Albanese government proposal to state environment ministers would require new data centres to use recycled water and fund the infrastructure to deliver it, shifting the cost off household bills.
Australia's federal government is preparing to bar new data centres from drawing large volumes of drinking water for cooling, and to require them to underwrite the public infrastructure needed to deliver recycled supply instead.
The Albanese government proposal goes to state environment ministers on Friday. It would require new data centres to prioritise recycled water and to pay for any new public water infrastructure required to meet their demand. The government has framed the policy as protection for household supplies and a limit on the impact of new data centre demand on water bills.
Wire coverage of the rule will read as a ban. The substance is a cost-allocation decision: data centres can still build, but the cost of the water and the pipes to deliver it has to land in operator budgets, not on the household rate base. According to the ABC's federal politics live blog in July, the water rule sits alongside a parallel power-underwriting expectation under which new data centres would be asked to bring their own generation or grid-supporting capacity rather than rely on household-funded network expansion.
The federal government already published an "Expectations of Data Centres and AI Infrastructure Developers" framework through the Department of Industry, Science and Resources. A joint media release from Climate Change and Energy Minister Chris Bowen and Industry Minister Tim Ayres framed the framework as an "Australian approach to AI" that gives developers a national policy signal ahead of state-level planning decisions. The water rules extend that framework by adding a binding recycled-water-first requirement and a developer-contribution model for new public water assets.
The proposal is not yet law. It will be presented to state and territory environment ministers on Friday, a national-to-state hand-off through the environment ministers' council. Until those ministers adopt consistent language, the rule sits as federal policy intent layered on top of state planning and water-allocation regimes. The ACT, New South Wales, Victoria and Western Australia have all been fielding data centre proposals over the past 18 months, and the water question has surfaced in each jurisdiction's planning process.
New South Wales is already running a parallel state-level Data Centre Consultation Paper that asks operators about water sourcing, recycled supply, and the cost of any new public assets. The federal proposal does not displace that consultation; it sets a national expectation that state planning regimes can be measured against.
The Water Services Association of Australia published a sector report in December 2025 on data centres and water use, providing the first industry-wide baseline for an Australian conversation that has, until now, mostly played out project by project. SBS News has reported that data centre operators could "cut corners" on the new expectations framework, particularly on energy and water reporting, if the rules are not enforced with teeth at the state level.
Friday is the first milestone. The next test is whether state planning regimes adopt the recycled-water-first language, and whether a major data centre proposal applies the rule to a specific site. The federal Expectations framework is the policy bookend; the state consultation papers are where the mechanism actually bites.
