affected by the amount of wastewater that is disposed as this provides a means for the
transportation of salts and pathogens into clean water supplies. To prevent these water quality
issues from affecting the overall reliability of supply, WBMWD conducts water quality analyses
throughout the delivery process and at its water treatment plants to ensure water is safe prior to
delivery. Furthermore, State regulatory factors have included biological assessments affecting the
amount of water delivered from the Bay -Delta to the SWP system to prevent degradation of water
quality. MWD, WBMWD, and the City are diligent in identifying poor water quality and, in the event
of an observed water quality issue, will respond immediately to ensure substandard supplies are
treated properly and the clean source of potable water is restored. Please see Section 7.1.3 for
more information regarding water quality.
Recycled Water
Recycled water is treated by WBMWD to the tertiary level and as described in Chapter 6, the
supply is considered reliable. Similar to the City's potable water supply, water quality issues have
the potential to impact reliability and threaten the supply of recycled water.
The process of treating and distributing wastewater and recycled water can be hazardous due to
harmful bacteria and waste contaminants. As a result, the City must meet water quality standards
set forth by regulating agencies. These standards are prone to change as new issues develop. In
response to these changing standards, recycled water treatment plants must adapt to the
regulations and modify the process as necessary to ensure that water can continually be
delivered. The wastewater collection and recycled water distribution systems between the Los
Angeles County Sanitation District (LACSD), WBMWD, and the City ensure all aspects of
distributing safe and reliable recycled water are met and that high quality recycled water is
delivered to its customers for non -potable use. The LACSD and WBMWD are also receptive to
any changes that must be made in the treatment or distribution process to ensure compliance
with all water quality standards and that water is safe for irrigation use.
Water Quality
Each of the City's water sources present its own, unique water quality issues. Issues that may
cause concern regarding water quality are described in the subsections below. It should be noted
the MWD 2015 Annual Drinking Water Quality Report (covering the reporting period of January
through December 2014) did not identify any contaminant above the Maximum Contaminant Level
(MCL). The following subsections are presented, not to indicate they are the source of current
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
water quality violations in the City's water supply, but instead are identified as potential issues of
concern that should be monitored to ensure a high -quality water supply.
WBMWD Wholesale Water:
The water quality issues associated with the water supply to the City are the same as quality
issues experienced by WBMWD, and similar to those experienced by MWD. MWD has identified
threats to the water quality received through the Colorado River and the SWP. MWD reports that
increased salinity and chemicals (e.g. chromium VI, etc.) in the water it receives, in theory, could
cause at most a 15% reduction in supply. However, MWD also noted if concentrations of these
contaminants exceed the potable water quality threshold, tactics such as utilizing only small
amounts of the affected water and blending it with potable, processed water would reduce the
concentration to acceptable levels. MWD has stated that it "anticipates no significant reductions
in water supply availability [from the Colorado River, State Water Project, or local groundwater
sources] due to water quality."
The City realizes the importance of constantly ensuring the water it distributes meets potable
water standards. Although there are no water quality issues that immediately threaten the supply
to the City's customers, the City maintains knowledge of water quality issues to prevent poor
quality water from being distributed. The following subsections contain descriptions of the most
pertinent issues of concern.
Salinity
Increased salinity in the water received from the Colorado River has required MWD to, as
mentioned above, blend SWP water with Colorado River water to reduce the overall salt
concentration. While this issue has not caused water supply shortages, if salinity levels continue
to increase, additional membrane treatment of Colorado River water may be required. This will
slow the water purification process down and could result in a reduction of the water supply.
To prevent supply reduction, MWD has established a Salinity Management Policy, which aims to
reduce total dissolved solids (TDS) to less than 500 mg/L. Generally, only the water supply
delivered from the Colorado River has been found with unacceptable salinity levels. Water
delivered from the SWP has historically tested beneath the maximum contaminant level for
salinity.
Chromium VI (Hexavalent Chromium)
While currently there is no drinking water standard for Chromium VI, the California Office of
Environmental Health Hazard Assessment (OEHHA) established a draft Public Health Goal
(PHG) of 0.02 ppb (parts per billion) for Chromium VI in drinking water. However, the development
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
of the PHG is indicative of future potential standards for drinking water. MWD records of
Chromium VI content reveal that, if more stringent goals are implemented, additional treatment of
SWP water may be required as levels have historically been noted to exceed the proposed PHG.
The draft released by OEHHA on December 31, 2010, states that the PHG of 0.02 ppb is intended
to be a "stringent health -protective goal" as opposed to a "maximum `safe' level of Chromium VI
in drinking water."
In contrast to SWP, water from the Colorado River has historically been recorded as generally
having undetectable levels of Chromium VI.
Perchlorate
Another potential issue of concern for MWD is the contamination of perchlorate, a component in
solid rocket fuels, which has been detected in water from the Colorado River and its groundwater
sources. A chemical manufacturing facility owned by Tronox, Inc. in Henderson, NV was found to
be the source of the perchlorate contamination. It should be noted that Tronox is responsible for
perchlorate remediation at the site. In addition, perchlorate is present in the groundwater basins
in the Southern California area due to solid rocket fuels testing during the 1950's and 1960's.
Perchlorate contamination provides challenges due to the difficulty in removing it from water. As
a result additional treatment will always be required specifically for perchlorate.
Due to cleanup activities, MWD has reported a 90% reduction in perchlorate loading of Colorado
River water. Perchlorate concentrations are now recorded at less than 2 pg/L since 2006 which
is below the California Department of Public Health (CDPH) threshold of 6 pg/L. Furthermore,
Perchlorate has not been observed above contamination levels in the City.
In January 2011, the OEHHA released a draft PHG of 1 ppb, reduced from 6 ppb, for perchlorate
in drinking water, further emphasizing the importance treating the water contaminated with
perchlorates.
Table 7.1.2 indicates the potential impacts of water quality on the City's water supply, as identified
by WBM WD.
Recycled Water
In addition to affecting the potable water supply, similar water quality issues also affect the
recycled water supply. High levels of contaminants (e.g. TDS) in wastewater may require
additional treatment to ensure that safe and reliable recycled water is delivered to City end users.
Since recycled water is used primarily for industrial and irrigational purposes within the service
area of both the City and WBMWD, the effects of poor -quality recycled water would most likely
be observed in industrial equipment and crop and plant yields. High contamination levels in
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
industrial water could result in scaling and inefficiencies in the processes for which it is applied.
In addition, high levels of contamination in recycled water for irrigation can be harmful to plant life
and could prevent growth. If this were to occur, additional and more expensive wastewater
treatment may be necessary.
The LACSD and WBMWD do not anticipate any issues with recycled water quality. WBMWD
constantly monitors the water quality of recycled water sold to end users from its Edward C. Little
Water Recycling Facility to ensure that it meets all standards. Furthermore, the stringent salinity
requirements, and other water quality standards for potable water further reduces the likelihood
that poor quality recycled water will be delivered. The City does not anticipate having any issues
with recycled water quality that would be harmful, or in any way cause an increase in potable
water use
Table 7.1.2 indicates the potential impacts of water quality on the City's water supply, as identified
by WBMWD and the City.
Table 7.1.2: Water Quality - Current and Projected Water Supply Impacts
Prepared by: Risk Management Professionals, Inc.
As mentioned above, all potable water supplies are provided through WBMWD which is supplied
through MWD and the SWP. Since the supply is not directly obtained by the City, the
determination of reliability will largely be determined by WBMWD and MWD analyses to provide
a consistent water supply to the City during normal, single dry, and multiple dry years. Although
the City does not obtain its water directly from a natural source (e.g. groundwater or surface
water), it is committed to reducing water demand during times of drought in order to conserve
water and improve reliability for future water supplies.
For the purpose of this Plan, the Department of Water Resources defines average, single -dry,
and multiple dry years as follows.
Average Year: A year, or an averaged range of years, that most closely represents the median
water supply available to the agency.
Single -Dry Year: The year that represents the lowest water supply available to the agency.
Multiple Dry Years: The period that represents the lowest average water supply availability to
the agency for a consecutive multiple year period (three years or more).
Table 7.2.1 identifies the normal, single dry, and multiple dry water years chosen to represent the
water supply from WBMWD as well as the percentage/volume of supply that was available for
public use. These percentage values do not represent additional supplies through surplus
storage. Instead, they demonstrate the water available to be added to the supply system based
on the hydrology of those years.
Climate Change:
According to the California's Forth Climate Change Assessment, the City, and the greater Los
Angeles Area, should consider increases in temperature, reduction in precipitation, increased
fires, more frequent droughts, and changes in air quality, among others, as potential impacts of
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
climate change. Each of these impacts has the potential to develop into a water shortage scenario
for the community. While direct impacts to the City are vague based on current reports, the City
recognizes that continued efforts to increase water use efficiency are needed to mitigate the
impacts of climate change. The following tables demonstrate the reliable of the City' water supply
through multiple dry -year scenarios. It is likely, based on current information, that the likelihood
of these scenarios will increase in the future.

