Water management is a top strategic priority for the Company. To minimize water withdrawal, the group’s units invest in:
- sewage-treatment projects so that effluents can be industrially reused;
- rain-water impoundment for machine and equipment cooling;
- campaigns on the rational use of water for its employees and service providers.
One example of this commitment is the high rate of freshwater recirculation presented by ArcelorMittal Brasil : which, in 2013, peaked at 98.28%
The strategy to reach that goal involves maximizing the use and internal recirculation of water.

Evolution of water consumption (in million m3)
ArcelorMittal Brasil’s manufacturing processes do not affect significantly any water source. Notably, licenses are granted based on the capacity of the water bodies (surface or underground).
