Dear Colleague,

You are invited to provide in accordance with Art. 13 of the Bathing Water Directive 2006/7/EC your national bathing water data for the reporting period 2016 at your earliest convenience but not later than 31 December 2016. Member States are expected to report monitoring results for intestinal enterococci and Escherichia coli, as well as management measures as implemented in the bathing season 2016.

For this reporting obligation 531 ‘BWD - Monitoring and Classification of Bathing Waters’, Reportnet reporting templates for xls or xml files can be downloaded from the Data Dictionary for the Bathing Water Directive 2006/7/EC. These templates enable an automatic QC procedure. Please use these most recent templates as they include changes made to the Data Dictionary. Explanations for all fields are also given in the Data Dictionary.

Additional information is available on the public web-page General help regarding the use of the CDR is available here, as well as BWD-specific documents:

•      How to use Reportnet for BWD reporting for the bathing season 2016 – description of BWD-specific details on how to use the Reportnet/CDR.

•      Guidelines for assessment under the Bathing Water Directive and reporting for the 2016 bathing season – assessment criteria for the bathing season 2016 are described here;

If you need national support for your work with Reportnet, please contact your Eionet National Focal Point. Reporting permissions are to be communicated between WISE national reporting coordinators and

Data delivery

All data files should be uploaded to the Central Data Repository (CDR). Note that BWD folders have been prepared in order to separate deliveries of two different reporting obligations (which have been previously reported to the same or various different folders):

•     Identification of Bathing Waters – obligation 532 (cdr/{Country_code}/eu/bwd/bwd_532/)

•     Monitoring and Classification of Bathing Waters – obligation 531 (cdr/{Country_code}/eu/bwd/bwd_531/)

Please upload the monitoring and classification data into the corresponding folder. If needed, the inventory of identified bathing waters as reported by the beginning of the bathing season 2016 can be redelivered and updated into the corresponding folder.

Automatic quality check (QA)

Once your data files have been uploaded, an automatic QA/QC procedure should be run and a list of errors will be automatically and immediately shown. We kindly request checking the results, correcting problems (if any) and redeliver corrected data. You can find a description of how to import data into CDR, run automatic QA and perform redelivery in the document How to use Reportnet for BWD. A further level of manual data quality checks will be carried out by the ETC/ICM after your release of the 2016 bathing season data.

Consistency of identification codes of bathing waters

Please pay attention to identification codes of bathing waters (BWID, NumInd = AccessKey) and provide a table of the new codes and corresponding old codes in case of code changes. Else, the code changes might result in duplicated bathing waters (i.e. the same bathing water is listed twice, with the old and the new code). To keep consistency of identification codes of bathing waters please check national BWID codes from the previous bathing season stored at the EEA water website stored as Bathing Water Directive - Status 1990 - 2015. Linking data from the old and the new codes is important for enabling continuous time series and assessment under the Bathing Water Directive 2006/7/EC using 4-year assessment periods.

You are very welcome to report WFD water body codes and names for each bathing water. The same codes should be used as in the latest dataset/update of water bodies provided to the EC under reporting for the Water Framework Directive (WFD). The national list of water bodies as reported for WFD is also available on the public BWD help web-page

Bathing water profiles

You are also very welcome to report website links (URLs) of national/regional bathing water portals as well as links of bathing water profiles into “ManMeas” field within BWD reporting template of the Data Dictionary. The most direct URL connection is preferable. Complete URLS should be reported (e.g.: Since some links in the previous seasons were not reported with complete URL, they did not work properly in the interactive viewer. For this reason we kindly ask you to ensure that complete URLs are reported.

Bathing water locations for the season 2017

We also invite you to specify all the waters identified as bathing waters for the season 2017, as indicated by the Bathing Water Directive 2006/7/EC. Following this reporting obligation 532 ‘Bathing Water Directive - Identification of Bathing Waters’, please upload your 2017 locations by the beginning of the bathing season 2017 into the Central Data Repository into a separate folder for 2017 reporting (cdr/{Country_code}/eu/bwd/bwd_532/).
