Abstract
Sustainable drainage systems (SuDS) design and retrofitting is predominantly based on expert opinion supported by descriptive guidance documents. The aim of this paper is to develop an innovative rapid decision support tool based on novel ecosystem service variables for retrofitting of key SuDS techniques. This unique tool proposes the retrofitting of a SuDS technique that obtained the highest ecosystem service score for a specific urban site. This approach contrasts with methods based on traditional civil engineering judgement linked to standard variables based on community and environment studies. For a case study area (Greater Manchester), a comparison with the traditional approach of determining community and environment variables indicates that permeable pavements, filter strips, swales, ponds, constructed wetlands and below-ground storage tanks are generally less preferred than infiltration trenches, soakaways and infiltration basins. However, permeable pavements and belowground storage tanks also received relatively high scores, because of their great potential impact in terms of water quality improvement and flood control, respectively. The application of the proposed methodology will lead to changes of the sustainable drainage infrastructure in the urban landscape.
