Importing SWMM5 Network Data to SWMM Networks

There are two ways in which data can be imported from a SWMM5 text file into a SWMM network:

• Using the Network's menu Import | Model from SWMM5 text file option to import the data to SWMM network objects and model parameters.
• By importing the following database items:
  • SWMM Pollutograph
  • SWMM Time Patterns
  • SWMM Run
  • SWMM Climatology
  • Events - Rainfall, Levels, Inflows, and Regulators
  • Label lists
  • Selection lists
  • Model group - when importing as a model group, data will be imported to SWMM network objects and model parameters as well as the database items listed previously provided the relevant data is contained in the SWMM5 text file.

The same SWMM5 text file can be used as input for both import methods.

For details of importing database items, see the Working with Database Items topic.

To import network data from a SWMM5 text file to ICM SWMM network objects, model parameters and database items:

1. Open the SWMM network to be updated.
2. Select Import | Model | from SWMM5 text file from the Network menu, and a Windows File Open dialog is displayed.

   In this dialog:

3. Enter the path to the text file to be imported in the File name box.
4. From the Encoding dropdown list, select which encoding system is used in the text files to be imported. Currently supported systems are ANSI, UTF-8 (default) and UTF-8 BOM.
5. Click OK to import the SWMM5 data.

   When the import process is complete, a log file, which contains any conversion errors or warnings, is displayed.

For details of the SWMM5 data sections imported and conversions made by the importer using either import method, see the SWMM5 Conversion Notes (SWMM) topic.
