A water main break sent water pouring into basements along South Claremont Avenue in Chicago's Heart of Chicago neighborhood Wednesday morning, flooding about a dozen homes and forcing some families to evacuate. Firefighters went door to door checking on residents as the Water Department worked to shut off the flow.
The break occurred in the 2500-block of South Claremont Avenue, according to ABC7 Chicago. Firefighters were initially dispatched for a water leak inside a single home, but crews quickly discovered the real source was a broken water main outside, which sent water into basements along the block.
Once crews realized the scope of the damage, firefighters went house to house and evacuated people from homes in the flood's path. The Water Department has since shut off the water, and fire crews remained on scene afterward, checking homes along the block. No injuries have been reported.
Resident Describes Watching Her Home Fill With Water
For homeowner Tracy Cadenas, the flooding wiped out what was on her basement floor in a matter of moments. “Everything is ruined. Everything that was on the floor, the shoes, it is all the way to my knees,” she told the outlet.
The exact cause of the Claremont Avenue break, along with the age or size of the pipe involved, has not been established. It's also not yet clear how many residents were displaced, where they went, or when they'll be able to return to their homes.
Part of a Broader Pattern of Aging Pipes
In August 2025, CBS News Chicago reported water main breaks in Norwood Park Township, Addison, Schaumburg and Lockport. Roughly half of the water mains across the region are more than 50 years old, and some are over a century old, the station reports, while shifting ground caused by temperature swings and nearby construction work can both put stress on aging underground pipes.
Similar breaks have caused disruption well beyond Chicago. In February 2025, a 54-inch water main built in the 1930s burst in southwest Detroit, forcing dozens of residents from their homes and prompting one hospitalization for a breathing issue, according to Bridge Michigan. That state has wrestled with aging water and storm-drainage systems for years; a 2016 state commission recommended Michigan spend $1 billion annually to address the problem.
Closer to home, a break in suburban Dixmoor impacted more than half of that village's residents and businesses, per NBC Chicago, with officials unable to offer a timetable for repairs. And in Southern California this month, a 6-inch water main broke overnight near Sherman Oaks, flooding a street and affecting 23 water services before crews restored service the following afternoon, KTLA reported.
What Options Exist for Affected Homeowners
Residents whose property is damaged by flooding tied to city infrastructure or construction can pursue a claim through the City Clerk's Claims process, according to guidance posted by the City of Chicago. It has not been established whether the Claremont Avenue break was caused by city infrastructure or construction. The city's Department of Law processes property-damage and personal-injury claims through its Claims Unit, though it does not handle workers' compensation claims or disputes over water bills.
It remains unclear whether the city will reimburse the affected Heart of Chicago homeowners or whether any insurance claims have been filed in connection with Wednesday's flooding. For now, residents along Claremont Avenue are left assessing the damage while repair crews continue their work.
