--- title: "(USA) Advanced Chapter 3 - Layout Treatment System" canonical: "https://help.innovyze.com/space/infodrainage2020v2/16416855/(USA)%20Advanced%20Chapter%203%20-%20Layout%20Treatment%20System" format: markdown --- | **File/s needed: ** | | --- | | Click to download . | 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**.  1. Open the file **ID_US_Advanced_Tutorial_Ch3.iddx **or continue working from your previous file. 2. Make sure you are still working in the **Developed** Phase.> Macro (inline-media-image) > Macro (inline-media-image) 3. Right-click on the Inflow Area and select **Change Template**. Choose the **Urb-Res-Dev** Template and rename the area. Click **OK**.> Macro (inline-media-image) 4. Double-click the inflow area (or right-click and then select **Edit**) to edit the Developed inflow area. Note the high percent imperviousness and shorter time of concentration. No changes are required due to the use of the developed landuse template, though the calculators could be used for assistance when making updates to **Curve Number** and **Time of Concentrations** values.> Macro (inline-media-image) 5. 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. 6. Under the **Build **ribbon, select the **Add Stormwater Control** option and then the **Dry Pond** SWC. Move the pointer to the location on the site where the Dry Pond SWC is installed and use the left mouse button to draw the outline of the Dry Pond SWC (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. > Macro (inline-media-image) > Macro (inline-media-image) 7. Under the **Build **ribbon, select the **Add Network** option and then select **Standard MH **from the **Next Item** drop-down menu. 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** drop-down menu and continue placing the manholes as shown below. Press the **Esc** key to end the run of pipes. > Macro (inline-media-image) > Macro (inline-media-image) 8. 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. > Macro (inline-media-image) > Macro (inline-media-image) 9. Then add a **Standard Pipe** between the northern MH and the side of the **Dry Pond **SWC, choose the **Outlet** from the radial menu when it pops up. The result should look as shown.   > Macro (inline-media-image) 10. To understand what elevations were adopted and how well the treatment system connects, right-click the **Flow Paths** item at the bottom of the **Tree View** and select **Add** (or alternatively by right-clicking the **Raingarden** and select **Add Flowpath/Profile**) then select the **Raingarden** icon and then click the **Dry Pond** icon. **Hit the Esc key** in order to stop tracing.  > Macro (inline-media-image)    > Macro (inline-media-image) 11. Right-click the new **Flow Path** and select **Show Profile** (alternatively, select the **Flow Path** under **View, Profiles**) to display a profile of the flow path.> Macro (inline-media-image) > Macro (inline-media-image) 12. 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. 13. 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.  > Macro (inline-media-image) > Macro (inline-media-image) 14. To view the newly added Channel in Profile a second flow path will need to be drawn. Right-click the **Flow Paths **option, select the + symbol and select the **Raingarden** icon and the **Dry Pond** Icon. Since the previously traced flow path follows the underdrain of the Bioretention system, this time select the **Bypass Trapezoidal Channel** when prompted. > Macro (inline-media-image) 15. Once added, right-click the newly added **Flow Path (2)** and select **Rename**. Change the name to **Bypass Route**. > Macro (inline-media-image) 16. Right-click the Bypass Route and select **Show Profile**.> Macro (inline-media-image) 17. We can easily see the bypass channel is not at an appropriate elevation, double-click the **Connections** option within the Tree view to open the Connections form. > Macro (inline-media-image) 18. Edit the** **Bypass Channel** Levels **to be as shown, we will also update the Raingarden.  Upstream Cover Level: **1853** ft; Upstream Invert Level: **1852** ft. > Macro (inline-media-image) 19. Click** OK** and the Profile view will be updated. Close the Profile. 20. We will now update the elevation of the SWC to match.** Edit** the **Raingarden** SWC by double-clicking the **icon** (or by right-clicking and selecting **Edit**). Use **Click to Show Image(s)** in order to show a diagram of the Stormwater Control or to view various real world photos of this facility. The **Depth **and **Side Slope** are set in the template and the levels and area are calculated from the surface data (which has been pre-loaded in this model), they may also be defined by the user. The values may differ slightly depending on exactly where you have clicked during the Build options.   > Macro (inline-media-image)   21. Manually set the **Exceedence** level to **1853.0**. Note the red text designating a manual input. Switch to the **Outlets** tab.> Macro (inline-media-image) 22. Go to the **Outlets** tab. Change the name of outlet (1) to be called **Bypass**, and then change the outlet type to **Weir**. Set the **Crest Level** to **1852** (one ft above the base elevation) and set the Width as **1.0** ft as an initial configuration. > Macro (inline-media-image) 23. Click **OK** to close the **Raingarden**. 24. **Edit** the **Dry Pond** SWC. Note by using the template, we have a 5 ft deep pond with a top area automatically set based on how the outline was drawn. The base area needs to be set. Use the **Sizing Calculator** and select side slope, input **0.5** ft/ft (1:2 slope). We will maintain the Top Area. Select **OK** and note how the depth-area-volume table and associated schematic have been updated.> Macro (inline-media-image) 25. Select the **Outlets** tab, select the + button and from the available **Outlet Types** select the **Multiple** option. As is common for a Pond SWC, we will have a minor event **orifice** outlet as well as a major event **weir** control.> Macro (inline-media-image) 26. We will be using the pond to control the initial runoff by allowing infiltration. This will help us achieve Runoff Reduction and prevent the Water Quality event discharge from leaving the site. Therefore add 1ft to the Invert Level automatically picked up as the Base Level of the Pond. This will place our outlet control 1 ft above the base preventing any discharge until that depth is reached. > Macro (inline-media-image) 27. Then select the **Edit** button above the depth-outflow table. Select the **+ **icon, select **Orifice **and **Weir** from the list.> Macro (inline-media-image) 28. We could manually enter some starting values for the Orifice and Weir or we could use the wizard calculator to help. Use the **>** button next to the **Control List** table. Enter the following design depth-flow values into the wizard calculator. 1. Orifice: **1** ft Design Depth; **0.9** Design Flow 2. Weir: **3** ft Design Depth; **3.2** Design Flow > Macro (inline-media-image) 29. Click the calculator button **Solve for displayed controls**. Click on each row of the Control List table to see the results. 0.5 ft has been calculated as the Orifice diameter and 0.2 ft as the Weir width. 30. Click **OK** and see the **Depth – Outflow** table populated.> Macro (inline-media-image) 31. Click **OK** to close the **Dry Pond**. 32. Now that the Treatment Train is laid out, you can review the **Analysis Criteria** and **Rainfall** set up by browsing to the **Analysis** ribbon and selecting **Analysis Criteria**. > Macro (inline-media-image) 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**](https://help-innovyze.atlassian.net/wiki/spaces/infodrainage2020v2/pages/16417321)**.** 33. Run the simulation by selecting **Go** under the **Analysis** tab. > Macro (inline-media-image)
