City of Mesa Water Resources: backflow test rules

  • Who must test. Commercial and industrial customers and homes with dedicated landscape meters must install, test and maintain backflow prevention assemblies under Mesa ordinance and state rule R18-4-215. Source.
  • Notices and deadlines. Mesa Water Resources sends notices to regulated customers when an annual test is due; the customer then hires a recognized Backflow Assembly Tester. Source.
  • How the report is filed. Recognized testers (General Tester and Fire Contractor lists) must submit test reports to Mesa's backflow portal (SAMS on crossconnection.njbsoft.com, linked as mesaaz.gov/backflowportal) within seven days of service. Mailed, emailed and faxed reports are no longer accepted. Source.
  • Tester registration. Recognition requires a Tester Application, a signed City of Mesa Backflow Assembly Tester Agreement, proof of tester certification, and a current gauge accuracy or calibration report (Mesa City Code 8-1-12). Source.
  • Fees. Failure to submit testing records on time results in a Backflow Compliance Late Fee (amount in the Utility Service Fees schedule) and possible civil sanction. Source.
