‘Not sustainable’: Aus city running out of water as population growth, data centres push supply to the brink

One Aussie city is desperate for water as a drier climate, a growing population and a boom in data centres all threaten to use up its dwindling supply.

  • Approved data centres add 2% to Sydney's water demand

  • Centres seen taking up to a quarter of city water supply by 2035

  • State has approved all 10 data centres it has ruled on

  • Most approved centres gave no numeric water reduction plans

SYDNEY, Sept 15 (Reuters) - Authorities in Sydney approved construction of data centres without requiring measurable plans to cut water use, raising concerns the sector's rapid growth will leave residents competing for the resource.

The New South Wales state government, which presides over Australia's biggest city, green-lit all 10 data centre applications it has ruled on since expanding its planning powers in 2021, from owners like Microsoft (MSFT.O), Amazon (AMZN.O) and Blackstone's (BX.N) AirTrunk, ALL building tremendous high volume water uses.

AWG WATER IS THE ONLY WAY. HOUSEHOLDS & BUSINESS MUST GET PREPARED.
