6 ’s Water Resource Scarcity (average annual rainfall & water resource situation)  Rainfall is relatively higher in the northern and eastern parts of Southern Africa (viz. DRC, Zambia and Mozambique)  The drier parts of the region include Namibia, Botswana and South Africa  Hence, water availability is spatially skewed (in terms of areal distribution)  Evaporation rates exceed precipitation mainly due to high temperature  Southern Africa only has 12.25% of the total water in Africa (i.e. highly arid region) Key message: RSA is relatively water scarce under natural conditions even before factoring human induced impacts into the equation South Africa’s water resources

Surface Water Potential Ground Water Potential

Total Runoff = 49 billion m3/year (<50% of Zambezi river) Total potential = 19 billion m3/year Reliable yield for use = 10,2 billion m3/year (27% of runoff) Utilizable potential = 5 billion m3/year Remaining development potential = 5,4 billion m3/yr Economical use is less due to size & location Potential re-use of return flows = 1.9 billion m3/yr Current est use = 2-3 billion m3/year

10 Bulk Supply System . The GCR is geographically located on a high plateau far from large rivers . The top of the plateau (Parktown ridge) represents a watershed: . Water that falls to the south of the ridge drains to the Atlantic Ocean (via the Vaal and Orange Rivers) . Water that falls to the north of the ridge drains to the Indian Ocean (via the Crocodile and Limpopo Rivers) Bulk Supply System . Due to the watershed, the GCR extracts from and impacts on a number of water management areas Bulk Supply System . 83% of the GCR’s water is supplied by a complex system of transfers through the Integrated System (IVRS)

17 Reconciling Water Requirements & Availability

• DWS undertakes scenario planning to ensure water security for the country • Key outputs of the scenario planning are strategies to reconcile water requirements and availability for all large integrated systems in the country as well for localised water resource systems that secure water for small towns, villages or clusters of settlements. • Due to the dynamic nature of a water balance for a system, reconciliation strategies must be continuously reviewed and updated in a participatory manner. Strategy Steering Committees involving stakeholders/roleplayers/ interested and affected parties are formed to oversee this task. • Reconciliation strategies feeds water security perspectives into national, provincial and local planning instruments such as the NDP, NWRS, PGDS, WSDPs and etc. • Reconciliation Strategies thus underpins water and sanitation master planning in SA including the Water Sector Infrastructure Investment Framework which is critical for economic revival and growth.

18 Reconciliation Strategy for the Integrated Vaal River System

Water Description of the system and its Strategic Interventions to keep the system in Resource (WR) supply area balance for a period of at least 25 years System

Integrated Vaal • Consists of 14 interlinked dams • Eradicate unlawful irrigation, notably in the River System including Vaal, Bloemhof, upper Vaal river area Sterkfontein, Grootdraai, Katse, • Implement Water Conservation/Water and Mohale Dams Demand Management with focus on loss • Supplies water to: 60% of management (15% must be saved) economy, 45% of population, • Treat and use effluent, starting with Mines and industries on Eastern desalination of acid mine water drainage Mpumalanga Highveld, Bulk of • Implement the next water supply Eskom’s coal fired power stations, augmentation scheme (Phase 2 of the Sasol’s coal to liquids plants, Lesotho Highlands Water Project) Gauteng, North West and Free State goldfields, Kimberley, Large irrigation schemes, • System in currently in deficit due and needs augmentation

54 Westonaria Regional Sanitation Scheme (WRSS) • The project is part of the then Westonaria LM now merged with Randfontein LM to form Rand West City LM. • It aims to provide additional waste water treatment capacity within West Rand due to anticipated number of developments in the area. • The Scheme consist of the following projects:  Adding 15 Mℓ/day to the existing 22Mℓ/day at Hannes van Niekerk WWTW. The project has been completed.  Build new 80 Mℓ/day Zuurbekom WWTW in 4 phases of 20 Mℓ/day modules due to financial constrains. However the first phase will also see the construction of the 40Mℓ/day Head of Works with peripheral structures.  Build Mohlakeng (Westonaria) Pump Station and pipelines linking the two WWTWs (Hannes van Niekerk and Zuurbekom) as well as rehabilitation of Emergency Pump Station.  Construct bulk pipelines to Syferfontein housing development.
