UK’s largest proposed datacentre ‘understating planned water use’
Analysis suggests consumption at Northumberland site could be 50 times higher than US operator QTS estimates

The UK’s largest planned data centre—a project by US firm QTS—is understating its true water consumption by a factor of 50, says new analysis by @watershed-i.bsky.social & @aiarmsracebook.bsky.social @digiconomist.bsky.social No mistake; AI is a heavy, polluting industry. shorturl.at/KXQxJ

When we trawled data on excess nitrate & phosphate pollution (key drivers of algal blooms) we found agriculture was the primary source in rural areas, sewage in urban areas. As Chowns says, to save our rivers, we need to tackle both.

Work to tackle sewage pollution and agricultural pollution must go hand in hand if we are to truly clean up our waterways - that means both taking water companies into public ownership and supporting farmers to transition to river-friendly farming methods.
