How Much Water Does a Cruise Ship Use Per Day?

By Anna Duncan

Cruise ships are an increasingly popular way for people to travel and enjoy a vacation on the open seas. With so many people sailing on cruises every year, it’s important to consider the environmental impact of these large vessels.

One of the most important aspects of this is how much water cruise ships use on a daily basis.

Cruise ships are equipped with desalination plants that convert sea water into fresh water for drinking, cooking, and other uses. These plants can produce up to 400,000 gallons of fresh water per day, depending on the size and type of vessel.

This means that even a relatively small cruise ship can use an enormous amount of water each day, especially when you consider that many of these ships have several thousand passengers and crew members onboard at any given time.

In addition to using desalination plants to produce fresh water, cruise ships also have large freshwater tanks which are filled before they set sail. The amount of freshwater stored on board depends on the size and capacity of the ship, but typically ranges from 1-2 million gallons.

This allows cruise ships to stay at sea for weeks or even months without needing to return to port for supplies or fuel.

On top of all this freshwater usage, cruise ships also need a significant amount of additional water for cleaning purposes such as washing decks and laundry services. Some estimates suggest that a single cruise ship could use as much as 1 million gallons per week just for these activities alone!

Conclusion:

In total, it is estimated that a typical cruise ship uses anywhere from 1-4 million gallons of fresh water per day depending on its size and destination. This is an incredibly large amount when you consider how many people are onboard any given ship at any given time! It is clear that reducing our reliance on freshwater sources is essential in order to ensure sustainability in our oceans and seas in the years ahead.
