Legionella bacteria live in water and can cause legionnaires' disease. According to a study conducted by the Robert Koch Institute (German only), the disease causes about as many deaths in Germany as are caused by traffic accidents (German only).
Infection happens through the inhalation of droplets in the shower, for example. Pseudomonas and other germs also create sources of danger.
It is true that drinking water is never completely germ-free, but normally the concentration of germs is harmless. Health risks only arise when the germs are able to multiply. Stagnant water and water temperatures between 25 °C and 50 °C can encourage bacterial growth. In practice, the risk is likely to occur in empty properties, in rooms that are only used intermittently or in cases where dead-end pipes are not in use.
Hygiene problems caused by excessive proliferation of germs can be reliably avoided through:
Biofilms form anywhere that water circulates, including drinking water systems. Normally, they don’t pose any problems and don’t affect the quality of drinking water. Health risks only arise when the germs are able to multiply. Stagnant water and water temperatures between 25 °C and 50 °C can encourage bacterial growth. In practice, the risk is likely to occur in empty properties, in rooms that are only used intermittently as well as in dead-end pipes. Hygiene problems caused by excessive proliferation of germs can be reliably avoided through:
Anyone inhaling legionella can be infected. This can happen anywhere that polluted water droplets enter the air as aerosols; for instance, under the shower or on taps.
Legionnaires’ disease can trigger pneumonia. However, it is often not identified as the cause of illness. For that reason, the estimated number of unreported cases is high and the significance of the disease is underestimated. The same is true of pseudomonas, which can trigger gangrene and develop resistance to antibiotics.
When you encounter serious hygiene issues resulting from stagnant drinking water, you need rapid action. With the new Geberit sanitary flush Rapid, the problem can be resolved quickly and easily. It is easy to use and provides all basic functions for regular water replacement. This compact and economical hygiene solution is battery-operated and can be put into action immediately, in exactly those areas that are at risk of stagnation. This makes it an ideal interim solution if, for example, major renovation measures cannot be implemented immediately.
Guaranteeing drinking water quality in domestic installations is the subject of various ordinances and standards. At a European level, Directive 98/83/EC governs the quality of water for human consumption. Sanitary engineers, plumbers and operators are safe from a legal perspective if they observe directives like this and comply with country-specific regulations.
