Don,
Normally houses (or structures) next to one another would be out on a 'branch' of the water main, wouldn't they? I was thinking about the service being bonded to the waterline out at the 2nd structure and it then running back through the first House. The waterline at the 1st house is bonded to service neutral also. Wouldn't there be current flow on the waterpipe all the time? One thing I'm thinking of is someone doing any plumbing work could be in danger, especially if one of the service neutrals went bad and no one knew about it.
Also, wouldn't/couldn't there be some difference in potential from this waterline to other conductive objects in contact with earth?
