IPP / Tributary Map

The Industrial Pretreatment Program (IPP) is the process of eliminating or reducing pollutants before they reach a wastewater treatment plant. We know that some types of pollutants found in industrial wastewater might damage the collection system, compromise the treatment process and could contaminate the waters of the state.

To protect our system and the environment, the Pretreatment Program requires some industrial dischargers to use treatment techniques and management practices to reduce or eliminate the types of contaminants that could be harmful to sanitary sewers. The Pretreatment Program is an essential part of the Clean Water Act's National Pollutant Discharge Elimination System (NPDES). Water Resource Recovery Facilities are authorized by the United States Environmental Protection Agency (EPA) and the Michigan Department of Environment Great Lakes & Energy (EGLE) to administratively monitor and enforce rules and regulations in the areas tributary to their system.

All non-domestic users within the tributary area of the Clinton River, Commerce or Walled Lake Water Resource Recovery Facilities must complete and submit the User Survey for the facility they are tributary to.
