Official authority list

San Antonio Water System Backflow Prevention approved testers

This page mirrors cached entries from the governing authority's published tester list. Sponsor-only inventory stays off public pages and inside the private admin workflow.

Official list entries

Authority-first tester table

Use the governing authority list first. Provider profiles and sponsor routing remain secondary to the official approval context.

No local official entries are cached yet

This route is live because the official program path is strong enough, but the file registry does not yet cache individual tester entries for this utility.

Utility workflow

Stay on the official compliance path

The utility page remains canonical. This tester surface should only help the user take the next step after the exact reporting and deadline path is clear.

  1. Use the SAWS program page to confirm whether the assembly is part of the annual testing program.
  2. Check compliance or find a registered testing company through the BSI customer portal.
  3. Complete testing and make sure the tester submits results through the correct BSI channel.
  4. For new service or construction, complete the CSI and Development Services steps alongside assembly requirements.
