The Village water system is comprised of 285 miles of water main, 7 pumping stations, and 10 reservoirs. Generally, each station has a motor control center (MCC) which turns the motors on and off, a relative number of pumps, metering equipment, and basic telemetry systems for communication.
Over the course of the last 18 months, there have been a total of 4 pumps and 1 MCC failure ahead of the planned Capital Improvement Plan's (CIP) replacement schedule. One failed pump replacement was brought to the Engineering & Public Works Committee in September, another is only in need of a rebuild and will be handled with operating budget funds. The final two pumps and MCC are included in this item.
The following table represents the station and associated failed equipment along with replacement costs related to the item.

Currently, each failed pump has a second redundant pump that is operational. To maintain system integrity, staff recommends expeditiously replacing the equipment.
The unbudgeted project expenses will be funded through a transfer of $181,740.80 from the Water Well 15 Rehabilitation Project (20025-20-230) to the Water Station Electrical Improvements-Pumps and Motor Replacement –All Stations Project (22028-20-230). The remaining unbudgeted expense for this project in the amount of $359,712.76 will be temporarily used from the general reserves of the Utility Fund in order to initiate a Purchase Order to the vendor. The $359,712.76 expense will be realized in FY 2022/23. A summary of these expenditures and transfers is represented in the budget table.
Staff is recommending F.H. Paschen be awarded this project due to their final product's quality, the speed work is completed, reduced project timelines, communication, design cost savings, and documentation from their project management team.
