Backflow Prevention / CSI

Porter Special Utility District has partnered with Vepo, LLC for testing of Backflow Prevention Assemblies and Customer Service Inspections (CSI).

Testers will no longer be able to submit paper test reports directly to the District!

Porter SUD customers can go to to find a Certified Inspector of their choosing; The Inspector will then submit the results to Vepo, LLC.

Backflow Prevention Assemblies must be tested upon installation, repair or relocation. All Backflow Prevention Assemblies are required to be tested on an annual basis.

Customer Service Inspections (CSI) are required on all new construction, or remodeled structures with upgraded/altered plumbing.

For more information see the documents below, or contact the District Office at (281) 354-5922.
