WICONISCO TWP STP - Advanced Wastewater Treatment in Wiconisco Township, Pennsylvania

WICONISCO TWP STP is a municipal wastewater treatment facility located in Wiconisco Township, Dauphin County, Pennsylvania. The plant serves a population of approximately 1,566 residents, providing advanced treatment to protect local water quality. As a small-scale facility, it plays a vital role in managing wastewater for this rural community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 378.54 cubic meters per day and a discharge volume matching that figure, the facility operates at full capacity. Under the US Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection, ensuring effluent meets strict standards. The treated effluent is discharged into a local waterway, likely a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life and important migratory fish species. Advanced treatment at this plant helps reduce nutrient loading, contributing to the bay's restoration efforts.

The plant discharges into a local stream within the Susquehanna River basin, which ultimately drains into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting a complex ecosystem of fish, crabs, and waterfowl. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making advanced treatment critical for maintaining water quality in this sensitive watershed.
