A close shot of the grounding electrode conductor as it enters the main electrical panel.

This is how a water meter should be jumped out with a ground bonding jumper. #6 copper wire is sufficient, but it is #4 in the picture. The purpose of the water meter bonding jumper is to maintain grounding continuity on the water pipes

In addition to the other bonding and grounding, I also bonded all of the interior metal piping which includes the cold water pipe to the hot water pipe and the gas pipe as required in article 250.104 (A) and (B) of the National Electrical Code . If this house contained a hot water baseboard heating system with metal pipes, those would have to be bonded to the cold water pipe as well. It is very convenient to bond all three pipes at the water heater and they are accessible for the inspector to see.
This photo depicts the water meter and the bonding jumper connection points on each side of the meter.
