NORRISTOWN MUN WASTE AUTH - Norristown, Pennsylvania Wastewater Treatment Plant

NORRISTOWN MUN WASTE AUTH is a municipal wastewater treatment facility located in Norristown, Montgomery County, Pennsylvania, along the Schuylkill River Trail. Serving an estimated population of 59,281, the plant is part of the region's critical water infrastructure, supporting the suburban Philadelphia area. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. For a population of this scale, secondary treatment is the minimum standard, with potential nutrient removal requirements to protect the Chesapeake Bay watershed. The plant discharges into the Schuylkill River, a major tributary of the Delaware River, which flows into Delaware Bay and ultimately the Atlantic Ocean. The Schuylkill River provides drinking water for Philadelphia and supports diverse aquatic life, including migratory fish species. The plant's location in an urbanized area underscores its role in maintaining water quality in a densely populated watershed.

The plant discharges into the Schuylkill River, which flows southeast to join the Delaware River near Philadelphia. The Delaware River then empties into Delaware Bay, a major estuary on the US East Coast. The Schuylkill River is a critical water source for Philadelphia and supports a variety of fish and wildlife, including American shad and striped bass. The watershed faces challenges from urban runoff and combined sewer overflows, making effective wastewater treatment essential for downstream ecological health.
