Water-related disease is one of the leading causes of death for children under five in developing countries. This killer takes the lives of more than 14,000 people each day and is responsible for 80 percent of all sickness in the developing world, resulting in 4 to 5 billion diarrhea episodes per year.
 
Impure, unsafe water is a significant health problem in developing countries. More than 1.1 billion people lack access to a reliable supply of safe, affordable drinking water. In many areas, people are forced to use surface waters that contain sewage or other pollutants as their main water source for bathing, washing dishes and clothes, and even drinking water.
 
The global need for safe drinking water goes beyond health issues. Poverty cycles are perpetuated when sickness from contaminated water and tasks such as cutting wood for fuel to boil water steal time from education and productivity.
