Melbourne Water spokesman Nicolas McGay said a faulty valve in the pipeline, which ran from Silvan Dam into the Waverley area, was believed to be responsible for the spout. He said the damaged section of the pipe had been shut down while Melbourne Water staff attempted fix the problem, however customers’ water supply in the area was not being affected.
Mr McGay said about two million litres of water - or 0.002 per cent of Melbourne’s daily water use - was lost when the water pipe burst.
"At this stage it's believed that a faulty air-ball valve, a valve which regulates pressure in the main, caused the burst," he said. He said there had been one report of property damage to Melbourne Water. "We’re working with residents to determine whether there has been any other damage," he said.
Mr McGay said the section of the 50-year-old main had no history of failure, and had an expected lifespan of about 100 years.
