UWWTD data request 2015





The Director-General


To Environment Attachés of Permanent Representations

Brussels, December 2015

ENV.C.2/BR/cg env.c.2(2015)6094021

Your Excellency,

According to Articles 15 and 17 of the Urban Waste Water Treatment Directive (UWWTD, 91/271/EEC [1] ), the Commission has the duty to monitor progress in the implementation of the Directive and to have a better knowledge of the pending projects and measures.

In the context of Article 15.4 of the UWWTD as well as Article 4(3) of the Treaty on the European Union, all Member States are requested to deliver data for the year 2014. In the context of the implementation programme in accordance with Article 17, the information requested by its Implementing Decision [2] has to be provided by 30 June 2016. Concerning national programmes and table 5 of the Decision, the Commission will particularly assess specific measures related to storm water overflows and treated waste water reuse.

The reporting process will be the same as in the past, through a questionnaire and XML formats that were agreed and updated in 2015 after consultation and discussion with MS to integrate Article 17 tables and changes in sensitive areas tables. More details about the reporting process and format are specified in the document attached to this letter (in English).

I would be grateful to receive your replies via the Reportnet [3] system of the European Environment Agency within six months of receipt of this letter.

I would also like to inform you that a specific website has been developed under the SIIF (Structured Information and Implementation Frameworks) pilot project, which can be used by you to prepare your reporting and/or to disseminate your waste water information at national level. It is a free solution that can also help you to implement the INSPIRE and public access to environmental information directives.

For any complementary questions, please contact Benilde Bujarrabal Fernández, phone: (+32)-2-2996863, email: or Bruno Rakedjian phone: (+32) 229-58160, email:

Yours faithfully,

Daniel Calleja
