New Centerville STP | Secondary Wastewater Treatment in Milford Township, Pennsylvania

New Centerville STP is a municipal wastewater treatment facility located in Milford Township, Somerset County, Pennsylvania. The plant serves a small population of 282 residents in the rural community of New Lexington, operating under the regulatory framework of the United States Clean Water Act. The plant provides secondary treatment, which is the standard level required for most municipal facilities under the National Pollutant Discharge Elimination System (NPDES) permit program. With a designed capacity of 151.42 units and an average discharge volume of 105.99 units, the plant operates below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local waterway that ultimately drains into the Ohio River basin. The plant's operations help protect downstream water quality in the region, supporting aquatic life and recreational uses in the watershed.

The plant discharges into a tributary of the Youghiogheny River, which flows into the Monongahela River and then the Ohio River. This watershed supports diverse aquatic species and provides drinking water for downstream communities. The secondary treatment process reduces organic pollutants and suspended solids, helping maintain the ecological health of the receiving waters.
