Why horizontal distance on Gravity Sewer Profiles?
Why horizontal distance on Gravity Sewer Profiles?
(OP)
I've wondered this for a while. Why do most engineers label horizontal distance on sanitary sewer profiles rather than the slope distance? I know that if you label the slope distance it will actually be the actual length of pipe, but it won't match the stationing. But is it really necessary for them to match?

Assume the distance manhole to manhole is 180 m, slope is 1.5%, so the actual length along the profile is SQRT(180^2+(180*1.5%)^2)=180.020 m. Do you think there is a big problem with 180 m and 180.020 m?
Usually only horizontal distance is used.
