Hampden Township Roth Lane STP - Pennsylvania Wastewater Treatment Plant

Hampden Township Roth Lane STP is a municipal wastewater treatment facility located in Hampden Township, Cumberland County, Pennsylvania. Serving a population of about 38,285, the plant is part of the region's infrastructure managed by the local municipality. The plant's location in the Susquehanna River basin places it within a watershed that ultimately drains to the Chesapeake Bay. As a US facility serving a medium-sized agglomeration, the plant is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Pennsylvania Department of Environmental Protection. These permits set effluent limits based on technology and water quality standards, typically requiring at least secondary treatment for municipal plants of this scale. The plant's design capacity and treatment processes are managed to comply with these regulatory requirements. The treated effluent from the plant is discharged into local waterways that flow into the Susquehanna River, a major tributary of the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and important fisheries. The plant's operations contribute to protecting water quality in this sensitive downstream environment.

The plant discharges into the Susquehanna River basin, which drains into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay supports a rich ecosystem including blue crabs, oysters, and migratory fish. Nutrient and sediment loads from wastewater plants in the basin are a key concern for bay health, making treatment performance critical for downstream water quality.
