ACCIONA has just completed construction of the tunnel for the future Line 6-Orange of the São Paulo metro. Last Sunday, in one of the most important milestones of the project, the South TBM, called Maria Leopoldina, arrived at the São Joaquim station, connecting the 15 future stations of the new line.

Since leaving the Tietê ventilation and safety shaft in December 2021, the TBM has traveled nearly 8.9 kilometers, achieving daily averages of more than 25 meters and even setting an operational record last October when it dug 41.3 meters in just 24 hours.

The project’s two TBMs have excavated more than 60 meters of tunnel per day, requiring another logistical feat of 840 truck trips to transport more than 6,500 cubic meters of excavated material.

With Sunday's milestone, ACCIONA has built more than 14 kilometers of tunnel with the South and North TBMs. Work is currently underway on the 15 stations, the Morro Grande Yard and the 18 ventilation and safety shafts. In total, 10 stations have already been excavated and 2.4 kilometers of tunnels have been constructed using the conventional method.

With a committed investment of more than 19 billion reais (€3.106 billion) Line 6 is the largest infrastructure project underway in Latin America. The project has already benefited more than one million people, including professionals and members of the community, through various social initiatives carried out during the construction period. It is also promoting the role of women in the infrastructure sector, with more than 900 women already employed.

The line will connect Brasilândia, in the north of São Paulo, with São Joaquim station in the city center and will carry more than 630,000 passengers per day. The journey time on this route, which currently takes about one and a half hours by bus, will be reduced to just 23 minutes. The line between Brasilândia and Perdizes will be completed by the end of 2026. The section between Perdizes and São Joaquim will be operational in 2027.

KEY MARKET

ACCIONA has been present in Brazil for more than 25 years. During this time, it has developed several emblematic infrastructures, such as Terminal 2 of the Port of Açu (State of Rio de Janeiro) and the transformation of the historic Júlio Prestes railway station in São Paulo into a world-class concert hall.

In terms of experience in sanitation and water treatment projects, the company has extensive experience in the country through projects such as the sanitation system, including networks, collectors, pumping stations and ETE (wastewater treatment plant) of the Alcântara basin, in São Gonçalo, the second largest city in the State of Rio de Janeiro; the design, construction and operation support for the Santa Cruz do Capibaribe wastewater treatment system, in the Pernambuco region (in the northeast of the country).

Recently, in January, ACCIONA was awarded the tender by Sanepar (Paraná Sanitation Company) for the concession of sewerage services in 48 municipalities in the western and central-eastern micro-regions of the State of Paraná.

The company also installed, operated and maintained the energy cogeneration system at the Arrudas wastewater treatment plant in the State of Minas Gerais.
