Set a bid date of September 13, 2011 for Bid No. B1135; Priority Group II of Project UT0919CS General Wastewater Pumping Station Improvements. Bid documents to be available Friday August 26, 2011

Consistent with the City Commission’s direction during the 2011 Budget discussions, Department of Utilities Staff continue to monitor and control expenses in relation to actual revenues. As these are evaluated, sources of Capital Project Funding are being identified to carry out the City Commission’s stated goal of executing priority Capital Projects even in the current economic climate. The reasons for executing this project are outlined in the memo below.

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. The vac-prime lift stations included in Priority Group II of the General Wastewater Pumping Station Improvements are identified on the attached map.

Project Status:

Professional Engineering Consultants have completed the design and production of construction documents for the pump stations included in Priority Group II incorporating all City Staff comments on the plans and specifications. Final documents will be available for bidding by August 26, 2011. All property interests have been secured and all required permits have been issued for the project.

Affected commercial property owners will be contacted by City Staff prior to the start of construction to ascertain and address any concerns related to the project. A public meeting will be held for affected residential property owners following the award of the contract to introduce the contractor and City staff involved in the project, provide an overview of construction activities and projected schedule, and to address any concerns residents may have related to the project.

Project Schedule

A total of three pump stations are included in Priority Group II, PS12, PS22, and PS27. The bid documents allow for 150 calendar days to attain substantial completion and 180 calendar days to attain final completion from the notice to proceed. The contractor may elect to mobilize and commence construction on a single or on multiple locations in accordance with the terms and conditions set forth in the project specifications.
