Illicit Discharge Detection and Elimination (IDDE) Projects

goal of IDDE is to improve water quality by identifying and eliminating contaminated, non-stormwater discharges entering stormwater drainage systems and discharging to surface waters. Illicit discharges contribute to the degradation of local receiving waters and can pose a public health risk. Among the many types of illicit discharges that have been identified in Vermont, sanitary wastewater is generally considered as having the greatest impact. Other types of illicit discharges we have encountered include graywater connections (washwater from laundry machines, sinks, dishwashers, etc.), mop water and oil dumping via floor drains and catchbasins, pet waste and trash dumping, vehicle washing runoff, and (infrequently) industrial discharges. Municipal water leaks are also frequently discovered.
