Hyperion Water Reuse and

Resiliency Program

Program Benefits:

Recycle 100% of Hyperion

wastewater by 2035.

Increase local water supplies to

offset imported water.

Build a resilient storage

supply in local groundwater

basins.

Mitigate potential impacts of

climate change and drought.

Program Objective To address the need for a resilient

and independent water supply for

Los Angeles, LADWP is pursuing a

major initiative aimed at maximiz-

ing production of purified recycled

water from the Hyperion Water

Reclamation Plant to replenish the

city’s groundwater basins. The

Hyperion Water Reuse and

Resiliency Program will help meet

Program Description

The Hyperion Water Reuse and

Resiliency Program is a partner-

ship among LADWP, Los Angeles

Bureau of Sanitation (LASAN), the

Water Replenishment District of

Southern California (WRD) and

Metropolitan Water District of

Southern California (MWD). Cur-

rently in the planning stages, the

program has five key components:

LASAN will retrofit Hyperion

with advanced treatment facili-

ties producing up to 170 million

gallons per day (MGD) of puri-

fied recycled water.

LADWP will collaborate with

WRD on determining the most

optimal locations to convey this

purified recycled water into the

underlying aquifers within the

West Coast and Central

Groundwater Basins to utilize

up to 450,000 acre-feet of

available storage.

LADWP will pump the ground-

water for distribution into pota-

ble system.

LADWP will construct a new

pipeline to the San Fernando

Valley to replenish the San

Fernando Groundwater Basin.

LADWP will potentially convey

water to the Los Angeles Aq-

ueduct Filtration Plant (LAAFP)

and MWD’s Regional Recycled

Water Program’s Backbone

System.

Mayor Garcetti’s 2019 Green New

Deal goal to recycle 100% of

available treated wastewater for

beneficial reuse from Hyperion by

2035.

This new independent water sup-

ply will reduce L.A.’s reliance on

imported water that must travel

hundreds of miles and is vulnera-

ble to drought, earthquakes,

climate change and other natural

disasters. By replenishing ground-

water aquifers in Los Angeles, the

program will potentially meet up to

a third of the city’s water demand.

Next Steps

Initiate a programmatic EIR, mid-2020.

Work with partners to develop a robust stake-holder and community outreach plan.

Evaluate potential funding mechanisms including external funding sources.

Explore opportunities for a Joint Powers Authori-ty with other program participants as a mecha-nism to more effectively manage and fund the program.

Undertake a pilot injection well project to validate preliminary groundwater modeling efforts in the Central and West Coast Groundwater Basins.
