25 Aug
Summary
- Two new facilities will treat 43 million gallons of groundwater daily.
- New infrastructure significantly reduces Los Angeles's reliance on imported water.
- This investment aims to supply hundreds of thousands of homes with local drinking water.

The city of Los Angeles is enhancing its local water supply with the completion of the North Hollywood Central and North Hollywood West Groundwater Treatment Facilities. These state-of-the-art plants are designed to treat up to 43 million gallons of contaminated groundwater daily.
This initiative represents one of the city's largest investments in local water infrastructure. Mayor Karen Bass highlighted that the facilities will help meet climate goals by reducing dependence on imported water. A third facility in Tujunga is slated for completion by 2027.
Collectively, these facilities will treat approximately 92 million gallons of water per day. This capacity is sufficient to supply up to 400,000 Los Angeles homes annually, a significant stride towards achieving a 70% local water supply target by 2035.
