The Schuylkill River became the first scenic river designated in Pennsylvania and one-quarter of the watershed is designated as high quality or exceptional waters. The river and its tributaries have long been recognized for the important roles they play as a fish habitat and source of drinking water. As the largest tributary to the Delaware River, the Schuylkill River is a major contributor to the Delaware Estuary.

The Schuylkill River serves as a natural border between the City of Philadelphia and Lower Merion Township and flows through Fairmount Park, originally established to preserve the water quality in the Schuylkill for Philadelphia’s drinking water supply. Today, many visitors to Philadelphia enjoy the spectacular view of boathouse row, the Fairmount Water Works, and the Philadelphia Museum of Art along the banks of the Schuylkill River. The area of the watershed within Philadelphia is extremely urbanized and includes a diverse mix of neighborhoods, a Center City business district, numerous educational institutions and industrial uses.

Watershed Issues

The Philadelphia Water Department takes a multi-faceted approach to protecting the Schuylkill River watershed and its valuable water resources from the challenges posed by urbanization, and other regional and influences.

What We're Doing

  • Beginning in 2010, PWD will develop an Integrated Watershed Management Plan to guide restoration and preservation within the city portion of the Schuylkill River Watershed.
  • As a key partner, PWD supports the Schuylkill Action Network by providing technical assistance.
  • PWD also participates in the Coalition for Philadelphia’s Riverfronts to support a high quality, continuous, connected riverfront greenway along the Schuylkill and Delaware Rivers. This greenway will contain a multi-use trail and vegetated green space to manage stormwater, protect the rivers from pollution, and attract wildlife back to the riverbanks.
  • The PWD Model Neighborhoods Initiative includes many neighborhoods in the Schuylkill River Watershed, including Manayunk, East Falls, Grays Ferry, Point Breeze, and Allegheny West.
