For desalination, the important part is paying the ongoing cost. The opex is much higher, and it's not fair to just average that into the supply for everyone to pay.

Are any data centers using desalinated water? I thought that was a shockingly expensive and hence very rare process.
(I asked ChatGPT and it said that some of the Gulf state data centers do.)
They do use treated (aka drinking) water, but that's a relatively inexpensive process which should be easily covered by the extra cash they shovel into their water systems on an annual basis.

Read the comment I replied to, they proposed that since desalination is possible, there can be no meaningful shortage of water.
And yes, many places have plenty of water. After some Capex improvements to the local system, a datacenter is often net-helpful, as they spread the fixed cost of the water system cost out over more gallons delivered.
But many places don't have lots of water to spare.
