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

Even though the water we’ve used for washing our hands is barely contaminated, it usually disappears down the drain, never to be used again. A newly developed system allows handwashing water to be recycled, thus not only saving water, but also helping to prevent infectious diseases in developing countries. Read more

Dealing with wastewater right where it is being produced, instead of in central treatment plants, can be more flexible and economical depending on the location. In Switzerland, however, there are very few such decentralised wastewater treatment plants – although, as Eawag researchers have established, there is a surprisingly strong market potential for them.  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.
