Water Supply on Cruise ships

  1. Mar 27, 2012 #1
    Do cruise ships store clean water aboard in tanks or do they use desalination systems? Or do they take on water from their destination ports?
    I did a search online and I couldn't find any reliable sources.

    Is it any different on an ocean liner?

    Navy ships make water using RO machines or distilling but top off their water tanks in port with city water. I can't imagine cruise ships would do any different.

    They use flash evaporators or reverse osmosis, but I would imagine that they keep a large quantity on hand and/or fill it from a municipal source whenever possible for cost reasons.

    Thanks for the responses!

    Could anyone of you give me references/articles about water treatment onboard cruise ships or ocean liners? That would be greatly appreciated!

    You can find out how it's done on the Queen Mary 2 by looking on Wikipedia:

    (are there any other ocean liners in regular passenger service nowadays?)

    Thank you! I assume it'll be the same on cruise ships by Carnival, Royal Carribean, Norwegian
