Critical water project gains nod to start

December 2020

It’s all systems go for Phase 2 of the Mokolo Crocodile Water Augmentation Project (MCWAP-2) following the finalisation of the environmental authorisation process. The multibillion project had hit a snag after some stakeholders appealed an earlier official nod for construction to commence.

MCWAP-2 is one of the biggest projects in the TCTA portfolio and promises considerable economic spin-off for the country. At April 2018, the project had an estimated cost of R12,3 billion and benefits including job creation and socio-economic development.

Its greatest import, arguably, lies in the part it will play in assisting the country to overcome the electricity shortage crisis behind the routine occurrences of load shedding across the country. MCWAP-2 will create a second water source for Eskom to run its two power stations, Mdupi and Matimba, which constitute 20% of the country’s energy capacity. (Read more)
