  2. Have an option for pipes to automatically connect soffit to soffit at MH's

    Where you have different pipe sizes connecting at a MH good practice is for the connections to be made "Soffit to Soffit", it would be usefull if this could be done automatically and would remove the need to manually change each connection to take this into account.

  3. Identify foul and surface water with different colours

    There should be an option in the display settings to change the colour of foul and surface water networks.

  4. Model a sag inlet with an allowable depth of ponding

    I need to be able to model a sag inlet accurately within InfoDrainage. I would like to design these inlets so that there is an allowable ponding depth, and then any volume that exceeds that depth is applied to the surface as a 2D overland flow.

  6. Levels for "junction" items

    When using the "junction" connection item, it always sets the cover level on the item to 0. This is true even if you had a manhole that had a proper cover and invert level input, if you switch the manhole to a junction (for instance because you don't want to falsely include the volume of a manhole that isn't actually there) then it jumps the cover to 0 and the invert to -1.5. (It might not do it if you have a ground model in, not sure, I usually work without).

    You can fix it by going across to the…

    Thank you for the suggestion and thanks to those who commented and voted. 


    In InfoDrainage, junctions are used as nodes without volume to enable modelling a Y or T junction, or it could be a point in the middle of a culvert that is getting wider for some reason.


    You are right; when the pipe US and DS cover levels are 0, and the junction has a level of 0, the model will find no way to design the system and run the design wizard. Therefore, to address this, we've implemented a warning message that will stop users from proceeding with the design if they have junctions and the associated ends of the pipe have a 0 level (that hasn't been overwritten). Users can still use the level 0 but they need to overwrite the default 0 to proceed. The warning message will be made available to users in a…
