Water treatment plant operation

Veolia

Operation and maintenance contract for the desalination plant at Cerro Lindo mine owned by Milpo.

This three-year contract covers water intake and production of desalinated water by reverse osmosis. Milpo's desalination plant has an industrial process water production capacity of 48 l/s to meet Cerro Lindo mine needs. Starting in 2016, the output will be raised to 60 l/s, a 20% improvement in the plant’s performance from its current level.
