São Paulo turns to IFC for guidance on Sabesp’s next phase

The government of Brazil’s São Paulo state has sought advice from the International Finance Corporation (IFC) as it considers the next stage in the development of Sabesp, the state’s largest water and sanitation company. Officials say the World Bank Group’s private-sector arm is viewed as the “natural” partner to conduct technical studies, highlighting the importance of attracting investment while maintaining essential public services.

A strategic partnership under consideration
According to officials familiar with the discussions, São Paulo believes the IFC possesses the expertise needed to assess potential investment models, operational improvements and long-term financing options for Sabesp. The move reflects the state’s ambition to modernise water infrastructure while ensuring that future expansion remains financially sustainable.

An aide involved in the process described the IFC as the “natural” institution to undertake the necessary studies, citing its extensive global experience advising governments on public-private partnerships and infrastructure investment.

The discussions do not represent a final decision on Sabesp’s future ownership or governance structure. Instead, they mark the beginning of a technical evaluation intended to identify options that could improve efficiency, expand service coverage and attract long-term private capital.

Sabesp remains central to Brazil’s infrastructure
Sabesp is one of the world’s largest water and sanitation companies, providing drinking water and wastewater services to millions of residents across São Paulo state. The utility plays a critical role in Brazil’s largest regional economy, making any proposed reforms closely watched by investors, regulators and the public alike.

Improving water infrastructure has become an increasing priority as Brazil seeks to expand sanitation coverage, reduce water losses and strengthen resilience against climate-related pressures, including prolonged droughts and extreme weather events.

Supporters argue that greater private-sector participation could accelerate investment and technological innovation. Critics, however, caution that any changes must preserve affordability, universal access and public accountability for essential services.

The IFC’s growing role in infrastructure finance
The IFC has become an increasingly influential adviser on infrastructure projects across emerging markets, providing technical expertise alongside financing and risk assessment. Rather than promoting a single ownership model, the organisation typically evaluates a range of alternatives designed to balance commercial viability with public policy objectives.

Its involvement often helps governments prepare projects that can attract institutional investors while maintaining appropriate regulatory safeguards and environmental standards.

For São Paulo, working with the IFC could also strengthen international investor confidence by demonstrating that any future reforms are based on transparent, independent analysis rather than political considerations.

Balancing investment and public interest
The future of water infrastructure is becoming an increasingly important issue worldwide as cities face growing populations, ageing networks and mounting climate challenges. Access to capital is essential, but so too is maintaining reliable and affordable public services.

São Paulo’s decision to consult the IFC illustrates the broader trend of governments seeking specialist expertise before undertaking major infrastructure reforms. Whether the outcome leads to additional private investment, operational restructuring or new financing mechanisms, the process is likely to influence debates far beyond Brazil.

As global demand for resilient infrastructure continues to grow, the way governments balance public responsibility with private capital is becoming one of the defining policy questions of the coming decade. The studies commissioned for Sabesp may therefore serve not only as a roadmap for one utility company, but also as a model for future infrastructure partnerships across emerging markets.
