Scottish data centres powering AI already using enough water to fill 27 million bottles a year

In a striking development for Scotland’s tech landscape, new figures reveal that the volume of tap water consumed by data centres has surged fourfold since 2021. This significant increase raises important questions about the sustainability and environmental impact of the growing data centre industry in the region. As the demand for cloud computing and digital services continues to escalate, data centres—facilities that house computer systems and associated components—are becoming vital to supporting the digital economy. However, their rising water consumption highlights a pressing need for responsible resource management and innovative solutions to mitigate environmental concerns.

The data centres, which are essential for processing and storing vast amounts of data, require substantial cooling systems to maintain optimal operating temperatures. Traditionally, this cooling has relied heavily on water, leading to the quadrupling of tap water use in just two years. For instance, in 2021, the water consumption was recorded at approximately 1.5 million cubic meters, but by 2023, that figure has soared to roughly 6 million cubic meters. This trend poses a significant challenge for local water resources, particularly in light of Scotland’s commitment to sustainable development and environmental stewardship. The rise in water usage coincides with a broader expansion of the tech industry in Scotland, which has seen numerous data centres being established to cater to the increasing digital demands of businesses and consumers alike.

As the industry continues to grow, stakeholders are urged to consider alternative cooling methods, such as using renewable energy sources or innovative cooling technologies that minimize water usage. Furthermore, the Scottish government and environmental organizations are calling for comprehensive assessments to understand the long-term implications of this water consumption trend. Balancing the needs of a burgeoning digital economy with environmental sustainability will be crucial for Scotland as it navigates the complexities of modern technological advancements. Addressing these challenges head-on is essential not only for preserving local ecosystems but also for ensuring that Scotland remains a competitive player in the global tech arena.
