The Village of Shorewood's municipal separate storm sewer (MS4) system serves the area of the Village generally west of Oakland Avenue. Approximately 69,000 lineal feet of pipe collect rainwater runoff from both private and public areas such as roofs, parking lots and streets and conveys the water for discharge at various points along the Milwaukee River. A modified storm sewer system also exists within the village's combined sewer system and collects water only from street drains for discharge to Lake Michigan. Please view a system map (PDF).

The discharges from the village's MS4 System are permitted under the Wisconsin Pollutant Discharge Elimination Systems Permit Number WI-S061565-2 (PDF). This permit is issued jointly to the Villages of Bayside, Brown Deer, Fox Point, River Hills, Shorewood, and Whitefish Bay and the City of Glendale.

The Village of Shorewood is required annually to submit a report on its stormwater management activities to the Wisconsin Department of Natural Resources. View the 2019 Annual Report (PDF).

Disconnect Your Down Spouts

In the separate sewer area, the disconnection of downspouts and the installation of rain barrels contribute significantly to water quality improvement. Learn more about using rain barrels and where to purchase them.
