The storm water utility was created to construct, maintain and manage the storm water facilities in Grand Chute to meet the discharge limits for total suspended solids and phosphorus set by the EPA and Wisconsin DNR. A specific property may not require its own storm water facility but many of the public ditches drain to detention ponds. These ponds prevent flooding on both public and private property and improve the quality of the runoff before it is discharged into the lakes and streams. The average cost to purchase property and construct a pond can range from $300,000 to $700,000.
