Illicit (Non-Storm Water) Discharges

SCDOT's storm water system consists of ditches, swales, pipes, curbs, catch basins and other drainage features that are designed to collect or convey storm water. If you observe something other than storm water discharged into SCDOT's storm water system, this may be an "illicit discharge" to our system.

Illicit discharges may be a cause of water pollution, SCDOT is committed to identify and eliminate them through the Storm Water Management Program. These discharges can be a public health concern, cause unpleasant odors, and harm aquatic life.
