Lake interconnect inspections

In preparation for the upcoming Bobcat project, we have identified a number of corrugated metal pipe (CMP) lake interconnects that have begun to fail.  The galvanized metal is 30+ years old in most cases, and has outlived its effective lifespan.  The most cost effective way to replace these pipes is to dig them up and lay new high density polyethylene (HDPE) pipe in their place.  However, some areas don't lend themselves to excavation and construction work, so the company Extreme Divers has a patented system for installing sleeves inside existing CMP pipe, eliminating the need to dig them up.  Extreme Divers has been on site at The Forest for the past few weeks inspecting the candidates for sleeves with their remote operated vehicle equipped with a video camera mounted.  Very interesting stuff!
