The students gathered knowledge about the challenges associated with water as a resource and the possible solutions on eleven different excursions. At the Forum Chriesbach and the research platform Nest they learned how a sustainable handling of building materials, energy and water is possible in practice. Eawag, for example, saves water and wins valuable nutrients from urine with its urine-diversion toilets.
Eawag researchers and other national and international water experts helped the students to understand the complex and interdisciplinary subject area and to define problems. Eawag researchers who contributed to the ETH Week were Bernhard Wehrli, Eberhard Morgenroth, Max Maurer, Christian Zurbrügg, Isabell Köpping, Urs von Gunten, Klement Tockner, Andrea Popp, Roni Penn, Sabine Hoffmann, Ulrike Feldmann, Regula Meierhofer und Max Friedrich.
After six days of intense work, three of the 18 projects presented were selected for awards. The prize for the most inspiring story went to the “Save-o-Pillar” project. The apparatus developed animates the consumers with positive feedback in order to reduce their virtual water use.
The award for the most fascinating science was won by the project “Make grey water great again”. The idea of using shower water once again to flush the toilet can reduce water consumption in private households by 20%.
The award granted by the students went to the project “Smart Fish”. In this project, fish with attached sensors can collect geoecological data in Swiss waters.
