SUMMARY 

DATE: February 28, 2023 

APPLICANT NAME: City of Los Angeles

CITY/ COUNTY: Los Angeles, Los Angeles 

County 

STATE: California 

APPLICANT CATEGORY: Funding Group II 

The City of Los Angeles (City) is planning to 

implement a city-wide integrated water resources 

strategy, the Hyperion 2035 Program. The goal is 

to provide a new, local reliable water supply 

source (up to 243,232 acre feet per year [AFY] or 

approximately 45 percent of the City’s demand) to 

sustain the long-term reliability of local 

groundwater basins, build water supply resiliency, 

diversify the City’s water portfolio, and decrease 

the region’s dependence on imported water. The 

Hyperion 2035 Phase 1 Project (Phase 1 

Project), with a total project cost of $1.4 

billion, is the first phase of the project and 

implements critical infrastructure to deliver 

56,044 AFY (50 MGD) of Indirect Potable 

Reuse (IPR) water to the West Coast Barrier, 

Central Basin and new users. The Phase 1 

Project consists of five main components: (1) 

enabling primary effluent conveyance modification 

projects; (2) conversion of secondary treatment to 

MBR including nitrification/denitrification; 

(3) construction of Advanced Water Purification 

Facility (AWPF) at Hyperion Water Reclamation 

Plant (HWRP) to produce 56,044 AFY; (4) 

modifications to the West Basin Municipal Water 

District (WBMWD) pump station for recycled water 

deliveries; and (5) sidestream treatment facility to 

enhance the secondary treatment. The Phase 1 

Project, the first of its size in the nation in terms of 

Fgure ES- 1: Map of Hyperion Phase 1 Project with HWRP and 

identifed IPR recharge alternatives 

magnitude and regional reach, benefts the region 

by diversifying the City’s water supply portfolio by 

adding recycled water, while modernizing HWRP 

and reducing efuent discharges to Santa Monica 

Bay. Los Angeles Sanitation and Environment 

(LASAN) is requesting funding for the planning/ 

preliminary engineering activities (including a 

Reclamation Feasibility Study) required to move 

the Phase 1 Project forward into construction and 

align the program to pursue future federal funding 

opportunities. The total costs to be expended 

by LASAN during the funding period, 

October 31, 2023 (anticipated award date) 

and before October 31, 2025, on planning 

activities for the Hyperion 2035 Phase 1 

Project is $21,415,458. LASAN is requesting 

Reclamation funding of $5,000,000. The 

project will not involve a federal facility or be on 

federal land.

PROJECT 

DESCRIPTION 

APPLICANT CATEGORY Funding Group II. The 

total planning costs to be expended for the Phase 

1 Project during the funding period, October 31, 

2023 through October 31, 2025, is $21,415,458. 

ELIGIBILITY OF APPLICANT LASAN, a bureau 

of the Department of Public Works, is the sanitation 

agency and owner of HWRP. The Phase 1 Project 

is a collaboration of LASAN with the Los Angeles 

Department of Water and Power (LADWP), which 

has water and power delivery authority in the City. 

PROJECT OVERVIEW, 

BACKGROUND AND GOALS 

Los Angeles (City) is the most populous city of 

California (population 3.9 million people [2020 

Census]) and the second most populous city in 

the United States. The City is primarily reliant on 

imported water supplies (California State Water 

Project [SWP], Los Angeles Aqueduct [LAA] and 

Colorado River Aqueduct [CRA] with limited 

local water [groundwater, stormwater capture, 

conservation and water recycling]). 

The Phase 1 Project, is a collaboration of LASAN 

with LADWP, with LASAN responsible for the 

production of recycled water and LADWP for 

its delivery to identifed users/uses. LADWP 

provides approximately 512,504 AFY of water to 

its customers. LASAN, responsible for the City’s 

wastewater collection and treatment systems, 

operates four water reclamation plants (WRPs) and 

6,700 miles of sewers. 

Imported water supplies, providing up to 

90 percent of the City’s potable water demand, 

are highly vulnerable to cutbacks from droughts, 

environmental demands, natural disasters and 

infrastructure failures. Local groundwater and 

2 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

stormwater sources are also highly susceptible 

to drought and legacy contaminants, which 

limit direct use. Social and economic impacts 

associated with the City’s water supply challenges 

include limited supplies to meet demands, 

increased cost of living, fre hazards, natural 

disasters, and rising imported water cost. 

The City’s Green New Deal, Sustainability Plan 

2019 establishes long-term goals to reduce 

imported water use, increase local water supplies 

and diversify its water portfolio to enhance longterm reliability and climate-change resiliency. 

Potable reuse was identifed as a major local 

supply that could provide up to 50 percent of the 

total potable water demand. 

City’s planning studies have documented that 

the greatest potential resides at HWRP, which 

treats 84 percent of the City’s wastewater fows 

that are predominantly discharged to the Pacifc 

Ocean. Based on fow projections for 2050, LASAN 

identifed the availability of 272 MGD of fows for 

potable reuse using indirect potable reuse (IPR) 

for groundwater augmentation or direct potable 

reuse (DPR) with raw water augmentation with the 

City’s potable water system. 

The centralized nature of the HWRP, along 

with its size and proximity to the Pacifc Ocean, 

provides an opportunity for the City to implement 

a large-scale recycled water project while 

leveraging economies of scale for an efcient, 

environmentally sound and cost-efective 

operation that maximizes existing infrastructure. 

The City developed the Hyperion 2035 Program 

to provide a new, local reliable water supply 

source to sustain the long-term reliability of 

local groundwater basins, build water supply 

resiliency, diversify the City’s water supply 

portfolio, and decrease the region’s dependence 

on imported water. 

The Hyperion 2035 Phase 1 Project implements 

critical infrastructure at the HWRP to establish 

the advanced treatment capacity needed to 

support the larger program and will produce a 

minimum of 56,044 AFY of IPR quality water upon 

construction. Project components include the 

conversion of secondary facilities to membrane 

bioreactor facilities (MBR), addition of AWPF 

(reverse osmosis [RO] and ultraviolet advanced 

oxidation process [UV AOP]), efuent pump 

station modifcation, and several enabling 

projects including a new intermediate pump 

station, diurnal equalization, and a sidestream 

treatment facility. 

Project Goals: 

The Hyperion 2035 Phase 1 Project goals include: 

 Advance the policy goals of the City’s Green 

New Deal, Sustainability Plan to increase 

the development of local water supplies and 

reduce dependence on imported water. 

 Develop 56,044 AFY of new recycled water 

supply for immediate application. 

 Modernize HWRP infrastructure to support the 

long-term resiliency of the facility. 

 Leverage existing conveyance and storage 

systems to efciently and cost-efectively 

distribute recycled water for benefcial reuse 

in the City. 

 Collaboratively develop a regional recycled 

water system to holistically increase benefcial 

use of available local water supplies and 

storage capacity. 

 Create an integrated water strategy that 

improves water security and resiliency in a costefective, environmentally sound manner to 

address the efects of climate change. 

Project Benefts: 

The Phase 1 Project provides social, economic 

and environmental benefts to the region. 

Benefts include conformance with current 

and future regulatory standards, water quality 

and environmental benefts, water portfolio 

augmentation and diversifcation, operational

fexibility to address drought and climate change, 

cost efective solutions for water supply reliability, 

and local business and workforce development. 

City incentives encourage women, small and/or 

minority-owned businesses to compete for City 

contracting opportunities, including those for the 

Phase 1 Project. 

Project Approach 

The City and LASAN have made a signifcant 

investment in the development of the Phase 1 

Project. Additional planning studies need to be 

completed to advance the Phase 1 Project from 

its current planning stage to 10 percent design 

and to procure a Progressive-Design Build 

contractor to complete construction of the Phase 1 

Project by 2032. 

