A consortium of Mexican, Spanish and Japanese investors has won a $726 million contract to build and operate Mexico’s – and one of the world’s – largest wastewater treatment plants.
 
Mexican construction firms IDEAL and ICA, together with Spain’s Acciona Agua and a subsidiary of Japanese investor Mitsui & Co. will build, operate and transfer (BOT) a wastewater treatment plant in Atotonilco, about 60 kilometres north-east of Mexico City, for a period of 25 years. The plant will be able to handle about 3,600,000 tons of wastewater per day and aims to treat 60 percent of the wastewater emitted by Mexico City.
 
The project will be funded with a grant from Mexico’s National Infrastructure Foundation (FONADIN), in addition to a commercial bank loan and sponsor equity.
