The European Water Association (EWA) is an independent non-governmental and non-profit making organisation dealing with the management and improvement of the water environment. It is one of the major professional associations in Europe that covers the whole water sector, wastewater as well as drinking water and water and wastewater treatment related wastes. With member associations from nearly all European Countries, the EWA includes most of the current European Union Member States and others.

The aim of EWA is to provide a forum for the discussion of key technical and policy issues affecting the growing European region. This is done through conferences, workshops, meetings and special working groups of experts all organised on an international basis together with regular publications. EWA informs its members on the development of EU legislation and standardisation and seeks to influence the drafting when appropriate. It has close contacts with the European Commission (DG Environment), the European Committee for Standardization (CEN), the European Environment Agency (EEA) and the European Parliament.

Through this exchange of knowledge the objective of EWA is to contribute to sustainable water management, a safe water supply and the protection of the water and soil environment.

Today, EWA consists of about 25 European national associations each representing professionals and technicians for wastewater and water utilities, academics, consultants and contractors as well as a growing number of corporate member firms and enterprises. EWA thus represents about 55,000 professional individuals working in the broad field of water management.
