What is Legionella?

Legionella bacteria can cause Legionnaires’ disease, a potentially serious form of pneumonia. The bacteria are commonly found in man-made water systems, including hot and cold water systems, cooling towers, calorifiers and spa pools. Legionella thrives in stagnant water and temperatures between 20°C and 45°C, particularly where systems are poorly maintained or inadequately controlled.

Effective Legionella management and control is vital to prevent bacterial growth, reduce exposure risk and protect building occupants, staff and visitors.
