San Antonio, TX Backflow & Grease Trap FAQs

Direct answers sourced from San Antonio Water System (SAWS) — Cross-Connection Control & Backflow Prevention Program and San Antonio Water System (SAWS) — Resource Protection & Compliance FOG Abatement Program regulations.

What happens if I miss my SAWS annual backflow testing deadline in San Antonio?

If your certified tester does not submit your passing Test and Maintenance Report through SAWS's BSI Online portal (bsionline.com/saws/) by the due date on your notice, SAWS automatically charges a non-compliance fee on your water bill: $79.50 for 1–3 assemblies, $110 for 4–9 assemblies, and $168 for 10 or more assemblies, followed by water service termination for continued non-compliance.

What is SAWS's mandatory Annual Grease Interceptor Photographic Inspection rule?

In addition to pumping your grease interceptor at least every 90 days (or within 2 working days whenever FOG and solids reach 25% of wetted depth), San Antonio City Code Chapter 34 Sec. 34-527(d) requires every Food Service Establishment to hire a SAWS-approved licensed plumber or qualified professional once per calendar year to inspect the fully evacuated interceptor and take photographs of all inlet/outlet fittings, internal baffles, walls, and floors. Any defects must be repaired within 90 days, and all records must be kept on-site for 5 years.

How much does a residential irrigation or commercial backflow test cost in San Antonio?

Independent SAWS-registered TCEQ BPAT testers in San Antonio typically charge $65 to $105 for a residential lawn sprinkler PVB/RPZ test (including electronic BSI Online filing) and $75 to $125 per device for commercial properties.
