A new water treatment facility in Arua District, Uganda, started pumping over 400,000 litres of water a day from the Nile River into storage tanks, where it is filtered, treated and tested for quality, before being trucked to nearby Rhino Camp, currently home to 86,000 refugees. At capacity, the plant will treat 1 million litres of potable water per day. Pictures: Tommy Trenchard. Read more about this project.

Water, sanitation and good hygiene: vital components in our global cholera response

Water, sanitation and good hygiene practices are fundamental to healthy life. Our collective aim is to ensure every family has affordable and sustainable access to safe water and adequate sanitation. Despite major progress in this ambition over recent years, the poorest and most vulnerable, especially in countries where government or infrastructure is dysfunctional, still suffer with inadequate facilities. And we know that this is a major factor which causes death or poor health, reduces productivity, impacts upon nutrition and undermines personal dignity.

For example, the provision of safe water and adequate sanitation have been vital in the response to cholera and, as shown in large scale cholera eradication efforts such as in Mexico in the 1990s, tackling this one disease leads to a massive reduction – by more than half – in overall diarrhoeal disease rates. This informs our approach to fighting current outbreaks of cholera and preventing future ones. The best way to deal with present and future epidemics is to bring water and sanitation coverage up to adequate levels, while also working with people and communities to raise awareness of good hygiene practices. It is our first, and perhaps most effective, intervention. Of course, the people most vulnerable to cholera outbreaks are often the poorest.
