Please include the following item on the City Commission Agenda for consideration at the August 28, 2012 meeting:

Award the construction contract for Bid No. B1238; Pump Station 15 Reconstruction Project UT0919CS General Wastewater Pumping Station Improvements to the low bidder EmCon, Inc. in the amount of $395,339.00 and authorize the City Manager to execute the contract.

Project Description:

The Department of Utilities budgets a yearly fund for the ongoing maintenance, repair, and, when necessary, replacement of existing wastewater pumping stations within the collection system.

Project Details:

The Department of Utilities operates a number of small (80 to 300 gpm) vac-prime wastewater lift stations to convey sewage to its wastewater treatment plant. These lift stations were installed by the development community to provide service to localized areas of development. The lift stations are typically located in utility easements adjacent to or surrounded by residential property. The existing stations are 15 to 40 years old, many have exceeded their useful lives, are unsafe to maintain as several of the lift stations are classified as confined space entry, many are no longer supported by the original manufacturer and require replacement to bring them up to current KDHE minimum design standards.

The general intent of the project is to replace a number of the existing vac-prime lift stations with rail-mounted submersible pumps, valve vault, overflow prevention, backup power connection and flow metering in order to meet current KDHE minimum design standards. Some modifications to the existing gravity lines upstream of each station may be required. The Department of Utilities will provide wet well level instrumentation, programmable logic controllers and programming. Pump Station 15 is the last of the vac-prime lift stations included for reconstruction as part of the General Wastewater Pumping Station Improvements and is identified on the attached map.
