On the final stretch on the Almudévar reservoir build

Sacyr Engineering and Infrastructure tackles the final build works on this project aimed at enhancing the irrigation canal systems in Huesca, Spain.

We are in the final stretch of the construction of the Almudévar reservoir (Huesca, Spain), which will contribute flow to the irrigation system of Alto Aragón.

Currently, the professionals at Sacyr Engineering and Infrastructure are working on the automation of the monitoring system, electrical connections, plantations, archaeological excavations, construction of a hermitage, urbanization, and roadworks. After the completion of the project, the commissioning phase will begin, involving the filling of the reservoir.

More than 120 people have worked daily in the joint venture led by Sacyr Engineering and Infrastructure, along with Lantania, Vías y Construcciones, and Sogeosa. The project's budget is 113 million euros.


Disassembly of a medieval wall

The operation has already started disassembling the medieval wall of the old hermitage of Santo Domingo, under the supervision of Cultural Heritage. The wall will be relocated to a hill to be reassembled in a new hermitage that will be built safe from flooding. Meanwhile, archaeological excavations are underway at the Morrón del Villar site.

The site consists of a core of defensive structures around a tower of Islamic origin, a Romanesque church built from the 12th century onwards, and, around this complex, a series of medieval Christian houses that were likely abandoned due to demographic crises in the 14th century.


Capacity of 169 cubic hectometers

The Almudévar reservoir will have a capacity of 169.7 cubic hectometers and will receive the surpluses from the Gállego and Cinca rivers. The reservoir is closed with two dams, for which more than 7.5 million cubic meters of materials, mostly argillites, have been used. In total, it will flood more than 1,152 hectares.

The conveyance channel has a length of 1,300 meters, transporting water to a reversible station equipped with six pumps, plus a seventh in reserve. The station's design flow is 24 m³/s, conveyed to the reservoir through two parallel pipes of 2,500 mm in diameter. Additionally, the station will have two 5MW turbines to generate electrical energy from the released water.
