Nowadays there are a lot of greening the Earth campaign and ways of doing it but never thought of until the Google use the reuse water from the sewage to keep their data center system cool. This is another nice and efficient alternative method instead of building more and more air-conditioner machines that will contribute even more to global warming.
Here’s what they say about the details of recycling the water;
“A typical data center can use hundreds of thousands of gallons of water a day. When we first built the Georgia facility in 2007, the water we used came from the local potable (drinking) water supply,” Google explained.
“But we soon realized that the water we used didn’t need to be clean enough to drink,” it said.
“So we talked to the Douglasville-Douglas County Water and Sewer Authority (known locally as the WSA) about setting up a system that uses reuse water—also known as grey- or recycled water—in our cooling infrastructure,” it added.
Google will pull in 30% out of the overall reuse water from the treatment plant, goes up into the pipe cooling down the data servers, and the water will diverts which have not evaporated to another treatment plant which finally goes back to the river as a clean and clear water.
