OUR PRIORITY
AREAS

WATER

Grupo México is committed to being strategically mindful of the water resources at our operations, for the wellbeing of our communities and for biodiversity conservation.

Our water care includes activities throughout the lifecycle of our projects and productive chain, how we use this resource and the quality of the water we return to the environment.

Our water management is built on 4 pillars:
Protect the quality of the water we return to the environment
Improve efficiency in our water usage
Collaborate with other stakeholders in the management of the watersheds where we work
Manage the risks associated with water management at our operations

For more information, see Management Approach

OUR COMMITMENTS:

  • Protect the quality and availability of water in the watersheds where we operate.
  • Invest in infrastructure and technology to reduce our usage of freshwater and improve our water efficiency.
  • Collaborate with other stakehokders in the management of the watersheds where we work.
  • Comply with all water management and usage-related regulations, as well as monitoring and reporting.
  • Manage the risks associated with water management at our operations, systematically monitoring and testing the availability and quality of the resource in the watersheds and also the ground and/or surface water sources.

MANAGEMENT APPROACH
Mining
Organizational Management

Our water management focuses on four pillars:

Protect the quality of the water we return to the environment.
  • Accredited labs systematically monitor and test the quality of the water at all our operations.
  • We have installed water treatment systems for both our operations and for the neighborhoods where our employees live.
  • Proper mine waste management to protect the quality of the water in the watersheds where we operate.
  • We manage risks efficiently and proactively to prevent incidents and the release of leaching solutions that could affect natural waterbodies.
Improve efficiency in our water usage.
  • We optimize our water usage thanks to high-tech devices and innovative systems, reducing our water consumption and increasing recirculation, prioritizing the productive processes that consume the most water. One example is the Toquepala expansion in Peru, where we doubled production without increasing the amount of freshwater used.
  • We guarantee continuity in the availability of water in the aquifers and ground and/or surface water sources on which our operations depend.
Collaborate with other stakeholders in the management of the watersheds where we work.
  • We protect the availability and quality of the water in the places where we operate, collaborating with the community on the efficient use of this resource.
  • We seek solutions to water-related issues to achieve results that are socially equitable, environmentally sustainable, economically efficient and politically viable.
  • We support conducting studies and technical assistance, investments in irrigation infrastructure and projects to optimize the potential of the watersheds we share.
Manage the risks associated with water management at our operations.
  • Most of our tailings dams are constructed to the downstream method, using loan materials, considering return periods of 10,000 years, overflow canals, rainwater diversions and contingency systems.
  • We develop water harvesting programs to reduce soil erosion and evapotranspiration and improve water capturing.
