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.
