Introduction Diarrhea remains a leading cause of mortality among children under 5 years of age around the world. The health consequences of inadequate water supplies include an estimated 4 billion cases of diarrhea and 1.87 million deaths each year, mostly among young children in developing countries. Cochrane review of randomized controlled trials revealed that point-of-use water quality interventions could reduce diarrhea episodes by roughly half with some studies resulting in disease reduction by 70% or more.
