Jeannette City STP - Municipal Wastewater Treatment in Penn, Pennsylvania

Jeannette City STP is a municipal wastewater treatment facility located in Penn, Westmoreland County, Pennsylvania. The plant serves a population of around 10,129 residents, placing it in the medium-agglomeration category for US wastewater infrastructure. It is situated inland, more than 50 kilometers from the Atlantic coast, and discharges into local waterways within the Ohio River basin. As a US facility, Jeannette City STP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. For plants serving populations of this scale, secondary treatment is the standard requirement, with additional nutrient removal possible depending on the receiving water body's sensitivity. The plant's design capacity and treatment process details are not publicly available in this dataset. The treated effluent from the plant ultimately flows into the Ohio River watershed, which drains into the Mississippi River and then the Gulf of Mexico. The local streams and rivers support diverse aquatic life and are part of a larger network that provides drinking water and recreational opportunities for communities downstream. Protecting water quality in this basin is critical for both ecological health and human use.

The plant discharges into local tributaries of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River basin supports a wide variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Downstream water quality is influenced by nutrient loads from wastewater and agricultural runoff, making effective treatment important for preventing eutrophication in the Gulf of Mexico's hypoxic zone.
