K. Singh & Associates, Inc. (KSA) was retained by the Division of State Facilities, which is part of the State of Wisconsin’s Department of Administration, to prepare a sewer reconnection design study on the State Fair Park Fairgrounds. The City of West Allis is upgrading their sanitary sewer system on South 77th Street and as a result, State Fair Park will lose its connection to the sanitary sewer system for its Wisconsin Exposition Center, the Milwaukee Mile infield restrooms, and the “gray water” connections for the southern portion of the Milwaukee Mile bleachers in 2011. The Department hired KSA to conduct a concept design study that connects the Wisconsin Exposition Center and the grandstands of the Milwaukee Mile to an existing facility. In all, there is a total of about 200-lineal feet of sewer on this project.
As part of the design process, a flow monitoring study was performed during the 2009 State Fair, August 6, 2009 to August 16, 2009 to determine peak flow in the sanitary sewers that may be used for diversion. Flows coming from the southeastern portion of the Wisconsin Expo building, the Milwaukee Mile infield restrooms, and the “gray water” connections for the southern portion of the Milwaukee Mile bleachers were also measured.
The preliminary engineering report provided three alternatives to connecting the sewer system to existing facilities located within the fairgrounds and make recommendations for the implementation of the most cost effective alternative.
Final design plans were prepared that will reconnect the sewer to an existing line north of the current location as well as install a new lift station.
