As long as you can maintain 12" of clearance between all utilities, they can
go in the same trench. We routinely run 13.2 KV primary cable (in conduit)
in the same trench as water, telephone, CATV, and gas ... in Florida. Best
bet is to check with your power company and see if they require greater
clearance. Some utilities have their own standards which exceed the NESC
requirements.
