Legionella Bacteria Detected in Aylesford Water System
Routine Checks Highlight Importance of Control Schemes
Following routine water system monitoring, Legionella bacteria were identified within the water system at a veterans’ facility in Aylesford. While Legionella bacteria occur naturally in water, they can multiply in man-made systems if conditions allow, particularly where temperature control and maintenance are inadequate. Inhaling contaminated water droplets can lead to Legionnaires’ disease, a potentially serious respiratory illness.
Routine Monitoring Enables Early Intervention
Crucially, the detection was made through planned monitoring activities, demonstrating the value of a proactive approach to water hygiene management. Identifying elevated results early allows dutyholders to respond promptly, reducing the likelihood of exposure and preventing risks from escalating.
Routine monitoring supports best practice in line with the Health and Safety Executive’s Approved Code of Practice (ACOP) L8 and the associated technical guidance HSG274, both of which emphasise the importance of ongoing surveillance.
The Role of a Written Control Scheme
ACOP L8 requires dutyholders to implement and maintain a written control scheme for water systems. This scheme should clearly define how Legionella risks are managed and reviewed.
An effective control scheme typically includes:
- Regular inspection of water systems
- Temperature monitoring and flushing regimes
- Routine sampling where appropriate
- Clear procedures for responding to elevated results
These measures help ensure control strategies remain effective and that any deterioration in system performance is identified quickly.
Managing Risk and Demonstrating Compliance
Early detection and timely action not only protect building occupants but also demonstrate good practice and regulatory compliance. Without a robust control scheme, Legionella risks may go unnoticed, increasing the potential for harm and leading to more disruptive and costly remedial works.
