Flume 15 remained partially intact, but still had some structural damage in regard to the foundation bent structures. Additionally, the flume had dropped about 2 feet in elevation, so it needed to be raised and repaired before the pumps for the overland pipe system became operational.

It was determined that it would take four 200 horsepower, high pressure pumps, with six-inch discharges to pump the 350-foot head of water. The engineers wanted to ensure that this system could continually carry water while the flume was being repaired. They decided to use six-inch discharge pumps, two each, into ten lines. This way, if one pump was to fail or was down for maintenance, we could still maintain the other two-pump system. Approximately 5,000 linear feet of ten-inch pipe would be installed over 2,500 linear feet of land.
