Grounding to water main

Have a 200A service in single family home. I buried my 2 ground rods and ran my ground wire from rods into panel. I have no water main coming through foundation. I have well water. from well i have pvc pipes coming through my foundation and straight into pump motor. From panel to what do I attatch my ground to?

You do not need to bond non-metallic water lines.

So just from rod to rod to panel is a sufficient ground in this case?

Your question (From panel to what do I attatch my ground to?) is nonsensical. Your SERVICE panel, the one that is supplied directly from the electric meter with no intermediate panel or switch, is where the grounding electrode conductor connects. It connects to the same bus as does the neutral (white) conductor from the meter. This bus is also bonded to the metal enclosure.

Since you have no metallic water piping you do not need any ground connection to the water piping although bonding all metallic water (and gas, if present) piping back to the equipment grounding bus in the service panel IS a good idea.
