Résumé
Physical and economic scarcity of water resources tended towards critical examination of the different water demand and allocation polices and guidelines by various countries in the world. Raw water quality variability is a key issue that was omitted in the gazetted raw water pricing strategy of South Africa. Upon consultation of various stakeholders, a fixed raw water price is stipulated yearly by the Department of Water and Sanitation, formally the Department of Water Affairs and Forestry Regardless of abstracting water of variable quality, all the water boards pay the same price and treat water to the same portable standards. Considering the additional cost requirements of treating poor quality raw water, this implies that, downstream Water Boards are either operating at unreasonable profit margins or transferring the burden to the end users. Under these circumstances, a raw water pricing strategy was developed by the South African government principally to improve effectiveness, efficiency and economic allocation and preserving of water resources. In this study priority attention was being given to the challenges and imbalances of the current raw water pricing system due to water quality variation. The purpose of the study was to modify and incorporate a developed water quality index into the current raw water pricing strategy of South Africa, consequently developing an equitable raw water pricing model.
