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).

为响应《水框架指令》（Water Framework Directive）的相关要求，《2006年12月30日水与水生环境法》通过设立集水补给区保护带，强化了对农业面源污染的管控力度。该新型资源保护体系的实施，需划定涵盖集水补给区（catchment foraging areas，AAFCs，部分场景亦称为集水补给盆地或LACs）保护范围的集水补给区域。针对地表水取水作业，AAFC为取水口上游的子流域；针对地下水，目前已提出通用的全国AAFC划定方法。在所编制的方法指南中，地下集水补给区的补给流域被定义为：地表所有可为该集水区域提供补给的点位所在范围。部分集水补给区已被纳入《水资源管理总体规划》(SDAGE)及各项措施方案的优先保护名录。经技术研究论证后，AAFC被明确界定为：为单个或多个集水区域提供水源的区域范围。有鉴于此，建议将AAFC标识符纳入饮用水采样点位（0000002 N_PRELEV_AEP_P）所对应的数据标准属性中。
