1926 – 2026

History of an institution at the pace of its time

The CHE and water management in every era

The Confederación Sindical Hidrográfica del Ebro was established on March 5, 1926, to comprehensively manage the Ebro basin according to the principle of basin unity.

This approach made it possible to organize water regulation and management beyond administrative boundaries, in an area which includes territories of nine autonomous communities. It also includes the Principality of Andorra and areas of the French department of Ariège, in the upper Segre basin, since the delimitation follows hydrological criteria.

More information about the centenary

This timeline brings together, in chronological order, the main milestones of this evolution from 1926 to the present day.

1879 - 1926

The dream of a common river.
The idea that gave rise to CHE

The vision of comprehensive management of the Ebro River is born. From the Water Act (1879) to the founding of the CHE, through Joaquín Costa's regenerationism and Manuel Lorenzo Pardo's confederate model.

1936 - 1939

Divided waters.
The Civil War and the fragmentation of the CHE

During the Civil War, the CHE was divided and its functions were paralyzed. The institution suffers damages, duplications and a temporary loss of operational efficiency.

1940 - 1975

A contained channel.
Hydraulic expansion in times of reconstruction

The works projected during the founding period are consolidated, more than forty reservoirs and large canals make Spain enters its developmental era. The CHE leads the hydraulic policy of the Franco regime with a technical and centralized model that transforms the landscape and irrigation.

1976 - 2000

The democratic awakening of the river.
Towards a new water awareness

The democratic transition and the 1985 Water Law transformed the management model, incorporating public participation, environmental sustainability and water quality control.

2001 - 2026

A river to take care of.
The century of agreement

The Water Framework Directive consolidates river basin planning. Strategies to tackle climate change are being implemented, such as risk plans, river restoration and the Ebro Resilience and Ebro Fluye programmes.
