How to Create an InfoSWMM, InfoSewer, H2Map Sewer model from CSV Files

Introduction: InfoSWMM for ArcGIS (Esri, Redlands, CA). InfoSWMM  enables engineers to work more efficiently and reliably with very large and complex network models, thanks to improvements in such areas as built-in 64-bit simulation, enhanced water quality modeling, and batch run scenario management using many of the Arc Map tools developed for InfoWater and InfoSewer.. All operations of a typical sewer system — from analysis and design to management functions such as water quality assessment, pollution prediction, sediment transport and deposition, urban flooding, real-time control, and record keeping — are addressed in a single, fully integrated geoengineering environment. The program’s powerful hydraulic and water quality computational engine is based on the current SWMM 5 version, which is endorsed by the USEPA and certified by FEMA.

An InfoSWMM model can be newly created from a CSV file but it helps to have a background map or shapefile to initialize the Arc Map project. BEFORE initializing your InfoSWMM map Add a data layer using the Arc Map command Add Data. Create a new InfoSWMM project using the same spatial reference as your added shapefile (Figure 1). Import the CSV files (Figure 2) and define the imported variables (Figure 3) followed by an Update Map from DB (Figure 4) which will draw your imported nodes and links on the Arc Map screen. The updated Map will have the same coordinates as the background shapefile (Figure 5). It is important to have the proper spatial reference for your imported data in Arc Map.   This tip also applies to InfoSewer, InfoSurge and InfoWater models as well.

An alternate method is to not use a shapefile to define the extents of your import but to define the Map Extents before initializing your Arc Map Project (Figure 6)  An InfoSWMM model can be newly created from a CSV file but it helps to have an idea of the maximum extents before you initialize the Arc Map project. Use the ArcGIS default and Edit the extents of your future imported network (Figure 6). Import the CSV files (Figure 2) and define the imported variables (Figure 3) followed by an Update Map from DB (Figure 4) which will draw your imported nodes and links on the Arc Map screen. The updated Map should be within the extents of your defined spatial reference (Figure 5). It is important to have the proper spatial reference for your imported data in Arc Map. If you do not have the proper extents then when you update the Map from DB you will have a warning message “The coordinates or measures are out of bounds”.

The imported model has the same coordinates as the original imported shapefile.
