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

Heavy rainfall can cause flash floods in urban areas. While data from flood events is required to model such phenomena, water levels and discharges are not routinely measured above ground. Eawag now plans to make use of widely available images and videos to estimate these values. Read more

When a person wearing a bright-orange protective suit and carrying a laptop climbs out of a sewer shaft, it could well be an employee of the Swiss Federal Institute of Aquatic Science and Technology (Eawag). Especially if this happens in Fehraltorf. Since 2016, Eawag has been constructing an internationally unique net of sensors that document water circulation in residential areas. 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.
