Résumé / Abstract
In France, the law on national commitment to the environment of July 10, 2010 encourages water services to reduce losses in distribution networks in order to preserve water resources. To support the implementation of this policy, the National Water and Aquatic Environments Office (ONEMA) asked Cemagref to develop a methodology and technical and financial indicators to define and evaluate the actions against water losses (Renaud et al. 2011). Indicators of water losses commonly used in France do not take into account the pressure even though this factor is now recognised as an important parameter to consider for reducing water loss (Renaud, 2010). Very often, those responsible for water utilities consider that the average pressure of a network is a parameter poorly defined and difficult to obtain. To overcome this obstacle, Cemagref decided to study the practicality of defining and measuring pressure indicators, representative of a service zone, in the French context (Sissoko, 2010). This article presents the main results obtained in this study.
