Auxiliary Water System Backflow Requirements

Customers with auxiliary supplies, on or available to their premises, will be required to install Double Check Valve Assemblies (DCVAs), where no actual interconnection with the District system exits, and Reduced Pressure Backflow Assemblies (RPBAs) where interconnections do exist.

The District appreciates your compliance with this important health issue. If you have any questions, please contact the Cross Connection Specialist by calling 253-867-0947.
