APPROVED BY CITY ADMINISTRATOR: Michael L. Guttman SIGNATURE,
ITEM SUMMARY:
Within the Fiscal Year 2021 Water Fund Budget, money has been included for professional engineering
design services related to the Booster Station #8 Rehabilitation Project (construction anticipated in Fiscal
Year 2022). 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, which is accomplished with pumps at the booster station that operate based on
water system pressure. As more water is drawn or needed from the water distribution system, the overall
system pressure drops. Booster stations are used to maintain system pressure, fill water towers, and
provide water to fight fires. The site/property containing Booster Station #8 also contains Well Station #8
and Well Station #9.
Booster Station #8 and Well Station #8 (shallow well) were initially constructed together in 1989. Well
Station #9 (deep well) was constructed in 1993. No major improvements have been completed at
Booster Station #8 since its original construction. Well Station #8 was rehabilitated in 2020 and Well
Station #9 was rehabilitated in 2018. After more than 31 years of service life, improvements are
warranted at Booster Station #8; the electrical system and motor control equipment is antiquated and
unreliable.
Anticipated improvements associated with the Booster Station #8 Rehabilitation Project (Project) will
include, but are not limited to, the following:
e Replacement of three existing 75 HP pumps and associated piping and valves.
Replacement of existing well control panels.
Replacement of generator controls.
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.
Please note that the existing on-site 0.5 MG ground storage tank also requires improvements, but will be
addressed under a separate Infrastructure Committee agenda write-up.
Trotter and Associates, Inc. (Trotter) of St. Charles, Illinois, has recently completed several projects of
this nature and previously performed design work for the City. Therefore, City staff asked Trotter for an
engineering design proposal for the proposed project. Engineering design services will include, but not
be limited to, coordination with effected agencies (i.e., Illinois Environmental Protection Agency (IEPA)),

permit applications, development of design plans, development of project specifications, and
development of bid documents. Trotter and Associates submitted a cost proposal of $68,900.
It is staff's recommendation that a contract be awarded to Trotter and Associates, Inc. of St. Charles,
Illinois, for engineering design services related to the Booster Station #8 Rehabilitation Project, for an
amount not to exceed $68,900.00.
ACTIONS PROPOSED:
Approve Resolution No. 21-R-0022 authorizing the Mayor to execute a contract with Trotter and
Associates, Inc., in an amount not to exceed $68,900.00, for engineering design services related to the
Booster Station #8 Rehabilitation Project.
COMMITTEE RECOMMENDATION:
Pending recommendation from the Infrastructure Committee at its meeting on April 1, 2021.
