FILE - This June 6, 2013, file photo, shows the National Security Agency's Utah Data Center in Bluffdale, Utah. The massive National Security Agency data center about 25 miles south of Salt Lake City is using far less water than expected, utility records obtained by The Salt Lake Tribune show. Records from the city of Bluffdale, which sells water to the facility, show monthly water use at the $1.7 billion data center peaked last July at 6.2 million gallons. That's well below what the 1 million gallons a day that the U.S. Army Corps of Engineers predicted the center would need to cool its computer processors. (AP Photo/Rick Bowmer, File) less
