I have two 200 amp service boxes (320 amp service). My water distribution tubes are not grounded to the exterior (water service is plastic). What gage wire should I use to ground the interior water distribution system, which is copper? I can interpret the code to require as little as 8 or 10 gage or as heavy as the combined service cables.

Why are all these DIY questions on how to properly install electrical services? Adding a circuit or two should be within the realm of a DIYer but services are serious business.
What you should do is take a four year elctrical curriculum and get 4000 hours of on-the-job training. Do you have a permit? What are the license requirements in your state? Do you have a copy of the NEC? The answer is in there, somewhere.
What is the difference between earthing and bonding? Hint: since you have a plastic water supply,, you will need a Ufer ground and perhaps ground rods. The bonding of the copper water pipes would be according to the amount of columbs that are likely to potentially energize or come in contact with the pipes.

I think you are right and you should retaliate. Go to the dentists' forum and start a thread on DIY root canals...

I beleive Luka could contribute to a root canal thread. Recall a while back on DIY surgery thread (stitches and such) he did say he actually had done his own dentistry!
#8 is ok for grounding the water pipe.
What is a columbs.
Is your response april fool?
Is a columbs a column that holds the pipe or what?
actually, what eye fonud on the redneck Wizecrackerpedia, is that a columb is the product of a concubine and an newspaper columnist. A second definition is that when you take the time integral of lamps (invented by the famous Lamphrey, an associate of Ampery, and has units one less than a six-pack) you get a product that is the same result as your ability to hold beer (capacitance) times your potential to stay sober (named after a famous italian frogleg experimenter)0 especially if quaffing a high voltage and measuring you ability to hold a product like 'steel reservoir'. There is also and associated unit called 'S' for 'seemans', which is inversely proportional to a lady's hesitation (an OOOOH'Mah).
The the instance above then, the columbs refers to the rigidity of the 3rd leg in mantaining you standing or in an erect state while integrating vast amounts of lamps.
It's spelled wrong
obviously - april 1, remember?
figured the wierd phrasing "according to the amount of columbs that are likely to potentially energize" was an invitation to deviate into 4-1-2006 replies.
