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 VVWTP 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.
