Here, we are in the process of backfilling the 72" Metal Pipe on this particular system. We started by placing and compacting #57 clean stone underneath and half way up the sides of the pipe to serve as a cushioning agent and to prevent to pipe from "ovaling." After which, our crews worked hard to compact dirt around the rest of the areas in 1' lifts. Once we fill our way up to the top we will then be able to safely place some heavier compaction equipment on the system to speed up the process. The purpose of this system is to store rain water that we may encounter in the event of flash floods or some of the longer rain storms that occur in this area.
