Just how good is our drinking water?
Switzerland is widely recognised as one of the countries with excellent drinking water. People are proud of the high quality of their tap water, which is said to be superior to mineral water in many places. However, the truth is more nuanced. Due to new challenges brought about by environmental influences and technical developments, it is worth taking a closer look at the quality of our most important foodstuff.
So, how well does Swiss drinking water perform in the current situation?
Strict standards are in place in Switzerland to protect consumers and ensure that water is always safe from the well to the tap at home. The authorities regularly and meticulously monitor water samples to ensure they comply with all the required limits and fulfil the requirements of the Drinking Water Ordinance. Nevertheless, recent research, particularly by environmental protection organisations, shows that some parameters are trending negatively: increased contamination by agricultural pesticides, microplastics in water, and drug residues that are becoming increasingly detectable in drinking water pipes despite complex filtering processes.
In addition, the hardness of the water in many regions is increasingly causing technical problems. Water that is too hard affects not only the taste, but also damages fittings and equipment, shortening the service life of appliances and increasing the consumption of cleaning agents.
Many suppliers now offer remedies. One example of this is special descaling systems. These devices reliably remove limescale and help protect pipes and household appliances in the long term, providing an effective solution to the problem of limescale.
Here are six key points to consider regarding drinking water quality:
- Regularly check water quality via supplier reports.
- Pay attention to visual or flavour changes.
- Use tested water filters or special treatment technologies in areas with hard water.
- Take precautions regarding drug and pesticide residues in regions with intensive agriculture.
- Avoid unnecessary chemicals in the home and garden to reduce long-term water pollution.
- Make informed and conscious use of alternative systems, such as decalcification and softening systems.
The future outlook for Swiss drinking water quality lies between technological progress and environmental awareness.
In the future, Switzerland will continue to pursue the intensive protection of its drinking water resources, combining innovative technologies with growing environmental awareness. An example of this is the ‘Drinking Water 4.0’ project launched by the Eawag water research institute in 2022. Intelligent sensor technology and artificial intelligence enable pollutants to be identified in real time, allowing countermeasures to be taken at an early stage. This modern technology provides efficient ways to safeguard water quality. At the same time, there is growing societal willingness to preserve the natural water cycle and conserve water resources sustainably.
There is a growing awareness of the need for everyone to take responsibility for the future quality of our drinking water.
The quality of drinking water in Switzerland is currently comparatively high. Nevertheless, relevant contaminants such as limescale, residues and pollutants need to be precisely recorded and comprehensively addressed. State-of-the-art developments provide valuable impetus in this area, actively supporting the authorities, suppliers and users in recognising emerging risks in good time and taking the most appropriate countermeasures. In the coming years, the urgent task will be to consistently pursue and implement innovations, while also further stimulating and promoting environmental awareness and personal responsibility within society as a whole. Only by combining these aspects can the high quality of our drinking water be guaranteed in the long term.
