What happens here

A worker uses a drill with a hole saw attachment to carefully cut circular openings into the end caps of the black plastic chambers. White PVC pipes are then inserted into these openings, creating the connections between successive runs of the drainage chambers. Once these connections are secured, the excavator begins to carefully push soil back into the trenches, starting the process of burying the installed pipes and chambers.

Goal: Securely connect all drainage chambers with PVC pipes and begin the initial backfilling of the trenches.
