Graph sum of multiple objects instead of each selected object
While looking at multiple drainage areas in a basin (in my example), results can become hard to read; it would be nice if you could graph multiple objects and have the option to see the summation of the selection instead of each individual item.

As a user i want to see 'failed' simulations within the Results Management Window rather than 'completed' status
When a sim completes as status Incomplete the sim icon changes to red and the Job control window states sim status Incomplete. However, in the Results Management window the sim status is ‘Complete’!
For consistency and user friendliness; Please can you fix to reflect the status Incomplete? This change will make re-running sims so much easier and save end users not having to delve into IDs to work out which sim need investigation.

ICM - HEC-22 Combination Inlet for continuous grade inlets
Currently ICM has 6 FWHA Gully Inlet types:
ContCo Continuous Curb Opening
ContG Continuous Grate
SagC Sag Combination
SagCO Sag Curb Opening
SagG Sag Grate and
UPC GrateA commonly used Inlet type (particularly in QLD Australia) that is missing from this list is the combination (curb opening + grate) on a continuous grade.
Section 4.4.4.4. in the HEC-22 manual discuss the capacity of these inlets where the curb opening precedes the grate in the direction of flow. It would be particularly useful to include this option in ICM rather than assuming a grate only inlet type or having to…

Pump Station Modelling
Infoworks ICM pump station modelling principle is very basic, adding a pump between two nodes is highly hypothetical. There is no way to add pump station head losses.
I would like to suggest incorporating pump station modelling (for Rotodynamic pumps) with pump curve and system curve theory. Then the model results would be much more realistic.
There must be a tool to incorporate all the accessories in pump stations, between two nodes. Like pump station type, drywall wet well. And Parameters to calculate Pump suction and discharge losses, like all fittings, non-return valves, discharge valves, flow meters etc. This would…6 votes -
odour
Air Phase Model Function - Can Innovyze consider to include air phase modelling function in InfoWorks? At moment, the odour modelling is done separately by various methods using the sewer hydraulic data as the input. As a result, the odour modelling has to be done by different teams and often costing. There is a strong market demand to integrate the liquid and air phase modelling, for example DHI already has a function. It is technically challenging to have a full integration, however there are well developed simplified ways to achieve that.

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. Thanks17 votes -
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…

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)

Merge pond and storage nodes and increase their functionality
Pond nodes:
- allow variable infiltration at different levels (up to 3 different rates)
- allow variable perimeter with level i.e. plan area through which side infiltration can occurs can vary
- no porosity functionStorage nodes:
- 1 porosity value (which only works below ground, above ground it is assumed to be 100%)
- fixed perimeter for infiltration i.e. assumes cylindrical shape for infiltration (despite the plan area changing with level)
- fixed infiltration rate (no change with height)It is not possible to model both porosity and a change in infiltration with height.
I propose that pond and…

Allow the user to choose the flood type of pond or storage nodes
Allow the user to choose the flood type of pond or storage nodes from a drop down as is the case for manholes. As opposed to the current state where the flood type depends on the relationship between the highest level entry in the storage array and the ground level of the node.
From help file: "Storage nodes or ponds can flood. If the highest level entry is below ground level, the pond is considered to have a roof at that level and is therefore sealed. If the highest level entry is equal to the ground level then any water…

Correct calculation of volume within storage node when using porosity
Currently when a porosity value is applied to a storage node, the porosity is only applied for storage array entries which are below ground level. Storage array entries above ground level are assumed to have a porosity of 100%. Between the highest storage array level value below ground and the lowest storage array level value above ground the porosity is assumed to increase linearly between the value you applied and 100%. i.e. the storage is assumed to be conical.
This should be corrected. The porosity value applied should be applied to the whole storage array both above and below ground.…5 votesCould you provide a practical example of porosity above ground?

Revision to manhole representation
ICM's default representation of manholes could be more accurate. The limitations of current setup allows accurate representation of either the shaft or the benching but not both. Thus most people tend to apply chamber areas to invert which overestimates the volume prior to surcharge or the shaft to top of benching which overestimates the volume at the surface.
Because we can now define the benching in the database, it would be better if the default dimensions for manholes were altered to represent 4 critical levels, invert, top of benching, roof, and cover. With associated areas as channel, chamber and shaft.

Multiple Conduit Selection
The Select downstream (or upstream) links button is of limited use. Typically, I would like to select all downstream CONDUITS, in order to create a long section, but I find ICM arbitrarily include overland links (curb & gutter) between nodes and not show the conduit. I guess an SQL could be written, but a simple select conduits only button would be better.

Additional storage calculations
Can we please revisit the assumptions in the additional storage routines.
In a world where everyone has access to accurate property location data, via customer seed points and subcatchments can be any shape or size. The distances between properties and sewers can be much more accurately determined in the calculation than is currently the case, based on the existing A/4L.
The calculation also makes no allowance for private inspection chambers, which in many instances would provide more volume than the pipe.
Two versions of the equation driven by a new field in the subcatchment would also be better allowing lateral…

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.

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.

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.

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.

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.
