Harvesting rainwater in South Africa on my a 10 000L storage platform using molded tanks, leaf diverter, and a first flush system. If you are interested in setting up your own rainwater harvesting systems at home WATCH this video first! It is possible to design a rainwater harvesting system that can harvest rainwater off of almost any structure at relatively high efficiency. In this video, I have used my 10 000L storage platform to explain the process of understanding, collecting, and using rainwater in my context in South Africa. Jojo and Roto tanks are both made in South Africa and are readily available throughout the country.
