The sizing calculator in the pond build pop-up enables one side lpe only.
There are now LLFAs that require level benck of at aleast 1.5 m width after 0.6 m depth in a basin.
It is currently not possible to use your calculator to establish such basin properties.
This would be useful.

Just like in CAD DrawNet you can use the CAD tools to snap the points of the catchment areas to specific points, it would be useful to have a snapping tool built into the MicroDrainage program. It could be a simple tool so you can either put a new point of the area anywhere, or when you're close to a point of another area you can snap to that point. This would save going back and forth between MD and CAD.

It would be good to have an option in underground stormwater controls to have a separate option for exceedance level and Ground Level
By taking the exceedance level as GL, it makes the Long sections look distorted when in reality it is common for our designs to have circa. 1m+ cover from top of tanks/soakaways etc to ground level.

For MH tables and report outputs, it would be good to have an option to report chronologically, e.g. 1-30.
I understand it numbers them on the first Manhole built in the model however I think it would make more sense to go from shallowest to deepest, e.g. U/S to D/S. As is quite common in design additional MHs need to be incorporated further into the model due to clashes or change in direction etc, so it would be best if all outputs and MH tables followed the numerical order.

It would be great to have the option of providing an additional level of customisable detail which could be configured on MH Schedules.

As an example including practical details around the cover – contractors want to know and see more from a MH schedule when out on site.

Examples of details around the type of cover:
Cover Size
Opening Size
Recessed
Solid Top
Loading Class

Currently this level of additional detail is often added manually to MH schedules exported from software.

when I start a new network, the criteria automatically selects my default manhole and pipe size file, can you change it so when importing a file for the first time it selects my standard default files, older versions did select the default file

to be able to change the default button in storm duration so I can set up my own default settings

It would be very useful if there was a way for the true ground profile to also be exported on long sections. Currently, when exporting long sections from microdrainage, the true ground levels are only shown at manhole locations and a straight line is used to replicate ground level between the manholes. Could a 3D terrrain file possibly be loaded into microdrainage so that the true ground profile is shown when exporting long sections?

Urban creep is an additional test which is not applicable to all runs. So would be more useful to not have a universal application of creep (to all storms). Would be better to have the facility to apply to selected storms only.

Would be useful to be able to 'replace outline' of a stormwater control by importing a polygon (e.g. DXF, SHP etc), rather than the existing options which are just to redraw in ID only.
Every project there seems to be need to replace an outline from another drawing (as architechtural desisns evolve). At teh moment have to re-set up the control each time this occurs.

CIRIA make a tool for valuing the benefits of green infrastructure. The results enable users to understand and quantify the wider value of SuDS and natural flood management measures. Being able to include this in the drainage design when comparing scenarios would be useful.

Te has specific meaning in the UK when using the rational method (modified).
Tc also has speific meaning (Te + sumTf).
It would be better if the software wants the user to input a Te, that it calls it Te. At the moment it calls the Te Time of concentration, which is very confusing.

DSD import/export for MicroDrainage exists but HydroWorks is now dead. A more generic import/export would be beneficial for exchange of information with other drainage simulation packages and with GIS systems for existing networks; something similar to the import/xport functins in ICM would be ideal.

Would greatly simplify the process of getting results/details from MD into a report, skipping a stage in the current process (Export to CSV/Excel - Open)

Assessment of the annual water balance is an important criteria to evaluate drainage design at neighbourhood level.
Functionality to assess scenarios in a chart (similar to typical pre-urban vs. urban) would save time in GIS-postprocessing

MicroDrainage Network

It would be very useful if it was possible to change the dims of many manholes at once. It'a a very laborious and time consuming task to change each dimension one-by-one, especially if the network is very large!

Support a wider range of linear drainage channels.

Add a link to take drainage design data into Innovyze's InfoAsset Asset Management Software to complete the cycle of design - build - manage - maintain cycle.

Add the ability to have a maintenance sheet in the print outs for SuDS structures.
