Backflow

What Is Backflow?
Backflow is the undesirable reversal of the flow of water or mixtures of water and other undesirable substances from any non potable water source into the distribution pipes of the potable or drinking water system. Backflow occurs as a result of a “cross-connection” within the water system.  A cross connection exists when there is an actual or potential connection between a potable water system and any non potable source or system.  When a cross connection exists and backflow occurs, the water system can become contaminated and potentially very harmful.

For this reason the City of Cedar Hill requires that all backflow devices be registered with the Public Works Department and that the devices be installed and tested annually by registered, State licensed backflow testers.

Procedures for Backflow Tester Registration & Report Filing
The City of Cedar Hill has partnered with BSI Online to manage and track our backflow prevention program.

Testers will still need to register with the City of Cedar Hill in order to test backflow devices within the City.
Please come to the Public Works / Development Services desk at 285 Uptown Blvd. (2nd floor) to register or to renew your registration. The cost of registration is still $20 annually.

All test reports for existing backflow devices will need to go through BSI Online.
The cost per test report is still $25. For more information, please call 800-414-4990.

Any new backflow prevention devices (not replacements) being installed / tested will need to have their location verified by the City of Cedar Hill and tested by a backflow device tester licensed by the State of Texas and registered with the City of Cedar Hill. The tester who performed the test will register the new backflow prevention devices via the BSI Online services.

A current list of registered testers can be obtained by contacting the
Public Works Department via email or by calling 972-291-5126 ext. 2853.
