FROM: ,()~. SUBJECT: Well #4 Rehabilitation: Approve Quote for - PW266A DATE: February 22,2010 PROPOSED MOTION "The City Council is recommended to accept the quotes for Well #4 Rehabilitation, PW266A, and award the base bid quote in the amount of $24,313.00 to E.B. Renner & Sons, 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 #4 this year. Well #4 is located in Lake Susan Park. This well has not had major service completed on it for nine years. The project includes lowering the pump set in the aquifer an additional 20 feet refurbishing the motor, reconditioning the pump and replacement of miscellaneous wearing parts. 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 #4 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 assembly 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 I 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. g:\eng\pubIic\pw266a well 4 rehabilitation 20 1 O\accept well rehab quote 022210.doc Chanhassen is a Community for life.
