Subject: Member States’ data sets under the recast Drinking Water Directive

Article 18.1 c, d, and e (exceedances, incidents and derogations) – transfer into

Reportnet 3

To the Members of the recast Drinking Water Directive Expert Group

Dear members of the Drinking Water Directive Expert Group,

We would hereby like to invite you to submit your national data sets in relation to the

monitoring results and information required under Article 18.1 (c), (d) and (e) of the recast

Drinking Water Directive 2020/2184 on the quality of water intended for human

consumption to ensure that the Commission, the EEA and the European Centre for Disease

Prevention have access to these data sets.

The transfer of data sets will take place through the Reportnet 3 platform. The first data

sets transfer, covering the period 12 January 2023 – 30 June 2024, is due by 31 March

2025. Following this first data sets transfer, annual data sets transfers will be requested by:

• 12 January 2026: MS data sets covering period 1 July 2024 – 30 June 2025

• 12 January 2027: MS data sets covering period 1 July 2025 – 30 June 2026

• Etc.

The reporting obligation (ROD 832) of the recast Drinking Water Directive (DWD) under

Article 18.1 (c, d, e) requires Member States to set up, and update annually, data sets on

exceedances, incidents, and derogations. The reporting information is described in the

recast DWD as follows:

• For exceedances a data set containing monitoring results, in cases of exceedances of the

parametric values set out in Parts A and B of Annex I, collected in accordance with

Articles 9 and 13 and information about the remedial actions taken in accordance with

Article 14.

• For incidents a data set containing information on incidents relating to water intended

for human consumption that have caused a potential risk to human health, regardless of

whether any failure to meet the parametric values occurred, that lasted for more than 10

consecutive days and that affected at least 1 000 people, including the causes of those

incidents and remedial actions taken in accordance with Article 14.

• For derogations a data set containing information on all derogations granted in

accordance with Article 15(1), including the information provided for in Article 15(2).
