John,
This kind of pipe is usually corrugated .. it holds water inside,
despite the 'drainage holes'. It's designed to take water IN and move
it.
Despite all the comments to put the cables in PVC .. I prefer burying
everything with my 'cable burying machine' .. a sled which I pull behind
my graden tractor. It has the ability to bury about 6-12 inches of
cable PER SECOND while I maneuver my tractor about the 'pasture'.
I use it to bury coax, rotor control cables, radials, etc..
