The Comisión Nacional en Defensa del Agua y de la Vida (CNDAV), a broad coalition of social and political organisations, successfully campaigned to include the right of access to drinking water and the right of an efficient sewage system as fundamental human rights in the Uruguayan constitution. Since the successful plebiscite, the CNDAV stands up for the definitive cancellation of the concessions of Suez Lyonnaise des Eaux and Aguas de Bilbao which have privatized the delivery of water and sewage services in Uruguay.
