PROJECT: KWSAP OVERVIEW

Komati Water Scheme Augmentation Project (KWSAP)

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.

Project Profile

The Komati Water Scheme Augmentation Project involves the construction of:

• an additional pump station at the Rietfontein Weir with a total flow rate capacity of 2,16 meters cubed
• A 1 100-mm nominal-diameter steel pipeline from Rietfontein Weir to the Duvha Power Station over a distance of 58,4 km with a flow rate capacit y of 1,684 cubic meters per second; and
• A 600-mm nominal-diameter steel pipeline from Rietfontein Weir to the Matla Power Station over a distance of 12,9 km with a flow rate capacity of 0,474 cubic meters per second

The additional water yield is expected to be approximately 57 million cubic meters

Funding

The Minister of Finance, with the concurrence of the Minister of Water and Environmental Affairs, approved a project budget of about R1 700 million funded on an off-budget basis. The capital costs will be recovered from the revenue generated by the sale of water to Eskom over a 20-year period after commissioning.
