from the engine ops manual 1.75 inch and 2.5 inch hoses are used for fire attack
3.5 inch hose is used for supply lines - maybe hydrant to engine or engine to engine or engine to tower ladder engines might have 6 inch ard suction hose also - which could be used to draft from a river or harbor - or cistern if they have any per the engine ops manual - the only mention of cisterns says that some sprinkler systems have a cistern as a backup water supply to the city water main so hey - nyc you listening? - fdny you listening? - go cistern! - go cistern! - go cistern! you could hire someone from tokyo or san francisco to help with cisterns - maybe - if manhattan is all bedrock - that could be a problem - but you could build an above ground cistern into the bottom floors of a highrise and no one would even know that it was there -- You received this message because you are subscribed to the Google Groups "massfire" group.
