Water is used mostly for cooling. It’s pumped in and then pumped back out as is, only a few degrees warmer.
Because of environmental regulations reactors are forbidden from rejecting hot water during heatwaves, when the extra heat would get water above a temperature threshold that’s dangerous for wildlife (ie fishes). But it’s typically not a lack of water.
Newer reactors are designed to be cooled by other methods such as, IIRC, liquid metal. Water-cooled reactors were, again IIRC, originally designed for nuclear submarines. Watch the documentary if you have an hour to kill, it’s really interesting!
Current reactors also use huge amounts of water which many places don’t have (France for example).

Yes, that’s what I meant to say.
