The Manhole happened in 1988.
30ft
The Manhole was created in 1988.
Because it is a hole in a street meant for workmen to climb down to check the sewers. A hole for a man is a manhole.
If they were rectangular they could fall down the manhole.

Rim, on a manhole, is the elevation of the top of the cover on the manhole. In a roadway the rim will at be final grade, in grass they can be sumped, flush or stick up.
The manhole is at Main Street by the Muesuem.
Get a crow bar and you can easily lift it out. Then you can do whatever you want in the manhole. Also manhole covers scrap at a junk yard for about 10 bucks.
Manhole covers are used for many things. Manhole covers are used to cover up holes in the ground where sewage can be found in order to protect people.

To find the level of invert level of a manhole, you need to use a level or a theodolite to measure the elevation of the invert, which is the lowest point inside the manhole where the pipes meet. First, set up the level or theodolite at a known benchmark or reference point nearby. Then, measure the vertical distance from the benchmark to the invert level of the manhole. This measurement will give you the invert level of the manhole in relation to the benchmark's elevation.
Yes, the depth of a manhole can be calculated by subtracting the invert level (the lowest point inside the manhole) from the cover level (the ground level above the manhole). This difference gives the vertical distance from the cover to the invert, which represents the depth of the manhole.
