VANPORT TWP STP - Vanport Township, Pennsylvania Wastewater Treatment Plant

VANPORT TWP STP is a municipal wastewater treatment plant located in Vanport Township, Beaver County, Pennsylvania. It serves a population of about 8,151 people, classifying it as a small to medium-sized facility under the US Clean Water Act framework. The plant operates under the US National Pollutant Discharge Elimination System (NPDES), which requires secondary treatment as a baseline for municipal facilities. Plants of this scale typically employ conventional activated sludge or similar biological treatment to meet permit limits for biochemical oxygen demand and total suspended solids. The treated effluent is discharged to a receiving water body that ultimately flows into the Ohio River, a major tributary of the Mississippi River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's location inland and away from coastal areas reduces direct marine impact, but its discharge contributes to the overall nutrient and pollutant load in the Ohio River basin.

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 ecosystems, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's effluent contributes to the nutrient load in the river system, which can affect downstream water quality and contribute to hypoxic zones in the Gulf.
