Aircraft toilets always sound pretty damn loud to me. And their main reason to exist on planes is the lack of available water. Pretty sure that is not an aircra

  Actually ships are very water constrained. Especially Nuclear as they can't risk sea water contamination to the reactor cooling.

    Modern aircraft carriers have reverse-osmosis desalination systems on board. These can supply hundreds (thousands?) of tons of potable water per day.

      Thank you for this information, for I was wondering why they wouldn't have desalinization technology on-board, and you've answered the question -- they do. Thus, I don't understand the lack of fresh water.

    Yes, fresh water is a valuable commodity at sea; on U.S. Navy ships, water-flushed toilets are flushed with sea water, not fresh — or at least that's the way it used to be, and I can't imagine it'd be different today. (Source: Three years' sea duty as an engineering officer in the aircraft carrier USS Enterprise, CVN-65.) EDIT: See https://www.navy.mil/submit/display.asp?story_id=103122 https://www.navy.mil/submit/display.asp?story_id=103122 for a 2017 press release describing how the Reactor Department produces fresh water aboard the aircraft carrier USS Abraham Lincoln (a Nimitz-class carrier, i.e., an old design). TL;DR: It's done with giant evaporators, that is, distilling units. Fun fact: At sea, one of the big uses of fresh water aboard a carrier is the repeated washing down of the aircraft to reduce corrosion from the salt air.
