In a couple of the data centers, Google is recycling 100 percent of such water, reports Geek.
The practice means that Google will be able to claim a lower impact on water supplies, an issue that figures to be more and more of a concern.
Joe Kava, Google’s Director of Operations, told Data Center Knowledge that, “Water consumption isn’t a side thought; it’s part of our larger environmental management policy. In the future this will be at the forefront of data center operations.”
A 15-megawatt data center can use more than 350,000 gallons of water a day.
In addition to collecting rainwater, other ideas being pursued by Google are to tap into water from a canal and recycling municipal waste water. In both instances, Google said that by avoiding municipal tap water, it is easing demands on local infrastructure.
