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. Wait for IRWD's determination or notice that the service requires an assembly.
  2. Install an approved assembly type that matches the site hazard.
  3. Use a recognized certified tester to test and maintain the assembly.
  4. Keep the annual testing record and district form current once the assembly is in service.
