Stan,
Of course holes on the bottom of a buried conduit will allow water to drain out
if the pipe was filled during a temporary rise in the water table, assuming the
surrounding soil will permit percolation. But the only reason water got in
there to begin with was that you put holes into the conduit! The point is that
if the condensation of a tiny amount of airborne moisture is an issue, then
having the contents of your conduit flooded anytime there is a rainstorm is a
bigger issue!
Condensation is really a non problem.

I always assumed burying conduit with a bed of gravel under it and holes down
was kinda like a septic line where any accumulation of water from whatever
cause would likely drain out. Certainly contrary to what you write, Al, I
would assume it better to have the holes down as opposed to saying it doesn't
matter. Water won't find its own level other than the one created by a solid 4
inch diameter pipe with holes on top. It could fill with standing water and be
there for months while the ground around it had no appreciable water content.
