A water utility's loan was priced on performance, not just infrastructure
IFC structured its financing for a Brazilian utility's river restoration program with pricing tied to sewage connection targets. That structure, not the loan size, is the more exportable part.

Retrospective analysis of November 2024. Published August 2026.
IFC announced on 19 November 2024 a sustainability linked loan of up to BRL 1.06 billion, roughly $184 million at the time, to Sabesp, the water utility serving Sao Paulo state, to support its Integra Tiete initiative restoring water quality along the Tiete River. The loan carries a ten year tenor and pricing incentives tied to specific performance targets, increasing the share of households connected to sewage collection and treatment in the Guarulhos and Perus service areas, expected to reach more than 360,000 residents. The financing followed IFC's 2022 blue loan to the same utility and forms part of a larger financing package assembled around the Integra Tiete program.
The Signal
IFC's November 2024 sustainability linked loan to Sabesp, up to BRL 1.06 billion, prices interest rate incentives against sewage connection and treatment targets in Guarulhos and Perus rather than against generic ESG metrics.
Why It Matters
A sustainability linked structure that prices against a specific, auditable operational target, households actually connected to treatment, is a materially different underwriting proposition than one priced against a broad ESG score. The former is verifiable against utility connection data. The latter frequently is not.
The System Connection
River restoration and sewage connection are the same infrastructure problem viewed from two ends, and financing that prices the connection metric directly is, in effect, financing the river outcome without needing a separate environmental instrument to do it.
Capital Implication
The specificity of the performance metric, not the loan's size, is what would make this structure replicable for other utilities and other multilateral lenders evaluating water infrastructure in emerging markets.
What We Are Watching
- Connection rate progress in Guarulhos and Perus against the loan's performance targets.
- Whether IFC or other DFIs replicate connection linked pricing on subsequent water utility financings.
- Additional tranches or co-financing added to the broader Integra Tiete package.
