The main objective of the study is to support a possible revision of the EU drinking water policy and the current Drinking Water Directive (DWD).
The objective of this Directive is the following: “to protect human health from the adverse effects of any contamination of water intended for human consumption by ensuring that it is wholesome and clean. The general obligation of the DWD is that Member States shall take the measures necessary to ensure that water intended for human consumption is wholesome and clean, that it complies with the requirements of this Directive, and that the measures taken to implement this Directive in no circumstances have the effect of allowing, directly or indirectly, either any deterioration of the present quality of drinking water.”
In order to achieve the main objective of the study, two main study parts, together consisting of eight tasks, will be executed.
- The first part of the study covers an ex post evaluation of the Drinking Water Directive and drinking water policy to assess whether the legislation is fit for purpose and achieving its objectives. This ex post evaluation will cover the key performance dimensions of an ex-post public policy evaluation, including: effectiveness, efficiency, EU value added, coherence and relevance.
- The second part of the study consists of an ex ante impact assessment of future policy options for renewing the Drinking Water Directive. In this assessment a baseline scenario will be developed against which different possible alternative policy scenarios will be assessed in terms of environmental, health, social and economic impacts. The ex-ante impact assessment of different policy options is preceded by a dedicated task (Task 4) scoping and testing Drinking Water Health Risk Assessment – the outcome of this task feeding into the ex-ante impact assessment.
Next to these two main parts, two horizontal organisational tasks will be carried out: Namely, the supporting of the policy development process in its external (mobilising stakeholders, consultation) -and internal components (assistance to the Impact Assessment Board process).
