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.
