The extent to which the case studies have embraced the SuDS principles and exemplary good practice will vary and will often reflect the availability of guidance, the brief from the client and the subsequent philosophy and design criteria.

However, all examples demonstrate the advantages of SuDS and provide improvements in either water quality, water quantity and amenity/biodiversity compared to traditional drainage. In some cases all of the broad objectives are realised as well as delivering other multiple benefits.

Many of the case studies below have been peer reviewed, we also have award submissions (ie case studies) that have not been peer reviewed that can also be found here. We now feature “Light” case studies that have not been peer reviewed, these are marked as such on the case studies and the thumbnail image.