Phase I Project planning activities include: 

Technical Studies: To date, LASAN and LADWP 

have completed planning studies that identify 

available water supplies and demands, water 

supply sources, project alternatives, and potential 

reuse opportunities. Additional technical and 

environmental studies to be completed include: 

 Evaluation of reverse osmosis concentrate 

(ROC) fow management options in relation 

to impacts on Santa Monica Bay and NPDES 

Permit compliance (Santa Monica Bay PCB 

TMDL; and dilution factors for ROC discharges). 

 Evaluation of nutrient management options and 

anticipated reductions in nutrient loading and 

associated impacts on coast water quality. 

 Evaluations of Contaminants of Emerging 

Concern (CECs) in wastewater produced during 

advanced water purifcation, and in ROC. 

Completion of these technical studies will 

address and help remove institutional and 

public perception barriers to IPR/DPR. 

Refinement of Alternatives Analyses: LASAN 

will review alternatives, identify new project 

concepts and fnalize the preferred treatment/ 

reuse alternative for design and construction: 

 Review and evaluate treatment alternatives at 

HWRP identifed by LASAN, LADWP, Technical 

Advisory Committee members, or others. 

 Conduct joint technical planning meetings with 

LADWP to review proposed concepts. 

 Review and evaluate reuse market/alternatives 

and identify fnal uses for Phase 1 Project 

(LASAN, LADWP, TAC, or others). 

 Confrm preferred treatment 

alternative at HWRP. 

 Review capital, O&M and lifecycle costs and 

evaluate cost savings/impacts. 

Refnement of the Alternatives Analysis enables 

LASAN to confrm the optimal cost-efective 

treatment alternative to be carried forward in 

the Concept Design Report. 

Facility Master Plan: The above tasks will 

provide the basis for a comprehensive facility 

master plan (“Program Implementation Plan”[PIP]) 

that will include: 

 Development design criteria, hydraulic profle, 

process fow diagrams, key facility layouts, 

major equipment schedule and estimated 

electrical loads. 

 Weekly meetings to facilitate review, and 

decisions on the above deliverables. 

 Development of 3D models in SketchUp or 

other 3D tool. 

 Constructability, risk, and gap analyses. 

 Preliminary site investigations (e.g. surveying, 

geotechnical investigation, other) 

PIP will delineate the technical elements of the 

Phase 1 Project and its subsequent phases to 

ensure proper integration and sequencing.

the Phase 1 Project. 

 Technical Requirements including project 

setting, applicable codes/ standards and 

preliminary design criteria for all major 

components of the Phase 1 Project. 

 Opinion of Probable Cost of Construction. 

 Draft and Final Concept Design Report. 

Development of Concept Design Report enables 

LASAN to move towards PDB Contractor 

Procurement and establishes the basis of 

design of the fnal Phase 1 Project. 

Inter-agency coordination and public 

engagement: This task implements public 

involvement activities to inform stakeholders of 

the alternatives and project progress, obtain input 

on the fnal project scope and garner support for 

the project. Activities include: 

 Monthly meetings with LADWP to discuss 

management, technical aspects of the project. 

 Quarterly regional meetings with key 

regional partners. 

 Technical Advisory Group (TAG) and Community 

Advisory Group (CAG) meetings to provide 

briefngs to and solicit input from industry 

experts, community representatives, elected 

and appointed ofcials, and non-governmental 

organizations. 

 Development of educational content (e.g. 

mailers, factsheets), website updates, and 

educational events at HWRP or other venues to 

promote public education. 

Enhanced inter-agency coordination and public 

engagement activities help address potential 

institutional issues during project development. 

Environmental Planning: LASAN and 

LADWP are jointly developing a Programmatic 

Environmental Impact Report (PEIR) for the overall 

Hyperion 2035 program. The PEIR will also cover 

the Phase 1 Project at a project-specifc level. 

Funding for this task will be utilized to: 

 Develop the Phase 1 Project description for the 

CEQA/ NEPA and permit documentation. 

 Develop the Environmental Impact Study (EIS) 

for the Phase 1 Project. 

 Develop a Permitting Plan identifying federal, 

state and local permits and approvals required 

to implement the Phase 1 Project. 

Completion of the proposed Environmental 

Planning activities enable LASAN to address 

environmental compliance requirements and 

move the project towards construction. 

Reclamation Feasibility Study. LASAN will 

develop a Bureau of Reclamation Feasibility Study, 

in accordance with WTR 11-01 and TRMR-128 for 

the Phase 1 Project. LASAN will develop a draft 

and fnal report summarizing: water reclamation 

and recycling opportunities; recycled water uses 

including a recycled water market analysis, source 

waters, and existing recycled water facilities and 

disposal options; Project Alternatives; Economic 

and Financial Analysis; Recommended Project; 

and Implementation Plan including regulatory, 

environmental and fnancial capabilities. 

Development of the Feasibility Study will 

enable LASAN to pursue federal funding 

opportunities through the Bureau of 

Reclamation’s Large-Scale Recycled 

Water Program.

PLANNING AND ANALYSIS 

Subcriterion 1a – Water recycling mile

needs and opportunities and 

1. Describe the problems and needs in the 

project area. 

The amount of groundwater stored in Los Angeles 

area basins has been in decline for several 

decades. Lack of precipitation due to drought, 

the impacts of climate change, and a rise in 

population and commercial activity within the 

Los Angeles region have resulted in an increased 

demand for surface water and groundwater 

supplies. Declining amounts of surface water 

and groundwater reserves make it necessary to 

identify and utilize new water supply sources to 

sustain the long-term reliability and utility of local 

groundwater basins and decrease the region’s 

dependence on increasingly scarce and expensive 

imported water supplies. 

About one-tenth of the City’s water supplies 

comes from local groundwater with the remaining 

90 percent supplied by non-local sources. The San 

Fernando Valley Groundwater Basin (SFGWB) is 

the largest aquifer within the City, but more than 

two-thirds of its 115 water wells are not in use 

due to groundwater pollution dating as far back 

as the 1940s. 

According to the County of Los Angeles Draft 2045 

Climate Action Plan, extreme weather events in 

the region are expected to increase in intensity 

and frequency. Due to climate change, the area 

is likely to experience drier periods than what 

the region has historically experienced, followed 

by much wetter periods with more extreme 

rain events. This meteorological “seesaw” may 

potentially lead to increased water scarcity, 

mudslides, and fooding. 

These dramatic weather shifts make many of the 

City’s current sources of water unreliable. The City 

procures a majority of its water from Metropolitan 

Water District of Southern California (MWD), which 

receives much of its sources from SWP. SWP, a 

water storage and delivery system, extends 700 

s from the Sacramento-San Joaquin Delta 

supplies 30 percent of Southern California’s 

water supply. SWP allocations have become 

increasingly variable, driven in part by the state’s 

recent multi-year drought. The last time SWP 

provided 100 percent allocation was 2006, with 

recent allocations ranging between 0 (2022) and 

20 percent (2021). The 2023 allocation is currently 

set at 5 percent. 

The Colorado River, via CRA, serves as another 

major source of water for the City through MWD, 

and is at critically low levels due to drought and 

decades of overdrawing. The 40 million users 

of the river’s waters in seven states have been 

asked to cut their consumption voluntarily or face 

mandatory restrictions. With 25 percent of MWD’s 

source water from the CRA, cutbacks could impact 

the City’s water supply reliability. 

Furthermore, infrastructure conveying the City’s 

imported source waters -- SWP, LAA, and CRA -- 

must cross the San Andreas Fault among others, 

making them vulnerable to seismic activity and 

putting the majority of the City’s drinking water at 

risk if a major earthquake were to occur. 

