A recent UN report on global clean water and sanitation suggests that over 40% of the world population still doesn’t have access to safely managed drinking water. The report also reveals that more than half of the world population (4.5 billion) doesn’t have access to a safe sanitation system. It also indicates that almost 2 billion people are using water sources contaminated with sewage.
In short, the noble purpose of delivering clean water and sanitation needs serious attention and innovation. It has to be addressed as soon as possible by combining sustainable development with the intelligent management of infrastructure.
