Edit/Create Sanitary/Utility Structure/Laterals

This is an alternative version of Edit/Create Sewer Structure for the design of sanitary and utility networks. A sanitary or utility network is generally made up of pipes and structures. There may be more than one pipe entering a structure, but only one can exit. The network type is set in the Sewer Network Settings dialog, and the default type is storm sewer. When you run Edit/Create Sewer Structure, the program performs differently based on the network type. If you work on a storm sewer network, please refer to the documentation on the Edit/Create Sewer Structure. 

This command construct a graphical representation of a pipe network in active drawing, which contains all your design data, such as pipe and structure data. The following is an network example. The Edit/Create Sanitary/Utility Structure dock dialog is on the left, while the network plan view in the active drawing is on the right with current structure and pipe highlighted. When you modify the edit fields on the dock dialog and click on Apply button, the network plan view will be updated automatically. Furthermore, you are allowed to work on the active drawing while the dock dialog is open. This command doesn't perform hydrology calculation, so no flow data is needed.

Edit/Create Sanitary/Utility Structure Dialog and Dynamic Editing in the Active Design Drawing

1. Dock-Dialog Components

First set up the working environment by running command Sewer Network Settings under Network > Sewer Network Setup menu. Then select Edit/Create Sewer Structure. If you are creating a sewer structure, pick a location in the plan view where you want to locate the structure, otherwise click on an existing structure symbol. After a structure has been located, the dock dialog displays, and the current structure symbol is highlighted in the drawing. Following is an example of the dock dialog.

Edit/Create Sewer Structure

This dialog window has two tabs, Structure and Pipe, which are used to enter structure and pipe parameters. The following is the description of the functionalities of the buttons for designing sanitary/utility network.

Settings: This function performs as same as the Sewer Network Settings command except for the generate settings of setting up the network file and surface file etc. Please refer to the documentation on Sewer Network Settings.

Add: Adds a new structure to the network at the location you pick in the plan view. The just created structure will become the active structure for editing.

Edit: This function allows you to pick an existing structure symbol in the plan view to make the structure active for editing.

Remove: This function removes the structure that you pick, and also removes the corresponding pipes and then reconstruct the network.

Apply: Save the changes of the network.

Up: Moves to the upstream structure and makes it active.

Down: Moves to the downstream structure and makes it active.

Close: Quit the sewer network dock dialog.

2. Structure

The structure data is entered through the Structure tab.

Sanitary/Utility Network Edit Structure

Structure Name: An identical name of the structure in the network.

System Name: A name for current network. All the structures in the same network have the same system name.

Structure ID: This is the ID of a predefined structure in the structure library. The Library button next to it allows you to select or define a sewer structure in the structure library. Once you select the structure, the dimension of the structure are retrieved from the library. Please refer to the documentation of the Sewer Structure Library for details.

Reference CL: The reference centerline is used to locate the structure by station/offset of the centerline points, and align the structure symbol in the graphic. The Select button allows you to select a centerline from either a centerline file or a polyline.
Location: This button allows to relocate the structure by pick a position in the drawing.

Symbol Name: This is the name of the symbol that represents the structure in the network plan view. The Symbol button allows you to select a symbol from a list of symbols.

Symbol Rotate: There are 10 options to rotate the structure symbol for displaying in the drawing.

Symbol Angle: When the Symbol Rotate value is set to Enter Azimuth Angle, this edit field is enabled for entering an angle.

Symbol Size: Three options to determine the size of the structure symbol.

Rim Elevation: The rim elevation for the structure, it's usually the surface elevation.

Depth: The distance between the rim elevation and the base elevation of the structure.

Invert-Out Elev: The invert elevation of the pipe that exits the structure.

Sump Height: The distance between the base elevation and the invert-out elevation.

3. Pipe

The pipe data is entered through the pipe tab. The Downstream/Upstream list contains the connection that exits the structure or the connections that enter the structure, depending on the design direction. The Available list contains all the structures that are not connected to the current structure, i.e. the potential structures that can be connected to the current structure. There is two ways to add a connection. The first one is clicking on the Add button to connect the highlighted structure in the Available list to the current structure. The other one is clicking on the Pick button and then select a structure symbol in the plan view to connect it. If the connection is unable to be performed, a warning massage pops up. By selecting the available structure to Add or Pick the Pipe Connection Wizard dialog will open to allow the user to visualize the connection to be made. See the following section for more information on the Connection Pipe Wizard. The Remove button allows you to remove the highlighted connection from the Downstream/Upstream list.

Sewer Network Edit Pipe

Pipe Name: An identical name of the pipe in the network.

Pipe Shape: The pipes can have four different cross-sectional shapes: circular, box, horizontal ellipse and vertical ellipse.

Pipe Material: There are nine material options.

Pipe Size: The value can be chosen from a list of pipe sizes stored in the size library.

Pipe Size Library: This button allows you to store commonly used pipe sizes. Please refer to the documentation on the Pipe Size Library for details.

Pipe CL: This option allows you to design a non-straight pipe. The pipe centerline should start from one structure and end at the other exactly. If you change the location of one of the structures, the centerline would be deserted and the pipe would become straight.

Manning's n: The Manning's n coefficient is used to calculate the friction loss of the pipe. The Library button allows you to select a Manning's' n value. Please refer to the documentation on the Manning's N Library for details.

Down Invert/Up Invert: They are the downstream invert and upstream invert elevations of the pipe.

Slope: Pipe slope.

Min. Cover: The minimum distance from the surface elevation to the crown elevation all along the pipe, is calculated automatically.

Connection Pipe Wizard

Selecting the available structure to Add or Pick the Pipe Connection Wizard dialog will open to allow the user to visualize the connection to be made. If the normal slope based from the Sewer Network Settings file CAN be created the following dialog box will appear.



Lower Branch Pipe and Use Steeper Slope: This will change the slope of the branch pipe to match the invert of other upstream connection.

 Lower All Branch Pipes By Current Slope: This will lower both inverts and maintain the current slope.

Original Results: This will reset changes made to the original results.

If the normal slope based from the Sewer Network Settings file CANNOT be created the following dialog box will appear and offer other design changes for the connection.

.

Lower All Downstream Main Line Pipes By Current Slope, Add Step Up/Drop At Upstream Main Pipe: This will lower all downstream pipes by the current slope to the branch pipe elevation, therefore creating a step up/drop structure for upstream pipes.

Lower All Downstream Main Line Pipes By Current/Minimum Slope, Add Step Up/Drop At Upstream Main Pipe: This will use the Sewer Network Settings to lower all downstream pipes by the current/minimum slopes to the branch pipe elevation, therefore creating a step up/drop structure for upstream pipes.

Lower All Downstream Main Line Pipes By Current Slope, Steeper Slope At Upstream Main Pipe: This will use the Sewer Network Settings to lower all downstream pipes by the current slope to the branch pipe elevation increasing the upstream pipe connection.

Lower All Downstream Main Line Pipes By Current/Minimum Slope, Steeper Slope At Upstream Main Pipe: This will use the Sewer Network Settings to lower all downstream pipes by the current/minimum slopes to the branch pipe elevation increasing the upstream pipe connection.

Raise All Branch Pipes By Current Slope: This option will raise branch pipes by the current slope

Raise All Branch Pipes By Current/Min Slope: This option will raise branch pipes by the current/minimum slope.

Raise Branch Pipe At Downstream Side: This option will raise the downstream invert of the branch pipe.

Original Results: This will reset changes made to the original results.
