The desalination sector in Latin America is undergoing significant expansion with more than $20 billion committed to projects across the region, according to industry data. This investment momentum reflects accelerating deployment of desalination technology to address water scarcity challenges, particularly in mining-intensive nations.
Chile represents the core of regional investment, with over $18 billion committed to desalination projects largely driven by copper mining demand. The country currently operates 11 desalination plants with a combined capacity of 6,472 liters per second, primarily serving industrial users. Water demand from Chile's copper mining sector has increased significantly, while seawater now represents more than 30% of total mining water use, indicating a substantial transformation in the industry's water mix.
Globally, more than 17,000 desalination plants produce around 107 million cubic meters per day, supplying water to over 300 million people. Latin America's rapid growth in this sector is evidenced by more than 25 desalination projects currently under development, led by Chile and Peru. Peru is actively promoting six new seawater desalination plants to expand access to drinking water, demonstrating a public-sector push to address water security concerns.
The regional developments will be highlighted at the 8th International Congress "Desalination Latin America 2026" scheduled for June 17-18, 2026, in Santiago, Chile. The event, organized by Vostock Capital with official support from Chile's Ministry of Mining, will bring together industry leaders to discuss the sector's future. More information about the congress is available through the official website.
This investment surge matters because it represents a strategic response to water scarcity challenges that affect both industrial operations and public water supplies. As climate change intensifies drought conditions in many Latin American regions, desalination offers a technological solution to secure water resources. The mining sector's substantial investment in desalination infrastructure could serve as a model for other water-intensive industries facing similar challenges.
The implications extend beyond industrial applications, as demonstrated by Peru's initiative to expand drinking water access through desalination. This dual approach addressing both industrial and municipal needs suggests desalination could play a crucial role in regional water security strategies. With Chile's copper mining sector increasingly dependent on desalinated seawater, the technology's reliability and scalability are being tested at an unprecedented scale in Latin America.
The concentration of investment in Chile highlights how resource extraction industries can drive technological adoption that may eventually benefit broader populations. As desalination costs continue to decrease and efficiency improves, the projects currently focused on mining operations could pave the way for more widespread municipal applications throughout water-stressed regions of Latin America.
