Water Supply

Where Does My Tap Water Come From

Your tap water comes from 2 sources: groundwater and surface water. We pump groundwater from local, deep wells. We also use Metropolitan Water District of Southern California’s (MWD) surface water from both the Colorado River and the State Water Project in northern California. These water sources supply our service area shown on the adjacent map. The quality of our groundwater and MWD’s surface water supplies is presented in this report.


Orchard Dale Water District, in conjunction with La Habra Heights County Water District , operates four production wells at the Judson Well Field in unincorporated Los Angeles County.  The well water is utilized for the Orchard Dale Water District service area year round.
