South Africa’s battle to find enough water to feed its industries and households is going to get tougher – and the country’s economic hub, Gauteng, is especially threatened.

“If the Katse dam drops anywhere near 25% of capacity there will be hell to pay, because Katse feeds all of Gauteng. It also feeds the cooling systems of the Mpumalanga power stations, which provide up to 95% of South Africa’s power.
“If we can’t keep those power stations cool with millions of litres of water an hour, there will be blackouts.”
Water expert Anthony Turton, said of the dams’ levels: “The [Lesotho Highland Water project] is the water tower of Gauteng.”
Turton said that once a dam had fallen to 60% of its capacity the decrease from then was rapid.
