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.

Water restrictions are in effect and apply to everyone using city of Mankato water. Since Mankato’s 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.
