Cross Connection and Backflow Prevention Program
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
theinstallation 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
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.
Certified Backflow Assembly Registration

Backflow Testers are required to register and submit application with appropriate documents and fee payable to the Navajo Nation Environmental
Protection Agency-PWSSP. Upon approval by the Director, a Backflow Tester Identification card will be issued. All Registered Testers will be
recognized as certified by an approved cross connection program having met the requirements as established to test within the jurisdiction of the
Navajo Nation.
