The City of Waukee Stormwater Department takes great pride in the quality of stormwater management that is provided by the city. The city currently manages 110 miles of storm pipe, 3,969 stormwater intakes and 1,641 stormwater manholes. The Stormwater Utility was created to ensure that appropriate resources are available to manage the stormwater within the city and provide a stable funding source to maintain compliance with the MS4 permit required by IDNR.
The Clean Water Act, enforced by the U.S. Environmental Protection Agency's (EPA) National Pollutant Discharge Elimination System (NPDES) permit program, was designed to control water pollution throughout the United States by regulating point and non-point sources of pollution to our country's waterways. The Iowa Department of Natural Resources (IDNR) is tasked on the state level to enforce the US EPA NPDES storm water regulations through a permitting process. Under the program, the City of Waukee is required to hold and maintain a Municipal Separate Storm Sewer System (MS4) NPDES Phase II Permit.
What is Stormwater? Stormwater is the flow of water that results from precipitation and which occurs immediately following rainfall or as a result of snowmelt. When a precipitation event occurs, several things happen to the water. Some of the precipitation infiltrates into the soil surface, some is taken up by plants, and some is evaporated into the atmosphere. Stormwater runoff is the remainder of the precipitation that flows off land surfaces and impervious areas into storm sewers and drainage ways.
