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.
All microbreweries and brewpubs that operate within the MCES service area (PDF) must register with MCES by submitting a completed Wastewater Discharge Survey for Breweries and Brewpubs.
If your microbrewery produces 500 barrels of beer or more per year, but discharges less than one million gallons of wastewater annually, your brewery falls within our Microbrewery Program. You must submit a completed permit application to us and comply with our microbrewery program.
If your brewery discharges one million gallons or more annually, your brewery must comply with our standard industrial discharge permit program.
How your brewery must comply with the program
- Fulfill all permit requirements and conditions.
- Put in place and follow best management practices (PDF) for microbreweries.
- Enroll in the MCES Industrial Online Reporting System (IORS).
- Submit reports annually via IORS: How to submit your microbrewery annual report.
- Pay annual permit fees and charges as assessed.
