How do you calculate the invert elevation of a manhole?
Invert elevations can usually be found directly on as-built drawings of the sewer facility. The simplest way to calculate an invert elevation of a manhole is to measure the depth of the manhole from the surface to the pipe invert. The invert elevation equals the ground or rim elevation minus this depth. If you do not know the rim elevation or invert elevation, a surveyor must measure the invert and/or rim elevation with reference to a nearby elevation benchmark (see: http://commons.wikimedia.org/wiki/Image:Elevation_Benchmark.jpg). Also, upstream and downstream invert elevations in a manhole typically differ by about 0.1 feet.
How deep are manholes?
Manhole depths can vary depending on their purpose and location. They are typically designed to provide access to underground utilities or sewer systems. The depth of manholes can range from a few feet to over 30 feet, with the typical range being 10 to 20 feet.
