- Description
- South Africa is classified as a semi-arid country, with annual average rainfall well below global standards. It experiences drastic fluctuations in rainfall, with as little as 100mm on the western side, to as much as 1500mm per annum on the eastern side (DWA, 2013a). At the end of 2015, 65% of South Africans were living in urban areas (Worldbank.org, 2017), a phenomenon that places severe pressure on the already strained water resources in the country. Among the most common natural causes of water shortages are drought, climate change and evaporation, while disparity in water supply, urbanisation and population growth, illegal tap connections, and contamination of water sources rate among the main human causes (Machethe, 2011). These natural and human causes, combined with the economic importance of water, highlight the importance of well-maintained water infrastructure to a developing nation such as South Africa. Membrane Bio-reactor technology (MBR) has been applied successfully in many developed countries around the world and, because of the superior quality effluent associated with this technology, it has the potential to contribute to the maintenance of the water ecosystem in South Africa in a positive and sustainable manner. The aim of this study is to investigate the contribution that MBR technology can make towards alleviating the water crisis in the South African context. The study made use of a case study methodology with embedded units of analysis in the form of semi-structured interviews, in order to conclude that MBR technology has a very significant role to play in the longevity of water resources in South Africa – especially when it comes to water re-use in densely populated urban and developed areas. The financial feasibility of such technology could however not be measured accurately, as this aspect depends largely on the application needs of the specific water authorities.
