Microbrewery Program

Microbrewery and Brewpub Wastewater Discharge Program

Metropolitan Council Environmental Services (MCES) owns and operates nine wastewater treatment plants and over 600 miles of sewer pipe that convey wastewater from communities in the Twin Cities metro area to our treatment plants. The wastewater treated at these plants must meet strict environmental standards to ensure receiving waters are kept clean.

The Industrial Waste and Pollution Prevention (IWPP) section of MCES is the delegated Pretreatment Program authority for the seven-county service area. We regulate industrial wastewater discharges through a permitting system. Microbreweries and brewpubs are included in the nearly 900 industries that are regulated.
