Illicit Discharge Detection and Elimination Program

An illicit discharge is any discharge that is not stormwater or a discharge that is covered by a South Dakota DENR Surface Water Discharge (SWD) Permit. Sources include improper cross connections between sanitary or industrial sewers and storm sewers, spills that flow into the storm drainage system, and other non-stormwater sources that flow into the storm sewer system.

The City of Watertown has developed and implemented the following regulations and activities to enact procedures to detect and eliminate illicit discharges:

·          Adopted the Illicit discharge section of the Stormwater Ordinance  

      •           “Dump-No-Waste” Hotline – Call 605-882-6202 x29

-         The public should report any observed illicit discharges or illegal dumping to area waterways, the city’s storm sewer system, or areas draining to them.

-         Examples could include dumping used oil into street inlets, dumping restaurant grease traps in parking lots, or tracking sediment into city streets or off the property of a construction site.

·          Storm sewer map included in city’s GIS

·          Illicit discharge Detection and Elimination – procedures for screening, tracing, and removing illicit discharges and illegal connections

·          Spill prevention, household hazardous waste, and sanitary sewer inspections
