Water is essential for life and human activities. In addition to the constant increase in water demand, there are problems caused by inefficient governance, such as the discharge of untreated wastewater into rivers and seas, which is aggravated by the limited participation of civil society in decision-making. To face current and future challenges, solid public policies must be implemented, focused on measurable objectives, following planned and predetermined schedules on an appropriate scale, based on a clear assignment of functions to the competent authorities, and subject to periodic monitoring and evaluation. The Institutional Analysis and Development framework proposed by Ostrom made it possible to identify gaps in the existing governance, and to establish actions that could strengthen the institutional framework with the active participation of social actors, in order to achieve an effective conservation of water resources in southern Ecuador. The present study determined that regulations are not coherent with the conflict, the design of policies, and the effects of decision-making. The formal rules for wastewater management are not applied, and there is an incipient citizen participation, as well as disarticulation in institutions responsible for wastewater management. Recommendations were made to strengthen the institutional framework and governance of wastewater.
