Treatment plant tours

Metropolitan Council Environmental Services (MCES) operates the regional wastewater collection and treatment system that serves 110 communities in the Minneapolis-St. Paul metropolitan area.

Every day, MCES's nine treatment plants treat approximately 250 million gallons of wastewater to protect the public's health and environment.

Several of our treatment plants offer a limited number of tours each month to show the general public how the water they use from nature is cleaned and safely returned to the environment.

Visitors see the various ways pollutants are removed from wastewater--replicating nature’s own processes, but in a much-condensed time frame. They also may see how wastewater solids are processed so that they can be beneficially re-used, and how energy is recovered along the way to power MCES treatment plants.
