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 backpressure from a customer's plumbing system, Scottsdale administers the Cross-connection Control Program.

The program requires the installation, testing and maintenance of approved backflow prevention assemblies on all plumbing systems per the city's plumbing codes and City Ordinances. Commercial water customers must have their Backflow Assemblies inspected annually and will be notified by mail when their inspections are due.

Contractors doing any work on a Backflow Prevention Assembly – including, but not limited to, testing, installation, retrofits and replacements – must be certified backflow testers (PDF).
