Cross Connection Control Program

A cross connection is an arrangement of piping through which water of a questionable quality or other contaminants may enter the public water supply due to backflow.

The City of Sterling Heights is committed to providing customers with safe drinking water. As part of the City’s commitment, a program to help protect the public water supply from contamination due to cross connections is in place.
