The World Water Council is a non-profit organisation regulated according to the French law of July 1, 1901, known as "Association Loi 1901".

    The ultimate authority of the World Water Council is the General Assembly of Members. They are governed by its Constitution and By-Laws.

    The General Assembly meets at least once every three years in ordinary meetings and as needed in extraordinary meetings.

    The General Assembly elects and appoints a maximum of 35 members to the Board of Governors in accordance with the Constitution and By-Laws. The City of Marseille as host city holds a permanent seat on the board.

    The Board of Governors in turn elects its President, who names a Bureau composed of a Vice-President, a Treasurer, and other members.

    The Bureau and the Executive Director are responsible for the management of World Water Council operations and for decision-making between Board of Governors meetings.
