Where Does Toilet Waste Go On Cruise Ships

According to 33 CFR 159 water vessels need to have a US Coast Guard-certified marine sanitation device.

Where does toilet waste go on cruise ships. The waste is stored for up to seven days at a time until the ship docks back in Miami where all the plastic aluminum paper and glass go to recycling partner facilities. Every traditional boat toilet therefore functions by flushing or dropping the waste from the bowl into some form of holding tank. Boycott until they discharge at port into a waste water treatment facility.

FOE also cites data from the Environmental Protection Agency EPA which shows an average cruise ship with 3000 passengers and crew produces about 21000 gallons of sewage a day enough to fill 10 backyard swimming pools in. You know what this is. Here the waste is filtered before it enters an aeration chamber.

Calvin Ungs answer is pretty complete in addition it could be interesting to know what happens to the rest of the wastegarbage. Waste disposal should be done at least 12 miles offshore. It is then sterilized using UV light and released into the ocean when clean enough to do so.

Cruise cabins typically have hair dryers that are in the drawer of the vanity in the main part of the cabin. The discharge of sewage into the sea is prohibited except when the ship has in operation an approved sewage treatment plant or when the ship is discharging comminuted and disinfected sewage using an approved system at a distance of more than three nautical miles from the nearest land. Next the mix of water is sent to bioreactors deep in the bowels of the ship.

Some new ships sailing in environmentally sensitive regions such as the Arctic and Antarctica have a single stream Advanced Wastewater Treatment system where. In reality such incidents such as this are rare. But these days cruise ships must follow very strict international maritime laws.

Cruise ships like Symphony have a designated waste and recycling center. Green brown and white. Then it goes into bio-reactors deep inside the ship.
