Overview
- The Economy Ministry, which on Friday published Resolution 704/2026 in the Official Gazette, opened a multi-stage national and international tender on the CONTRAT.AR portal to transfer 90% of AySA.
- The pliego sets a calendar with queries accepted until August 12 and offers due August 27, when the technical bids will be opened in an online public act.
- Only operators with large-scale water and sewer experience and strong finances may compete, and the sale carries no minimum price even as market estimates put the deal near US$500 million.
- The winner will run the AMBA water utility under a 30-year concession with a possible 10-year extension, with investment duties, tariff update rules and ERAS oversight, while workers keep a 10% stake through a participation program.
- AySA serves about 14–15 million people in Buenos Aires City and 26 suburbs, and officials cast the sale as part of a broader privatization drive targeting roughly US$2–3 billion this year with AySA proceeds earmarked for debt payment.
