With respect to the port Project, due to the shortage of water in the region, priority has been given to the use of groundwater over surface water, in order to avoid competition with other
EFFICIENT WATER USE
In line with the second strategy from its water management policy, DrummondLtd. has programs to recover water in different processes in its mining operations. At the mines, the water that is recovered is from the coal washing process.
surface water uses existing in the region, particularly including human consumption. For this reason, Drummond in 2015 only used 11.3% of the flow rate granted in concession of surface water.
G4-EN10
Although currently there are no meters that reveal the total amount of water recycled in these processes, it is estimated that 50% of the water required for the coal washing plant is reused in the same process, as shown in the following table:
