Cruise ships have continued to gain popularity over the years because of the unique manner that they conduct business and pleasure. The one-of-a-kind manner of entertaining people on board cruise ships has become a statement that lured many people to spend their holidays aboard such ships. Furthermore, certain cruise ships have been designed as hospitality centers fully-equipped with hospital amenities and fully-operational mortuary, solely catering to the terminally-ill individuals who preferred to be on a cruise ship and wait for their destiny rather than be confined on hospital beds.
Given the situation on a ship plying the abundance of the ocean where the ocean's salty breeze causes one to suffer from dehydration, drinking water as well as water for bathing is always in demand. Water is very vital to human survival. A person can last about a month without food but not a week without water to drink. Furthermore, water is essential in maintaining hygiene and in accomplishing activities of daily living. With the large-scale number of passengers and crew on a cruise ship, goes with the need of a reliable water supply 24/7 anywhere on the ship. Drinking water may not pose a huge problem but water for bathroom, bathing and ship's kitchen activities: food preparation, restaurants use, etc. certainly is another issue.
Where and how do cruise ships get their water supply? Today, cruise ships or any ship for that matter have been built with water treatment facilities or ocean-water desalination plant. Desalination, the removal of salt and other impurities from sea-water so that water can become safe for human consumption, has been practiced hundreds of years back. However, technology paved way for its improvement and perfection such that desalinated ocean-water today is safe for drinking although in the United States, only less than 1 percent benefit from it. Middle East, specifically Saudi Arabia, where oil is abundant underground instead of water, has been supplying about 70 percent of desalinated water to its people while Australia uses it as supplemental to the existing supply.
Because of the desalination process, passenger ships need not be loaded with hundreds of tons of water into its concessions as ocean-water can be distilled, travel into pipelines and into every cabin's water system. In fact water-saving device such as showers and faucets have been specifically designed to allow only for the minimal water consumption of passengers such that waste is minimized however not sacrificing their satisfaction. Moreover, the ship's crew are relieved of the fear of having the ship overloaded thereby putting every passengers' life at stake.
The sanitation system through the shower and drainage system of ships especially that of passenger and cruise ships must provide full satisfaction to passengers and make them feel that they are in a hotel for a holiday and need not feel that they are out in the dessert or outback where water and comfort is scarce.
