Here's the most sensible post I've seen about Beech and the broken water main. This is from a DCSki member who doesn't ski in NC but has experience with snowmaking in the mid-Atlantic.
"A broken main has to drain out. I don't know how Beech is set up, but I've worked snowmaking systems with buried pipe that just didn't have a fast way to drain, and others where the drain wasn't easy to get to quickly (IE dirt road to a remote pump station). Getting the pumps shut off in a couple minutes and the system drained in 20 minutes - most of the water coming out was likely from head pressure, not pumped - is about normal for a panic stop. As for the lift, what I hear is the water tripped brittle bars/sensors on the tower. That stops the lift and has to be bypassed by a mechanic going into the panel. That explains one of the two stops. What I don't exactly understand is why the lift stopped, started, and stopped again.
Stowe had a similar but potentially worse failure that happened to be visible from the base of their gondola a few years ago, but it happened to hit empty cabins."
