Recycled water to cool Sydney data centre from 2027

Summarised from 2 outlets · Updated 29 Oct, 19:39 · Archive

A recycled water facility will supply up to 16 million litres daily to cool NextDC's S4 Sydney data centre from late 2027.

AquaNet has announced plans to expand its recycled water facility in Fairfield, in western Sydney, to supply NextDC's S4 Sydney data centre under construction in nearby Horsley Park. The new infrastructure would allow the facility to be cooled entirely with recycled water—up to 16 million litres a day—once it starts flowing in late 2027. Recycled water is created by treating water from sources such as sewerage or storm runoff so it can safely be reused.

S4 Sydney is the first major data centre in New South Wales to be cooled with recycled water. Kurt Dahl, head of AquaNet's parent company coNEXA, said he hoped the project would be a model for the rapidly growing industry, particularly in the data centre 'hotspot' of western Sydney. 'There's lots of wastewater in western Sydney,' Mr Dahl said. 'There's an opportunity to build a network that services half a dozen to a dozen really large data centres.'

Data centres use significant amounts of water to cool their servers. Sydney Water recently warned data centres could use as much as 250 megalitres a day in the city by 2035, with one already ranking among its top 20 users. Alternative cooling methods without water require between 20 and 40 per cent more electricity, according to construction technology expert M. Reza Hosseini.
