> It's unlikely an urban fire department is set up for any significant amount of drafting (pulling water from surface sources), if it's something they can do at all.
London Fire Brigade for example has nine special pumps that can draw 2000 gallons a minute each from river or lake supplies. So that's 18,000 gallons a minute just from them.
Yeah, but that's not "a significant amount". It's certainly less than half of what you would need to fight this fire head on. That's also assuming all those engines are in-service, staffed, and can get there and get set up within a reasonable amount of time.
