Backflow Information

Backflow Testing Program 
Federal and state laws require all water providers to meet certain standards to obtain, treat, and deliver water to protect public health.  Texas Commission on Environmental Quality (TCEQ) requires all water providers to establish a Cross-Connection Control and Backflow Prevention Program.  Generally, this includes establishing requirements for the installation of backflow assemblies or devices preventing the backpressure or back-siphonage from unwanted connections that may threaten public health.  All backflow devices or assemblies:

  • Must be tested upon installation and at least once annually.  Additional testing may be required depending on the health hazard.
  • Must receive a periodic Customer Service Inspection.  The inspections are intended to identify and validate all device locations, their appropriateness, and determine if additional devices are required.

Wylie Northeast SUD has established a Backflow Testing Program to help assure that backflow prevention devices adequately protect the District’s water system from potential health hazards.  The program requires property owners to maintain backflow prevention devices in good working order and to provide annual test reports as proof of compliance.  Implementation of this program is mandated by the Texas Commission on Environmental Quality (TCEQ).
