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.  For other CDPH water-related topics, click here.

DWP is within CDPH's Division of Drinking Water and Environmental Management (DDWEM).  

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.

DDWEM has created LISTSERVs to let subscribers know when its webpages have been updated. Information about subscribing is available here.
