Google Cools Data Center With Bathroom Water

judgecorp writes "Google is cooling its data center in Douglas County, Georgia, using 'recycled' water that has been through the bathtubs and toilets of the surrounding community. So called 'grey' water is perfectly adequate for the data center's cooling system which relies on evaporation (the wet T-shirt effect), says Google."

      Strange but true: If you use water blocks to cool a server, the cdrom eject button pokes out an extra 1/4 inch due to the cooling effect. Of course I haven't seen a new rackmount box with an internal cdrom in some years, so I guess this only applies to racks that are sagging with age (ugh)

      Exactly.

      Of course, if you read TPWFA (The Poorly Worded Fine Article), you'll find that they are using neither grey water nor black water, they're using treated effluent from the local sewage treatment plant, which should largely be free of solids and possibly decontaminated (in Chicago, anyway, there's a controversy brewing because the treated water dumped into the river is full of nasty bacteria). They will have to treat it further - even clean, potable water needs to be treated when using it in a cooling system in order to prevent fouling of the equipment and possible microbiological growth. Then, as the article says, it gets treated again before it is dumped into the river, since the water accumulates dissolved minerals and other solids and because the treatment chemicals added may themselves be bad for the environment.

    Engineers have been considering approaches like this for ages. It's good to see it being put into practice.

    As best I can tell, one of the biggest hurdles is local waste-handling laws. When we had a local drought a few years ago, we were saving wash water to put on our outdoor plants -- but that was a violation of local policy, because cooties from your dirty clothes might get into The Environment, contaminating all the bird and squirrel and cat and dog waste that's already there.

    I'm sure Google's treatment policies have satisfied the local authorities, and if they're proceeding with the project, I'm sure they've found a way that's cost-effective.

      There is a form for everything. In some states in the US, it's illegal for you to collect and use rainwater for anything. States grant exclusive right to water catchment to various water companies, so for anyone else to capture that water before it reaches the reservoir is effectively stealing.

  13. Toilets != grey water by oneiros27 · · Score: 4, Informative

    What comes from toilets is 'black water', but 'grey water'. Grey comes from showers, washing machines, etc. It's specifically that which has been used, but has a low risk of pathogens in it.

    From the article, it sounds like they're using a blend of the two ... but they never linked to the March 15th Jim Brown blog post. From reading his blog, he states, "We worked with the WSA to build a side-stream plant about five miles west of our data center that diverts up to 30 percent of the water that would have gone back into the river", while the article linked to states "about 30 percent of the water is diverted from the WSA system".

    The article makes it sound like they're getting the water *before* it would have been cleaned by the water treatment plant ... from the blog post, I'd say it's after it's been treated, and getting it before it would have been sent back to the river. So it's treated wastewater, which would've already gone through some sort of system to remove pathogens.

  14. "Gray" vs "Black" water by swillden · · Score: 3, Informative

    Usually "gray" water is water from showers, sinks, etc. -- everything but toilets. Water from toilets, including human wastes, is called "black" water. Some systems keep these separate, although most municipal systems (including, it appears, Douglas County, Georgia) mix them together. So this water starts out as "black", but according to TFA, it's partially cleaned up before being sent to the data center. Apparently it's treated enough to be called "gray", but still isn't potable. Then Google finishes the water treatment and releases the result into the river which is where it would have gone after the county treatment center anyway.

  15. Firewalls by Kupfernigk · · Score: 3, Insightful
    My experience of firewalls and water treatment is this: that water treatment is designed and operated by some extremely professional people who know exactly what they are doing, and that this is not often the case for firewalls. Given how some firewalls are configured, the water treatment analogy would be to stop most things and restrict the flow of the water, while letting the really nasty bugs through.

    OT but possibly of interest: the daughter of a friend of ours studied environmental biology at university. Her mother wondered what use it could possibly be. As a researcher into water treatment, she is now into her second paid postgraduate placement with the prospect of a very well paid international job at the end of it. Oil may be sexier, but water is actually the more important resource.

    The summary (and Google) are being misleading here. This is treated sewage that would have been otherwise dumped in the local river - thus it is almost drinkable, and almost certainly cleaner than the river water itself. "Greywater" usually describes untreated sewage from non-toilet sources (showers, sinks, dishwashers, clothes washers).

Greywater differs from water from the toilets which is designated sewage or blackwater to indicate it contains human waste.Source: http://en.wikipedia.org/wiki/Greywater

    Reclaimed water or recycled water, is former wastewater (sewage) that is treated to remove solids and certain impurities, and used in sustainable landscaping irrigation or to recharge groundwater aquifers.
