What happens to aircraft toilet waste?
The waste passes through the plumbing at the rear of the plane, where it is stored in sealed tanks, away from passengers, until the plane lands. When the plane lands, a “honey truck” siphons off the waste and dumps it into the airport’s underground sewer system.
Where does the pee go when you flush the toilet on an airplane?
Toilets on airliners use either a “closed drainage system”, which operates much like a common household toilet and discharges waste water into an on-board holding tank, or the “water disposal system vacuum sewage”, more modern, which sucks the sewage into the tank.
