Cross Connection Control Program

The Navajo Nation Environmental Protection Agency- Public Water Systems Supervision Program (PWSSP) requires public water systems to protect their water supplies from contamination by implementing a cross-connection control program and to have backflow assemblies be tested annually. The scope of a comprehensive cross-connection control program must include provisions for the protection of the drinking water supply through the installation of appropriate backflow prevention assemblies at all water user’s connections where a hazard or potential hazard to the water supply is identified by the public water system.

The type of backflow protection required must be commensurate with the degree of hazard that exists on the water user’s premises. Navajo EPA regulations identify the minimum types of backflow protection based on the identified hazard or potential hazard.

Only those persons that have met the requirements of the Navajo Nation Environmental Protection Agency- PWSSP under the Navajo Nation Primary Drinking Water Regulations §2003:

Require to be currently certified as a cross connection control program specialist by the California-Nevada Section of the American Water Works Association or an organization with equivalent certification requirements acceptable to the Director, unless the Director approves an alternative person based on its review of system size, types of water users, treatment, distribution system, and any previous hazard assessment.

Backflow Assembly Tester

All backflow prevention assemblies will need to be tested by a certified backflow assembly tester annually and a copy of the test results mailed to PWSSP. It will be the responsibility of the owner/operator to ensure that testing is conducted annually and the results reported to the PWSSP. PWSSP may inspect these devices and request to view the test results during a sanitary survey inspection.
