Smithfield WWTP and Sewer System - Advanced Treatment in Smithfield, Ohio

The Smithfield WWTP and Sewer System is a municipal wastewater treatment facility located in Smithfield, Jefferson County, Ohio, United States. Serving a population of 867, this plant is part of the community's essential infrastructure for managing domestic wastewater. The plant operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for discharges into surface waters. As an advanced treatment facility, it goes beyond secondary treatment to remove additional pollutants, ensuring high-quality effluent. The plant's designed capacity of 416.39 units indicates it has reserve capacity for future growth. The treated wastewater is discharged into a local waterway, ultimately contributing to the Ohio River basin. This plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's aquatic habitats.

The plant discharges into a local receiving water body that flows into the Ohio River, a major tributary of the Mississippi River. The Ohio River watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for migratory birds. The advanced treatment level helps minimize nutrient loading and protects downstream ecosystems from eutrophication.
