Applicant Name: Western Municipal Water District 

Applicant City, County, State: Riverside, Riverside County, California 

Project Title: Recharging Recycled Water and Groundwater 

Desalter Expansion Feasibility Study (Project) 

Western Municipal Water District (Western Water), located in Southern California, will conduct a 

holistic water reuse study to increase local groundwater supplies and enhance water supply reliability 

to address the region’s concern with drought. The feasibility study will encompass various aspects in 

the reuse cycle, including exploring potential recycled water supplies, conveyance, and facilities to 

recharge the groundwater aquifer, expansion of a local groundwater desalter to pump the recharged 

water for treatment and potable supplies. Awarded funds will be used to support consultant work 

conducting the required groundwater modeling, water quality testing, Title 22 engineering reporting, 

and development of a final water recycling and desalination feasibility study meeting the 

requirements of United States Bureau of Reclamation Title XVI Water Reclamation and Reuse 

Program Feasibility Study Review Process (WTR 11-01). Water recycling and desalination are 

essential tools for stretching the limited water supplies in the Western United States. The benefits of 

this Project are to develop and supplement urban and irrigation water supplies through water 

reuse—thereby improving efficiency, providing flexibility during water shortages, diversifying the 

water supply, and optimizing water resource management. This project will provide Western Water’s 

growing community with new sources of clean water which enhances water management reliability 

and resiliency. 

The Project will take approximately 24 months to be completed, with an estimated completion date 

of October 31, 2025, (start date assumption of October 31, 2023). 

The proposed planning efforts do not involve a Federal facility or Federal land. 

PROJECT LOCATION 

Western Water is located in Riverside County, California, approximately 100 miles North of San 

Diego, approximately 75 miles east of the Pacific Ocean, and approximately 180 miles west of the 

Arizona border. The Recharging Recycled Water and Groundwater Desalter Expansion Feasibility 

Study Project (Project) will be developed for activities in the Riverside-Arlington Groundwater 

Subbasin. Figure 1 is a map of the geographic project location.

TECHNICAL PROJECT DESCRIPTION 

The Recycled Water and Groundwater Desalter Expansion Feasibility Study Project (Project) is 

seeking funding from Funding Group I. Western Municipal Water District (Western Water) is 

eligible to receive an award under Funding Group I because Western Water meets the eligibility 

criteria by being a water district located in California and can meet the non-federal cost share 

requirement of 50 percent or more of total project costs. 
Goals 

The long-term goals of this project are to 1) Groundwater Sustainability - meet environmental 

requirements to take currently available recycled water supplies and recharging it into the RiversideArlington Basin at the Victoria Recharge Basin; 2) Increasing Local Supplies - review of projects that 

can increase the amount of recycled water being recharged into the Riverside-Arlington groundwater 

basin; and 3) Create a Drought-Proof Supply - expanding existing desalter through consideration of 

groundwater basin health, production, end-user needs, and water quality and treatment needs. 

The objectives for the proposed activities are to develop a feasibility study that meets the 

requirements of the United States Bureau of Reclamation’s WTR 11-01. Western Water is planning 

to pursue one feasibility study that includes: 

• Feasibility for Increasing Recycled Water Supplies to Victoria Recharge Basin 

• Title 22 Engineering Report and environmental requirements for recharging 

current recycled water supplies coming from the Western Water Recycling 

Facility (WWRF- labeled "Recycled Water Connection" on Figure 1) 

• Feasibility for Arlington Desalter Expansion and Required Upgrades

EVALUATION CRITERIA 

Evaluation Criteria 1 – Project Planning and Analysis 

Subcriterion No.1a- Water Recycling Needs and Opportunities 

1. Describe the problems and needs in the project area. 

The Riverside-Arlington Basin (Basin) provides a critical source of local groundwater. However, 

recent drought conditions and increasing demands have impacted groundwater levels and storage 

volumes thereby making this source of water increasingly less reliable. Losing the reliability of this 

local groundwater supply creates water supply challenges and reduces Western Water’s resiliency to 

drought. 

To utilize Arlington Basin groundwater, Western Water operates the Arlington Desalter, a reverseosmosis groundwater treatment facility that began operation in 1990. The Arlington Desalter serves 

two purposes, providing a local source of potable water and decreasing subsurface outflow of lowquality groundwater to the Temescal Basin. 

Over the last 25 years, as seen in Figure 2, groundwater in storage in the Arlington Basin has 

declined by nearly 40 percent. These impacts have severely reduced the reliability of the Arlington 

Basin and created challenges for groundwater production from the Basin. For example, three of the 

five production wells are undergoing deepening of the bowls (i.e., the location where water is 

withdrawn in the well) to be able to pump more groundwater at the diminishing levels. As such, 

Western Water has been seeking additional options for increasing the availability and reliability of 

Basin water supplies in an effort to improve local water security and drought resiliency.

ARLINGTON BASIN WATER BUDGET (1961 - ·2011 

AND 2(112-2016) 

As identified in Western Water's 2022 Groundwater Sustainability Plan, more treated water cannot 

be produced without recharge. 

2. Describe the current and projected water supplies and demands in the project area; include a 

discussion on supply and demand imbalances. 

The Arlington Basin, located within the northern portion of Western Water’s wholesale service area, 

provides a critical local source of groundwater, making up approximately 69 percent of Western 

Water’s local supply and 7 percent of Western Water’s total supply. Western Water provides 

Arlington Basin water to the City of Norco and the City of Corona. The Arlington Basin 

groundwater makes up over 60 percent of the City of Norco supplies and a smaller portion of the 

City of Corona’s supplies. Western also can provide surplus groundwater supply from the Arlington 

Desalter to Western Water’s retail service area within the City of Riverside and greater Riverside 

County Area. Surplus groundwater supply could also be transported via an existing regional 

distribution system to Elsinore Valley Water District and Temescal Valley Water District. 

