However, planning of retrofit and new SUDS remains unclear in the context of pollution control, hydraulic efficiency and urban planning. Recent research has produced an initial methodology for the design and planning of retrofit SUDS in combined sewer areas. The methodology was applied in this new study initially to construct a database of all retrofit options such as roofs, car parks according to their land use. A second inventory was created for open spaces, classified according to their functions: vacant and derelict land; parklands; private property; and play areas. A conceptual disconnection of urban surfaces was analysed for two trial locations using a hydraulic model for the drainage area and the studies indicated the need for catchment scale disconnections. It was found that different priorities result where an improvement in water quality in the streams is preferred over options which only address hydraulic deficiencies. A framework for prioritisation of retrofit SUDS based on water quality improvement was developed addressing the type of drainage system, the land use, the type of retrofit option, and the available open space.
