The Microbiology department at the University of Stellenbosch has undertaken a project to harvest rainwater, treat it and make it potable (drinkable). The project is being tested using three solar pasteurisation tanks along with with the cooperation of people from 10 homes in the informal settlement of Enkanini in the Western Cape.
Currently, the water is not drinkable as indicator organisms are present in the water. These organisms are being tested to discover whether they are disease causing. The water is however being used for cleaning in homes and laundry.
