OVERVIEW South Africa is using something between 2-4-million m³ every year, against a potential resource of 7-10-million m³. Extracting groundwater takes skill and money, so it has mostly been neglected but with persistent droughts afflicting the country it is likely to become a much higher priority in water planning. Water harvesting (including installing tanks to collect rain water from roofs) is another area that has not been comprehensively exploited. Innovators and investors in the sector have a lot of scope to develop products and systems to help South Africa secure better water supplies in future.
Infrastructure The first phase of the Spring Grove Dam in the Mooi River area was completed on schedule and increased water supply in the Umgeni River catchment area. Spring Grove takes to five the number of dams in the MooiMgeni system (including Midmar, Albert Falls, Nagle and Inanda dam), which serve more than five-million people in Durban, Pietermaritzburg and surrounding towns. When Spring Grove is complete, the total system yield will rise to 394-million m3/year. A new dam is being built at Smithfield and the wall of the Hazelmere Dam is being raised to increase capacity. A new reservoir (Waterloo) near the King Shaka International Airport, and serving this northern area, has been constructed as part of the master
plan that will see water delivered to this reservoir from the Northern Aqueduct Augmentation Project. The Western Aqueduct project (valued at R864-million) and the associated Northern Aqueduct Augmentation Project will inject water into the rapidly developing area north of Durban. The Tugela Bulk Water Scheme (valued at R1.4-billion) will supply water to KwaZuluNatal’s North Coast.
Water boards Talks have begun to rationalise the province’s water boards into one body. The aim is to achieve economies of scale and efficiency and to make it easier to raise funds for large projects. Umgeni Water currently supplies potable water to its six large municipal customers: eThekwini Metropolitan Municipality, iLembe District Municipality, Sisonke District Municipality, Umgungundlovu District Municipality, Ugu District Municipality and Msunduzi Local Municipality. The company has five dams, 10 waterworks, five watertreatment plants and two waste-water works. Large parts of the northern part of the province are served by Mhlathuze Water. The utility has assets valued at more than R3-billion and its area of supply covers 37 000m². The Bill & Melinda Gates Foundation has made a difference in the lives of 200 households in the uThungulu District by making clean water available. This project was facilitated by Trade & Investment KwaZulu-Natal. Nedbank is putting R9-million over five years into clearing alien vegetation in the country’s water-catchment areas, including in KwaZulu-Natal. The Nedbank sponsorship of the WWF’s Water Balance Programme has seen water flowing more freely in the Umgeni catchment area. The WWF Nedbank Green Trust is one of the major sponsors behind the Dusi Umnengi Conservation Trust, which works for the environmental health of the Umnengi and uMsunduzi Rivers. A Green Corridor initiative is one of the projects.
