Olomos Breakthrough

The Olmos aqueduct in the high Andes will transfer water from the Atlantic basin to the Pacific basin to irrigate one of the driest regions of Peru. Breakthrough of the final 12.5 km-long section was achieved by a 5.3 m-diameter Robbins main beam TBM on 20.12.2011 after an epic drive through bursting rock using novel support and operating techniques.
