Legionella are bacteria that live in the water and cause legionnaires' disease. This causes thousands of deaths every year – in Germany alone, there are as many deaths resulting from legionnaires' disease as from traffic accidents. Plumbers, sanitary engineers and building managers can significantly reduce this risk as you can only be infected by legionella if you breathe in infected water in the form of tiny droplets. This often occurs when taking a shower.
How do the germs end up in drinking water?
Drinking water is never completely germ-free. Nevertheless, the concentration of bacteria and germs is normally harmless. It is not until the germs are able to multiply that there is a serious risk. Multiplication of this type only occurs:
- in stagnant water and
- at temperatures of between 25 °C and 50 °C
If a drinking water installation is planned and designed properly, this can permanently prevent legionella and other germs such as pseudomonas from finding favourable living conditions.
Geberit solutions for protecting drinking water
Sanitary flush prevents germs from multiplying
The Geberit sanitary flush ensures reliable water replacement in drinking water installations. This means that excessive stagnation times or unfavourable temperatures can be avoided in the water supply lines. Typical application ranges are buildings with irregular use, such as hotels, guest houses, hospitals, schools, gyms, barracks or holiday homes.
The sanitary flush can be controlled cable-free with a smartphone app: the Geberit SetApp. The flush performance can be individually set to up to 2 x 15 litres per minute. Temperature and volumetric flow rate sensors ensure that only the quantity of water actually required is used when flushing. This saves a great deal of water.
The sanitary flush can be connected to a building service management system via different interfaces (RS485 or digital I/O).
Hygiene filter for clean initial filling
To ensure that a new drinking water installation does not become contaminated during the initial filling or a leak test, it must be filled with filtered drinking water. The Geberit hygiene filter retains bacteria and dirt particles, thereby ensuring that only hygienically harmless drinking water enters the installation. Thanks to this, the risk of contamination is eliminated.
Protective caps for clean pipes
To protect the inside of the drinking water pipes and fittings from contamination during storage and transport and on the building site, they are fitted with plastic caps and plugs at the factory. These caps prevent dust and dirt from entering the pipes until they are used.
