Groundwater

National Code of Sub-Soil (BSS) assigned by the Office of Geological and Mining Research (BRGM) to underground structures including water abstractions. Established according to the principle of positioning a point on a 1:50,000 geological map, the BSS code is of the following form: 08035X0398 / F. The characteristics that are associated with it (geographic coordinates, depth and geological profile) are then used to precisely locate each intake and identify the abstracted groundwater.

All facilities, services and activities which allow, by using untreated water, producing water which meets the drinking water standards in force, then distributed to consumers. We consider five distinct steps in this supply, abstraction, intakes, drinking water treatment, conveyance (transport and storage), and distribution to the consumer.

In the strict sense, a device used for measuring the pressure head at a given point in an aquifer system, which indicates the pressure at that point, by allowing the observation or recording of an unconfined water level or a pressure. The piezometer concept was extended to all man-made (wells, wells, gravel pits, etc) or natural structures (sinkholes, caves, etc) that allow access to groundwater. We then rather speak of non-operated well which allows measurement of the groundwater level at a given point of the water table. This level which varies with the groundwater exploitation provides information about the…
