That's just not possible, PE is legal for pressures under 99psi, all in
town
distribution systems have pipe pressures well over that, they have to
maintain volumn. Even a small town will have distribution mains running
200
to 500 psi. and from 2" up.
As far as services go, steel services run off steel mains and PE services
run off of PE mains.
Maybe you haven't seen them, but there are quite a few steel lines in your
area.
You just can't run an entire dist. system with pressures under 99 psi.
Especially in the winter.
All this goes out the window if you are in Mexico, Gautamala, ect. But in
the U.S. it will hold true.

Not going to argue with you, been there, seen them bury and connect mains.
I was told by the utility that they run 50 psi in the mains, I have seen
them run 2" and 4" poly. I know they have larger lines.