Lastly, the demand for water is expected to 

increase in the region in coming decades. An 

anticipated 0.64 percent annual growth rate in 

the next quarter century will add approximately 

750,000 people to the region, according to the 

Southern California Association of Governments 

(SCAG), increasing water demands on the system 

while also increasing wastewater fow. Paired with 

the other risk factors and needs, it is essential 

6 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

for the City to develop a local 

resilient water supply to reduce 

its reliance on imported water. 

By utilizing the most signifcant 

untapped local water source 

and treating it to high quality 

recycled water, the Hyperion 

Figure 2: Past (2016-2020) and projected (2035) water supply sources for the City. 2035 Program, including Phase 

1 Project, will diversify the City’s 

water supply and thereby increase its resiliency 

and reliability. 

2. Describe the current and projected 

water supplies and demands in the 

project area. 

Primary sources of water for the LADWP service 

area are the SWP, CRA and LAA. These supplies 

are classifed as imported because they are 

sourced from outside LADWP’s service area. 

Approximately 90 percent of the City’s water is 

obtained from non-local sources (see Figure 2). 

Implementation of the Phase 1 Project provides 

a new, local reliable water supply meeting 10 

percent of the City’s demands and moves the 

City towards its local water supply goal of 70 

percent by 2035. 

The City’s current water supply mix results in a 

heavy dependence on snowfall and sufcient 

storage in Northern California, the Eastern Sierra 

Mountains, and the Colorado River watershed. 

In recent years, drought conditions and climate 

change have impacted the amount of snowfall 

in the Eastern Sierra and the Colorado River 

watershed. The Bureau of Reclamation has asked 

the seven states who rely on Colorado River 

water to come up with a plan to reduce their use 

of the river’s fow by 2 million to 4 million acrefeet a year. 

As the availability of non-local water supplies 

fuctuate, so does the City’s ability to import water 

from these sources reliably. Although projections 

of water supply and demand imbalances difer 

based on factors including population, drought, 

rainfall, climate change and other factors, 

analyses performed by MWD indicate there is a 

signifcant risk of shortfall of available water for 

MWD member agencies of up to 66 percent by 

2045. Please see Figure 3 for more information. 

Recent City studies have shown that availability of 

water from LAA is also at risk. LADWP completed a 

climate change study (2011 Climate Study) on the 

Eastern Sierra Nevada region to evaluate potential 

impacts to the LAA system. Results suggested 

an increase in temperature of 8°F, a reduction 

in precipitation of 10 percent and a reduction of 

snowpack in the Eastern Sierra Nevada region by 

the end of the 21st century. A 2020 update to the 

study showed similar results. These hydrologic 

changes may limit the City’s ability to tap LAA as a 

source water. 

While supply of water dwindles, however, demand 

in the region continues to grow. The City’s service 

area population is expected to continue to grow 

over the next 25 years at a rate of 0.64 percent 

annually. This rate is similar to the historical 0.7 

Figure 3: Risk of shortages of water for MWD member agencies 

during periods of high demand and low water availability.

percent annual growth rate from 1980 to 2020 

and will lead to approximately 765,112 new 

residents over the next 25 years. 

3. How planning activities will 

investigate potential uses/markets for 

reclaimed water 

The City has considered three strategies for 

instituting a recycled water program at HWRP: 

 Potable reuse with groundwater augmentation - 

Projects that would spread (infltrate) or directly 

inject recycled water into a groundwater basin 

that could be used as potable water after 

extraction and further treatment. 

 Potable reuse with raw water augmentation 

prior to delivery - Projects that would deliver 

advanced treated recycled water (purifed 

water) to a conventional water treatment plant 

before distributing into a potable water system. 

 Potable reuse with treated water augmentation 

prior to delivery into the potable water 

distribution system - Projects that would 

deliver advanced treated recycled water 

(purifed water) directly to a potable water 

distribution system. 

Based on initial analyses, potential identifed uses 

for IPR water quality associated with the Phase 1 

Project include: 

 West Coast Basin demands such as the 

Water Replenishment District of Southern 

California’s (WRD) West Coast Barrier (WCB) 

injection (15,000 AFY) and Title 22 West Basin 

Municipal Water District (WBMWD) customers 

(20,000 AFY). 

 Future potential demands include LADWP 

injection in the Central Basin (30,000 AFY), 

WCB Injection (15,000 AFY), groundwater 

recharge in the Torrance area (8-12,000 AFY), 

LADWP industrial customers (5-15,000 AFY), 

City of Santa Monica recharge (4-5,000 AFY) 

and others. 

Planning grant funds will allow for the further 

investigation of these concept options to 

determine best use of recycled water in terms 

of public health, cost, regulation compliance, 

environmental impact and other factors. Issues 

in need of examination include development 

of an institutional agreement with regional 

project partners and infrastructure modifcations 

necessary to leverage the existing WBMWD 

distribution system for the purpose of indirect 

potable reuse. 

4. Describe the source water that will be 

considered for the project. 

The City completed a comprehensive analysis of 

its source waters. It has considered surface water, 

ground water, wastewater, dry-weather runof, 

ocean water, industrial water and stormwater 

as potential sources in its eforts to decrease its 

reliance of non-local water and address future 

issues – such as drought – associated with 

climate change. 

LASAN operates the City’s sewer collection and 

treatment system, the source of the proposed 

recycling project. The City’s wastewater service 

area consists of two distinct drainage basin areas: 

the Hyperion Service Area (HSA) and the Terminal 

Island Service Area (TISA). The HSA covers 

approximately 515 square miles and serves the 

majority of the Los Angeles population. In addition, 

the service area includes 29 non-city agencies 

that contract with the City for wastewater service. 

Wastewater fows to HWRP are expected to 

remain stable in the next decades and provide a 

plentiful source of water for the proposed project. 

See Figure 4 on the following page for infuent 

fows to HWRP. 

The City has a successful water conservation 

program and one of the lowest per-capita water 

uses among large cities in the nation. Despite 

population growth of more than 1 million people 

in the past 40 years, the City’s water demand has 

been relatively fat since the 1970s.

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

Figure 4: Past and projected efuent infows to HWRP, 

2008 – 2036. 

After analysis of the potential source waters, 

the City identifed advanced treated wastewater 

as the preferred sustainable, cost efective 

and environmentally advantageous solution to 

providing a new and reliable source of water for 

the growing region and is moving forward with 

eforts to recycle 100 percent of its wastewater 

by 2035. Grant funding for Phase 1 Project will 

assist the City by confrming the best approach to 

recycling at the HWRP in a manner that provides 

water supply resiliency for the City’s residents as 

well as that which benefts the environment. 

Subcriterion 1b – Evaluation of project 

alternatives 

1. Describe the objectives that all 

alternatives will be designed to meet. 

Using multiple City analyses investigating the 

City’s future water, a set of criteria was developed 

to weigh alternatives considered to achieve its 

water recycling goals. Objectives that alternatives 

are designed to meet are grouped into four 

major categories: 

Economic: Successful alternatives will have 

positive fnancial impact on the City and will be 

measured by their operations and maintenance 

costs and likelihood to obtain outside funding. 

Resiliency: Alternatives will be evaluated on their 

resiliency to drought, earthquakes, foods, fre and 

landslides as well as its ability to provide a reliable 

local water supply. 

Implementation: Projects will be assessed 

on their ease of construction; potential for 

collaboration; regulatory approval requirements, 

including meeting evolving water standards for 

IPR and DPR and pumping and storage rights; and 

public engagement and support. 

Environmental: Alternatives will be designed 

to provide an ecological beneft as well as 

environmental justice and service to previously 

underserved communities. 

