Catchment Feed Area (ACA) for AEP — Tarn

In response to the requirements of the Framework Directive on Water, the Law on Water and Aquatic Environments of 30/12/06 strengthened the control systems for diffuse pollution of #x27; agricultural origin through the creation of zones for the protection of areas of ​​#x27; feeding of catchments. The implementation of this new resource protection system leads to the delimitation of catchment areas (AAFC, sometimes also referred to as catchment feed or LAC) that include AAFC protection zones. For surface water abstractions, l'AAC is the sub-basin upstream of the water intake. For groundwater, a common methodology for delimiting AAFCs at the national level has been proposed. In the law of the methodological guide produced, the basin d'feeding d' underground capture is defined as the place of the points of the soil surface that contribute to the feeding of the catchment. Some catchment areas are defined as priority areas in the Master Plans of Water Management and Management (SDAGE) and measurement programs. An AAFC is thus defined, after technical study, as the zone d’#x27; where the waters supplying one catchment or several close catchments originate. C'this is why it is proposed to include the relevant AAC identifier among the attributes of the data standard locating the sampling points of drinking water (#0000002 N_PRELEV_AEP_P). __Origin__ Flood envelope drawn by DDE64, following survey surveys.
