Including public perception data in the evaluation of the consequences of sewerage derived urban flooding

摘要

This text reports research which was undertaken to assess the failure consequences associatednwith sewerage systems. In an effort to move away from considering only flood volume, depth ornextent, the text will focus on how a survey of public opinion was used to inform the developmentnof a consequence scoring methodology. The failure consequences considered range from internalnflooding of properties, to road closure, environmental damage and odour problems. The textnreports the extent to which experience of flooding influences perceptions of failure consequencenand sewerage system management. It is also outlined how this data was used, along with otherndata sources, to construct an objective scoring process that can be used to evaluate failurenconsequence and readily prioritise sewerage maintenance.
