Safe Drinking Water


Drought State of Emergency

With California facing water shortfalls in the driest year in recorded state history, Governor Edmund G. Brown Jr. proclaimed a State of Emergency on January 17, 2014 and directed state officials to take all necessary actions to prepare for these drought conditions. DEHS is compiling a resource list for both water system operators and the public to help save water and respond appropriately. This resource list can be found on our Environmental Health Emergencies page.

Cross Contamination and Backflow Prevention

The County of San Bernardino requires that domestic water systems within this jurisdiction are protected against contamination or pollution as a result of inadequate protection due to the lack of or malfunctioning of backflow prevention assemblies. In addition, State regulated water purveyors are also required to monitor backflow prevention devices to meet the California Code of Regulations, Title 17 requirements.

As of 1992, as a means of protecting the drinking water in San Bernardino County, the Division of Environmental Health Services has required that no person shall inspect, maintain, or test water back flow prevention assemblies without a current, valid Certificate of Competence. The certification required by § 33.06510 shall be valid for a period of three years from the date of qualification unless it has been revoked for cause in accordance with procedures established within this Article. Each person applying to qualify for certification or for renewal of his or her certification shall first pay all applicable fees to the County of San Bernardino Department of Public Health, Division of Environmental Health Services (DEHS) for each activity in the amounts set forth in Chapter 2 of Division 6 of Title 1 of the San Bernardino County Code Schedule of Fees.

Currently, DEHS offers four testing dates per year; typically in March, June, September and December. All new registrants must successfully pass a written exam before sitting for the practical exam. All certificate holders who wish to renew must demonstrate competence at the practical exam. Candidates who are successful will receive a certificate and be maintained on our current testers list. DEHS also offers the option of being placed on our commercial testers list that is published on our website and solicited by water purveyors.

For more information on the backflow program or to find out about upcoming backflow certification test dates, please contact DEHS at 1-800-442-2283.

Drinking Water Systems

The Division of Environmental Health Services (DEHS) Small Drinking Water System Program protects public health and safety by inspecting water systems to ensure pure and safe drinking water is supplied throughout San Bernardino County. In partnership with small drinking water systems owners/operators in our County, DEHS conducts routine inspections to prevent waterborne diseases, identify risks of bacteriological, chemical and/or radiological contamination, and provide technical assistance. DEHS has an agreement with the California Department of Public Health, Drinking Water Program (State Water Board) for administration and enforcement of the Federal and State statutes and regulations for any water systems under 200 service connections. Currently, there are 272 small drinking water systems.
