What is stormwater?
"Stormwater runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters. To protect these resources, communities, construction companies, industries, and others, use stormwater controls, known as best management practices (BMPs). These BMPs filter out pollutants and/or prevent pollution by controlling it at its source." (EPA)
What is illicit discharge?
"Federal regulations define an illicit discharge as '...any discharge to an MS4 that is not composed entirely of stormwater...' with some exceptions." These exceptions include discharges from water-line flushing, landscape irrigation, air conditioning condensate, and discharges from fire-fighting activities. Illicit discharges are considered 'illicit' because "MS4s are not designed to accept, process, or discharge such non-stormwater wastes." (EPA)
As water runs across landscapes and streets into storm drains, it picks up and carries away pollutants such as cigarette butts, trash, salt, vehicle fluids, or yard waste. This contaminated, untreated water eventually makes its way into the Mississippi River where it reduces water quality and clarity and can cause harm to fish and wildlife. Considering our campus' location right along the banks of the Mississippi River, it is essential that we take care of this critical shared resource.
The University of Minnesota's commitment to addressing storm water runoff from campus, as detailed in the campus-specific Storm Water Pollution Prevention Program (SWPPP), is to reduce pollutants to the maximum extent practicable.
How can I help?
Remember – only stormwater down the drain. No dumping of harmful materials such paint waste and auto and household chemicals. In daily life and around campus, you can help by picking up trash and pet waste and avoid use of pollutants like ice melt or salt. If you observe an illicit discharge on campus, please report those findings to the University Health & Safety On-Call Program: [email protected] or 612-626-6004 (24-hr Line)

"Illicit discharges are considered 'illicit' because MS4s are not designed to accept, process, or discharge such non-stormwater wastes." (EPA) As water runs down the street into storm drains, contaminated with illicit discharge (such as cigarette butts, trash, salt, vehicle fluids, or yard waste) from the street, it flows back down through the stormwater system and back into the river. Learn how you can help or report illicit discharge on campus.
Collective action works—and this spring’s Campus Conservation Competition proved it. Over 140 students across 11 residence halls joined the effort to reduce energy use, and the results were clear: small actions added up to real, measurable change. Students led the charge, raising awareness and cutting consumption in just three weeks. The numbers speak for themselves! Read more

The UMN Office of Sustainability and Campus Cleanup Crew are joining for a Stormwater Cleanup event focused on protecting our environment and keeping campus beautiful. Taking place at Knoll Park outside Peik Hall, we invite students to learn about stormwater's impact while taking direct action through litter cleanup. It's the perfect way to give back and get involved! 🌎
Not sure where your waste goes on campus? You’re not alone. The University of Minnesota is working to divert 90% of waste from landfills through recycling and composting. Nearly 60% of trash could be sorted better—your choices matter. Want to help UMN go zero waste? Get involved and join the conversation today. Learn more and take the survey.

In 2024, the University of Minnesota Twin Cities achieved 9,864,660 kilowatt hours in electricity savings, surpassing the highest level of conservation goal set by Xcel Energy. That’s enough electricity to power 1,100 average Minnesota homes for a year and avoid 7.6 million pounds of CO2 emissions. As a result of our efforts through energy projects on campus, the University received $724,815 in rebates, plus an additional $147,246 for reaching our goal. The rebate ultimately goes back into a cycle within the University, allowing us to continue investing in energy reduction and working to reduce our energy use. The pie chart below highlights where these savings came from, with Lighting (35%) and HVAC (24%) contributing the most. Thanks to Energy Management and all who support these efforts!
