    A pity this place can’t be used as an event hall or something… can oyu imagine? That’d be great

    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.

    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

    While doing simple tips such as implementing a clean as you
    go policy and other practical self-service tips in the workplace,
    you will still need to have janitorial services in Chino Hills CA in your office.
    With their experience, they may also reduce the budget required for installation of plumbing fixtures.

    Or you can even use a continual pump for that water to recycle on its own.
