IRVING STP - Irving, Illinois Wastewater Treatment Plant

IRVING STP is a municipal wastewater treatment plant located in Irving, Montgomery County, Illinois. The facility serves a small population of 665 residents and operates as part of the local infrastructure managed by the village of Irving. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 264.98 megaliters and an annual discharge volume of 189.27 megaliters, the plant operates below its capacity, indicating adequate treatment capacity for the community. The treated effluent is discharged into local waterways that eventually drain into the Mississippi River basin. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's aquatic habitats.

The plant discharges into receiving waters that flow into the Mississippi River basin, a major watershed that drains much of the central United States. The downstream environment supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the overall health of the Mississippi River ecosystem.
