Backflow Prevention Device Testing and Certification

Approximately 30% of RRWSC service area customers have backflow prevention devices installed on their property. These devices are required to prevent contamination to our public water supply from sources on customer’s premises. The most common sources are swimming pools and irrigation systems but others are possible. When properly installed and maintained these devices prevent potentially contaminated water on customer’s premises from flowing back into our water distribution system and impacting the quality of their neighbor’s and the entire system’s water supply.

It is a state law and TCEQ regulation [TCEQ Rules 30 TAC Chapter 290.47(f)] that these devices be tested and certified annually by a licensed backflow prevention assembly tester.

Since this is an annual requirement, PGMS will be sending out letters to our members with a backflow prevention device requesting they provide updated documentation that their backflow prevention device have been tested and certified to be in proper working order during the last year.

Thanks to those of you who have already sent updated documentation to PGMS. If you haven’t yet complied, expect to receive further communication from PGMS in the near future. Please help us in this effort to protect the quality of our water.
