    YSK: manholes are dangerous. Never mind the nastiness and falling hazard. Many are cast-iron and because of the rust, the interior can be a low-oxygen environment. And that’s not the only way the air can be too fouled to breathe safely.

    If you’ve ever seen professinals entering manholes, they’ll be using a ventilation system to ensure fresh air and safety.

    EDIT: this isn’t just about breathing, sewer gasses can be fire/explosion hazards too.

      Its not so much iron as it is all the organic matter that gets run into most drainage systems that decays and consumes oxygen while doing so.

      Some guys did use this here while searching for ancient stuff, one died while 2 other escaped. It looks like an old woman was giving them info on where the ancient stuff are, which was wrong. It turned out, she was wrong.

          Even when that was common, there was a gutter that ran along the sides of the streets. People wouldn’t just dump shit in the middle of the road, they’d pour it in the gutter and the rain would wash it away.

          Still not the best thing ever, but it’s not like people had to wade through ankle-deep piss and shit just to get to the store…

        Yeah, it’s a wild idea, but the number of lives they’ve saved and extended far outweigh any danger. Sewer systems might actually be what increased average human lifespans more than almost anything else in history.

    The time travellers have started arriving to witness the Great Collapse.

    Due to the nature of time travel, portals through time can only be opened in an unobserved place. Sewers are just the places most likely be go unobserved, they don’t even bother putting security cameras down there most of the time…

    Perhaps they’re simply disgraced paranormal investigators following up on reports about pink slime that comes out of the pipes?

    The NYPD, to make sure there was not a threat to the public, sent their highly trained Emergency Services Unit officers into the sewer system

    Taking the piss, surely. Good thing the actual experts went in.

    the city Environmental Protection Department, which manages the system, also went in

    A witness snitch* reported seeing eight people remove a maintenance hole cover near McDonald Avenue and Colin Place in the Gravesend neighborhood of Brooklyn.

    Speaking to NBC New York, witness snitch* Aki Jakupovic said: “Three random guys walking around in a strange suit, open the sewer, go in like Ninja Turtles.” Surveillance footage obtained by NBC New York showed the men carrying flashlights and wearing hip waders. “I was looking at them, they were looking at me, you know, I could tell they were up to no good. They went in there, closed the cover, like, you know, they were never here,” he added.
