Data
The dataset contains data reported by Member States under UWWTD reporting obligations: UWWTD implementation (Article 15) and UWWTD National Implementation Programme (Article 17). The dataset consists of tables containing information on: reported period, agglomerations, urban waste water treatment plants (UWWTPs), links agglomerations – UWWTPs, discharge points, receiving areas, and (at Member State level) sludge handling and treated waste water re-use. Relevant codelist tables (big cities, NUTS, common list of values) are included as well. Article 17 tables are distinguished by the „Art17“ prefix in the table name.
[+] Show table definition
Definition of the tables and fields creating the published dataset is available in the Data Dictionaries (excluding the table T_UWWTPS_emission_load and codelist tables T_BigCity, T_LOV and T_NUTS – their definition is provided at the end of this section). Hyperlinks to the Data Dictionaries are embedded to the table names below:

T_UWWTPs_emission_load
Table contains additional data on incoming and discharged loads of organic matter and nutrients, provided by some Member States beyond the scope of UWWTD compliance. The data can be linked with the T_UWWTPs for further characteristics for the specific plants. A QA flag for some records relates to certain criteria and should be considered by the user for specific purposes. Field uwwState is related to the records having value State in the codelist table T_LOV, field lovName. Fields uwwCode and uwwName are related to the table T_UWWTPs.

Methodology:
Reported data were uploaded by countries on CDR, quality assured by the Reportnet Automatic QA system, technically accepted by UWWTD helpdesk team and afterwards automatically harvested from CDR to the UWWTD database in EEA Common workspace. The final pan-European dataset (EU 27 + GB) was exported from the UWWTD database as MS Access database file.
Data sources
Datasets stored in reportnet by member state reporters. Version 8, date of delivery (date sent to the Data Service): 20/11/2020.

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.
