Rantoul Eastside STP is a municipal wastewater treatment facility located in Rantoul, Illinois, serving a population of about 27,379. The plant is situated in Champaign County, an inland area of the state, and is part of the region's wastewater infrastructure. As a medium-sized agglomeration, the plant is expected to provide secondary treatment under the U.S. Clean Water Act. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Illinois Environmental Protection Agency, governs its discharge limits and monitoring requirements. The plant's design capacity and treatment processes are consistent with facilities of this scale. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant plays a key role in protecting downstream water quality, including the Kaskaskia River and the larger Mississippi River system, which supports diverse aquatic life and provides drinking water for communities.

The plant discharges into tributaries of the Kaskaskia River, which flows into the Mississippi River. The Mississippi River basin is a major ecological corridor supporting fish, migratory birds, and other wildlife. The plant's operations help maintain water quality in this important watershed, reducing nutrient and pollutant loads that could affect downstream ecosystems.
