The 2030 Sustainable Development Goals (SDGs) reinforce the central role of organizations in the implementation of solutions that promote sustainability. Similarly, there is a direct link between society’s well-being and the management of water resources. Thus, water companies have a central role in defining targets and programs focused on achieving these goals. This research aims to analyze the incorporation of the SDGs in the Portuguese water sector and evaluate whether the incorporation varies with the management model of each organization. Likewise, it is also intended to compare these results with those observed at international level. By examining the existence of a management model effect in the integration of the SDGs, the paper contributes to the formulation of adoption policies.
