Put simply, when you flush the loo, the sewage goes straight to the on-board treatment plant which treats it until it’s drinkable and then pumped back into the ocean, far away from land.
What happens to all the sewage on a cruise ship?
Sanitary wastewater on ships is divided into ‘black water’ (sewage) which is anything flushed in toilets; and ‘grey water’ collected from bathroom sinks and showers, laundry, and galleys (kitchens). This leaves clean, safe and bacteria-free water, which is transferred to a storage tank until it can be discharged.
Do cruise ships have holding tanks for sewage?
Wastewater is run through the advanced wastewater-purification plant on the ship, which is above the US federal standard for purified water. This leaves clean, safe and bacteria-free water, which is transferred to a storage tank until it can be discharged.
How much waste do cruise ships dump in the ocean?

What is the poop cruise?
While at sea with over 4,200 passengers in February 2013, the ship lost power due to a fire in the engine room, leaving the ship adrift off the coast of Mexico. Passengers later reported sewage backing up onto the floors, leading the media to dub the voyage “the poop cruise.”
How do boats dispose of human waste?
Most commonly, yachts will follow the same tactic as other ocean-faring vessels, in that they discharge waste directly into the oceans. Many of the modern vessels have holding tanks for human waste (black water), but wastewater (gray water) is usually evacuated into the ocean itself.
Do cruise ships have jails?
Cruise ships do have jails. Called the brig, they are rarely used, but when they are, it is generally for those passengers who commit serious crimes where criminal prosecution is likely, such as drug trafficking. Most guests on a cruise ship will never see the brig or have reason to visit.
Where does human waste go after a sewage treatment plant?
The treated wastewater is released into local waterways where it’s used again for any number of purposes, such as supplying drinking water, irrigating crops, and sustaining aquatic life.
Where does all the poop go?
The toilet flushes the wastes down the sewer pipe. The sewer pipe from your house also collects and removes other wastes. This might be soapy water from baths and showers, or water left over from washing dishes and clothes. Together, all of these wastes are called “sewage”.
What are the negative effects of cruise ships?
Cruise companies and cruise ships negatively impact communities through air and water pollution, economic leakage and tax avoidance, as well as overtourism. Such negative impacts can arise where cruise companies are based, where they pass through, and where they dock.
What do cruise ships do with food waste?
While at sea, food waste is stored and sorted separately from non-perishable materials. Most of this waste is then pulverised or pureed into fish food. The disposal can only take place while at sea and well away from coastlines or sensitive marine environments.
Are cruise ships safe in rough seas?
Yes, cruise ships are designed to handle rough seas. During rough seas, the captain may order passengers to stay indoors for the safety of everyone on the ship and for passengers with mobility issues, staying seated is a good idea.
Cruise Resident Costs Not all ships allow full-time residents onboard, but many cruise lines make accommodations for seniors who want to become long-term passengers and remain on the same ship for months or even years at a time.
Typically, the Navy disposes of “blackwater” from latrines by pumping it into city sewer systems after docking. In the open ocean, warships pump the raw sewage into the ocean, a common practice by private vessels.
