Rand Water is adding 100 million litres to Johannesburg's water system to help improve the Roodepoort reservoirs and water towers, but Johannesburg Water said it would still take a few days to fully recover.
On Thursday night, Johannesburg Water said there were some improvements in most systems, but it would intervene overnight with reservoirs and towers in the western parts of the city, which were still struggling.
Meanwhile, Ward 99 councillor Nicole van Dyk said she feared water would only return next week.
