Approve Purchase and Installation of Improvements to Lift Stations 17, 20, 21, 22, 26, and 27
end
Executive Summary
Staff has been in the process of upgrading older lift stations as the pumps and motors wear out. These improvements are included in annual Capital Improvement Program budgets.
This action approves the purchase and installation of improvements to six different lift stations by Electric Pump for an estimated amount of $345,476.75 plus a requested 10% contingency to allow for unanticipated issues during the projects.
Background
In 2018, staff went through a process to improve system efficiency, reduce redundancy and standardize equipment with a single pump manufacturer. A primary focus was to find a system that was better able to handle ‘flushables’ that cause clogging.
After researching all manufacturers’ newest products it was determined that only the Flygt N style submersible pump provided the combination of material cutting and clog free operation that was being sought. This pump includes a hard iron impeller and the company provides a two-year clog free guarantee on their products. No other manufacturers were able to provide a competitive bid that met the equivalent specifications. The local distributor for this product is Electric Pump. Council approved standardizing on this pump manufacturer for system efficiency
The following are the Lift Stations being considered for improvement, the issues of concern, and proposed work:
Lift Station 17
Work includes replacement of both pumps, guiderails, base elbows, discharge piping, and VFD controls for improved electric efficiency. The existing pumps are of different horsepower resulting in an unbalanced load. Pump #2 has developed a major vibration due to a shaft deflection. This station has also been experiencing regular clogging requiring weekly response. Estimated replacement cost is $39,376.75.
Lift Station 20
Work includes the addition of a grinder pump and motor control center to manage the floating mat comprised of ‘flushable’ wipes and grease. Additionally base elbows and discharge piping are deteriorating requiring replacement. This station has also been experiencing regular clogging requiring weekly response. Estimated replacement cost is $84,525.00.
Lift Station 21
Work includes the addition of a grinder pump and motor control center to manage the floating mat comprised of ‘flushable’ wipes and FOG (fats, oils, and grease). Additionally base elbows, guide rails (replace with stainless steel), discharge piping are deteriorating requiring replacement. The access hatch will be upgraded for clearance and to meet current safety regulations.
This is a major station serving a large portion of the city. The project will require at least five days and the hiring of a company to perform bypass pumping. Estimated project cost is $109,120.00 plus $17,650.00 for bypass pumping.
Lift Station 22
Work includes replacement of both pumps. The majority of appurtenances have been upgraded in the past ten years and are still in good shape. This station is currently running on only one pump as the redundant pump has already failed. Estimated replacement cost is $26,455.00.
Lift Station 26 and 27
Work includes replacement of both pumps and VFD controls for improved electric efficiency. The majority of appurtenances have been upgraded in the past ten years and are still in good shape. LS 26 is currently running on only one pump as the redundant pump has already failed. These two stations are in the air park and are designed for interchangeability of parts. Estimated replacement cost is $34,170.00 for each station.
