BHP Cerro Colorado mining site (CMCC), is an open-pit copper mine, which had a dewatering system that worked with submersible pumps, which drive the water to two ponds, from where through conventional pumps, water trucks were loaded for dust control of internal roads of the mine. The surplus water was transported to the water reservoir of the plant.

After several studies, CMCC decided to install a continuous pumping system with multistage centrifugal pumps to the reservoir.

Pares&Alvarez developed advanced basic engineering in the disciplines of process, civil/structural, mechanical/piping, electricity, and instrumentation and control for the design of the project, which considered the implementation of a 50 lps water extraction system with submersible pumps continuously from shallow wells at points near the loading fronts. The water extracted from the bottom of the mine is stored in pools or small ponds at a slightly higher level, and then pumped with multistage centrifugal pumps to the reservoir, which also have a filling system of water trucks for road dust control.

The power supply for the equipment will be through generator sets or power line from fixed substation transformers.
