Brown Township Reedsville STP - Pennsylvania Wastewater Treatment Plant

Brown Township Reedsville STP is a municipal wastewater treatment facility located in Brown Township, Mifflin County, Pennsylvania. Serving a population of about 4,658, the plant is part of the region's infrastructure for managing domestic wastewater from the Reedsville area. As a US-based facility, the plant operates under the regulatory framework of the Clean Water Act, administered through the National Pollutant Discharge Elimination System (NPDES) permit program. For plants of this scale, typical treatment includes secondary biological processes to meet effluent limits set by the Pennsylvania Department of Environmental Protection. The plant discharges treated wastewater to a local water body, which ultimately drains into the Susquehanna River basin and then to the Chesapeake Bay. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic life and requiring nutrient reduction efforts to maintain water quality.

The plant's treated effluent enters a local stream that flows into the Juniata River, a tributary of the Susquehanna River. The Susquehanna River is the largest river feeding the Chesapeake Bay, a vital estuary that supports diverse aquatic species and is a key migratory corridor for fish and birds. Nutrient management is critical in this watershed to prevent eutrophication and protect downstream ecosystems.
