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

Current research projects and programs

An inter- and transdisciplinary strategic research program that strives to develop novel non-gridconnected water and sani- tation 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.
