Early Water Leak Detection for Facilities Managers

Detect even the smallest of leaks in the least accessible places, before they cause major maintenance issues.

Meet Severn WLD™: Facilities Managers' predictive water leak detection solution

Escape of water leaks in UK commercial & residential buildings cost £987M in 2022. Manual water leak inspections are no longer enough. You need predictive water leak detection.

Severn WLD™ is a smart water leak detection system that tells you where a leak is before you can even see it. Using smart technologies, it precisely detects and locates leaks for you well before they cause a significant problem.

Don’t let small, virtually undetectable leaks turn into an expensive repair job. Detect and repair them before they cause a major issue.

How Facilities Managers benefit from early water leak detection

Streamline maintenance operations

Minimize resource-intensive manual water leak inspections, especially in large sites and hard-to-reach places. Redirect resources from leak detection to repair and maintenance.

Achieve greater operational efficiency

Spend less time and money on manual water leak detection - and even less on major repairs and facility downtime due to catastrophic leaks.

Drive informed decision-making

Get access tro proprietary data. Gain insights into where and when leaks occur. Identify factors that increase the likelihood of leaks, across facility layouts, usage and parts.

Enhance sustainability performance

Significantly reduce water loss derived from detected leaks, enhancing your facilities’ sustainability.

Where Facilities Managers use Severn WLD

Facilities managers can use Severn WLD to monitor anywhere a leak is likely, costly, or both - including:

  • On pipes, flanges and fittings.
  • Near dishwashers.
  • Near pumps and condensate drains.
  • In shower trays and under baths.
  • Under sinks and toilets.
  • In utility cupboards.

Everything Facilities Managers need to know about IoT communication protocols

(but don't want to ask)

Our Quick Reference Guide breaks down the pros and cons of 6 of the top IoT protocols for wireless water leak detection, in clear language.

No technical guff, just straightforward explanations designed to help you choose which protocol is right for the facilities you manage.

Wireless Smart Water Leak Detection Comms Protocols


How does Severn WLD work?

The Severn WLD device checks for water on each of its electrode every minute. When it detects the presence of water on 4 or more electrodes, the device uses the LoRaWAN communication protocol to send an emergency message to a gateway, which then connects with LAIIER Cloud and notifies you via email or SMS.

(You have the option to change the level of sensitivity for water detection, triggering an alert when just one electrode detects water, or any number up to the full 12 electrodes.)

To give you peace of mind that Severn WLD continues to operate even when there's no water detected, it also sends a regular "heartbeat" message to LAIIER Cloud every 4 hours. 

Can I change the settings on the Severn WLD?

Yes, you can change some of the settings on Severn WLD:

  • The threshold.
  • The number of electrode segments that have to be wet to trigger an emergency message.
  • The regular "heartbeat" message time interval.

How often does the Severn WLD check for water or send a message?

The Severn WLD device checks for water every minute, and sends an emergency message immediately when water is detected.

Severn WLD sends a regular “heartbeat” message every 4 hours. 

How long does the battery last?

The active battery life is 3-4 years.

However, the battery life may vary, depending on:

  • The frequency of the regular "heartbeat" messages.
  • The distance from the LoRaWAN gateway.
  • The temperature.
