We have done various presentations on the design and installation of rainwater harvesting systems to architects and project managers across Southern Africa. We share our experiences and provide advice on installation design. Please find a presentations on our website article. We share our key learnings. It is not at all comprehensive but it is a guide for any person that wishes to start with rainwater harvesting. In summary: if you want to install a rainwater harvesting system that will integrate into the premises' water supply, and operate hassle free for many years, it is worth doing your research and installing well designed and engineered equipment.
