Underground vs. Underground?
Underground vs. Underground?
(OP)
How can we decide if a pipe should be U/G or A/G?
As far as I know, A/G is the default because is cheaper. But for some specific reasons, it is better to do U/G. One of these reasons could be "protection", like fire water or potable water. Is that correct?

RE: Underground vs. Underground?
In Iraq, if all those petroleum pipelines had been buried, it would have been much more difficult to have sabatoged them during the recent times of turmoil.
So the reasons for burying lines can vary from freeze protection to damage protection and pilfering protection although there are stories of people digging down into the ground to gasoline pipelines in California and tapping into them and stealing gasoline so who knows?

But the repair& maintenance/Healthy keep-up becomes fairly difficult as well as costly.
In certain areas of relatively minor level sabotage/temper risks 1 meter underground does prove sufficient deterrent in general.

Materials of construction, impact resistance, access, safety, contents, location, pipe supports, expansion (both facilities and pipe expansion).
It is usually cheaper to go above ground on brown field sites.
