Cinturão das Águas do Ceará: water security for North-East Brazil

The vast Cinturão das Águas do Ceará development stands as a historic milestone for North-East Brazil. This major water infrastructure scheme is designed to deliver water security to thousands of people who have endured the harsh effects of prolonged drought across the region.

How does the Cinturão das Águas structure work?

This large-scale project brings together modern canals, tunnels and siphons that connect strategic points across the state. The engineering system draws water from the Jati Dam and then channels it onwards, ensuring that water reaches areas repeatedly hit by ongoing scarcity.

With construction progressing quickly, Ceará is moving closer to completing a huge artificial channel. This new corridor is expected to directly support several communities in Cariri, opening up fresh opportunities for social development while boosting the local economy in a sustainable way.

What role does gravity play in moving water?

One of the most striking aspects of the Cinturão das Águas canal engineering is that it can convey water without relying on electric pumping. The flow runs naturally along carefully designed gradients, which sharply lowers the public system’s maintenance and operating costs.

This remarkable engineering work also makes it possible to move an impressive volume of water per second over long distances in the semi-arid interior. As a result, the canals provide the water security Ceará needs to face future periods of extreme dry weather with better planning and fewer worries.

What are the benefits of the integration project?

Linking the São Francisco River to Ceará’s interior brings immediate gains for public urban water supply. This extensive network of canals reduces dependence on water tanker lorries and helps ensure a continuous supply of treated water for families living in the countryside.

Beyond household use, the steady arrival of water strengthens small-scale farming and traditional family livestock rearing. Easier access to water resources enables small rural producers to increase daily productivity in a secure and highly profitable way.

Water Security

Main targets of the Cinturão das Águas

The key aims of this major infrastructure project include:

1. Efficient water distribution to the interior;
2. Reducing the impacts caused by prolonged drought;
3. Secure supply for thousands of Ceará families.

What is the current status of the works?

With more than 90% of the civil works completed, the project is now moving into its final stages of operational testing. Canal and tunnel construction continues at pace to ensure the full functionality of the entire transfer system in a rapid way.

The current schedule indicates the full 145 km section will be delivered soon. This progress reflects a joint effort to consolidate water infrastructure and bring a renewed sense of future prospects for the people of the north-eastern semi-arid region.

The main technical components that make up this major distribution corridor include:

• Concrete canals sized for continuous flow;
• Highly complex technological siphons and tunnels;
• Outflow structures positioned strategically.

How does the project change local life?

A reliable supply of water reshapes the social reality for thousands of families across the semi-arid region. By easing drought conditions, it supports a more prosperous environment and helps new generations remain on their land with dignity and hope for a better tomorrow.

Ensuring consistent water supply also strengthens the foundations for sustainable growth across the entire state. In this way, Ceará becomes an inspiring example of overcoming climatic adversity through large infrastructure projects focused on development.
