Mineral-free ultrapure water has a resistivity of 18.2 megaohm . cm. I'd call that "pretty damn non-conductive", personally.
Of course, eighteen megaohm water is capable of leaching sodium ions out of glass, so...
Yeh this is kinda my point...it is possible to make water fairly non conductive (although domestic grade distilled water is unlikely to be at the purity you define) but it is damn near impossible to keep it like that.
I have access to Reverse Osmosis systems that can produce water that achieves something like 0.06 microsiemens/CM of conductivity (which equates roughly to 18meg/CM resistance) but the only way they can do that is by keeping the water in the RO loop in constant cycle through the filters let it stop doing that and it will quickly go up.
Wayne,
You have access to Reverse Osmosis systems then could you filter a few litres holy river water from India, what are the costs and procedures for doing this?

I am afraid the systems I deal with need to be available all the time.
It wouldn't be possible for me to drain them down in order to fill from a different supply as they need to be continuously available (not withstanding the fact that after draining down I would need to re-sanitise the whole loop which is a fair amount of downtime) and in fact most of them are large enough that you'd need a significant amount of your holy water just to prime the filters.
