Catchment Food Areas - France Entire

The Capture Food Area (AAC) is defined on a hydrological or hydrogeological basis. It corresponds to the surfaces on which the water that seeps or flows participates in the supply of the water resource from which the abstraction is made. Thus, the AAC corresponds to: - for a sampling point (STP) intended for drinking water in surface water: to the sub-watershed upstream of the water intake(s), if any, supplemented by the surface concerned by the supply of groundwater external to that watershed (e.g. pedestal tablecloth or accompanying tablecloth of watercourses), - for a TPP intended for drinking water in groundwater: the catchment area of the water point(s) (location of the points on the soil surface that contribute to the catchment supply). The AAFC may involve several sampling points, but it is linked to a single Basin Administrative District. The basin division will be that of the referring TPP municipality, associated with the AAC. NB: The concepts of ‘feeding area’ and ‘feeding basin’ for catchments (AAC, BAC) are here considered synonymous.
