Capture Feeding Area (ACA) for the AEP in the Drôme

In response to the requirements of the Water Framework Directive, the Water and Aquatic Environments Act of 30/12/06 strengthened the control of diffuse pollution of agricultural origin by creating protection zones for catchment feeding areas. The implementation of this new resource protection system leads to the delineation of catchment foraging areas (AAFCs, sometimes also referred to as catchment feeding basins or LACs) that include AAFC protection areas. For surface water abstraction, the AAFC is the sub-watershed located upstream of the water intake. For groundwater, a common national AAFC delineation methodology has been proposed. At the right of the methodological guide produced, the supply basin of an underground catchment is defined as the place of the points on the surface of the soil that contribute to the feeding of the catchment. Some catchment foraging areas are identified as priorities within the Water Management and Management Master Plans (SDAGE) and in the programmes of measures. A AAFC is thus defined, after technical study, as the area from which the water supplying a close catchment or several catchments originates. For this reason, it is proposed to include the AAC identifier in the attributes of the data standard locating drinking water sampling points (0000002 N_PRELEV_AEP_P).
