Drinking Water

Prevention is better than cure

Thanks to the fact that Switzerland’s surface waters have been kept clean, this maxim has to a large extent been upheld. However, the presence of new (harmful) substances allows no room for complacency on this front. Globally, there is an urgent need for cost-effective and energy-efficient water treatment solutions on various scales - all the way through to wastewater recycling.

Although bacteria are an inevitable – and important – component of drinking water, the colonization of pipes by pathogenic organisms can lead to microbiological quality problems. However, according to an Eawag/HSLU project co-funded by the Commission for Technology and Innovation (CTI), various measures can be taken to minimise this risk.  Read more

Compared to other foodstuffs, Switzerland’s drinking water shows low levels of contamination with antibiotic-resistant bacteria or resistance genes. This was demonstrated in a study of eight drinking water systems carried out by Eawag researchers on behalf of the Swiss Gas and Water Industry Association (SVGW) and water suppliers. Read more
