"A report into commercial datacentres' water usage in England suggests the sector is more efficient and less water-intensive than previously thought, thanks to advances in cooling technologies. The survey, carried out by UK tech trade body TechUK in collaboration with the Environment Agency, set out to assess the environmental resources consumed by the datacentre industry in England, with a particular focus on water use. TechUK gathered data from 73 sites across England, including more than 50 in the Water Resource South East region, and its findings showed that modern cooling systems are less reliant on potable water to keep servers from overheating than perhaps thought."
"According to the results, 51% of surveyed sites use waterless cooling systems that require no additional water beyond the standard use of a commercial building. Out of those facilities that do use water, most employ hybrid systems combining air, water and refrigerant-based heat rejection, with only 5% relying entirely on water-based cooling."
A survey of 73 datacentre sites across England found that modern cooling technologies have substantially reduced reliance on potable water. Fifty-one percent of sites use waterless cooling that requires no additional water beyond typical commercial building use. Most sites that do use water employ hybrid cooling combining air, water and refrigerant-based heat rejection, while only 5% rely entirely on water-based cooling. Datacentres account for a small fraction of broader industrial water consumption, with 64% of sites using annual water volumes comparable to a Premier League football club. Liquid and direct-to-chip cooling are driving ongoing water-efficiency gains.
