The City of East Lansing’s Cross Connection Control Program went into effect in 2006, when the Michigan Department of Environment, Great Lakes and Energy (formerly known as the Michigan Department of Environmental Quality) required municipal water suppliers to prevent the introduction of contaminants and pollutants into water distribution systems. The use of backflow prevention devices helps protect this valuable resource.
Examples of Cross Connection:
a direct connection of a garden hose to a chemical fertilizer sprayer
a water supply pipe connection to a dental cuspidor
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.
