This chapter describes three
fundamentals for using the Model
DG511/711 to install gravity flow
pipe; they are Grade, Elevation,
and Line, otherwise known as
G-E-L.
To install gravity flow pipe, the
pipe is set to a percentage of
Grade that has been determined by
some engineered plans. The gravity
flow pipe is designed to be set to
some engineered Elevation.
Finally, the gravity flow pipe will
be installed between two designed
points, therefore defining Line.
