Liquid Waste Hauler Program

The Industrial Waste and Pollution Prevention (IWPP) section of the Metropolitan Council is the delegated Pretreatment Program authority for the seven-county service area. We regulate industrial wastewater discharges through a permitting system.

Liquid Waste Hauler Permits are issued to industrial users who transport and discharge liquid waste to Met Council’s Liquid Waste Receiving facilities.  Liquid wastes include septage, commercial, and industrial wastes. 

Purpose of the Liquid Waste Hauler Program

• To regulate septage and other hauled liquid waste discharged to the Metropolitan Disposal System
• To designate and approve adequate facilities for disposal
• To collect equitable load charges for the waste discharged

Permit required to discharge approved liquid wastes at Met Council facilities

Liquid Waste Haulers that want to use Met Council liquid-waste receiving facilities to discharge approved domestic, commercial, and industrial wastes must obtain a permit through the Industrial Waste and Pollution Prevention section.
