Osgood WWTP and Sewers - New Weston, Ohio Wastewater Treatment Plant

Osgood WWTP and Sewers is a municipal wastewater treatment facility located in New Weston, Darke County, Ohio, serving a population of approximately 652 residents. The plant operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater discharges. As a small-scale facility, it plays a vital role in protecting local water quality in this rural agricultural region. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 461.82 thousand gallons per day and an average discharge volume of 302.83 thousand gallons per day, the facility operates well within its capacity. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Ohio Environmental Protection Agency, ensuring compliance with effluent limits. Treated effluent from the plant discharges to a nearby unnamed tributary, which flows into the Upper Wabash River basin. This watershed ultimately drains to the Wabash River and then to the Ohio River, a major tributary of the Mississippi River. The plant's operations help protect downstream aquatic habitats and support the ecological health of the region's waterways.

The plant discharges into a small tributary within the Upper Wabash River basin, which flows into the Wabash River and eventually the Ohio River. This watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides important habitat for migratory waterfowl. The surrounding agricultural landscape means the plant's nutrient removal helps prevent eutrophication in downstream waters.
