This TBM burrowed tunnel has long drained the region's groundwater at an average rate of 416 lit/s. The groundwater is rich in hydrogen sulfide (H2S) gas. The gas reacts with the tunnel humidity and produces an acidic fume that penetrates the tunnel lining and decomposes its concrete and steel reinforcement, as well.
