Up here I can open cut and install a pipe for about $8-10 per diameter inch per foot. Last time I looked at HDD it was $18-25 per diameter inch per foot for the size of pipe I wanted to put in. Plus, you still end up digging holes. I wanted to drill a 24" line, but I still had to dig pilot holes ever few hundred feet. In the past, you were also stuck with HDPE. For some reason we're so old school that we don't allow HDPE. π
I agree. You end up digging HUGE holes when working on the larger lines. I'm not sure where the benefit is in some cases.
