StopUP SuDS Tool

The StopUP SuDS tool is a web-based tool designed for non-technical users.

The tool allows users to create a detailed representation of a SuDS network, to apply rainfall, and then to calculate and report on its hydraulic and water quality performance (including Interception!).

In doing that, the StopUp SuDS Tool can assist users in the design and evaluation of planned SuDS schemes.

The tool has been built under the EC StopUP research project. The StopUP project runs until August 2025 and in addition to this the StopUP SuDS Tool will be further developed between February 2025 and December 2026 as part of SuDS-iQ, a project led by Southern Water, delivered by HR Wallingford and funded by the Ofwat Innovation Fund. https://waterinnovation.challenges.org/winners/suds-iq/.

If you have any feedback or undertake any testing of the tool against other drainage models or observed data we would be grateful if you can share those with us at email address support.stopup@hrwallingford.com.

A User Guide for the tool can be found on the StopUP website https://stopup.eu/the-stopup-suds-tool/.
