Well it seems a pretty good way to transmit water-borne diseases to me!
Soap is not going to have any significant protective effect (and detergent
little more). Both agents are simply designed to lift grease and such off
your plates - not to protect you from whatever in lurking in the water.
A good approach if she can't face boiling water for washing dishes is to
heat the dishes and flatware after washing (we used to toss it in the top
of the wood stove, which always had at least a small fire going during the
day) and give it a good cooking.
Finally, remember that some of the diseases (at least the febrile
illnesses) may be vectorborne, not waterborne, and no amount of
precautions with the water will help that.
