RE:

Set Bid Date for Project UT1304 Contract 4 Wakarusa Wastewater Treatment Plant and Conveyance Corridor

 

Background/Project Description

The 2012 Wastewater Utilities Master Plan and Capital Improvements Program recommend the construction of the Wakarusa Wastewater Treatment Plant (WWTP) and Conveyance Corridor facilities to be online in 2018.  These improvements are required to mitigate wet weather surcharging of sanitary sewers along the 31st Street Corridor, provide for relief of wet weather overloading at the existing WWTP, and provide additional organic treatment capacity to provide for future growth of the community.

 

The Conveyance Corridor improvements include a pump station facility in the area of 31st and Louisiana and required force mains and gravity sewers to convey sewerage to and from this point to the Wakarusa WWTP.

 

The City Commission received a detailed project update at the January 6, 2015 meeting.

 

Project Status

Construction contracts for the WWTP site fill, access roads, and force mains were bid and awarded in 2014.

 

UT1304 Contract 4 includes the Wakarusa WWTP, Pump Station 10, and improvements to the existing Kansas River WWTP. These three separate facility sites were grouped into one construction contract due to the similar equipment specified and the related coordination. Having one general contractor will reduce project costs and avoid scheduling conflicts. A list of interested local subcontractors will be gathered and provided at the pre-bid conference.

 

Project Schedule
