Illicit Discharge Detection & Elimination

Illicit discharges are generally any discharge into a storm drain system that is not composed entirely of storm water. Illicit discharges are a problem because storm water generally flows to waterways without any additional treatment.

Use this online form to report a suspected illicit discharge.

Examples of improper physical connection to the storm sewer system include:

  • floor drain or household grey-water drain (laundry or sink drain) that is connected to a storm drain
  • a septic tank discharge pipe that is connected to a storm drain or drains directly into a waterway or an improper connection between a storm sewer and sanitary sewer
