Backflow and Cross Connections

Backflow Prevention Assemblies

Backflow / Cross Connection Control

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 related to its State Laws.  

To meet these provisions, the Texas Commission on Environmental Quality (TCEQ) on January 1,1996, enacted a State Law which requires the public water suppliers to implement 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 possiblity 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 assemblies are designed to protect the public water system from these types of concerns.

Testing of Backflow Prevention Assemblies

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

Southwest Sandhills WSC has chosen to partner with Veop, 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.
