Wastewater & Water

Metropolitan Council Environmental Services

Clean water and a clean environment are essential to a healthy life, and the Metropolitan Council's Environmental Services division is committed to both.

We treat wastewater for 111 cities and townships with 2.7 million people in the Twin Cities metro area, monitor air and water quality, and plan for a long-range water supply to meet future demand.

We consistently achieve near-perfect compliance with federal and state water discharge standards while holding customer rates to 35% below the national average. We have significantly cut our purchased energy costs in the wastewater system and continue to reduce our climate impacts. 

The Met Council's Environment Committee addresses issues of sewer policy and planning, environmental reviews, wastewater facilities and treatment, water supply, nonpoint-source pollution, and federal and state regulations.

Wastewater collection and treatment

Whenever someone in the Twin Cities takes a shower, flushes a toilet, or runs a washing machine, the used water is routed to one of our wastewater treatment plants through an extensive network of local and regional sanitary sewer pipes. We own, operate, and maintain the Twin Cities metro regional wastewater collection and treatment system, which includes:

  • 635 miles of regional sanitary sewers
  • 230 metering stations
  • 60 lift stations
  • 9 wastewater treatment facilities

The system collects and treats an average of 250 million gallons per day; almost 70% of this is processed at the Metropolitan Wastewater Treatment Plant (Metro Plant) in Saint Paul. The total amount of wastewater treated in 2021 was 82.3 billion gallons. Learn more about wastewater treatment.

Water resources planning and protection

By 2040, the Twin Cities region is projected to grow by 500,000 people. Protecting, conserving, and utilizing the region’s groundwater and surface water in ways that protect public health, support economic growth and development, maintain habitat and ecosystem health, and provide for recreational opportunities is essential to our region’s quality of life and the driver behind the work we do in water resources planning and management and water supply planning.
