Sewer system operation into the 21st century, study of selected responses from a UK perspective

Abstract

The present study examined the future of UK sewer systems at timescales, up to 2020 and to 2080. The most significant drivers for change were identified for different socio-economic and climate scenarios. A wide range of potential responses to these drivers were studied using the analysis of literature, expert workshops and limited modelling. The assessment of effectiveness of a number of these responses are presented and discussed. In the short to medium term it was shown that technological responses were most likely to be effective. In the longer-term controls on urbanisation and land use were seen to be more effective.
