Arguments about water "consumption" (hint: it's still water afterwards - it tends to clean itself if you didn't outright poison it and wait a bit) do not apply in humid regions - saving water someplace else doesn't help regions with water scarcity one bit. Berlin is an extreme example, they need to pump water out of the ground in any case to prevent the area from reverting to a bog.

Hot water usually costs a lot of valuable energy though.

The world is going to have more, not fewer, dry regions where water must be conserved over time.
