Cross Connection Control / Backflow


*NOTICE* Changes to the City of Ferris Cross Connection Control Program as of August 11, 2014. 

     The City of Ferris has chosen to partner with Vepo, LLC to allow for the online submission of Backflow Prevention Assembly Test and Maintenance Reports.  All testing information will be entered directly by the tester into the online password protected system provided by Vepo, LLC.  Testers will no longer be able to submit paper test reports directly to the city.

What is a Cross Connection?


     A cross connection is a connection between a potable drinking water supply and a possible source of contamination or pollution. Under the provisions of the Safe Drinking Water Act of 1971, the Environmental Protection Agency (EPA) established national standards for safe drinking water. Each state is required to enforce the various regulations of the Safe Drinking Water Act and how it relates to its state laws.  

     To meet these new provisions, the Texas Commission on Environmental Quality (TCEQ) on January 1, 1996, enacted a new state law which requires the public water suppliers to implement and enforce the Cross Connection Control Program requirements located in the Texas Administrative Code (TAC), Title 30, Chapter 290 of the Rules and Regulations for Public Water Suppliers. 

What is Backflow?

     Backflow is the undesirable reversal of flow in a potable water distribution system. Water that is always under pressure can only flow in one direction. Then how can water flow in reverse? Water will always flow towards the point of lowest pressure. If a water main were to break or if the fire department opened several fire hydrants to help fight a fire, the pressure in the water main could drop. The demand upstream could cause a reversal in flow.  

     Cross connections and the possibility of backflow need to be recognized so they do not occur. A garden hose submerged in a hot tub, swimming pool, car radiator or attached to an insect/fertilizer sprayer could siphon the liquid back into the water main. Water from an irrigation system could be siphoned back into the public water supply. 

     Backflow prevention devices are designed to protect the public water system from these types of concerns.

Do I Need a Backflow Protection Device?

     At any point in a plumbing system where there exists a potential for contamination of the public water supply, a backflow prevention device is required.  


     Click here for a list of common areas where backflow devices are required. 

Am I required to have an inspection at my home?

     If you have a required backflow prevention assembly at your home, you will be required to have it inspected at least annually. 

How do I know if I have a backflow prevention assembly?

     Residential backflow prevention assemblies are most commonly found and required in irrigation systems.  Other locations at residences are possible, but rare. 

    Commercial backflow prevention devices are commonly found in devices that process or utilize water.


     If you are unsure, call 972-842-5761 to schedule a free evaluation.

Does My Device need to be tested?

     All backflow protection devices must be tested upon installation, repair or relocation.  Because backflow prevention devices are mechanical devices that will degrade over time, all backflow devices must be tested annually to ensure they are in working order.

How Do I Become a Registered Tester?

Registration Insructions     

     All Backflow Prevention Assembly Testers (BAPTs) are required to register with Vepo, LLC.  Upon registration and verification of license, insurance, and gauge calibration, the tester will be added to the approved list of Backflow Prevention Assembly Testers.


     Note:  Backflow prevention assemblies on fire protection sprinkler systems are required by the State Fire Marshall to be tested and/or repaired by a BPAT who is a full‐time employee of a fire protection sprinkler company that is licensed with the State Fire Marshall's Office.
