About Us

You are here: Home / Suburban Water Systems / About Us

Suburban Water Systems, a part of SouthWest Water Company, is an investor-owned water utility providing high-quality water and reliable service in an approximately 42-square-mile service area that covers all or portions of Glendora, Covina, West Covina, La Puente, Hacienda Heights, City of Industry, Whittier, La Mirada, La Habra, Buena Park and unincorporated portions of California’s Los Angeles and Orange counties.

Suburban Water serves a population of about 300,000 through a water distribution system that includes 18 wells, 32 reservoirs and more than 800 miles of pipeline. Our network of facilities pumps and distributes approximately 56,000 acre-feet of water annually (an acre-foot of water is about 326,000 gallons, which meets the annual average indoor/outdoor water needs of 1-2 households).

Groundwater comes from Suburban-owned wells in the Main San Gabriel Basin and Central Basin. The well water is disinfected and treated prior to entering the distribution system. This water is supplemented with water purchased mainly from member agencies of the Metropolitan Water District of Southern California (MWD), Covina Irrigating Company, and California Domestic Water Company (Cal Domestic). Suburban Water is regulated by the California Public Utilities Commission.
