The future of the network of non-drinkable water -Eau Non Potable (ENP)- is a complex issue that the City of Paris has been concerned about addressing for over twenty years. Up until the Consensus Conference held in December 2009, studies had for the most part been condemned and systematically put aside. The Consensus Conference permitted new ways of considering the question to emerge which needed to be examined in greater detail. It was at this stage that the City of Paris and Paris Water - Eau de Paris-, wanting to continue consultations on these emerging ideas, asked the Paris Urbanism Agency (Apur) to carry out an in depth study in preparation for a Council of Paris board meeting on the subject in 2012.

Made up of two major parts (analysis / diagnosis and ways of considering the potential of the ENP network), this study takes stock of the situation and proposes directions for the future of waterways and uses for their non-drinkable water. These possible directions take into account the future development of Paris and its metropolis and more globally, aim to return waterways fully to their,  too often neglected,  place among the urban services.

Findings of the study tend towards the maintenance, even an extension of the ENP network in response to the sustainable development criteria for an evolving metropolis.
