When Century-Old Water Mains Fail: The Hidden Threat Lurking Beneath Milwaukee County’s Streets

Milwaukee County homeowners face a growing crisis that most never see coming—until water starts gushing through their basement walls. The age range of Milwaukee’s water mains spans from 1873 to the present, meaning thousands of homes depend on pipes that have been buried underground for over 150 years. While new mains made of ductile iron pipe are designed to last over 100 years, the reality is that much of Milwaukee County’s infrastructure has far exceeded its intended lifespan.

The Scale of Milwaukee’s Infrastructure Challenge

Since 1993, Milwaukee Water Works has invested significantly in system improvements, including replacing aging water mains, maintaining over 2,000 miles of water pipes, and operating 20,000 hydrants across Milwaukee and neighboring communities. However, the sheer scope of the problem means that Milwaukee Water Works strives for a 100-year replacement cycle for water mains, while also being challenged to fund the replacement of over 70,000 lead service lines that serve the community.

The consequences of this aging infrastructure are becoming increasingly apparent. Mains are made of iron and are buried in soil which promotes corrosion. The corrosion weakens the structure of the pipes, which over time results in small holes and cracks appearing. As the water leaks through these holes and cracks, the pipe becomes even weaker and this can result in a burst water main.

How Water Main Breaks Devastate Homes

When these century-old pipes finally give way, the damage can be catastrophic. Recent incidents in Milwaukee County demonstrate the real-world impact on homeowners. A water main break in Greenfield left several residents near 37th and Kimberly facing thousands of dollars in damage and uncertainty about who will cover the costs. Harold and Sherryl Janas had a hard time sleeping after their basement flooded when a City of Milwaukee water main broke near their house.

The financial burden can be overwhelming. Harold Janas estimated “Almost $10,000, at least,” in damage, while another resident’s insurance company would only cover up to $10,000 worth of damage—just a fraction of what the total cost may be. Making matters worse, recent events have shown that claims for water main breaks are not often successful. In 2019, a water main break on Hawley Road just south of I-94 caused extensive flooding, but the City Attorney determined the city could not have known a pipe would fail before the break, and all claims were denied.

The Perfect Storm: Multiple Factors Increase Break Risk

Other causes of main breaks are ground movement (e.g., due to frost penetration), changes in water pressure, electrical corrosion, being struck during excavation by other underground utility work, pressure from heavy traffic or construction, and normal age deterioration. Winter freeze and thaw cycles cause an increase in broken water mains as the water in the soil under the pavement freezes and thaws, putting pressure on the main.

The pressure within these aging systems compounds the problem. Because water mains are under great pressure, even a small hole can allow large amounts of water to escape. This means that what starts as a minor crack can quickly become a major flood that sends thousands of gallons rushing into nearby homes.

Beyond Main Breaks: The Broader Water Damage Risk

Milwaukee County’s water challenges extend beyond just main breaks. The region’s aging infrastructure contributes to various flooding scenarios that can damage homes. Sometimes, the city’s system can’t handle the amount of rain we get, and water backs up into your basement. Even a sump pump won’t save you in that case.

Recent extreme weather events have highlighted these vulnerabilities. According to the Wauwatosa Police Department, over 500 calls were received by their dispatch center with issues ranging from flooded out basements to blocked storm drains to traffic incidents due to standing water.

The Investment Challenge

Addressing Milwaukee County’s aging water infrastructure requires massive investment. The cost to replace one mile of water main is approximately $1.3 million. Fifteen miles of main were completed each year in 2015, 2016 and 2017. Eighteen miles of main were replaced in 2018 and planned for 2019.

While investing in water main replacement is paying off, with a downward trend in the number of main breaks each year since the 1970s, the pace of replacement still lags behind the rate of deterioration for the oldest sections of the system.

Protecting Your Home

Milwaukee County homeowners should understand that the region faces unique water challenges, from spring storms that overwhelm century-old sewer systems to sump pumps that fail during the worst possible moments. Being prepared with emergency contacts for professional restoration services and understanding your insurance coverage can make the difference between a manageable incident and a financial disaster.

The reality is that Milwaukee County’s 100-year-old water mains will continue to fail, and homeowners need to be prepared for the potential consequences. With proper professional response and restoration services, however, the impact of these infrastructure failures can be minimized, helping families recover and get back to normal life as quickly as possible.
