There seems to be some confusion about the use of water as a
dielectric.  Water can only store a charge for a short time, typically
microseconds. It is useful in pulsed power systems as a fast capacitor
to charge in microseconds and discharge in nanoseconds, but it is not
usable in a DC or low frequency capacitor no matter how pure the water
is.
