Catawissa Boro STP - Secondary Wastewater Treatment in Catawissa, Pennsylvania

Catawissa Boro STP is a municipal wastewater treatment facility located on Railroad Street in Catawissa, Columbia County, Pennsylvania. The plant serves a population of approximately 1,589 residents, classifying it as a small community system within the state's wastewater infrastructure. The plant provides secondary treatment, a standard level required by the US Clean Water Act for most municipal facilities. With a designed capacity of 757.08 thousand gallons per day and an average discharge volume of 264.98 thousand gallons per day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a nearby water body that ultimately drains into the Susquehanna River basin, which flows into the Chesapeake Bay. The plant plays a role in protecting local water quality and contributing to the health of the Chesapeake Bay watershed, a major ecological system supporting diverse aquatic life and migratory species.

The plant discharges into a tributary of the Susquehanna River, which flows south through Pennsylvania and Maryland into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports a rich ecosystem of fish, crabs, and waterfowl. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the bay's restoration efforts under the Chesapeake Bay Total Maximum Daily Load (TMDL) program.
