Annual Testing of Backflow Prevention Assemblies
Annual testing of backflow prevention assemblies is required by Chapter 24 of the City of San Antonio's Plumbing and Fuel Gas Code, Chapter 34 of the City of San Antonio Code of Ordinances, and the SAWS Cross-Connection and Backflow Prevention Control Program.
SAWS will send out notification letters regarding the annual testing of external and internal backflow assemblies located at commercial and residential sites with alternative water use or on-site sewage facilities (OSSF). Residential reminders for annual backflow assembly testing for lawn irrigation systems are sent quarterly with bill notices.
Test and Maintenance forms should be submitted here.
Please note, only registered testers can submit Test and Maintenance Reports for SAWS customers.
A list of registered testers is available here.
TCEQ Licensed Customer Service Inspectors available here.
