A SuDS retrofit project for a site which comprises of two schools. The installation of retrofit SuDS achieved a number of objectives:
Intercepting overland flow from adjacent land in collector swales
Storage of unpredictable water volumes in landscaped features
Cost effective replacement of conventional drainage infrastructure that was undersized for severe storms which often caused flash flooding
Reduction of silt blocking using silt interceptors
Re-routing of drainage to natural watercourses
The SuDS scheme provided features such as a cascade and wetland, which provided an amenity benefit to the community.
