Approve Authorization to Replace Sewage Pumps at Lift Station #6

Purpose:
The purpose of this case is to request authorization to replace the sewage pumps, base elbows and force main pipe located within lift station # 6
Background:
On March 20th the impeller broke on one of the sewage pumps, causing it to malfunction and rendering it inoperable.  Each lift station is equipped with 2 pumps that run alternately.  This allows for increased longevity of the equipment and back up capabilities.     

NA

The malfunctioning pump was replaced with a back-up pump that we keep on hand for emergencies such as this.  The equipment in this lift station was scheduled for replacement in the 2021 Capital Improvement Plan (CIP).  Due to the current situation staff recommends that the replacement take place as soon as possible.   The new pumps quoted for replacement  include an upgrade to a "chopper" style pump that can better handle all the flushable rags, that we are now encountering in our system. Though rags were not the cause of the malfunction, we do frequently have to perform additional maintenance on our lift stations to "derag" pumps.  In addition to replacing the pumps the contractor will replace the base elbows, rail system and force main pipe in the lift station.  To replace the base elbows, portions of the floor in the lift station have to be jack hammered out and the new elbows installed and the concrete re-poured. 

Utility Fund

Staff recommends that the city accept  WW. Goetsch"s bid of $39,612.00 to replace and install new pumps, base elbows, rail system and force main pipe at lift station # 6. This price does not include pump rental of $2,843.00 needed for bypass pumping of the lift station as it is being repaired.

Motion to accept  WW. Goetsch"s bid of $39,612.00 to replace and install new pumps, base elbows and force main pipe at lift station # 6.
