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.
