Uses siphoned waste water and purifies the rest.
Google has always tried to look for greener and energy-efficient ways to cool its massive datacenters, be it through using outside cold air or even seawater.
But the search engine company announced recently that they were going to proceed with a plan to use recycled waste water to provide cooling. Essentially the water that goes into the cooling systems doesn’t have to be drinkable, so Google used this new idea for its datacenter in Georgia. The massive datacenter siphons off 30% of waste water from a nearby water treatment plant, and pumps any unused water into a nearby cleaning plant where the water is purified and pumped back into the local Chattahoochee river.
It’s an exciting idea that will help the company drastically reduce the footprint and cost of cooling datacenters, and while it’s not a model that can be adapted everywhere it’s a prime example of how large companies like Google are trying to better adapt more eco-friendly practices in a power-hungry world.
