Backflow Inspection Testing Requirements 

SAWS Backflow Testing

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.
