Cross Connection Prevention

To safeguard the public water supply of the City of St. Clair from potential Cross Connections, backflows or back-siphonage, the City of St. Clair requires that certain standards be met and that annual reports be submitted on all existing or required backflow devices within City Limits. This page has been created to provide resources to assist in the understanding of the City’s requirements. A hard copy of the backflow prevention test is required to be submitted annually with the updated business license application.
