Water Banks in Mexico are water resources management tools, which aim to contribute towards ensuring the sustainability of the resource. The present document refers to the normative and policy framework in Mexico that supports the operation of Water Banks, and the need to consider the trends in the transfer of rights and their future perspectives, in combination with other elements of water policy. In order to outline the institutional design of these bodies, international experiences were reviewed which allowed the operation of similar figures in other regions to be studied, reaching the conclusion that for the case of Mexico it was essential first and foremost to attend to the legal and administrative regime for water, considered as a public asset and therefore the responsibility of the Federation, in order to provide Water Banks with a public nature. The raison d'être of Water Banks, the services they provide and their main advantages, among which it is worth mentioning the integral and specialized advice to the users of the nation's water resources, both regarding the hydrological conditions of a region and the procedure for the three means of transferring rights; the openness of information for appropriate decision making, certainty and transparency are fundamental aspects of their operation. These bodies will continue to develop in order to increase the activities they carry out, heightening the efficiency in the transfer of rights, discouraging the informal market and generating a greater acceptance from the users of the nation's water resources. The analysis of information and the management of computing tools which facilitate the aforementioned are part of the activities that will be intensified so as to achieve the consolidation of Water Banks in Mexico.
