Designing Gravity
Pipe Networks
With the completion of
parcel design, you're ready to move on to another
major area of design: pipe design. As a designer, one type of pipe design that
you must address is the safe and efficient collection and conveyance of water
that falls on a site during a rainstorm. This type of pipe design is part of a
larger design process called
stormwater management
. Because the develop-
ment of land often involves turning absorbent surfaces (soft grassy soil, trees,
and forest floors) into impervious surfaces (pavement, concrete, and asphalt
rooftops), rain that falls on a developed site will travel farther and much faster
before it's absorbed when compared to rain that fell on the site before it was
developed. This water on the move can cause erosion or flooding, so it must
be safely collected and placed in surface channels or underground pipes. The
pipes and channels then carry the water to a safe place where it can be dis-
charged without doing harm.

software is divided into two
types: gravity networks and pressure networks. Because the performance
requirements for these two types of systems are so different, the approach to
designing and constructing them is also quite different. In this chapter, we'll
begin with gravity pipe network design.
