Cross-connection and Backflow Prevention

BPUB's Cross-connection and Backflow Prevention Program enforces state and local backflow regulations.

Access to safe drinking water is crucial, and backflow is a common plumbing issue that can put public health at risk. In Texas, the TCEQ and Brownsville city mandate protection of all actual or potential cross-connections against backflow.

Annual Testing Requiremetns

BPUB Cross-connection and Backflow Prevention Program requires annual testing of backflow prevention assemblies.

BPUB will send out notification letters regarding the annual testing of external and internal backflow assemblies at commercial and residential sites. To satisfy testing requirements, customers must complete the following:

Hire a licensed tester to conduct the test.

  • A licensed backflow prevention assembly tester must perform an irrigation backflow prevention assembly testing.
  • A licensed fireline tester must test a backflow assembly on a "fireline" service.
  • All testing must be coordinated between the customer and the tester.

The tester will complete a Test & Maintenance Report (T & M) for each backflow assembly on the premise.

If the test reveals that the assembly is not operating satisfactorily, necessary repairs must be made to resolve the issue(s) with the backflow prevention assembly. The assembly then will need to be retested by the tester. All backflow prevention assemblies should be able to satisfy all testing requirements at all times.
