Lift Station No. 24 Rehabilitation, PW055X1: Approve Quote
PROPOSED MOTION
"The City Council approves quote in the amount of $34,346.25 to Quality Flow
Systems, Inc. for piping and pump replacement at Lift Station 24."
City Council approval requires a simple majority vote of the City Council
present.
BACKGROUND
Annually, the City considers replacement of equipment for lift stations that are
old, unreliable or cannot be properly maintained anymore. These replacements are
designed to make the sanitary lift station network more reliable and reduce the
likelihood of emergency calls and the potential for sewer backups. Currently, the
City maintains 31 lift stations in the system. The repairs forthe lift station were
generally identified in the 2008 Sanitary Sewer Comprehensive Plan and have
recently been refined based on recent problems in the system.
DISCUSSION
Staff typically starts work on this annual project later in the year; however, staff is
requesting replacement of piping and a failed pump at Lift Station 24 at this time.
Lift Station 24 is located at the intersection of Lyman Boulevard and Auduboll
Road and is the largest lift station the City maintains. The. station has 4 pumps
which are as large as 90 horse power. The pump which failed is 15 years old and
can no longer be fixed and needs to be replaced. Staff has reviewed the needs of
the station and is requesting to replace the failed pump with a 65 .hors~ power
pump. Staff had programmed this lift station to be rehabilitated in 201 0 with
replacement of pumps but unfortunately one of the pumps did not make it until
next year.

Staff has received two quotes for this work as follows:
Lift Station #24: Piping and Panel
Pump and Piping
Quality Flow Systems, Inc. Braun Pump & Controls
(KSB Pump) (ABS Pump)
$34,346.25 $38,275.75
Another pump for Lift Station 24 is also having problems; however, staffwill try to keep this
pump in service until next year when it is scheduled for replacement.
Staffhad originally programmed to replace equipment at Lift Stations 7 and 9 for this year's lift
station rehabilitation program. Funding for the replacement of the pump and piping at Lift
Station 24 is proposed to come out ofthis project budget so staff may need to delay rehabilitation
of one of the scheduled lift stations until next year.
