Newport WSD WWTP and Sewer System - Secondary Treatment Plant in Newport, Ohio

Newport WSD WWTP and Sewer System is a municipal wastewater treatment facility located at 149 Merchant Lane in Newport, Ohio, within Washington County. The plant serves a small community of approximately 975 residents, reflecting its role as a local infrastructure asset for this rural area in the Appalachian region of southeastern Ohio. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits for biochemical oxygen demand and total suspended solids. The facility has a designed capacity of 340.69 volume units and reports a discharge volume of 302.83, indicating it operates below its design capacity. The treated effluent is discharged into a local water body that ultimately drains into the Ohio River watershed. The Ohio River flows westward to join the Mississippi River, which empties into the Gulf of Mexico. The plant's operations help protect downstream water quality in this ecologically significant river system, which supports diverse aquatic life and provides drinking water for millions.

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 is ecologically important, supporting diverse fish species and providing habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting downstream aquatic ecosystems from eutrophication and oxygen depletion.
