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)

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.

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

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.

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.
6 votesGreat ideas! The goal is the simplify the physical location to either measured (as-built) or designed locations of pond outfalls, while either logically enforcing the relationship of outfalls to pond/outlet without forced links that do not represent physical pipes.

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…

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.

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.

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.

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.

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.

Pipe collision check
Client feedback: an automatic check for colliding pipes would be highly appreciated to avoid nightmares in the construction.

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,

Infoworks ICM - XPSWMM
Provide a easy model/network transport option from one program to the other. Many municipalities within WA utilise XPSWMM and therefore are note able to read an ICM model.

Infoworks - Pipe grade calculator
Pipe grade calculator between US and DS inverts, Ultimately having the ability to calculate downstream or upstream inverts over a long network based on a specified grade from either a DS or US invert level as a starting point.

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.

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)

Simple means to set initial storage area water surface elevations
Please incorporate a system for setting initial water surface elevations in storage nodes that works as easily as the process is in XPSWMM or HEC-RAS. The program should hold this water level during warm-up stabilization.

Modelling of mud and other non-Newtonian flows
We've a lot of work at the moment modelling the failure of tailings dams. Tailings dams typically have material that acts in a non-Newtonian manner. To effectively model these sorts of fluids would require the inclusion of additional fluid properties. The Bingham method (https://en.wikipedia.org/wiki/Bingham_plastic) has been successfully applied in other applications.

Orifice to limit flow in both directions
A limiting discharge set on an orifice should limit flow in both directions. Currently, the orifice limits flow in the forward direction; however, flow can go in the reverse direction at an unlimited rate. Hydraulically, if there is a physical feature that limits flow, it seems that it would limit to (for example) <10 l/s and > - 10 l/s.
