"It is one of the country’s most important infrastructure projects from the past 50 years" said President of Argentina, Cristina Fernández de Kirchner. She was talking about the construction of the "Juan Manuel de Rosas" water treatment plant in Tigre on the northern edge of Buenos Aires’ metropolitan area. The plant and an extensive pipeline network will supply around three million people with 1.2 million cubic meters of water per day.

Two Herrenknecht EPB Shields have been drilling the nearly 15 kilometer long tunnel that drains the water from the Paraná River and feeds it into the processing plant. The two machines set to work at depths of down to 20 meters from a common starting shaft in April and October 2011. The Earth Pressure Balance Shield "Liliana" is driving in the direction of the treatment plant, while "Cristina " is making her way towards the river. The excavated tunnel is lined with segments that are produced in a factory that was planned and equipped with the complete mould system by Herrenknecht Formwork. Then, in August and September 2013, the big success for the teams and the machines: breakthrough for the two Herrenknecht EPB Shields after best performances of up to 26.6 meters per day and 28.8. meters per week.
