Some facilities is do this. They’re not 100% efficient, so some is lost to evaporation, some must be dumped because it has too much mineral content (and too much conductivity) to go back through the cooling system. Reusing is only about 50% efficient (according to Google’s numbers).
There was a series on SyFy around 2015 called Dark Matter about a crew that wakes up on a spaceship with no memories. It was okay.
