Industrial Pretreatment Program

The goal of the Industrial Pretreatment Program (IPP) is to protect, preserve and improve the surface water quality of Michigan through the implementation of Federal and State rules designed to limit pollution from industrial discharges to publicly owned wastewater treatment facilities.

Pollutants in industrial wastewater may compromise municipal treatment plant processes or contaminate waters of the state.  To protect municipal treatment plants and the environment, the Pretreatment Program requires industrial dischargers to use treatment techniques and management practices to reduce or eliminate the discharge of harmful pollutants to sanitary sewers.  The Pretreatment Program is a core part of the Clean Water Act's National Pollutant Discharge Elimination System (NPDES).
