Storm Sewer and Analysis (SSA) Error

Hello autodesk community,

I am a senior at my local ABET accredited university. I am using SSA for my Hydrology class to prove a mock project would meet our city/counties standards.

While running an SSA report, my group received the following error message 11 times (I assume for 11 pipes):

WARNING 008 : Elevation drop exceeds length for Conduit L-Pipe 10.0.

I have only two or three pipes run at 7%, as I know it’s good to minimize the slope where possible. If you would be so kind to help me with the conceptual part of our error, it would mean a lot.

Thank you so much!

@aegan4 ,

This a question for the Civil 3D forum.

Maybe this will provide some help:
