The global water crisis is underlined by the fact that 785 million people, or one out of every 10 persons, has no access to clean water, while more than two billion people lack proper sanitation due to insufficient water, according to the UN.
Yet, nothing is more essential to life on earth than water. The World Bank predicts the deficit between available water supply and demand will hit 40 percent by 2030 mainly due to climate change and expanding global population.
