Ostrander WWTP and Sewer System - Secondary Treatment Plant in Ostrander, Ohio

Ostrander WWTP and Sewer System is a municipal wastewater treatment facility located in Ostrander, a village in Delaware County, Ohio, United States. The plant serves a small population of around 500 people, reflecting the rural character of the area. It is situated inland, far from coastal waters, and its operations are part of the broader wastewater infrastructure managed by local authorities. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for most municipal facilities. With a designed capacity of 340.69 million gallons per year and an actual discharge volume of 121.13 million gallons per year, the plant operates well below its capacity, indicating room for future growth. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a stream or river within the Scioto River watershed, which ultimately drains into the Ohio River and then the Mississippi River. This discharge supports the local aquatic ecosystem and downstream water quality. The plant's compliance with EPA NPDES permits ensures that environmental standards are maintained.

The plant discharges into a tributary of the Scioto River, which flows into the Ohio River and eventually the Mississippi River. The local watershed supports diverse aquatic life, including fish and macroinvertebrates, and is part of a larger basin that provides drinking water and recreational opportunities downstream. The plant's secondary treatment helps protect water quality in this inland system.
