So, after my last post , I spoke of use of grey water from the sanitation (after a sump tank ) poured over the earthing/grounding connections . Right after that i stumbled on this prescription in the Indian Standards IS 3043. (drawing altered to show plastic earth pit)
so the standard prescribes that water to be flowed over the earthing set up.
Grey water from the toilets of a facility will definitely work......Also Do the job and also support water conservation..
