Yorkville WSTP
Water Source Transfer Plan (WSTP)
Cornwell Engineering Group, Inc.
May 2026
Overview
Phase 1 of the WSTP in 2019 and 2020 focused on analyzing and understanding the existing water
quality in the Yorkville water distribution system as well as DuPage purchased water.
Phase 2 provided the corrosion control demonstration to establish optimized corrosion control
treatment (OCCT) with orthophosphate. The two major testing components were screening the
options by evaluating lead solubility, then harvested pipe through flow tests were conducted to
define optimum dosages of orthophosphate as compared to the delivered DuPage water.
This Phase 3 evaluates the other water quality considerations related to delivering appropriately
treated water and providing education and communications supporting awareness and a positive
public perception of the Water Source Transfer Plan. The first eight (8) tasks of this phase are
covered by the Oswego Grant. Tasks 9 through 16 are the responsibility of each grant member,
in this case Yorkville, and will involve additional work and coordination by Cornwell Engineering
Group and Engineering Enterprises, Inc. (EEI) including coordinating with applicable work items
in the Grant contract for Tasks 1 through 8.
Below is a description of each task.

Task 9: Modeling Flow Changes in The Distribution System, and
Task 10: Planning UDF Flushing for Flow Direction Changes in the
Distribution System
Task 9 requires modelling flow direction in the distribution system, particularly highlighting areas
of the system with changes in flow direction. EEI will run the actual model using the existing
model of the City's water works system in Bentley WaterGEMS, with participation from Cornwell
in understanding the model and advising on model runs to assist the planning.
Task 10 is planning the UDF program based on the model results. Cornwell will serve as an advisor
on this task with EEI doing the actual model runs in conjunction with our recommendations. Our
role will be advising on areas needing flushing, flushing plan and schedule before, during, and
after the water source transition, velocities to use, monitoring to conduct and consulting on order
of flushing. We are also going to engage Confluence Engineering, a nationally known expert in
distribution flushing.
Task 11: Plan Emergency Wells
While wells will be removed from routine service, they will remain available for emergency use. The
WSTP will define:
CORNWELL 2`r
ENGINEERING GROUP
• Wells that will remain available
• Conditions under which emergency wells may be activated
• Operational protocols for reintroduction into the system
• Water quality monitoring requirements during routine sampling, both while wells are not in
use/not being pumped to system (being pumped to waste for routine well testing and
sampling), and during emergency use (wells being pumped to system)
• Coordination procedures with IEPA prior to activation
• Procedures will be established to prevent unintended operation
Tasks 12-14: Finalization
Tasks 12-14 includes developing the final WSTP based on information developed under the grant and
the work directly with Yorkville (this contract). Internal review will take place, corrections made and the
report will be delivered to IEPA. Necessary IEPA interaction is included.
Task 1S: Implement UDF
Yorkville will conduct the flushing program. Cornwell will be available for consultation, data review and
progress meetings.
Implement Water Switch
This is not part of the WSTP and is optional. If desired Cornwell can be available during the water switch
for real time discussions on the implementation findings, sentinel home results etc.
Also, after the water switch IEPA will require a new IDSE. Cornwell can assist with or conduct the new
IDSE as needed.
If desired we can discuss these tasks prior to the water switch.
Yorkville/EEI Responsibilities.
EEI will provide model runs on detention times for various flow scenarios for the future
distribution system (Task 1) with assistance from Cornwell on prescribing the recommended
model runs and data needed. WQ modeling is not required but if available will be requested. The
end product will be the future estimated system detention times.
For the UDF program, EEI will work with us on model runs. This includes current flow patterns
and flow patterns and detention times after the switch. Yorkville/EEI will be responsible for the
actual valve changes needed etc. to conduct the flush program and will conduct the flushing. .
Yorkville/EEI will need to provide DuPage water for tasks 1, 4, 5 and 6 and pipes if the iron pipe
