The São Francisco River diversion in Brazil's outback cost £2.1bn, yet many locals like Maria de Fátima still lack water. This massive infrastructure project was billed as the solution to the sertão's chronic water scarcity, but nearly a decade after completion, questions remain about its success. The concrete canal cuts through the Caatinga scrubland, feeding a reservoir that should provide water to 12 million people, according to the government.
The Promise of the São Francisco River Diversion
The diversion of the 1,700-mile-long river was designed to bring reliable water to the drought-prone north-east. The Paraíba River now receives a steady inflow from the canal, supposedly securing water for agriculture and human consumption. However, for displaced communities like Ferreira's, the reality is different. She lives just two and a half miles from the reservoir but has no piped water, relying on the reservoir for bathing and her smallholding.

Where Has the Water Gone?
A significant portion of the water is lost to evaporation, leakage, and inefficiencies in the distribution network. Additionally, political interests and mismanagement have meant that some communities are prioritized over others. The table below compares the expected versus actual water delivery to key areas:
| Region | Expected Water (million m³/year) | Actual Water (million m³/year) |
|---|---|---|
| Monteiro | 50 | 38 |
| Sertânia | 40 | 22 |
| Rural villages | 30 | 5 |
Such discrepancies highlight the gap between planning and execution. The climate crisis is accelerating desertification, making every drop more precious. The background to this story is set out in Soviet Water Diversion for Cotton Created the Aralkum Desert.
Key Takeaways from the Water Diversion Project
- The project cost £2.1bn and serves 12 million people on paper, but local access remains uneven.
- Displaced communities like Ferreira's often lack basic water connections despite proximity to infrastructure.
- Climate change is increasing drought frequency, putting more pressure on the system.
- Alternative programs like One Million Cisterns have improved access at a smaller scale.
- Transparency and maintenance are critical for large-scale water projects to fulfill their promise.
FAQ
Why did the São Francisco River diversion cost £2.1bn?
The cost covers the extensive concrete canal, pumping stations, and reservoir system spanning hundreds of miles through difficult terrain. Political and logistical factors also drove expenses up.
How many people benefit from the diversion?
The government claims 12 million people receive water security, but many rural communities still lack direct access, as seen in the case of Maria de Fátima Ferreira da Silva.
What are the main challenges facing water distribution in the sertão?
Water loss through evaporation and leaks, uneven political prioritization, and the increasing impact of the climate crisis are key challenges. The region's aridification worsens the situation.
