Legionella Services
Legionella is the bacteria responsible for legionnaires disease, an uncommon but potentially fatal lung infection. Legionnaires disease is contracted through exposure to and inhalation of tiny water droplets and vapour from water systems containing high levels of the legionella bacteria. The bacteria thrives in warm and hot water, however, in warmer climates, even cold water systems may reach temperatures sufficient for legionella to grow.

Legionella – Frequently Asked Questions
What is Legionella?
Legionella is a type of bacteria that is found naturally in freshwater environments such as lakes and streams. However, if it grows in human-made water systems like showerheads and sink faucets, it can become a health concern and lead to disease.
What causes Legionella in water?
Legionella can grow in your water systems when there is a reduction in disinfectant levels. Stagnant water is an ideal place for Legionella to grow, and because of this water outlets such as showerheads and taps can be a breeding ground for this sort of bacteria.
How serious is Legionella?
If droplets of water that are infected with legionella are inhaled, they can cause a lung infection known as ‘Legionnaires’ disease.’ This is quite uncommon, but in circumstances where this has occurred, it has been severe, and it some cases, fatal.
How often should water be tested for Legionella?
How often you test for Legionella can depend on the water system. For example, open water systems, such as cooling towers, evaporative condensers and spa pools, should be routinely tested at least quarterly. However, for both hot and cold closed water systems, regular testing is not required unless there are some doubts about the system.
How can Legionella be prevented?
To reduce the risk of Legionella in your water systems, you should make sure that any outlets that are not used regularly are flushed out once a week. Furthermore, it is important to clean and de-scale all showerheads and similar outlets at least once every few months to prevent a build-up of bacteria.
