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 136.2 miles of storm sewer in our system with 2,197 manholes, 5,045 intakes, 1,158 flared end sections and 580 subdrain cleanouts. The Stormwater Utility was created to ensure that appropriate resources are available to manage the stormwater within Waukee and to provide a stable funding source to maintain compliance with the MS4 permit required by the Iowa Department of Natural Resources (DNR).
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 U.S. by regulating point and non-point sources of pollution to our country’s waterways. The Iowa DNR is tasked on the state level to enforce the U.S. EPA NPDES stormwater 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 is 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.
