where does south africa's water come from
Water supply and sanitation in South Africa Total annual water withdrawal was estimated at 12.5 km3 in 2000, of which about 17% was for municipal water use.[6][7] In the northern parts of the country, both surface water and groundwater resources are nearly fully developed and utilised. In the well-watered southeastern regions of the country significant undeveloped and little-used resources exist.[6] The Gauteng area around Johannesburg, which is very water scarce, receives water from various dams in the area such as the Vaal Dam and imports water from the Orange River system through the Lesotho Highlands Water Project, in particular from the Katse Dam.[10] Cape Town receives its drinking water from an extensive system of rivers and dams, including the Berg River Dam.
South African wine The Constantia Valley is located south of Cape Town on the Cape Peninsula that juts out into the Atlantic Ocean. Because of its location, the region receives oceanic influences on each side that create a cooling effect contributing to a long, slow ripening period in the summer where average daily temperatures fall between 18–19 °C (64–66 °F). Winters are often moderate and mild but wet with annual precipitation usually over 1,000 millimetres (39.37 in). The soil of the region is composed primarily of Table Mountain sandstone with high concentrations of loam and granite.[4] The area grows a wide range of grapes with Sauvignon blanc being particularly noted.[5] The area is now home to 11 wine farms (Andrews, 2017). It is the oldest wine-growing region in the country, with the farm Groot Constantia being the oldest wine estate.[7]:77
