Water quality monitoring 40 metres below the sea bed

Natural groundwater collected around the tunnels operated by Eurotunnel is continuously monitored before being pumped to the coast and discharged into the sea. Six multiparameter water quality monitoring systems have been custom-designed by HACH LANGE to ensure that there is no potential for harmful water to enter the pipelines.
