By Brazil Stock Guide – The government of São Paulo is opening a new sanitation front to cover a large part of the territory left outside Sabesp’s network. UniversalizaSP entered public consultation on Monday, April 27, with planned concessions in 146 municipalities not served by the company — equivalent to about 54% of the 275 cities in the state outside Sabesp’s service area. The program foresees R$ 29 billion in resources by 2033 and R$ 100 billion by 2060.
The numbers help frame the scale of the project. São Paulo has 645 municipalities. Sabesp serves 371 of them. UniversalizaSP targets 146 of the remaining 274, or 22% of all municipalities in the state. The initiative is expected to benefit around 6 million people through expanded access to treated water, sewage collection and treatment, as well as measures to strengthen water security and resilience.
Subsidized concession
The structure will be a subsidized common concession. In practice, the private sector takes over operations, while the state may provide funding when needed to ensure the economic viability of the contracts and preserve tariff affordability.
The program also includes a social tariff for low-income families and transfers to municipalities through Municipal Funds for Environmental Sanitation and Infrastructure.
Regional blocks
The model will follow a regionalized service structure. Municipalities will be grouped into blocks, based on criteria such as river basins, shared infrastructure and potential scale gains. The final design of the lots and auction rules will be defined after the public consultation.
The expected timetable includes a 30-day public consultation, five regional hearings, publication of the tender notice in the third quarter and an auction in the fourth quarter. The possibility that a single operator may win more than one block increases the potential for synergies — and helps explain Sabesp’s natural interest in assessing the project.
A test of appetite
UniversalizaSP comes at a time when Brazil’s sanitation sector combines a huge need for capital, still-high interest rates and more selective investors. São Paulo’s package tries to offset that equation with scale, public subsidies and the promise of regulatory certainty.
The auction will also test whether there is appetite beyond Sabesp. The São Paulo government argues that the project does not directly compete with other sector agendas, such as the privatization of Copasa, because it involves a different model and a different type of risk. In practice, however, capital, engineering capacity and qualified operators remain finite resources.
