APPROVE FINAL PLANS AND AUTHORIZE BIDS -
MOLINE WATER TANK PAINT PROJECT
PROJECT 98-06
Proposed Action.
Staff recommends adoption of the following motion: Move that Council approve plans.
as presented. and authorize bids for the rehabilitation and paintinQ of Moline water
tanks. Proiect 98-06.
Overview.
The Moline water tower was last painted in 1987. The steel tank is showing significant
signs of corrosion. The current capital improvement plan (CIP) includes this year 2000
project with an estimated cost of $500,000. In August, 1999 City Council authorized
design of this project. A detailed interior inspection and thorough review of underwater
video taping has shown that there is enough corrosion to warrant complete repainting.
The engineer's estimate of construction cost is $665,575. The increase is primarily due
to safety and venting rehabilitation work that is also included in the project. The plans
are completed and are now presented to Council for approval and ordering of bids.

Analysis of Issues.
. Description of Improvements
. Complete corrosion control and painting of interior and exterior of tank with
antennas and cable in-place using necessary containment system. The
interior surfaces of the ground tank shows 40 - 50% requiring repainting. The
elevated tank interior surfaces shows 20 - 25% corroded areas.
. Install new tank vents
. Install new overflow pipes
. Install new electrical wiring and lighting
. Install new exterior ladder and roof platform
. Hopkins lettering
. Paint color and graphics
Staff is recommending the tank exterior be painted the same color as the Minnetonka
Ridgedale Tank with vertical Hopkins uppercase lettering in blue located on three
sections of the tank wall. The existing tank has black uppercase lettering on two
sections of the tank wall and the Hopkins logo on two sections.
. Project Schedule
The project schedule is as follows:
Open bids:

Final completion:

. Impact on water distribution system
The water system will be more susceptible to minor pressure fluctuations due to the
elevated storage being reduced in half. However, past history has shown that
pressures will be maintained by the Blake elevated tank. In the event of a fire flow
event, we can open a valve to the Minnetonka system to maintain pressure. The water
tanks will not be taken out of service until the water filter work is completed at the Elmo
Treatment plant.
