E-WAter is the new electronic journal of the European Water Association (EWA). E-WAter is specifically targeted at European practitioners and researchers by providing a forum where articles presenting and discussing technical views and experiences of European authors in every domain of water management may be published. Every topic within water management can be interesting for the wide scope of the EWA audience: design and construction procedures, O&M, monitoring, legislation, etc. concerning natural waters, drinking water, wastewater and related wastes. Although English is the generally adopted language, our journal is prepared to accept a few articles in other languages, provided that an extended abstract in English is supplied and the subject is recognised as outstanding European interest. Prior to publication, proposed articles are reviewed by two referees from a network of European experts who form the Communication Committee of the EWA. Due to the easy access to an e-journal, articles do not need to be published at regular intervals. However, publishing frequency aims at a monthly publication of one paper.
