What is an Illicit Discharge?
IDDE Pic 2

An illicit discharge is defined as any unauthorized discharge other than clean stormwater released into the Municipal Separate Storm Sewer System (MS4). Illicit connections may be intentional or may be the result of connections made years ago when water quality issues were not a concern.

The types of illicit discharges vary widely with some examples being:

  • Waste oil, antifreeze, paint, trash or other household chemicals
  • Car wash, laundry, and industrial wastewaters
  • Pool water discharge (chlorinated and dechlorinated)
  • Spills on roadways and other accidents
  • Failing septic systems and illegal dumping practices
  • Improper disposal of sewage from recreational practices such as boating or camping

Common indicators of illicit discharges include abnormal odors, strange colors, or oil sheen present around or inside storm inlets or pipes. Keeping harmful substances out of our water benefits everyone; environmentally and economically.

Please report suspected pollution and illicit discharges directly to the Borough Offices at 717-684-2467.
