(43)Directive 98/83/EC did not set out reporting obligations for small water suppliers. To remedy this and to address the need for implementation and compliance information, a new system should be introduced in this Directive whereby Member States are required to set up, keep up-to-date and make accessible to the Commission and the European Environment Agency (‘the EEA’) data sets containing only relevant data, such as exceedances of parametric values and incidents of a certain significance. This should ensure that the administrative burden on all entities remains as limited as possible. To ensure that the appropriate infrastructure for public access, reporting and data-sharing between public authorities exists, Member States should base the data specifications on Directive 2007/2/EC and its implementing acts.
