What is legionella?

Legionella is a bacterium that can be found in sources like surface water or water distribution systems. Under favorable conditions, Legionella proliferates rapidly. Temperatures ranging from 25 to 45 degrees Celsius create an ideal environment for Legionella bacteria to multiply rapidly. Beyond 60 degrees Celsius, Legionella bacteria begin to perish.

The Legionella bacterium strives to establish itself within the biofilm—a slimy layer—found inside pipelines or in sediment at the base of reservoirs. This biofilm contains elements that serve as nutrients for the bacteria. Adequate water flow is crucial because stagnant water in certain areas prevents renewal and fails to reach high temperatures. Merely consuming this water can have adverse effects. However, the potential dangers escalate significantly when inhaling aerosols. Inhalation of these aerosols can lead to contamination by the Legionella bacterium, carrying significant risks and potential hazards.

Recognise legionella

Recognizing Legionella isn’t straightforward. Not everyone exhibits symptoms after exposure to the bacterium. However, if symptoms do occur, they may include:

  • Rapid onset of fever
  • Muscle pain
  • Dry cough
  • Shortness of breath
  • Headache
  • In some cases, the Legionella bacterium can cause severe pneumonia.

Testing for Legionella can be done through a rapid test conducted by a doctor. Various tests are available for personal or organizational use. Such a rapid test can determine if the bacterium is still present in drinking water, pool water, or tap water.


Prevent legionella

To prevent closure of your organization due to a Legionella outbreak, consider applying our showerheads, faucets, and filters. These provide protection against Legionella outbreaks. You can easily install the membrane filters yourself, requiring cartridge replacement every three months.

Other tips to prevent Legionella include:

  • Run all hot and cold water taps every week.
  • If taps haven’t been used for a week or longer, let both hot and cold water taps run for five minutes.
  • Ensure thorough flushing of showers.
  • If absent for an extended period, flush the pipes with hot and cold water.
  • Maintain the water temperature in your central heating boiler, solar heater, or other hot water sources at a minimum of sixty degrees Celsius.
