The privatization of AySA and the defunding of ACUMAR threaten the sanitation of the Matanza-Riachuelo basin.
Eighteen years ago, the Supreme Court issued the historic Mendoza ruling, obligating the national government, the Province, and the City of Buenos Aires to address the severe socio-environmental situation of the Matanza-Riachuelo basin. The goal was to ensure access to water, sanitation, and public health for more than 4 million people.
However, at the end of 2024, the Court closed the case despite most goals remaining unmet. The ACUMAR remains active but without sufficient institutional or budgetary support.
