How JLL Saved 600 Liters of Water Per Tap Annually Through Legionella Compliance

In every building with a water system, pipes need to be actively monitored to reduce waterborne pathogen risks (like Legionella and Pseudomona Aeruginosa). Managers need to ensure water services operate at temperatures that do not encourage pathogen growth and water is not left stagnant.

Infogrid’s pipe monitoring solution couples Disruptive Technologies’ sensors with proprietary algorithms which provide data on water temperature and which taps, if any, still require flushing for compliance.

It automatically generates required reports and provides a data trail for when manual flushing was undertaken. Deployment is quick and simple: For a building with 18 bathrooms, it took two hours to install.

Improve your environmental footprint and gain early indication of water system issues

Engineers now only need to visit the site once a year rather than 12 times, saving fuel. Taps no longer need to be manually flushed saving water and the energy required to heat it. And the system provides information every 5 minutes, so alerts can be set to ensure flushing more often than the required for compliance, improving overall safety.

Frequent readings also mean that issues such as deteriorating performance of calorifiers, can be identified and corrected before they become a bigger issue.

The sensor solution helped save 2900 kg of carbon across the building and 600 liters of water per tap annually.


Reduce the time required for legionella compliance.

Legionella compliance is largely a monthly process (often in settings like acute hospital wards). It involves running every tap for 2-5 minutes and manually measuring the temperature. This is time-
consuming and wasteful of both the water and the energy to heat it.

The Infogrid Pipe Monitoring solution provides information  on water temperature and which taps, if any, still required flushing for compliance.

With the system in place, an engineer is no longer required to drive to the site every month to manually flush every tap and check the temperature, and can instead be deployed on more value-added tasks. Staff only have to periodically run the few taps which are not flushed during normal usage. This saves 81% of the time spent.


The Infogrid pipe monitoring solution fully automated our legionella reporting, allowing us to reduce the time spent on legionella compliance by 81%.

How The Sensor-Based Legionella Compliant System Works

Place two Disruptive Technologies sensors in the sentinel and calorifier, cable-tied to the pipes using pipe brackets. For a fuller picture, add sensors to the Cold Water Storage and the Thermal Mixing Valves.

Sensor in location

Plug in the cloud connectors. The entire installation process is fast and easy: 20 bathrooms can be installed in 2 hours.

Set up alerts in the Infogrid software - for example, if a particular tap has not been flushed for a week, or if the temperature is outside of the permitted areas - and for the action taken to be recorded.

Adjust permissions for using the system to your liking - either overall or for specific groups of sensors. View live and historic data and automate the generation of reports required for compliance.


Why Disruptive Technologies Sensors

Sensors used to be bulky, complex and often inaccurate. We've completely rethought sensor design to enable data collection anywhere and everywhere. There's no need to "rip and replace" legacy systems to turn them into "smart" equipment.

  • Mini-sensors are the size of a postage stamp
  • Low power consumption means long battery life
  • Robust construction
  • Cost-efficient
  • Direct connections provide maximum accuracy
  • Industrial-grade connectivity and built-in redundancy
  • Supports next-generation Internet of Things (IoT) networks
  • End-to-end security built into the design
  • Extensible platform to integrate into your systems
