By your own source the vast majority of that use is agricultural and industrial [1]. If you look at say, Germany they use 19.68 billion m^3 for municipal purposes vs 58.39 in the US, but the US population is about 4x that of Germany, so Americans use less water than Germans(for example). The Japanese use a little less per person for municipal purposes, but not by a lot.

People are down voting you because you're muddling domestic use with agricultural and industrial numbers and you're being a judgemental asshole. And you can't be both innumerate and an asshole at the same time here.
