Water Quality

Protection of water quality in creeks, streams, and rivers is everyone’s responsibility and requires cooperation between citizens, governments, and industry.

The Village of Glen Ellyn owns and maintains a storm sewer system that conveys stormwater runoff within the Village to downstream water bodies, primarily the East Branch of the DuPage River. To prevent harmful pollutants from being washed or dumped into the storm sewer, the Village has a permit from the Illinois Environmental Protection Agency (IEPA) and a stormwater management program. The Village’s Stormwater Management Program Plan (SMPP) describes the practices that minimize the discharge of pollutants from the sewer system to the river. The Village and DuPage County prepare an annual inspection report as part of the IEPA permit.

In addition, developers of construction sites greater than 1 acre are required to obtain their own permit from the IEPA and control erosion and sediment from the construction site to reduce pollution in the storm sewer and the downstream water bodies. Smaller sites must adhere to similar requirements as mandated by the DuPage County Stormwater and Floodplain Ordinance.
