The General 1 tab fields enable users to specify the type of connection for the service lateral, as well as additional connection information, structure information, the installation date, and the source of the data. Several fields in this tab have special functions, which are described below:
Field Name |
Special Function |
Dist from Structure |
Records the distance, in feet, from either the downstream or upstream structure to the service connection. Note: The data in this field is used to calculate the Dist from DS Structure field. |
Measured From |
Indicates whether the distance recorded in the field above was measured from the upstream structure to the downstream structure (US to DS) or from the downstream structure to the upstream structure (DS to US). Note: The data in this field is used to calculate the Dist from DS Structure field. |
Dist from DS Struct |
Reflects the distance, in feet, from the downstream structure to the service connection. Note: This field is automatically calculated by the system and is based on the information in the two previous fields. |
Angle from Main |
Stores the direction of the lateral from the sewer main, as measured with the downstream structure as the 0 axis. Looking at the downstream structure with the lateral perpendicular to the sewer main on the left, the angle is 90 degrees. If the lateral is perpendicular on the right, the angle is 270 degrees (or -90 degrees). This is a direction relative to the sewer main; this is not a cardinal direction. Note: This field is used by the Sewer Toolkit to export service laterals. |
