The city term helps discovery. The governing utility still decides the rule, submission method, tester route, and follow-up order.
Dallas annual backflow testing
Annual for high-hazard assemblies; irrigation only on install, repair, or replacement Dallas Water Utilities says high-hazard assemblies require annual testing by a licensed tester registered with the City of Dallas, while lawn irrigation devices are tested when newly installed, repaired, or replaced. Failed devices get a 30-day repair and retest window and submissions run through SwiftComply.
Dallas backflow reporting portal
Use the utility page to confirm whether reports go through BSI, WEIRS, SwiftComply, a city portal, or another official submission path.
Dallas failed backflow test
Use the failed-test page when the assembly has already failed and the next step is repair, retest, and report submission.
Dallas irrigation backflow testing
Use this path when the question is tied to sprinkler systems, reclaimed water, outdoor service, or irrigation assemblies.
Dallas fire-line backflow testing
Use this path when the assembly serves fire protection equipment or a managed commercial site.

Backflow reporting portals
How BSI, SwiftComply, and utility customer portals change the real testing workflow after the field work is done.
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.
