Backflow & Cross-Connections

Backflow
Backflow is the undesirable reversal of flow of non-potable water or other substance into the public water system or consumer's potable water system.

Cross-Connection

Any connection between a public water system or consumer's potable water system and non-potable water or other substance.  An example is the public water system and a homeowner's landscape irrigation system.

Concerns

Only through cross-connection controls and backflow prevention can we be assured that other sources are not contaminating our water system.
