Water pipe bond , in conduit with feeder?

[Flex]

Bringing a new service to an existing building. Adding new gear in the back of the building that will be the main service. Existing electric room and water meter are in the front corner of the building. We are refeeding the old gear from our new gear, with approximately 200 feet of conduit through drop ceilings. Can I pull the service water pipe bond in that conduit with the new feeders for the existing electrical room? Or does it have to be seperate of all that...obviously im tryin to save some labor goin back through with an open cable.

If it turns out to be legal and the conduit is steel 250.64(E) will come into play.

I don't know of any prohibition. Conduit fill restrictions and bonding mentioned by jumper do come into play. Opinions that it is allowed may vary, however
