For specifiers, there are both legal, corporate, and economic reasons for finding better and more sustainable ways to manage surface water drainage on new developments. Therefore, the return on the developer’s investment in the land and, given that well-designed SuDS offer additional benefits of amenity and biodiversity, properties protected by SuDS can attract a higher premium. Indeed, some housebuilders have advertised the use of SuDS as a selling point.
