How do hotel and Apartment sewage pipes connect between rooms?

So there my toilet right. Its pipe width is whatever is normal. Does it connect to a bigger diameter pipe?

I’m assuming all the individual rooms poop pipes empty to the same big poop pipe.

If I make an extra big deposit at the poop bank and my neighbor does the same, but I flush just a few seconds before my neighbor, could my poop collide with theirs and clog their toilet?

Is the big central highway poop pipe always full of water?

Sorry for all the questions. I’m counting on you my pipe people

Edit: Oh yeah different floors. Does each floors big poop pipe empty to the same vertical poop pipe?

If I take a poop (in a toilet) on top of floor of a skyscraper, how fast does my poop plummet to the earth?

    The reason it wouldn’t collide has something to do with an element of the network of pipes that I haven’t mentioned yet.

    First, all pipes have a pitch or slope. That’s to ensure that the flow only goes in one direction. Secondly, pipe joints have a “sweep” to them, meaning the joint directs the the waste to go in a certain direction when intersecting another pipe.

    The fitting in the image below is called a sanitary wye(Y). Imagine that your toilet or sink would be the source of the waste and would be connected to the 2" side. You can see which direction this would direct the waste and each connection to the trunk would be directing the waste in the same direction. For this reason, your flush would never collide with another, instead it would be like you both would be speeding along in the same direction and just kind of blend together if they happened to meet in the pipe at any time.

    Pressurized plumbing does not have these sanitary features, they just have hard angles with no sweeps because the pressure is what pushes the water to your faucet. Drain lines lack this force so everything is handled by pitch and flow guidance in the form of these joints.

      So technically if I have the right fishing gear, I could turd burgle my apartment neighbors without leaving a trace? Like a poop ninja?
