Annual or event-based timing
Commercial, industrial, irrigation, fire-sprinkler, and dedicated-landscape-meter customers, plus residential sites that city code and plumbing rules identify as cross-connection hazards.
- Upon installation and annually thereafter
- Mesa sends annual notices to regulated customers, requires recognized testers to submit results through the backflow portal within seven days of service, and requires immediate retesting after repair or maintenance.
Non-compliance penalties
Mesa can keep a regulated customer out of compliance if the test is late, the portal filing misses the seven-day window, or the assembly is repaired without an immediate retest by a recognized tester.
- Mesa uses a seven-day result-submission window.
- Repairs trigger an immediate retest expectation.
- Residential irrigation and fire-service contexts both appear in the official program.
Compliance workflow
Official workflow
Every focused page on this utility still runs through this authority sequence. Confirm the rule here before you branch into repair, testing, or provider routing.
- Identify whether the property or device is already in Mesa's regulated-customer pool.
- Use a recognized tester from the city resources.
- Upload the test through the portal within seven days of service.
- If the assembly was repaired, retest immediately and keep the replacement data aligned with Mesa's record.

Residential notes
- Mesa is stronger than many cities on residential coverage because dedicated landscape meters and other residential cross-connections are called out directly.
- Single-family homes are not automatically outside the program if a hazard exists under the plumbing code or city ordinance.
Commercial and managed properties
- Mesa's seven-day reporting requirement and immediate retest rule make the workflow operationally strict.
- Fire and non-fire work are not identical because Mesa separates general testers from fire-contractor resources.
