Registration sign-up deadline is end-of-day Sunday, April 5, 2026! Downtown Naperville, Sweep 2021 How It Works Participants register and are assigned to a Community Liaison, who coordinates volunteers to remove litter from a nearby section of river. Streambank restoration activities, such as removing invasive species and planting native species, are available in some areas for those who prefer to keep their feet dry. Supplies and technical support are provided by sponsoring organizations to help communities coordinate their efforts. Registration Register above to count yourself in!
