Typically in this area (SoCA):
Customer supplies and installs all conduit, including primaries, that relate to their job.
Customer supplies any transformer pad, slab box, or vaults and grounding necessary.
These immediately become the property of the utility.
The utility supplies the cable, transformers, and metering. The first 100 feet of cable used to be free, but since deregulation, they charge for everything.
This has caused us to exclude any and all power company charges from our bids, as one doesn't know how much the charge will be until way too late in the construction process.
I've never heard of weep holes in a conduit. To do so here would cause you to miserably fail the utility inspection required for a service. We don't have an ice problem. The conduits going up the pole are wide open at the top (first 10' up must be schedule 80).
On some of the taller risers, I've seen wedges inserted at the top, but these are for mechanical support of the weight, and are far from watertight
