Stormwater Management:


In March, 2006, the DeWitt Charter Township Board of Trustees approved Watershed Management Plans for both the Looking Glass River and the Grand River.  Approximately 70% of the land area within the Township flows into the Looking Glass River with the remaining area flowing into the Grand River.  The Plans were developed by working with our neighboring municipalities and local stakeholders through a series of public meetings. View the Plans by clicking on the links below:

In an effort to make residents aware of how local actions affect local water quality, the Township has begun a curb marker installation program in local subdivisions. These colorful curb markers stating "No Dumping, Drains to Waterways" are affixed on storm water catch basins to remind people that what goes into these catch basins end up draining into the Looking Glass River and the Grand River.  Motor oil, grass clippings, paint, soaps and chemicals from washing cars, excess lawn fertilizer, and animal waste are all examples of pollutants that hurt water quality in our area. Volunteer groups are working with the Township to install the markers. If your neighborhood or volunteer group is interested in helping install markers, please contact the Manager's Office at (517) 668-0270 or by email at


The Township, working with other municipalities in the Lansing region, has developed a series of informative brochures and news articles for residents and businesses on easy ways they can help improve the water quality in the Looking Glass and Grand Rivers. These cards are available for download by topic by clicking below or can be requested from the Township by email at



What is an illicit discharge?  All water that goes into a storm pipe, catch basin, or drainage ditch within DeWitt Charter Township eventually travels into the Looking Glass or Grand River Watersheds. An illicit discharge is defined as any discharge to the municipal separate storm sewer system that is not composed entirely of storm water, except for discharges allowed under an NPDES permit or waters used for firefighting operations.  These non-stormwater discharges occur due to illegal connections to the storm drain system from commercial, residential, or other establishments.

As a result of these illicit connections, contaminated wastewater enters into storm drains or directly into local water ways without receiving treatment from a wastewater treatment plant.  Illicit connections may be intentional or unknown to the property owner.  An example of an illicit connection is when floor drains are connected to the storm drainage system.  Additional sources of illicit discharges are failing septic systems, illegal dumping practices, and the improper disposal of sewage from recreational practices such as boating or camping.  Illicit discharges also can be generated by persons using antiquated methods for tasks such as cleaning pool filters, cleaning paint brushes, cars, washing and other common activities.

If you happen to see something entering or exiting a storm pipe, catch basin or drainage ditch that looks, smells or feels like something other than stormwater, please contact the Clinton County Drain Commission at (989)224-5160.
