North Lebanon Jonestown STP - Union Township, Pennsylvania Wastewater Treatment Plant

North Lebanon Jonestown STP is a municipal wastewater treatment plant located in Union Township, Lebanon County, Pennsylvania. It serves a population of approximately 3,360 residents, classifying it as a small-scale facility within the state's wastewater infrastructure. As a US-based plant, it 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 small agglomerations like this, secondary treatment is typically required to meet effluent standards. The plant's treated effluent discharges into local streams that flow into the Susquehanna River, which ultimately drains into the Chesapeake Bay. This connection places the plant within a watershed of significant ecological importance, supporting diverse aquatic life and contributing to the bay's nutrient management efforts.

The plant discharges into tributaries of the Susquehanna River, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse fish, shellfish, and bird populations. Nutrient and sediment loads from upstream sources are a key concern for bay health.
