Also in a underground service does the power company supply the wire from the pole threw the conduit to my meter?
As was said already most utilities do not use any form of W/H to keep water out of their conduits. It would be a waste of time and money since it isn't sealed at the other end(below grade pedestal or padmounted transformer). However if a cust installs a riser on a pole it MUST have a W/H installed for reasons already pointed out by others. The utility I work for does not furnish conduit,wire or labor for a customer to pipe up the pole. All of this is at the expense of the cust. Even in URD installations we do not provide a service drop. Only in overhead distribution areas is that provided. Also required here is SCH80 PVC or rigid metallic conduit for the entire length of the riser. Found that out the hard way by installing SCH40(its bad when you are a lineman for a utility and don't know your own rules)geez.
CHeck with your local utility to see what is/ isn't provided.