In the single dry water year, demand decreased due to implemented conservation measures. In
response, less water was supplied by WBMWD to meet the demand. Throughout multiple dry
years, the supply available from the WBMWD and MWD decreases due to ever diminishing
demands as the result of use reduction measures and public outreach. It was estimated in the
MWD 2020 UWMP that surplus supplies are available to meet demands during normal, dry, and
multiple dry year scenarios through 2040. Water use efficiency is dependent on the enactments
of the Water Shortage Contingency Plan. Through implementation of Plan and good coordination
with WBMWD, the City will continue to preserve the available water supplies and ensure
continued reliability for the future.

Tables 7.3.1 through 7.3.3, on the following pages, compare the total supply and demand as
identified in Chapters 5 and 6 for normal, single dry, and multiple dry years. It can be seen that
the supply available to the City, as provided in the WBMWD and MWD 2020 UWMPs, meets the
total demand for the single dry year scenario. During multiple dry year scenarios, the demand
exceeds the supply, however, WBMWD will be able to supply this difference. The City is
committed to water conservation in single dry and multiple dry years to help preserve water
reserves and supplies.
The data provided for the normal, single dry, and multiple dry year scenarios is provided in the
WBMWD 2020 UWMP. The plan identifies that during a single dry year scenario, demand may
decrease by approximately 8% over a normal year. WBMWD identified supply was sufficient in a
single dry year to meet this increased demand. During a multiple dry year, it was identified that
the demand may decrease by up to 24% in the fifth year. However, these demand decreases may
not actually be seen during multiple dry year scenarios due to the City's already low per capita
use leaving less room from use reduction than in the sample years. WBMWD did not identify any
reliability issues with delivering water during a single or multiple dry year period and identified that
supply would be sufficient to meet demand during a single dry year, while WBMWD will supply
the remaining amount necessary during the multiple dry year scenario.

The demand in a single dry year was estimated to increase by approximately 4%. During a single
dry year, the worst -case scenario of experiencing another severe drought would leave the City
adequate supplies, as WBMWD anticipates a 4% surplus during single dry years.

During a multiple dry year scenario with hydrology similar to that of 2007-2012, it is anticipated
that, based on the supplies outlined in Chapter 6 and the surplus identified in the WBMWD
UWMP, the City would be able to meet the demand. As stated above, the difference in estimated
supply and demand represents the estimated additional purchases from WBMWD. In addition, if
the City continues to implement water use reduction measures, the supply may be more than
sufficient to meet demands without additional water purchases.

Since all of the City's water supply (both potable and recycled) is provided by WBMWD, which in
turn is provided through MWD and the SWP, the reliability analysis for this water source will be
heavily dependent on the reliability analyses of these agencies. Although the City is dependent
on these sources to provide a reliable water supply, the City also works with WBMWD to ensure
water reliability in the future. The City has determined that using groundwater as a water source
is not ideal due to quality issues and the adjudication agreement that allows only minimal pumping
rights. Therefore, the City will continue to work with WBMWD to implement any necessary
improvements to ensure a reliable, high quality water source.
In accordance with the water code, the City has prepared a Drought Risk Assessment (DRA) in
accordance with the water code. The City estimated sufficient water supply should be available
to meet demands based on reported additional supplies from WBMWD through MWD and
anticipated water conservation efforts set forth in the Water Shortage Contingency Plan and City
Ordinances 1433 and 1437 for Water Conservation. The following section outline the specific
requirements of the water code and explain how the City meets compliance.
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
Data for the DRA was based on current and historic water demand records for the City and
estimated using the same tools used to complete the update to the Urban Water Management
Plan. The City population was estimated using linear percentage increases based on Department
of Finance E-1 projections between pillar years (2020-2025). Additionally, water supply was
calculated utilizing the same methodology used to determine the multiple dry year scenario.
Working with historical water supply values and then applying that percent to the current water
supply over successive years to develop a multiple dry -year scenario beginning in the current
planning year. The values reflect what supply and demand might look like if the City entered into
a multiple dry -year scenario beginning in the current year.
The following tables outline only the projected potable water supply and demand throughout the
drought scenario. These tables were developed utilizing DWR's Optional Planning Tool and
utilizes the methodologies included in the Urban Water Management Plan Guidebook.
As noted above, WBMWD has stated it can provide sufficient water for the foreseeable future
even in multiple dry -year conditions. So, for the purpose of these tables, and deficiencies were
met assuming supplemental water could be provided by WBMWD. While purchased water from
WBMWD is available to meet consumer demands, it is more economically sustainable for the City
to implement the water conservation measures outlined in City Ordinance 1050 and the WSCP
to avoid the need for supplemental water.

