Drinking water hygiene with Geberit Safely prevent stagnation
Biofilms in drinking water
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:
- correct planning, design and commissioning
- correct operation
- preventing stagnation
- preventing unfavourable temperatures between 25 °C and 50 °C
Underestimated risk: legionella and pseudomonas
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.

Standards and laws
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.
