LEHIGH CO A HEIDELBERG HGHTS STP - Heidelberg Township, Pennsylvania Wastewater Treatment Plant

LEHIGH CO A HEIDELBERG HGHTS STP is a municipal wastewater treatment facility located in Heidelberg Township, Lehigh County, Pennsylvania. The plant serves a small community of approximately 925 residents, operating under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level required for most municipal facilities under the National Pollutant Discharge Elimination System (NPDES) permit program. With a design capacity of 378.54 m³/day and a discharge volume matching that figure, the facility operates at full capacity, treating wastewater from the local area before discharge. The treated effluent is released into a local waterway that ultimately drains into the Delaware River Basin, supporting downstream ecosystems. The plant plays a key role in protecting water quality in the region, particularly for small streams and tributaries that feed into larger rivers.

The plant discharges into a local stream within the Delaware River Basin, which flows into the Delaware River and eventually to the Delaware Bay. This watershed supports diverse aquatic life, including fish species such as American shad and striped bass. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this ecologically sensitive region.
