Abstract
A GIS-based BMP tool has been developed within the EU-funded SWITCH project to enable stakeholders to identify appropriate BMPs and their locations to facilitate the control of urban runoff and to reduce the pollutant loads discharged to receiving waters. The attenuation impact of the installed BMPs on separate sewer flows has been predicted by linking this tool to a hydraulic model
(STORM). The capability of this combined tool is illustrated using a 4.5 ha section of a city centre
development site subjected to measured rainfall data for an extreme storm event. Green roofs and porous paving are used as illustrative examples of BMPs and are shown to have the potential to remove 23-26% and 22-28%, respectively of hourly based flows depending in the incident rainfall volumes. When used in combination, these BMPs have the potential to alleviate exceedance flows in
the receiving pipe system. The installation of BMPs is also demonstrated to reduce the short term flow
variability caused by rainfall fluctuations and hence to enable planners to more accurately design sewer systems with the required capacity.
