Comment on This manhole placement is more than mildly infuriating

  Depends. The cover is resting on the inside lip which prevents moisture getting in. Ie. this cover is actually significantly bigger than the hole it's covering.

  Eg. if this cover is 25x25, but it's covering a hole which is less than 18x18 (c=25.5), it'll be quite hard to drop the cover in.

  The problem is the hole is smaller than the cover. If they were the same size it would fall though

    I think you’re misunderstanding. Yes, it cannot fit in when it’s angled properly to fit into the hole. However, if you angle the plate 45 degrees and lift one end of the plate, it will fall into the diagonally. That’s why manholes are round shaped. There is no angle for a round cover to fall into the hole itself.

      You are right, never mind. I was thinking Pythagorean theorem

  The cover is resting on the inside lip that's smaller than the outside lip, prevents moisture getting in, and probably small enough that this won't actually fall in easily if at all. Something like this:
