State of Water Management 2026
Water is the most expensive peril hiding in plain sight. It costs more than fire. It costs more than theft. And yet, in most commercial buildings, the primary detection method is still a human being noticing a wet floor — or opening a water bill 30 to 90 days after the problem began.
The 2026 State of Water Management is the largest analysis of real-world water events in commercial buildings we've ever released. The report draws on more than 480,000 alerts recorded by the AlertAQ™ water intelligence platform across 14,000+ buildings in the United States and Canada during a single calendar year.
The data spans three categories of water risk: physical water presence (flood detection), abnormal water consumption (flow intelligence), and environmental conditions that threaten building integrity (temperature and humidity monitoring). Whether you manage buildings, insure them, or invest in them, this report shows where water problems start, how fast they're caught, and what happens when no one is watching.
Here are three of the most significant findings.
1 in 4 monitored buildings experienced a flood event
More than 30,000 flood alerts were recorded across thousands of buildings in 2025 — roughly one in four buildings with Alert Labs leak detection installed experienced at least one flood event during the year.
Bathrooms account for more than one in three of all detected floods. Mechanical rooms are second at 26%. Together, these two zones represent over 60% of all flood events detected. For facility managers planning sensor deployments, these are the rooms to prioritize — but the long tail of kitchens, laundry rooms, and electrical rooms matters too.
56% of flood events happen after hours
When you define "after-hours" as weekday evenings, overnights, and all of Saturday and Sunday, more than half of all flood events occur when most buildings have reduced or no staff on site.
The median flood alert was resolved in 57 minutes — but that 57 minutes reflects how quickly building staff responded, not how quickly the sensor detected the water. The sensor detects instantly. Without automated detection, a flood that starts at 6 PM on a Friday could run undetected until 8 AM Monday — 62 hours of unchecked water damage.
Why this matters: For buildings relying on manual walkthroughs or scheduled inspections, the majority of water events start when no one is there to notice them.
3.4 billion gallons of water waste flagged — $28 to $41 million in potential costs
More than 90,000 leak and abnormal high water use alerts were recorded across nearly 4,500 buildings. Continuous leaks — stuck toilet flappers, running supply lines, failed valves — account for 94% of all water volume detected, despite representing fewer than half of total alerts.
The quiet, persistent leak is the one that drives up your water bill. The EPA estimates that a single running toilet can waste 200 gallons per day. NYC's Department of Environmental Protection puts the figure higher: a continuously running toilet can waste up to 6,000 gallons daily. Without real-time flow monitoring, these leaks persist until the utility bill arrives — typically 30 to 90 days later.
Why this matters: Water waste is not just a billing problem. A leak that runs long enough becomes a damage event. AlertAQ™ catches these events while they're still a utility problem, before they become a restoration project.
