Sacyr Water, selected to develop Chile’s first ever desalination plant under a P3 model

November 17, 2025

  • The desalination project, located in Coquimbo, foresees an investment of close to 318 million dollars and will benefit more than 540,000 people.
  • The plant will have an initial production capacity of 800 liters per second, with the possibility of expanding to 1,200 liters per second.

Sacyr Water has been selected for the concession award for the design, financing, construction, and operation of the new desalination plant in Coquimbo (Chile), in the north of the country.

It is the first desalination plant for human consumption in the Coquimbo region, a project promoted by the General Directorate of Concessions of the Ministry of Public Works (MOP) to guarantee water supply in one of the areas most affected by drought in the country.

Investment and expansion

This project is the first desalination project awarded under a P3 scheme in Chile and foresees an estimated investment of $318 million. The desalination plant will have an initial capacity of 800 liters per second (l/s), with the possibility of expansion to 1,200 l/s, and will directly benefit more than 540,000 people in the communes of La Serena, Coquimbo, and Ovalle.

The project also includes the construction of a desalinated water pipeline of approximately 60 kilometers, pumping stations and a regulation pond, which will allow an efficient and safe distribution of water resources.

Sacyr in Chile

Sacyr has been present in Chile since 1996 and has developed projects in its three key areas: Concessions, Engineering and Infrastructure, and Water. Currently, it operates 5 airports, 11 concessioned routes, 7 hospitals in different stages of development and sanitary plants that cover the complete water cycle.

The construction of a pioneering and sustainable water reuse and treatment plant in Antofagasta has recently begun, marking a significant initiative in Latin America.

With activities in 14 of the country’s 16 regions, Sacyr generates more than 4,100 direct jobs, reaffirming its commitment to sustainable development and the well-being of communities.
