Open the file XPD_US_Advanced_Tutorial3.xpdx or continue working from your previous file.
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 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.
Now we are going to add the drainage network. Turn off Snap on the Plan ribbon. Under the Build ribbon, select the Add Stormwater Control option and then the Raingarden SWC. 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.
Under the Build ribbon, select the Add Network option and then select Standard MH from the Next Item dropdown. Move the pointer to the location on the site where the first manhole will be installed and use the left mouse button to place the manhole. You will notice that the software automatically assigns the inflow area to the junction when it is placed in Plan View. Next select Standard Pipe from the Add Connection dropdown and continue placing the manholes as shown below. Press the Esc key to end the run of pipes.
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.
We currently only have the underdrain from the Raingarden SWC outfalling into a 12" pipe and into the adjacent MH. We need to specify the High flow bypass weir for this facility. Close the Profile view.
Set the criteria as seen below. Further information about the Analysis Criteria dialog and the Rainfall Manager can be found on the given Help topic Analysis Criteria.
