Canutillar - Hydro

Aquatic Sciences Inc reports it has recently completed a challenging underwater tunnel inspection for Empresa Nacional de Electricidad S.A. Using an underwater remotely operated vehicle, they inspected the intake tunnel for the power plant, locating and delineating a collapse from which debris was impeding the water supply to the turbines and threatening the electricity supply to the district. The Canutillar hydropower station draws water through a 7 km-long tunnel from Lago Chapo where levels have decreased over 20 m from normal due to ongoing drought.
