The Industrial Waste and Pollution Prevention (IWPP) section of the Metropolitan Council is the delegated Pretreatment Program authority for the seven-county Metro area. We regulate industrial wastewater discharges through a permitting system.
Industries discharging wastewater into public sewers must apply for an industrial discharge permit unless IWPP determines that the wastewater has an insignificant impact on public sewers.
Industrial Waste is defined as any solid, liquid, or gaseous waste, excluding domestic waste, resulting from any industrial, manufacturing, commercial, institutional or business activity, or from the development, recovery, or processing of a natural resource.
To determine if your business generates industrial wastewater, you will need to complete and submit this survey of your business’s processes and waste.
