A cross-connection is an actual or potential connection between the safe drinking water (potable) supply and a source of contamination or pollution. State plumbing codes require approved backflow prevention methods to be installed at every point of potable water connection and use. Cross-Connections must be properly protected or eliminate

HydroCorp has been contracted by St. Clair Township to assist with their Cross-connection Control (CCC) Program. The CCC program includes two parts: On site inspections and testing of backflow prevention assemblies. The HydroCorp inspector will be conducting a visual inspection of the water uses outside of your facility (outside spigots, lawn irrigation system, secondary sources of water, pools, etc.) to identify cross-connections that could possibly contaminate your drinking water or the public water supply. If your water provider requires an inspector to enter your facilty to evaluate other cross-connection and plumbing hazards inside your residence, you will be notified and instructed to schedule an appointment for your inspection.

St. Clair Township has had a CCC program for over 15 years, which began with inspections of all of the commercial and industrial accounts. As a natural progression of our program we are now inspecting residential customers as required by the State.

All water customers (residential and nonresidential) connected to the public water supply are now required to be inspected for cross-connections. Initial residential inspections will occur from June 2021 through 2026. Residential inspections will occur by region according to this map:

An average inspection normally takes from 10 to 20 minutes, depending on the size of your facility/property.

If you received a letter informing you/the facility of an upcoming cross-connection inspection, please arrange for the appropriate manager/person is aware of the planned inspection.

If you are the owner of the facility being inspected, you are responsible for any needed repairs. Renters may have to refer to their lease agreements in order to determine whether they are responsible for repairs.

All HydroCorp inspectors wear photo ID badges during inspections and are prepared to provide appropriate documentation verifying their identities.
