Ireland’s data centres consumed a significant amount of water during the unusually hot and dry summer months, with usage exceeding 514 million litres between May and July. This represents a near doubling of typical consumption, raising concerns about the sustainability of these facilities. The increased water demand occurred despite, and even during, the implementation of hosepipe bans for the general public, highlighting a disparity in water access. While data centres are vital for the digital economy, their substantial water footprint is under scrutiny as Ireland faces increasing climate challenges. Authorities are now examining the situation to determine if regulations are sufficient to manage water resources effectively. The surge in usage prompts questions about the long-term impact of data centre expansion on Ireland's water supply and infrastructure. Further investigation will likely focus on water conservation strategies within the data centre industry.
