At a global level, AHMSA is one of the steelworks with the lowest water consumption in its processes, and it is recognized for its high levels of regeneration.

Our efforts in the area of water saving and efficient use focus on:

  • Reduction of extraction of raw water
  • Greater usage of treated water.

Important actions:

  • Since 1992, AHMSA has been implementing a program for promoting awareness and providing training regarding water usage for its employees in all of its facilities.
  • The company’s modernization process included environmental improvement and equipment for greater efficiency in the use of water as some of its main requirements.
  • In 1995, a sewage water treatment plant was constructed for the city of Monclova, Coahuila, with a capacity of 450 liters per second, which is reused by AHMSA.
  • In 2006, the capacity of the plant increased to 650 liters per second. AHMSA currently uses 580 liters per second of the water treated at the plant in its industrial processes.
  • In 1995, 30 million dollars were invested in a hydrochloric acid regenerating plant, in order to eliminate the discharge of acid water into local streams.
  • As a result of studies done in 2008 and 2009, investments were made in projects to use industrial water in the processes, thus reducing by up to 156 liters per second, the use of raw water.
  • Currently, only 2.9 m3 liters of water are used per ton of steel produced, one of the lowest rates worldwide.
  • The MICARE Unit designed and applied a system for reinjecting the water drawn from mines back into the water table. The system is endorsed by the Mexican Institute for Water Technology (IMTA) and the South West Research Institute, of Texas, USA, and is currently a national model for reinjection to aquifers.
  • Through the actions geared toward a more efficient exploitation, AHMSA and its companies has avoided the extraction of hundreds of thousands of liters of water from the regional aquifers.
