Miamisburg WWTP and Sewer System - Municipal Wastewater Treatment in Ohio

The Miamisburg WWTP and Sewer System is a municipal wastewater treatment facility located in Miamisburg, Ohio, serving a population of about 20,181. The plant is situated in Montgomery County and is part of the region's essential water infrastructure. As a facility serving a medium-sized agglomeration, the plant is subject to the U.S. Clean Water Act and operates under an NPDES permit issued by the Ohio Environmental Protection Agency. Such permits set effluent limits to protect water quality in the receiving water body. The plant's treated effluent is discharged into the Great Miami River, which flows southwest to join the Ohio River near Cincinnati. The Ohio River then drains into the Mississippi River and ultimately the Gulf of Mexico. The plant plays a key role in maintaining water quality in the Great Miami River, which supports diverse aquatic life and recreational uses.

The Miamisburg WWTP discharges into the Great Miami River, a major tributary of the Ohio River. The Great Miami River flows through southwestern Ohio and supports a variety of fish and macroinvertebrate species. Downstream, the Ohio River is a critical waterway for drinking water, industry, and navigation. The plant's discharge must meet state and federal standards to protect these downstream ecosystems and human uses.
