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

River sediment normally acts as a sink for hormones that are dissolved in the water. However, if they are disturbed, for instance when flooding occurs, these substances can end up back in the water column – with potentially negative consequences for the whole ecosystem. Read more

Treating community wastewater takes a lot of energy. Eawag is currently supporting a project that not only presents an alternative to conventional treatment processes but is also designed to enabled increased throughput within a smaller amount of space. Read more

Selected research projects and focus areas

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.
Eawag has a long history of developing innovative processes for separating wastewater at source. These technologies include one whereby urine is separated out using the NoMix Toilet.
