Impressive Storm Sewer System / Saitama, Japan
To avoid floodings on typhoon season, the city of Saitama in Japan features an impressive storm sewer system. Its construction started in 1992, and its composed by giant concrete silos (65m tall, 32m wide) connected by 6.4km of underground tunnels 50m below the surface. It also has a giant tank: 25.4m tall, 177m long and 78 wide, with 59 concrete columns.
This impressive structure is opened for tourists. More pictures and videos below. Be sure to check out the truck being lifted through the sewer!.

reminds me of the dwarf-city “khazad-dûm”
my first thoughts too. all the workers should be running around in chain mail and grow furry beards…
The Underground City was called Moria
same thought on khazad-dûm! @Alban Dwarf name…Elven name is Moria and also called Darrowdelf.
igualitos a los de santiago para evitar las inundaciones de las calles
Simply beautiful!
Great stuff. Had this on RedRuin a few years back:

Would be nice to take a tour sometime.

Anyone else reminded of the silent hill movie?
A pity this place can’t be used as an event hall or something… can oyu imagine? That’d be great
reminds me of lord of the rings to me
reminds me of evangelion
Wow! That’s cool!
My hometown of Kristianstad, Skåne (Europe) could use something similiar, as it is situated two-three metres below sea level. Though, there is no foundation below the city to build in. Just pure mud. It’s a wonder they managed to build the city once upon a time. At that time they built the city pretty much on two giant rafts, floating in the middle of a swamp, centuries ago. Damn stupid location.
Normally I don’t leave a comment but your post was excellent.
Finally! A place for the apocalypse’s sewer level! XD
Great project.
The Great Realm and Dwarven city of Dwarrowdelf
english translation of section..pls?
Igualito a las cisternas de Estambul!
reminds me of half life 2
It actually reminds me of the first resident evil movie the ‘train station’ to the ‘Hive’ which was a real underground train station in europe somewhere i believe
This reminds me more of mirror’s edge… most likely because there’s a level based off of these :P
Exactly, Mirror’s edge! a little more difficult than in the game though.

일본의 경우 수도권에 지하댐을 건설하여 집중강우에 대비하고 있습니다. 우리도 이러한 대책에 대한 검토가 필요하지 않나 싶네요. Storm Sewer System / Saitama, Japan: http://bit.ly/aN7M2Y
