By means of the Action-Participation Research method, the articulation of a local social movement which faced global fights against macro projects for the usurpation of the water resource and fragile ecosystems which were affected because of the extension in the Aqueduct in the Metropolitan area of Bucaramanga, is systematized. The movement has its origins in the area of Piedecuesta (Santander, Colombia), and as a network (Cohen & Arato, 2000; Melucci, 2002) it has extended to different areas to the municipalities of Guaca, Tona and the Metropolitan Area of Bucaramanga. For this specific case of the Defenders of the Water Cohen and Arato's (2000) theories are applied in the reconstruction of civil society using two of the great paradigms of social movements: mobilization of resources and new social movements, this way, making contemporary social movements easier to understand. The action framework of the Defenders of the Water struggle is given in the 1991 Constitution, in which a Social State of Rights immersed into a market economy (Jimenez, 2008) is postulated. Thence it follows the legislative flow such as Law 134 of Citizen Participation, which regulates Town Meetings, and Law 99 from 1993 about Environment which, in article 72, refers to Environmental Public Audiences as mechanisms which are used by the Movement above mentioned as struggle instruments. This article allows to glance the role of professionals in the social movement, the dialogue of knowledge between popular knowledge and scientific knowledge which structure the Movement, the role of non-governmental organizations in the logics of the Neoliberal State (Escobar, Alvarez & Dagnino, 2001). The creation and evolution of a social movement will be shown, as well as its transformation, its achievements such as the solidarity attained, the l cultural policy generated both within civil society and within the State., The calls to symbolic and counterpublic spaces (Escobar, Alvarez &Dagnino, 2010), the pacific demonstrations of 200, 1200, 2000 and 5000 people from urban and rural origins, facts that made the macro project stop at a regional level. Besides, collective and individual defeats in scenarios of conflict, and also to relate how, wanting to extend the struggle to a national context, fails. This is to say it leaves as a question the lack of articulation of a social environment movement at a national level that faces local and regional environmental conflicts.
