Greg Hoag, Public Works Director
SUBJECT:
Lift Station 7 Pump Purchase
BACKGROUND
At the April 20, 2009 Council Work Session, the pump issues at Lift Station #7 were discussed with
Council. Both of the existing "chopper" pumps are in need of major repair. These repairs are
estimated to cost $11,900 for each pump. The cost to replace each of these pumps with a new
"chopper" pump would be $18,600. Because the cost to repair each pump is well above 50% of the
cost of replacement, it is recommended the pumps be replaced rather than repaired. Staff has
consulted with several pump vendors, as well as an engineer with Bolton and Menk, regarding the
issues with the pumps at this lift station, and regarding an optimal solution. It has been determined
that the "chopper" pumps are not an adequate solution for this lift station. Regular submersible
pumps and an in-line grinder are a better solution to treat the materials being discharged from
Presbyterian Homes.
Based on the above information, Council directed that the purchase of the two 10 HP regular
submersible pumps be placed on the April 27 Council meeting agenda, as part of the overall solution
which involves the installation of an in-line grinder to pre-process the objectionable material being
discharged by Presbyterian Homes.
Staff will be sending a letter to Presbyterian Homes regarding the on-going issues, as well as to
inform them of the payment needed for replacement of the current pumps, as per the agreement.
Staff will also arrange for a meeting with representatives from Presbyterian Homes, the Mayor, and
City Staff to discuss how and where to install an inline grinder, which will be the responsibility of
Presbyterian Homes.
