Systems dynamic of portable water shortage in the limpopo province of south africa

Limpopo is the hottest Province in South Africa and has less percentage of rain to fill up its dams and rivers. There is a higher chance for the communities to run short of water because the used water is not recycled. The villages use pit toilets, therefore, it becomes difficult to have a water recycling plant. The purpose of this study is to model the water supply chain to determine the solution for water delivery in rural areas of the Limpopo Province. A system dynamic model is developed using Vensim software. The system is simulated to develop a solution to water crises in the province. The systems dynamics modelling is discussed herein. The Vensim Model was to capture the interaction between the source of water, water treatment plant, water recycling, potable water transmission, commercial and domestic water distribution. The results show that the building of infrastructure for portable water without recycling plant, will partially solve the crisis of water shortage in the province. The recycling plant is found to be helpful in saving water for future purposes.
