Kincaid WWTP and Collection System - Secondary Treatment in Illinois

Kincaid WWTP and Collection System serves the village of Kincaid in Christian County, Illinois. This municipal facility treats wastewater from a small population of 1,461 residents, operating under the regulatory framework of the U.S. Clean Water Act. The plant provides secondary treatment, which is the standard level required by the U.S. EPA for municipal wastewater facilities. With a designed capacity of 946.35 megaliters and an annual discharge volume of 567.81 megaliters, the plant operates well within its capacity. As a small inland facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River Basin. This watershed supports diverse aquatic life and provides water resources for communities downstream. The plant's operations help protect local streams and rivers from untreated wastewater pollution.

The plant discharges into a tributary of the Sangamon River, which flows into the Illinois River and then the Mississippi River. This watershed supports a variety of fish and wildlife, including migratory birds along the Mississippi Flyway. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream water quality in this agriculturally intensive region.