The historical water budget for Arlington basin was calculated in Western Water's Groundwater 

Sustainability Plan from 1966-2016. Historically, groundwater pumping made up 5,820 acre-feet per 

year (af/yr) of the total discharge from the groundwater basin. Underflow outflow to Temescal 

Basin makes up an average of 1,240 af/yr. The current water use for Arlington Basin was evaluated 

for the period from 2012 through 2016. Average groundwater pumping from all sources was 7,230 

af/yr. The Arlington Desalter pumps an average of 6,060 af/yr during that same period. Average 

Desalter usage is 50 percent larger than the historical average. This increase in local groundwater 

production is largely due to historic drought conditions from 2012 to 2016. The demand imbalances, 

outflows/inflows are described in the Groundwater Sustainability Plan and is shown in Figure 3. 

Figure 3: Arlington Basin Demand Imbalances 

9 
Future demands from this water source was calculated in the Groundwater Sustainability Plan based 

on long-term water supply planning by basin stakeholders. Section 0-6 in that document provides a 

discussion of potential Projects and Management Actions to achieve and maintain long-term stability 

of groundwater levels and water quality in the Arlington Basin. Proposed recharge activities at 

Victoria Recharge Basin were evaluated to support continued operation within the current 

sustainable yield of the groundwater basin and/or increase the sustainable yield through the addition 

of new water supplies. Initial modeling indicates that artificial recharge at Victoria Basin could 

provide the additional amount of groundwater necessary to make up the increase in demand. This 

study would allow us to determine how and where to take immediate action to address these needs. 

3. Describe how the planning activities will investigate potential uses and markets for reclaimed 

or desalinated water. 

The planning activities will investigate recycled water use in groundwater recharge. Then the Project 

will explore the feasibility of expanding the current Arlington Desalter system to increase local 

supplies. The current uses for the Arlington Desalter are for municipal, domestic, and industrial 

customers. Due to investments into regional connectivity, the Arlington Desalter system can provide 

local groundwater to 6 retail agencies ranging from the City of Jurupa to the City of Riverside and to 

Lake Elsinore. There is a market already for this desalinated water, so the feasibility study will review 

the needed recycled water for recharge to keep the basin sustainable, permitting requirements, and 

infrastructure required to maximize the groundwater supply. 

4. Describe the source water that will be considered for the project, including location, 

capacities, existing flows, treatment processes. 

The Project will analyze several source water options for recharge and its impact on groundwater 

quality and needed treatment for the proposed expansion. One source for water recharge will be 

available in the next three years. The Western Water Recycling Facility (WWRF), owned and 

operated by Western Water, receives the majority of its wastewater flow from the March Air Reserve 

Base (MARB) where over multiple decades, per- and polyfluoroalkyl substances (PFAS) have been 

routinely used in a wide array of applications. In recent years, there has been increasing evidence of 

substantial PFAS contamination from MARB with elevated concentrations detected in the 

wastewater system. Preliminary analyses performed in August 2019 have found PFAS 

concentrations in WWRF effluent to be exponentially higher than other wastewater treatment 

systems in the Santa Ana River watershed. See Figure 4. 

The recycled water produced at the WWRF is currently used for irrigation at the Golf Course and 

Riverside National Cemetery, and at residential and institutional facilities. The demand for recycled 

water is less than what is produced, so the recycled water gets transported to another wastewater 

treatment facility called Western Riverside County Regional Wastewater Authority (WRCWRA), is 

treated again, and then released to the Santa Ana River. Western Water wants to enable beneficial 

use of surplus recycled water to augment local groundwater supplies in the Arlington Basin. In order 

to take the recycled water and recharge it into the Victoria Basin, a facility located in the Arlington 

Basin, treatment is needed on the effluent at WWRF to treat for PFAS. The treatment project is 

currently in design and is outside the scope of this project. Western Water's Groundwater 

Sustainability Plan calculates additional groundwater recharge from WWRF at 340-1,280 afy. The 

Proposed Work under this plan will conduct the required environmental and modeling to develop

The feasibility study will also evaluate adding additional sources of recharge water such as recycled 

water from the City of Riverside’s wastewater treatment plant or other opportunities and required 

infrastructure to bring recycled water to the Victoria Recharge Basin. The feasibility study will also 

create scenarios for increased recharge and the increased available new water to extract through the 

existing Arlington Desalter system and review expansion scenarios and storage needs for the 

Arlington Desalter system to maximize the groundwater supplies, while keeping the basin 

sustainable.

Subcriterion No.1b- Evaluation of Project Alternatives 

1. Describe the objectives that all alternatives will be designed to meet. What other water 

supply alternatives and project alternatives will be investigated? 

The Planning study will develop and evaluate project alternatives listed below and as outlined In 

Task 5. Task 5 listed above details the Alternatives analysis that will be conducted and included in 

the feasibility study, which includes a "Statement of the specific objectives all alternatives, including 

the water reclamation, recycling or desalination project, are designed to address." The alternatives 

included will be based on the study’s findings, but may include: 

• Operate the Arlington Basin groundwater resources within sustainable yield 

• Cost per Acre-Foot of the project is equal to or less than the cost of imported water supplies 

11 
• Maximize production of local groundwater supplies 

• Maintain groundwater levels above the minimum threshold criteria calculated in the 

Groundwater Sustainability Plan 

• Operate the Arlington Basin at a steady rate, maximizing local storage 

• No change or improved quality of water in groundwater basin 

2. Describe how the planning activities will develop project alternatives (water supply sources, 

reuse strategies, or treatment technologies) that have been or will be investigated. 

The planning activities will review local recycled water availability from the other facilities such as 

the City of Riverside wastewater treatment plant and required infrastructure (piping, pump stations, 

and treatment needs) to move the identified local water to the Victoria Recharge Basin. The 

planning activities will also review the expansion of the Arlington Desalter system, through location 

of new wells, desalter train increases, and treatment technology needs. The Arlington Desalter 

currently uses reverse osmosis in its treatment. Granular Activated Carbon (GAC) treatment and the 

results from the WWRF PFAS design effort will also be investigated. The activity will also review 

brine line disposal projects and alternatives. 

3. Provide a general description of the selected project, including project features, benefits, 

anticipated costs, and analyses conducted. 

Task 5, described above, details the components to be included in the feasibility plan. Under the 

Alternatives section, an analysis will be completed for the proposed water recycling and desalination 

project including detailed project cost estimate; annual operation, maintenance, and replacement 

cost estimate; and life cycle costs. These costs shall be provided with sufficient detail to permit a 

more in-depth evaluation of the project, including non-construction costs. In this regard, the cost 

estimates shall clearly identify expenditures for major structures and facilities, as well as other types 

of construction and non-construction expenses and shall be based on calculated quantities and unit 

prices. The economic analysis included in the feasibility study report shall describe the conditions 

that exist in the area and provide projections of the future with, and without, the project. Emphasis 

in the analysis must be given to the contributions that the plan could make toward alleviation of 

economic problems and the meeting of future water demand. A cost comparison of alternatives that 

would satisfy the same demand as the proposed water recycling and desalination project will be 

developed. Alternatives used for comparison must be likely and realistic, and developed with the 

same standards with respect to interest rates and period of analysis. Additionally, the description of 

other water supply alternatives considered to accomplish the objectives, including benefits to be 

gained by each alternative, total project cost, life cycle cost, and corresponding cost of the project 

water produced expressed in dollars per MG, and/or dollars per acre-foot. An appraisal level cost 

estimates, or better, will be performed for these alternatives. Since this water recycling and 

desalination project will provide water supplies for municipal and industrial use, the benefits of the 

project can be measured in terms of the cost of the alternative most likely to be implemented in the 

absence of the project. Qualitative benefits will also be reviewed and included in the feasibility plan. 

4. Include a preliminary schedule showing major tasks, milestones, and dates for the planning, 

design, and construction activities related to the project. 

As described in Task 5, under Financial Capability of Sponsor, the feasibility study will provide a 

proposed schedule for implementation, with major tasks, milestones, and dates for planning, design, 

12 
and construction activities, as well as the willingness of Wester Water to pay for the identified 

project costs. 

Evaluation Criteria 2 – Stretching Water Supplies 

1. Describe the potential for the project to reduce, postpone, or eliminate the development of 

new or expanded non-recycled water supplies. 

The proposed Project will enable the use of already available recycled water to recharge the 

Arlington Basin to help maintain groundwater levels and improve long-term reliability of this local 

groundwater source. Improving and expanding local supplies is critical for maintaining a diverse 

water supply portfolio and creating drought resiliency. Currently, Western has 78,852 afy in available 

supplies to meet its retail and wholesale water demands. Over 65,000 afy, or 82.4% of this supply is 

imported water from the State Water Project and the Colorado River, supplies heavily impacted by 

drought resulting from climate change. 

Through Western Water's Drought Contingency Plan (DCP), adopted in 2022 and funded in part 

through the Bureau of Reclamation's Drought Contingency Planning grant, considerations of 

climate change impacts to water resources or drought was included (www.wmwd.com/uwmp). A 

vulnerability assessment was conducted through the development of the DCP (chapter 4). The 

vulnerability assessment performed aimed to improve the understanding of climate change impacts 

on future water demand in Western Water’s wholesale service area and the sources of Western 

Water’s supplies during normal and drought periods. The analysis identified that with future growth 

and without new local supplies being developed, an increase in imported water would be required. 

With concerns over declining groundwater levels, without recharging recycled water, the reliability of 

the local groundwater supply will decrease requiring more imported water to offset the loss of local 

supplies. This project will take nonbeneficially used recycled water and recharge it into the local 

groundwater basin, allowing for more local supplies to be produced, while maintaining the 

sustainability of the groundwater basin. 

2. Describe the potential for the project to alleviate pressure on existing water supplies and/or 

facilities. Please describe the existing water supplies, identify the supplies and/or facilities 

that will be impacted and explain how they will be impacted by the Project, including 

quantifications where applicable. 

The largest source of water for Western Water is imported water from Metropolitan Water District 

of Southern California (Metropolitan), which makes up approximately 60 percent of Western 

Water’s total supply. Of those supplies, about three quarters come from the State Water Project 

whose source is the Bay-Delta. The rest come from the Colorado River. The Delta is the largest 

wetland ecosystem on the Pacific Coast of the United States and provides habitat to highly diverse 

plant and animal life. Increasing local water supplies and reducing reliance on imported water 

through the implementation of this project will in turn reduce demands and impacts on the Delta’s 

ecosystem. 

The WWRF has a capacity to treat up to 3 mgd of wastewater to tertiary level, and flows have been 

in the range of 1.2 to 1.5 mgd. A portion of the existing supplies are utilized for irrigation and the 

remainder, 0.88 mgd are available for groundwater recharge. As effluent into WWRF reaches 

13 
capacity of 3 mgd, this could represent an additional supply of recycled water supply available for 

recharge. Once the Title 22 effort (Task 4) of the proposed project is completed, the recharge of the 

WWRF recycled water creates a new usable water supply available to augment local potable water 

supplies, offsetting imported water from the Colorado River and State Water Project. Any additional 

recharged water and expansion of the desalter system will alleviate pressure on the imported water 

system. 

3. Describe the potential for the project to make water available to address a specific concern. 

Explain the specific concern and its severity. Also explain the role of the project being 

investigated in addressing that concern and the extent to which the project will address it. 

Without the proposed project, and projects like it, Western Water and its retail and wholesale 

customers will experience growing challenges in fully meeting demands and maintaining sustainable 

groundwater levels, especially under drought conditions when imported water is less available. The 

majority of Western Water’s supplies comes from imported water purchased from Metropolitan 

Water District of Southern California. Those imported supplies are generally made up of about one 

quarter Colorado River Aqueduct supplies and about three quarters the State Water Project (SWP) 

supplies, from the Sacramento-San Joaquin Delta. Both of those sources experienced significant 

impacts during the recent multi-year drought resulting in curtailed deliveries and water supply 

shortages. This in turn increased the need for local water supplies. Without access to local supply, 

Western Water will either need more imported water or will have supply shortages, impacting water 

supply reliability. Groundwater is the primary local source of Western Water’s water supply, but 

those resources are also becoming increasingly stressed by drought. Over the last several years, the 

Arlington Basin has seen major groundwater depletion because of growing demands on 

groundwater resources under drought conditions (see Figure 2). Water quality is poor in the region, 

therefore there has been investments in desalting facilities. The Riverside-Arlington Basin has high 

nitrates and total dissolved solids (TDS) and the recycled water in the region has high levels of PFAS 

and other contaminants of emerging concern (CECs) 

With earthquakes and wildfires being a hazard in California, water conveyance infrastructures are at 

high-risk of damage. With most of the Western’s water travelling a long distance, over thousands of 

miles, the probability of an earthquake or damaging wildfire increases because we are not just 

looking at the probability of those events occurring in Riverside County, but throughout the state. 

Without this project, imported water supply will need to increase. If the Project maintains and 

increases local groundwater supply, the risk of natural disasters, such as earthquakes and wildfire, 

become more locally centered, therefore system reliability increases, and hazard risk reduces. 

The benefits of this additional water supply are substantial for the following reasons. By making new 

supply available, recharging the Arlington Basin, and expanding the desalter, this Project helps 

improve the long-term reliability of the Basin, as described by the Groundwater Sustainability Plan, 

and contributes to improved water supply reliability on a regional basis. By increasing recharge to 

the Arlington Basin, the Basin will continue to serve as a reliable local source of potable water and a 

continued supply source for Western which supplies water to 900,000 people across an area of 527 

square miles. The Basin groundwater makes up the majority of Western’s local water supply, at 69 

percent, and makes up over half of the City of Norco supplies. In addition, as noted above, 

improving local supplies is critical for maintaining a diverse water supply portfolio which helps 

14 
mitigate drought impacts and water shortages. The project’s contribution to improving long-term 

reliability of the Basin is critical to local water supply reliability and drought resilience across 

Western’s service area. The proposed project will propose projects that address water quality 

concerns in both recycled water and local groundwater to allow for high quality drinking water to be 

produced. 

Potential supply shortages under drought conditions could result in substantial economic burdens to 

customers due to each agency’s need to secure and pay higher costs for additional supplies. Since 

groundwater levels and sustainability of the basin are concerns that are monitored, without recharge, 

supplemental water from imported sources like Metropolitan, which can cost 40-50% more than 

local water, would be needed. Higher water supply costs have been, and in the future will be, passed 

on to the agency’s customers if local supply development does not occur, including the 

disadvantaged communities in the region. Therefore, increasing the availability of local groundwater 

would also contribute to reducing the economic burdens of water customers during droughts. 

Evaluation Criteria 3 – Environment and Water Quality 

1. Describe the potential for the project to improve the quality of surface water or 

groundwater. 

Part of the objectives of the Project and evaluation of Alternatives is to improve, or at least not 

change, the quality of the groundwater after the recycled water has been recharged. Projects that 

improve the quality of the groundwater will be reviewed and that benefit will be included in the 

analysis. Expanding the desalter will also improve groundwater quality by removing salt and other 

contaminants from the brackish water. 

2. Describe the potential for the project to improve effluent quality beyond levels necessary to 

meet State or Federal discharge requirements. 

The feasibility study will provide criteria required for discharge and water quality levels of the 

recycled water before it's discharged. This will allow for identification of new technologies and 

treatment to improve water quality levels beyond State and Federal discharge limits. 

3. Describe the potential for the project to improve flow conditions in a natural stream 

channel. 

Reducing the amount of water Western Water takes from the Delta allows water to stay in this vital 

ecosystem, where many of the aquatic species are endangered or threatened. This would improve 

flow conditions. Additionally, due to declining levels on the Colorado River and a call from the 

Bureau of Reclamation to reduce water consumption by 2-4 million acre-feet, reducing imported 

supplies directly helps flow conditions for that river system. 

4. Describe the potential for the project to restore or enhance habitat for non-listed fish and 

wildlife species. 

The Project will improve the reliability of groundwater for drinking water purposes and maximize 

the use of local water resources. As such, the Project once built will help Western avoid increased 

reliance on imported water supplies, which are primarily sourced from the Sacramento-San Joaquin 

Delta. By reducing the need for additional diversions from the Delta, the Project could indirectly 

contribute to improved conditions for fish and wildlife of that ecosystem, including the federally 

15 
endangered Delta Smelt. High water demands combined with changing environmental conditions 

are increasing stresses on the Delta ecosystem and threatening the wildlife and ecological functions 

associated with it. 

5. Describe the potential for the project to provide water or habitat for federally listed 

threatened or endangered species. 

Reducing the amount of water Western Water takes from the Delta allows water to stay in this vital 

ecosystem, where many of the aquatic species are endangered or threatened, including the federally 

endangered Delta Smelt, which is endemic to the upper Sacramento-San Joaquin Estuary that mainly 

inhabit the freshwater-saltwater mixing zone. With more freshwater being diverted to the State 

Water Project, the mixing zone becomes more brackish and further endangers the Delta Smelt, 

which causes a ripple effect on the ecosystem. Since the implementation of this project will reduce 

the amount of water exported from Northern California stream systems, there will be a positive 

benefit for the Sacramento–San Joaquin River Delta including the Delta Smelt and its critical habitat. 

With the 2017 wet year, the American Shad and the Striped Bass population increased, where the 

previous dry years had a negative impact on population. It is no question that extra fresh water in 

the Delta had a positive impact on the fish populations. Thus, the less water taken from the Delta 

during the wet and dry years is beneficial to the habitat and the species that inhabit the Delta. 

Evaluation Criteria 4 – Department of Interior Priorities 

1. Climate Change 

The largest source of water for Western Water is imported water from Metropolitan Water District 

of Southern California, which makes up approximately 60 percent of Western’s total supply. Of 

those supplies, about three quarters come from the State Water Project whose source is the BayDelta. The rest come from the Colorado River. The Delta is the largest wetland ecosystem on the 

Pacific Coast of the United States and provides habitat to highly diverse plant and animal life. 

Increasing local water supplies and reducing reliance on imported water through the implementation 

of this project will in turn reduce demands and impacts on the Delta’s ecosystem. 

With earthquakes and wildfires being a hazard in California, water conveyance infrastructures are at 

high-risk of damage. With a majority of Western’s water travelling a long distance, over thousands of 

miles, the probability of an earthquake or damaging wildfire increases because we are not just 

looking at the probability of those events occurring in Riverside County, but throughout the state. 

The odds of a natural hazard add together as one move over the distance. By being able to increase 

local groundwater supply, you could decrease your imported supply. Therefore, the risk of 

earthquakes and wildfire become more locally centered, therefore system reliability increases and 

hazard risk reduces. 

In addition, due to the water-energy nexus, reduced imported water will also result in reduced energy 

requirements and related emissions associated with source production, conveyance, and treatment 

requirements. Assuming the project will result in 985 afy less water diverted from the Delta and 

transported via the SWP to Western’s distribution system, the project’s infrastructure would result in 

annual energy savings of approximately 3,190,696 kWh. This is based on a study by the California 

Energy Commission (CEC 2005) that estimates that SWP East Branch water energy intensity is 

3,236 kWh/AF. 

16 
Another benefit, the proposed Project would recharge more water in Victoria Recharge Basin than 

what would be recharged through natural rainfall events. This would mean that more water will be in 

the basins, thus reducing the urban heat island effect during more months of the year. 

The proposed project could help mitigate water pollution. The WWRF receives most of its 

wastewater flow from the MARB where there has been application of PFAS, and where these 

chemicals have been found in the wastewater system. PFASs are man-made chemicals, which 

because of their incredibly unique water, oil, and flame-resistant properties, have been used in the 

past and currently used in many industrial processes and consumer products. They are persistent in 

the environment, are exceptionally mobile, and bioaccumulate, and therefore are a major human 

health and environmental concern. Apart from being potential carcinogens, these compounds are 

also linked to other human health issues, such as liver damage, kidney damage, increased cholesterol 

levels, pregnancy-induced hypertension, certain types of cancer and increased risk of thyroid disease, 

increased risk of decreased fertility, increased risk of asthma diagnosis, and decreased response to 

vaccines. Animal studies have also found that PFAS can cause damage to the liver and immune 

system. With PFAS in the water, in streambeds and other water sources, entire animal populations 

could be affected, especially those already exacerbated by climate change and drought. While there is 

no current State and Federal regulatory limits enforced for such chemicals yet, PFAS is an emerging 

contaminant of concern and a sensitive public relations/ awareness issue. Western Water has a 

project (outside the scope of this application) currently underway to treat PFAS out of the WWRF 

recycled water, allowing for better water quality to be recharged into the basin. The study will also 

analyze other recycled water sources and present any treatment requirements to ensure good quality 

water is being recharged into the basin. 

2. Disadvantaged or Underserved Communities 

This project will stabilize groundwater levels and allow for more clean, safe, affordable local 

groundwater supply to be provided to disadvantaged communities. Without the Project, more 

expensive imported water, which is also unreliable in a drought, will create an additional economic 

hardship for the local disadvantage communities. To address the cumulative effects of both 

pollution burden and socioeconomic stressors, and to identify which communities might need 

particular policy, investment, or programmatic interventions, the Office of Environmental Health 

Hazard Assessment (OEHHA) developed and now maintains and updates the CalEnviroScreen tool 

on behalf of CalEPA. The DWR DAC mapping tool is an interactive map that allows users to 

overlay the following US Census geographies as separate data layers: Census Place, Census Tract, 

and Census Block Group. Only those census geographies that meet the DAC definition are shown 

on the map [i.e., only those with an annual median household income (MHI) that is less than 80 

percent of the Statewide annual MHI (PRC Section 75005(g))]. Maps and Census Tract Analysis of 

the region of CalEnvironScreen and DWR’s DAC map have been provided in Attachment 3. 

Approximately 40% of the population that would directly be receiving the local groundwater is 

considered below 80% of the household median income (DWR DAC Map). Approximately 90% of 

the project area has a score 50 or higher on both pollution burden and population characteristics 

(CalEnvironScreen). Attachment 3 goes into more detail on what characteristics are impacting the 

CalEnviroScreen Score. The project’s benefit area ranks high (over 50%) on Poverty, Education, PM 

17 
2.5, Diesel particulate matter, traffic, Lead in housing, Groundwater threats, impaired water, and 

drinking water contaminates. 

