I thought about that, but only briefly.

The plumbers used a riding trench digger to put in the trench. I specified 45 degree bends so the trench goes fairly deep.

We are building in a forest and had to cut down two 100' tall pine trees plus maybe 15 other shorter trees within the area of the slab. Some of the horizontal roots in the trench were 5" in diameter. Plus the soil is a very dense, plastic clay. Digging that trench by hand would have taken me several days and probably laid me up with back pain before I could have finished the job.
