Water management

Mining requires water. However, water consumption in the mining sector varies depending on the extracted resource, the extraction and processing methods, the location of a mine and even the mode of transportation. Furthermore, inadequate and inefficient water management can affect the quality of surface and groundwater, and exacerbate existing water stress.

Thus, the mining sector faces two challenges: preventing the pollution of water resources and reducing its consumption by increasing water efficiency.

Protecting water quality

When managing water resources, looking at the whole water catchment enables more complete understanding of water uses and users, hydrology, and ecological dynamics. The ICMM offers a Practical Guide to Catchment-Based Water Management which helps companies identify water catchment risks of their operations.
