Backflow Prevention/
Cross-Connection Control
To keep the water supply safe from contaminants that could be introduced into the water system through backflow, back siphonage, or back pressure from a customer’s plumbing system, Arizona Water Company administers the Cross-Connection Control Program in compliance with Arizona Administrative Code on Backflow Prevention (R18-4-215).
The program requires the installation, testing and maintenance of approved backflow prevention assemblies on required plumbing systems. Customers must have a backflow assembly inspected and tested annually. Arizona Water Company will notify customers annually by mail when the inspections and tests are due. Customers are responsible for choosing, hiring, and paying their backflow tester to inspect, test, and repair, (if necessary), their backflow assembly. Arizona Water Company maintains the record of the results that are sent in by testers.
Backflow Prevention Assemblies must be tested by a certified backflow tester and results sent within 30 days of the test to Arizona Water Company:
- Upon Installation
- When Cleaned, Repaired, or Overhauled
- When Relocated
- Annually
- As Required by the Regulatory Authority
