The dataset represents the wastewater discharge points of the public sewage network. The data presented are a part of those managed in the SIRI Water Resources Information System of the Piedmont Region - Integrated Water Service Component. The insertion and updating of the data is the responsibility of the Optimal Territorial Area Authorities (ATO), each for the part of the territory under its jurisdiction. The updating frequency is variable. A WFS service (vers 2.0) of the Complex Feature type is made available. To use this type of service it is recommended to use - for example - the QGIS 'WFS 2.0 Client' plugin. A WMS service is also made available with the data exposed by the WFS Complex Feature: https://gisserver.territorio.csi.it /geoserver/decsiraogc_scarichi/wms?service=WMS&version=1.3&request=getCapabilities The service is currently published with access restricted to public administration users since the data is subject to verification.
