Empresas ICA, S.A.B. de C.V. announced that it signed a MXN 1,139 million contract with the National Water Commission (Conagua) to construct the General Canal Tunnel in the Chalco Valley. The contract was awarded through a domestic bidding process, and will be executed over 38 months. The project is an integral part of Conagua's long-term plan to end seasonal flooding in the Mexico City metropolitan area.

The 7.9 km, 5 meter diameter tunnel will run parallel to the General Canal, from the Parada del Toro pumping station to the La Caldera pumping station. The project will use an EPB boring machine for the excavation and includes fabrication and installation of the pre-cast concrete segmental lining, installation of the finish lining and covering, and construction of four 12 meter diameter drop shafts, with an average depth of 25 meters each.
