CITY OF WHEATON WELLS AND STORAGE STUDY

INTRODUCTION

The City of Wheaton is seeking proposals from qualified engineering firms to conduct a

comprehensive Emergency Well and Storage Expansion Study. The study follows a 2026 Risk-

Based Water System Analysis which identified a critical vulnerability in the City's reliance on the

DuPage Water Commission (DWC) without active countermeasures. It is the intent of the City to

hire a single highly qualified firm that can provide the following services:

• Project Management and Scheduling: Coordinating all aspects of the study within the

2026–2028 capital planning cycle.

• Emergency Well Evaluation: Performing Level 2 constant-rate pump tests and detailed

water quality/blending analysis for all six (6) City wells to determine the costs for

rehabilitation versus full replacement.

• Storage Capacity Cost Analysis: Providing financial modeling for expanding storage

capacity to address current deficits.

• Operations & Maintenance (O&M) Projections: Determining the annual maintenance

costs required to maintain both groundwater wells and additional storage assets in a

state of permanent operational readiness.

• Reporting and Decision Support: Delivering a final roadmap and financial study to guide

the City’s critical 2028 capital investment decision point.

BACKGROUND

The City of Wheaton’s water distribution system serves over 52,000 residents and currently relies

on treated Lake Michigan water purchased from the DWC as its sole active source. A recent 2026

strategic risk analysis conducted by Arcadis U.S., Inc. identified a critical vulnerability: the system

possesses no active countermeasures to mitigate a total supply loss from the DWC. While the

City maintains six emergency groundwater wells, these assets have been tested monthly but have

not been in continuous use since 1992 and require evaluation to determine their operational

viability and compliance with modern Illinois Environmental Protection Agency (IEPA) standards.

Furthermore, the strategic risk analysis identified that the City’s current storage capacity (7.27

MG) is insufficient for its 4.57 MGD average day demand, resulting in a storage deficit of 1.87

million gallons (MG) relative to DWC’s 48-hour minimum storage mandate.

OBJECTIVES

The primary goals of this study, framed as a Water Quality in Emergency Preparedness project,

include, but are not limited to:

• Emergency Well Evaluation: Determine the feasibility, cost, and water quality impacts

of utilizing all six Wheaton wells as primary emergency supply sources for up to 30 days

without full treatment (excluding chlorination).

• Storage Expansion Analysis: Develop a cost-effective roadmap to reach the DWC

required volume of storage (providing a full 48-hour supply).

CITY OF WHEATON WELLS AND STORAGE STUDY

• Long-Term O&M Planning: Project annual maintenance costs for both operational wells

and storage assets to ensure permanent operational readiness.

• Alternate Options: Develop alternate options to address the risk associated with

providing water during a key supplier outage.

SCOPE OF SERVICES TO INCLUDE, BUT NOT LIMITED TO:

Task 1: Technical Assessment of All Wheaton Wells

• Level 2 Pump Testing: Conduct a constant-rate pump test for each of the six wells to

evaluate drawdown, production capacity, aquifer health, and equipment stress.

• Water Quality Desktop Study: Perform a desktop analysis comparing well water samples

against the well supply. This must evaluate disinfection and corrosion control needs, as

well as secondary standards such as Iron, Manganese, and Zinc.

• Blending & Lead Analysis: Analyze the impacts of shifting from surface water to

groundwater, specifically regarding Lead Service Lines (LSLs) and potential water quality

issues impacting public health.

• Rehab vs. Replacement Costing: Provide estimates to rehabilitate legacy equipment

versus full replacement to meet modern IEPA standards.

Task 2: Storage Expansion & Financial Analysis

• Infrastructure Alternatives: Provide high-level options to increase total system storage

to meet requirements.

• Siting Study: Evaluate land acquisition needs or the use of existing municipal sites (e.g.,

Fire Station adjacent to President site).

Task 3: Operations & Maintenance (O&M) Costing

• Upfront Cost: Provide construction costs for additional storage and pumping stations.

• Groundwater O&M: Estimate annual costs for routine monthly testing, sampling, and

chemical (chlorine) system maintenance.

• Storage O&M: Provide a maintenance budget for storage assets, including mixers,

cathodic protection, and recoating.

Task 4: Effective Countermeasure Options

• Risk Mitigation ROI: Provide additional countermeasure options and their respective

returns on investment should the City experience a key supplier outage from the DWC.