The City has implemented a collaborative 

approach to explore and evaluate project 

alternatives to develop a resilient community 

that can withstand drought and climate 

change, including: 

 Stormwater – Stormwater projects capture or 

use stormwater to increase water supply and/or 

meet water quality goals. 

 IPR – Treated recycled water is blended with 

other environmental bufers such as a river, 

reservoir or groundwater basin before the 

water is reused. Regulations are in place in 

California to guide the implementation and 

operation of such projects. 

 DPR – Advanced treated recycled water is 

distributed directly into a potable water supply 

distribution system downstream of a water 

treatment plant or into the source water supply 

immediately upstream of the water treatment 

plant. Regulations for DPR in California 

are pending. 

 Other Concepts – Other concepts including 

sewer rerouting projects, non-potable reuse 

(NPR), and water conservation measures. 

2. Describe how the planning activities 

will develop project alternatives. 

LASAN and LADWP have completed a number 

of planning activities over the past fve years 

to identify, evaluate and rank water supply 

9 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

alternatives which have resulted in the 

identifcation of the Phase 1 Project. However, 

LASAN seeks to complete additional studies 

to develop an optimal regional recycled 

water program that meets the City’s recycled 

water goals. 

Alternative evaluations were completed as part of 

the One Water LA 2040 Plan. The plan provides an 

integrated framework for managing of the City’s 

water resources with a focus on sustainability. It 

resulted in the identifcation of over two dozen 

water supply concept options. Through a series of 

technical workshops, stakeholder meetings and 

multi-agency collaboration, three strategies were 

carried forward – all focused on implementing a 

recycled water program at HWRP, as described in 

Criterion 1a.3. 

LASAN completed a feasibility study in 2020 to 

refne the preferred alternative of converting 

HWRP to an advanced water purifcation facility. 

The study confrmed that HWRP has sufcient real 

estate to convert the south side of the plant from 

secondary treatment to full recycling that meets 

anticipated direct potable reuse regulations for 

the plant fow (including wet weather fow). LASAN 

conducted a treatment process evaluation study 

in 2021 to focus on technologies and provide a 

recommendation on the preferred technology for 

the Hyperion 2035 Program. 

LASAN is currently constructing a MBR pilot 

facility at HWRP to test efectiveness of MBR and 

to establish design criteria for the design of the 

Phase 1 Project and subsequent phases. Additional 

studies to develop and progress the Phase 1 

Project and the overall recycled water program 

are being undertaken by LASAN, in collaboration 

with LADWP and WBMWD (not part of the funding 

request). The Technical Studies, Facility Master 

Plan (PIP), and Concept Design Report proposed 

under this grant application enable LASAN 

to identify the optimal and preferred Phase 1 

Project, including treatment and recycled water 

application site(s). Evaluations conducted thus 

far have identifed the conversion of the highpurity oxygen aeration basins to become the 

reactors (on air) as part of the MBR treatment 

process. Proposed planning activities will advance 

the design requirements and facility layouts to 

implement MBR and to add AWPF at the HWRP 

to produce IPR water, and ultimately DPR water. 

LASAN continues to vet alternatives proposed 

by other parties (e.g. continuing conventional 

activated sludge as opposed to utilizing MBR), 

and participates in joint assessments of advanced 

treatment process locations to best leverage 

the regional infrastructure for treatment and 

distribution of recycled water. 

3. Provide a general description of 

the selected project including project 

features, benefits, anticipated costs, and 

analyses conducted. 

The City of Los Angeles, the second largest 

city in the nation by population, imports 90 

percent of its water supply. HWRP is the City’s 

oldest (constructed in 1894) and largest water 

reclamation plant with a peak wet weather 

fow capacity of 850 MGD. It is also the largest 

WRP in the Western United States. Currently, 

HWRP is operated as a full secondary treatment 

facility utilizing a high purity oxygen-activated 

sludge (HPOAS) process with most of its efuent 

discharged to Santa Monica Bay through a 5-mile 

outfall terminating at a depth of 200 feet. Through 

the Hyperion 2035 Program, the City plans to 

provide 45 percent of the City’s water demand 

by recycling 100 percent of HWRP wastewater, 

thereby creating a new, reliable and resilient 

water source for the region. The multibillion 

Hyperion 2035 Program requires phasing not 

only due to its complexity and magnitude but 

also because of HWRP site constraints related 

to keeping the secondary treatment operational 

during the construction of the new facilities.

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

The Phase 1 Project, with a construction cost 

of $1.4 billion (in 2022 dollars), is the frst 

major phase of the project and implements 

critical infrastructure to deliver 56,044 AFY of 

IPR water. The Phase 1 Project consists of fve 

main components: (1) enabling primary efuent 

conveyance modifcation projects; (2) conversion 

of secondary treatment to MBR (more compact 

and producing higher efuent quality) including 

nitrifcation/ denitrifcation; (3) construction 

of AWPF at HWRP that produces 56,044 AFY 

of IPR; (4) modifcations to the WBMWD pump 

station for recycled water pumping; and (5) 

sidestream treatment facility to enhance the 

secondary treatment. 

The specifc elements part of Phase 1 include: 

 Addition of diurnal fow equalization, fne 

screens and new intermediate pump station 

(and associated odor control) to address the 

hydraulic grade line 

 Retroft of existing aeration basins to become 

part of the MBR process 

 Construction of AWPF facilities (RO and UV 

AOP systems) 

 New power infrastructure for an increase in 

power demand due to new processes. 

 Demolition of facilities (e.g. clarifers will be 

demolished to accommodate membrane 

separation tanks and AWPF facilities 

[RO, UV AOP]). 

 Modifcation to the WBMWD efuent pump 

station and cleaning of the pipeline to be 

utilized for the distribution recycled water 

through the existing distribution system. 

Analyses conducted to date include the One 

Water Plan, HWRP Spatial Feasibility Study (2019) 

and Process Alternative Analysis (2021). LASAN 

conducted approximately 10 Hyperion 2035 

Informing Technical Studies (ITS) to assess process 

integration, provisions for DPR, power demand, 

conveyance within the plant, ROC management 

and secondary clarifer improvement potential. 

LASAN has also started early project scoping 

to identify and expedite implementation of 

foundational projects and is initiating work on the 

PIP that will provide the blueprint for Hyperion 

2035 Program elements. 

The Phase 1 Project provides social, economic and 

environmental benefts on a local and regional 

scale in addition to the direct water supply 

beneft of 56,044 AFY. These benefts include 

conformance with current/future regulatory 

standards, water quality improvements, water 

portfolio augmentation and diversifcation, 

operational fexibility to address climate change, 

economic and cost efective solutions reducing 

rate payer burden, water supply reliability, local 

job creation, and workforce development. 

4. Include a preliminary schedule. 

Phase 1 Planning activities, will be completed

EVALUATION CRITERION 2 – 

STRETCHING WATER SUPPLIES 

1. Potential to reduce, postpone, or 

eliminate the development of new or 

expanded non-recycled water supplies. 

The extended drought conditions in the Western 

states and associated SWP, LAA, and CRA 

cutbacks have resulted in variability in the 

availability of the City’s SWP, LAA and CRA water 

sources and severely limit the ability of the City 

to increase its imported water allocations to meet 

future demands. For additional water supplies, 

the LA One Water Plan considered potential water 

supply alternatives, including ocean desalination; 

groundwater basins with and without treatment; 

stormwater capture/treatment; and potable reuse. 

If the Hyperion 2035 Program (IPR and DPR) is not 

implemented, the City will have to signifcantly 

increase the eforts of implementing other 

proposed alternative supplies. 

