The Illicit Discharge, Detection, and Elimination (IDDE) Program identifies and removes illicit connections and discharges from the Multiple Storm Sewer System, which includes road ditches and storm sewers in Calumet County. Public participation is vital to the county’s illicit discharge program in detecting and reporting illegal and unusual discharges and spills to road ditches and storm sewers. View the Illicit Discharge Manual (PDF) or Chapter 18 of the Code of Ordinances (PDF).