Table 4.1.1 illustrates gross and per capita water use for the City for many years including FY
2012-2017. These years framed a historic drought in California which inspired the changed to the
water code which necessitate the development of the DRA. During this period, the City
successfully supplied water to the community. This was achieved though significant
improvements in water conservation measures and public outreach. As the table demonstrates,
the City has continued to improve its water conservation efforts, easily surpassing water use goals
for 2020. With water usage per capita values continuing to improve and reliable supplemental
water from WBMWD at hand, the City is confident in its ability to continue to provide reliable water
service even if drought condition, such as the 2012 drought, were to reoccur.
At the time of this report, there are no recognized significant impacts due to climate change which
will impede the City's ability to provide water service. Furthermore, DWR efforts to improve water
use efficiency through reduced water losses will only improve resiliency as the City strives for
compliance.

8 WATER SHORTAGE CONTIGENCY PLAN
Currently, the only source of potable water that the City of El Segundo (City) utilizes is wholesale
water distributed through the West Basin Municipal Water District (WBMWD) which in turn is
provided through the Metropolitan Water District of Southern California (MWD) and the State
Water Project (SWP). Additional water supplies are obtained by treating wastewater and using it
as recycled water for irrigation purposes only.
Chapter 7 of the Urban Water Management Plan (UWMP) goes into detail about the anticipated
water supply and demand over the next twenty years. Based on projections from the WBMWD
UWMP, the water supply is considered to be reliable over the next twenty years in normal, dry,
and multiple -dry year scenarios. Below are the tables from Chapter 7 demonstrating the water
supply demand reliability estimates over the next twenty years.
Table 7.3.1: Supply and Demand Comparison — Normal Year

City of El Segundo — 2020 Urban Water Management Plan
WBMWD anticipated a supply that could exceed water demand in a multiple dry year period.
However, in stages of more sever water shortages, the City may ration supplies as necessary
and implement water conservation measures resulting in up to 50% water use reduction. This will
be implemented in situation when water supply is projected to reach dangerously low levels and
an emergency situation is imminent.
As a water supplier, the City must prepare an Annual Assessment. The Annual Assessment is a
determination of the near -term outlook for supplies and demands and how a perceived shortage
may relate to WSCP shortage stage response actions in the current calendar year; this
determination is based on known circumstances and information available to the City at the time
of the analysis. Starting in 2022, the Annual Assessment will be due by July 1 of every year, as
indicated by CWC Section 10632.1.
The Annual Assessment will be primarily based on the City's ongoing supply -demand tracking
process which is exhibited in monthly report by water personnel. These monthly analyses provide
key information for the City to manage resources to meet a range of estimated demands and
adjust to changing conditions throughout the year.
By June, City water personnel will present a completed Annual Assessment for approval to the
City Manager. This presentation will include a request that the approval of the Annual Assessment
determination also appropriately triggers any recommended specific shortage response actions
resulting from the assessment. Upon approval, City staff will then formally submit the Annual
Assessment to the Department of Water Resources (DWR) by July 1 each year.
Assessment Methodology
Because shortages are based on the difference between expected supplies and demand under
assumed current year and dry year conditions, the evaluation criteria to be used in the Annual
Assessment for determining a shortage include the following:
• Characterization of the current year and dry year scenarios bases on best -available data,
• Estimation of available core supplies, and
• Estimate of projected demands.
Together, these three criteria provide the necessary information to calculate shortage
percentages by dividing the difference between total core supplies and unconstrained demand by
total unconstrained demand, under current year and dry year scenarios.

City of El Segundo — 2020 Urban Water Management Plan
With population growth, energy shortages, earthquakes, and the threat of terrorism experienced
by California; maintaining the gentle balance between water supply and demand is a complicated
task that requires planning and forethought. In the event that a water shortage occurs, simple
measures can be implemented to conserve the water supply at a public level. Below, stages are
discussed during which various conservation measures will be imposed by the City of El Segundo,
beginning with voluntary conservation, and leading to various stages of mandatory compliance in
the event that the water supply experiences shortages of up to a 50 percent reduction in the water
supply. Implementation of the stages detailed below will occur on an emergency basis. Table
8.3.1 below provides an outline of each phase and the associated percentage of water supply
reduction.

Note: Coordinates with WUE table 8-1
Prepared by: Risk Management Professionals, Inc. I=
To prevent water waste and excessive consumption, the City has set in place Water Conservation
Ordinance No. 1433. The Water Conservation Ordinance outlines mandatory restrictions on water
use within the City, as described below in table 8.2.1.
The City has also adopted a Water Shortage Contingency Plan (WSCP) as part of its Municipal
Code. The WSCP describes the measures to take in the event of a water shortage, including
different stages of action corresponding to different levels of drought. As mentioned above, the
new Urban Water Management Plan regulation requires each agency to develop at WSCP with
six shortage levels. The existing WSCP has four stages of actions to take and several policies to
implement to minimize the impacts of water shortage, prepare for an increase in shortage, and
attempt to conserve water to prevent further shortage. The current WSCP is based on that
ordinance and seeks to expand on the polices included in it.
Table 8.2.1 on the following page provides an overview of the mandatory prohibitions and the
consumption reduction methods the City will implement to compensate in the event of a water
shortage.

Stage 1 Water Supply Shortage (01-10% voluntary reduction)
Unless another stage of water shortage is declared, the City will exist in a stage of constant
vigilance encouraging residence to voluntarily implement the reduction measures mentioned
above.
Stage 2 Water Supply Shortage (11-20% mandatory water conservation)
When the City declares a Stage I water supply shortage, it is because it anticipates that, due to
drought or other events, the City's water supply is uncertain. A Stage 1 Shortage calls for citizens
to voluntarily reduce water consumption by 15%.

• Irrigation of commercial nurseries, golf courses, or other water -dependent industries shall
be restricted to no more than twice during a seven-day period. The irrigation shall be
prohibited during the hours of 6:00 AM to 6:00 PM. There shall be no restriction on
watering with reclaimed water. Furthermore, this restriction does not apply to the watering
of plant materials classified as rare, exceptionally valuable, or essential to the wellbeing
of rare animals.
Stage 5 Water Supply Shortage (41-50% reduction)
In addition to the conservation requirements of a Stage 4 Water Supply Shortage, the following
water conservation mechanisms become mandatory when the City declares a Stage 5 Water
Supply Shortage:
• No person shall wash any motor vehicle, trailer, boat, or other type of mobile equipment,
except with a hand-held bucket or a hose equipped with a positive shutoff nozzle for quick
rinses. As an exception, washing is permitted at any time on the immediate premises of a
commercial car wash. Water used by all types of commercial car washing facilities, not
using partially reclaimed or recycled water, shall be reduced in volume by 50%. However,
washing where health, safety, and welfare of the public is contingent upon frequent vehicle
cleaning, such as garbage trucks and vehicles used to transport food and perishables, is
exempt from these regulations.
• Residential landscaping shall be restricted to watering only permanent trees and shrubs
with a hand carried bucket or drip irrigation system once during a seven day period during
the months of June, July, August, and September, and prohibited during the hours of 7:00
AM to 6:00 PM. Residential landscape irrigation shall be restricted to watering only
permanent trees and shrubs with a hand carried bucket or drip irrigation system once
during a fourteen day period during the months of October, November, December,
January, February, March, April, and May, and prohibited during the hours of 7:00 AM to
3:00 PM. This restriction does not apply to commercial nurseries, golf courses, and other
water -dependent industries.
• Irrigation of commercial nurseries, golf courses, or other water -dependent industries shall
be restricted to once during a seven day period and prohibited during the hours of 6:00
AM to 6:00 PM. There shall be no restriction on watering with reclaimed water. This

restriction does not apply to the watering of plant materials classified as rare, exceptionally
valuable, or essential to the wellbeing of rare animals.
• Filling or refilling swimming pools, spas, ponds, and artificial lakes is prohibited.
• No water shall be used for air conditioning purposes.
Stage 6 Water Supply Shortage (+51% reduction)
In addition to the conservation requirements of a Stage 5 Water Supply Shortage, the City Council
will provide additional water conservation measure based on the current drought situation. It is
assumed at this point; the City will declare a state or emergency and implement strict guidance
for water conservation to ensure base life support needs are met for the community.
Water Shortage Allocation
During advanced stages of water shortage, the City of places mandatory allocation constraints
requiring a percent consumption reduction. Individual allotments are based on a "basic use" as
administratively determined by the City Manager. Exceptions are made for residential customers
with 5/8", 3/4", or 1" meters which are not required to use less than a set daily equivalent per two
month billing period. Reductions for each stage are outlined below:
Stage 3: 20% reduction from the set allocation OR no more than the daily equivalent of 24 hundred
cubic feet (hcf) per two -month billing period,
Stage 4: 30% reduction from the set allocation OR no more than the daily equivalent of 21 hcf per
two -month billing period,
Stage 5: 50% reduction from the set allocation OR no more than the daily equivalent of 15 hcf per
two -month billing period.
Shortage Response Action Effectiveness
Efficacy of demand reduction efforts is difficult to estimate or predict, but water savings are a
function of the extent to which public information campaigns reach water users and the degree of
consumer response to those messages. Consistent with the Communications Plan in the following
section , anticipated shortages will involve an appropriately sized outreach campaign to address
the targeted demand reduction, which depends on the combined effectiveness of other shortage
response actions.
As shown in the following table, reduction responses are designed to reduce demands more than
50% of water demands. The WSCP contain six levels at which water reduction responses will be
applied to achieve appropriate levels of reduction. Table 8.2.2 gives examples of estimated
Prepared by: Risk Management Professionals, Inc. mis
City of El Segundo — 2020 Urban Water Management Plan
savings by each level using a hypothetical based on a demand of 5,468 AF. Actual reductions
and base demands are based on a formula that includes various factors such as actual local
supply production, population growth, and conservation.
Catastrophic Supply Interruptions
Potential causes for catastrophic failures that could put the water supply at risk include fires and
earthquakes. Both of these scenarios could potentially damage the infrastructure of the water
distribution system. In the event of a catastrophic event that prevents the City from obtaining water
for distribution, WBMWD implements actions and methods to continue supplying water to
customers of its member agencies. Water reserves are available to MWD through Diamond Lake,
as well as other surface reservoirs and it is estimated that MWD could provide full supply for up
to six months for all of its service areas following a catastrophic event. In addition, methods to
ensure that water is continually supplied to customers include stockpiling emergency pipeline
repair materials and coordinating with the California Governor's Office of Emergency Services
(Cal OES) and County's Operations Area in the event of a disruption in water supply.
Any effect felt by the WBMWD during a catastrophic event would impact the water supply to the
City as well. As a result, the City is subject to the actions and rationing of WBMWD. During any
kind of catastrophic event that disrupts the water supply, including a regional power outage or an
Prepared by: Risk Management Professionals, Inc. MID
City of El Segundo — 2020 Urban Water Management Plan
earthquake, the City, in conjunction with WBMWD and MWD, are prepared to continue providing
a reliable source of water.
Regional Power Outage
The City has identified the possibility of a regional power outage and its effect on the water supply.
Currently, the City Water Division does not have back-up generators. If a regional power outage
were to occur, then the two electric pumps would become disabled. However, the City has a
natural gas pump, which has a greater pumping capacity than both electric pumps combined. The
electric pumps operate at a maximum rate of 2000 gallons per minute (GPM), while the natural
gas pump operates at 5000 GPM. If a major earthquake or other catastrophic incident caused a
regional power outage and a natural gas line break, but the water distribution lines were still intact,
the City would be able to provide water to its customers and its emergency interties (i.e. City of
Los Angeles Department of Water & Power, City of Manhattan Beach, and the California Water
Service Company). Water Division operations personnel can change valve positions and directly
operate the water system from MWD's water pressure. The City is adequately prepared in the
event of a regional power outage.
In addition, to ensure the imported water supply is made available MWD has backup generation
at its facilities as well as the ability to employ gravitational flow from regional reservoirs such as
Lake Mathews, Castaic Lake, and Silverwood Lake. Mobile generators are also available as
needed.
Earthquake
In the event of a catastrophic earthquake, the City can coordinate with MWD and WBMWD to
ensure that any damaged lines are repaired as necessary to continue distributing water. In this
event, MWD would activate its Emergency Operation Center (EOC) to quickly respond to
emergencies and provide emergency services to its customers. The goal of the EOC is to identify
leaks and other weaknesses in the system following a catastrophic earthquake, and to quickly
isolate the problem in order to reduce wasted water and provide a potable water supply to the
population. In a worst -case scenario that caused the City's water reservoirs to rupture, water
service could continue by aligning the supply system so that it is supplied by MWD pressure.
With population growth, energy shortages, earthquakes, and the threat of terrorism experienced
by California; maintaining the gentle balance between water supply and demand is a complicated
task that requires planning and forethought. In the event that a water shortage occurs, simple
measures can be implemented to conserve the water supply at a public level. The stages in which
various conservation measures will be imposed by the City are laid out in Table 8.1.1.
Prepared by: Risk Management Professionals, Inc. MID
City of El Segundo — 2020 Urban Water Management Plan
Effectual reduction of water usage begins with effectual communication; both with the public and
heads of City management. Water personnel are responsible for communicating increasing water
shortage conditions and educating both the public and City management about the necessity and
way to conserve limited water supplies. In additional, Water personnel will collaborate with
CBMWD and the Metropolitan Water District to improve water reliably and infrastructure. Water
personnel will strive to;
• Motivate the public to:
o Increase conservation.
o Follow voluntary or mandatory water use guidelines.
o Participate in water -saving incentive programs.
• Raise awareness about:
o Water shortage and/or drought conditions
o Water sources, supplies, and reserves.
o Local, regional, and state regulations
• Educate the public about:
o Water supply reliability
o Water infrastructure and delivery
o Water quality
• Prepare City Management for:
o Varying water supply conditions
o Escalating supply shortage levels
Standard communication
Conservation as a way of life remains central to messaging during normal supply conditions.
Regional rebate programs, indoor and outdoor water use efficiency, investments to maintain
infrastructure, emergency preparedness, local supply programs, water quality, and regional
supply reliability are among some of the themes that make up normal supply period's
communications mix to encourage ongoing conservation actions. Below is a snapshot of the
various strategies involved:
• Social Media
• City Website
• Community Events
• Education Outreach
• Business Outreach
Prepared by: Risk Management Professionals, Inc. MID
City of El Segundo — 2020 Urban Water Management Plan
In the case of a water supply shortage, violators of the Mandatory Water Conservation Ordinance
and WSCP can face a maximum fine of $70 for a single violation. Table 8.3.1 describes the
penalties associated with single and recurring violations, which are outlined in the ordinance.
California Water Code Section 350 et seq. authorizes any public entity to declare a water shortage
emergency and, upon declaration of that emergency, adopt regulations and restrictions on the
delivery and consumption of water in order to conserve water resources during the period of the
emergency and until the supply of water available for distribution by the suppliers has been
replenished or augmented. For the City, the City Council, along with the City manager, has the
ability to declare a state of water shortage and enforce response actions appropriate to the
scenario. City Ordinance 1050 lays out the City's plan for implementing reduction measures
depending on the severity of the shortage. In 2020, the water code was updated mandating
additional water shortage levels be added through the development of this Water Shortage
Contingency Plan. This plan seeks to build off the existing ordinance, adding the additional
measures to meet Water Code 10635.

