Pick the Aurora backflow path that matches the problem
The city term helps discovery. The governing utility still decides the rule, submission method, tester route, and follow-up order.
Aurora annual backflow testing
Upon installation and annually thereafter Aurora says operational tests by a certified technician must be conducted upon installation and at least annually thereafter, and results must be submitted online before the annual test due date.
Aurora backflow reporting portal
Use the utility page to confirm whether reports go through BSI, WEIRS, SwiftComply, a city portal, or another official submission path.
Aurora failed backflow test
Use the failed-test page when the assembly has already failed and the next step is repair, retest, and report submission.
Aurora irrigation backflow testing
Use this path when the question is tied to sprinkler systems, reclaimed water, outdoor service, or irrigation assemblies.
Why Aurora maps to Aurora Water Backflow Prevention
City search demand maps directly to Aurora Water's governing program.
- Aurora Water customers and property owners whose service requires a backflow prevention assembly, including hydrant users who need RP protection.
- Aurora places responsibility on the billed customer or owner and expects online submission before the annual due date. The practical risk is staying out of compliance with the city's annual testing requirement.

Source-backed workflow
Aurora is a good Colorado utility because it publishes the annual due-date rule, online result submission, responsibility assignment, and a separate hydrant-meter RP requirement.

Anniversary date vs calendar deadline
Why some utilities track backflow tests by anniversary date, while others push owners into a calendar-season or hard-date deadline.
Residential vs commercial backflow rules
Why the local trigger is rarely just residential versus commercial, and how utilities actually split hazard, irrigation, multifamily, and managed-property cases.
