West Mansfield WWTP and Sewer System - Advanced Treatment Plant in Ohio

West Mansfield WWTP and Sewer System is a municipal wastewater treatment facility located in West Mansfield, Ohio, serving a small community of about 700 people. The plant is situated in Logan County, within the Bokescreek Township, and operates under the regulatory framework of the United States Clean Water Act. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 302.83 megaliters per year and an actual discharge volume of 227.13 megaliters per year, the plant operates below its capacity, indicating room for future growth. As a US plant serving fewer than 10,000 people, it is subject to EPA NPDES permitting requirements, which mandate compliance with water quality standards. The treated effluent is discharged into local streams that are part of the Scioto River watershed, which ultimately drains into the Ohio River and then the Mississippi River. The plant plays a key role in protecting the water quality of these downstream water bodies and the aquatic ecosystems they support.

The plant discharges into tributaries of the Scioto River, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. The local watershed supports diverse aquatic life and provides habitat for fish and macroinvertebrates. Advanced treatment helps minimize nutrient loading and protects downstream water quality in this agriculturally influenced region.
