Water leak protection in construction

Water is the biggest risk on an active build

Water is the quiet saboteur of construction. Industry analysis puts water events at nearly 60 percent of real-estate claim frequency and more than a third of total loss dollars. Burst risers, failed fittings and unmonitored temporary lines can halt a schedule overnight, and the bill lands on the contractor and the owner at the worst possible moment.

The hard part is timing. Most of these failures happen after hours, on a floor that is finished enough to flood but empty of anyone who would notice. A line lets go at 2am and runs until the first crew arrives. By then the drywall, the millwork and the schedule have all taken the hit.

Where water goes wrong on a jobsite

Three patterns account for most construction water loss, and all three are about the building's own systems, not the weather.

Hidden after-hours leaks. A concealed line fails in an empty building and runs for hours across multiple floors. Wireless sensors catch the change in flow or the presence of water the moment it starts, and the affected riser or zone shuts off automatically within seconds. An overnight disaster becomes a minor cleanup.

Pressure spikes and frozen lines. When a pipe bursts, crews are pushed off site and the critical path stops. Continuous condition monitoring flags abnormal pressure or temperature early, so the team can reinforce or repair a vulnerable section before it fails.

Untracked water use. Even without a failure, wasted water quietly erodes the budget and undermines ESG and LEED targets. Real-time flow analytics show exactly where and when water is being used, so managers can cut consumption and stay on target.

Five layers of protection for a construction site

A complete program covers the site from the water main down to a single temporary hose.

• Water-main protection. Remote or automatic shutoff for the entire site, containing a major break instantly.
• Domestic-zone protection. Isolates individual floors or risers, so work continues elsewhere while a repair is made.
• Temporary-line protection. Guards above-ground hoses and provisional piping during the build. Sensors and valves shut water off the moment a line fails or a fitting pops.
• Common and mechanical-area sensors. Cover pump rooms, elevator pits and mechanical penthouses, the high-risk zones no one is watching at night.
• Cloud dashboard and 24/7 monitoring center. Live alerts and round-the-clock support, so no warning goes unnoticed.

Together these turn water from a looming threat into a managed variable.

Proof on real projects

Eddy has run this model on active sites for years, including a multi-year program with PCL Construction that has protected dozens of marquee projects across North America from excavation through fit-out.

The pattern shows up again and again in the field. A concealed bathroom leak shut off the same second it was detected on a floor still being built. A laundry-connection leak at 4am on an empty site was contained before it cost a single day. On monitored sites the numbers hold: response in under two minutes from alert to action, an estimated $50,000 to $250,000 in avoided cost per incident, and no schedule slippage tied to water.

From construction through to operations

The most expensive water events happen at the handoff, when the temporary protection comes out and the operational system is not yet live. The same Eddy network that guards the build can carry forward into occupancy, so there is no gap and no second procurement. We cover that handoff in detail in the construction-to-operations gap.

Frequently asked questions

Does Eddy work during active construction, before occupancy? Yes. Course-of-construction protection is designed for open piping, parallel trades and an empty building after hours. Sensors and automatic shutoff are live from temporary risers through commissioning.

What about temporary hoses and provisional lines? Those are among the most failure-prone parts of a site. Temporary-line protection puts sensors and valves on above-ground hoses and provisional piping, and shuts water off the moment a line fails.

Does the protection carry into operations? Yes. The same hardware and monitoring that protect the build stay live through occupancy, so the operating-building program does not start from scratch.
