Groundwater Resource Assessment II

In late 2003, the Department of Water Affairs (DWA) of South Africa initiated the Groundwater Phase 2 Project, which is aimed at the quantification of the groundwater resources of South Africa on a national scale. The project has been carried out by a consortium of consultants comprising SRK Consulting, GEOSS, WSM and CSIR (SGWC) in close collaboration with key DWA personnel and was completed in June 2005. Algorithms have been developed for the estimation of storage, recharge, base flow and the impact of the reserve and present groundwater used has been recorded. The results, in addition to methodology, include several valuable datasets and maps and will provide input to various levels of planning and management of water resources once reviewed and verified. The data, information and paper copies of technical reports can be obtained from georequests@dwaf.gov.za.
