Add check dams as a feature for swales

Add a check dam setting with height, notch weir and interval settings to simplify modelling swales on sloping sites. This avoids having to model several sections of swale in order to use the available storage.

Import Civil 3D surface directly to Infodrainage

Importing a Civil 3D surface directly would eliminate any errors in the conversion process, ensuring triangulations are accurate and surface boundaries are observed

Improved catchment area import

Importing the catchment areas from cad is an extremely useful feature which would save hours of time, however, it does not work with all the areas and specifically not those with curved lines (most of the time). I think if infodrainage could impor...

Horizontal orifices as an outlet type

HydroCAD offers a horizontal orifice control outlet type that is very commonly used for detention pond outlet types in the US. Please include this as an outlet type so we can transition from HydroCAD to InfoDrainage.

Option to remove the 1m access chamber from cellular storage design

For a start, its not clear that the software actually does this, except one line in the help. So would probably be a good idea to make that clear. But the main issue is that I either need to mess with the volume or the porosity to make the volume ...

Enhance STW integration into Civil

More raw data from STW Infodrainage features into Civil 3D for more design setup. Swale and Pons as an example come in as rough feature lines and very rough surfaces. Data information with it would be great.

Add STM as an import option from SSA

With SSA going away for 2026, having a more direct transition with an STM file would be nice.

Outfall Details input window

The Outfall Details input window is of fixed size, in width and height. This makes using the "Level Curves" tab difficult, as in order to select a set of different hydrographs for different storm events, one must constantly scroll right and down t...

Would it be possible to include longitudinal gradient (slope) to attenuation tanks please? At the moment it appears that software assumes that these structures are constructed flat whereas in real life these could be constructed with a gradient (slope) from the upstream end towards the outlet.
