Sanitary Lift Station #9 Rehabilitation: Approve Quote
PROPOSED MOTION
"The City Council approves a quote in the amount of $41,106.00 to Quality Flow
Systems, Inc. for controls, pumps, and piping replacement at Lift Station #9."
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
worn, unreliable, and impractical to maintain. These replacements are a pro-
active approach designed to make Chanhassen's core collection system more
reliable and less likely to cause costly emergency repairs and potential sewer
backups. The Utility Department currently maintains 31 lift stations inthe
wastewater collections system. Lift Station #9 has been identified as the next lift
station needing rehabilitation.
DISCUSSION
Lift Station #9 is located at 6601 Lotus Trail in Carver Beach. The station's close
proximity to Lotus Lake makes it fundamental that the station be maintained so as
to reduce the likelihood of any wastewater release into the lake. The station has
two 20 hp. pumps, one pump being 12 years old and the other over 30 years old.
Most of the interior piping is original and heavily corroded. The insulation and
check valves should be replaced. The new controls will allow the level of the wet
well to be transmitted and data logged into the City's SCADA system. This is
helpful in diagnosing potential mechanical, as well as, inflow and infiltration
problems.
Staff has received four quotes for the pumps and piping and two quotes for the
controls. All quotes include installation. The quotes for this work are as follows:
The City ot Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

station rehabilitation projects. Their work has been acceptable.
