February 16, 2023A new “Theory of Change” shows which psychological factors influence the use of decentralised water treatment technologies and which measures can support their introduction.

January 20, 2023Environmental DNA analysis of microbial communities can help us understand how a particular region’s water cycle works. Oliver Schilling, Professor at Eawag and the University of Basel, recently used this method to examine the water cycle on Mount Fuji. His results have implications for Switzerland as well.

November 22, 2022New technologies in the water sector can contribute to the flexible and sustainable development of urban water management and the sustainable utilisation of water as a resource. In a recent article in the journal Aqua & Gas, a team of researchers from the aquatic research institute Eawag shows what opportunities and risks are associated with this.

November 17, 2022No tiger duck and no football club - the formula "yellow-black-grey" refers to the separation of wastewater streams at their source, i.e. at the toilet, washbasin or shower. This opens up new possibilities and saves resources. On the occasion of World Toilet Day on 19 November, a series of Eawag fact sheets shows how this can be done.

September 16, 2022The “Water Wall” developed by Eawag researchers recycles handwashing and toilet flushing water in a closed cycle and can therefore be used in regions with scarce water resources or those without water and wastewater networks. Now the project has been awarded the Mülheim Water Award.

August 4, 202225 years ago, urine-diverting toilets were no more than an idea, challenging the central paradigm of wastewater treatment plants. Since then, however, modular water technologies have become increasingly important. Using a new method, scientists at Eawag have mapped the dynamics of this transition.

July 28, 2022Over the last six years, more than 160,000 people around the world have participated in online courses offered by Eawag, thus acquiring valuable knowledge about, for example, sanitation systems or municipal solid waste management.

June 9, 2022Eawag’s research is usually reported on in scientific papers and media articles. Rather unusual, however, is the form of a comic. Illustrator Celine Künzle took a close-up look at Eawag’s research with faeces and recorded her impressions in the recently-published comic report.

April 14, 2022Chlorination of drinking water reduces infections – and it changes the composition of the intestinal flora of young children, as a study published today in “Nature Microbiology” shows. The results indicate that the diversity of the intestinal flora isn’t reduced and bacteria associated with gut health are increased.

April 12, 2022Eawag is taking its experience with the treatment of faecal sludge in low-income countries and applying this know-how in Switzerland. The aim is to develop solutions that allow wastewater to be used as a source of energy and nutrients.
