Surrounded by all the amenities Los Angeles and Orange Counties have to offer, California Domestic Water Company has been providing water to shareholders since securing water rights in the San Gabriel River Watershed in the 1850s.

The Company’s system begins in Los Angeles County and ends in north Orange County, crossing through El Monte, Industry, Whittier, La Habra, La Habra Heights, and Brea. Along the way, strict quality testing protocols ensure drinking water meets all state and federal safety standards.

The Company is led by an innovative Board of Directors and a modest and resourceful professional staff that plans for today and looks ahead to a future of continued water sustainability.
