How much water would be required for coal washing?
It is estimated that 330 to 490 cubic metres of water will be used per day for coal washing. This is equivalent to the amount of water a medium to large hotel uses in an average day.
How will the environment be protected from the coal washing process?
Almost all the water used in the coal washing process (about 99%) is expected to be recycled. Any water released will meet or be better than government water quality standards. A comprehensive water management plan will be implemented to safely and efficiently manage all water requirements.
