  1. Automatic M5-60 and R values based on Location

    Most models are built on surveys that are on National Grid Coordinates. It would therefore be good for the rainfall data to automatically generate M5-60 and R values based on NGC for the site with the option to click Map and reposition if necessary.

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


    FSR is an outdated rainfall method which was developed in the 1970s, this is why various LLFAs around the UK are now rejecting drainage statements submissions when FSR was used as a rainfall. This is one of the reasons why we would be hesitant to invest into investing more time into this. We are currently working on FEH22 implementation which will be made available to UK customers in future releases of the software.


    However, FSR has a 1km2 resolution, therefore, you can still get the exact site accuratley by hoovering over the map and keeping an eye on the coordinates on the top-left corner (see screenshot). Take one coordinate from your site and use the first three digits from the easting and the first three digits from the northing to establish the exact location on the FSR…

  2. Velocity and proportional velocity to be shown on Tables

    When designing sewers a critical design criteria is the pipe velocity when full or at design discharge rate. It makes designing sewers quite iterative without this included

    In order to get rid of the dendritic numbering system that was in MicroDrainage which prevented users from modelling bifurcation, we had to introduce the design wizard rather than an optimise button that looked at the whole system. This means that users will have to run a design wizard to check the velocities. However, we've introduced various flexibilities for turning on and off design criteria parameters which will make these iterations easier.


    Does the above address your suggestion?

  3. 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. Sum of contributing areas in design tables

    Add a column to the "Junctions" design table when Inflow/Catchment Areas are selected that shows a running total of contributing area to aide pipe sizing

  7. Results format

    Why does InfoDrainage deafult to showing you the Stormwater Controls summary, and only the Stormwater Controls summary, when a model finishes running?

    This occurs even if the Stormwater Controls are fine but the Junctions are showing flooding.

    I mean, I know you can manually check all the other results summaries, but why doesn't InfoDrainage either open them all or choose the most critical one?

    Thank you for the suggestion and thanks to those who commented and voted. This is to confirm that we've received and reviewed your suggestion and here is our response:


    We believe that stormwater controls are the most critical element of the drainage design. Hence we show the results of SWCs as soon as the simulation is finalised. 


    Users can/should check the rest of the model to ensure that there aren't any bottlenecks in the system. 


    It might be feasible to implement a dropdown menu within the SWC results so we can still show results from SWCs, but we make it easier for users to jump to different screens and check the inflows, connections and junctions.


    Would the above address what is required for this case?


  8. Realistic ground profile for swales

    This is a flaw that's been going since MicroDrainage, but when you change the type of a connection from a pipe to an open channel, like a swale, there's no information at all provided about the actual size of that feature.

    I had one come in the other day, only attenuation on the whole site was in a swale. Parameters for the swale has been set 0.5m base width, 1:3 side slopes, Mannings n 0.03, everything normal and okay with this, right?

    But the manholes at the top and bottom of the link that had been turned into the swale…

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


    If you try to build your swales using the SWCs rather than converting links to swales, you will see that you can start from the top area and go down (1:3) or you can start from the bottom and go up (1:3).


    Does the above address your suggestion? I'd be interested to hear your thoughts once you try it.

    Thank you for the suggestion, and thanks to those who commented and voted. This is to confirm that we've received your suggestion and that it will be reviewed for future consideration.

    We are working on enhancing the long section, so it shows more data in the tables, and we made it flexible so users can select what to view. We are also working on annotating the Hydraulic Grade Line and the Energy Grade Line. This is now on our road map for future releases of InfoDrainage.

  10. InfoDrainage 2023.3 Quick Storage Estimate Print Outs

    Please can a function to print out the quick storage estimates and results summary be made available. Whilst they should only be used for concept designs, it would be useful to have this information for record to show the design process

  11. Mixed decimal place

    I'm using InforDrainage 2023.1 and there are mixed numbers after decimal point. In profile view, there are five digit after decimal point which is unnecessary.

  12. 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…

    This is to confirm that we've received your suggestion and we're in the process of implementing this in InfoDrainage so users can see the slope on the table below the long section. This will be made available to user in future releases of the software.


  15. Please can the output drawings be able to be produced in landscape.

    When using the extend view to produce drawings it appears to be only able to undertake in portrait. Also the title block cannot be changed in size which can make the drawings untidy. Finally can there be an option to move the lables around so they do not clash.

  16. Improved tutorial for setting up a network

    InfoDrainage - i am just trailing software and using the metric tutorial. i do not like loading in items from MicroDrainage or AutoCAD and was hoping the tutorial would show how to quickly setup a highway drainage system with pipes/manholes/gullies.

    when asked "was this page helpful" i put thumbs down, hoping to get a chance to say the above but i cannot type in the feedback form. please update chapter 2 "creating the network" so that new users can setup a simple network - all ive done is click buttons to load random data and do not feel like i…

  17. InfoDrainage - Split subcatchments option for Laurenson runoff routing method

    It is industry best practice to split up the subcatchments in a model into their pervious and impervious areas when adopting the Laurenson (or RAFTS) runoff routing method ie U = 2 and U = 0. The current workflow to achieve this is to setup the model with 2 subcatchments representing the impervious and pervious surfaces within a subcatchment. Existing Innovyze software (ICM and XPSWMM/XPSTORM) provide the user the ability to split the area of a catchment up into a number of different runoff surfaces. A feature like this would be great to have for InfoDrainage.

  20. InfoDrainage - Re-Ordering Tables

    Please can you add an ability to manually adjust the order of Junctions and Connections as the tables quickly become difficult to follow. The automatic re-ordering seems to reset as soon as you make any changes!
