Columbiana Co Beaver Local WWTP - Advanced Treatment Plant in Columbiana County, Ohio

Columbiana Co Beaver Local WWTP is a municipal wastewater treatment facility located in Columbiana County, Ohio, United States. The plant serves a population of approximately 2,745 people, primarily from the Beaver Local Schools area and surrounding community. It is an inland facility, situated away from coastal zones, and operates within the Ohio River basin. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the U.S. Clean Water Act. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) or other tertiary processes to meet stringent water quality standards. The facility has a designed capacity of 378.54 cubic meters per day and discharges a similar volume, indicating full utilization. As a U.S. plant, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Ohio Environmental Protection Agency, which sets effluent limits to protect receiving waters. The treated effluent from the plant is discharged into a local waterway that ultimately drains into the Ohio River, a major tributary of the Mississippi River system. The Ohio River supports diverse aquatic life and provides drinking water for millions of people downstream. The plant's advanced treatment helps reduce nutrient loading, which is critical for controlling algal blooms and maintaining water quality in the Mississippi River Basin and the Gulf of Mexico.

The plant discharges into a tributary of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River watershed supports diverse aquatic species and is a vital drinking water source. Advanced treatment at this plant helps reduce nutrient pollution, mitigating hypoxic conditions in the Gulf of Mexico.
