Scottish Water said it was notified of the problem at 10am yesterday and engineers were "working around the clock" to repair the damaged valve.

It comes after two collapses at the demolition site at the former post office building in West Port, which led to residents being evacuated. It is believed the water supply was back to normal yesterday evening.

City centre councillor David Beckett said the water in the area had been off since 5pm on Thursday. He said: "I received quite a few complaints about it. The work going on there made it more difficult to fix the valve."

A spokesperson for Scottish Water apologised for the problem, adding:

"Bottled water supplies have been made available for those people requesting it."
