Backflow Prevention Program

The District's cross-connection program helps in securing the public water supply from potential sources of contamination and optimizing water quality through identifying and eliminating potential cross-connections.

Backflow prevention is the most significant aspect of the cross-connection program, directed at preventing any introduction of harmful substances to the distribution system. Typically, a backflow prevention assembly device is installed at the water meter to protect the public water supply.

SMWD requires all backflow assemblies to be tested annually.  This is the responsibility of the water account holder. The backflow test report form can be found below as well as resources and information on backflow assemblies.
