Urbana Champaign Sanitary District Northeast Sewage Treatment Plant - Urbana, Illinois Wastewater Facility

The Urbana Champaign Sanitary District Northeast Sewage Treatment Plant is a major wastewater facility serving the city of Urbana and surrounding areas in Champaign County, Illinois. With a population served of approximately 92,080, it is classified as a medium-to-large agglomeration under US EPA guidelines. The plant is located at 1118 East University Avenue, Urbana, Illinois. As a US municipal wastewater treatment plant, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, established by the Clean Water Act. This regulatory framework requires secondary treatment as a minimum standard for plants of this size, ensuring effective removal of organic matter and suspended solids. The plant's treatment processes are designed to meet state and federal effluent limits to protect water quality. The plant discharges treated effluent into the local watershed, which ultimately drains into the Mississippi River basin via the Kaskaskia River or the Vermilion River. This region is part of the larger Illinois River basin, supporting diverse aquatic life and providing water resources for communities downstream. The plant plays a critical role in maintaining the ecological health of these waterways by reducing nutrient loads and preventing pollution.

The plant's treated effluent enters the local drainage network, which flows into the Kaskaskia River or the Vermilion River, both tributaries of the Mississippi River. The Mississippi River basin is a major ecological corridor supporting diverse fish, bird, and plant species. Downstream waters are sensitive to nutrient pollution, which can cause algal blooms and hypoxic zones. The plant's compliance with Clean Water Act standards helps mitigate these impacts and protect aquatic habitats.
