What to check for Mesa

Mesa explicitly treats dedicated landscape meters and landscape sprinkler systems as backflow-relevant cross-connections.

  • Due basis: 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.
  • Who is affected: Commercial, industrial, irrigation, fire-sprinkler, and dedicated-landscape-meter customers, plus residential sites that city code and plumbing rules identify as cross-connection hazards.
  • Program phone: 480-644-6462
Local signals

Signals that matter before you act
