About 26% of water is lost through leaks and bursts.
Yesterday, the water utility met with ward councillors, from wards 58, 69, 86 and 87, to discuss immediate and long-term measures to stabilise supply, such as the construction of the new Brixton reservoir and tower, to be completed at the end of October 2025.
On Thursday afternoon, Dada Morero, the Mayor of Joburg and Jack Sekwaila, MMC of Environment, are expected to brief media about next steps, in the crisis, as more suburbs in the south of Joburg, have little to no water.
Rand Water said municipalities in Gauteng are guzzling down 80% of water it abstracts.
