As our dry summer continues, and with repeated warnings over reservoir levels, Jersey Water says it's expecting islanders will use 160 million litres during next week's warm weather.
That is almost as much water as is currently in Grands Vaux reservoir.
The utility is reminding us all to reduce how much water we using, to avoid restrictions - such as a hosepipe ban - being brought in.
The desalination plant, which converts sea water into fresh water, was brought into use on 23 July .
It has already added an extra 100 million litres into the island's supply - enough to fill Millbrook reservoir three times over.
The plant costs more than £5,000 a day to run.
Jersey Water says, with no rainfall recorded yet in August and streams beginning to dry up, water levels are 5% below average.
Mark Bowden, Head of Water Resilience, says we currently have enough water reserves for up to 85 days.
But with temperatures forecast to rise in the coming days, he's expecting demand from islanders for water to also increase:
"Our message is still for customers to only use what they need and cut back on any waste. We’re encouraged to see demand falling and appreciate the efforts people are making to reduce their use. Thanks to this, we’ve so far been able to avoid introducing any restrictions.”
Jersey Water says there are no plans as yet to bring in temporary use bans, but it is closely monitoring demand.
