Befesa and Agua y Gestión have been awarded the 2.2 million euro maintenance contracts for eleven dams in the provinces of Granada, Cordoba, and Jaen

The Ministry of the Environment has awarded the Agua y Gestión, Befesa Construcción y Tecnología Ambiental, and Ayesa joint venture the two-year contract, extendible to four years, for the maintenance, monitoring and auscultation services at the dams of Bermejales, Bolera, Canales, Cubillas, Colomera, Francisco Abellan, Iznajar, Negratin, Portillo, Quentar, and San Clemente reservoirs.

This contract is part of the activities required to comply with the legislation in force on dam safety matters, which affects all dams that exceed established values as regards height, reservoir capacity, spillway capacity, etc.

These requirements include monitoring and auscultation operations, consisting of complex control systems that enable the behavior of the dam and the terrain, in relation to the previsions, to be known at any given time.

The dams, the operation of which is the responsibility of the Guadalquivir Hydrographic Confederation, were mostly constructed in the sixties and seventies, although the oldest, that of Cubillas, dates back to 1939. Most are loose matter dams (Canales, Cubillas, Colomera, Francisco Abellan, and San Clemente), consisting of stones, gravel, sand, silt and clays that are treated and fall into place through the mechanical compacting procedures of the soil itself, while the gravity and cavity dams are made of concrete.

The services that are to be provided, in addition to the maintenance of the auscultation systems and the monitoring thereof through periodic data collection, also include the conservation and maintenance of the buildings, accesses, urbanization, dams, electric and mechanical installations, and instrumentation, as well as the elaboration of follow-up reports and technical assistance to be given to Facultative Management.
