Manchester WWTP and Sewer System - Advanced Wastewater Treatment in Manchester, Ohio

Manchester WWTP and Sewer System is a municipal wastewater treatment facility located on Fair Avenue in Manchester, Adams County, Ohio. Serving a population of 2,043, the plant provides advanced treatment to protect local water quality in the Ohio River basin. The plant operates under the US Clean Water Act, which requires NPDES permits for all discharges. With a designed capacity of 1,135.62 thousand cubic meters and an annual discharge volume of 870.65 thousand cubic meters, the facility maintains a utilization rate consistent with small community systems. Advanced treatment ensures high effluent quality, reducing nutrients and pathogens before discharge. The treated effluent enters a tributary of the Ohio River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems, including the Ohio River's diverse fish populations and the Mississippi River's delta region.

The plant discharges into a tributary of the Ohio River, part of the Mississippi River basin that drains into the Gulf of Mexico. This watershed supports diverse aquatic life, including freshwater mussels and migratory fish. The advanced treatment helps reduce nutrient loading, which is critical for preventing hypoxic zones in the Gulf.
