WI Stormwater Week is a grassroots effort of organizations throughout the state that work to raise awareness about the sources of stormwater pollution. This week-long event is an awareness campaign that aims to inform, educate, and engage Wisconsin residents on the topic of stormwater pollution prevention through shared, consistent messaging.

Sustaining Partners
As a grassroots collaboration, we do not have paid staff who create, plan, and promote WI Stormwater Week. We have incredible folks who sustain us through the year!
We are grateful to the partners who help keep this website running, support WI Stormwater Week by hosting the webinars, and dedicate hours of work throughout the year to create a free statewide educational program! Thank you!
Local Events
Are you hosting a cleanup or Adopt-a-Storm Drain event during WI Stormwater Week?
Submit your event details so we can track what is happening around the state and tell others how to get involved!
This year, we have a statewide Call to Action for WI residents to get involved with a local cleanup or adopt a neighborhood storm drain. Additionally, residents can find a cleanup through the Alliance of the Great Lakes or host their own!
Proclamation
The Wisconsin Department of Natural Resources (DNR), stormwater collaboratives, and local municipalities from around the state all support Wisconsin Stormwater Week. Read the group’s proclamation submitted to Gov. Tony Evers’ office and share your local community’s support.
