Just to be pedantic, as this is the Internet after all :-), distilled
water is a pretty good insulator, but not a "perfect" one. Neutral
(pH 7.0) water always has a very small amount of the molecules
disassociated into H+ and OH- ions. However, as others have stated,
the effective value of the water resistor, compared to the load
resistor(s), will be negligible.
