Keep Your Customers And Workforce Safe By Testing For Legionella Bacteria

Did you know if the Water in your Storage Tank has been sitting idle for more than 14 days that you may be at risk of it being infected with Legionella? If this is the case is vitally important that you have your Water Storage Tank cleaned.  

What is Legionella?

Legionella bacteria is commonly found in water. The bacteria multiply where temperatures are between 20-45°C and nutrients are available. The bacteria are dormant below 20°C and do not survive above 60°C.

Legionnaires’ disease is a potentially fatal type of pneumonia, contracted by inhaling airborne water droplets containing viable Legionella bacteria. Such droplets can be created, for example, by hot and cold water outlets; atomisers; wet air conditioning plant; and whirlpool or hydrotherapy baths.

Anyone can develop Legionnaires’ disease, but the elderly, smokers, alcoholics and those with cancer, diabetes or chronic respiratory or kidney disease are at more risk

There are no vaccines to protect against Legionaires’ disease.  Instead the key to prevention is to make sure that building owners and managers maintain building water systems in order to reduce the risk of Legionella growth and spread. Examples of building water systems that might grow and spread Legionella include:

  • Hot tubs
  • Hot water tanks and heaters
  • Large plumbing systems
  • Cooling towers (structures that contain water and a fan as part of centralized air cooling systems for building or industrial processes)
  • Decorative fountains



In order to control the Legionella risk and maintain water hygiene, water storage tanks should be inspected regularly as part of your monitoring program that was formed in line with your risk assessment and, if necessary, physically cleaned and then disinfected.
