Backflow & Customer Service Inspections


Backflow Testing

The Texas Commission on Environmental Quality (TCEQ), the regulatory agency governing High Point SUD, requires protection from contamination of the public water supply.  To ensure this protection, High Point SUD requires an approved backflow assembly on all irrigation systems (sprinkler systems) to provide this protection.  These devices must be tested upon installation and annually by a TCEQ Licensed Backflow Inspector.  The inspector needs to submit the test form to High Point SUD.  You may choose a certified Backflow Prevention Assembly Tester of your choice.  

For all properties with an OSSF (On-Site Sewer Facility, Septic System), you MUST use an RPZ (Reduced Pressure Zone) backflow device. If your property currently has a Double Check backflow device, it will no longer pass inspection; it MUST be replaced with an RPZ.

Customer Service Inspection

Before continuous water service is established for new construction, Texas law requires an inspection of the private water distribution system to help ensure that the water is safe to drink. This type of “customer service inspection” is required in Title 30 of the Texas Administrative Code (TAC), Subsection 290.46(j).  All the rules in 30 TAC 290, Subchapter D, are administered by the Texas Commission on Environmental Quality (TCEQ). These rules are contained in the TCEQ publication Rules and Regulations for Public Water Systems, RG-195.

The purpose of a customer service inspection is to identify potential sources of contamination or illegal lead plumbing materials.
