Answer:

Because the concentration of charged particles in pure water is vanishingly small.

Explanation:

We know that water does undergo autoprotolysis:

#2H_2O(l) rightleftharpoons H_3O^(+) + HO^(-)# #K_a=10^-14#

At standard (and higher) temperatures, the #K_a# value is quite small. The result is that water is a poor conductor because of the absence of species that can carry a charge.
