Sewer Discharge Controller Inspection

Creation Mode: Assign to Sewer Discharge Controller (not allowed on scenarios with start time > 0)

Purpose and Effect: This action allows you to extract simulation properties of a sewer discharge controller. A discharge controller is a flow control device used to regulate outflow from storage units or other nodes in a sewer network. It models complex dependencies between discharge and the hydraulic conditions at the inlet and outlet nodes—cases that cannot be accurately represented using weirs, pumps, or orifices. These dependencies are defined through either functional or tabular rating curves. The Action Tool Panel provides control over the display options, which currently include discharge and a verification plot.

Hint: The Action Tool Panel provides the option to select all discharge controllers for inspection, which can be used for finding their locations in a large sewer network.

Display Options

There are different Visual Presets available in the Sewers category for the display of the sewer network.

The preset Sewers: Default allows you to select individual discharge controllers for inspection.

The preset Sewers: 3D Meshes allows you to navigate under the terrain to get a clear view of the sewer network.

Inlay Plot

Inspection labels offer the option to display an inlay plot for verification purposes. This plot shows the discharge in relation to the relevant inlet and outlet conditions. The expected rating curve is shown in gray, while the simulated operating points appear as blue dots. Ideally, the blue dots should closely follow the gray line, indicating that the simulation matches the defined control behavior.
