"Through our work, we are trying to improve the supply of drinking water and reduce infant mortality, and thereby make a direct contribution to the millennium development goals of the UN."

"We hope to achieve these goals by spreading the SODIS (Solar Water Disinfection) method that was developed by Eawag researchers. An enthusiastic team in Switzerland provides technical support and high quality project management for SODIS projects in 24 countries. The projects are run by professional local partner organisations. With publicity campaigns, we work to persuade governments and development organisations to commit to ensuring that everyone has access to clean drinking water."

"Eawag supports the improvement and spread of the SODIS method through research in microbiology, health, educational strategies and PET bottles. However, the field work in individual SODIS projects is not part of Eawag's core business. This is why the money for promoting the SODIS method must come from donations."

Solar water disinfection - the SODIS method - is a simple procedure to disinfect drinking water. Contaminated water is filled in a transparent PET-bottle or glass bottle and exposed to the sun for 6 hours. During this time, the UV-radiation of the sun kills diarrhoea generating pathogens. The SODIS-method helps to prevent diarrhoea and thereby is saving lives of people. This is urgently necessary as still more than 4000 children die every day from the consequences of diarrhoea.
