ITEM SUMMARY:
The West Chicago/Winfield Wastewater Authority (WWCWWA) Regional Wastewater Treatment Plant (WWTP)
operates under an NPDES permit regulated by the Illinois Environmental Protection Agency (IEPA); Permit No.
1L0024369. As authorized by the Clean Water Act, the NPDES Permit Program controls water pollution by
regulating point sources that discharge pollutants into waters of the United States. Water pollution degrades
surface waters, making them unsafe for drinking, fishing, swimming, and other activities. Industrial, municipal, and
other facilities must obtain permits from the IEPA if their discharges go directly to surface waters and must renew
their permits every five years. For years, the USEPA has pressured the IEPA to impose new and stricter nutrient
removal limitations on wastewater treatment plants consistent with national policy. The most recent IEPA NPDES
permit for the WCWWA WWTP expires on April 30, 2027.
Since 2015, the WCWWVA has been a member of one local environmental group, the DuPage River Salt Creek
Workgroup (DRSCW), formed in 2005 in response to concerns about Total Maximum Daily Loads (TMDLs) being
set for the East & West Branches of the DuPage River and Salt Creek, which is made up of local communities,
Publically Owned Treatment Works (POTWs) or WWTPs, and private environmental organizations. The DRSCW
has been working to produce comprehensive data sets for local watersheds to determine and resolve priority
stressors to local aquatic systems. The organization continues to implement targeted watershed activities that
resolve priority waterway problems efficiently and cost effectively. Working directly with the other environmental
groups and the IEPA, the DRSCW has created, submitted, and received support for the implementation of special
permit conditions and stream restoration projects. It is DRSCW’s plan that implementation of its stream restoration
projects will produce the greatest improvement in water quality and habitat for less money than individual POTW
projects. Because of being a member of the DRSCW and paying Project Funding Assessments, participating
POTWs received a temporary reprieve from the IEPA to upgrade its own POTW and comply with strict phosphorus
limits likely to be imposed by the IEPA. The WCWWVA agreement with DRSCW expired on December 31, 2022, at
which time WCVWWA stopped paying Project Funding Assessments. As a result, in WCWWA’s current NPDES
permit, a special condition has been added which states the total phosphorus removal limits of 1.0 mg/l would be
effective Oct 1, 2026.
On December 7, 2020, authorized by Resolution No. 20-R-0076, the Mayor executed a contract with the Donohue
& Associates, Inc. (Donohue) for a Phosphorus Removal Pilot Study at the West Chicago/Winfield Wastewater
Authority (WCWWA) Regional Wastewater Treatment Plant. This Study was completed and the final report was
provided in January 2022. The study recommended four different options to reduce the total phosphorus limits
below 1.0 mg/l. After review of the report and discussions with WWTP contracted staff, the consensus is to
implement an option called “Anaerobic/Anoxic/Oxic (A2O)” to achieve the total phosphorus limits. This option will
also provide the WCWWA with total nitrogen removal, limits for which will be coming down the road. With this
option, the Study shows, WCWWVA can achieve 0.37 mg/l total phosphorus removal limits, which would be
significantly below the 1.0 mg/l. The IEPA has previously suggested more stringent total phosphorus limits

including 0.5 mg/l and 0.1 mg/l. On February 20, 2023, the City Council authorized Resolution No. 23-R-0006
authorizing Donohue to perform all required design engineering services related to the AZO Phosphorus Removal
Project.
On May 20, 2024, the City Council authorized Resolution No. 24-R-0045 to approve a Contract with Independent
Mechanical Industries of Elk Grove Village, Illinois, for the A2O0 Phosphorus Removal Project at the West
Chicago/Winfield Wastewater Authority Regional Wastewater Treatment Plant in an amount not to exceed
$5,015,000.00. The Project scope of work includes physical modifications to the existing aeration basins, pulled air
mixing system, electric actuators, pumps, diffusers and other necessary items. Please note, the current Project
scope was reduced significantly to stay within budget. The major cuts included removing Return Activated Sludge
(RAS) pumps, chemical polishing system, and modified electrical scope. By implementing the reduced Project
scope, WCWWA can achieve 0.6 mg/l total phosphorus removal limits, which would be below the 1.0 mg/l.
The construction on this Project began in fall 2024 and was suspended through the winter 2024-25 season. The
construction resumed in March 2025. To date, the Project has run into some unforeseen circumstances as well as
some necessary changes that are required for completing the Project. To date, ten additional scope of work items
have been identified. The following table summarizes the additional work and its associated costs.
