Clarendon Hills Water Treatment
Clarendon Hills' current 2026 Water Quality Report says the Village purchases and delivers 100% Lake Michigan water through the DuPage Water Commission; the report covers water provided during calendar year 2025. Windy City Water Pros can help you explore a whole-home setup around your Clarendon Hills home's goals, plumbing, and installation space—not assumptions about conditions at a particular faucet. A utility report describes the public system. It is not a reading from one home's tap, where plumbing, fixtures, sample location, and existing treatment can change the experience.

LOCAL WATER NUMBERS
This report does not publish a hardness figure. Ask us to test your water instead of using a guessed number.
This municipal water-quality report describes the public water system and reported samples. It is not proof of water conditions, contaminants, hardness, plumbing materials, or treatment needs at a specific Clarendon Hills home; building plumbing, service-line material, fixtures, and local conditions can affect an individual property.

HOMES IN THIS AREA
The 2020-2024 ACS estimate puts the median year built for Clarendon Hills housing units at 1982, a late twentieth-century housing era. That is context for discussing plumbing access, fixture age, and updates at a specific address, not a condition report for any one home.

We consider your household priorities, plumbing, and available space before discussing an installation. A municipal report can provide useful context, but it does not by itself determine what a Clarendon Hills home needs.

Clarendon Hills' official 2026 Water Quality Report identifies Lake Michigan as the Village's sole source. It says the Village purchases and delivers 100% Lake Michigan water from the DuPage Water Commission, which purchases finished water from the City of Chicago's Jardine Water Purification Plant.
The Village's current 2026 Water Quality Report summarizes water provided from January 1, 2025 through December 31, 2025. It also states that the Village completed UCMR sampling in 2025 and that no UCMR contaminants were detected in the samples collected.
Not by itself. The report describes the Clarendon Hills public water system and reported samples, rather than conditions at an individual home. Building plumbing, service-line material, fixtures, and local conditions can affect a specific property.
Clarendon Hills' Village report concerns the public water system supplied with Lake Michigan water. If a Clarendon Hills property uses a private well, we discuss well treatment only after laboratory results or a confirmed field test; we do not infer well conditions from the municipal report.
