Middleburg Boro STP - Advanced Wastewater Treatment in Middleburg, Pennsylvania

Middleburg Boro STP is a municipal wastewater treatment facility located in Middleburg, Snyder County, Pennsylvania. Serving a population of approximately 2,758, the plant provides advanced treatment to protect public health and the environment. The facility is situated inland, away from coastal areas, and operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. With a designed capacity of 1,741.28 thousand gallons per day and a current discharge volume of 794.94 thousand gallons per day, the facility operates below its capacity, indicating room for future growth. As an advanced treatment plant, it likely incorporates nutrient removal or other tertiary processes to meet stringent permit limits. The treated effluent is discharged into local streams that flow into the Susquehanna River, a major waterway draining into the Chesapeake Bay. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life and important migratory corridors. The plant's advanced treatment helps reduce nutrient loading, contributing to the bay's restoration efforts.

The plant discharges into local tributaries of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting a rich ecosystem of fish, crabs, and waterfowl. Nutrient pollution from wastewater is a key concern, and advanced treatment helps mitigate algal blooms and hypoxia in the bay.
