SMETHPORT STP - Keating Township, Pennsylvania Wastewater Treatment Plant

SMETHPORT STP is a municipal wastewater treatment plant located in Keating Township, McKean County, Pennsylvania. It serves a population of about 4,521 people, placing it in the small-to-medium agglomeration category. The facility is situated inland, more than 50 km from the Atlantic coast, and discharges into local waterways. As a US-based plant, SMETHPORT STP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. For plants of this scale, secondary treatment is typically required, and permits specify effluent limits for parameters such as biochemical oxygen demand and total suspended solids. The treated effluent from SMETHPORT STP likely discharges into a tributary of the Allegheny River, which flows into the Ohio River, then the Mississippi River, and ultimately the Gulf of Mexico. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's operation is critical for protecting water quality in this region.

SMETHPORT STP discharges into a local stream that is part of the Allegheny River basin. The Allegheny River flows into the Ohio River, which joins the Mississippi River and empties into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems, including fish species such as smallmouth bass and walleye, and provides habitat for migratory birds. The plant's effluent must meet state and federal water quality standards to protect these downstream environments.
