High-tech data hubs across Ireland are drawing renewed public criticism as new figures reveal they consume nearly five million litres of public drinking water every day. The disclosure coincides with a strict six-week hosepipe ban implemented to safeguard shrinking water reserves during an ongoing national heatwave.
Rising Tensions Over Resources
The newly enacted restrictions apply to residential, agricultural, and commercial users across Dublin, south Tipperary, and portions of Kildare, Meath, Wexford, and Wicklow. Under the mandate, individuals must cease non-essential water activities until late August.
The limitations have sparked political debate regarding the state's resource management. Opposition TD Ciarán Ahern criticized the administration, noting that an average individual uses about 133 litres daily, while just 57 data facilities consume a combined average of 4.78 million litres each day. He condemned the government's approach as "cognitive dissonance" given the rapid expansion of the sector.
In contrast, Taoiseach Micheál Martin dismissed comparisons between household restrictions and commercial data usage, arguing that evaluating the two side-by-side is not a valid correlation.
Regional Strain
The conflict is most pronounced in the Greater Dublin Area, where the bulk of the nation's digital infrastructure is concentrated. In this region alone, data centre demand pushes past five million litres per day.
The surge comes at a delicate time for the utility provider, Uisce Éireann, which recently recorded an all-time daily peak of 693 million litres supplied to the Greater Dublin region. Officials stated that the unprecedented demand—driven primarily by domestic outdoor tasks like power-hosing and gardening—is placing severe strain on the distribution grid.
Utility Defends Tech Footprint
Uisce Éireann has downplayed the impact of tech infrastructure on the broader system. The utility provider noted that it generates over 1.7 billion litres of clean drinking water daily, meaning data hubs account for less than 1% of total national production.
A spokesperson for the company explained that out of roughly 100 operational facilities in Ireland, only 57 campuses spread across Dublin, Meath, Cork, and Louth rely on the public system. They emphasized that modern cooling technologies allow these facilities to operate on relatively small volumes, representing just 0.3% of the network's total output.
While the state utility maintains that data centres are not the primary driver of the current supply strain, political pressure continues to mount as citizens face restrictions during the prolonged dry spell.
