It wasn’t long after repairs began on Flumes 9, 10, 11, & 13 that the approval came for installing the overland piping system – so the crews that weren’t helping install the pumps worked on repairs on Flume 15. Flume 15 was crucial for the emergency water delivery system since it would be used as the outlet area for the 10-inch overland pipe system, and was installed just ahead of Flume 13, where we had a steel flume section that had survived the fire. Located just past the steel flume was an automatic siphon, which would allow us to maintain a constant level of water for the pumps.
