  1. Import/export of asset data to/from CSV

    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.

  2. "Copy to clipboard" alongside print/export on Microdrainage spreadhseet input/outputs

    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)

  3. Assess scenarios based on annual water balance (runoff, infiltration, evaporation)

    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

  5. Change the size / dimensions of multiple manholes at once

    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!

  7. Easier selection of FEH and FSR Rainfall in the "Seasonal Return Period Wizard"

    Sometimes we are required by the LLFA to run storms <60mins with FSR rainfall and storms >60mins with FEH rainfall. This requires the "Seasonal Return Period Wizard" to be run twice following changes to the network and then exported in separate files.

    It would be much quicker if this could be specified in the wizard.

  8. Allow SOIL values < 0.15

    The Rural Runoff estimate tool in MDSUDS does not allow values of SOIL below 0.15.
    The UKSUDS greenfield runoff tool defaults to a value of SOIL=0.1 where SoilType=1
    This produces a significant difference in results. This difference results from using values of SOIL from FSR vs Wallingford Procedure and FSSR7
    It would be better if the MDSUDS tool allowed values of SOIL down to 0.1 for compatibility, and if the default values were standardised across the industry.

  9. Add update to existing network for the 'Export to Civil3D’ in DrawNetCAD

    It would be very useful if DrawNetCAD had the option of updating an existing Civil3D pipe network when using the Export to Civil3D option.
    The Autodesk Microdrainage Utility has this ability, albeit it can be unreliable.

  10. Missing design function and short cut


    1. Add vehicle tracking function to software.


    2. Be able to save to dwg format individual roads ( plan, long section and cross section)
      all layers with one click rather than saving the whole development plan if only revising one road.

  11. Site 3d default manholes

    Can the default manholes be the most recent design and notation please? It currently defaults to SfA 6, need to be SfA7 currently or even have a user editable toggle to decide what version is being used. At the moment I have to edit every manhole separately from 6 to 7.

  12. Link from CIRIA BEST Tools

    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.

  14. Link to InfoAsset Asset Management Software

    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.