City of El Segundo — 2020 Urban Water Management Plan
During a water shortage, revenue is expected to decrease due to a reduction in water sales.
Furthermore, expenditures would be expected to increase due to the necessary marketing of
water conservation methods to reduce water use and potential increases in water purchased from
WBMWD. In the event that expenditures significantly outweigh revenue, the City has the authority
to increase water use rates or impose a water fee surcharge during times of drought. The results
of this would be two -fold: bringing in additional revenue with similar sales while simultaneously
discouraging water waste. The City also has a tiered rate structure for both potable and recycled
water use. Using this system, consumers rates increase with increased water consumption.
These options allow the City to respond quickly to funding issues accompanied with a drought
situation.
Furthermore, revenues can vary according to weather patterns and the availability of water
supplies. In dry years, local demands increase, and the City may receive higher than anticipated
revenues due to increased sales volumes. In contrast, in wet years, demands decrease, and
revenues drop due to lower sales volumes. Such revenue surpluses and shortages could cause
instability in water rates. To mitigate this risk, the City maintains financial reserves, with a
minimum and target balance, to stabilize water rates during times of reduced water sales. The
reserves hold revenues collected during times of high-water sales and are used to offset the need
for revenues during times of low sales. The City's practice of using reserves to buffer unexpected
increases or decreases in budgeted revenue also applies to unexpected expenditure increases
or decreases resulting from shortage responses.
Consistent with California Governor's Executive Order B-29-25, the City is currently monitoring
and comparing monthly consumption and production rates to the same months in 2013 in order
to determine levels of water usage reduction. These rates rely on groundwater pumping and water
purchase transaction records as well as end user meter readings to determine water quantities.
Should water shortage conditions remain, the City will continue to use these methods to document
and analyze measurable progress in water savings against previous years.
Prepared by: Risk Management Professionals, Inc. MID
City of El Segundo — 2020 Urban Water Management Plan
The WSCP will be periodically re-evaluated to ensure that its shortage risk tolerance is adequate,
and the shortage response actions are effective and up to date based on lessons learned from
implementing the WSCP. The WSCP will be revised and updated during the UWMP update cycle
to incorporate updated and new information. For example, actions that are no longer applicable
for reasons such as program expiration will be removed. However, if revisions to the WSCP are
warranted before the UWMP is updated, the WSCP will be updated outside of the UWMP update
cycle. In the course of preparing the Annual Assessment each year, City staff will routinely
consider the functionality the overall WSCP and will prepare recommendations for the City
Council if changes are found to be needed.
The City did not identify any special water features.
As was done for the 2020 Urban Water Management Plan update, the WSCP will be made
available during update years to the public and neighboring agencies. Drafts will be advertised on
the City website and by email to interested stakeholders. Each June, the City will hold a public
hearing to answer questions regarding the plan and for the City Council to approve the WSCP
prior to submission to the Department of Water Resources.

