Water and wastewater treatment

Water and wastewater treatment

Utilities include Mankato's water treatment, wastewater treatment services and stormwater system.

Mankato strives to offer the highest quality drinking water and meet the community’s expanding water needs in the most environmentally sensitive, cost-effective way for residents.

Mankato’s drinking water meets and exceeds all state and federal standards for high quality water and is in full compliance with the Federal Safe Drinking Water Act. Mankato's wastewater treatment plant is a state leader in meeting wastewater quality standards because the treated wastewater Mankato discharges into the Minnesota River is virtually pollution-free. Mankato's water reclamation facility provides advanced wastewater treatment. Using recycled water instead of taking it from ground water protects our ground water resources. The city of Mankato realized a savings of at least $10 million for this first of its kind agreement.

Mankato's lawn watering conservation program:
Conserving water is the most cost effective way to avoid future problems.  Mankato's lawn watering conservation program deliberately encourages reduction of water usage to ensure stable water delivery and minimize peak demand times.  The lawn watering conservation program applies to everyone watering lawns using city of Mankato water. Since water is a valuable resource, it’s important to conserve water and reduce water usage. Doing so helps efficiently use the area’s groundwater resources and ensures an adequate water supply for residents, businesses and other organizations. Learn more.

Water restrictions are now in place for everyone using city of Mankato water. This decision was made based on lower river levels and strained groundwater supplies, long-term sustainability and the Minnesota Department of Natural Resources (DNR) recently placing Mankato in a moderate drought status. Customers with new sod or new seeding can apply for a 30-day watering permit which will exempt them from the odd/even watering restrictions.
