Executive overview
Why this report matters
Summary Insight: SABESP is undertaking an accelerated infrastructure transformation following the completion of its privatisation in 2024. The company must deliver universal water and sanitation services across its contracted areas by 2029 while expanding water availability, reducing distribution losses, extending sewerage networks, increasing treatment capacity, and operating within the regulatory framework established for the URAE 1 Southeast regional concession.
This Our Future Water Intelligence report provides an independent assessment of SABESP’s governance transition, universalisation programme, regulatory framework, capital delivery, water-security strategy, operational efficiency, and long-term environmental obligations.
SABESP plans to invest approximately R$70 billion through 2029 to expand water availability and security, accelerate sanitation universalisation, modernise assets, reduce losses, increase treatment capacity, and meet contracted service obligations four years ahead of Brazil’s federal 2033 deadline.

Decision scope
Questions answered
How did the 2024 privatisation change SABESP's governance?
The transaction transferred SABESP from state-controlled ownership to a dispersed private-capital structure while retaining its stock-market listings and regulated public-service obligations. Governance is now driven by private corporate control, securities-market requirements, the regional concession contract, and ARSESP oversight.
How is SABESP financing its accelerated investment programme?
SABESP combines internally generated cash with domestic and international borrowing, capital-market instruments, and development-finance facilities. The investment programme must be coordinated with regulated tariffs, contractual performance requirements, debt capacity, procurement, and construction delivery.
How does the regulatory framework protect customers and investment?
ARSESP regulates tariffs and monitors contractual service requirements within the URAE 1 Southeast framework. Annual adjustments, periodic reviews, affordability protections, performance indicators, and economic-equilibrium provisions connect permitted revenue with efficient investment and service delivery.
Why are sanitation expansion and water-loss reduction central to the programme?
Sanitation expansion is required to meet the 2029 universalisation commitments and improve environmental conditions in rivers, reservoirs, and urban communities. Water-loss reduction increases the value of existing supply by combining pipe renewal, pressure management, district monitoring, leak detection, metering, and faster repairs.
