Dayton WWTP and Sewer System: Municipal Wastewater Treatment in Dayton, Ohio

The Dayton WWTP and Sewer System is a major municipal wastewater treatment facility located in Dayton, Ohio, serving a population of approximately 278,226 residents. As a large agglomeration under U. S. EPA guidelines, the plant is expected to provide at least secondary treatment under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which regulates discharges to surface waters. The plant operates under the regulatory framework of the U. S. Clean Water Act, administered by the Ohio Environmental Protection Agency. For a facility of this scale, typical treatment includes primary and secondary processes, with potential nutrient removal to protect downstream water quality. The regulatory context ensures compliance with effluent limits. The treated wastewater from the Dayton WWTP 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 critical role in protecting the Great Miami River's water quality, which supports diverse aquatic life and recreational uses.

The Dayton 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 vital waterway for drinking water, industry, and navigation, eventually draining into the Mississippi River and the Gulf of Mexico. The plant's effluent must meet stringent water quality standards to protect these downstream ecosystems.
