Millersport WWTP and Sewer System | Small Municipal Plant in Ohio

Millersport WWTP and Sewer System is a wastewater treatment facility located in Millersport, Ohio, serving a population of about 1,010 people. The plant is situated in Walnut Township, Fairfield County, and is part of the local municipal infrastructure managed by the village. As a small-scale treatment plant in the United States, it operates under the regulatory framework of the Clean Water Act, administered by the Ohio Environmental Protection Agency. Facilities of this size typically require secondary treatment as a minimum standard, with NPDES permits governing discharge limits to protect water quality. The plant's treated effluent is discharged into a local water body that ultimately drains into the Ohio River basin. The surrounding area is primarily rural and agricultural, with the plant playing a key role in protecting local streams and groundwater from untreated sewage.

The plant discharges into a tributary of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic life and is important for recreational fishing and drinking water supplies downstream. Protecting this water body from nutrient pollution and pathogens is critical for maintaining ecological health.
