Reuse Things to Consider
Match water quality with end userConsider user agreementsRequires advanced treatment of effluentConduct System Separation TestsBackflow prevention requiredSystem Identification/Signage
Water Resources 101
Cross Connection Testing
Prior to reclaimed water service is initiated:• The reclaimed water system is charged with potable water and red dye is added to allow the movement of the water to be tracked. • After it has been verified that there is no red dye coming out of any potable faucet, the system is connected to reclaimed water.

Backflow Prevention
Arizona regulations require all sites with reclaimed water to install backflow prevention assemblies to protect the potable water system from contamination in the event that there is a cross-connection between the reclaimed and potable water systems.
