We have achieved important transformations that today reflect in a higher standard of living

The year of 1993 saw the launch of a genuine revolution in the supply of water and wastewater sanitation in Portugal. As a result of membership of the then European Economic Community, there was the scope for implementing a corporate management structure led by Águas de Portugal in partnership with the municipalities.

Through supra-municipal solutions, returning economies of scale and enabling greater levels of efficiency in the utilisation of resources, the group proved able to attain the objectives of raising water quality standards alongside public service levels with Portugal now ranking among the European Union countries attaining the best levels of environmental performance.  

Today, Águas de Portugal group companies provide services, directly or indirectly, throughout all of mainland Portugal and across the fields of water supply and wastewater sanitation. The group runs further operations in the renewable energies and shared service sectors as well as its ongoing engagement in international markets.

Taking into account guaranteeing all citizens continuity, universality, quality and sustainability in the provision of these essential public services, the group sets about its mission and heading down a path enabling a more robust and sustainable future due to the excellence of the services rendered, its high level environmental performance and constantly deepening it technical, economic and financial levels of efficiency.
