Not all water meters are buried. Mine and most in my area are in the

Yes... but that's not to make the pipes a better grounding electrode,
it's to prevent current from flowing through the meter and damaging it
from galvanic action.
The plumbing is also connected to
the ground rod. I have two 8 foot ground rods 8 feet apart,
connections have to be brazed if they are buried (local requirement
Actually, not brazed, but more likely "exothermically welded" a process
using a thermite mixture of copper oxide and aluminum powder. Basically
welds copper to copper with copper. (Brazing is using a different filler
metal). A commercial product is "CadWeld"... you get a little ceramic
mold that fits around the rod and wire(s), fill with the powder, light
it and stand back.
My plumbing is all copper including the line in from the
