Cross Connection Control Program

The City of East Lansing's Cross Connection Control Program went into effect in 2006. The Michigan Department of Environmental Quality (DEQ) mandated water protection programs which require municipal water suppliers to provide consumers with safe drinking water to prevent the introduction of contaminants and pollutants into the water distribution system. The use of backflow prevention devices help protect our valuable resource.

Examples of cross connections are:
  • A direct connection of a garden hose to a chemical fertilizer sprayer, or, the water supply pipe connection to a dental cuspidor, as well as lawn irrigation systems.
  • These examples are direct cross connections between potable and non-potable water sources, whereby, the clean water supply may become contaminated and/or polluted due to backflow, unless the proper backflow prevention device is installed.
  • The Michigan Plumbing Code requires all backflow prevention assemblies and air gaps be inspected annually. Testable devices shall be tested at the time of installation, immediately after repairs or relocation, and at least annually. Backflow Test Reports must be submitted for all testable devices within the City's water supply system. The program administrator requests using this fill-in / printable form.
