Storm Water Runoff & The Clean Water Act

Storm water runoff is generated when precipitation and snowmelt flows off buildings, parking lots, driveways, streets, lawns, etc.  This runoff can collect harmful pollutants like sediment, oil, grease, chemicals, and other nutrients as it flows over impervious surfaces such as parking lots and streets. Urban areas are often covered by buildings and pavement, which do not allow runoff to soak into the ground. An underground network of storm sewer pipes is used to collect storm water runoff, and discharge it directly into nearby waterways.

The federal Clean Water Act was enacted to control storm water pollution. To meet requirements of the Clean Water Act, the Wisconsin Department of Natural Resources (DNR) developed the Wisconsin Pollutant Discharge Elimination System (WPDES) Storm Water Discharge Permit to regulate the discharge of storm water runoff from Construction Sites, Industrial Facilities, and Municipal Separate Storm Sewer Systems (MS4s).

Storm water discharges from the City of West Bend's MS4 are covered under WPDES Permit No. WI-S050075-3.

Storm Water Management Program

Per MS4 Permit requirements, the City has developed a Storm Water Management Program, which is a living document that provides details on how the City is meeting permit requirements. The plan establishes activities and programs, along with a schedule for implementation. Topics covered within the Storm Water Management Program include:

  • Public Education & Outreach
  • Public Involvement & Participation
  • Illicit Discharge Detection & Elimination
  • Construction Site Pollutant Control
  • Post-Construction Storm Water Management
  • Pollution Prevention
  • Storm Water Quality Management
  • Storm Sewer System Maps
  • TMDL Requirements & Implementation
