Where Does Drinking Water Come From on a Cruise Ship?

By Robert Palmer

Cruise ships are well-known for their luxurious amenities, but one of the most important features is often overlooked: the drinking water. Cruise ships use a variety of methods to provide passengers with potable water, ranging from desalination to recycling.

Desalination is one of the most common methods used on cruise ships. The process involves taking seawater and removing the salt and other minerals from it, leaving behind pure drinking water.

This type of system is usually found on larger vessels and works by pumping seawater into a reverse osmosis device, which filters out the salt and other impurities. The fresh water is then stored in tanks until it’s needed.

Recycling is another method used on cruise ships to provide passengers with drinking water. In this process, wastewater from sinks, showers, and toilets is treated and filtered before being recycled back into the ship’s drinking water supply. This type of system requires regular maintenance to ensure that all impurities are removed before the recycled water can be consumed by passengers.

Water Filtration systems are also used on cruise ships to remove impurities from the onboard supply of tap water. This type of system uses a series of filters to remove chlorine and other chemicals that could be harmful if ingested. The filtered water is then stored in tanks and dispensed through taps throughout the ship for passengers to use for drinking or cooking purposes.

Conclusion: Cruise ships use a variety of methods to ensure their passengers have access to safe drinking water during their voyage. Desalination, recycling and filtration systems help keep these vessels supplied with potable water no matter where they travel.
