What happens to toilet water on a cruise ship?

When a toilet is flushed on a cruise ship, the sewage travels to the onboard treatment plant. Here the waste is filtered before it enters an aeration chamber. The aeration chamber cleans the waste. It is then sterilized using UV light and released into the ocean when clean enough to do so.

The wastewater passes through a multi-chambered sewage treatment plant where the net end result is water which is even safer than household drinking water! Obviously, cruise operators don't send it for drinking purposes. That would be immensely gross!

Most cruise ship water is desalinated sea water. The process usually involves steam evaporation -- essentially turning saltwater into distilled water. That water is then mineralized for flavor and chlorinated for extra safety. Other ships are fitted with a reverse-osmosis system for filtering and/or desalination.

Cruise lines drain their swimming pools at night to discourage guests from trying to enter the pool when it is closed. Draining the swimming pools each night also allows the cruise lines to replace the water with clean water and a drained swimming pool is safer if the weather is rough.

Shipboard potable water (drinking, bathing, whirlpools, etc.) either comes from a shoreside water treatment plant or is generated on board from seawater via Reverse Osmosis systems or Evaporators. Swimming pool water is typically seawater.

Cruise ship bathrooms in most cabins on mainstream cruise lines are only as large as they need to be in order to contain all the functional parts -- sink, toilet and shower with room to turn around. Cruise ship shower stalls can be narrow, sometimes with curtains that cling when wet.

Usually, this involves your cabin steward cleaning and sanitizing the bathroom, emptying trash bins, replacing towels, making the bed/beds, vacuuming as needed, refilling ice bins, washing and replacing glassware and a general tidying of the room.

The kitchens are extra enormous. A ship that carries 3,500 passengers uses 600 pounds of butter per day, 250,000 eggs per week, and 170,000 pounds of fresh fruits and vegetables per cruise. Naturally, there are more hands on deck in the kitchen too.

All of that waste is either processed via biodigesters or dehydrators, or offloaded on shore. Some of the company's ships have long had dehydrators, which squeeze the water from food waste and lighten the load that can be taken to landfills, compost sites or waste-to-energy facilities.

Cruise line companies design ships to have various storage areas for different food items ? fresh vegetables, dairy, different types of meat, canned items and even beverages. Each of these storage areas has different temperature settings linked to the food being kept within.
