Our Sustainable Water Future

We are continuing to expand L.A.’s water supply through facility improvements that will help combat future droughts and climate change while fostering our customers' water-saving efforts through incentives.

To combat periodic droughts and address dramatic swings in climate, we are expanding L.A.’s local and resilient water supply through a major initiative called Pure Water Los Angeles, as well as constructing new facilities to clean up the groundwater basin, improving the capture of stormwater runoff, and increasing the capacity and use of recycled water. We continue to step up incentives to foster our customers' water-saving efforts.

Our Water Supply Achievements

Over 30%

Less water use per person per year in last 15 years

45+ Years

Of mandatory water conservation ordinances

51 Billion Gallons

Stormwater captured in FY 2022-23, equivalent to providing drinking water for 626,400 L.A. households for a year

$130 Million

Amount invested in expanding stormwater capture infrastructure

Pure Water Los Angeles

Pure Water Los Angeles is a water supply and resiliency program being collaboratively developed by LADWP and LASAN to design, build, and operate an exceptionally advanced water purification system. It aims to produce up to 230 million gallons of purified recycled water per day. About 50 percent of Los Angeles’ water comes from our own sources—including groundwater, recycled water, and water delivered by the Los Angeles Aqueduct—with the remaining water purchased and imported from other agencies.

Water Supply Goals

In 2019, Mayor Eric Garcetti issued an update to the LA Sustainable PLAn (L.A.'s Green New Deal) with LADWP and includes targets to increase local water supplies through recycled water, stormwater capture, and water use efficiency.

We’re investing $8 billion in capital improvements over the next several years. Read more about our efforts in the Water Infrastructure Plan (WIP).
