Sep. 30, 2009

Main Contents

Mitsui & Co., Ltd. ("Mitsui") (Head Office: Tokyo; CEO: Masami Iijima), through its consolidated subsidiaries Atlatec (*1) and SAT (*2), together with the corporate group of ICA(*3), concluded a wastewater treatment service agreement which involves the construction and operation of the biggest wastewater treatment plant in Mexico on September 29th of 2009.

Mitsui's two consolidated subsidiaries, Atlatec, a water/wastewater treatment engineering and construction company located in Mexico, which was acquired by Mitsui in July 2008, and SAT, an investment firm in Mexico wholly owned by Mitsui USA, have invested in 50% of the total shares of the project company ("Project-Co"), which will operate and maintain the wastewater treatment facilities, together with the corporate group of ICA, the largest construction firm in Mexico, which has invested in the remaining 50% of the shares of the Project-Co. (Please refer to the Contract Scheme.)

Project Scheme

Environmental pollution by untreated wastewater is becoming more serious in Guadalajara City, Mexico's second largest metropolitan area (a population of about 3.65 million people). The Project-Co will provide twenty years of wastewater treatment service to the Water Commission of the State of Jalisco ("CEA") by the construction and operation of the biggest wastewater treatment facility in Mexico, with a capacity of 734,400 tons/day.

Mitsui, together with Atlatec and SAT, will meet almost the entire demand for household wastewater treatment in the metropolitan area of Guadalajara City by executing this project and the El Ahogado wastewater treatment BOT project (a capacity of 194,400 tons/day), which is now being executed by Atlatec and SAT pursuant to the agreement with CEA dated December 10th of 2008.

Mitsui has already participated in 9 DBFO projects in Mexico through Atlatec and SAT, such as a wastewater treatment project in Queretaro State and an industrial wastewater treatment project for PEMEX refineries. Mexico is compelled to urgently improve and maintain wastewater treatment plants in many cities, including in Guadalajara. Accordingly, Mitsui will continuously undertake water/wastewater treatment projects which contribute to regional communities and environmental preservation in Mexico and further develop its water business through municipal water/wastewater projects and desalination projects in regions which have water problems, such as in Asia and the Middle East.
