Official authority list

City of Marble Falls Backflow Prevention and Cross Connection official backflow tester list

This page mirrors cached entries from the governing authority's published approved, registered, or certified tester list. Public provider profiles stay clearly separate from the official list.

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 Marble Falls page to determine whether annual high-hazard testing applies.
  2. Use the registered tester route rather than a generic provider search.
  3. Have the BPAT submit the test into Envirotrax.
  4. Do not rely on direct paper submission to the City.
