JOHANNESBURG - In a water scare-country like ours, every drop of water counts and the University of Pretoria acknowledge this.
That's why it has installed an innovative rooftop rainwater collection system by transforming some of its parking lots into water harvesting points.
Jason Sampson, curator of the university's Manie van der Schijff Botanical Gardens, says that harvesting is simple when it comes to storage and purification.
