How is the total length of a sewer line segment determined between manholes?

The total length of a sewer line segment between manholes is determined by adding the measurements of both stations. This approach utilizes the individual measurements taken at each manhole to calculate the total distance between them. By assessing each station's coordinates or positional data (which typically includes horizontal and vertical components), you can accurately establish the length of the sewer line.

It's important to note that the direct measurement of the pipeline’s slope or average distance between manholes does not provide a precise assessment for total line length since these methods may overlook variations in the actual path the sewer line follows. Therefore, relying on the precise measurements from both manholes ensures that all factors, including elevation changes or bends in the sewer line, are taken into account for an accurate length determination.
