ITEM SUMMARY:
Well #8 Pump Station also known as Booster Station #8, located at 1255 Helena Drive, is one of the City’s
two booster stations, with associated ground storage tanks, used to increase available water in the
distribution system during peak demand periods. The station was originally constructed in 1960 and had its
last mechanical upgrade in 1992. After more than 32 years of service life, additional improvements are
needed. On April 5, 2021, the City Council approved Resolution No. 21-R-0022 authorizing the Mayor to
execute a contract agreement with Trotter and Associates, Inc. (TAI) of St. Charles, Illinois, for design
services related to the Well #8 Pump Station Rehabilitation Project (Project). Due to potential budgetary
constraints the Project was strategically divided into parts consisting of a base bid consisting of critical
components and alternate bid items that could be done as standalone projects at a later date. The scope of
the base bid includes:
Replacement of three existing 75 HP pumps and associated piping and valves.
Replacement of existing well control panels.
Addition of variable frequency drives on the three new 75 HP pumps.
Replacement of pump starters in the existing motor control cabinet (MCC).
SCADA improvements to incorporate changes and upgrade Programmable Logic Controller (PLC).
Electrical system improvements/upgrades as determined necessary.
Roof Replacement.
The alternate bids include:
ALTERNATE ONE: Replacement of onsite generator and associated controls.
ALTERNATE TWO: New interior paint systems and coatings.
The Project was advertised for bids in the Daily Herald as well as on QuestCDN (an online bidding
platform) on January 31, 2025. Bids were opened on February 26, 2025. Two bids were received (bid tab
attached) with Dahme Mechanical Industries Inc. of Arlington Heights, Illinois, submitting the lowest
responsible bid of $1,490,664.00.
