Welcome to the State of California 

Public Drinking Water Systems

The Drinking Water Program (DWP) regulates public water systems; oversees water recycling projects; permits water treatment devices; certifies drinking water treatment and distribution operators; supports and promotes water system security; provides support for small water systems and for improving technical, managerial, and financial (TMF) capacity; provides funding opportunities for water system improvements.  For more about DWP activities, click on a link below. 

Private domestic wells are not regulated by DWP; the State Water Resources Control Board has information pertinent to private domestic well water quality.  The Department of Public Health also has some water-related programs; for those, click here

Reorganization Proposal:  The Administration has proposed a July 1, 2014 transfer of  DWP to the State Water Resources Control Board. Find out more at http://www.swrcb.ca.gov/drinkingwater/index.shtml.
