Liquid Waste Hauler Program

Regulating Disposal of Hauled Domestic, Commercial, and Industrial Wastes

MCES is charged with the collection and treatment of wastewater in the Twin Cities metropolitan area in order to preserve and protect the environment. MCES owns and operates nine wastewater treatment plants and over 600 miles of sewer pipe that convey wastewater from 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 (LWH) 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 & Pollution Prevention Section.

Haulers must complete and submit an MCES Liquid Waste Hauler Permit Application along with the first year's permit fee (see Rates & Fees). Domestic septage haulers must first obtain a Subsurface Treatment System (SSTS) license from the Minnesota Pollution Control Agency.
