Springfield WWTP and Sewer System - Ohio Wastewater Treatment Plant

The Springfield WWTP and Sewer System is a municipal wastewater treatment facility located in Springfield, Clark County, Ohio. It serves a population of approximately 85,000 people, classifying it as a medium-to-large agglomeration under U. S. regulatory frameworks. The plant is situated inland, over 50 kilometers from the nearest coast, and its operations are governed by the U. S. Clean Water Act. As a facility serving over 10,000 people, the plant is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements, which mandate secondary treatment as a minimum standard. Typical plants of this scale employ activated sludge or similar biological treatment methods to meet permit limits. The treated effluent from the plant is discharged into receiving waters that ultimately flow into the Ohio River, a major tributary of the Mississippi River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant plays a critical role in protecting water quality in the region by reducing pollutant loads before discharge.

The plant discharges into local streams that drain into the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports a variety of fish and wildlife species, including several state-listed species of concern. The plant's operations help maintain water quality in a region characterized by agricultural and urban runoff pressures.
