I noticed that at most airports there is a large hose attached to the jetways now that hook up to the plane itself when at the gate. The hose is from the bottom of the jetway and then extends outward to meet part of the plane, where its attached.
It is obviously one of the many utilities provided to the airplanes, but which one as you have fuel (I think not here), sanitary disposal, electricity, or maybe water. Does anyone know which one of these that is used in that conduit?

I think that it is ground power, or computer connection. Fuel is hauled to it via truck (i used to do that job in the military, civilian version is not too different) water is done just like the crap truck, via a vehicle coming out and hooking into it.
The big hose under the jet bridge is usually HVAC. Power and comms are a cable, fuel is from a truck or from a hose connected to the ground opposite the jet bridge (for bigger airports with fuel pipes to each gate), and waste is sucked into a truck that connects under the plane. If you're talking hose and not cable, you're probably talking about the HVAC.
For some reason, I was always of the impression that waste was merely jettisoned from the plane, and broke up in the atmosphere before reaching the ground.

That is how it used to be done on trains...and people thought that is how planes do it.

Sometimes it doesn't break up. There have been reports of sludgsicles falling through people's roofs. Lime green sludge. You can guess what it's made of.
