Drinking Water Program


Program Overview

The drinking water program is established to prevent waterborne disease in water wells through permitting and inspecting small public water systems to insure that only potable water is provided to water system users.

*This program does not regulate bottled water or vended water. These are regulated by the CDPH's Food and Drug Branch.
