Non-destructive location of utilities is a lot more valuable than you might think. In places like intersection there’s just so much going on and any improvements require accommodating, underground, utilities that have been around for many years, including things that would just not occur to a normal person like pipes made of wood that are from the early part of the last century. It’s pretty amazing how far subsurface utility engineering has come.
