A technique is described for the rapid assessment of which parts of an existing sewer or pluvial drain network may be below the watertable and, therefore, in areas of potential gain from groundwater. The technique, which arose from data conditioning for the pipeline leakage part of an urban water balance model array, can be used together with a groundwater flow model to undertake scenario modelling. The extent of effects on the sewer network from different groundwater level rebound scenarios can then be rapidly predicted. Such changes in water level can arise for example from decline in nearby urban/periurban groundwater abstraction or as a consequence of increased urban recharge. An example is given for a 6.3 km2 suburb of Doncaster, England with a 128 km sewer and pluvial drain network.
