Effective WASH with SODIS and WADI
Reducing the incidence of waterborne diseases through sustainable behavioural changes in water, sanitation and hygiene (WASH) practices and the use of solar water disinfection (SODIS) with WADI.

WADI has significant poverty alleviating benefits
The project seeks to provide an effective and sustainable behavioral change in water, sanitation and hygiene practices for a community of nearly 19.000 people in the Eastern-Ugandan district of Soroti. Project funds were raised during a Christmas Call in 2016 by the German alternative energy co-operative Elektrizitätswerke Schönau (EWS). A particular focus of the project is to reduce the incidence of WASH related diseases by improving access to safe drinking water using SODIS (Solar Water Disinfection) and the WADI device. The method employed by the implementing partner Water School Uganda is an empirically proven WASH intervention with an 86% retention rate, which will be introduced into four parishes of Gweri Sub County in Soroti District. It will include the establishment of pit latrines, hand washing facilities and a compost pit in every school and household of the intervention area. It will also include the construction of eight 10.000L rainwater-harvesting tanks in the four schools.
Uganda reports 400 deaths daily from various waterborne infections - including diarrhoea, dysentery, cholera and typhoid. The most invisible killer diseases are due to contaminated drinking water and poor hygiene, which can be easily prevented through the methods employed during this project. More than 3.000 households and 2.200 school pupils are expected to reap benefits from the sustainable behavioural change that will be the result of this intervention. Furthermore, creating access to safe drinking water using SODIS and the WADI has significant poverty alleviating benefits as the number of missed days at work is diminished, expenditure for medical treatments is reduced and the need to buy or collect fuel to boil water is eliminated. The project will also contribute to the reduction of CO2 emissions as the dominant method for water purification in this region is currently boiling water on wood fires.
The considerable involvement of the local government in this project, including the district health team, as well as the ministries of water, environment and education, promises not only a high degree of project acceptability, but also opens up the opportunity for further scaling up of coverage, both through promoting the WADI and the WASH intervention methodology employed.
