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


  • 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.

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.

Roles & Responsibilities

The organizational supervision of water management is structured as follows:


Strategy and compliance
Operational supervision
Responsible coexistence
  • Executive Leadership /

    Board of Directors

    Evaluates performance and progress on the corporate goals, targets and indicators, and investment projects related to water. Identifies areas of opportunity, needs, risks and potential synergies.

    • Audit


      Mechanism developed for the Board to monitor and promptly follow up on the management of our environmental, social and governance-related risks.

      • Sustainable Development Committee

        Reviews the strategy, performance and principal improvement projects. Submits recommendations to the Board of Directors.

        • Sustainable Development Department

          Leads the design and implementation of projects, initiatives and actions, in close collaboration with the other divisions and relevant areas of the company.

          • Community Development Department

            Participates in the collaboration with other stakeholders in the management of the watersheds to manage and develop water resources in a balanced and sustainable manner.

        • Operations


          Participates in the Sustainable Development Committee; responsible for the efficient use of water and for ensuring our discharges are below regulatory levels.

          • Business


            Each unit or operation is responsible for its own water management, which is supervised by the Head of each operation.

        • Engineering and

          Construction Department

          Develops systems to manage water resources safely and efficiently at all our operations.

        • Water Management


          Ensures compliance is met with applicable regulations; monitors the efficient management and ongoing improvement of our processes.


Our water management ensures compliance with the regulatory framework regarding extraction and discharge in all countries where we have operations, and includes:

Responsible management
Continuous monitoring
Risk mitigation
Continuous improvement
Prompt payment of water costs.
Responsible management
Proper management of our ground and/or surface water withdrawal and usage licenses, rights and permits.
Continuous monitoring
Quality monitoring measures for wastewaters and, where necessary, implementation of treatment systems.
Risk mitigation
Monitoring of the water systems at our operations in terms of water availability, volume and quality to understand the performance of these systems and to identify and mitigate risks.
Continuous improvement
Incorporate international good practices, like the International Council on Mining and Metals (ICMM) Water Stewardship Framework.
The minimum standards for water returned to the environment are set out in the federal regulations of each country where we operate:
  • Official Mexican Standard NOM-001-SEMARNAT-1996-001
  • Environmental Quality Standards for water and the Maximum Permissible Limits, established in Law No. 28611 – General Environmental Law
  • Our operations have been working with a Canadian Association for Laboratory Accreditation (CALA) accredited Environmental Lab since 2001
  • Section 304 (A) of the Clean Water Act
  • EPA 40 CFR Part 440
  • EPA 40 CFR Part 440.100
  • Aquifer Protection Permit – APP (AAC-R18-9-Article 2)
