    AQUARENOVA project - Active management of the Bas Gapeau aquifer to prevent saline water intrusion
    The city of Hyères-les-Palmiers (France, Var) and Suez Water France (operating the drinking water service since 2012), now develops AQUARENOVA, a program of abstraction control and restoration of natural resource, leading to a sober economic development. This project is declined in two main axes.**The first one aims to reconquer network performance in a context of sharp increases in the summer consumption (x4).**The second axis is the restoration of the main water resource of the city, the Bas Gapeau aquifer. It is first of all a real-time abstraction control, based on a continuous monitoring of water level and conductivity on some piezometers. The gradients method shall optimize abstraction without risking saline intrusion (detected early 2000).**The results measured since 2012 are very significant. Suez Water France also conducts aquifer recharge works by winter abstraction into the coastal river Roubaud, in order to form a piezometric dome to be used in summer.**This replenishment is operational from November 2015 to ensure the city water autonomy and to protect the groundwater resource against saline intrusion even under severe drought.**
