Groundwater Harvest Potential

The map below show the safe abstraction (m3/km2) of the groundwater harvest potential in South Africa. This is an appended coverage created from the following DWAF’s coverages: Saturated Interstices, Mean Annual Groundwater Recharge, Groundwater Quality, Annual Percentile Precipitation and Borehole Yield; used in the mapping of Groundwater Resources of South Africa 1995. The coverage is used to provide a preliminary national quantitative depiction of sustainable rates of groundwater potentially available for abstraction.
