Lift Station No. 24 Pump replacement: Approve Quote
DATE:
SUBJ:
PROPOSED MOTION
"The City Council approves a quote in the amount of $33,349.41 to Electric Pump for
piping and pump replacement at Lift Station 24."
City Council approval requires a simple majority vote of the City Council present.
BACKGROUND
On February 9,2009, the Council approved a quote for replacement of a failed pump at Lift
Station 24. Funding for replacement of this pump came out of the 2009 Lift Station
Rehabilitation CIP project.
DISCUSSION
Another lift station pump has failed at Lift Station 24. Lift Station 24 is located at the
intersection of Lyman Boulevard and Audubon Road and was built in 1995. The failed pump
was an 88 hp pump that was 13 years old. The pump cannot be rehabilitated cost effectively.
The backup pump for list station 10 is currently being used at Lift Station 24. Lift station 24
is the largest lift station in the City. The pumps at this station need to be in good working
condition due to the amount of flow and run time they experience. The station has four
pumps which are as large as 90 hp. Staff has reviewed the needs of the station and is
requesting to replace the failed 88 hp pump with a 65 hp pump. Newer pumps are more
efficient and can offer some of the same pumping characteristics as older larger pumps.
Staff has received three quotes for this work as follows:
Pump and Piping
Quality Flow Systems, Inc.
(KSB Pum )
$39,937.50.25
Braun Pump & Controls
(ABS Pum )
$38,120.89
All the quotes include necessary piping, freight, tax and startup.
Staff had originally programmed to replace the pumps at Lift Station 24 along with some
electrical equipment in 2010. Staffis requesting to advance the replacement of one more
pump to 2009.
