What to check for San Antonio

SAWS irrigation compliance is broader than a single annual test reminder. Irrigation systems need the right assembly, and large landscapes can also fall into the separate annual irrigation checkup program.

  • Due basis: Annual testing is required by City of San Antonio ordinance and state regulations. SAWS uses BSI to manage notices, customer service inspections, and customer tracking.
  • Who is affected: Properties with connections that can contaminate the public water system and customers requiring external or internal backflow assemblies.
  • Program phone: 210-233-2910
Local signals

Signals that matter before you act

  • SAWS requires backflow protection on irrigation systems based on the hazard presented.
  • Single-family irrigation tied to septic systems, private wells, or other alternate sources often sits in the annual notice stream.
  • Large landscapes over five acres or very high annual water use may also need an annual irrigation checkup by May 1.
Workflow

San Antonio workflow order

  1. Confirm the property's irrigation hazard class with SAWS or BSI.
  2. Complete the annual backflow test with a licensed BPAT when the assembly is in the SAWS program.
  3. If the site meets the large-landscape thresholds, complete the separate annual irrigation checkup on time as well.
