In this picture you can see a trench in the ground about a foot or two deep. There’s a yellow string attached to a rebar next to one of the beds on one side and another rebar on the other side, which creates a straight line for the worker to make a trench along that line. In the trench they are going to lay a water pipe to channel water to the garden for sprinklers.