3. Tribal Benefits 

Sherman Indian High School (SIHS), located in Riverside in the Riverside- Arlington Basin, is an 

off-reservation boarding high school for Native Americans. This high school is a groundwater 

pumper in the Arlington Basin. Through the proposed Project, recycled water will be treated with 

GAC and recharged in the Arlington Basin. This will increase water levels in the Basin and create 

more reliability for their existing wells. If the basin isn’t recharged or stabilized, the tribal high 

school may need to offset their supply with a more expensive, imported supply, which would make 

the tribal community less resilient to climate change or drought impacts. 

Evaluation Criteria 5 – Watershed Perspective 

1. Will the proposed project implement a regional or state water plan or an integrated resource 

management plan? Explain. 

The proposed project is included in three regional planning documents: 1) Groundwater 

Sustainability Plan; 2) Drought Contingency Plan; and 3) Urban Water Management Plan. 

Western Water believes in good basin management and made the decision to develop a 

Groundwater Sustainability Plan (GSP) that met the requirements of the Sustainable Groundwater 

Management Act (SGMA). The GSP considers scientific data and local knowledge of the basin and 

describes basin conditions, including the geology of the basin and groundwater levels within it. The 

Plan also establishes sustainability goals for the basin and outlines steps and potential management 

actions to ensure sustainability. The GSP can be found here (Arlington Basin Groundwater 

Sustainability Plan | Western Municipal Water District, CA (wmwd.com)). This project is listed in 

the GSP as recharge was identified as a required component of groundwater sustainability in the 

Riverside-Arlington basin. Therefore, this project recharging high-quality water to increase and 

stabilize groundwater levels directly implements the needs of the GSP. 

To increase water supply reliability and proactively address the region’s concern with drought, 

Western Water embarked on the preparation of a regional Drought Contingency Plan (DCP), 

funded in part by the United States Bureau of Reclamation (Reclamation). The DCP was adopted by 

Western Water’s Board of Directors on July 20, 2022. The DCP document can be found at 

www.wmwd.com/uwmp. Within the framework of a DCP, the project is listed as a mitigation 

action, which are generally developed in response to vulnerabilities identified through a Vulnerability 

Assessment. The vulnerability assessment found decreases in groundwater supplies due to water 

quality, increases in outdoor usage due to increases in evapotranspiration, thus there will be an 

increase in dependence on imported water if mitigation actions are not implemented. The proposed 

project will provide groundwater supplies that are resilient to drought and water quality concerns 

and will help increase water reliability in the region by decreasing the need for imported water 

supplies. Thus, the proposed project conducts feasibility on projects listed in the DCP. 

Western Water's 2020 Urban Water Management Plan (UWMP), adopted in 2021, considers 

drought’s impacts water supply and demand on a 25-year planning horizon. Western’s UWMP is a 

highly important water resources planning document which analyzes water supply reliability. The 

18 
analysis considers climate change and multi-year droughts to make projections on available future 

water supplies and potential future projects needed to improve supply reliability. The use of recycled 

water for recharge was identified a regional opportunity. 

2. Will the proposed project help meet the water supply needs of a large geographic area, 

region, or watershed? Explain. 

The proposed resiliency project meets the goals of the Groundwater Sustainability Plan and the 

Drought Contingency Plan. Recharge will be a required component of groundwater sustainability in 

the Arlington basin. Therefore, this project recharging high-quality water to increase and stabilize 

groundwater levels directly meets the goals of the GSP. One goal of the DCP is to utilize and 

maximize local water supply efforts. One of the types of feedback from the DCP stakeholder 

sessions was to get credit for all the past local efforts focused on recharge. This proposed Project 

does both. The proposed project will provide groundwater supplies that are resilient to drought and 

water quality concerns and will help increase water reliability in the region by decreasing the need for 

imported water supplies. 

The improved management of water supplies that this Project plans for is significant for Western 

Water’s overall water supply reliability and drought resiliency. Maintaining and enhancing a broad 

water supply portfolio is critical for addressing water supply challenges, including long-term drought, 

and in particular for a service area that meets the needs of 900,000 people. Effective water resource 

management depends on optimizing available resources and utilizing multiple sources. This Project 

achieves that goal by conducting a feasibility analysis on available recycled water to recharge into the 

Riverside-Arlington Basin for conjunctive use. Maintaining the reliability of this local groundwater 

source with available supplies is a critical management strategy to improve long-term reliability and 

water security in the region. 

3. Will the proposed project promote collaborative partnerships to address water-related 

issues? Explain. Describe stakeholder involvement in the project planning process. 

The proposed project stemmed from several collaborative planning partnerships to address waterrelated issues in the region. 

For development of the GSP, Western Water recruited basin stakeholders to participate in three 

workshops that informed the development of the GSP, sustainability goals, sustainable management 

criteria, and project analyses. 

For development of the DCP and UWMP, Western Water recruited, convened, and engaged a 

Drought Task Force comprised of 29 organizations represented by knowledgeable community 

leaders who can offer diverse, informed perspectives to support effective drought contingency 

planning. The members of the Drought Task Force organized by stakeholder segment group are 

presented in the DCP and UWMP. All retail water agencies in Western’s service area are represented 

on the Drought Task Force, including the agencies that can receive water from this project. The 

Drought Task Force participated in 5 interactive activities/meetings that aided in the collaborative 

development of the DCP. Specifically, the Drought Task Force informed the guiding principles and 

regional goals of the DCP, the development of the drought monitoring framework, feedback on the 

developed vulnerability assessment, each agency response actions from their WSCPs, and submitting 

19 
mitigation projects. Meeting summaries and recordings are posted on Western’s webpage. The 

proposed Project is listed in Western Water's DCP in the Mitigations Chapter (starting pg 107). 

