The waste and blue cleaning fluid ends up in a storage tank under the floor, in the very back of the cargo hold of the aeroplane. With so many people on the plane using the toilets, you can imagine how big the storage tank is!
The name comes from the blue color of the disinfectant. Airlines are not allowed to dump their waste tanks mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur from a plane's septic tank.
When one flushes the toilet, the waste is sucked out by the vacuum, and placed into a large holding tank. While the vacuum system in use is loud, it is nothing to be afraid of. Waste is sucked out with the power of what experts said, is a velocity faster than that of a Formula 1 race car.
Answer: all the sewage is collected in tank and disposed when the plane lands. Waste water created in flight is stored in a holding tank on the aircraft until the plane sets down. When it's on the ground, a service truck rolls up and pumps the contents of the plane's holding tank aboard.
Chemical holding tanks (retention tanks) are usually included on newer carriages and railcars in wealthier and more densely populated parts of the world. One issue is that the tanks need to be regularly emptied, often at a terminal station or prolonged stop-over.
Did you know the UK still has hundreds of trains that dump poo onto the train tracks? It's thought that one in every ten trains still doesn't have a tank on board to store the waste. People that live near the railway are left with a stinky situation and there are even health concerns.
Most boats have holding tanks, which can be pumped into an on-shore facility, and some have a Y-shaped valve with the ability to either store waste or directly release the contents of the holding tank into surrounding water.
The truck plugs a hose into the airplane's waste tank valve and removes all of the waste into the tank on the back of the truck. The truck then takes the waste to a special area at the airport reserved for the waste from all aeroplanes, and the toilet waste is emptied into the sewer system for that airport.
“Treated” sewage can be discharged overboard as long as the ship is 3 miles or more from shore. Untreated sewage can be discharged overboard as long as the ship is 12 miles or more from shore.
Waste tanks – where everything that goes down the toilet ends up – are usually located at the back of the plane, and often at the front, too.
"There isn't any danger of flushing the toilet while a passenger is sitting on it because it is tested that way," Daniel Bubb, an aviation historian and associate professor in residence at the University of Nevada, Las Vegas Honors College, stated.
Key Takeaways. Airplanes may need to dump fuel before landing to reduce weight in emergencies or due to maintenance issues. Not all aircraft are equipped with fuel-dumping systems; typically, only larger, wide-body planes have this capability, as required by the FAA.
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.
Can cruise ships dump waste at sea? Yes. It's quite legal to dump sewage and food waste into the sea. 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.
A United Airlines flight from San Francisco to Boston had to make an emergency landing in Denver after the aircraft's wing began to disintegrate mid-air. Terrified passengers witnessed the harrowing scene as the plane struggled with its broken wing.
Some will leave it a mess, and the cabin crew has to make sure these are clean for the next passenger to use. Hence, if flight attendants have to tidy up a lavatory if they see it dirty and in disarray, yes, they have to clean it. This is the case for most airlines.
It is a common misconception that toilet waste from commercial aircraft falls out of the aircraft in flight; this is not the case. Modern airplane toilets are designed with a closed and sealed waste containment system to ensure that waste is securely stored until it can be properly emptied on the ground.
Hazardous waste generated onboard cruise ships are stored onboard until the wastes can be offloaded for recycling or disposal in accordance with RCRA. A range of activities on board cruise ships generate hazardous wastes and toxic substances that would ordinarily be presumed to be subject to RCRA.
Amtrak presently is permitted to dump untreated waste from passenger train toilets and washing facilities directly onto the track. Older cars (predating Amtrak's formation in 1970) have no capability to retain waste.
Treated sewage passes through a Type I or Type II Marine Sanitation Devise, or MSD. Depending on the boat set up, the treated waste is then stored in a Type III MSD (holding tank) or discharged directly overboard. Untreated boat sewage may be stored in a Type III MSD or discharge directly overboard.
“The sewage produced on board the ship cannot be held on the ship for an extended time. For this reason it must be discharged into the sea.”
