In the last decade, natural disasters occurring in human populated areas have increased in both frequency and intensity. These events often damage vital infrastructure, including drinkable water delivery systems, utility services and access to critical medical care a nd equipment. There is an urgent need to deploy life saving water in areas stricken by such disasters.
Flash floods, torrential downpours and levee failures result in large scale flooding and evacuations. Emergency clean water sources can be contaminated and often become vectors for disease such as cholera and dysentery. Ground water and surface water cannot be utilized, often for weeks after flood waters subside.
