The Argentine National Government published Resolution No. 704/2026 of the Ministry of Economy (Official Gazette, May 15, 2026), authorizing the call for National and International Multi-Stage Public Tender No. 504/2-0003-LPU26 for the privatization of Agua y Saneamientos Argentinos S.A. (AySA).
The transaction involves the sale of 90% of the State’s equity stake to a single Strategic Operator, with bids due by August 27, 2026 via CONTRAT.AR.
AySA holds the exclusive concession for the provision of potable water and sewerage collection services across Buenos Aires City and 26 districts of Greater Buenos Aires — serving approximately 14 million people, one of the largest water utilities in Latin America.
The tender process and the new concession fall under the new Regulatory Framework for the provision of public water and sanitation services (Law No. 26,221, as amended by Executive Decree of Necessity and Urgency No. 493/25). This new regulation aims to achieve better financial, economic, tariff and institutional conditions, as well as to satisfy investment needs and enhance service quality.