The augmented supplies from the Phase 1 Project 

will produce 56,044 AFY of IPR quality water for 

immediate application, providing the City with the 

capability of meeting approximately 10 percent 

of current demands, thereby postponing or 

eliminating the development of new or expanded 

non-recycled water supplies both now and in the 

future. The augmentation of the City’s existing 

water supply portfolio with recycled water will 

allow it to decrease, by the same amount, the 

quantity of water the City must obtain from nonrecycled, non-local sources. 

The increase in local reliable water supplies 

provides for a regional solution using 

underutilized resources to provide a sustainable 

water supply source that can be maximized in 

lieu of implementing other approaches such as 

desalination, increasing groundwater pumping 

or other non-recycled water supplies. The Phase 

1 Project is the frst step towards moving the 

City’s water supply portfolio to predominantly 

local water supplies from its imported sources, 

thereby substantially reducing or eliminating 

the need to develop new supplies. 

2. Describe the potential to alleviate 

pressure on existing water supplies 

or facilities. 

The Phase 1 Project will directly alleviate the 

water supply stresses the City has experienced 

in the past by signifcantly reducing the City’s 

dependence on imported water supplies with 

their variable availability and creating a recharge 

supply for local groundwater basins. The City 

secures 90 percent of its water from non-local 

sources, with MWD providing approximately 

49 percent of the supply. MWD obtains its 

supply from SWP suppliers including the 

Sacramento-San Joaquin Delta and the critically 

over-drafted Colorado River, both of which are 

subject to cutbacks. The direct recharge of local 

groundwater basins, through IPR, will enable the 

City to extract approximately 56,044 AFY from 

the basins to use for local potable water supplies 

(meeting 10 percent of the City’s demands), and 

enable the City to reduce its import of CRA and 

LAA waters which will alleviate pressure on the 

imported supply. 

Ofsetting large portions of imported water 

eliminates possible emergency shortages 

as a result of periods of extended drought, 

infrastructure failures or natural disasters. SWP 

distributed to Southern California water purveyors 

is sourced from the Sacramento-San Joaquin 

Delta and delivered via the California Aqueduct 

and Coastal Branch Pipeline. If this conveyance 

system were to undergo major repairs, sufer 

severe damage, or otherwise go ofine for an 

extended period, the SWP-dependent area of the 

City would not be able to receive any imported 

water deliveries. The new water supply provided 

by the Phase 1 Project will enable the City to 

have increased fexibility in deciding when and 

how much SWP, CRA or LAA waters to take in 

a given hydrologic year. This could allow the 

12 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

City to reduce deliveries of imported water by 

56,044 AFY and thus alleviate pressure on the 

Sacramento-San Joaquin Delta and the Colorado 

River basin and/or reduce pressure on local 

groundwater basins. 

3. Describe the potential to make water 

available to address a specific concern. 

The Phase 1 Project addresses concerns 

associated with water supply shortages, water 

supply reliability, groundwater depletion, 

water quality issues and natural disasters (e.g. 

seismic events) that can impact SWP and CRA 

infrastructure and increased costs by producing 

56,044 AFY of a new, reliable water to augment 

local water supplies. 

Water Supply Shortages/Reliability: The 

City’s current supply mix is heavily dependent 

on imported water from Northern California, the 

Eastern Sierra, and the Colorado River Watershed, 

but chronic and more severe droughts reduce 

the reliability of these imported water supplies. 

The year 2022 was the state’s 9th driest in the 

past 128 years. In 2014, drought reduced the 

SWP initial delivery allocation to zero for the 

frst time in history and ended the year at only 

fve percent. CRA deliveries are also vulnerable 

due to two decades of drought and years of 

overdraw, and the river basin’s water supply 

are at historically low levels. The unpredictable 

reductions in imported water supplies have both 

reduced imported water supply reliability and 

increased stresses on many groundwater aquifers. 

As climate change makes weather patterns 

more volatile, the City realizes it must decrease 

its reliance on non-local water supplies and 

develop a reliable and resilient source of water for 

its community. 

Groundwater Resiliency: The Phase 1 Project 

will also address concerns about groundwater 

basin resiliency and sustainability by decreasing 

the region’s reliance of groundwater as a 

source and eliminating the negative efects of 

overdrafting, such as seawater intrusion, which 

may further threaten its use as drinking water. The 

City has sourced approximately eight percent of its 

drinking water from groundwater in the past fve 

years. Several of the City’s groundwater basins are 

adjudicated, and wells have been removed from 

service due to pollutants from industrial waste 

left decades ago. While the City works actively to 

counteract past pollution and ongoing efects of 

climate change, IPR quality recycled water could 

assist by recharging basins and reducing seawater 

intrusion into the region’s drinking water aquifers, 

thereby preserving and improving water supply 

reliability for the area. 

4. Describe the potential to help create 

additional flexibility to address drought. 

Rainfall amounts in the Los Angeles region are 

highly variable, ranging from 4 inches to 37 

inches annually between 1922 to 2016, with 

the total annual accumulation decreasing over 

time. According to the LADWP, hot and dry 

conditions increase water demand in the region 

by approximately 5 percent. The long periods of 

drought experienced by the region since 2012 

have placed pressure on the system to make 

more water available. Population growth is also 

expected to further increase demand. 

Because it imports 90 percent of its water from 

non-local sources that are subject to signifcant 

hydrologic variability, the City is vulnerable to 

drought and other efects of climate change 

experienced in the regions where its water is 

sourced. As discussed in Criteria 1a.2, these 

sources have become less reliable as drought 

conditions become more frequent. 

The Project’s recycled water is resilient to 

droughts because it is not dependent on 

hydrologic conditions and is generated 

directly from a reliable source water, the City’s 

wastewater. Conveying HWRP’s recycled water 

to local groundwater basins provides a resilient 

water supply that increases operational fexibility 

13 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

and redundancy to the City’s water portfolio 

thereby enabling it to better address drought. This 

supply can be used to meet demands or remain 

in the aquifer as storage for emergency use or 

other operational needs. Within the West Coast, 

Central, and San Fernando Valley Groundwater 

basins, there exists approximately one million 

acre-feet of available storage capacity, according 

to the LADWP’s 2020 Urban Water Management 

Plan (UWMP). 

Working in conjunction with WRD, the proposed 

project may utilize this storage potential by 

conveying IPR to the West Coast Seawater Barrier 

(WCSB) to help mitigate seawater intrusion, as well 

as to new injection wells located in the Central 

Basin and the San Fernando Valley Groundwater 

Basin. Each basin may serve an essential role 

in maximizing local groundwater storage. This 

will allow the City to maintain a reliable and 

diversifed water supply in the event of emergency 

scenarios such as drought or disruptions in 

imported supplies. 

EVALUATION CRITERION 3 – 

ENVIRONMENT AND WATER QUALITY 

1. Describe the potential to improve the 

quality of surface water or groundwater. 

Local groundwater is a key resource that the 

City has relied upon as a major component of 

its water supply portfolio. In the past fve years, 

local groundwater provided approximately 

eight percent of the total water supply for Los 

Angeles. Many of the region’s basins, including 

the San Fernando Valley, West Coast and Central 

basins, are adjudicated or due to the presence 

of contaminants require treatment to be used 

- potentially limiting the amount of water that 

can be sourced from the basin. In the San 

Fernando Valley Basin (SFVB) alone, LADWP has 

115 water supply wells, only 41 of which could 

be operated as of December 2020, according 

to the 2020 UWMP. In the neighboring Sylmar 

Basin, contamination has caused two of three 

water supply wells to be removed from service. 

