Alliance WWTP and Sewers - Lexington, Ohio Municipal Wastewater Treatment

Alliance WWTP and Sewers is a municipal wastewater treatment facility located in Lexington, Stark County, Ohio, serving a population of about 26,253. The plant is situated along the Mahoning Valley Trail and plays a key role in managing wastewater for this community in the northeastern part of the state. As a medium-sized agglomeration, the plant is subject to the U.S. Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting requirements. Typical treatment for facilities of this scale includes secondary treatment, with possible nutrient removal depending on the receiving water body's sensitivity. The plant's design capacity and treatment process details are not publicly available, but regulatory standards ensure compliance with effluent limits. The treated effluent is discharged into the Mahoning River watershed, which flows southeast into the Ohio River and ultimately to the Mississippi River and Gulf of Mexico. The plant's operations help protect local water quality and downstream ecosystems, including aquatic habitats in the Mahoning River.

The plant discharges into the Mahoning River basin, a tributary of the Ohio River. The Mahoning River flows through northeastern Ohio and western Pennsylvania, supporting diverse aquatic life and recreational uses. Downstream, the Ohio River is a major waterway that provides drinking water and habitat for numerous species. The plant's discharge must meet state and federal water quality standards to protect these resources.
