Illicit Discharge

MCM 3: Illicit Discharge Detection & Elimination (IDDE)

Illicit discharges are any type of flow found in a storm sewer system that is not composed entirely of stormwater. These flows are a major source of water pollution, occur during dry-weather conditions, and can be much more toxic to stream ecosystems because the pollutant is not diluted by stormwater. These discharges can enter the system through illegal connections, intentional dumping, accidental spills, or through cracks in stormwater pipes. Sewage contamination can occur when a resident or business owner makes an illegal connection into the stormwater system. Eliminating these illicit flows into our waterways is a key component of the township’s strategy to improve water quality.

Note: Discharges resulting from fire-fighting activities and those that are authorized under another NPDES permit are not considered to be illicit.

The township public works department plays an active role in inspecting all of the pipe outfalls discharging stormwater into local streams. If an illicit discharge is suspected, attempts are made to locate and eliminate the source of the illegal flow. However, we cannot monitor outfalls on a daily basis, so enlisting the help of residents and community members is critical in detecting events of illegal discharges. Through both the PEOP and PIPP campaigns, West Lampeter Township will encourage citizens to report any signs of illicit discharges into the storm sewer system to the Township as soon as possible.

If you see or suspect an illicit discharge contact the Township immediately by phone 717-464-8019 or by email
