Legionella Monitoring

The ADM GeneSys Web Wireless Monitoring System is versatile and can be configured for many tasks, including reducing the risk from Legionella.

Effective Legionella monitoring is essential for protecting building occupants and helping organisations comply with their legal responsibilities for water hygiene management. At ADMWISE, we provide intelligent wireless monitoring solutions that enable businesses to continuously monitor the temperatures of hot and cold water systems, reducing the need for manual checks while providing accurate, reliable data around the clock.

Legionella bacteria multiply where water temperatures are between 20°C and 45°C and nutrients are available. Below 20°C the bacteria becomes dormant, while temperatures above 60°C prevent its survival. As a result, maintaining and monitoring water temperatures is recognised as the primary method of controlling the risk of Legionella within domestic and commercial water systems. Continuous temperature monitoring provides early warning of any deviations, allowing corrective action to be taken before conditions become favourable for bacterial growth.

Our wireless sensors continuously monitor water temperatures at critical points throughout your water system, including calorifiers, hot and cold water storage tanks, sentinel outlets, return loops and other key monitoring locations. Data is automatically transmitted to the ADMWISE WISE Platform, where facilities managers can view live readings, historical trends, automated reports and alarm notifications from any internet-connected device. If temperatures move outside predefined limits, instant alerts are sent via email, SMS or telephone, enabling maintenance teams to respond quickly and minimise potential risks.

Continuous monitoring helps organisations support compliance with the Health and Safety Executive’s Approved Code of Practice (ACOP L8) and HSG274 guidance by providing a secure digital record of water temperatures and system performance. Automated reporting removes the need for paper-based temperature logs, reduces administration time and creates a complete audit trail that can be accessed during inspections, audits and compliance reviews.

Our Legionella monitoring solutions are ideal for hospitals, care homes, schools, universities, hotels, leisure centres, commercial offices, industrial facilities and public buildings where water hygiene management is critical. The system can easily scale from a single building to a large multi-site estate, providing complete visibility of your water systems through one secure cloud-based platform.

With real-time monitoring, automated alerts and comprehensive reporting, ADMWISE helps organisations take a proactive approach to Legionella risk management. By identifying temperature issues early, reducing manual inspections and providing reliable compliance records, our wireless monitoring solutions help protect building occupants, improve operational efficiency and support effective water safety management.
