While Selangor officials assert that data centre water usage does not strain domestic supplies, some stakeholders urge caution, highlighting potential risks in the context of rapid development and climate uncertainty. Data centres do use water predominantly for cooling, and cumulative expansion of these facilities could incrementally increase demand, especially in hot periods or drought scenarios.
Critics point out that official assessments may underestimate future pressures, given urban population growth, industrial demands, and possible variability in rainfall patterns affecting reservoir levels. Even marginal increases in water consumption by large-scale data centres might exacerbate supply challenges for local communities if not proactively managed.
There are calls for enhanced transparency in reporting water usage data and for stricter environmental impact assessments before approving new projects. Some advocate for prioritizing water conservation measures and exploring alternative cooling technologies that do not rely heavily on water.
Ultimately, skepticism remains about whether current policies sufficiently protect domestic water availability against the cumulative effects of emerging digital infrastructure. Vigilant oversight and contingency planning are essential to ensure that Selangor’s ambition as a tech hub does not compromise the fundamental needs of its population.
