Please include the following item on the City Commission Agenda for consideration at the October 22, 2013 meeting:
Set a Bid Date of November 19, 2013 for Bid Number B1359, Project UT1102KA Kaw WTP Raw Water Intake Replacement
Project Description
The project provides for the construction of a redundant surface water intake and raw water pipeline to the Kaw Water Treatment Plant (WTP), and modifications to and dredging in the area of the active intake as recommended in the November 2012 Kaw Water Treatment Plant Raw Water Intake Evaluation by Black & Veatch. The construction of the new intake and raw water pipeline will provide a redundant point of raw water diversion from the Kansas River for the Kaw WTP. These facilities will also serve as the first phase of Kansas River raw water supply required for the potential expansion of the Kaw WTP to a treatment capacity of 25 MGD. The modifications to the existing intake involve raising the top to above the new water surface as impounded by Bowersock Dam, installing a sediment shield on the intake pipe to reduce the intake of sand into the pipe and Low Service Pump Station No.2, and dredging in the immediate area of the intake. Additionally the two (2) abandoned intakes and piping will be removed. See the attached map indicating the location of the work.
