I'm ignorant but aren't oil pipelines much longer? They don't need to traverse mountain ranges but still. Either way i can't imagine such a project would be possible in an emergency time scale without the combined assistance of the US, Israel (desalination experts) and China. i know absolutely nothing about these things, so i don't know if it's even theoretically possible with their help.

Apparently the highest oil pipeline throughput (Druzhba) is 1.4 million barrels per day, which amounts to some 2000 liters per second. That would be 20 liters/person/day - kinda maybe enough to move the needle, but not quite. Building this sort of pipeline today is about $1-2M per km on flat land. I'm not aware of comparable pipelines in the mountains. Then, desalination requires energy, and Iran already faces blackouts here and there, there just isn't much spare capacity.

  I think on a similar scale would be the Chinese South–North Water Transfer Project , which has taken several decades to eventually move 44.8 cubic km of fresh water via canls/aqueducts etc through some mountanious terrain. Or the undground Great Man-Made River Project of Libya moving 6.5 million cubic meters over 2,820 km. Main issue ther though is the first is from already present freshwater sources and the latter from underground aquifers. With both having been done over multilpe decades to reach that capacity. Finding the water to move would be the main challenge, een though the Caspian is less saline than ocean water - there are probably water usage agreemets with the neighbourign countries preventing a massive undertaking of such size.

  > 2000 liters per second Some people will try to blame EVs for environmental damage when we have this monstrosity.

    EVs are charged to a degree by Russian natural gas fed by another pipeline (13% or EU gas now).
