190 | Chapter 14 Designing Pipe Runs
Overview of Designing Pipe Runs
The Pipes menu in contains commands to design and draft pipe runs of
storm water or sanitary sewer collection systems.
You can start a design by drawing conceptual pipe runs, represented by single
lines, or you can import predefined pipe runs into the drawing. You can use
terrain models to obtain elevational data for the pipe runs and you can asso-
ciate a pipe run with a roadway alignment for horizontal location data. After
you have sized and configured a pipe run, you can draft finished plan and
profile pipe runs with customized labels, node structures, and graphical pipe
designations.
You can use the Pipes commands to
■ Design and draft sanitary and storm water sewer systems in both plan and
profile views.
■ Perform flow, velocity, depth, slope, and other types of analyses to satisfy
a variety of design conditions using the Pipes Run Editor.
■ Determine hydraulic and energy grade line elevations for a system.
■ Size the pipe segments and adjust run variables with the Pipes Run Editor.
Some terms used in this chapter are described below.
Node An intersection of individual pipes, or the end of one
individual pipe, in a defined pipe run. In a sanitary
sewer design, the node is typically represented by a
structure such as a manhole.
Pipe An entity that connects two unique nodes.
Run A collective group of pipes and nodes. A pipe run has a
minimum of two nodes connected by a pipe.
Structure The physical definition of a node, such as a catch basin,
manhole, or an item at the end of a pipe.
