South Africa's Department of Water and Sanitation will lift the 15 per cent water restriction it has imposed on municipalities in Gauteng Province in May if the water level in the Integrated Vaal System increases to 70 per cent of capacity.
The Integrated Vaal system, which consists of 14 dams, including the Vaal Dam, the fourth biggest in the country by volume, is currently only 58.3 per cent full despite showing a 4.4 percentage point increase from this time last week following recent good rainfall.
The department's Deputy Director-General, Trevor Bulzer, said Thursday:: "We are going to re-run our analysis to see whether the current inflow matches what we had projected for this hydrological year and in May this year, we will then take the actual decision around restrictions."
However, Bulzer added, "this does not mean we are out of the woods yet".
"We need a substantial amount of above normal rainfall. You will recall in September last year before the flash floods, they put out a warning of extremely above normal and that's the type of thing that we need," he said.
"One of my colleagues sent me a message saying we need another ten rainfalls like what we had in the last week."
He also noted that while some municipalities are managing to cut water usage by 15 per cent, some are failing to do so.
