Illicit Discharge Elimination Program (IDEP)

We need your help!

You may not know it but you are an integral part of our Illicit Discharge Elimination Program
and the Development Services Department needs your help spotting illicit discharges
throughout the township.

An illicit discharge is any discharge to our lakes and streams that contains polluting materials,
such as oils, detergents, bacteria and sediment. 

Examples of illicit discharge sources are sanitary sewer outlets, failed septic systems,
illegal dumping, spills, fertilizer runoff and unprotected construction sites.

We are asking you to help us in reducing the number of illicit discharges by reporting
suspicious discharges to either Oakland County or West Bloomfield Township Development

The agency you contact will investigate each complaint and take measures to find and
eliminate the illicit discharge.

Now that you’re ready to help, you may be wondering what to look for and what to report. 
Please use the following chart as a guide.  This is only a guide, if it looks suspicious and
you’re in doubt, don’t hesitate to call.
