ITEM SUMMARY:
The City of West Chicago and the Village of Winfield jointly comprise the West Chicago/Winfield
Wastewater Authority (WCWWA), which owns the Wastewater Treatment Plant (WWTP), which
discharges to the West Branch of the DuPage River under NPDES Permit No. IL0023469. The WWTP
receives and processes over five million (5,000,000) gallons of raw sewage daily from both municipalities.
The flow enters the WWTP at two locations. The flow from the City of West Chicago enters the WWTP
through a 36-inch gravity interceptor at the headworks while the flow from the Village of Winfield enters
the WWTP through a 20-inch forcemain into the grit chamber,
On June 19, 2023, the City Council approved Resolution No. 23-R-0052 authorizing the Mayor to award a
construction Contract to Boller Construction Company, Inc. (Boller) for the Headworks Gate Improvement
Project at the West Chicago/Winfield Wastewater Authority Regional Wastewater Treatment Plant in an
amount not to exceed $529,300.00.The scope of work included a project Base Bid for the headworks
gate improvements, including the removal of existing gates and grating, furnishing and installation of a
new stainless steel slide gate and electric actuator, new stainless steel weir gate, new hatches and
grating, spraying protective lining for the concrete headworks structure as well as two of the four primary
clarifiers, and miscellaneous concrete repairs and electrical work.
The project also included an Alternate Bid to spray protective and structural coating to remaining two of
the four primary clarifiers, which was not part of the awarded Contract; however, Boller agreed to hold the
pricing if the Alternate Bid was awarded prior to July 1, 2024. The scope of the Alternate Bid is to prepare
and spray protective and structural coating over approximately 5,600 square feet of wall surface. To
exercise the award of the Alternate Bid was discussed recently with the Village of Winfield staff with a
positive response.
Staff recommends approval of Change Order No. 1 in an amount of $278,800.00. This project is funded
through the WCWWA. The revised substantial completion date will be May 31, 2024, and the revised final
completion date will be June 14, 2024.
