250.104(B) is probably what you're asking about. That passage is pretty explicit.
But.
There is this thing with CSST (corrugated stainless steel tubing) where those manufacturers require a bond that is much larger than what the NEC, and 250.104(B) requires.
The actual physical location is pretty much driven by convenience, except for CSST which tends to need to be on the load side of the gas meter on a convenient piece of rigid.

Water: Depends:
When the water line is an electrode: See 250.52
When the water line is not an electrode: See 250.104 (A)(no specific location)
Gas: See 250.104 (B) except for CSST the see Al's post above.

If not CSST, the gas pipe is grounded through the gas appliance it's connected to. Typically a gas boiler, oven or stove. No further bonding is required.
