The drilling and groundwater collection techniques classically used in porous and fissured media are not very varied. implemented in porous and fissured environments are not very varied. The choice of the technology to be adapted depends not only on the hydrogeology (geometry of the geometry of the aquifer, hydrodynamic parameters, potentialities) but also external external constraints, such as topography, hydrography, risk of salinization and salinization and pollution transfer from the surface, land use, execution conditions and execution conditions and equipments
