Upper Hanover Macoby Creek STP - Advanced Wastewater Treatment in Pennsylvania

Upper Hanover Macoby Creek STP is an advanced wastewater treatment facility located in Upper Hanover Township, Montgomery County, Pennsylvania. The plant serves a population of approximately 2,000 residents, providing essential sanitation services to this suburban community within the Delaware River basin. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 567.81 cubic meters per day and a discharge volume of 567.81 cubic meters per day, the facility operates at full capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection, ensuring compliance with water quality standards. The treated effluent is discharged into Macoby Creek, a tributary of the Perkiomen Creek, which flows into the Schuylkill River and ultimately the Delaware River and Delaware Bay. The plant plays a key role in protecting the health of these water bodies, supporting aquatic life and recreational uses downstream.

The plant discharges into Macoby Creek, part of the Perkiomen Creek watershed, which drains into the Schuylkill River and then the Delaware River and Delaware Bay. This region supports diverse aquatic ecosystems, including migratory fish species such as American shad. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the Delaware Estuary.
