ABOUT CLWA

What is CLWA?

Castaic Lake Water Agency (CLWA) is a public water wholesaler that provides about half of the water that Santa Clarita households and businesses use. CLWA operates two treatment plants, two pump stations, two storage facilities, and over 17 miles of transmission pipelines.

Our mission

The mission of CLWA is to provide reliable, quality water at a reasonable cost to the Santa Clarita Valley.

Your Water

The Santa Clarita Valley's available sources of drinking water include rivers, lakes, streams, ponds, reservoirs, springs, and wells. CLWA supplements local groundwater supplies with State Water Project water from northern California. This water is treated and delivered to the Santa Clarita Valley's four local water purveyors: Los Angeles County Water District #36, Newhall County Water District, Santa Clarita Water Division, and Valencia Water Company.

CLWA has an ongoing program of water supply testing and protection. Security measures to protect the Santa Clarita Valley's water supply are in place at all facilities. If you have any questions or concerns about your water supply, please call your water provider directly.
