New Paris WWTP and Sewer System - Advanced Wastewater Treatment in Ohio

The New Paris WWTP and Sewer System is a municipal wastewater treatment facility located in New Paris, Preble County, Ohio, United States. It serves a population of approximately 1,620 residents, classifying it as a small-scale treatment plant under typical US regulatory frameworks. The plant is situated inland, away from coastal influences, and operates under the jurisdiction of Ohio's environmental regulations. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 1,211.33 thousand gallons per day and an actual discharge volume of 647.31 thousand gallons per day, the plant operates well within its capacity. As a US-based plant, it is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting, which sets strict effluent limits to protect water quality. The treated effluent from the New Paris WWTP is discharged into a local waterway that ultimately drains into the Ohio River basin. The Ohio River is a major tributary of the Mississippi River, which flows into the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the regional watershed.

The New Paris WWTP discharges into a local stream that is part of the Great Miami River watershed, which flows into the Ohio River and eventually the Mississippi River and Gulf of Mexico. The plant's advanced treatment reduces nutrient and pollutant loads, helping to prevent eutrophication and maintain water quality in downstream rivers. The region supports diverse aquatic life, including fish species such as smallmouth bass and various freshwater mussels, which benefit from reduced contaminant inputs.
