Divernon Treatment Facility | Secondary Wastewater Plant in Divernon, Illinois

The Divernon Treatment Facility is a municipal wastewater treatment plant located on Ping Road in Divernon, Sangamon County, Illinois. It serves a small population of approximately 1,200 residents, typical of a rural community in the central part of the state. The plant operates under the U.S. Clean Water Act framework, which requires secondary treatment for municipal facilities discharging to surface waters. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 605.66 thousand gallons per day and an average discharge volume of 427.75 thousand gallons per day, the facility operates below its capacity, indicating adequate headroom for current demand. As a small agglomeration, it is subject to U.S. EPA National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged to a local receiving water body, likely a tributary of the Sangamon River, which flows into the Illinois River and ultimately the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's operation helps maintain the ecological health of the Sangamon River basin by reducing nutrient and pathogen loads.

The Divernon Treatment Facility discharges into a small stream that drains into the Sangamon River, a major tributary of the Illinois River. The Sangamon River flows through central Illinois, supporting fish populations and recreational activities. Downstream, the Illinois River joins the Mississippi River, a critical migratory corridor for birds and aquatic species. The plant's secondary treatment reduces organic pollution and suspended solids, helping to protect water quality in this agriculturally influenced watershed.
