Abstract

The great majority of the Gironde department (South west of France) is supplied with drinking water from deep groundwater with very high inertia. Some of these aquifers are overexploited as a result of withdrawals intended for more than 90% to supply drinking water. The management of these resources therefore requires a good knowledge of the water needs of the Water Supply Systems (WSS), including the losses of the distribution networks. In this context, the SMEGREG (public basin establishment which aims to help preserve and enhance the deep aquifers of Gironde) and INRAE (public research body) are leading a research collaboration to progress in the prospective estimation of water losses from WSS of Gironde under the influence of changes in urban density and demography. This study aims, on the one hand, to build a benchmark for evaluating the performance of services in terms of water losses as a function of urban density, and on the other hand to study the respective changes in the population, the length of the networks and the number of connections.
