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

3 billion people worldwide live in cities without sewers or wastewater treatment plant infrastructure. This forces them to dump their waste into open waters, contaminating the drinking water for others downstream. Christoph Lüthi shows how we could harness nutrients in wastewater instead of harming human and environmental health. Read more

Making environment-related decisions can be a complex business. A wide range of stakeholders need to be co-opted, different options need to be assessed and the impacts and consequences estimated. In order to also include the opinions of the wider public, Eawag has developed a new app that features elements of gaming. Read more

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.
