RESOLUTION AWARDING CONTRACT FOR WATER TREATMENT
PLANT HIGH SERVICE PUMP VARIABLE FREQUENCY
DRIVE PROJECT FOR THE CITY OF AMES,IOWA
WHEREAS, the new Water Treatment Plant includes a high service pump station that
allows the facility to pump treated drinking water into the distribution system. This supplements
the high service pump station at the old plant site, increasing redundancy and resiliency in the
event of a disaster and providing a more consistent and even pressure in the water distribution
system; and,
WHEREAS, when pumps are suddenly started or stopped it causes a change in the water
distribution system pressure. The rapid pressure swings contribute to rusty water calls and, if
severe enough, can cause water main breaks. By installing a variable frequency drive (VFD) on a
pump,the pump speed can be slowly ramped up or down,thereby dampening the pressure swings.
It also allows the pump to be run at less than its full speed, allowing the operators to more closely
match the demand from customers. This in turn minimizes the need to frequently start and stop the
pumps; and,
WHEREAS, this project will provide and install a new VFD unit to control one of the
existing high service pumps at the Water Treatment Plant. This work also includes all the required
connections, electrical equipment, and integration services needed to allow the operation of the
VFD through both the existing plant control system and operation in a manual mode. A bid
alternate was requested to purchase a second VFD should the budget allow.The FY 2022/23 Water
Plant Facility Improvements CIP includes $75,000 for this project; and,
WHEREAS, while both base bids received were below the Engineer's Estimate, the total
cost to accept the base bid plus the bid alternate for either proposal exceeded the authorized budget.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Ames, Iowa,
that awarding contract for Water Treatment Plant High Service Pump Variable Frequency Drive
Project to Electric Pump of Des Moines, Iowa, in the base bid only amount of$59,395 is hereby
approved.
