An estimated 4 billion cases of diarrhea each year, causing 1.8 million deaths mainly among children under five years of age, are caused by unsafe drinking water, poor sanitation, and poor hygiene. In the development context, five point-of-use water treatment (PoUWT) options - chlorination, flocculant/ disinfectant powder, solar disinfection, ceramic filtration, and biosand filtration – have been shown to improve household water microbiological quality and reduce diarrheal disease in users, and another, boiling, is widely promoted. Based on this evidence, the World Health Organization (WHO) promotes PoUWT to provide safe drinking water for the 884 million people without access to improved water supplies and the millions more drinking microbiologically unsafe water.
