We recognize the importance of water, and we value it as a shared resource. We optimize our water use and avoid discharges by using closed circuits. In most of our facilities we conduct direct and indirect metering and strictly control consumption.

We use water primarily to process minerals, in chemical reactions, the cooling of industrial equipment, control and prevention of emissions, and for drinking and washing by our personnel.

Our operations do not significantly affect any water source. The corresponding regulations require a permit or concession from the federal or national water authorities, depending on the availability of the resource. In the case of pit water, its use also has no impact on water sources, because given the conditions and depths from which it is extracted, it is not connected directly to underground aquifers or surface runoff, which are the supply sources exploited by other users of this resource.

In 2020, the total amount of water extracted from natural sources—springs, ground water, municipal water systems and pit water—for all our operations totaled 8.17 million cubic meters. This was complemented with 5.15 million cubic meters of municipal wastewater, purified in our treatment plants. Both types of water are used in productive processes and sanitary services. The rest of it is recirculated water from our facilities, and is equivalent to the consumption of 14.83 million cubic meters. The reduction in the amount of recirculated water compared to last year (33.8 million cubic meters) was due to the conclusion of operations at Milpillas, Madero and Bismark.

The volume of surface water, ground water, pit water, treated water or water we consume from outside sources is determined by direct metering; the volume of recirculated water is obtained by an estimate of pumping capacity and operating time.
