Description: Ground Water Protection Zones are areas demarcated in order to protect ground water resources important for current or potential future for municipal bulk water abstraction. They map aquifer vulnerability to groundwater contamination. The intension is to manage land use and limit various of high risk land uses within the zones in order to minimise contamination risks and to ensure the protection of groundwater quality to abstraction boreholes. Five levels of protection zones are defined with reference to groundwater travel times with the highest level being Zone 1 (within 10 meters of the wellhead), followed by Zone 2 (2-year travel time), Zone 3 (5-year travel time), Zones 4 (10-year travel time) and Zone 5 (full catchment area beyond 10-year travel time). Current mapping includes Atlantis and Cape Flats Aquifers and portions of the Table Mountain Group Aquifer relevant for CCT Bulk Water abstraction.
