RUSHVILLE STW - Rushville, Illinois Wastewater Treatment Plant

RUSHVILLE STW is a municipal wastewater treatment facility located in Rushville, Schuyler County, Illinois. Serving a population of about 3,229, the plant is part of the town's infrastructure for managing domestic wastewater. As a small agglomeration, it plays a key role in maintaining public health and environmental quality in the region. Under the US Clean Water Act, wastewater treatment plants of this scale are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permitting program. The plant's discharge is regulated by the Illinois Environmental Protection Agency, which sets effluent limits to protect water quality in the receiving water body. The treated effluent from RUSHVILLE STW ultimately drains into the Illinois River watershed, which flows into the Mississippi River and then to the Gulf of Mexico. This connection highlights the plant's role in reducing nutrient and pollutant loads that could contribute to downstream issues such as hypoxia in the Gulf.

RUSHVILLE STW discharges into a tributary of the Illinois River, which is part of the larger Mississippi River basin. The Illinois River supports diverse aquatic life and is an important migratory corridor for fish and waterfowl. Downstream, the Mississippi River carries water to the Gulf of Mexico, where nutrient pollution from upstream sources contributes to seasonal hypoxic zones. The plant's treatment helps mitigate local impacts on the immediate water body and contributes to broader watershed health.
