Things You Need to Know About Cross Connections

Holland Charter Township operates a Cross Connection Control program in accordance with the Michigan Safe Drinking Water Act part 14.

A cross connection occurs when a non-potable water comes in contact with the public water supply, which can contaminate the drinking water system through backpressure, backsiphonage or both. Backsiphonage can occur when the pressure in the public distribution system drops. Normally this pressure is high enough to prevent backflow, but certain events such as water main breaks, fire hydrant flushing, or firefighting can lower the system pressure enough to cause a backflow event. Backpressure can occur when the pressure in a private water system is higher than the pressure in the public water system.

By law, it is the customer’s responsibility to install and maintain all backflow prevention devices on their property. It is Holland Charter Township’s responsibility to ensure its customers comply with all state and local cross connection rules or laws.

Examples of Cross Connection:

  • Water driven sump pumps connected to city water

  • Yard sprinkling system

  • Private well connected to city water

  • Water pipes connected a boiler treated with chemicals

  • Faucet connected to a hose

  • Fire protection for a home or building
