Backflow & Customer Service Inspections

Customer Service Inspection

Before establishing continuous water service 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 of 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.

A Customer Service Inspection aims to identify potential sources of contamination or illegal lead plumbing materials.  The inspection takes approximately 30 minutes.  Please schedule your appointment by calling the office or emailing or  Operators will need access inside the home, and High Point requires an adult present to complete the inspection.


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; the double-check MUST replace it with an RPZ.

On behalf of High Point SUD, SC Tracking Solutions will send letters and notifications of annual tests. To find a registered inspector, visit  Enter High Point SUD in the City location.  If you'd like to use an inspector not on the list, that inspector must first register with SC Tracking Solutions.  If you should have any questions, don't hesitate to get in touch with