City of El Segundo — 2020 Urban Water Management Plan
The City adopted water conservation measures by Ordinance Numbers 1433 and 1437.
Ordinance No. 1433 added enforcement actions to the formerly adopted ordinance, and was
adopted on November 3, 2009. Ordinance No. 1437 addresses water conservation in
landscaping, and was adopted on December 15, 2009. To enforce these two ordinances, the City
will issue warnings and subsequent citations to customers exceeding the conservation
constraints.
In addition, a new Ordinance is under review to restrict the amout of water and sewer rates
pursuant to Health and Safety Code §5471 and the City's Municipal Code §11-1-5.
Metering with commodity rates by wholesale and retail agencies has been an industry standard;
it involves setting water rates based upon the external costs of importing water or producing water
from local sources, the internal costs of distribution and service, and establishing the sources for
financing or funding these costs. The City has meters in place for all of its customers, including
separate meters for single-family residential, multi -family residential, commercial, industrial, and
large landscape customer sectors. Water usage is billed based on volume of water consumed; in
addition, a fixed monthly or bi-monthly service fee based on meter size is billed separately. Hence,
the City utilizes commodity rates and has meters for all accounts since 1970.
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
The City currently has a tiered rate structure in place to encourage water conservation.
Additionally, the City has a service charge that is calculated by meter size and usage for all
customer sectors, which is billed either monthly or bi-monthly. The tiered water rates were
updated in the 2004 Ordinance 1376, which also states that potable water consumption charges
will be increased by the same percentage as WBMWD increases its charges to the City. The table
below shows the current rate structure; units are in dollars per hundred cubic feet ($/HCF).

The City utilizes several methods to promote water conservation and resource efficiency. The
following section discusses public outreach and education programs that the City utilizes.
Public Education and Outreach
The City promotes water conservation and resource efficiency in conjunction with WBMWD. The
City distributes public information through bill inserts, brochures, and many special events every
year. Additionally, the City established a website, which includes information on water
conservation, recycling, and other resource issues, which include the following initiatives.
• The City sends hotels a suggestion card template for them to make and place in rooms
and lobby describing water conservation for guests (sheets & towels).
• The City sends restaurants a suggestion table tent template for them to make and place
on tables describing water conservation for patrons (water glasses).
• Water conservation cards are printed and placed on city counters, as well as posted
reduction tips on walls/counters. Reduction tips and drought information are also provided
on the website under the water section, as well as being included in "latest news" section
on main page.
• Logos on the City's Facebook page have been added, where the City posts conservation
documentation and reduction tips.
• The City utilizes door hangers and water bill inserts in order to notify customers about
updated to water conservation information.
• Video segments are broadcasted on the City's TV Channel for conservation and reduction
clips, and videos are posted on the Water Bill website so users paying bills see it.
• Bus shelter advertisements and street banners are utilized throughout the City for
conservation efforts.
• The City also places links and/or images in email signatures from City employees.
• At Parks and Recreation events (e.g., farmer's market), booths, handouts, or signs are
present for public education.
• Information packages are also distributed to rotary/Kiwanis clubs.

On average, Water Division crews survey approximately 60 miles of main and lateral pipelines
per year. Line replacements are made based on a number of factors: a history of leaks in a
particular line over a number of years; flow, or lack thereof, as calculated by flow testing the line;
and sizing. If a leak is detected, City Water Division personnel repair the leak in a timely manner.

The City's water conservation coordinator is a function performed mainly by the Water Supervisor,
who maintains American Water Works Association (AWWA) conservation certification, working in
conjunction with WBMWD. The City stresses water conservation via distribution of conservation
handouts at City Hall and information booths at various community fairs. Historical and projected
expenditures are unavailable as the cost is included in the salary of each employee involved in
the program. The conservation coordinator also implements residential water audits at the request
of customers. Table 9.7.1 lists a historical summary for the City's Water Division personnel. All

The following subsections outline DMMs not categorized above.
Water Survey Programs for Residential Customers
The City, as a member of WBMWD, is eligible to receive support and funding for residential survey
devices. The City provided surveys up to 2010, and then opted to stop supporting this DMM.
Historical information on surveys may be provided in previous UWMP report from 2010.
Water Survey Programs for Commercial Customers
Water Use Surveys were conducted in 2015 to assess any improvement areas for water use by
commercial properties. Each facility was provide its own report summarizing the site description,
an evaluation of landscape water use, water use efficiency recommendations, and an irrigation
system inspection. Metrics on how much water and the cost savings (per year based on 2015
rates) are provided to each facility to demonstrate savings. Recommendations from these surveys
included any water saving equipment or landscaping changes (e.g., plumbing retrofits, drought -
tolerant plants, synthetic turf, etc.).
Residential Rebates
As a member of WBMWD, the City's residents are eligible for rebates on water conserving devices
for their residence. Qualifying items include retrofits, high -efficiency clothes washers, high -
efficiency toilets (HETs), weather -based irrigation controllers (WBICs), rotating sprinkler nozzles,
rain barrels, and soil moisture sensor systems. These water conservation rebate items are
discussed further below.
Residential Plumbing Retrofits
In conjunction with WBMWD, the City has participated in the distribution of showerheads,
aerators, toilet tank leak detection, and High -Efficiency Toilet (HET) replacement programs since
the 1990s. These conservation kits are distributed at the Water Yard and City Hall upon request.
The City emphasizes water use surveys and HET replacement programs. The kits are also
available to the City customers at WBMWD sponsored festivals and events described in the
WBMWD 2016 UWMP. These distributions are not recorded, and therefore, not quantifiable.
However, these events continue to provide the consumer with access to information regarding
available residential plumbing retrofits, as well as a variety of other water conservation materials
High -Efficiency Washing Machines
The City participates in a High -Efficiency Clothes Washer (HECW) Rebate Program as a member
of WBMWD. In 2003, WBMWD in conjunction with the Metropolitan Water District of Southern
Prepared by: Risk Management Professionals, Inc.
City of El Segundo — 2020 Urban Water Management Plan
California (MWD) collaborated on a program through California State and Federal Agency
Cooperation (CALFED), which offered rebates to residents who replaced their existing clothes
washer with a high efficiency model. This program offered an incentive of 100 dollars per rebate.
Prior to this program, the City participated in another incentive program, which offered similar
rebates; however, data for this previous program is unavailable. The program was so successful
that when the CALFED portion of the funding expired, MWD continued to provide funding at the
request of WBMWD and other member agencies. The new HECWs save 50 percent water,
60 percent electricity, and use less detergent. In 2004, the MWD Board with the support of
WBMWD, approved funding to continue the program through 2005. At the same time MWD
applied for Proposition 50 funding in an effort to continue the program for another several years.
Approximately 800 washing machine rebates were provided throughout WBMWD
High -Efficiency Toilets
In association with WBMWD, the City participates in an HET replacement program. Currently,
WBMWD offers rebates up to $50 per replacement. The City is committed to continually working
with WBMWD in this conservation effort. As advances in technology create new conservation
devices that are more efficient than today's products; the City and WBMWD plan on incorporating
them into this program.
Weather -Based Irrigation Controllers
Weather -Based Irrigation Controllers (WBICs) are programmable to use irrigation based on the
weather in the area. The United States Environmental Protection Agency (US EPA) has published
WaterSense® requirements for certification of devices/controllers. In general, all WaterSense®-
certified controllers must utilize evapotranspiration data from the site to regulate or adjust
irrigation. WBIC's are distributed for free through WBMWD.
Rain Barrels
Rain barrels collect rain water from the roof and/or gutters and diverts the water to a collection
basin (barrel). The water can later be used for irrigation by removing it from the barrel and
irrigating plants or lawn areas. Rain barrels are distributed for free through WBMWD. A total of
3,200 rain barrels have been provided by WBMWD, district -wide, since 2013.
Commercial, Industrial, and Institutional Programs
The City, in participation with WBMWD, promotes rebates to businesses, schools, and facilities
throughout its service area. Rebates are offered for commercial clothes washers, water brooms,
cooling tower conductivity controllers, pre -rinse spray nozzles, x-ray machine recirculation
devices, and commercial toilets and urinals.

