I lived in NYC for well over a decade and I never knew this existed! This is so cool. I wonder why it was limited to Roosevelt Island, the system is so futuristic and clean. Maybe it costs a ton of money? It seems like it should save money in sanitation staff over the long run assuming it's not too hard to interconnect and keep the pressure up for new buildings.
