Water Resource Recovery Facility (WRRF)

The four-year construction project is underway. The original components, built in 1956, will be replaced with new facilities focused on increased capacity and improved efficiency. These important upgrades are needed to help improve the digestion process and solids handling.

The WRRF is a regional asset that serves 65,000 people in Mankato, Eagle Lake, Madison Lake, North Mankato, Skyline, South Bend Township, and the Lake Washington Sanitary Sewer District. The city of Lake Crystal is in the planning stages of connecting to the WRRF. In addition, the cities of Granite Falls and Walnut Grove, the Lower Sioux Indian Community, Granite Falls Energy and Archer Daniels Midland in Marshall benefit through phosphorus trading credits.

Funding Sources:
Nearly half of the cost, $35 million, was awarded to the City by the Minnesota Legislature as a 2023 capital bonding project.
