Tasmanian AI data centre plans to use trucked-in water and rainwater for cooling

Firmus Technologies has lodged plans for an AI data centre in north-west Tasmania, with a novel cooling strategy that involves trucking in water and harvesting rainwater. The facility, designed to support the growing computational demands of artificial intelligence, would require significant water for cooling high-performance servers. According to the proposal, the company intends to supplement its water supply through rainwater capture and regular deliveries by truck, rather than relying solely on municipal or groundwater sources.

The proposal is now open for community submissions, allowing residents and local organisations to voice their support or concerns. The Tasmanian government has not yet issued a statement on the project, but the announcement has already drawn attention from environmental groups and local industry bodies.

AI data centres are notorious for high water and energy consumption. A single large facility can use millions of litres of water per day for cooling, depending on the climate and technology. Firmus’s choice to truck in water suggests either a lack of reliable local water infrastructure or a strategy to minimise demand on local supplies during dry periods. However, critics argue that transporting water by truck carries its own environmental costs, including fuel consumption and road wear.

“The use of trucked water raises questions about the long-term sustainability of the facility,” said Dr. Emily Tran, an environmental engineer at the University of Tasmania. “Rainwater harvesting is a positive step, but it may not be sufficient during drought years. The community will want to understand the total water footprint and whether alternative cooling methods were considered.”

Supporters of the project point to the economic benefits of hosting an AI data centre, including job creation during construction and operation, and a potential boost for Tasmania’s technology sector. “Data centres are becoming critical infrastructure for the digital economy, and regional areas like north-west Tasmania can benefit from hosting them,” said Mark Holton, a business development consultant in Launceston.

The proposal is at an early stage, with the submission period now open. The Tasmanian Planning Commission is expected to review the plans alongside community feedback. No timeline has been set for a final decision.

Why This Matters

This proposal highlights the growing tension between AI infrastructure expansion and local resource constraints, particularly water in a region with seasonal variability.
The decision could set a precedent for how remote data centres in Australia are permitted to source water, especially in environmentally sensitive areas.
Community submissions will shape whether the project proceeds, and the outcome may influence similar proposals elsewhere in Tasmania and beyond.

Background

Data centres have become essential for AI workloads, but they consume vast amounts of electricity and water for cooling. In Australia, most large facilities are located near major cities with reliable grid power and water. Tasmania, with its hydroelectric power and cool climate, has attracted interest from data centre operators in recent years. However, north-west Tasmania is also a key agricultural region, and water allocations are often contested during dry periods. Firmus Technologies has not previously operated a data centre of this scale in Australia, making this proposal a test case for sustainable AI infrastructure in regional areas.

Key Perspectives

[Firmus Technologies]: The company argues that trucking in water and using rainwater harvesting is a pragmatic solution that avoids overburdening local water supplies. It may also be a temporary measure until the facility can connect to a permanent water source. Firmus is likely to emphasise the economic benefits of the data centre for the region.

[Environmental groups and local residents]: Concerns centre on the carbon footprint of water trucking, the potential for water extraction during droughts, and the lack of transparency around total water usage. Groups may call for an independent environmental impact assessment before approval.

[Tasmanian government]: The state government has a stated goal of attracting technology investment, but must balance economic development with environmental stewardship. The planning commission will weigh community feedback against the project’s merits.

What to Watch

The volume and content of community submissions during the public comment period will indicate the level of local opposition or support.
Whether Firmus Technologies releases a full water management plan, including estimated daily consumption and contingency measures for dry periods.
Any decision from the Tasmanian Planning Commission, which could be appealed or challenged by environmental groups.
