SODIS - Safe drinking water in 6 hours

SODIS

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.

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.

Improved physical development

20th of December 2011 – Monika Tobler
School in Kenya

The prestigious Royal College of Surgeons in Ireland, which has been investigating the SODIS method for many years, has recently presented its latest results. Scientists examined the impact of SODIS training courses on the health of Kenyan children aged between 6 months and 5 years. They also considered for the first time the growth of children. The study revealed that children consuming exclusively SODIS-treated drinking water were not only less affected by diarrhoea, but also physically more developed than children of a control group who drank untreated water. The results obtained confirm the long-term positive impact of SODIS projects on children’s health.

In the Kibera slum in Nairobi, our local partner organization is setting up water kiosks for women groups. These will advise their neighbours on drinking water treatment and hygiene issues and sell them products for drinking water treatment and hygiene. In the slums of Nyalenda and Manyatta in West Kenya, the inhabitants are being trained in SODIS use and improved hygiene. There, the project focus mainly on training in schools.

Thanks to the unrelenting advocacy work of our partner-NGO EVE, a memorandum of understanding was signed with the Ministry of Health last year. This further consolidated the collaboration with the Ministry of Health. After government-conducted water tests, which reconfirmed the efficiency of solar water disinfection, the Senegalese authorities now officially recommend the SODIS method. In the Tambacounda region, signing of the memorandum of understanding paved the way to a joint SODIS project with the Ministry of Health.

Partner organisations from SODIS project areas in Asia (Delhi, West Bengal, Tamil Nadu, Assam, Nepal, Laos, Vietnam) met in a workshop in New Delhi on 31 March to 2 April 2011. Focus of the meeting was the exchange of experience with the dissemination of low-cost drinking water treatment methods at household level (particularly SODIS) and improved hygiene practices. The participants developed jointly new strategies for integrated promotion of different technologies and institutionalisation of these approaches in government health and drinking water programmes.

 

Chilled SODIS water – a business idea of Madeleine Djike

28th of February 2011 – Valérie Cavin
Madeleien Djike

Mrs Djike lives with her family in the Song-Mahop slum in Cameroon. She has been selling chilled water to neighbours and travellers for many years. In 2008, a SODIS campaign was conducted in her neighbourhood. A promoter also visited her home and explained the use of the method. Mrs Djike hesitated at first. Considering the poor water quality in her slum, the method appeared to be too easy to work. After placing PET bottles on her roof and testing the method herself, she became an active user of SODIS method. Since then, her family is drinking clean water and suffers far less from diarrhoeal diseases.

After her positive experience with the method, she also decided to offer her customers chilled SODIS water. The good quality of her water got around quickly in the neighbourhood. Today, she proudly says: "With the SODIS method, I already treat more than 40 bottles of water every day, which I chill and sell the next day. Thanks to the good water quality, I have acquired many new customers". Since Mrs Djike also shows her customers how to use the SODIS method at home, she makes a significant contribution towards improving the living conditions in her neighbourhood.
