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.

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 StopUP research project and it is undergoing further development until the end of the StopUP project in September 2025. The tool is a simple high-level SuDS evaluation tool and therefore is not a full hydrodynamic model. 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 and Technical Guidance document for the tool can be found on the StopUP website https://stopup.eu/the-stopup-suds-tool/.
