Killington's website says they have 88 miles of snowmaking pipe. *uneducated question alert* If they are replacing "...up to 2,000 feet of snowmaking pipe, including sections on Cascade and Great Eastern ", that would take...176+ years to replace all the pipe in the system once. It seems like there should be more than that getting replaced each year?
Interesting question. IIRC, life span of the pipe is roughly 30-40 years. You can look back on Killington's expansion history and do the math. For example, the pipes on lower Pipe Dream were installed in the mid-early 70's, and failed a few years ago. Similar for valley plunge. OTOH, pipes the vital main basin/snowdon and other areas have seen constant work already to keep them up to par, since those areas have had snowmaking since nearly the beginning 50 years ago.
I would think the next area that will need a major snowmaking overhaul (or have repeated problems) is Bear Mountain, since most of that was installed in the early 80's.
I doubt they are replacing entire runs of pipe in most cases. Just cutting out bad sections and replacing them.
You'd be amazed at the amount of old snowmaking junk floating around the mountain. Most surprising to me is the pipe and hydrants on old lower cascade, behind the net. Still haven't heard when that was closed off, but it was at least 15+ years ago.
