6.4 Recommendations for prevention of Legionella growth (based on European standard CEN/TR 16355)
Informative
Legionella are small rod shaped bacteria which are a natural constituent of all fresh waters.
Legionaries’ disease is a serious pneumonia infection caused by inhaling the bacteria Legionella pneumophilia or other
Legionella species. This bacterium is frequently found in domestic, hotel and other water systems and in water used for
air conditioning or air cooling system. Hence the main intervention against the condition is prevention, through control
of the organism in water systems.
The European standard CEN/TR 16355 gives recommendations for good practice concerning the prevention of
Legionella growth in drinking water installations but existing national regulations remain in force.
General recommendations
"Conditions for Legionella growth". The following conditions encourage Legionella growth:
 water temperature between 25 °C and 50 °C. To restrict the growth of Legionella bacteria, the water temperature
shall be in a range that the bacteria will not grow or have minimum growth, wherever possible. Otherwise, it is
necessary to disinfect a drinking water installation by means of a thermal treatment;

stagnation of the water. To avoid long periods of stagnation, the water in every part of the drinking water installation
should be used or flushed at least weekly;
