Process for making use of groundwater collected by drilling, employing at least two successive levels of pumping (2, 7) of the water before sending it to a treatment factory, specifically a primary pumping (2) in which water is pumped out of a sector where the groundwater is rapidly recharged and where it benefits from a natural filtration through the earth, the water produced by this first pumping being directed into an artificial open-air re-feeder basin (5) from where, as it filters down to the aquifer, it undergoes filtration for a second time in an oxidizing aerated medium, and a secondary pumping (7) performed in the vicinity of the re-feeder basin to supply the treatment factory. |
