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 a certified backflow testers.

Water Main Disinfecting / Sampling
To keep the water supply safe from contaminants new water mains are required to be disinfected and tested before connecting to the City of Scottdale Water System.
Proper chlorination, flushing, and bacteria sampling are essential to protect the public water supply from contamination. All public water mains must be disinfected and tested in accordance with MAG Section 611 and AWWA Standard C651, while private water mains downstream of backflow prevention devices must also follow MAG requirements under contractor oversight.
Water mains must be flushed and pressure tested prior to disinfection, and no main may be connected to the existing system until it has successfully passed all required bacteriological testing.
