Backflow Prevention
A list of persons certified under the Georgia Statewide Backflow Prevention Assembly Certification Program (GBPAT) is maintained by the Georgia Association of Water Professionals (GAWP), the State’s authorized testing party, at http://www.gawp.org/page/Backflow. The page allows you to “Search Testers”. If you do a general search, it will provide a listing of the current testers. Note that not every tester certified offers the service commercially.

Why does the City of Dallas have this program?
The Georgia Environmental Protection Division (EPD) requires the City of Dallas to have a backflow program. This program is designed to protect the public water supply from pollutants and contaminants that could, under certain circumstances, be drawn into the city water system from private properties.
WHAT IS BLACKFLOW?
Backflow is the reversal of flow in a water system from the normal or intended direction of flow.
WHY IS BACKFLOW PREVENTION
NECESSARY?
To prevent any potential contaminants or pollutants from entering the water distribution system from private plumbing systems; either from back pressure or back siphonage.
WHO IS AFFECTED?
All commercial and industrial customers that have water service accounts from The City of Dallas. Commercial and multi-family customers are required to install backflow prevention assemblies on all potable service connections.
