Willowbrook water treatment

Water Softener and Filtration in Willowbrook, IL

Willowbrook's current official Consumer Confidence Report says the Village purchases Chicago water through the DuPage Water Commission, and that Chicago uses Lake Michigan as its source water. We use that published system context as a starting point, then discuss your home, plumbing, goals, and installation options without assuming conditions at your address. 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.

Town FAQ source: Village of Willowbrook 2025 Consumer Confidence Report (2025)

Where does Willowbrook's municipal water come from?

Willowbrook's current official report says the Village purchases Chicago water through the DuPage Water Commission. The report says Chicago uses Lake Michigan as its source water.

What does the Willowbrook report say about the water connection?

The report states that Willowbrook purchased approximately 337 million gallons of Chicago water from the DuPage Water Commission through a 20-inch supply main connected directly to the Commission's supply grid.

Does Willowbrook's report tell me what is happening in my home's water?

No. It describes the public water system and reported information, not conditions at a specific Willowbrook property. Plumbing, service-line material, fixtures, and on-site conditions can differ, so the report is not a home diagnosis.

What does the current report say about monitoring and reporting violations?

Its 2025 monitoring and reporting violations section describes Consumer Confidence Rule adequacy/availability/content and Lead and Copper Rule notification violations, as well as the Village's stated corrective actions. That report statement does not determine conditions at an individual home.
