Mexico's Atotonilco wastewater treatment plant project in Hidalgo state is currently at the detailed engineering stage with excavation work beginning, ICA CFO Alonso Quintana said in a conference call.
ICA (BMV, NYSE: ICA) is part of a consortium lead by compatriot firm IDEAL, which will build and operate the US$710mn plant.
The facility is slated to be the world's largest wastewater treatment plant, with a maximum capacity of 4.3Mm3/d, BNamericas reported previously. The plant will treat 60% of Mexico City's wastewater which is to be later used for irrigation.
ICA is currently involved in five water concession projects, according to Quintana.
"The Acueducto II [potable water pipeline] in Querétaro started operation in January, meaning that we now have two operational water projects. The other three are under construction," Quintana said.
The Querétaro project required an investment of some 2.85bn pesos (US$237mn) and will provide 47.3Mm3 of potable water for state capital Querétaro, increasing replenishment of the Querétaro aquifer by an estimated 7Mm3 annually.
ICA is also looking to expand its presence in the region as economies rebound in countries such as Colombia, Panama and Peru, said the executive.
"The projects we are mostly seeing right now have to do with underground work in which we are very specialized as you know here in Mexico, where we are building the Túnel Emisor Oriente and Túnel Río de la Compañía and many others," Quintana added.
