Trenching and Installing Drainage Chambers

What happens here

The excavator proceeds to dig the trenches for the drainage field. A worker uses a grading stick and laser level to ensure that these trenches are dug with absolute precision, emphasizing the necessity of them being "laser level" for the system to function correctly. The black plastic drainage chambers are then carefully placed into these trenches. The worker demonstrates how these chambers snap together and explains that they are perforated, allowing the liquid waste to absorb into the ground through the sides, rather than seeping from the bottom. The total length of the drainage system is stated to be 481 feet, composed of 112 chambers.

Goal: Dig precise, level trenches and install the perforated drainage chambers.
