A series of projects to improve drainage in the valley are currently underway, including the construction of the Churubusco-Xochiaca drainage tunnel.

ICA, in association with its subsidiary Construcciones y Trituraciones, won the contract to build the tunnel with a bid of 2.57bn pesos (US$197mn). Earlier this year, it won a tender for construction of the Canal General drainage tunnel with a bid of 1.14bn pesos.
