Dam of Cohilla.
The Cohilla reservoir, located southwest of Cantabria (Spain), is an arch-type dam built in 1950 covering an area of 450 hectares. This dam, owned by Endesa, has a volume of 12 hm³, retaining the waters of the Nansa river. Maquigestión Europa, on assignment from Endesa, carried out the vertical preparation work on the dam wall. In spite of the complexity of the job, total accessibility to the entire repair zone was achieved. Thanks to these scaffolding systems, the projected works at the dam are being carried out successfully.
