Wastewater

Optimise and overcome new challenges

The wastewater infrastructure in Switzerland is worth 125 billion Swiss francs. Nine hundred treatment plants clean the country’s wastewater around the clock. Part of the work of Eawag is to examine how this success story can be continuously optimised and tailored to suit the particular conditions in other countries, as well as to look at how to overcome new challenges

Hanspeter Zöllig has been awarded the 2016 Otto Jaag Water Protection Prize for his dissertation entitled “Electrolysis for the Treatment of Stored Source-Separated Urine”, which examined how electrolysis can be employed to recover nitrogen from urine. The prize recognises excellent PhD theses and masters dissertations in the fields of water protection and hydrology. Read more

Current research projects and programs

Wings is an inter- and transdisciplinary strategic research program that strives to develop novel non-grid-connected water and sanitation systems that can function as comparable alternatives to network-based systems.
The National Research Programme "Sustainable Water Management" (NRP 61) developed scientific foundations and methods for sustainable management of Switzerland's water resources.
