Section Feature Class

A section is a wastewater channel or pipe between network points. Sections are the only standard line feature of a wastewater utility model.

The data model stores both real pipe geometry and the network topology, which is a more abstract view. Physically, a pipe runs between two manhole structures and a manhole has a certain diameter. Topologically, a section runs from manhole (center) to manhole (center).

Use intermediate points to add detail so the line from manhole to manhole is more accurate.

Note:

In the wastewater industry model options, you can enable manhole/section validation. See Set Wastewater Industry Model Options.

The manhole/section validation checks the consistency of the bottom height in the section and manhole feature class. In the feature class form, attributes that do not match are highlighted, and a tooltip explains the inconsistency.

Wastewater data model: Section between two manholes. Physically the section is represented by a pipe that runs between the manhole structures.
