The dataset on coastal Urban Waste Water Treatment Plant (UWWTP) was created in 2019 by AZTI for the European Marine Observation and Data Network (EMODnet). It is based on the "Waterbase-UWWTD" data (Urban Waste Water Treatment Directive – reported data) provided by the European Topic Centre on Inland, Coastal and Marine waters, and available at https://www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-8. Based on data selected from the reporting of Member States as part of the UWWTD implementation, the dataset presents the available information (location, capacity and actual load treated, type of treatment, aggregated data on the performance of plants) on individual UWWTP, and collecting systems without UWWTP, located in NUTS3 regions bordering transitional, coastal and marine waters. It is available for viewing and download on EMODnet - Human Activities web portal (https://emodnet.ec.europa.eu/en/human-activities). The geographic coverage is: Belgium, Bulgaria, Croatia, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Latvia, Lithuania, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, Sweden, United Kingdom. The description of all attribute fields of UWWTP is given in the Waterbase-UWWTD (https://www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-8/waterbase-uwwtd). Compared with the previous version, this new version considered late deliveries and corrections made by several countries during 2021 (Waterbase-UWWTD; version 8 published 19 May 2022).

The geodatabase on coastal discharge points from Urban Waste Water Treatment Plant (UWWTP) was created in 2019 by AZTI for the European Marine Observation and Data Network (EMODnet). It is based on the dataset "Waterbase-UWWTD" (Urban Waste Water Treatment Directive – reported data) provided by the European Topic Centre on Inland, Coastal and Marine waters, and made available at https://www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-8. The dataset presents the available information (localisation of discharge points, link to specific treatment plant, type of receiving area into which the effluent/wastewater is discharged, related waterbody/river basin) on individual points of discharge from treatment plants or collecting systems located in coastal NUTS3 regions, based on data selected from the reporting of Member States as part of the UWWTD implementation. It is available for viewing and download on EMODnet - Human Activities web portal (https://emodnet.ec.europa.eu/en/human-activities). The geographic coverage is: Belgium, Bulgaria, Croatia, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Latvia, Lithuania, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, Sweden, United Kingdom. The description of all attribute fields of UWWTP is given in the Waterbase-UWWTD (https://www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-8/waterbase-uwwtd). Compared with the previous version, this new version has been updated consdiering late deliveries and corrections provided by several countries during 2021 (Waterbase-UWWTD; version 8 publised 19 May 2022).
