Rand water unveiled South Africa’s largest post-load concrete tank – and possibly the world’s largest concrete reservoir – in Benoni, Ekurholuni on Friday.
A new 210 megaliter capacity cylindrical and circular reservoir is being constructed at Vlakfontein Reservoir as part of Rand Water’s efforts to increase its water supply.
The second largest of its kind is a 200-megaliter tank in Saudi Arabia, Rand water President Ramateu Monyokolo said during a field visit to the near-completed project.
Construction on the project began on May 12, 2020 with an estimated completion date of April 25, 2023.
The Flakfontein reservoir will serve the communities of Pretoria East, Ekurhuleni, Govan Mbeki, Victor Khani, Thembisili Hani and Lisidi.
Seeing a marvel of design, Rand Water CEO Sipho Mosai told site delegates that the newly constructed reservoir will add to Vlakfontein’s existing 420-megaliter reservoir, bringing the site’s total capacity to 640-megaliter, whichwill allow up to 24 hours of capacityprovided there is no pumping challenges or power failure.
The new tank also brings the number of Randwater tanks to 59, with 13 new tanks being built by 2028, increasing the agency’s capacity by 25% from 6,100 megaliters per day to 7,630 megaliters.
This year alone, Rand Water will add 600 megaliters a day, he says.
Rand Water plans to spend over R5 billion on new projects over the next five years to increase its water supply capacity.
