Irish Water's data centre water usage figures contradicted by Meta's own reporting
By
Lois Kapila
Summary
This investigative article examines the discrepancy between Irish Water's reported figure of 810 megalitres of water consumed annually by data centres in Ireland (as of 2021) and Meta's own reported withdrawal of 928 megalitres for its Clonee data centres alone that same year. The gap raises serious questions about data accuracy, transparency, and trust. While much of the debate around data centres has focused on electricity consumption, their water usage is drawing increasing scrutiny. Irish Water has been unable or unwilling to explain its methodology behind the 810 megalitres figure, fueling concerns about whether regulators truly understand the resource demands of the growing data centre industry in Ireland.
