Environmental complexity
Environmental protection was taken into consideration from start to finish throughout the implementation of the project.
During the project, we mapped the seabed in order to place our anchors in the right places and avoid surprises during digging periods. Environmental aspects were respected by the teams during sensitive work in Lake Memphremagog and mitigation measures had been planned upstream and identified in the plans and specifications.
These are mitigation measures that have been put forward by our teams to minimize the impacts of noise and vibrations from blasting and hammering. Indeed, an air curtain (a flexible perforated pipe with an air compressor placed at the bottom of the lake which reduces the speed of dispersion of sound waves and the impact of shock waves) makes it possible not to disturb the fish and the marine fauna was also set up for jackhammer work.
