Perimeter of wastewater treatment plants

Large-scale localisation, in the form of a layer of polygons, of treatment plants (steps) and other wastewater treatment plants, with their main information. This layer concerns the entire department of Loir-et-Cher. The polygons delineate the complete right-of-way of the installation. These are obtained by photo-interpretation of the BD ORTHO IGN from the base of the step of the Departmental Water Quality Service of the General Council of Loir-et-Cher, supplemented by ad hoc field missions. The layer is available in Shape format (ESRI) in RGF93 Lambert93.
