The City conducts numerous activities that can pose a threat to water quality if practices and procedures are not in place to prevent pollutants from entering the MS4. These activities include winter road maintenance, minor road repairs and other infrastructure work, automobile fleet maintenance, landscaping and park maintenance, and building maintenance. The City also conducts activities to remove pollutants from the MS4 when performed properly, such as street sweeping and storm drain system cleaning.

As a permitted MS4, the City of Manitowoc has developed a Pollution Prevention Report and two site specific Storm Water Pollution Prevent Plans to guide the City in our pollution prevention efforts.
