Wasco Sanitary District STP - Campton Hills, Illinois Wastewater Treatment Plant

Wasco Sanitary District STP is a municipal wastewater treatment facility serving the community of Campton Hills in Kane County, Illinois. The plant treats wastewater from approximately 1,685 residents, reflecting a small-scale operation typical of rural or suburban agglomerations in the Midwest United States. The plant employs advanced treatment processes, which exceed the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 2,081.97 thousand cubic meters and an annual discharge volume of 639.74 thousand cubic meters, the facility operates well within its capacity. As a US facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Illinois Environmental Protection Agency, ensuring compliance with federal water quality standards. The treated effluent is discharged into a local water body that ultimately drains into the Fox River watershed, which flows into the Illinois River and then the Mississippi River. This downstream chain supports diverse aquatic life and provides water for communities and agriculture. The plant's advanced treatment helps protect water quality in this ecologically significant basin.

The plant discharges into a tributary of the Fox River, which flows through northeastern Illinois before joining the Illinois River. The Illinois River is a major tributary of the Mississippi River, supporting a rich ecosystem including fish, waterfowl, and migratory birds. The watershed is ecologically sensitive due to agricultural runoff and urban development, making advanced treatment crucial for maintaining water quality and preventing nutrient pollution downstream.
