Document Precis:
40% of South Africa’s population lives within eight metropolitan municipalities and utilises approximately 48% of the total urban water supplied, or 11% of the total water consumed. The Department of Water and Sanitation (DWS) regards water conservation and water demand management (WC/WDM), from a water resource perspective, as a key intervention in municipalities. Since WC/WDM is critical, and, in order to monitor municipal performance on an on-going basis, the DWS Water Services Directorate: Macro Planning,in consultation with the DWS Water Resource Planning Directorate: Water Use Efficiency, continually accesses municipal water balance information, a process that started in 2004/5 and more recently culminated in the No Drop process. This metro specific report contains the most detailed water balance data from 2004/5 to 2013/14. All calculations are based on the International Water Association (IWA) standard water balance model as modified slightly for South African conditions.
