Backflow and Cross Connection Program

For more specific backflow info see Backflow and Cross Connection Control Program Download or print: Backflow Testsheet

The Fort Worth Water Department is changing its procedures associated with the initial testing of backflow assemblies. Starting September 10, 2012, the department will no longer perform the initial tests of backflow assemblies. These must now be performed by a city registered and certified Backflow Prevention Assembly Tester (BPAT).

The change applies to newly installed, replaced, relocated, or removed backflow assemblies associated with the following:

  • Commercial Facilities
  • Residential Facilities When Applicable
  • Irrigation (Commercial and Residential)

Note: backflow assemblies must be tested by a registered tester prior to requesting an inspection. Incomplete, inaccurate and /or illegible test forms will be considered invalid and will result in a failed inspection.

All registered testers are independent contractors and are not associated with the City of Fort Worth. Contact the Cross Connection Control Section (817-392-8375) for a complete list of registered testers or click here.

General Information

Water distribution systems are designed for one-way water flow, from the distribution system to the consumer. However, hydraulic conditions within the system may deviate from the “normal” conditions, causing water to flow in the opposite direction in unprotected systems. This is called backflow.

Backflow occurs when the pressure in the distribution system drops, siphoning water from the consumer’s system into the distribution system. This is called back-siphonage. Some water customer’s have non-potable materials on the premises under pressure. When an unprotected water line is attached to the container or pipes holding pressurized material the material may be “pumped” back into the potable water system. This is called back-pressure. Either of these conditions will cause any substance that may be in contact with the water system to be directed back into the potable water supply.

Customers have the right to expect the water provided to them by their water supplier to be pure and healthful. The Fort Worth Water Department spends millions of dollars to purify and treat water before it is delivered to the consumer. However, many consumers are not aware that the water supplier also expends great effort to protect the water from the possibilities of contamination or pollution while it flows through the distribution system.

For over one hundred years, there are documented incidents of contaminants and pollutants that flowed backwards into potable drinking water supplies. A few water utilities instituted modest programs, as early as the 1930’s, to prevent backflow from occurring.

Federal and state regulations require water suppliers to protect their water systems from contamination or pollution. To do this the Fort Worth Water Department conducts surveys of high-risk facilities throughout the system. Through these surveys, the Backflow Section of the Water Department determines the extent of backflow protection that is required to protect the water supply and the public from possible contaminants.

The water department also requires annual testing of backflow protection assemblies on all commercial property. Print a blank test sheet and have a registered tester complete the sheet and mail the original to the Backflow Section at the address shown below. Additionally, to safeguard the health and well-being of residents the City of Fort Worth requires that all alternative water sources and contracted meters have a backflow protection assembly. Meters must be protected by a backflow assembly or air gap and the assembly must be tested upon installation, repair or relocation.
