Environmental technology of artificial recharge of groundwater by sewage

Globally, the pressures on water resources are likely to intensify. In this context, the recycled wastewater appear as a resource essential alternative and artificial recharge of ground water in these waters will play a central role. However, several obstacles, technical, regulatory and psychological, remain to be overcome if this technique becomes widespread.
The objective of this project is to define the economic, environmental and health requirements and the technical implementation (design and engineering) systems and innovative purifying controlled. These systems are based on the implementation of reactive barriers for ground suitable for artificial recharge of coastal aquifers impacted by the invasion of saline water from treated wastewater. This infiltration basins treated wastewater whose purification ability is completely reactive control. The layer of soil infiltrating innovative, called reactive barrier is designed with combinations of materials and engineering specific, depending on the geological and hydrogeological local configuration, quality of water to purify and environmental constraints and social
Therefore this project proposes to juggle expertise, research and environmental health and social acceptability.