Large Landscape Conservation Programs and Incentives
The City in conjunction with WBMWD offers programs to assist retail agencies and their large
landscape customers to use water efficiently. The programs offered are described below.
Irrigation Survey and Water Budget
The surveys are generally conducted by a team which calculates a water budget that identifies
the amount of water necessary for the site based on the size of the landscape and the climate.
The water budget would then be used as the water allotment for that site. During a drought, any
water use that exceeds the water budget is billed at a higher rate. However, most large landscape
areas within the City are already irrigated with reclaimed water.
Irrigation Controller Program
WBMWD has been working with the Project Advisory Committee (PAC) to develop a new WBIC
Program. The City recognizes the water savings potential, and as a member of WBMWD will
benefit from their current testing of weather -based irrigation controllers in sites that use potable
water. WBMWD plans to use the new controllers in areas where recycled water is inaccessible.
The funding incentives provided vary on the number of stations and acreage at each site. The
funding is used to help pay for the hardware and to help motivate involvement from the
community.
Ocean Friendly Gardens
In 2005, The City in conjunction with WBMWD formed a partnership with the Surfrider Foundation
to develop "Ocean Friendly Garden" workshops and demonstration gardens. WBMWD obtained
state grant funding to finance courses focusing on planting ocean friendly plants and installing
weather -based irrigation controllers as a way to reduce urban runoff. The use of water efficient
plants and installation of efficient sprinkler controllers can conserve between 20 percent and 50
percent of current water use and reduce water runoff by up to 70 percent. The City does not
record the attendance at these events, and therefore, this information is not quantifiable.

following:
(1) The waters of the state are a limited and renewable resource
subject to ever-increasing demands.
(2) The conservation and efficient use of urban water supplies are
of statewide concern; however, the planning for that use and the
implementation of those plans can best be accomplished at the local
level.
(3) A long-term, reliable supply of water is essential to protect
the productivity of California's businesses and economic climate.
(4) As part of its long-range planning activities, every urban
water supplier should make every effort to ensure the appropriate
level of reliability in its water service sufficient to meet the
needs of its various categories of customers during normal, dry, and
multiple dry water years.
(5) Public health issues have been raised over a number of
contaminants that have been identified in certain local and imported
water supplies.
(6) Implementing effective water management strategies, including
groundwater storage projects and recycled water projects, may require
specific water quality and salinity targets for meeting groundwater
basins water quality objectives and promoting beneficial use of
recycled water.
(7) Water quality regulations are becoming an increasingly
important factor in water agencies' selection of raw water sources,
treatment alternatives, and modifications to existing treatment
facilities.
(8) Changes in drinking water quality standards may also impact
the usefulness of water supplies and may ultimately impact supply
reliability.
(9) The quality of source supplies can have a significant impact

