In California, Suburban Water Systems provides high-quality water services to over 300,000 customers in a 42-square-mile service area. This area 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 Systems serves customers through a water distribution system that includes 20 wells, 34 reservoirs, and more than 870 miles of pipeline. Groundwater comes from Suburban Water Systems-owned wells in the Main San Gabriel Basin and Central Basin. 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 Systems is regulated by the California Public Utilities Commission.

As with all Nexus Water Group companies, the health and wellbeing of our customers, employees, and our environment is core to Our Mission as a provider of essential utility services. That begins with our people — proud members of their communities, dedicated to delivering safe, reliable, and cost-effective water utility services.
