The hydraulic heritage and water culture in Ibero-America result in a man-made cultural landscape, century after century, where the legacies of several peoples are superimposed. Water is here an element of landscape differentiation and constitutes, therefore, as a distinctive mark in the territory and local memory. The approach to the theme of water from the patrimonial point of view as a material and immaterial good, whose cultural manifestations, derived from its use and application by the peoples, require efforts for its conservation and diffusion. In this context, this work intends to understand the past, present and future of Water Heritage and Culture in its interrelationship with multiculturalism and to promote the investigation of the processes of constitution of memory, identities and local values in Ibero-America. "Claiming water as a world heritage and also as a fundamental human right" is a statement included in the European Union's 2000 Water Framework Directive which serves as a motivation in the presentation of this work highlighting the patrimonial nature of water associated with culture of the people. Water as patrimony is an inexhaustible subject of studies that exceeds the pretensions of this work. The approach to the theme of water from the patrimonial point of view as a material and immaterial good, whose cultural manifestations, derived from its use and application by the peoples, require efforts for its conservation and diffusion. This work will be supported by the research characterized by the difficulty to find the information and to deepen the knowledge related to the water heritage and culture. The explanation lies in the scarcity of materials elaborated on this subject and the difficulty in accessing the respective files and sources. The cultural heritage associated with water is immense. There are innumerable objects associated with water heritage, not least the offices of those who work with this resource in traditional occupations, which only remain in the memory of older people or in cultures that keep their traditions alive. For centuries, human intervention has harnessed the resources and natural environments related to water, resulting in a series of high quality heritage elements that contain important cultural, environmental, landscape and socio-economic values. The consideration of water as heritage includes both material culture: objects, technologies, places, infrastructures ... and the immaterial culture that has been appearing throughout history. Water forms part of the territory. It determines the so-called landscapes of water, defined by the physiognomy of the territory with its natural and anthropogenic elements linked to the emotions that awaken its contemplation. Water landscapes have gained notoriety and, at times, exclusive spatial prominence, given that they are cultural footprints present in many of the municipalities of the Ibero-American countries that are still less well perceived and considered by social collectives. The development of a civic conscience on the conservation of water heritage and culture, which presses to declare them as goods of Community interest and to include them in the heritage of the Ibero-American regions, is therefore absolutely necessary and falls within the scope of this work
