Designing Pressure
Pipe Networks
Now that you have studied gravity pipe networks, it's time to move on to a
different type of pipe design: one that involves pipes under pressure. If you're
unfamiliar with pipe design, you may be surprised to discover that the design
process for gravity and pressure systems is quite different. For this reason, the
AutoCAD ® Civil 3D ® software provides two unique tool sets: one for gravity
pipe design and one for pressure pipe design.
Pressure pipe design most commonly refers to water supply lines but can
also apply to natural gas and sanitary sewer lines. These pipelines provide
valuable utility services to the new residents of the land you're developing and
must undergo extensive design to ensure that they function as intended
and integrate well with surrounding features, whether new or existing.
In this chapter, you'll learn to

Gravity system designs and pressure system designs are quite different and
must be addressed using different tools. For a pressure pipe network design
to be a success, it must meet the following basic requirements:
The bends and curves must be constructed according to industry-
standard fittings and allowable joint deflections.
The pipes must be sized according to specific flows and pressures.
The pipes must be far enough underground to avoid being dam-
aged by freezing or by activities on the site.