During one of Western Water’s Drought Task Force interactive activities, Task Force members 

participated in a drought mitigation survey where all members had an opportunity to submit projects 

that would help their agency mitigate drought. In Western Water’s DCP, mitigation projects were 

categorized into 5 categories. The proposed projects align with the supply/treatment category, 

which focuses on creation of access to additional water supplies that leverages existing water supply 

sources, creates new sources of supply, and/or improves treatment capacity in existing plants to 

treat new, more challenging local water supplies. Projects were also evaluated by regional benefits. 

There are two large DCP regional benefits with 7 more specific benefits described in the DCP (pg. 

67). The proposed projects align with increasing local supplies, enhancing water supply reliability, 

enhancing operational flexibility, decreasing reliance on imported water supplies, benefiting 

disadvantaged communities, and promoting environmental justice. 

4. Will the proposed project include public outreach and opportunities for the public to learn 

about the project? Explain. 

As part of the Drought Monitoring Framework established by the DCP, the Drought Task Force 

will continue to meet and will be included in the planning process of this Project. The Project 

stemmed from a Reclamation funded activity, the DCP, and therefore moving forward with the 

project is a great example of interagency partnership. Western Water will outreach this project and 

Reclamation's support to the public via Town Hall discussions, Press Releases, FAQ sheets, and 

Social Media posts.

Re: Support for Western Municipal Water District’s Bureau of Reclamation’s WaterSMART: Water Recycling and 

Desalination Planning Grant Application 

Dear Commissioner Touton, 

I’m writing to you today in support of Western Municipal Water District’s (Western Water) application to the Water SMART: Water 

Recycling and Desalination Planning Funding Opportunity to implement the Recharging Recycled Water and Groundwater Desalter 

Expansion Feasibility Study Project (Project). 

Western is planning to produce one holistic feasibility study that includes determining the feasibility for increased recycled water 

supplies to Western’s recharge basins and the expansion of desalters, including water quality analysis for CECs (PFAS) and 

preparation of cost estimates and implementation schedules. 

Water recycling and desalination are essential tools used by Western Water for stretching the limited water supplies in their service 

area. Benefits of this Project will be to develop and supplement urban and irrigation water supplies through water reuse—thereby 

improving efficiency, providing flexibility during water shortages, and diversifying the water supply away from imported sources. 

These types of projects can provide growing communities with new sources of clean water which increases water management 

flexibility and overall, when implemented, will make Western Water’s service area’s water supply more reliable. 

Western Water’s Project is planning for a full circle feasibility study, one that taps into recycled water for recharge and then expands 

its desalter capacity to extract and treat the recharged water. Expanding the Arlington Desalter will develop and supplement 

municipal and irrigation water supplies through the treatment of brackish water, thereby increasing the region’s local supply, 

providing flexibility during water shortages, and diversifying the water supply portfolio. Western Water’s Project supports the 

priorities identified in Presidential Executive Order (E.O.) 14008: Tackling the Climate Crisis at Home and Abroad and align with 

other priorities, such as those identified in E.O. 13985: Advancing Racial Equity and Support for Underserved Communities Through 

the Federal Government. 

I represent the communities in Congress that are served by Western Water’s local desalter water and that would benefit from the 

project that will come out of the feasibility planning work proposed, and I am proud to support Western Water’s WaterSMART 

application for the Recharging Recycled Water and Groundwater Desalter Expansion Feasibility Study Project. 

Sincerely,

Re: Support for Western Municipal Water District's Bureau of Reclamation's WaterSMART: Water 

Recycling and Desalination Planning Grant Application 

Dear Mr. Miller: 

To facilitate project development under the Title XVI Program, the Desalination Construction Program, 

and the Large-Scale Water Recycling Program, the Bureau of Reclamation has funding available through 

the WaterSMART: Water Recycling and Desalination Planning funding opportunity for water recycling 

and desalination planning and pre-construction activities. Western Municipal Water District (Western 

Water) is applying to the WaterSMART program to implement the Recharging Recycled Water and 

Groundwater Desalter Expansion Feasibility Study Project (Project). 

Western is planning to pursue one feasibility study that includes: 

• 

• 

• 

• 

Feasibility for Increasing Recycled Water Supplies to Victoria Recharge Basin 

Feasibility for Arlington Desalter Expansion and Required Upgrades 

Feasibility and Water Quality Analysis for CECs (PFAS, etc.) 

Preparation of preliminary project cost estimates and schedules for possible future 

implementation 

Water recycling and desalination are essential tools for stretching the limited water supplies in the 

Western United States. Benefits of this Project is to develop and supplement urban and irrigation water 

supplies through water reuse-thereby improving efficiency, providing flexibility during water 

shortages, and diversifying the water supply. These types of projects provide growing communities with 

new sources of clean water which increases water management flexibility and overall when 

implemented will make Western Water's service area's water supply more reliable. 

Western Water's Project is planning for a full circle feasibility study, one that taps into recycled water for 

recharge and then expands its desalter capacity to extract and treat the recharged water. Expanding the 

Arlington Desalter will develop and supplement municipal and irrigation water supplies through the 

treatment of brackish water, thereby increasing the region's local supply, providing flexibility during 

water shortages, and diversifying the water supply portfolio. Western Water's Project supports the 

priorities identified in Presidential Executive Order (E.O.) 14008: Tackling the Climate Crisis at Home and 

Abroad and align with other priorities, such as those identified in E.O. 13985: Advancing Racial Equity

In Norco, we are extremely interested in seeing the further development of recycled water 

infrastructure in our region. As a partner with Western, we have previously developed a pump station 

that we hope to use to supply recycled water in Norco once further infrastructure can be completed. 

Similar projects in our area, such as this project proposed by Western, help build critical mass and show 

the business case for these types of projects for other agencies, such as the City of Norco. 

The City of Norco is a recipient of Western Water's local desalter water and would benefit from the 

project that will come out of the feasibility planning work proposed. The City of Norco is proud to 

support Western's Reclamation's WaterSMART: Water Recycling and Desalination Planning Grant 

Application for the Recharging Recycled Water and Groundwater Desalter Expansion Feasibility Study 

Project.

Dear Mr. Miller, 

To facilitate project development under the Title XVI Program, the Desalination Construction Program, and the LargeScale Water Recycling Program, The Bureau of Reclamation has funding available through the WaterSMART: Water 

Recycling and Desalination Planning funding opportunity for water recycling and desalination planning and preconstruction activities. Western Municipal Water District (Western Water) is applying to the WaterSMART program to 

implement the Recharging Recycled Water and Groundwater Desalter Expansion Feasibility Study Project (Project). 

Western is planning to pursue one feasibility study that includes: 

 Feasibility for Increasing Recycled Water Supplies to Victoria Recharge Basin 

 Feasibility for Arlington Desalter Expansion and Required Upgrades 

 Feasibility and Water Quality Analysis for CECs (PFAS, etc.) 

 Preparation of preliminary project cost estimates and schedules for possible future implementation 

Water recycling and desalination are essential tools for stretching the limited water supplies in the Western United States. 

Benefits of this Project is to develop and supplement urban and irrigation water supplies through water reuse—thereby 

improving efficiency, providing flexibility during water shortages, and diversifying the water supply. These types of projects

Dear Mr. Miller, 

On behalf of the Jurupa Community Services District (JCSD), I write in support of Western 

Municipal Water District’s (Western Water) Bureau of Reclamation’s WaterSMART: 

Water Recycling and Desalination Planning Grant Application. JCSD is a public agency 

providing services to over 130,000 people within the cities of Eastvale and Jurupa Valley. 

Established in 1956, our community services include water, wastewater, streetlights, 

graffiti abatement, and parks and recreation services. 

To facilitate project development under the Title XVI Program, the Desalination 

Construction Program, and the Large-Scale Water Recycling Program, The Bureau of 

Reclamation has funding available through the WaterSMART: Water Recycling and

As USBR is aware, JCSD is pursuing a similar recycled water project known as the Joint 

IEUA-JCSD Recycled Water Intertie Project. Upon completion, JCSD’s project will 

provide 3,160 acre-feet per year (AFY) of new recycled water to offset current potable 

water demands. Western Water and JCSD’s projects are critical to reducing imported 

water supplies, which benefit the imported water infrastructure managed by other regional 

agencies. 

JCSD is a strong collaborative partner with Western Water in securing water supplies for 

the region. As a result, JCSD is proud to support Western’s Reclamation’s WaterSMART: 

Water Recycling and Desalination Planning Grant Application for the Recharging 

Recycled Water and Groundwater Desalter Expansion Feasibility Study Project 

Thank you for considering JCSD’s support of Western Water’s application. If you need any

PROJECT BUDGET 

FUNDING PLAN 

The estimated total cost for the Project is $400,000. Western commits to providing up to $200,000 

in non-federal match funds in support of the activities identified in this proposal. It is expected that 

this amount will be satisfied by Western’s Operating Budget funded through water supply charges, 

property taxes, and fees on the wholesale delivery system. Funding from entities other than 

Reclamation will not be requested. The budget proposal does not include design or other project 

costs that will be incurred prior to Project award.

Salaries and Wages 

Most of the project work will be conducted by specialized contractors. For this reason, Western 

Water will not be seeking reimbursement for staff time spent on the project. 

Fringe Benefits 

Fringe benefits are not included in the overall project budget. 

Travel 

No reimbursement or match for staff travel is being sought. It is not anticipated that there will be 

travel required by the consultant/contractor. However, if there is, those costs would be captured 

within the “contractual” budget category with any consultant/contractor cost estimates. These costs 

would be marked as ineligible, following the guidance from the Notice of Funding Opportunity. 

Equipment 

Any equipment will be provided by the selected vendor. 

Supplies 

All materials and supplies will be purchased by the selected vendor. 

4 
Contractual 

The estimated contractual work is based on Western’s historical experiences doing similar-natured 

feasibility studies. One contractor will be selected through Western’s procurement procedures. 

Western staff have no concerns that there will be large changes to the budget and believes that if 

awarded, any changes will not result in the Project costs paid by Western becoming less than 50%. 

Construction 

No construction work is part of the Project. 

Environmental and Cultural Resources Compliance 

“Environmental compliance costs” refer to costs incurred by Reclamation or the recipient in 

complying with environmental and cultural regulations applicable to this grant, including costs 

associated with any required documentation of environmental compliance and cultural analyses, 

permits, or approvals. A 2% estimate from total project costs was used to calculate potential 

environmental compliance costs. 

Other Expenses 

No other expenses are included in the budget. 

Indirect Costs 

No indirect costs are included in the budget. 

LETTERS OF COMMITMENT 

No letters of commitment are required for this application. Western Water's Board of Directors 

have agreed to the cost-match obligations of the submitted proposal.

Disadvantaged Communities 

CalEnviroScreen 4.0 

In order to address the cumulative effects of both pollution burden and socioeconomic 

stressors, and to identify which communities might be in need of particular policy, investment, 

or programmatic interventions, the Office of Environmental Health Hazard Assessment 

(OEHHA) developed and now maintains and updates the CalEnviroScreen tool on behalf of 

CalEPA. Appendix # provides the draft report on the CalEnviroScreen tool. The tool indicates 

how disadvantaged a community is through a score of 1-100 (CalEnviroScreen 4.0 | OEHHA). 

The higher the score, the more disadvantaged a community is.
