What to check for Denver
Use this page when the assembly already failed and the next step is repair, retest, and accepted report submission.
- Due basis: Denver Water sends a testing reminder 30 days before the annual test is due, expects certified testers to report results to the Cross-Connection Control office, and can assess a $250 penalty after repeated ignored notices.
- Notice or device clue: Look for the utility name, service address, assembly serial number, account or notice ID, and due date.
- Who is affected: Commercial, industrial, domestic, irrigation, fire-line, and auxiliary-water-supply customers when Denver Water requires an approved assembly.
- Acceptance rule: Use the listed submission method and keep proof that the report was filed with the utility.
- Report workflow: Denver Water test report email workflow
- Credential gate: Certified backflow prevention assembly tester status, ABPA or ASSE certification for domestic and irrigation backflow assemblies, State of Colorado Fire Suppression System Contractor-Backflow certification for fire assemblies
