Google Cools Data Center With Bathroom Water

samzenpus posted more than 2 years ago | from the flushing-cool dept.

Google 230

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."

That's what I thought too, but when I asked the plumber to install two separate wastewater systems in my house he looked at me funny and insisted that they would both end up in the same sanitary sewer as he wasn't allowed to connect either to the storm sewer.

I told him I didn't care, and I don't mind spending the extra money, so now my shower water is separate from my toilet water all the way up until they exit my house.

Wait, let me get this straight. By adding a completely separate, unnecessary and redundant wastewater system in your home that dumps into the same sewer pipe anyway, you are helping the environment? You realized you caused more resources to be consumed, more labor hours, the plumber probably had to drive his 8-cylinder work truck around town to get more parts, etc. etc. But somehow that helps the environment?

Re:Shit (5, Informative)

MightyYar (622222) | more than 2 years ago | (#39402503)

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).

Re:Shit (2)

busyqth (2566075) | more than 2 years ago | (#39402571)

Correct, but the somewhat interesting part is that Google built their own wastewater treatment plant to supply the data center with coolant.

Re:Shit (1)

MightyYar (622222) | more than 2 years ago | (#39402685)

Actually, they built a wastewater plant to treat the water that already passed through the data center - and I suspect that was a requirement even when they were using tap water... I highly doubt that you can dump any kind of industrial wastewater without "treating" it, even if treating just means putting it in a big open-air tank to let it settle and testing it once in a while.

Re:Shit (1)

Wilf_Brim (919371) | more than 2 years ago | (#39402679)

Clothes washers are somewhere between grey and black. Where to place them is a bit of a controversy/dillema in those that think about such things. In most situations they are grey water. However, when diapers and the like are washed there is a much higher concentration of fecal coliform contamination than usual: the water is a very dark shade of grey. Washing diapers has become a bit of an edge case, but it is frequent enough to screw up placing the effluent from a clothes washer into a grey water stream.

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.

Re:not a good idea! (2)

Sarten-X (1102295) | more than 2 years ago | (#39402005)

The pipes that carry water to the systems would likely not exist.

Rather, like most cooling systems, the water is likely used to cool a heat exchanger, which in turn cools air that's blown into the server rooms. If a pipe gets clogged (which is unlikely, since the pipes have little reason to be as small as household ones), that heat exchanger just won't be as cold for a while.

Re:not a good idea! (1)

Igarden2 (916096) | more than 2 years ago | (#39402205)

From TFA:
"With the evaporative cooling method employed in the data centre, cold water is brought into the facility, where it’s used to cool the hot air from the servers. Some of it evaporates into the air via cooling towers, while the rest remains as a liquid."

Google is trying to be a good environmental citizen by making use of grey water instead of requiring fully treated water which requires significantly more energy and chemical usage, what possible reason could you have for trying to dissuade this behavior?

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.

Re:Hooray for common sense. (2, Insightful)

Anonymous Coward | more than 2 years ago | (#39402159)

While it may sound ridiculous, it becomes less ridiculous once you remember that many states are almost all desert, and thus water collection and usage really does need a management system that wouldn't be the case elsewhere.

Firewalls (3, Insightful)

Kupfernigk (1190345) | more than 2 years ago | (#39402143)

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.

Re:Faced with all the stupid comments above (2)

Sique (173459) | more than 2 years ago | (#39402721)

But normally you don't use the sieve type of filters. Sieves tend to get clogged very easily. Normally you use a three-chamber-system. The first two chambers are connected near the bottom, the third one connects to the second chamber via a spillover. Untreated water enters the first chamber, and all swimming particles stay there. 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 solid material. The water entering the third chamber via the spillover is mostly free of any particulate matter, because all the remaining particles stay in the second chamber. The third chamber then gets emptied via an outflow at the bottom.

This water can still contain micro particles which neither drift to the surface nor sink down to the bottom. Thus the water can be treated via an micro filter, e.g. a bassin with reed it enters at one site and an outflow at the other. Except for the substances soluted in the water, the water is clean and can be used for most applications.

Toilets != grey water (4, Informative)

oneiros27 (46144) | more than 2 years ago | (#39402055)

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.

"Gray" vs "Black" water (3, Informative)

swillden (191260) | more than 2 years ago | (#39402139)

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.

Yuck, swamp coolers in Georgia (1)

Re:Yuck, swamp coolers in Georgia (1)

jbengt (874751) | more than 2 years ago | (#39402421)

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. Whereas air-cooled refrigeration equipment typically has to work against air temperatures of 95F to 115F, creating a less efficient cycle.

Let me guess.

The servers are all going to overheat on Seis de Mayo. All the spicy food the day before will be warming up the cooling water.

It's fine... (4, Funny)

It's not greywater. Read the danged article. (2, Informative)

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".

But yay poop jokes. Who knew /. had so many 4th graders?

Grey water is under utilized, even in the home (4, Informative)

My g/f's from Japan and when we went to visit recently I noticed a lot of homes had toilets with a sink built into the top of the toilet tank. When you flushed, the water to fill the tank came out a faucet and you could wash your hands with it. Not only recycles but saves room in a 1/2 bath... a simple little thing we should see more of here in the states. As an example... [treehugger.com]

That is a great idea. I don't live somewhere with a water scarcity problem (I don't even have a water-saving washing machine), but that is a good idea.

Sounds like a pretty crappy design to me.

Recycled water rulz (1)

kurt555gs (309278) | more than 2 years ago | (#39402653)

There are small systems that can produce recyclable water even for single family homes. The National Sanitation Foundation now has NSF Standard 350 so manufacturers can test to a protocol and become certified. The water can be used (depending on state code) to fill toilets, urinals, water the lawn, wash your car, lots of non potable uses. Right now there is only one device certified, the Bio-Microbics Bio-Barrier http://www.biomicrobics.com/?p=59 [biomicrobics.com] However several other manufacturers are now testing. Recycled water is no longer limited to large facilities.
