After a two-year construction period, the first clean water flowed from the Tocopilla Desalination plant in May 2019. PENETRON ADMIX was specified over a competitive crystalline admixture as a superior performing waterproofing solution for the concrete water tanks.

Part of the Empresas Públicas de Medellín (EPM), a Colombian conglomerate with holdings in the water and sanitation industry, the Aguas de Antofagasta (ADASA) is a Latin American leader in water desalination.

In operation since 2003, ADASA currently provides clean water to 546,000 inhabitants in seven Chilean towns. In total, the company treats 2.11 m3 (560 gallons) of water per second, with about 30% originating from seawater.

For this purpose, it has desalination plants in Taltal and Antofagasta, the latter considered the largest water desalination plant in Latin America, with a production of 600 liters (160 gallons) per second.
