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.

April 14, 2022Chlorination of drinking water reduces infections – and it changes the composition of the intestinal flora of young children, as a study published today in “Nature Microbiology” shows. The results indicate that the diversity of the intestinal flora isn’t reduced and bacteria associated with gut health are increased.

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)
Sustainable urban water and wastewater management applied and implemented in the modular NEST building.

Regionale Wasserversorgung Basel-Landschaft 21

SWP assesses recontamination risks in treated water and evaluates strategies to prevent it: safe storage options, UV-C disinfection in storage containers and passive system-level chlorination.
With Helvetas-Nepal, this project aims to establish a drinking water security strategy in rural communities
