Pearson Airport in Toronto seems to have a good set-up for de-icing. they have a de-icing pan adjacent to the runway, on a sort of by-pass from the main taxiway. The pan can take every size from a little piper prop job all the way up to an A380 (I guess) and can take three or four at a time.
Each aricraft is de-iced by two or more trucks controlled by the operators in a cabin on the spray boom. I understand that the pan has a separate drainage system which captures the run off of de-icing fluids. I don;t know if you can rececyle this or not or whether this is purely for environmental reasons.
It seems to keep the flow of aircraft moving without too much of a hold up, so I guess it must be both fairly flexible and pretty effective.
