Riachuelo environmental restoration system – Lot 2

Name of Project:
Riachuelo environmental restoration system – Lot 2


Country:
Argentina

Total value:
$215 million

Fisia Italimpianti of the Salini Impregilo Group has acquired a contract worth $215 million to build Lot 2 of the Riachuelo system in Buenos Aires, Argentina, a mega engineering and infrastructure project to reduce pollution in the Riachuelo River, the most polluted in the country.

The new project will see Fisia Italimpianti develop, within a 36-month period, a pre-treatment wastewater plant and accompanying pumping stations with a capacity of 27 cubic metres per second that will make it one of the biggest plants of its kind in the world.

The project is the second of three lots of the Riachuelo system that will contribute to improving the severe environmental conditions of the Matanza Riachuelo River Basin, guaranteeing flexibility and safety to the water purification system of Buenos Aires and having a direct impact on the health and quality of life of its 4.3 million residents.

To be completed by 2022, the Riachuelo system will treat 2,332,800 cubic metres of wastewater a day. Given its social and environmental importance, the $1.2-billion cost of the system is supported financially by the World Bank.

With the contract awarded, performed for Agua y Saneamientos Argentinos S.A. (Aysa), the Salini Impregilo Group, which is already involved in Lot 3 of the Riachuelo system, confirms its strategic role in the development of an important project to fight pollution in the Argentinian capital.
