In conjunction with DuPage County, Naperville Township is statutorily required to be in full compliance with the Illinois Environmental Protection Agency (IEPA). Specifically, we are required to follow the 2021 Dupage County Stormwater Management Program Plan to ensure that the water discharged is environmentally safe.
