I have a building with all plastic water lines except about 6 inches of 1-1/4 metal pipe from the street where the main shut off valve is. I have the gas piping system already bonded. Can I run a jumper to the water main from the gas line or does it need a separate bond wire from the main service?

If all you have is a 6" section of metal water pipe then this section doesn't need to be bonded as it isn't a "piping system" just a short section of pipe.
Is this section of water pipe that is run underground to the street at least 10 feet long?
If it is, it would constitute a grounding electrode and would need to be used as such.(See 250.50) If you use it as a grounding electrode you must run a either a bonding jumper from another electrode to this or run a GEC from the service to the water pipe. You can run a bonding jumper from the water pipe to the gas pipe but not from the gas pipe to the water pipe.
