Where do cruise ships dump their waste?


Where do cruise ships dump their waste? U.S. law requires cruise ships to treat waste within about 3.5 miles of shore—but beyond that, there are no restrictions on dumping polluted sewage and graywater. Researchers have estimated that over a billion gallons of sludge made from excrement and food scraps are released into the ocean every year by cruise lines.


Where does all the sewage go on a cruise ship?

Do Cruise Ships Dump Sewage? Yes. To get into a few more specifics than above, the U.S. allows cruise ships to dump treated waste into the ocean if they are within three and a half miles from shore.

The easiest way for ships to do this is to liquefy the leftover food in an industrial grinder.

Simple as that.


Why do cruise ships drain the pools at night?

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.


Do cruise ships pollute more than airplanes?
