That's because it's a large industry and nobody lives there. This pattern appears all over the place. The paper mills in the pacific northwest consume large multiples of the water used by their little towns.

That's not the point, the question was whether an apartment building would use the same amount of water and clearly an apartment would consume substantially less water.
No, the question was whether "the same size space of apartments" (i.e. apartment buildings occupying the same land area as the datacenter) would use more or less water than the datacenter.
Under reasonable assumptions, the apartments would use more water.
- Google's datacenter complex in the Dalles covers ~190 acres.
- Typical density for apartment buildings is 50 units/acre, meaning you'd have 9,500 units on 190 acres.
- Average household size in the US is 2.5, so the 9,500 units would have a population of 23,750.
- According to the original article, per capita domestic water usage in the U.S. is 82 gallons per day, meaning a total water consumption of 710M gal/yr for the apartments. And this doesn't count the substantial indirect water usage you'd need to support this population.
- The Google datacenter uses 355M gal/yr (per the Oregonian article).
- 710M > 355M
Now, it would be somewhat ridiculous to replace the entire Google datacenter with apartment buildings in a rural town with declining population, but that was the original question...
If you replace the area of that data center with apartments, as the question suggested, it would add half again to the local population, which could indeed use 30% of the city water.
I'm not understanding the logic. You want to add more population to the city? That doesn't seem fair but I'll concede I may not understand the point you're trying to make.
Assuming that the population is the same in the city and you just move residents into an apartment complex. I don't understand how you would get the same water consumption, am I missing something? Evaporative cooling is extremely water heavy and these facilities also have the normal HVAC you'd expect. Everything just seems to point to more water usage not less.
