Legionnaires, a fatal disease, spreads if water temperatures are too high or too low. Monitoring this is labour intensive. A London hospital wanted to optimise assets and save cost, but they had many staffers, who were testing over 9,000 taps on an ongoing basis to reduce the spread of Legionnaires disease.
Temperature sensors were fixed to taps. The sensors fed information to a dashboard which then sends alerts to the facilities team if the tap becomes too hot or too cold.
Staff were only dispatched to monitor the taps when an alert was received on the dashboard. This saved time and money and enabled fewer people to be more responsive.
