Water, sanitation and hygiene

3ie’s has two major evidence programmes that support the generation and use of high-quality evidence for informing decision-making in the water, sanitation and hygiene sector (WASH).

What factors affect sustained adoption of safe water, hygiene and sanitation technologies?

Systematic review summary 3ie 2015
Safe water, sanitation and hygiene (WASH) behaviours, such as treating drinking water, washing hands at key times or using a latrine rather than defecating in open spaces, are cornerstones of building strong, healthy communities and reducing mortality due to diarrhoea and other preventable diseases. Many studies have shown the health benefits of WASH, and factors that affect initial adoption of short-term WASH use. Few have assessed the determinants of long-term, sustained WASH practice.

Systematic review Brief 3ie 2012
Treating water can reduce the prevalence of diarrhoea by up to 70 percent. Although there are several inexpensive water treatment technologies available, statistics show that every 15 seconds a child dies due to waterborne diseases. Over 700 million people still lack access to safe drinking water.
