Google Cools Data Center With Bathroom Water 230

Posted by samzenpus from the flushing-cool dept.
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."

    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.

        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.

Heavier particles sink to the bottom. The water enters the second chamber via the connection and is mainly clean of any swimming particles, while still containing some heavier soli

      An almost miniscule portion of said mud does so - because the designers of such reservoirs aren't stupid and place the intakes well away from the shores/edges and inflows, where 99.9999% of such debris is. Not to mention you vastly overestimate the amount of mud and debris "whipped up" in the first place.

    What comes from toilets is 'black water [wikipedia.org]', 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 [blogspot.com]. 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.

      There's a park I've been to a few times and it has a beach.
      The park also has a water treatment plant in its midst that discharges into the waters of the beach area.

      I got to talking with one of the park rangers and he told me he wouldn't let his dog swim in that water.
      "Treated" doesn't necessarily mean what we think it means. It isn't sterile and you shouldn't let it get into any mucous membranes or open wounds.

    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.

      Though TFA did not really say, they would not typically be directly cooling the data center with water cooled by evaporation. They would be rejecting heat from their refrigeration equipment (probably water chillers, possibly other types) and using the refrigeration systems to cool the air. The advantage of a water-cooled AC equipment is that the cooling tower water is typically heated up by the refrigeration equipment from 85F to 95F and then cooled back down by evaporation.

    They're not using greywater. Greywater is untreated non-human-waste water, like from sinks and showers. Google is using the water which has already been treated by the waste water treatment plant and would otherwise be delivered back to a river. It's not pure enough to drink, but it isn't bathwater. It's purity is somewhere in between tap water and river water, with almost zero "floaties".
