Overview
Dunkirk WWTP and Sewer System is a secondary treatment plant serving 952 people in Dunkirk, Ohio. It discharges treated wastewater into local waterways, supporting the region's water quality.
Dunkirk WWTP and Sewer System is a municipal wastewater treatment facility located in Dunkirk, Hardin County, Ohio. The plant serves a small population of 952 residents, providing essential sanitation services for this rural community in the Midwestern United States. The plant operates at the secondary treatment level, which is the standard requirement under the U.S. Clean Water Act for municipal facilities of this scale. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is approximately 530 million gallons per year, matching its current discharge volume, indicating full utilization of its treatment capacity. The treated effluent from the plant is discharged into local streams that are part of the Scioto River watershed. The Scioto River flows southward to join the Ohio River, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in this agriculturally intensive region of Ohio.
Environmental context
The plant discharges into tributaries of the Scioto River, which flows through central Ohio before joining the Ohio River. The Scioto River supports diverse aquatic life, including fish species such as smallmouth bass and channel catfish, and provides habitat for migratory waterfowl. The watershed is predominantly agricultural, so the plant's nutrient removal helps mitigate eutrophication risks in downstream water bodies.
