At our datacenter in Belgium, The Nimy Blaton Canal on the north side of the site serves as the source for raw makeup water. The intake chamber is protected by a steel “dolphin” unit, which ensures that the intake will not be blocked or damaged by ships or large debris. The Intake Chamber has (2), stainless steel intake pipes each with isolation valves. Each intake is sized for 100% of the total site capacity. A compressed air tank periodically discharges across the bar grates to dislodge any material that may accumulate. Downstream of this Intake Chamber is the Metering Chamber to allow access for the local water authority. From here, water flows to the Distribution Chamber, where initial solids settlement, and hydrocarbon sensing takes place, and then flows into the 20,000 square foot Treatment Plant. The plant consists of three main lines each capable of treating cooling tower makeup water for one third of critical capacity. A combination Sand, Oil & Grease Separator receives the water as it enters the plant from the subgrade piping. Aerators are used to disturb the water during the separation process. A conveyor removes the sand from the fluid – and the suspended solids are skimmed off and deposited in to containers to be recycled. With most of the solids removed, the water is passed over a Lamella Clarifier so that the remaining particles will settle out. This clarified water then flows over a V-notch weir, and finally out to an open topped, polyethylene buffer tank. The buffer tanks provide a net positive suction head for the pumps below. Sludge removed from the settling processes is emptied to a sub grade sludge chamber. From this chamber centrifugal pumps move the sludge to a cyclonic separator to remove all the water. Once the sludge is dry, a screw conveyor deposits the material into storage containers for removal. The dried sludge is used for landfill, and as a filler component for cement manufacturing. The piping to the various tanks and process equipment within the plant is interconnected for redundancy and concurrent maintainability. Duplex pumps are used to pump the clarified water in to Sand Filters. The water trickles through the beds of sand in the filters and is further clarified in this process. The treated water is stored in the 3 above grade water tanks where chemical treatment takes place to control microbial growth. The water is pumped from the Canal Water Treatment Plant to the cooling modules via underground, parallel redundant distribution pipes. A distance of 30 feet separates each pipe, and the mechanical yard is fed from both lines in a looped fashion for increased redundancy. Samples of the canal water, before and after treatment, show the effectiveness of the water treatment plant.

  1. 20,000 square feet? 30 feet? If this is Belgium, shouldn't this be expressed in square meters and meters? This is very concerning.

  2. I'm an engineer, it can be both an isolation valve AND a gate valve. It is a gate valve used to isolate the raw water supply line.

  3. Ahh so a form of large-scale water cooling, not unlike that used in enthusiast PCs.

    Thanks, makes perfect sense now =)

  4. Near the Nimy – Blaton Canal, closer to Nimy and near Mons. I actually have no idea where any of those places are, I just googled it.

  5. To keep the server cool, 1000 severs or more in 1 room, it can get really hot and over heat without the cold water, And the massive quantities left over is a buffer zone to keep it running .

  6. Google now has over 500,000 computers to keep the website up and running and they are now installing another 100,000 every 3 months. they gonna need alot more water, but still i wish we had as much water as google has in brisbane here, WE GOING DRY AHHH!!!! google should share some te he 😛

  7. Servers and computers in general get very hot. Google has 400,000+ servers and increasing scattered around datacentres around the world. To cool the rooms of servers you need water, lots of it (similar principle to air con?). I guess instead of buying water supply they want to try recycling to help the environment and save money in the long run. Hats of to them.

  8. i think should look at sacred geometry and starting a new computer language more efficient, anyone done some research one this topic???

  9. Drinking water is held to a more stringent standard than Google requires so yes in the long run it would be cheaper for Google to build a plant.

  10. @paul417791 It would be hard to get that water there but you wouldn't be able to drink it… you can't drink sea water!

    Actually, you may be surprised to know that China is actually starting to increase its' high-tech jobs, and in some cases is actually starting to export the manual labor to america(I'm remembering an article on a high tech solar cell company operating in china; forget which one specifically). Doesn't mean the capacity is particularly distributed, but it is starting to get there. I don't agree it's light years or even ahead in general though.

  12. very good learn, i certainly love this youtube-site, keep on it

    It’s laborious to find educated individuals on this subject, but you sound like you recognize what you’re talking about! Thanks

    You must take part in a contest for probably the greatest video on theyoutube. Ill suggest this video!