inclusion in the urban water supplier's plan that identifies and
quantifies, to the extent practicable, the existing and planned
sources of water as required by subdivision (b), available from the
wholesale agency to the urban water supplier over the same five-year
increments, and during various water -year types in accordance with
subdivision (c). An urban water supplier may rely upon water supply
information provided by the wholesale agency in fulfilling the plan
informational requirements of subdivisions (b) and (c).
10631.1. (a) The water use projections required by Section 10631
shall include projected water use for single-family and multifamily
residential housing needed for lower income households, as defined in
Section 50079.5 of the Health and Safety Code, as identified in the
housing element of any city, county, or city and county in the
service area of the supplier.
(b) It is the intent of the Legislature that the identification of
projected water use for single-family and multifamily residential
housing for lower income households will assist a supplier in
complying with the requirement under Section 65589.7 of the
Government Code to grant a priority for the provision of service to
housing units affordable to lower income households.
10631.5. (a) (1) Beginning January 1, 2009, the terms of, and
eligibility for, a water management grant or loan made to an urban
water supplier and awarded or administered by the department, state
board, or California Bay -Delta Authority or its successor agency
shall be conditioned on the implementation of the water demand
management measures described in Section 10631, as determined by the
department pursuant to subdivision (b).
(2) For the purposes of this section, water management grants and
loans include funding for programs and projects for surface water or
groundwater storage, recycling, desalination, water conservation,
water supply reliability, and water supply augmentation. This section
does not apply to water management projects funded by the federal
American Recovery and Reinvestment Act of 2009 (Public Law 111-5).
(3) Notwithstanding paragraph (1), the department shall determine
that an urban water supplier is eligible for a water management grant
or loan even though the supplier is not implementing all of the
water demand management measures described in Section 10631, if the
urban water supplier has submitted to the department for approval a
schedule, financing plan, and budget, to be included in the grant or
loan agreement, for implementation of the water demand management
measures. The supplier may request grant or loan funds to implement
the water demand management measures to the extent the request is
consistent with the eligibility requirements applicable to the water
management funds.
(4) (A) Notwithstanding paragraph (1), the department shall
California Urban Water Management Planning Act Page 7
2010
determine that an urban water supplier is eligible for a water
management grant or loan even though the supplier is not implementing
all of the water demand management measures described in Section
10631, if an urban water supplier submits to the department for
approval documentation demonstrating that a water demand management
measure is not locally cost effective. If the department determines
that the documentation submitted by the urban water supplier fails to
demonstrate that a water demand management measure is not locally
cost effective, the department shall notify the urban water supplier
and the agency administering the grant or loan program within 120
days that the documentation does not satisfy the requirements for an
exemption, and include in that notification a detailed statement to
support the determination.
(B) For purposes of this paragraph, "not locally cost effective"
means that the present value of the local benefits of implementing a
water demand management measure is less than the present value of the
local costs of implementing that measure.
(b) (1) The department, in consultation with the state board and
the California Bay -Delta Authority or its successor agency, and after
soliciting public comment regarding eligibility requirements, shall
develop eligibility requirements to implement the requirement of
paragraph (1) of subdivision (a). In establishing these eligibility
requirements, the department shall do both of the following:
(A) Consider the conservation measures described in the Memorandum
of Understanding Regarding Urban Water Conservation in California,
and alternative conservation approaches that provide equal or greater
water savings.
(B) Recognize the different legal, technical, fiscal, and
practical roles and responsibilities of wholesale water suppliers and
retail water suppliers.
(2) (A) For the purposes of this section, the department shall
determine whether an urban water supplier is implementing all of the
water demand management measures described in Section 10631 based on
either, or a combination, of the following:
(i) Compliance on an individual basis.
(ii) Compliance on a regional basis. Regional compliance shall
require participation in a regional conservation program consisting
of two or more urban water suppliers that achieves the level of
conservation or water efficiency savings equivalent to the amount of
conservation or savings achieved if each of the participating urban
water suppliers implemented the water demand management measures. The
urban water supplier administering the regional program shall
provide participating urban water suppliers and the department with
data to demonstrate that the regional program is consistent with this
clause. The department shall review the data to determine whether
the urban water suppliers in the regional program are meeting the
eligibility requirements.
(B) The department may require additional information for any
determination pursuant to this section.
(3) The department shall not deny eligibility to an urban water
supplier in compliance with the requirements of this section that is
participating in a multiagency water project, or an integrated
regional water management plan, developed pursuant to Section 75026
of the Public Resources Code, solely on the basis that one or more of
California Urban Water Management Planning Act Page 8
2010
the agencies participating in the project or plan is not
implementing all of the water demand management measures described in
Section 10631.
(c) In establishing guidelines pursuant to the specific funding
authorization for any water management grant or loan program subject
to this section, the agency administering the grant or loan program
shall include in the guidelines the eligibility requirements
developed by the department pursuant to subdivision (b).
(d) Upon receipt of a water management grant or loan application
by an agency administering a grant and loan program subject to this
section, the agency shall request an eligibility determination from
the department with respect to the requirements of this section. The
department shall respond to the request within 60 days of the
request.
(e) The urban water supplier may submit to the department copies
of its annual reports and other relevant documents to assist the
department in determining whether the urban water supplier is
implementing or scheduling the implementation of water demand
management activities. In addition, for urban water suppliers that
are signatories to the Memorandum of Understanding Regarding Urban
Water Conservation in California and submit biennial reports to the
California Urban Water Conservation Council in accordance with the
memorandum, the department may use these reports to assist in
tracking the implementation of water demand management measures.
(f) This section shall remain in effect only until July 1, 2016,
and as of that date is repealed, unless a later enacted statute, that
is enacted before July 1, 2016, deletes or extends that date.
10631.7. The department, in consultation with the California Urban
Water Conservation Council, shall convene an independent technical
panel to provide information and recommendations to the department
and the Legislature on new demand management measures, technologies,
and approaches. The panel shall consist of no more than seven
members, who shall be selected by the department to reflect a
balanced representation of experts. The panel shall have at least
one, but no more than two, representatives from each of the
following: retail water suppliers, environmental organizations, the
business community, wholesale water suppliers, and academia. The
panel shall be convened by January 1, 2009, and shall report to the
Legislature no later than January 1, 2010, and every five years
thereafter. The department shall review the panel report and include
in the final report to the Legislature the department's
recommendations and comments regarding the panel process and the
panel's recommendations.
10632. (a) The plan shall provide an urban water shortage
contingency analysis that includes each of the following elements
that are within the authority of the urban water supplier:
(1) Stages of action to be undertaken by the urban water supplier
in response to water supply shortages, including up to a 50 percent
reduction in water supply, and an outline of specific water supply
conditions that are applicable to each stage.
(2) An estimate of the minimum water supply available during each
of the next three water years based on the driest three-year historic
California Urban Water Management Planning Act Page 9
2010
sequence for the agency's water supply.
(3) 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.
(4) Additional, mandatory prohibitions against specific water use
practices during water shortages, including, but not limited to,
prohibiting the use of potable water for street cleaning.
(5) Consumption reduction methods in the most restrictive stages.
Each urban water supplier may use any type of consumption reduction
methods in its water shortage contingency analysis that would reduce
water use, are appropriate for its area, and have the ability to
achieve a water use reduction consistent with up to a 50 percent
reduction in water supply.
(6) Penalties or charges for excessive use, where applicable.
(7) An analysis of the impacts of each of the actions and
conditions described in paragraphs (1) to (6), inclusive, on the
revenues and expenditures of the urban water supplier, and proposed

T],i�e 9'3 ) 7020 is for the calculation of 2020 compliance only. All retail
suppliers must complete the SB X7-7 Compliance Form. Baseline and target calculations are
done in the SB X 7-7 Verification Form.
The SB X7-7 Verification Form is for the calculation of baselines and targets and is a separate
workbook from the SB X7-7 2020 Compliance Form. Most Suppliers will
have completed the SB X7-7 Verification Form with their 2015 UWMP and do not need to
complete this form again in 2020. See Chapter 5 Section 5.3 of the UWMP Guidebook for more
information regarding which Suppliers must, or may, complete the SB X7-7 Verification Form for
their 2020 UWMP. 2020 compliance calculations are done in the SB X7-7 2020 Compliance
Form.
The data from the tables below will not be entered into WUE Data Portal tables. These tables will be
submitted as separate uploads, in Excel, to WUE Data Portal.
Process Water Deduction
SB X7-7 tables 4-C, 4-C.1, 4-C.2, 4-C.3, 4-C.4 and 4-D
A supplier that will use the process water deduction will complete the appropriate tables in Excel,
submit them as a separate upload to the WUE Data Portal, and include them in its UWMP.
