Each year, nearly one billion people around the world lack access to safe, clean water [1]. Water is essential for life, yet less than 1% of water on the planet is safe to drink. This is especially a problem in developing countries or during natural disasters. Take Hurricane Katrina: back in 2005 when it hit the Gulf Coast, one of the biggest needs for storm victims was access to clean drinking water.
In the United States and Europe, people take it for granted that when they turn on the faucet, clean water will flow out. Indeed, a single flush of a toilet in the West uses more water than most Africans have to perform an entire day’s washing, cleaning, cooking and drinking [2].
Securing access to safe water worldwide is vitally important. Clean water is essential for agriculture, food and energy production, recreation and reduction of poverty. More than 2 million people, most of them children, die every year from water-borne diseases. And time is of the essence: by 2020, more people could die of water-related diseases than those that have died due to HIV/AIDS [2].