Water supply wells in the Central Basin have been 

impaired, taken out of service, and demolished 

as a result of groundwater contamination 

concerns. Water quality problems associated 

with total dissolved solids (TDS), chloride, 

and hydrocarbon pollutants caused LADWP to 

discontinue utilizing its West Coast Basin facilities 

in 1980. Furthermore, declining groundwater 

levels and potential overdraft conditions 

have become additional concerns for local 

groundwater basins where decades of expanding 

urbanization, increasing impervious hardscape, 

and channelization of stormwater runof have 

diverted natural groundwater recharge away from 

local aquifers. 

These challenges have prompted the City to 

renew its focus on its groundwater basins. With 

careful planning and remediation, the amount of 

water available for extraction could increase or 

decrease based on the management of the basin. 

Of the reuse application alternatives that will be 

studied further under the Phase 1 Project, three 

include recharging recycled water into basins as 

IPR, which may assist with groundwater long-term 

sustainability, resiliency, and reliability. 

1. Treat HWRP efuent with AWPF and recharge 

it into West Coast Basin by injection wells. 

2. Treat HWRP efuent to supply the seawater 

intrusion barrier operated by the Los Angeles 

County Department of Public Works and help 

replenish the West Coast Groundwater Basin. 

3. Treat HWRP efuent with AWPF and recharge 

it into Central Basin by injection wells. 

The use of IPR quality recycled water for 

groundwater recharge will not only reduce 

overdraft in the basin, but it will also improve 

the basin’s water quality by reducing total 

dissolved solids (e.g. salts) and other constituents. 

Planning grant funds would be used to help 

determine which reuse strategy would be best for 

14 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

improving basin health, achieving groundwater 

augmentation and enhancing drought resiliency of 

the City’s water supply. 

2. Potential to improve effluent quality 

beyond levels to meet State or Federal 

discharge requirements. 

The Phase 1 Project will produce water 

with effluent standards beyond levels 

necessary to meet State or Federal 

discharge requirements. Currently, the City’s 

existing HWRP must meet secondary treatment 

standards for discharge through HWRP’s ocean 

outfall to the Pacifc Ocean. Implementation of 

the Phase 1 Project will not only enhance the 

secondary treatment at HWRP by using membrane 

bioreactors, but it will also add a new AWPF 

that provides a proven purifcation process 

consisting of reverse osmosis and advanced 

oxidation and disinfection using ultraviolet light. 

The AWPF product water after the UV disinfection 

is near-distilled quality and, therefore, requires 

stabilization to prevent corrosion of conveyance 

pipelines. The stabilized water will then be 

conveyed for injection into groundwater basins. 

The DPR regulations in California are in the 

draft form and expected to be fnalized in 2023. 

Finalization of regulations will assist planning 

activities for the Hyperion 2035 Program expected 

to produce some DPR efuent water quality. 

Planning grant funds would be used to confrm 

the IPR and future DPR efuent discharges 

requirements, establish the Project’s design 

parameters and develop the Preliminary Design 

Report to move the project towards contractor 

procurement. 

By treating up to 56,044 AFY of wastewater 

efuent through MBR and AWPF, the HWRP will 

also reduce its pollutant discharges to the ocean 

and well beyond what is currently required 

HWRP’s discharge permit. Upgrading the existing 

activated sludge secondary treatment system to 

membrane bioreactors will reduce the discharge 

of biological oxygen demand, total suspended 

solids, and nitrogen compounds in the range of 

80-100 percent (Refer to Figure 6). Pilot tests are 

currently underway to also determine the efcacy 

of enhanced removal of chemicals of emerging 

concern in membrane bioreactors. 

Figure 6: Annual mass load to Santa Monica Bay. 

3. Describe the potential to improve flow 

conditions in a natural stream channel. 

Within the current portfolio of water supply 

sources serving Los Angeles, the largest source 

is imported water, representing 90 percent of the 

City’s consumption. Within the imported supplies, 

the largest portion of water imports comes from 

the Bay Delta via SWP and the Colorado River via 

CRA. The recycled water produced by this project 

will ofset a corresponding water demand that 

otherwise would need to be satisfed by imported 

water. This demand reduction translates to a 

greater quantity of water/fow through the Bay 

Delta and the Colorado River. 

4. Describe the potential to restore habitat 

for non-listed fish/wildlife species. 

Native non-listed fsh species in Santa Monica 

Bay include the arroyo chub, California killfsh, 

longjaw mudsucker, Pacifc lamprey, Pacifc 

staghorn sculpin, rainbow trout, shiner perch, 

speckled dace, three-spine stickleback, and 

15 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

others. Currently less than one-third of the 

wastewater tributary to HWRP is recycled. 

Approximately 225 MGD of secondary treated 

water is routinely discharged via a 5-mile ocean 

outfall. While achieving the NPDES permit’s 

requirements in terms of primary constituents 

(solids, BOD and ammonia), the treated efuent 

currently discharged amounts to a signifcant mass 

loading of pollutants into the Santa Monica Bay, 

stressing its assimilative capacity and potentially 

impacting its ecosystem by contributing to ocean 

acidifcation and hypoxia. Recycling of HWRP 

efuent, in lieu of the current ocean discharge, 

results in a smaller fow volume and signifcantly 

lower mass loadings to the bay (as noted in 

Criterion 3.2) thereby reducing impacts to the 

bay’s ecosystem and restoring its habitat. 

5. Potential to provide water or habitat 

for federally listed threatened or 

endangered species. 

One of the greatest challenges facing the health 

of the San Francisco Bay Delta ecosystem is 

increasing water demand and negative impacts 

associated with corresponding withdrawals. As 

delineated in Criterion 3.3, the Phase 1 Project will 

create a new, substantive and sustainable water 

supply thereby reducing demand exerted on the 

Bay Delta as a potable water supply serving Los 

Angeles. Increased fow in the delta will enhance 

the habitat for sensitive aquatic species such 

as the tidewater goby, white abalone 

and black abalone (federally listed as 

endangered); Delta smelt (federally 

listed threatened); pink and green 

abalone (federally listed as a species 

of concern); giant sea bass (listed as 

a critically endangered species by the 

International Union for Conservation 

of Nature and Natural Resources); and 

longfn smelt (state listed threatened), 

as well as numerous non-listed species. 

EVALUATION CRITERION 4 

– DEPARTMENT OF THE 

INTERIOR PRIORITIES 

Climate Change The impacts of climate change 

are particularly important in the Western United 

States where water supplies are already limited. 

The City actively monitors climate risks to its 

service area locally and to the watersheds of 

its imported water supplies. These watersheds 

spanning across the Western United States, 

include the Eastern Sierra Nevada, Northern 

Sierra Nevada, and the Colorado River Basin 

where water supplies from the LAA, SWP, and CRA 

originate, respectively. 

Given that the City is dependent on imported 

water supplies, it is highly vulnerable to ongoing 

drought conditions. Like much of California, the 

City and region has experienced intermittent 

periods of prolonged drought in the past 

two decades: 

 2012: Moderate drought 

 2014, 2015, 2016: Extreme to 

exceptional drought 

 2018: Severe Drought 

 2021, 2022: Severe drought 

Drought monitor maps (Figure 7) for the last 

three years show that the entire region was 

listed Abnormally Dry to Extreme Drought. These 

dry periods have wide-ranging impacts on the 

Figure 7: National Drought Monitor Map (2020, 2021 and 2022) 

16 
US BUREAU OF RECLAMATION WATERSMART: WATER RECYCLING AND DESALINATION PLANNING

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

region, from escalated wildfre risks, decreased 

groundwater levels, decreased imported 

water supplies and increased water demand. 

Implementation of the Project will move the City 

towards a more climate-resilient place that is able 

to address an increasingly unpredictable climate. 

This means not only preparing for droughts, but 

also for increasing temperatures, more intense 

precipitation events, sea level rise, risk of wildfres 

and damage from high winds. 

