Why industry leaders & innovators trust LAIIER

Our clients—including global manufacturers and property operators—choose LAIIER for reliable, scalable, and easy-to-deploy water sensors. With real-time notifications, our system prevents costly water damage caused by undetected leaks.

The speed of the alerts we’ve had so far was very impressive, and gives me great confidence that we’ll be able to deal with any future water leaks well before they become a disaster.

We believe that sensors for remote monitoring, such as the LAIIER leak detection sensor, represent an important preventative measure towards potential unforeseen damage.


Water leak detection purpose-built for commercial and industrial use

Severn WLD is a smart leak detector designed to monitor plumbing fixtures, pipes, HVAC systems, laundry rooms, basements, and water heaters. Unlike consumer devices, our solution is engineered for enterprise-scale deployment.

  • Detecting leaks early prevents downtime and costly repairs.
  • Easy setup with standalone, wireless operation.
  • Compatible with existing building management systems (BMS).

Severn WLD is currently deployed in a range of settings, including multifamily residential, office, life sciences, and hospitality buildings in North America and Europe.

Accurately and precisely detect water leaks - before significant damage occurs

Severn WLD detects water leaks when they start - when leaks are small, and damage is minimal.

When you receive a leak alert, you'll know exactly where the water is pooling: not just which floor or room, but which specific portion of a single device has detected the leak.

  • Avoid small leaks becoming catastrophic.

  • Decrease response times by providing precise leak location information.

  • Minimize avoidable damage and associated repair costs.

Make better, data-driven decisions

Severn WLD helps facilities managers track performance across multiple sites. Real-time alerts can be sent directly to your phone and web  app, enabling property and facilities managers to respond instantly.

  • Assess the growth of small leaks and prioritize their repair against other tasks.

  • Discover common water leak sources and create a proactive maintenance plan to replace at-risk fixtures or appliances.

  • Use the data to demonstrate the effectiveness and ROI of your water leak detection investment, request budget, or support ESG and sustainability.

  • Integrate with your existing BMS or other software systems on request.

Minimize maintenance 

Our thin, flexible sensor is designed to fit discreetly under plumbing fixtures, dishwashers, sinks, and water tanks and more. With simple plug-and-play installation, you can deploy at scale without disruption.

  • Review and manage device status and data in our cloud dashboard.

  • Robust IP65-rated enclosure ensures continuous detection, even in industrial environments.

  • Save time on maintenance with a 6-year battery life.

  • Sensor dries on its own, or can be wiped dry to reset.

Make installation & retrofitting easy

Severn WLD makes installation quick and easy, with no specialist tools or training required, even if it's being retrofitted.

  • Trim the flexible sensor strip down to size for use in smaller spaces.

  • Install without worrying about needing access to electrical outlets: Severn WLD is wireless and battery-powered.

  • Take just minutes to install each device, without needing to undergo lengthy training courses or buy specialist tools.

Integrate with existing infrastructure, or operate as a standalone solution

Have an existing LoRaWAN® network? We can connect your Severn WLD devices to it.

No network? No problem - we'll provide the gateways to get you started.

Our water leak detection solution includes our cloud-based dashboard and device management by default.

Want to push the data to a BMS or other software solution? Integrations are available on request.

Avoid water damage from periodic events or periods of inactivity

Unmonitored spaces such as basements, laundry rooms, and bathrooms are common sources of leaks. Severn WLD prevents unexpected floods and ensures your property remains protected at all times.

  • Mount the water leak sensor vertically to measure ground water ingress

  • Set specific thresholds to alert when water levels are above a specified limit

  • The Severn WLD easily conforms to existing infrastructure

Prevent Water Damage Before It Happens

Water intrusion can destroy valuable property, equipment, and tenant spaces. Our system is engineered to prevent water damage before it spreads, saving both time and money.

 

Customize your water leak alert settings

Manage your water leak alert settings in our cloud dashboard: who gets them; and whether it's via SMS, email, or both.

It's also where you manage water leak alert thresholds for your devices, to better serve a broad range of use cases with varying leak tolerances.  For example:

  • In an environment where any water is a problem, like a data center or climate-controlled area, get alerts for water leaks as small as a single drop of water.

  • In an environment where false positives from condensation or cleaning are more likely, like in plant rooms, or under commercial appliances, set alerts for medium-sized water leaks.

How it works

Diagram of LAIIER's water leak detection solution

  1.  Install sensors in high-risk areas (pipes, HVAC units, water heaters, etc.).

  2. The sensor tracks leaks, temperature, battery life, and whether the sensor has been moved.

  3. When a leak is detected, battery-powered Severn WLD devices send an instantaneous message to a local gateway via the secure LoRaWAN protocol.

  4. You receive SMS, email, and LAIIER Cloud dashboard alerts instantly.

Water leak detection use cases

Severn WLD detects water leaks inside commercial and industrial buildings, including in and around appliances and industrial equipment. Popular use cases include:

Frequently asked questions

Will Severn WLD reduce false positives?

Severn WLD has a very low false positive rate.

While its high sensitivity enables the detection of very small amounts of water, the customizable leak alerts mean that you won't receive information about leaks that you consider so small that you'd call them a false positive.

Unlike many water leak detection rope sensors, Severn WLD isn't affected by dust; and because it quickly wipes dry after a leak, it doesn't continue to send false positive alerts due to slow drying times.

Can I customize my water leak alerts?

Yes, you can customize your water leak alerts:

  • Choose what you consider a big enough leak to justify an alert.
  • Choose who gets the alerts.
  • Choose whether the alerts are sent by SMS, email, or both.

Which communication protocols do you use?

Severn WLD transmits data via LoRaWAN, a globally recognized wireless communication protocol designed to connect battery operated devices to the internet in regional, national, and/ or global networks.

LoRaWAN is secure, requires minimal power, transmits small packets of data across long distances, and is an open protocol that's vendor agnostic.
