Illicit Discharge Detection and Elimination, IDDE, is a common method Durham County Stormwater and Erosion Control uses to address issues regarding substances entering our drainage and waterways. County Stormwater is responsible for enforcing the illicit discharge section of the Durham County Stormwater Ordinance, and investigates all complaints received for concerns outside of City limits. 

 If you believe you have observed an illicit discharge, please let us know by calling our Stormwater Hotline at 919-560-7008, or emailing McKenzie Bradshaw at mfbradshaw@dconc.gov. 

 Below is a table with examples of common illicit discharges observed in Durham County.
