  1. Our clients would like to see InfoWorks ICM apply daylight savings time corrections to wastewater and tradewaste inflows

    As a toggle setting in the run settings or in a wastewater/tradewaste pattern, this would shift the diurnal patterns based on the simulation date and daylight savings time start/end dates instead of working on standard time all year long. Mathematically, this is really straightforward, but may require internal indexes (and warning messages?) for the DST start/end dates. It would also require something to turn this feature on and off as there are several areas that do not observe DST. This feature would help us more accurately predict combined sewer overflow volumes and durations where base wastewater flow has a significant…

  2. Improve ground infiltration simulation parameters.

    Could we have a 'Node level affects groundwater infiltration' for the soil store please?
    This simulation parameter was introduced to InfoWorks ICM recently to limit infiltration from the ground store to the model. Could this be extended to limit flows from the soil store as well?
    As often when are using models for design purposes, infiltration can become excessive in design events compared to verification. Therefore we have to manually reduce soil store inflow, often requiring new limiting discharge orifices and nodes at each subcatchment with GI applied. Thanks

  3. blockage

    Applying pipe blockage is a standard required in Australia and the functionality in ICM to do this is not user friendly (using blockage links). A simple % pipe blockage in the conduit properties should really be an option. This is particular the case for cross drainage and also orifice and pipes leaving detention basins (where a pit isnt used)

  4. bottom opening

    Beside an upstanding vertical orrifice, it would be practical to be able to implement horizontal 'bottom holes' from one node to an underlaying node. e.g when a ditch can drain to an underlying conduit by means of a bottom opening. This might be a more straight forward implementation then the weir circumference workround method which is now often used. if possible both circular and rectangular.

  5. Calculating volume storage on river reaches

    In the application of ICM, we often count the regulation volume of river channels.But at the moment we can only calculatethe total available volume of channels/river reaches between two cross sections by using length and cross sectional areas.If the number of river sections is very large in the model,it will take a lot of time and effort to accomplish this work. It would be great to have the tool to calculate volume storage on river reaches automatically.

  6. Selection List Subtraction

    I was looking for a way to subtract one selection list from another. In other words, we would like to remove overlaps between selection sets but it seems there is no way to do that easily in ICM.

    It is highly recommended to include this feature for future versions as competitors such as Bentley SewerGEMS have already had this for years now.

  7. Change Variable Speed Pumps Image

    The image for Variable Speed Pumps under the "Other Special Diversion Examples" section is likely wrong. Looks like it is a copy of the image for Pump discharge pipes. Would be great if you could update with the right image! Thanks

  8. Storage area polygons

    Storage nodes often represent detention basins or other locations with large areas. Pipes enter/leave from opposite sides. With the standard link/node configuration, one or more link will be mis-configured compared to the actual location.

    I have long wanted to have a storage area polygon, with links connecting to the nearest edge, rather than the center.

    Thank you for this request. I just wanted to confirm whether this was for display purposes only to allow for better representation of the actual configuration on site or whether the location of pipes was expected to influence the hydraulics in some way.

  9. Enable alternate versions of the SWMM engine within ICM

    I would like to have the option to use a different version of the SWMM engine to be run instead of the latest Innovyze version. In some cases this is required, but it is often very helpful to confirm the results from previous versions.

  10. XPSWMM Inlet capacity - head difference rating or geometry-based inlets

    Inlet capacity creates a second node internally to XPSWMM. Currently, the rating curve methods for it are calculated based on node depth, rather than head differential, which doesn’t work right with 2D if the storm sewer HGL is above the gutter.

    I really like how inlet capacity doesn’t require adding an extra node. I would like to suggest it be expanded as follows:

    1) Simply add a head differential rating curve.

    2) Add a structure-based option for inlets,

    For a structure-based inlet, it could essentially be a multi-link. I would like to have a global database of standard inlet types…

  11. Structure flow mode reported in the results

    Sometimes when evaluating results at structures we see strange results that require investigation; invariably we find out that this is because the flow mode has changed. (e.g. from free to drowned). It would be very helpful if the ICM results were able to report the flow mode as a time-varying output. This would result in a lot of time saving when investigating models. For reference I am referring to the Flow Mode functionality that is available in InfoWorks RS and Flood Modeller Pro.

  13. Circular sluices/penstocks would also be useful

    Similar to the rectangular flap valve request, circular sluices would avoid workarounds trying to estimate the rectangular equivalent to a half closed circular penstock (or worse still a half closed egg shaped penstock)

  15. Wide "Oval" shape ID

    conduit shape ID "Oval" only allows Height > With. So for "horizontally" wide oval conduits a new conduit shape has te be defined. It would be practical if the standard "Oval" also allows a with greater than the hight.

  16. Auto populate an incremental ID for objects such as lines/polygons/subcatchments etc.

    Often source data is provided with a non unique ID.

    Nodes auto generate an ID, and conduits will create a node, but the remaining asset classes struggle somewhat and often you need to manipulate the GIS data.

    I would like to be able to have ICM (and WS Pro for that matter) auto populate a unique ID (such as row ID).

    There used to be a blog post written with a Ruby script to do this, but it appears to have been removed from the website. Alternately post the Ruby scripts again somewhere.
    Thanks,
    Ann

  17. Update user defined vortex controls in ICM so hydrobrake head discharge curves can be modelled

    Current user defined vortex controls don't accept head discharge curves where the discharge reduces for increasing head i.e. what happens in a hydrobrake. It would be useful to get this updated to ensure consistency between ICM and drainage design.

  19. Simulation engine control update

    Since the beginning of ICM and allowing to send simulation to other computers in the network, there was a need for knowing exactly who is currently sending simulations and to which computer. Please update the ICM with this improved functionality for the normal user, not for admin only. These people are the ones who send simulation to the network, not IT people!

    Thank you for the addition of this request, we are in discussions about how this might be achieved as the level of awareness of tasks is varied between agents. Would a dashboard showing who sent which simulation where (which are still ongoing) be sufficient? This would be without the progress those simulations have already made available as a first step.

  20. I would like the option to model pump station that operate using VFDs.

    I would like to be able to enter the full and reduced speed pump curves for each pump station that is controlled by variable frequency drives. In addition, I would need the set point or control that causes the pumps to ramp up to full speed.
