Saltwater propulsion systems
The operation
Non-desalinated saltwater supply
Aguas Esperanza owns, operates, and maintains the two Seawater Pumping Systems (SIAM) that supply Antofagasta Minerals’ operations from the Michilla area in the Antofagasta Region.
SIAM I
The first system, existing since 2010, was acquired by Aguas Esperanza in early 2024 and has been operated by our company since then. It supplies non-desalinated saltwater to 100% of the Centinela and Antucoya mining operations.
SIAM II
This second system was built by Aguas Esperanza during the first two years of the contract
starting in 2024, and today, as of March 2026, it adds 56,000 m³/day to the transport capacity.
Combined with the 100,000 m³/day already operated by SIAM I, it will supply the water
required for the expansion of the operation with its Nueva Centinela project.
