SODIS - Safe drinking water in 6 hours
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-causing
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.
SODIS (abbreviation of Solar Water Disinfection) is an
initiative of Eawag. We facilitate the dissemination of the SODIS method in
developing countries. Thereby people in the south get access to safe drinking
water and can improve their health in the long term.
