How does the Sewage System of an Aircraft work? Do they have a tank for storage and someone is going to deal with it after landing, or do they simply dispose it into the Air?
I suppose the first one makes a bit more sense and is a lot more hygienic.........

Toilet water is stored in a tank. Except airbus planes. These planes use technologically advanced systems that sanitize the water and extrapolate the... waste. The water is then sent to sinks and galleys for use in food preparation.
Just kidding.
Toilet water- Airbus Boeing Douglas or anyone else- is stored in a tank. Other water, like that used in sinks and galleys, is piped down and out the tail end of the aircraft. It's supposedly a booger when the coffee clogs up the pipes, as it smells and you can't use the sinks.
But next time you are in an airplane, wash your hands and listen when you push the sink drain- the whoosh is the air going by the drain and sucking out the water several yards away.

Toilet waste in any larger a/c´s is stored in one or several waste tanks,upon landing the tanks are drained of waste by a toliet service vehicle,toilet fluid are then first of used to rinse the system of any and all remains of waste...then a certain amount of fluid is filled in the tank to kill of smell&germs...(and to help you flush the damn thing)
Older a/c´s have as many as four different waste tanks(with x-amount of toilets hooked up to them),whilst newer ones only have one central tank serviceable from one location on the fuselage.
Today a 737NG or any newer Airbus takes no time at all to conduct toilet service on...whilst a L-1011 or a DC10 takes ages litterarly....during winter season it´s no fun havin´the toilet detail...everythin´s frozen solid....)
Fresh water´s stored in separate tanks,and when used for washing your hands,brewing coffee or whatever,it´s disposed through drain masts on the fuselage.

An aircraft with lavatories has sewerage tanks to collect the waste. The aicraft's tanks are usually emptied after a flight or for aircraft such as 737s flying domestic services all day it will be emptied at the last port of call where the aircraft will sit for the night. On the 737 there are some valves located in a door just forward of the forward cargo hold door. It has a valve for emptying the waste and another where a hose is connected to flush the system. I was only shown this over the last week so If I have any information that is incorrect please feel free to do so.

Lavatory service panels are located as follows:
-DC-9&MD-80:one on the left side of the fuselage just below&behind door one,and one under the left engine.
-B-737/1-400:one on the right side of the fuselage between&below the flightdeck and right side cabin service door+one directly at the bottom of the fuselage behind aft cargodoor(adj.to water service panel).
B-737NG:one on the left hand side,rear end of fuselage under aft left hand side cabin door.
B-757:one on the bottom of the fuselage left hand side just behind the nosegear(adj.to ground power access)+one on the bottom of the fuselage between the main landing gears.
B-767:one directly on the bottom of the fuselage in the rear.
A-320: one on the rear end,bottom left side of the fuselage.
A-330:one on the rear end bottom left side of the fuselage to the rear of the water service panel.
Could list more than a dozen more,but someone else might do that instead.
What you call "blue ice",is infact lav.service fluid that has leaked out from the lav.drain valve and turned into ice in flight.
If the drain valve leaks,blue colored ice gathers within the service panel,thus making it more difficult to conduct a fast toilet service.

Well, I'm not quite sure if this is exactly the same, but it comes close (at least I think) in terms of toilets. On the Morrison-Knudsen sleeper train cars, the retention toilet keeps a -14 PSI pressure in the main tank (God help you if a pressure switch gets obstructed - it'll never flush, even when there is sufficient negative pressure). When you "flush", it's really the vacuum pressure removing the waste rather than the water pushing it (like in a home toilet). At designated stations, a "honey truck" (laugh if you may, that's the name they give it) removes the waste from the tank and adds degerm to the degerm tanks. Potable water is kept separate from the toilet systems and is allowed to drain onto the tracks (coffee, kitchen water, lavatory water, etc.) Not quite aviation, I'm sure, but that's where they got these systems from in the first place.

Thanx for that info...always wondered how them train´s solved the waste issue...now I know...
Seriously,I thought that they just dropped it on the tracks,except when parked at a station.
Here in Sweden all railcars used to do just that up until a few years ago...hence why a visit to the can whilst beeing parked at a station,was prohibited and subjected to heavy fines.

"Honey Truck." Although funny, I think that's what they used to call the guy that had to dump out the waste in the mine shafts- the "Honey Dipper."

we call the truck either the " poopdeville" , the "crapillac" or a "turdhearse" and the guys that run it are the SWAT team members ( Sewage-Waste-And-Trash )

The Biffy truck
On the old Ford Trimotors you didn't need one. The can was a hollow tube open to the outside with a seat on it. You got a nice view of the world passing you by before you sit down...
But that ice cold draft made sure that you didn't stay long.
