Tunnel Emisor Oriente will be one of the largest wastewater tunnels in the world. With a total length of 62 km and running up to 200 m below ground level, the tunnel will significantly reduce the risk of flooding in Mexico City improving the safety and well-being of the inhabitants. The new tunnel will add about 150 cubic meters of water per second (5,300 ft3/sec) once completed. TBM type:1 EPB Herrenknecht + 1 EPB Robbins; external diameter:8.7m;
