Sunbury WWTP and Collection System, Olive Green, Ohio | Municipal Wastewater Treatment

Sunbury WWTP and Collection System is a municipal wastewater treatment facility located in Olive Green, Ohio, within Delaware County. The plant serves a population of approximately 4,389 people, classifying it as a small to medium agglomeration under U.S. regulatory frameworks. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. For plants of this scale, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges to a local waterway within the Scioto River basin, which flows into the Ohio River and ultimately the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment essential for environmental and public health.

The plant's discharge enters a tributary of the Scioto River, part of the Ohio River basin. The Scioto River supports diverse fish populations and is used for recreation and drinking water. Downstream, the Ohio River is a major ecological corridor, and nutrient loading from wastewater can contribute to algal blooms and hypoxia in the Gulf of Mexico. Effective treatment helps mitigate these impacts.
