MEMORANDUM
TO:
Todd Gerhardt, City Manager
FROM: Paul Oehme, Director Public Works/City Engineer Q 0 .
DATE: February 23, 2009 ~"'n5
SUBJECT: Approve Quote for Well #8 Rehabilitation; Project No. 97-4-2
PROPOSED MOTION
"The City Council is recommended to accept the quotes for Well #8
Rehabilitation, City Project 97-4-2 and award the base bid quote in the amount
of $36,225.00 to Bergerson Caswell, Inc.
City Council approval requires a simple majority vote of the City Council
present. "
BACKGROUND
Annually the City inspects and performs routine maintenance on City wells. Well
equipment is recommended to be serviced approximately every eight years to
extend the life of the pumps and motors. Also, these projects are necessary to
decrease the likelihood of costly emergency repairs and supply interruptions.
The Well Rehabilitation Program identifies the rehabilitation of Well #8 this year.
Well #8 is located on TH 41 east of the Minnewashta Regional Park. This well
has not had major service completed on it for 10 years. The project includes
lowering the pump set in the aquifer an additional 40'" The lowering of the pump
compensates for the lower aquifer levels.
QUOTES
Staff solicited quotes from three qualified well drilling companies. Quotes
received for the work on Well #8 were tabulated; no errors were found in the bid
tabulation. Two alternates were included in the solicitation. Alternate 1 is to
replace and furnish a new pump bowl ass.embly in case the bowl assembly
exhibits a significant amount of wear after inspection. Alternate 2 is to bail and
remove sand from the open well hole. Staff does not think the City will need
either Alternate 1 or 2 at this time; however, this work was included in the
solicitation in case the scope of work needs to be changed after inspection of the
open hole and pump.
The City of 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.
