Argentina's President Cristina Fernández has kicked off a new phase of construction work on a tunnel that will channel water to the Juan Manuel de Rosas potable water treatment plant in the Tigre district of capital Buenos Aires.
A tunnel-boring machine (TBM) is currently excavating a tunnel that will connect a water intake on the Luján river with the Juan Manuel de Rosas plant. Another TBM is working to connect the Luján river with the Paraná de las Palmas plant, El Comercio Online reported.
The tunnel measures 15km and will have capacity to transport 400m3/d.
The work is part of the Juan Manuel de Rosas potable water treatment plant project, which will supply the resource for up to 3mn people, according to the national planning ministry. The government is investing 2.8bn pesos (US$666mn) in the project.
Work is being carried out by state-controlled water and sewage utility AySA.
