Wayne, You are probably on the right track. The whole CS power supply and electrodes should probably be isolated from everything else with little way for the current to get to the earth ground from the anode. Metal pipes and tanks should be earth grounded somewhere. Of course, it all depends on the setup.
If it is an all metal system, a section of the metal pipes could be removed and a section of plastic (non-conductive) pipe or water channel put in with the CS electrodes in it, operating off an isolated supply. The original metal pipe system should have a ground strap across the area of the CS cell to provide the ground that was lost between the two sections when the insulated area was put in between. I would still put an additional earth ground on the output side of the strap... Also, depending on the system, as Marshall says, it may be easier to set up something with two plates for electrodes than a wire in the center of a pipe. There is more than one way to skin a cat (fish)...

I might see the safety issue a little different. Possibly not if you got to the point of final design and assemble. I don't see the DC as a shock hazard, even if 24, 36. or 50 VDC was used. Any good power supply will have an isolation transformer to protect from any AC voltage. Of course if one chooses to get shocked by both DC sources, he can always do that. The current should be limited to a low value which adds additional safety. Any 120 Volt source used outside near animals or humans should be GFCI protected. In many areas there are virtually no electrical codes and no one to enforce them. This means the person that designs and builds any electrical system has safety in his hands. I see the simple mechanical design differently I feel sure. I would use an enlarged pipe to contain the electrodes, 3 to 4 inches at least. Possibly even 5 or 6 inch. Anytime I drill, tap, and install special devices in pipe, I use schedule 40 or schedule 80 and certainly not the thin wall stuff which breaks easily and is too thin to tap effectively. The spacing of the electrodes would have to be selected and the pipe tapped to accommodate this. Depending on the electrode mechanics, a special fitting may have to be made, but still, this is no hill to climb. Actually, the more we think about it, the simpler it becomes. You mentioned the controls which is straight forward to cut off when water stops flowing. I can't see any special grounding as being required. Of course metal tanks, fences, gates, ect. near any line voltage should be grounded anyway. So, normal safe grounding practices would suffice. I may be missing something that you see. If neither side of the DC was grounded, I see no path for any current flow other than from electrode to electrode. Do you see one?
