Description

Priority (ex GRENELLE) and sensitive catchment supply areas (AACs) for the AEP Data sources: DDT28 / SGREB A column has also been added to link to AAFCs in ZAR (Reinforced Action Areas). 12/11/2024 : in comments, distinction between Priority - Gender 2009 and Priority - Environmental Conference 2013 Then addition in March 2025, of the corresponding AAC UAAs (on the 28 and the bordering departments), and in July 2025 of a column for the Prefectural Decrees under the Action Programmes (APs). Attention: only the 2 AACs of Vernouillet and Vert-en-Drouais have been defined on the agricultural parcels (RPG 2022). The other perimeters correspond to the zonings defined by hydrogeologists. In response to the requirements of the Water Framework Directive, the Law on Water and Aquatic Environments of 30/12/06 strengthened the mechanisms for controlling diffuse pollution of agricultural origin by creating protection zones for catchment feeding areas. The ½ implementation of this new resource protection system leads to the delineation of catchment supply areas (AACs, sometimes also called catchment supply basins or BACs) that include AAC protection areas.For surface water catchments, the AAC corresponds to the sub-watershed located upstream of the water intake. For groundwater, a common methodology for the delineation of AAFCs at the national level has been proposed. To the right of the methodological guide produced, the feeding basin of an underground catchment is defined as the place of the points of the soil surface that contribute to the feeding of the catchment. Some catchment feeding areas are identified as priorities in the Water Management and Management Master Plans (WMPs) and Programmes of Measures. A AAFC is thus defined, after a technical study, as the area from which the water supplying a catchment or several close catchments originates. Therefore, it is proposed to include the relevant AAC identifier among the attributes of the data standard locating drinking water sampling points (#0000002 N_PRELEV_AEP_P).
