Now, choose the SOURCE of your Public Utility's water.

Michigan’s abundant surface water is one of the state’s most remarkable features. In addition to the Great Lakes, which contain one-fifth of the Earth’s surface freshwater and over 3,000 miles of shoreline, Michigan holds over 11,000 inland lakes and ponds, and 36,000 miles of streams. These ample freshwater resources are used by the state’s residents and visitors for business, entertainment, and as a source of drinking water.
