The R1,6- billion flagship Berg Water Project in Franschhoek augments the supply of water to the City of Cape Town. In March 2009 it was officially inaugurated by former President Kgalema Motlanthe. It was mandated in May 2002 and became operational in December 2007.

The Komati Water Scheme Augmentation Project (KWSAP) has been designed to resolve the water supply problems to Eskom's Duvha and Matla power stations in Mpumalanga. It augments the Komati Water Scheme from the Vaal Eastern Subsystem for the sole benefit of Eskom.

The Lesotho Highlands Water Project was instituted as a bi-national project spanning the borders of South Africa and Lesotho in accordance with a treaty signed in 1986. This almost miraculous engineering feat diverts water from the Senqu River System in Lesotho to South Africa's economic hub, the water-stressed Gauteng region.

The project will be implemented in two phases. Phase 1 comprises a pump station and a 45-km pipeline. The approximately one-metre-diameter pipes will deliver 30-million m3 bulk water per year from the Mokolo Dam.

The project is located in the Olifants River catchment incorporating the Steelpoort River catchment area, and extends into the Mogalakwena and Sand River catchments. Within this region are the towns of Mokopane, Burgersfort, Steelpoort, Roossenekal, Jane Furse, Polokwane, Lebowakgomo and the rural communities of the Lepelle-Nkumpi, Fetakgomo and Greater Tubatse municipalities.

The Mooi-Mgeni Transfer Scheme Phase 2 (MMTS2) to be constructed in the KwaZulu-Natal midlands calls for the construction of the Spring Grove Dam and associated infrastructure to augment the yield of the Mgeni System by 60 million m cubed per annum to a total of 394 m cubed per annum.

One of South Africa's largest water supply projects, the Vaal River Eastern Subsystem Augmentation Project (VRESAP) was declared operational in June 2009 when water delivery from the project commenced. The water delivery timeline was expedited by installing a temporary floating pump station as an interim measure, pending completion of the permanent abstraction works which were delayed.
