This is one of the most relevant projects for the Atacama region that guarantees the supply of quality drinking water for 70% of the population.

GS Inima has designed and built this work together with Claro Vicuña Valenzuela (CVV) through the consortium Inima-CVV Copiapó.

The work that was awarded in 2017 to the Consortium Inima-CVV Copiapó, is one of the most relevant projects for the Atacama region, not only because it is the largest projected investment in the area, but also because it guarantees the supply of drinking water in a sector that no longer has natural aquifers for self-supply.

The project, which benefits more than 210.000 inhabitants of the communes of Chañaral, Caldera, Copiapó and Tierra Amarilla, has involved an investment of close to 100 million dollars and the generation of more than 500 direct jobs during its execution.

From the social, technological and environmental point of view, Inima-CVV incorporated the highest standards that generate a series of advantages:

• The desalination plant has a guaranteed electricity consumption of less than 2,8 kWh per cubic meter, which makes it one of the most efficient plants worldwide.

• The design contemplates the construction in three stages, which allows a final maximum capacity of 1.200 liters per second (l/s) of potable water.

• The marine works were carried out using microtunneling technology, minimizing the environmental impact.

Additionally, the project is powered by a clean, 100% renewable, wind and solar energy source.


“What we are seeing here is a milestone that is going to mark a fundamental change. This is a region that was under the permanent risk of running out of water and today it is the only region in Chile that has its water guaranteed for the next 40 years. Not only is it the most modern desalination plant that we have in our country, it has also incorporated many technological advances in energy efficiency and is also very friendly to the environment”. Sebastián Piñera, President of Chile.

The Atacama Desalination Plant is a country project, a priority in public policy, and which has been promoted and supported by the government of Michelle Bachelet, since its approval in 2015, as well as by President Sebastián Piñera and by the different regional and local authorities. .

“Successfully completing one of the largest state works in the Atacama Region, guaranteeing the supply of drinking water in an area affected by water scarcity, reaffirms our commitment in the water treatment sector in Chile. At the plant we have considered various technological and environmental innovations, which make this project a success story and a benchmark in the sector”Diego de Vera, Business Development Director of GS Inima.

GS Inima will continue with its commitment to the region, operating and maintaining the Atacama Desalination Plant, guaranteeing the continuity of good environmental and social results. This contract also consolidates the presence of GS Inima in Chile, as it is the fourth desalination project in which it adds value throughout the cycle: design, construction, financing, operation and maintenance.
