The contract includes the design and construction of a seawater desalination plant in Puerto Patache in Collahuasi, located 70 kilometres south of the city of Iquique in the Region of Tarapacá (Chile).

The Puerto de Patache plant will have an initial capacity of 1,050 litres/second. The work includes the construction of marine structures and a pre-treatment system and the development of reverse osmosis and post-treatment technologies to ensure the availability of water resources whose quality responds and adjusts to the different operating conditions of the mining sector.

 

The project, awarded by Compañía minera Doña Inés de Collahuasi (CMDIC), one of the main Chilean mining companies, is part of the "Infrastructure Development and Productive Capacity Improvement" plan for CMDIC's operations in the Tarapacá region, and also contemplates the operation and maintenance of the plant by ACCIONA for two years, extendable for another three years.

The construction of this new seawater desalination plant consolidates ACCIONA as one of the benchmark companies in the water treatment activity for mining operations in Chile. One of the company's most outstanding projects in this field was ACCIONA's first desalination plant that provides water for mining use through reverse osmosis technology, in Copiapó (Atacama region).
