Install
pip install swmmioAbout swmmio
Where PySWMM drives the engine, swmmio handles the model files: it parses INP models into pandas DataFrames and GeoDataFrames, lets you edit networks programmatically, generates versions and scenario variants, and renders quick network visualisations. Comparing two model versions element-by-element — painful in a GUI — is a one-liner.
For utilities managing large SWMM models or consultants running scenario matrices, swmmio turns model administration into reproducible code. It composes naturally with PySWMM in the same script.
