I've seen cable brought down from a pole, so no conduit, or run underground in a flexible black PVC tube that pops up out of the ground within a foot of the building. The tube end points upward. Thus it can collect rainwater or sprinkler output. I'm sure every one of these has water in it after a year or so.
