       | There are areas with lots of land, water and much lower ave air
       | temps in the US and some have empty buildings that can be
       | retrofitted for use as data centers. But no, lets build in places

         | 
         | Why would a for-profit not hurt the environment for more profit
         | if it isn't illegal and won't get them sued (for more than they
         | profited)? There's a rich history of them doing exactly that.
         | Similarly, governments have done horrific environmental damage
         | and it was up to environmentalists to create the awareness to
         | make it stop.
         | 
         | I honestly don't know how you can look at a world with record
         | numbers of wildfires, communities fighting over water supplies,
         | and for-profit companies say that water beyond subsistence
         | levels isn't a human right and think "oh yeah,
         | environmentalists are looking for a reason why this water-
         | consuming thing is bad".
         | 
         | Especially when the same technology could be powered in a way
         | that doesn't pollute as much and cooled in a way that doesn't
         | consume as much water -- if only the environment was more
         | important than shareholders.

       | Honestly, 6500 households of water a day is nothing. Individual
       | cities often write more than this off in a day when rain
       | overwhelms their watershed systems.
       | 
       | Even with perfect watershed recovery our ability to treat,
       | utilize, and transport it back without losses is a far bigger
       | concern. The average age of pipes in the US is approaching 50
       | years old. I've seen reports project the US will need to invest
       | nearly 1T in the next 15 years to sustain the current system and
       | rate of growth.
       | 
       | Hell, there was a 54 inch water main break in Detroit this winter
       | that flooded ~120 homes. A conservative estimate for a pipe of
       | that size leaking all of its water for 5-6 hours is 20-25,000,000
       | gallons of water. We're going to be seeing a lot more of that.
       | 
       | Another thing I see overlooked constantly is that many of these
       | DCs are augmented with their own filtration systems which allow
       | them to primarily consume greywater for a net gain.

         | change to how much water is available.

           | That completely misses the point, it's a harbinger. This area

           | freeze-thaw cycle.
           | 
           | Merely building a functioning bypass for a pipe of this size
           | at this depth takes the better part of a year. Replacing it?
           | Out in the suburbs some of the projects to repair pipes from
           | the 40s that leaked and caused sinkholes are still ongoing,
           | they started over 20 years ago.
