LOMBARD VILLAGE OF Wastewater Treatment Plant, Glen Ellyn, Illinois

LOMBARD VILLAGE OF is a projected wastewater treatment plant located in Glen Ellyn, Illinois, within DuPage County. The facility is designed to serve a population of 1,900, reflecting a small-scale municipal system typical of suburban communities in the Chicago metropolitan area. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits for biochemical oxygen demand and total suspended solids to protect receiving water quality. The treated effluent from the plant discharges into the local watershed, which ultimately drains into the Des Plaines River and then to the Illinois River, a major tributary of the Mississippi River. This connection highlights the plant's role in safeguarding downstream aquatic ecosystems and regional water quality.

The plant discharges into a watershed that feeds the Des Plaines River, which flows into the Illinois River and eventually the Mississippi River. This river system supports diverse aquatic life and provides habitat for migratory fish species. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water bodies from eutrophication and maintaining ecological balance in the region.
