The technical and economic optimization of the management of water networks of all kinds implies the implementation of new solutions relying heavily on the digital revolution in terms of communicating objects and spatialized management.

In the context of the management of the water networks of Montpellier City, the objective of Veolia is to develop innovative communicating sensors, adapted network monitoring, predictive quality models and a new platform for the management/exchange of measured data. This “hypervision” responds to the new business needs of operators and design offices, as well as to the demands of local authorities which, in application of European regulations, will have to manage increasingly large and complex territories in the future.

In this context, the PCSWMM software has been used for the implementation of this global strategy, based in particular on specific innovative modules allowing: (i) to trace the water sources at any point of the drinking water network, (ii) to test the sensitivity of the valves in the drinking water networks, (iii) to estimate the quantities of H2S expected in the sewerage networks, (iv) to collect and treat the data from the sensors installed in the field.

The results obtained thus enable more efficient management of all water networks for the Montpellier City, by anticipating future phenomena as well as possible.
