Amanda WWTP and Sewer System - Secondary Treatment Plant in Ohio

The Amanda WWTP and Sewer System is a municipal wastewater treatment facility located in Amanda, Fairfield County, Ohio, United States. It serves a small population of 707 residents, reflecting the rural character of the community. The plant operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment as the minimum standard for municipal wastewater plants. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 378.54 thousand cubic meters and an annual discharge volume of 264.98 thousand cubic meters, the facility operates below its capacity, indicating room for future growth. The plant is not within 10 km of the coast, classifying it as an inland facility. The treated effluent is discharged into a local waterway that ultimately drains into the Ohio River basin. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic life and providing drinking water for millions. The plant's operations contribute to protecting downstream water quality in this ecologically significant watershed.

The plant discharges into a local stream that flows into the Hocking River, a tributary of the Ohio River. The Ohio River basin supports a variety of fish species and provides habitat for migratory birds. Downstream, the river joins the Mississippi River, which empties into the Gulf of Mexico. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf.
