• MCWAP 1 : Pipeline & Pumping station from Mokolo Dam to Lephalale area (46 km). Packaged initially as a stand-alone-project to expedite water delivery but will be incorporated with MCWAP-2 into MCWAP system

• MCWAP 2 : Abstraction works and pumping station in Crocodile River (West) near Thabazimbi & pipeline to Steenbokpan and Lephalale (157 km).

• MCWAP 3: 83 km pipeline – only if river conveyance losses are excessive.

• MCWAP 4: Transfer scheme from Johannesburg KlipRiver wastewater treatment works to head waters of Crocodile River – only if surplus in Crocodile West is insufficient.

Objective: Water augmentation project to supply demands in the Waterberg Coal Fields (Eskom, IPP’s, associated mining & urban development), utilising available yield of the existing Mokolo Dam and surplus return flows from Gauteng being discharged in the Crocodile River (West ) Catchment.

• Mokolo Dam ( Existing supply): MCWAP-1– Yield increased due to switch from irrigation to game and cattle farming– Raising assessed but not found as preferred option due to dependancy on single source and International Protocol requirements

• Return Flows in Crocodile West River (Future supply -indirectly imported via Vaal River system): MCWAP-2– Availability assessed in Reconciliation Strategy

• Augmentation from Vaal River (if needed): MCWAP-4• Further options

– Groundwater: limited availability– Re-use of local return flows

Project Features

• Abstraction Works on the Crocodile River (West) at Vlieëpoort near Thabazimbi

• Low lift pump station and pipeline to convey water to the balancing dams and appropriate sediment disposal facilities.

• High lift pump station and rising main pipeline (approximately 29 km) to the break pressure reservoir – provisional capacity 110 million m3/a

• Gravity main pipeline (approximately 128 km) from the break pressure reservoir to terminal points close to Medupi Power Station and Steenbokpan

• River management system to manage abstractions from, and the river flow in relevant parts of the Crocodile River (West) catchment upstream of Vlieëpoort Weir

The Supply of and Demand for Water in the Limpopo Valley

Presented by:Lesiba Tloubatla / Bernie Badenhorst

12

Supply of and Demand for Water in the Limpopo Valley

• Different users• Agriculture Irrigation and game farming• Mines• Industry• Primary Users• Environment

13


• Sources• Limpopo River• Sand River• Nzhelele River• Nwanedi River• Mogalakwena River• Groundwater

14


• DWA actions• Nzhelele Implementation Ready Study (IRS)

- PSP appointed to do IRS - Water logged irrigation fields- Exchange water from downstream users- Raise Mutshedzi Dam

• Musina to Africa strategic supply hub initiative (MUTASSHI)PSP appointed to do IRSProgress

15


• Mining development largely uncertain- Who, where, when, how big- Determine water demand- Negotiate for source- Agreements- Funding

• Form a Joint Water Forum (JWF) of mines
