My manhole in the yard is in a low spot and has an open 
bottom with gravel. The conduits all slope down to it.

Where they don't do that, like in the island to the 
building, I drilled drain holes in the pipe and set it on 
gravel. Other pipes are the same way, either open at a low 
spot or with drain holes in low spots. You can see I mostly 
cut a "hood" with an angle cut. I have to go back and finish 
a few like that, but in the mean time I don't seem to have 
any water problems. I also pull flooded cables, ones with 
goo inside, or use hardline. The 5/8th inch (50 ohm) 
hardline and the 50 ohm that looks like RG8 are flooded 
cables, but the rest are just normal heliax and are never a 
problem even when directly buried.
