Drilling holes in conduit for drainage is not a good ideal. It going to be full of

in the same conduit, It you using hard line just bury it in the trench. 73 and good

CHeck your local codes, if you're concerned. around here (Thousand
Oaks), UF is not allowed for direct burial. Underground has to be in a
raceway (code speak for conduit). There's various burial depths
depending on the kind of conduit (plastic, thinwall metal (EMT), or
thick wall metal) and whether it's under a concrete slab or similar.
The depth is all about damage to the wires (since frost is a non issue).
