Dataset Direct Download Service (WFS): Strategic tablecloths for the future AEP of the Seine-Normandie basin

Strategic tablecloths for the future EPA correspond to the water resources that will allow the supply of drinking water in the future, taking into account the potential of the resources and changes in the need for drinking water. For these resources, meeting the needs for drinking water is recognised as a priority. These are resources: — which meet quantitatively the challenges of future supply; — located close to current and future consumption areas; — of the most satisfactory quality compared to other resources in the sector of the same quantitative scale. — currently operated, with the exception of the chalk table under alluvions in the Seine Valley. The strategic tablecloths and associated safeguard zones for the future are intended to be integrated into the basin’s protected areas register. The identification of strategic resources may lead, depending on the qualitative or quantitative vulnerability, to the definition of complementary management measures in the current SDAGE. 19 sectors of groundwater are involved, associated with 16 groundwater bodies and 14 bodies of groundwater. SDAGE 2022-2027 identifies these areas in its orientation 4.7面向未来美国环境保护署（Environmental Protection Agency, EPA）的战略台地，对应着可支撑未来饮用水供应的水资源，其遴选依据为水资源禀赋潜力与饮用水需求的变化趋势。对于此类水资源，保障饮用水需求已被确立为优先事项。 此类资源需满足以下条件： — 在水量维度可应对未来供水挑战； — 临近当前及未来的饮用水消费区域； — 在同等规模量级的同类水资源中，水质表现最优； — 当前已投入运营，但塞纳河谷冲积层下的白垩台地除外。 上述未来战略台地及其配套的保护缓冲区，将被纳入流域保护区名录。 根据水资源的水质与水量脆弱性特征，识别战略水源后，可在现行流域水环境管理总体规划（Schéma Directeur d’Aménagement et de Gestion des Eaux, SDAGE）中制定相应的补充管理措施。 本次共涉及19个地下水管控分区，关联16处地下水水体及14个地下水赋存单元。 2022-2027版流域水环境管理总体规划在其第4.7号指引条款中明确了上述区域的相关要求。
