New Madison WWTP and Sewers - Advanced Wastewater Treatment in Ohio

New Madison WWTP and Sewers is a municipal wastewater treatment facility located in New Madison, Darke County, Ohio. The plant serves a small population of approximately 1,025 residents, providing essential sanitation services to this rural community in the western part of the state. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 492.10 megaliters and an annual discharge volume of 272.55 megaliters, the plant operates well within its capacity. As a US facility, it is regulated under the Clean Water Act through an NPDES permit issued by the Ohio Environmental Protection Agency, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Great Miami River, a tributary of the Ohio River. This river system supports diverse aquatic life and provides drinking water for downstream communities. The advanced treatment level helps minimize nutrient loading and protects the ecological health of the receiving waters.

The plant discharges into tributaries of the Great Miami River, which flows into the Ohio River and eventually the Mississippi River. This watershed supports diverse fish populations and provides habitat for migratory birds. The advanced treatment reduces nutrient pollution, helping to prevent algal blooms and maintain water quality in downstream ecosystems.
