I have seen, on occasion, folks on this site whose situation would call for the use of some flavor of trenchless technology -- this guy is the most obvious example, but others have come up.
However, it seems that directional drilling requires a skilled drill operator to run the machine, and pipejacking may not be possible for DIY-sized pipes, just culvert-sized ones. Is moleing the only option for a DIY trenchless job, assuming your local tool rental place carries a mole and a suitable air compressor? Or does moleing require a similar level of training and skill as directional boring or pipejacking would?
(Of course, you call One-Call and get all the utilities marked out thoroughly, but you'd be doing the same if you were digging a trench, so that point isn't an issue.)
