Upgrading our servers

Friday, March 08, 2019

We are in the process of upgrading the servers on which our Greenfield runoff rate estimation and Surface water storage volume estimation tools are hosted. We therefore have to take the tools down temporarily, the time to carry out the necessary work.

In the meantime, we offer you an alternative version of the tools.  The website has been updated so that when you next log in to access one of the tools, you are directed to these alternative versions. Your browser may open the tool in another tab or window depending on the web browser you use and your preferences.

Same calculation engine, same results

The alternative tools use the same calculation engines, so rest assured that the results will be the same than if you were using the other version of the tools. 

However, there are some differences, which are listed below.  

Different layout and reporting

  1. The layout of these alternative versions is slightly different.
    The top menu has been simplified, giving you options to go back to the main UK SuDS website.
    You will need to go back to the main UK SuDS website to get support information, such as FAQs.
  2. You will not be able to save runs in your secure area.
    Reports will be generated when you click on the "Generate pdf" button.  The report will be available from the download folder or directly in your web browser (depending on the web browser you use and its preferences).

The alternative versions only work on Chrome and Firefox.

We hope to have the servers upgraded by Friday 15th of March 2019.

For any queries about the alternative tools and/or the UK SuDS website, please do not hesitate to contact us at
