Desalination is not the only answer to Chile’s water problems – Chile

Chile produces nearly a quarter of the world’s copper supply, with the majority of production coming from the northern provinces (Exhibit 1). That same region is one of the driest places on the planet.

During 2019, Chile experienced its worst drought in decades, with the government having to supply fresh water to almost 400,000 residents.

Annually, the mining industry consumes enough water to provide for 75 percent of the needs of Chile’s population.


Yokogawa Wins a Control System Order for the Provisur Seawater Desalination Project in Peru – Peru – South America

Yokogawa Electric Corporation announces that the Peru branch of Yokogawa América do Sul (a Yokogawa Electric Corporation subsidiary) has received a control system order from Técnicas de Desalinización de Aguas, S.A. (Tedagua) for a water desalination plant and associated facilities that it is building for Servicio de Agua Potable y Alcantarillado de Lima S.A. (SEDAPAL) in the Santa Maria district of Lima, the capital of Peru.

With the Provisur seawater desalination project, Peru’s first reverse osmosis desalination plant is being constructed to supply 35,000 m3 of potable water per day to the 100,000 residents of the Santa Maria district.

Water distribution and sewer pipelines (total length: 260 km), a sewage treatment plant (daily capacity: 15,500 m3), and an undersea pipeline (780 m) for the discharge of treated water are also being built.

Part of the treated water will be used for watering plants in the local area. Expectations are high for this project because Lima and other coastal areas in Peru have a desert climate that gets very little rain throughout the year.