The Project addresses climate change by 

increasing the region’s water supply resiliency 

by creating drought resistant water supply and 

infrastructure that is food-safe and seismically 

resilient. The recycled water supply includes IPR 

through storage in the region’s groundwater 

basins for future extraction as a local water 

supply or, in the future, DPR for addition to the 

City’s potable water system. Development of a 

reliable recycled water supply will help the City 

lessen its reliance on non-local sources which are 

threatened by climate change impacts and may 

be further restricted in future years. This new 

supply may be tapped during drought and other 

climate-impacted disasters in the region to ensure 

residents have access to clean water at all times. 

Finally, injection of recycled water into aquifers 

can help prevent saltwater intrusion due to sealevel rise and overdraft. 

Disadvantaged or Underserved Communities 

According to the 2020 U.S. Census, 17.2 percent 

of City residents are below the poverty line, 

approximately 1.4 times above California’s rate of 

12.3 percent. The City contained 170 high-poverty 

neighborhoods in 2018, an increase from 139 in 

1980. Median household income is $70,372, about 

80 percent of the State’s MHI (Census, 2020). 

Figure 8 shows the service area boundaries of 

LASAN along with the disadvantaged communities 

(DACs) (orange shading on map) and severely 

disadvantaged communities (SDACs) (brown 

shading on map), as defned by California 

Department of Water Resources (DWR). The 

current DAC and SDAC thresholds are $51,026 and 

$38,270, respectively. 

Disadvantaged communities are disproportionally 

impacted by socio-economic burdens and 

environmental hazards, including climate change 

and drought. Lack of transportation, alternate 

housing, income and other social protections can 

prevent those in poverty from getting assistance 

during periods of environmental crisis. 

The City recognizes that equitable water 

management means reliable, afordable, and safe 

water supplies for all residents. One of the guiding 

principles of the One Water LA 2040 Plan was to 

“incorporate environmental justice into decisionmaking on where projects are implemented and 

focus on increasing benefts in underserved 

communities,” and this principle is a criterion 

used in evaluating alternatives and developing

strategies in the proposed project. The proposed 

project’s goal of recycling the City’s wastewater at 

the HWRP will provide a stable source of water for 

the region including DACs/SDACs communities and 

ensure that droughts, natural disasters and other 

events do not prevent the City’s most vulnerable 

from accessing the water they need for life. 

Fluctuations and increases in water rates can 

create a burden on economically disadvantaged 

communities. The Phase 1 Project, which provides 

for a long-term, reliable, drought resistant water 

supply, also helps the City stabilize imported water 

price fuctuations (beyond the City’s control) and 

minimize impacts on residents, especially those 

on fxed and low incomes. In recognition of the 

challenges faced by many residents, the City has 

continually considered afordability in the Phase 1 

Project by leveraging existing infrastructure to the 

extent feasible. 

Tribal Benefits The project benefts all residents 

of the City, including the Gabrielino Tongva Nation 

and other tribes, by providing an equitable source 

of water and contributing to the replenishment or 

restoration of groundwater basins. Local tribes will 

be consulted during the CEQA process to ensure 

that tribal interests are fully acknowledged. 

EVALUATION CRITERION 5 – 

WATERSHED PERSPECTIVE 

1. Will project implement a regional or 

state water plan or an integrated resource 

management plan? 

The Hyperion 2035 Phase 1 Project implements a 

number of state and regional water plans. 

The 2020 California Water Resiliency 

Portfolio (Portfolio) represents the Governor’s 

blueprint for state water management. The 

portfolio encourages water supply diversity, 

treatment of compromised supplies, infrastructure 

improvements, and climate impact preparedness 

(including reduced reliance on SWP). The Phase 1 

Project supports the portfolio’s goal of having 

local and regional agencies reuse at least 2.5 

million AFY by 2030. 

The Phase I Project also supports the State’s 

2018 Recycled Water Policy, which recognizes 

the importance of recycled water as a critical 

water supply for California. The policy includes 

a goal of increasing recycled water use to 2.5 

million AFY by 2030 and maximizing recycled 

water in areas where groundwater is in a state 

of overdraft. 

As a member of the Greater Los Angeles County 

(GLAC) Region, the City has participated in the 

development of the 2017 Upper Los Angeles 

River Subregion Integrated Regional Water 

Management Plan (IRWMP), a collaborative 

efort to manage regional water resources. The 

IRWMP plans for the management of water 

resources in the GLAC region for the next 20 

years, including recycled water projects in the City. 

The Phase 1 Project meets the plan’s objectives. 

The City’s Green New Deal expands upon 

the City’s 2015 Sustainable City Plan with the 

goal to secure clean air and water and a stable 

climate, improving community resiliency, and 

other initiatives. The Phase 1 Project will help Los 

Angeles improve its water supply resiliency by 

developing a local, drought resistant, recycled 

water supply; diversifying its water portfolio and 

reducing reliance on imported water. LASAN 

coordinates closely with Operation NEXT (led by 

LADWP) to meet the water management goals of 

the LA’s Green New Deal. 

The City’s 2020 Urban Water Management 

Plan (UWMP) provides water supply planning 

through 2045. It identifed that recycled 

water from the HWRP will help to diversify the 

City’s water supply portfolio by augmenting 

groundwater supplies, replenishing groundwater 

basins and providing other potential reuse 

opportunities.

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

2. Will project help meet the water supply 

needs of a large geographic area, region, 

or watershed? 

The Phase 1 Project provides a clean, safe and 

sustainable source of water supply for the portion 

of Los Angeles County south of the Santa Monica 

Mountains. Depending on the fnal uses of the 

water (see Criterion 1a.3), this water could serve 

customers receiving groundwater from the 

West Coast Basin or the Central Basin, potable 

water service from the LADWP in their City and 

Harbor service areas, potable water service from 

the cities of Torrance and Santa Monica, and/ 

or recycled water service in either West Basin 

Municipal Water District or LADWP’s service 

area. The population in the City that could 

receive water from the project is approximately 

2.5 million. In addition, the population that could 

be served with water from the West Coast or 

Central Basins, Santa Monica, or West Basin 

MWD total approximately 3 million. Therefore, 

this project, could serve a population of up to 5.5 

million people. 

Climate change has resulted in rain and snowfall 

well below historical averages in California 

resulting in extended drought conditions 

throughout the State including the City. These 

impacts have reduced LAA and CRA waters and 

SWP reservoirs to unsustainable levels. The 

SWP, LAA and CRA systems provide water to 

meet City and state demands including drinking, 

environmental, and agricultural uses. Due to the 

drought, SWP allocations have been signifcantly 

reduced. For cities and agricultural users who rely 

on SWP and CRA systems, the reductions have 

resulted in a greater reliance on groundwater 

pumping, which, if over drafted, can cause 

increased seawater intrusion or permanent 

reduction in groundwater storage capacity. The 

Phase 1 Project provides the City with a new, 

sustainable water supply for its service area to 

meet potable water demands and reduce the 

City’s reliance on SWP and CRA. The volume of 

SWP and CRA not utilized by the City could be 

made available for use by local partners or water 

agencies elsewhere. Regional eforts to diversify 

and provide opportunities to better utilize SWP 

and CRA supplies amongst multiple users will 

be an important strategy for adapting to climate 

change in the Western U.S. 

3. Does the project promote collaborative 

partnerships to address waterrelated issues? 

The Phase 1 Project is being developed in 

collaboration with regional partners to ensure 

institutional alignment and optimization of a 

regional solution; enhance collaboration; and 

address water supply shortages in the City and 

the surrounding region. The Phase 1 Project is 

managed by LASAN with LADWP as a key partner: 

LASAN is managing the treatment while LADWP 

will manage recycled water conveyance. LASAN 

and LADWP are conducting partnering sessions 

and regularly meet to discuss technical and 

management aspects of the project. 

