Overcoming Water Scarcity With Dynamic Water Flow Rate Control (DWFRC): Case of South Africa

South Africa (SA) being a high water-stressed country, the demand is expected to grow by 17% in 2030. Besides these problems, over 37% of water in the urban piped system leaks out or is used illegally. This compounded effect poses a serious threat to the future of the SA country as a whole. In view to partly mitigate to this alarming consternation, this work presents a dynamic water flow rate control (DWFRC) model which could be used to alleviate the water scarcity problem faced by the world. Using SA context and standards, an investigation is first performed to understand the current water reticulation system. Thereafter, the excessive pressure problem is identified, and a DWFRC solution model is provided. The model is implemented in MATLAB, and simulation result demonstrated the ability of the model to conquer excessive water pressure at all times, thereby ensuring a long-lasting water reticulation system. Not only will this work helps fight water scarcity and combat non-revenue water problem, it will additionally help achieve efficient use of water management and storage.
