They use them lot around here--specifically for FIOS vinyl/rubber cables....
They are pretty neat--but messy to use and a lot of manpower involved....
They pump water along with the drilling bore's to stay cool, I suppose---and every so often have to dig a hole for like-sight of line...As the power ram reaches it's limits--they pull it back and add more length..
Then they put the borer -thing on the machine that makes the whole bigger....
It takes a whole truckload of pipe extensions, sometimes, to get where they want to go. Muddy mess @ both ends if it's wet at all.
Here -also, I've noticed mostly sub-contractors to the local utility company, and most labor is , shall we say 'from south of the border"..
NO other way to describe it....:dunno:
Still--neat concept and I'm sure--cheaper and quicker than digging trenches and back-filling..
