Water Conservation

City Water Conservation
Water conservation is an important topic for all residents and businesses. The two main areas of water conservation that concern the city are protecting our natural resources and passing on monetary savings to the consumer.

The city is actively doing its part to protect the leading water supply for future citizens of North Mankato with the Wellhead Protection Committee. The committee considers ways to protect ground water, researches potential contaminant sources and provides information to the public about protecting our valuable water resources.

Minnesota River, Mankato Watershed

The Minnesota River-Mankato watershed is composed of several small first and second order streams that drain directly into the Minnesota River. Land use in the Minnesota River-Mankato watershed is dominated by row crop agriculture, with corn and soybean production accounting for the about 90% of cropped lands.

County Soil and Water Conservation Districts have identified the primary resource concerns to be sediment and erosion control, stormwater management, drinking water and source water protection, drainage management, waste management, nutrient management, surface water quality and wetland management.
