The Solution

Uwchlan Township is part of a statewide campaign to combat storm sewer pollution. The Pennsylvania Department for Environmental Protection has developed the following 6 guidelines (Minimum Control Measures) for program development in order to help communities like Uwchlan Township maintain a complete storm water program.

Storm water is everyone's business (PDF), please treat it with respect.

Public Education & Outreach
  • Distributing educational materials and performing outreach to inform citizens about the impacts polluted storm water runoff discharges can have on water quality
  • Controls include:
    • Creating brochures or fact sheets for public distribution
    • Instituting educational programs for school-age children
When It Rains It Drains
Only Rain Down the Storm Drain
Public Participation & Involvement
  • Providing opportunities for citizens to participate directly in program development and implementation
  • Controls include:
    • Organization of community clean-ups
    • Storm drain stenciling
    • Outfall monitoring
    • Citizen watch groups
  • Learn more about the public participation and involvement effort (PDF)
 Illicit Discharge Detection & Elimination
  • Developing a system to detect and eliminate illicit discharges to the storm sewer system
  • Controls include:
    • Promoting recycling programs for commonly dumped wastes
    • Locating and testing suspected problem areas for pollution
    • Informing the public of the hazards of illegal discharges
Construction Site Runoff Control
  • Developing, implementing, and enforcing an erosion and sediment control program for construction activities
  • Controls include:
    • Appropriate site plan review and inspection of new construction and
    • Require implementation of State and County erosion control regulations
  • Get more information about the construction site runoff control (PDF)
Post Construction Runoff Control
  • Creating a program to address storm water runoff from newly developed or redeveloped areas
  • Controls include:
    • Require protection of environmentally sensitive areas (e.g. wetlands)
  • Require recharge of runoff from new impervious surfaces
  • Learn more about post construction runoff control (PDF)
Pollution Prevention & Good Housekeeping
  • This program’s goal is to reduce pollutant runoff from municipal operations
  • Controls include:
    • Regular street sweeping
  • Reduction in the use of pesticides or street salt
  • Frequent catch-basin cleaning
  • Learn more about pollution prevention and good housekeeping (PDF)
What Residents Can Help Watch For
  • Clogged, leaking or overflowing sanitary sewer lines
  • Dry weather flows observed to be contaminated or polluted from outfall pipes into streams (72 hours after a rain storm)
  • Illegal dumping activity into streams or storm sewers
  • Inadequately treated effluent from a sewage treatment plant
  • Observed pollution event or pollutants in stream
  • Sediment leaving a construction site in stormwater
  • Spills, hazardous materials (Chemical, Gas, Oil)
Residents may be the first to recognize "illicit" discharges dumping into storm sewers or coming out of from storm sewer outfalls. If you see an "illicit" discharge please report that to the township by one of the following methods.

Storm Drain Stenciling
Uwchlan Township with the assistance of volunteers has started to mark some of the storm drains in the township with the "No Dumping / Drains to Waterways" stencils. These storm drain stencils educate the public that anything you dump into the storm drain ends up directly in a creek or other public waterway. If you would like volunteer and help with storm drain stenciling: please call the township at 610-363-9450.
