I would suggest mechanical-joint cement-lined ductile iron, but I do not know how you are going to drain it short of putting in a pit.

The underground connecting these two buildings is to be part of the pre-action system (piping filled with air). In other words, the pre-action valve is in building A. The piping runs underground (after the valve) to building B. This is a new one for us. My questions are what type of pipe do you use for this purpose and how do we drain the water out of the underground? I appreciate any info!
