Lagares WWTP receives the Segovia Aqueduct Award for Public Works and the Environment

The Vigo Sanitation action, integrated in the Lagares WWTP and in whose construction OHL participated, received the Segovia Aqueduct Award for Public Works and the Environment, granted by the Roads Foundation and the Association of Civil Engineers, in the ninth edition of these awards.

This recognition, which is national in nature and has been granted every four years since its foundation in 1998, highlights the positive impact of the infrastructure, as it has solved the environmental problems of the area in which the old treatment plant, which has been in operation since 1997, had been previously operated.

The new Lagares WWTP, designed entirely by OHL and GS Inima technicians, is a pioneer in incorporating a thermal hydrolysis system for the sludge, which increases the performance of biogas energy recovery. Furthermore, its design makes it the largest plant in Spain for biological treatment with biofiltration technology and one of the largest in Europe.

Among its most noteworthy technical characteristics is the system for the treatment of odors – the plant has a biological deodorization system called biotrickling. The plant has also helped to improve the microbiological quality of the swimming areas – with the recovery of the blue flag for Samil Beach and the creation of a reference infrastructure within the sanitation engineering sector. In addition, a covered structure prevents noise and odor pollution and facilitates its integration into the urban environs.

This recognition joins the award for the best engineering work in the XI San Telmo Awards 2019, granted by the Galician Association of Civil Engineers, for its innovative character; the Galician Architecture and Rehabilitation Award 2018, granted by the Regional Government of Galicia; the Gran de Área Award 2017, granted by the Galician Association of Architects, and the international WEX Global Awards 2016 in the category Water&Energy Awards, granted by the English company Water and Energy Exchange.
