Urban Waste Water Treatment Directive, Agglomerations reported under UWWTD data call 2023 - FINAL INTERNAL VERSION, Oct. 2025 (Spatial data)
UWWTD Agglomerations, Oct. 2025 is one of the datasets produced within the frame of the reporting under 12th UWWTD Art.15 reporting period (UWWTD data call 2023).
The Urban Waste Water Treatment Directive (UWWTD) (91/271/EEC) obliges Member States to report data on the implementation of the Directive upon request from the European Commission bi-annually. Reported data include receiving areas as designated under UWWTD, agglomerations, urban waste water treatment plants serving the agglomerations and points of discharges.
Dataset UWWTD_Agglomerations contains agglomerations reported by countries with generated load ≥ 2000 p.e. (or even smaller), including names, coordinates, generated load and information whether the load generated is collected through collecting system or addressed via Individual Appropriate Systems (IAS) or not collected not addressed via IAS.
The dataset is provided in GeoPackage and ESRI File geodatabase formats.
IMPORTANT NOTE: Public access to this data set is restricted due to intellectual property rights. It shall only be used internally by the EEA, its ETCs and subcontractors working on behalf of the EEA.

The directive imposes different reporting obligations (Situation report according to Article 16 and implementation programme according to Article 17). The data presented in the UWWTD Waterbase pertains to Articles 15 and 17 of the Directive, which stipulates that discharges from urban waste water treatment plants and amounts and composition of sludges disposed to surface waters must be monitored to verify the compliance with specific provisions of the Directive.
Some technical insight and familiarity with the terms and contexts used for the implementation of the UWWTD is required to make use of the tables.
By linking the information in the tables on agglomerations, UWWTPs, discharge points and receiving areas it is possible to obtain a complete picture showing what type of treatment is applied to treat waste water generated in specific agglomeration, what is the character of the area (e.g. water body) receiving discharges from waste water treatment plans or collecting systems without treatment.
The content of the table with additional data can be used for further quantitative analyses on emissions from UWWTPs with different types of treatment and various size categories. A QA-document describes a flagging of some of the provided data according to certain criteria. These flags should be considered by the user for specific purposes.
All the tables from Waterbase can be downloaded for use by all stakeholders according to below Rights. Lists and explanation of codes can also be shown and downloaded from Additional information - Code Lists. Link to further details on reporting guidelines is given from below Reporting Obligations.
This metadata refers to the internal dataset which contains all reported agglomerations, including inactive ones. Agglomerations with obviously wrong coordinates were excluded only.
The public dataset excluding inactive agglomerations can be found under the entry "Urban Waste Water Treatment Directive, Agglomerations reported under UWWTD data call 2023 - PUBLIC FINAL VERSION, Oct. 2025" ( https://sdi.eea.europa.eu/catalogue/inspire-pds/eng/catalog.search#/metadata/feb3a7c3-0d59-47b6-9dd4-0a1779a684b2)

Agglomerations data were reported by Member states in tabular format. Spatial position of individual agglomeations was specified by the geographical coordinates fields (longitude, latitude). These tabular data were checked, grouped into a common Pan-European dataset and transformed to the spatial data layer in GIS software. Agglomerations with obviously wrong coordinates were removed.
If the agglomeration coordinates were not reported, given agglomeration was not excluded (= missing information, coordinates are unknown); on the transformation from reported tabular format to the spatial point layer in GIS, records with missing coordinates were not transferred to the points visible in the data layer, of course, but they are available in the attribute table and their coordinates aggLatitude and aggLongitude in the attribute table are NULL.
Tabular data is accessible here: https://sdi.eea.europa.eu/catalogue/srv/eng/catalog.search#/metadata/a55c14cd-aa37-4045-892d-2c3ea36abaff
