The national government has moved forward with the privatization of Agua y Saneamientos Argentinos (AySA), the country's main drinking water and sanitation company. Resolution 1198/2025, signed by the Minister of Economy, Luis Caputo, and published in the Official Gazette, marks the beginning of the process that seeks to transfer the company's management to the private sector.
AySA, 90% of whose share capital belongs to the State, provides services in the Buenos Aires Metropolitan Area (AMBA). The official plan contemplates the sale of at least 51% of the shares to a strategic operator through a national and international public tender, while the remainder will be placed on local stock markets.
Legal framework and responsible agencies
The privatization of AySA is framed by Decree 494/2025 and Law 27,742, better known as the Bases Law, which declared the company "subject to privatization." The Temporary Special Executive Unit "Public Companies Transformation Agency" was designated to coordinate the procedure together with the Secretariat of Public Works.
Both agencies must guarantee the continuity of the public drinking water and sewage service during and after the transfer. The concession contract will be drafted by the Secretariat of Public Works, with the participation of the Executive Unit.
