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.
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.
