ACCIONA has been awarded two new contracts in Portugal for the tertiary treatment of water from the Vilamoura wastewater treatment plant (WWTP) in the Algarve and the Carvalhal WWTP in Mafra, a Portuguese town in the Lisbon District.
The tertiary treatment of the Vilamoura WWTP, awarded by Águas do Algarve, together with the local company Tecnorém, will produce high-quality water from reclaimed wastewater, which will then be used for the irrigation of golf courses. The treatment will be carried out using ultrafiltration technology, with a capacity of 1,000 m³/h. The plant is expected to be operational by mid-2026.
On the other hand, the contract for the Vilamoura WWTP has been awarded by Águas do Tejo Atlântico. The WWTP will use activated sludge technology with capacity to treat 356 m³/h. Thanks to this contract, the wastewater treatment will reach the town of Carvalhal for the first time and will contribute to implementing the appropriate environmental measures to avoid polluting the Lizandro River and, consequently, the touristic beach of Foz do Lizandro.
The two contracts total €6 million and have a combined treatment capacity of 1,356 m³/h.
Vast experience
ACCIONA has participated in the construction of more than 70 infrastructure projects in Portugal, one of its first international markets. These include the Oriente Station in Lisbon; the Infante Don Henrique Bridge, which links Vila Nova de Gaia and Oporto; the Olhão marina, in the city's riverside area, which is part of the Ria Formosa Natural Park, one of the Algarve's major natural resources; and the Alqueva dam on the Guadiana River in the Alentejo region.
In the water sector, the company has built more than 30 wastewater and drinking water treatment plants. The Alcantarilha water purification plant stands out, which provides drinking water in the Algarve area, with a maximum production capacity of around 260,000 m³/day, as well as the Sul-Ilhavo WWTP in Aveiro, with a capacity of almost 39,300 m³/day.
Other noteworthy projects are the Faro-Olhão WWTP, two kilometers east of the city of Faro, with capacity of more than 28,000 m³/day; the Companheira WWTP in Portimão, Algarve, with capacity to treat more than 32,000 m³/day; and the Ermidas do Sado WWTP, which will serve 4,100 residents in the district of Setúbal, in the central-southern region of the country.
