Legionella risks rise with warmer weather: essential guidance for facilities managers
As temperatures climb during the summer months, the risk of Legionella bacteria proliferating in water systems increases significantly. Recent warnings highlight the need for heightened vigilance and proactive management to prevent potential outbreaks of Legionnaires’ disease.
Understanding the impact of warmer weather on Legionella growth
Legionella bacteria thrive in water temperatures between 20°C and 45°C. During warmer periods, water systems can inadvertently reach these optimal growth conditions, especially in:
- Outdoor water features: Fountains, decorative ponds, and cooling towers exposed to direct sunlight.
- Air conditioning units: Systems that may accumulate condensation, providing a breeding ground for bacteria.
- Stored water systems: Tanks and pipes where water may become stagnant and warm.
The importance of proactive Legionella management
To mitigate the heightened risk during warmer weather, facilities managers should implement the following measures:
- Regular temperature monitoring: Ensure that hot water is stored above 60°C and cold water below 20°C to inhibit bacterial growth.
- System flushing: Regularly flush seldom-used outlets to prevent water stagnation.
- Routine maintenance: Descale and disinfect showerheads, taps, and other water outlets to remove potential biofilms.
- Risk assessments: Conduct comprehensive evaluations of all water systems to identify and address potential hazards.
