Chapter 14

Storm and Sanitary Analysis

One of the trickiest and most controversial parts of a civil designer’s job is determining where water and wastewater will go in a site. Civil 3D offers a variety of tools for designing and analyzing the hydraulic and hydrology portions of your project. Hydraulic calculations for pipe design takes into account many factors that influence the end product. Hydrology is part science and part art, with a dash of voodoo. Luckily, Storm and Sanitary Analysis (SSA) is here to help you sort it all out.

SSA is a separate program that launches from the Analysis tab in Civil 3D or from the Autodesk folder off of the Windows Start menu. This is the portion of the product that can compute site runoff, pipe sizing calculations, and design pressure pipe systems.

In this chapter, you will learn to:

• Create a catchment object
• Export pipe data from Civil 3D into SSA
