The evaporators could never keep up with the demand for fresh water so

I'm surprised they didn't have reverse osmosis systems, wonder if that
has changed?


Don't know what they use now. Both of my sons spent time on larger,
more modern ships and according to them they never had lack of water or
rationing.

My only experience with reverse osmosis was with two smaller systems we
had at one of the houses in Florida. One was in the kitchen that
produced drinking water. Water was blah. The other was a somewhat
larger system near the hanger. It had a 5 gallon storage tank that I
used as a final rinse when washing the cars. The problem with both of
them was that it took forever to replenish the water when the tanks were
empty. Very slow process.

You had fresh water systems with no pressure pump. Salt water systems
require much higher pressure and can be engineered to provide just
about any flow rate. My wife and I get by just fine with about 20
gallons a day on average. How many crew on a destroyer?
