Items can be added to the plan and connected individually, or drawn as a connected Treatment Train using the Add Train tool in the Build menu. The former approach, adding items individually, will be used here. The treatment train begins with the Inflow Area of the Developed Area that drains to a Bioretention Stormwater Control (SWC), from here the site runoff is conveyed to a Dry Pond.
Select the Inflow Area - Dev.dwg file from the Tutorial Files folder. Click Next.
|Note that this file is included in the IMPERIAL [US Units] model files zipped (*.zip) folder.|
Move the pointer to the location on the site where the SWC will be installed and use the left mouse button to draw the outline of the Raingarden (similar to the outline shown in the figure below). When you are done drawing the polygon, use the right mouse button to end the drawing action.
|The SWC outlines can be redrawn at any point by right-clicking the SWC and selecting Replace Outline.|
Right-click the northern edge of Raingarden (where the under drain will exit the SWC and connect to adjacent MH) and select Add Connection, choose the Standard Pipe template. Then left-click the adjacent Manhole.
|Note that the Standard Pipe template consists of a 12-inch diameter pipe with roughness of 0.013. This and other templates can be viewed by browsing to File >Templates.|
You can continue clicking to connect the manholes and then connect into the Dry Pond.Then add a Standard Pipe between the northern MH and the side of the Dry Pond SWC. The result should look as shown.
|If you lose the drawing mode, right-click the MH and perform the same action to connect a 12 inch pipe to the northern manhole.|
We currently only have the underdrain from the Raingarden SWC outfalling into a 12 inch pipe and into the adjacent MH. We need to specify the high flow bypass weir for this facility. Close the Profile view.
Note: You can turn off labels on Plan using the Display Settings.
Click to select the Raingarden stormwater control. Right-click the north eastern side of the SWC and select Add Connection. This time, select Bypass Trapezoidal Channel. When you connect this to the adjacent MH, you will see inlet options for the manhole. Either the existing inlet or a new inlet can be selected. As we are not restricting inflow into this MH from either connecting pipe, we can select the existing inlet. Press the Esc key to end drawing connections.
|If the Inlets and Outlets fall outside of the SWC, the Inlet and Outlet icons will disappear automatically and the links will connect directly to the SWC icon. The Inlets/Outlets are not deleted, only removed from the graphical view, they can be redrawn by right-clicking the SWC icon and choosing the Specify Inlet/Outlet Location command.|
