Cook County’s Water Main Break Crisis: When Aging Infrastructure Turns Your Basement into a Swimming Pool
Cook County residents are facing an unprecedented challenge in 2025 as aging municipal water infrastructure reaches its breaking point, literally flooding basements across the region. In the Chicago area, 50% of the water mains are over 50 years old — and some are over 100, creating a perfect storm for homeowners dealing with unexpected water damage and costly repairs.
The Scale of the Problem
The statistics paint a sobering picture of America’s water infrastructure crisis. The American Society of Civil Engineers estimates that there’s a water main break every two minutes, with over 240,000 water main breaks occurring annually nationwide. Cook County is no exception to this epidemic, with recent incidents highlighting the vulnerability of local communities.
In February 2025, Skokie residents experienced firsthand the devastating impact of water main failures. The huge mess has also left some homes with flooded basements and potentially dangerous conditions for people who live nearby. One resident described waking up to “water pouring in through one of their basement windows” after living in their home for 50 years without experiencing such flooding.
Why Cook County is Particularly Vulnerable
Several factors contribute to Cook County’s water main break epidemic. From poorly executed construction to extremely cold temperatures, shifting earth, and aging infrastructure, water main breaks have many causes. The region’s infrastructure challenges are compounded by climate change, as our climate changes and storms grow more intense, that infrastructure is under new strain.
The director told NBC Chicago an overhaul of the aging infrastructure would cost billions of dollars, highlighting the massive financial challenge facing municipalities. Meanwhile, Cast iron pipes, prevalent in older systems, have an average lifespan of 75-100 years, meaning many have already reached or exceeded their operational limits.
The Basement Flooding Connection
Water main breaks don’t just affect street-level infrastructure—they directly impact homeowners through basement flooding. Factors contributing to frequent basement flooding in Chicago include the city’s old drainage systems, impervious surfaces like streets and parking lots, and overwhelmed sewer lines. When water mains fail, the resulting pressure changes and system overloads can push water into residential basements through connected drainage systems.
The summer of 2025 saw particularly severe flooding events, with more than 2,000 flooded basement reports were made on the Southwest Side and in the suburbs following intense storms. A storm on Friday afternoon brought 3 inches of rain to the Midway area, with some areas of Chicago getting up to 7 inches of water in 60-90 minutes.
What Homeowners Need to Know
Understanding the risks associated with aging water infrastructure is crucial for Cook County homeowners. Flooded basements pose several risks, including electrocution, black water contamination, extensive mold growth, and structural damage to foundations and building materials. When water main breaks occur, In many cases, you’ll find that the city government won’t pay for damage caused to your plumbing system by a water main break. This leaves you to shoulder the burden of repairs.
Prevention and preparedness are key. To prevent basement flooding, homeowners should inspect and repair foundations, ensure proper drainage, maintain sump pumps, disconnect downspouts from sewer systems, and consider landscaping adjustments.

Looking Ahead: Infrastructure Investment and Solutions
While the current situation is challenging, there are reasons for cautious optimism. Since launching in 2023, the Build Up Cook program has invested $11.5 million into drinking water projects, and The 2021 Bipartisan Infrastructure Law allocated $55 billion to water infrastructure improvements.
