The Township's storm drainage system is very important to keeping runoff from flooding roadways and damaging property. The inlets in the streets are interconnected by piping and eventually discharged to a larger pipe, to a stream or ditch. Eventually all of our runoff ends up in the Brandywine Creek, which drains into the Delaware River.
Inlets are spaced along a roadway with
most located at low points of the street in order to efficiently
collect rainwater. Residents may help themselves by insuring that
the opening is free and clear of leaves and other debris prior to
a rain storm. If the inlet is clogged and not accepting runoff,
the Public Works Department should be notified at (610) 436-5108
Ditches and Swales
Streams and drainage ditches/swales are also conveyors of the runoff. Dumping or raking leaves and other garden debris into these channels hurts the environment and seriously impacts drainage down stream. This action is prohibited by Township Ordinance and the regulations of the Pennsylvania Department of Environmental Protection

National Pollutant Discharge Elimination System (NPDES Permit)
As part of the Clean Water Act, the U.S. Environmental Protection Agency (EPA) has developed stormwater management regulations to improve water quality. The Township was required to apply for a National Pollutant Discharge Elimination System (NPDES) permit which is administered through the Pennsylvania Department of Environmental Protection (DEP). This permit is a 5-year program which began in 2003. The permit is broken up into 6 control measures which include: Public Outreach and Education, Public Participation and Involvement, Illicit Discharge Detection & Elimination, construction site stormwater runoff control, Post-Construction Storm Water Management in New Development and Redevelopment, and Pollution Prevention and Good Housekeeping for Municipal Operations and Maintenance.
This website was set up to address some of these issues and communicate with Township residents and businesses about different things that effect stormwater. If you have any additional questions, please contact Mark Lucas at (610) 610-436-5108 or
Minimum Control Measures
Operators of a Phase II-regulated small municipal separate storm sewer system (MS4) are required to include six minimum control measures in its stormwater management program to meet the conditions of its National Pollutant Discharge Elimination System (NPDES) stormwater permit:
Illicit Discharge Detection and Elimination
Construction Site Runoff Control
Post Construction Runoff Control
Pollution Prevention/Good Housekeeping
If you have a complaint about stormwater, erosion, or sedimentation, please contact Mark Lucas.
