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.

Will global warming force a shift in Biel’s drinking water intake? What caused the sudden turbidity of the water supply in the winter of 2009? Eawag has come up with answers to these and other questions for Energy Service Biel, and in the process, new questions have also emerged. Read more

Eawag researchers working on the research project “VUNA” have developed a new recycling process with which nutrients in urine can be harvested and used as fertilizer. In order to further their ideology of sustainable handling of water and wastewater and to work out and implement innovative concepts of water and wastewater treatment, the researchers have founded the Spin-off Vuna GmbH.  Read more
