Sabesp is the largest sanitation company in Brazil and one of the largest in the world. We provide water, sewage collection and treatment to 375 municipalities in the State of São Paulo. We supply 28.7 million people with water and 25.5 million people with sewage collection every day.

Our history began in 1973, with the merger of public companies or companies controlled by the State of São Paulo, linked to basic sanitation. Initially, Sabesp incorporated companies that provided services in the Metropolitan Region of São Paulo, Baixada Santista and Vale do Ribeira.

More than 50 years of work and dedication have brought us to this point and made us responsible for approximately 30% of the investment in basic sanitation made in Brazil. For the period 2024-2028, approximately R$47.4 billion should be invested, with a focus on expanding water availability and security.

In 2023, we reached another important milestone: Sabesp won the bid to manage Olímpia’s sanitation system. It was the first concession the Company won in its history in a competitive process.

Sabesp also operates as a minority shareholder in three other companies that provide water supply, sewage collection and treatment services, as well as six others in the energy, paving and other sanitation services sectors.

We understand that our work plays an essential role in society and is of enormous importance in regenerating the environment. We also do not lose sight of the need to be an example of solidity, transparency and integrity in our governance, both for the market and for society in general. We continue to evolve and face challenges to ensure a better world for future generations.

Sabesp’s common shares are traded in the Novo Mercado Brasil, Bolsa, Balcão (B3) segment under the code SBSP3 and on the New York Stock Exchange (NYSE), in the form of American Depositary Receipts (ADR Level III), under the code SBS.
