Liquid Waste Hauler Program

Regulating disposal of hauled domestic, commercial, and industrial wastes

Metropolitan Council Environmental Services (MCES) collects and treats wastewater in the Twin Cities metro area to protect public health and the environment. We own and operate nine wastewater treatment plants and over 600 miles of sewer pipe that convey wastewater from 111 communities to our treatment plants. The wastewater treated at these plants must meet strict environmental standards to ensure that receiving waters are kept clean.

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 MCES facilities

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