The Illicit Discharge Elimination Program (IDEP) was created through grant funding as an extension of the already successful Surface Water Improvement and Monitoring (SWIM) Team Program. IDEP is charged with the duties of searching out and inspecting illicit discharges in Macomb County. This is accomplished by surveying the open drains, streams, rivers and shorelines in the county and looking for illicit discharges. Suspicious discharges are sampled and investigated. If a problem is found, the county works diligently with the owner of the discharge to correct the problem.

Estimated amount of wastewater prevented from discharging into Macomb County surface waters and Lake St. Clair:
This has been accomplished by the Illicit Discharge Elimination Program:
• Surveying over 745 miles of open drains, including rivers and streams. During these surveys, more than 5130 outfalls were identified and tested.
• Investigating 7134 residential, commercial, industrial and institutional facilities since 1998.
• From these investigations, 1236 or 17% were found to have an illicit discharge. Illicit discharges include failing septic fields or a direct discharge to a river, stream, roadside ditch, ground surface or storm drain. These discharges have either been corrected or are in the correction process.
