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.

It is well known that Legionella bacteria can contaminate drinking water systems in buildings. A case study published in Aqua & Gas by Eawag and the Lucerne University of Applied Sciences and Arts now shows how they can be controlled by different temperature strategies.

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.
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
