I. RECOMMENDATION:
Council Approval of an Engineering Task Order with the City Engineer to Sub-Contract with MKN & Associates to Replace the Two Existing Above Ground Pumps and Update the Power Supply at the Existing La Questa Sewer Lift Station.
II. BACKGROUND:
The City is interested in improving the La Cuesta Lift Station located on the corner
of La Cuesta Ave and Phelps Ave in the City of Coalinga, CA. The existing lift station currently has two Gorman- Rupp above grade self-priming pumps located within a removable housing. The housing is located within an open below grade sump which limits operator access. These pumps are beginning to fail and their reliability is diminishing.
The proposed project will replace the existing pumps with solids handling submersible pumps within the existing wet well, provide an updated power supply, and controls. The 70-foot force main will also be replaced as part of the project. Improving the lift stations accessibility and safety will be included in the proposed improvements.
III. DISCUSSION:
MKN will be contracted to provide construction plans and technical specifications for the proposed lift station improvements. Also included are engineering services during construction. A copy of the task order with detailed scope is attached.
IV. ALTERNATIVES:
- Council may choose not to proceed with this project. Staff does not recommend this action as the existing pumps are beginning to fail and need to be replaced.
V. FISCAL IMPACT:
MKN proposes to complete this base work on a time and materials basis with a budget not to exceed $69,683. Therefore, staff is recommending approval of this task order in order to proceed with designing the lift station improvements. There are sufficient project funds in the sewer fund to cover the cost of design and construction. | | |
