What are the code requirements for crossing a buried electric line (from meter to panel) with a sewage line?
Here it's not an issue: Sewer lines have to be below frost line, so they are put at 8 feet. Electrical lines are, I think 3 feet, and can be less if protected. This of course makes it difficult to run a sewer line after the electrical is in.
I would try very hard to keep buried lines from crossing. SOMETIME one is going to be dug up for maintenance.
