Changes in the regulatory and legal framework for Brazil's water and sanitation sector (Law 14,026, July 15, 2020) require competitive bidding for service contracts, even in cases where the provision of services was previously delegated to state-owned utilities under program contracts. The aim of this study was to identify the actors who benefited from these changes to the legislation and assess the social effectiveness of the privatization of water supply and sewerage services in the state of Rio de Janeiro by investigating the auction of services provided by the public utility CEDAE in four blocks comprising 35 municipalities in April 2021. We conducted an exploratory analysis of secondary data and used the systemic integration method to identify the main actors involved in the concession process and the role they played. It is concluded that federal, state, and municipal governments, the Brazilian Development Bank, and the concessionaires have gained from the concessions, while the percentage of low-income populations connected to the sewage collection or drainage network is lower and tariffs are higher in municipalities served by the private sector when compared to the municipalities encompassed by the auction.
