Pilot Grove East WWTP - Secondary Treatment Plant in Pilot Grove, Missouri

Pilot Grove East WWTP is a municipal wastewater treatment facility located on Bellair Road in Pilot Grove, Cooper County, Missouri. The plant serves a small population of 384 residents, reflecting its role in a rural community within the United States. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 227.12 megaliters per year and an actual discharge volume of 185.49 megaliters per year, the facility operates below its capacity. As a U.S. plant, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Missouri Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed, part of the larger Mississippi River basin. This downstream connection highlights the plant's role in protecting regional water quality and aquatic ecosystems in the central United States.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic life and is part of a major migratory corridor for birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this agriculturally intensive region.
