G.O.C. participates in 200 million euros project for WWTP in Vigo

The new WWTP of Lagares river in Vigo (Spain) was inaugurated on 4 April 2018, becoming the largest hydraulic work in Galicia and one of the largest in Spain. Since its inception, G.O.C. has actively participated in this project, which has a construction value of 208.7 million euro.

The new facility includes the primary, secondary and tertiary treatment of the water line, as well as a sludge treatment line that reduces the waste generation and contributes to an improvement in the overall energy efficiency.

The design of the facility buildings seeks their integration within the environment surrounding the treatment plant by using neutral materials and colours. In addition, the buildings have ventilation and deodorization systems necessary to minimize the odoriferous impact.

The project included the construction of a submarine outfall, which aims to increase the effluent dilution and to transfer treated wastewater to an environmentally suitable place. Additionally, the electrical system has been enhanced with the construction of a new distribution substation.

In addition to its social and environmental value, the WWTP has an architectural relevance endorsed by several awards:
