SuDS-iQ will deliver a national online collaborative Sustainable Drainage Systems (SuDS) platform that will support a collective understanding of what SuDS are, how SuDS work, and the benefits they provide. The platform will accelerate efficiencies in partnership working and consideration for and implementation of environmentally beneficial drainage solutions. 

“ Through investment in Sustainable Urban Drainage, Southern Water is aiming to drive a future of Cleaner Rivers and Seas in the water industry. The SuDS-IQ tool will work to promote collaboration between the stakeholders required for adoption of nature-based solutions. We’re aiming to build future resilience and regenerate the environment.” – Greg Mullet, Chief Engineer, Southern Water 

Update from the project (April 2025)

A project start up meeting was held in February 2025 and as such HR Wallingford and CIWEM have undertaken some tasks associated with Phase 1 Platform co-creation. These include: developing a living Impact & Engagement Plan; engaging with water company partners to help establish the regional collaboration groups; develop and promote an online survey to obtain input on existing and future SuDS collaboration requirements (which to date has 120 responses); co-creation workshops to explore the survey findings in more detail and obtain feedback on direction of travel have been planned for mid to late May. HR Wallingford has also started producing design documents in preparation for the upcoming co-creation workshops where input from future users of SuDS-iQ will be gathered. These documents include user-stories, mock-ups, workflows and specifications and will help explain the SUDS-iQ concepts and ideas in a visual way.
