Let’s start with ourselves: the human body is 70% water, and we use water every single day of our lives. We need an average of between 50 to 100 litres of water per day, considering 50 litres an intermediate amount and 100 litres optimal access per person per day.
Although water is the most abundant resource on the planet, only 3% is fresh water, of which just 1% is available for drinking. This means 1% of drinking water for a world population of 7.4 billion (as at December 2016); where 663 million people have no access to drinking water and it is estimated that the global demand for water will increase by 50% by 2030.