In addition, the enhancement of regional water 

supply resiliency is being promoted through 

interagency collaboration with WBMWD, LA 

County Public Works, WRD and MWD. LASAN 

meets at least quarterly with these regional 

partners to help shape the best approach for 

the broader Los Angeles area to build a local 

resilient water supply and reduce dependence on 

imported water. An outcome of these partnering 

eforts includes delivery of IPR water earlier 

than planned by partnering with WBMWD to 

serve existing recycled water demands located 

“south of the Santa Monica Mountains” including 

WRD’s West Coast Barrier injection (15,000 AFY) 

and other West Basin customers (20,000 AFY), 

as well as anticipated future demands on the 

order of magnitude of 80,000 AFY between the 

LADWP injection in the Central Basin, additional 

WCB Injection, recharge in the Torrance area,

PROGRAM FUNDING R23AS00076 // FUNDING GROUP II // FEBRUARY 28, 2023

LADWP industrial customers and City of Santa 

Monica recharge. 

Regional collaboration has enabled the water 

purveyors to prioritize achieving water supply 

resilience, including enhancing efciency and 

cost-efectiveness, while utilizing existing regional 

facilities, contributing to the strong working 

relationship between project partners and the 

greater region. The project has been a catalyst for 

regional collaboration. 

4. Discuss public outreach and 

opportunities for the public to learn about 

the project? 

LASAN and LADWP have been working to 

engage with stakeholders and the public on 

the region’s water supply issues and the Phase 

1 Project. LASAN has conducted outreach 

activities to determine the feasibility of the 

project and share information with stakeholders 

about implementation. Community outreach 

activities, initiated in 2020, have included City 

Council meetings, development of a project 

specifc website to provide the community with 

information on project activities and status 

updates, execution of public information/visioning 

workshops, and plant tours. 

Figure 9: Photo of the Hyperion 2035 Project website. 

In 2021, LASAN convened two Hyperion Advisory 

Groups, to discuss the projects challenges and 

opportunities, including: 

 CAG, comprised of community-based 

organizations representing interests including 

economic development, labor, environmental 

justice, energy consumption, air quality, 

equity and more. 

 TAG, comprised of environmental organizations, 

academia, and regulators to discuss topics 

related to outfall discharge, health of the Santa 

Monica Bay, energy and carbon footprints, 

regulations and permitting. 

LASAN is also conducting tours focused on 

two recycled water pilot projects currently 

implemented at HWRP. LASAN has hosted 

elected and appointed ofcials including Antonio 

Villaraigosa, the State’s Infrastructure Advisor, 

to leverage federal dollars in building California 

infrastructure by Gov. Gavin Newsom. LASAN 

intends to continue and expand its public outreach 

eforts including briefng interested stakeholders, 

conducting tours, and engaging the TAG/CAG 

through Project development.

the land in nine of the Western states is in drought conditions, and nearly 60% of the 

area is experiencing extreme or exceptional drought; and 

WHEREAS, the City of Los Angeles (City) is the most populous city of California and 

the second most populous city in the United States. The City is primarily reliant on 

imported water supplies, which are highly vulnerable to cutbacks from droughts, 

environmental demands, natural disasters and infrastructure failures; and 

WHEREAS, social and economic impacts associated with the City's water supply 

challenges include limited supplies to meet demands, increased cost of living, fire 

hazards, natural disasters, and rising imported water cost; and 

WHEREAS, the United States Department of the Interior, Bureau of Reclamation 

(Reclamation)'s WaterSMART Grant Program provides financial assistance for projects 

that seek to conserve and use water more efficiently and accomplish other benefits that 

contribute to sustainability in the Western United States (West); and 

WHEREAS, water recycling projects develop and supplement urban and irrigation water 

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

water shortages, and diversifying the water supply; and 

WHEREAS, these projects provide Los Angeles with new sources of clean water which 

increases water management flexibility and makes our water supply more reliable; and 

WHEREAS, the Infrastructure Investment and Jobs Act was passed in November 2021 , 

which provided $1 billion ($1,000,000,000) over five years for Western water recycling 

programs through Reclamation; and

Re: Letter of Support for the Los Angeles Sanitation and Environment Department

Application for Hyperion 2035 Program - FY2023 WaterSMART Water Recycling

and Desalination Planning Program (Funding Opportunity Number R23AS00076)

Dear Commissioner Touton:

I write in support of the Hyperion 2035 Phase 1 Project proposal submitted by the Los Angeles

Sanitation and Environment Department’s (LASAN) to the Bureau of Reclamation’s FY2023

WaterSMART: Water Recycling and Desalination Planning Program (Funding Opportunity

Number R23AS00076). The requested $5 million will help fund the Phase 1 Project of the

Hyperion 2035 Program (Hyperion 2035).

Hyperion 2035 will produce purified recycled water using advanced treatment, providing Los

Angeles with a local, reliable, and resilient water supply. The Hyperion Water Reclamation Plant

will be transformed into a water recycling hub to produce 230 million gallons of purified recycled

water. This advances the Los Angeles Sustainability Plan to locally source 70% of water needs

and recycle 100% of wastewater.

The Hyperion 2035 Phase 1 Project is the first of three phases to produce 50 million gallons per

day of indirect potable reuse recycled water for injection into groundwater basins by 2032.

Subsequent phases will expand the indirect potable reuse capacity and also include direct

potable reuse. Hyperion 2035 will have the ability to provide approximately 50%of the City’s

water demand, help address current and future periods of drought, and reduce the City’s

reliance on imported water.

Investments are in place toward sustainability and resiliency for the construction of two pilot

projects at the Hyperion Water Reclamation Plant to test the advanced treatment technologies

that will be used for the full-scale transformation to water recycling. Construction of these pilot

projects began in 2021 and is nearing completion. Thus, your support of this application will

The Honorable Camille Calimlim Touton 

Commissioner 

U.S. Bureau of Reclamation 

1849 C Street, NW 

Washington, D.C. 20240 

Dear Commissioner Touton, 

I write in support of the application submitted by Los Angeles Sanitation and Environment 

(LASAN) to the Bureau of Reclamation for a WaterSMART Water Recycling and Desalination 

Planning grant. LASAN is requesting $5 million in funding to support the Phase 1 Project of the 

Hyperion 2035 Program (Hyperion 2035). Hyperion 2035 is expected to deliver 50 million 

gallons per day of purified recycled water to the city of Los Angeles (City) as early as 2032. 

LASAN’s Hyperion Water Reclamation Plant (HWRP) is the City’s largest wastewater treatment 

facility and the largest source of recycled water for potable and non-potable purposes. The 

HWRP serves a population of four million, covering an area of over 600 square miles and 

discharges approximately 220 million gallons per day of fully treated wastewater into Santa 

Monica Bay. The Hyperion 2035 project will transform the HWPR into a water recycling hub 

and produce 230 million gallons of purified recycled water per day for reuse through advanced 

water purification treatment. Under Hyperion 2035, the City of Los Angeles will have local, 

reliable, and resilient water supply. 

If this proposal is fully funded, LASAN will initiate Phase 1 Project of Hyperion 2035 to 

produce purified water and meet indirect potable reuse standards for various uses, including 

groundwater recharge and injection to prevent sea water intrusion. Hyperion 2035 will have the 

ability to provide approximately 50 percent of the City’s water demand. The development of this 

project will allow Los Angeles to address current and future periods of drought and reduce its 

reliance on imported water. 

I ask that you give this application full and fair consideration consistent with all applicable laws, 

rules, and regulations. Should your staff have any questions, please contact Ariana Heydari and 

Janet Mendez in my district office at (323) 651–1040.
