The long run of hot weather in Melbourne has led to a spike in water use.
In the past week, the average per person daily water use reached a record high of 248 litres.
John Woodland from Melbourne Water says it is because of the dry summer.
"We've had eleven weeks of below average rainfall and you do expect these spikes when you do have dry and hotter weather," he said.
He says there is no major concern because over time, water use is falling overall.
"If you look at the 1990s, Melbourne used about 478 billion litres of water a year. If you look at the [last] five years it was 368 billion litres of water per year," he said.
"Despite all the growth in Melbourne and all the additional people, we're actually using less water in absolute terms."
