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.

SteveOh, dude, finding the invert level of a manhole is like finding the meaning of life - you just gotta look down. Basically, you grab a measuring tape, drop it down the manhole, and measure the distance from the top of the manhole to the invert. It's not rocket science, just manhole science.
Well, honey, to find the invert level of a manhole, you'll need a measuring tape, a level, and some good old-fashioned common sense. Measure the distance from the manhole cover to the bottom, then subtract that from the total depth of the manhole to get the invert level. Just make sure you don't fall in while you're at it!
Ah, finding the invert level of a manhole is a beautiful process, my friend. Simply measure the depth from the manhole cover to the bottom of the manhole using a measuring tape or a level. This will give you the depth. Then, subtract this depth from the height of the manhole to find the invert level. Remember, there are no mistakes in finding the invert level, only happy little accidents.

What is the invert level for manholes and inspection chamber?
the lowest level of outgoing orifice where there are numerous inlet & out pipes connecting a manhole.
How do you determine invert level?
invert level =high level - the reading - the diameter of pipe
Definition of Invert Level?
The invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. Conversely, the crown level is the highest interior level, and can be considered the "roof" level

What is the difference between invert level and reduced level in surverying?
In surveying, the invert level refers to the elevation of the bottom of a drainage or sewer pipe, indicating the lowest point where water can flow. In contrast, the reduced level (RL) is a reference elevation used to simplify measurements, typically expressed relative to a benchmark or datum point. While the invert level is specific to drainage systems, the reduced level can apply to various points on a site for overall topographical analysis. Both are crucial for ensuring proper drainage and site grading.
