Drinking Water

Prevention is better than cure

Thanks to the fact that Switzerland’s surface waters have been kept clean, this maxim has to a large extent been upheld. However, the presence of new (harmful) substances allows no room for complacency on this front. Globally, there is an urgent need for cost-effective and energy-efficient water treatment solutions on various scales - all the way through to wastewater recycling.

Legionella in drinking water systems can pose a health risk. But the complexity of the stagnation issue means that a much more nuanced approach is required to manage this risk than has previously been supposed.

Selected research projects and programs

Inhalation of legionella bacteria – which thrive in warm water – can cause illness: in a new project, an Eawag-led multidisciplinary research team is investigating how the risks associated with these bacteria can best be managed.
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.
This project facilitates the exchange of data, maps and information on geogenic contaminants (focussing on arsenic and fluoride) via the web-based Groundwater Assessment Platform (GAP)
