Union City WWTP and Sewer System serves the community of Roe Corners in Darke County, Ohio. The plant treats wastewater from approximately 2,000 residents, operating as a small municipal facility in the Midwestern United States. The plant employs advanced treatment processes, which go beyond standard secondary treatment to remove additional nutrients and contaminants. With a designed capacity of 1,514.16 cubic meters per day and an average discharge volume of 870.65 cubic meters per day, the facility operates well within its capacity, ensuring reliable treatment for the community. The treated effluent is discharged into local streams that drain into the Great Miami River watershed, ultimately flowing to the Ohio River and then the Mississippi River system. This inland location means the plant's discharge supports regional water quality and aquatic habitats in the Ohio River basin.

The plant discharges into tributaries of the Great Miami River, which flows southwest to the Ohio River and eventually the Mississippi River. This watershed supports diverse aquatic life, including fish species such as smallmouth bass and channel catfish. The advanced treatment helps protect downstream water quality in this agriculturally intensive region of western Ohio.
