Lateral Design Overview

Lateral design is available in both the storm sewer and sanitary sewer design programs. A lateral pipe is very much like a regular pipe in sewer network. A lateral is the underground pipe that connects a residence or business to the main line pipe. The lateral connection has a property of offset elevation relevant to the mainline sewer invert at the point of connection. Both the cleanout and connection can be either a box or circular structure. The lateral data is stored in the main network / current network file, although designed using a different command. A prerequisite for Lateral Design the user must have completed either a Storm Network or Sanitary Sewer Network as the main line, and set the file as the Active File to be used in the Sewer Network Settings dialog box.

Create Lateral Structure

There are two options to locate a Lateral Connection Point. Pick a Structure, this can be any structure created in the main line file such as a Manhole or Inlet, or Pick a Pipe within the Main Network.



 

The Pick a Structure allows the user to select a structure within the Main Network File and opens the following Docked Dialog. This dialog box works similar to the regular pipe in sewer network. By hovering the mouse over the icons at the top of the dialog box the user can see the command associated with each. Starting from left to right the commands are as followed Add Connection, Add Cleanout, Edit, Remove, Up, Down, Save, Exit, and Help. The Structure Tab gives the user information of the selected structure. The dialog box specifies the downstream and upstream manhole connections as well as the station along the main network pipe measured from the downstream structure. The Connection Height allows the user to specify the entrance height of the connection on the main network structure. Depending on the type of the connection point some of the dialog box will only supply data while others may be edited. In the following example we selected to connect to a structure, therefore data present related to the actual manhole with only the connection height available for editing.





When the Pick a Pipe option is selected other fields in the docked dialog box are available for selection allowing the user to specify a Structure Name, System Name, Description, Symbol Rotate, Symbol Angle, and Symbol Size. Rim Elevations and Depth are calculated and the downstream and upstream manholes shown. The user is given the downstream station for the connection that can be adjusted if desired, as well as a connection height.



The Pipe Tab of the docked dialog will display the pipe lateral data once a cleanout location is located. This is the same for both types of connections. This dialog box allows the user to design pipe data associated with the lateral pipe, and is used to assign Pipe Name, to assign Downstream Connections, Pipe Material, Pipe Shape, Pipe Size, set the Inverts Upstream and Downstream, or to adjust the Pipe Slope and which invert to Update. The properties box at the bottom displays other properties and values assigned.



The Profile Tab provides a visual aid showing the lateral pipe and other associated pipe crossings for consideration during design. A Vertical Exaggeration can also be applied for an increased aid.


Edit Lateral Structure

Editing a lateral is similar to a regular pipe. The invert elevation of both ends of the lateral can be modified the same as a regular pipe. To edit a lateral structure the user can select from the following image in the network menu or double click the lateral structure to edit. After selecting the docked dialog box opens and edits can be made on the Structure or Pipe Tab.



The Spreadsheet Sewer Editor can also be used to review and edit lateral connections. Toggle the Edit Lateral Line to revise or adjust laterals.





With the toggle on the user Selects Lateral Main Pipe Line, and the laterals associated with that main line pipe can be edited.
