    NCH has been working to bring awareness of Legionella and the potential deadly effects to customers across Asia, as well as other parts of the world. Awareness of this disease has grown in recent years. Each major outbreak is associated with illness and fatalities. It is now even more important that organizations and individuals understand their legal duties and the consequences of failure to comply with legislations. 

    Under certain environmental conditions, any water system could become a source for Legionella bacteria.

    Legionella bacteria are common in lakes, ponds and rivers; however outbreaks of Legionnaires’ disease rarely originate from these sources. Outbreaks of the illness occur from exposure to Legionella growing in purpose-built systems such as: cooling towers, hot and cold water systems and spa pools. Water in these systems is maintained at a temperature high enough to encourage growth. Humidifiers, air washers, emergency showers and ornamental fountains also pose a risk for Legionella bacteria growth.

    If your system has a water temperature between 20-45°C, stores/re-circulates water, is likely to contain a source of nutrients (sludge, scale or fouling) or spreads breathable droplets e.g. aerosol created by a cooling tower or water outlets then your system is at risk for Legionella.
