A partir del 12 de diciembre de 2025, México estrenará un nuevo marco jurídico en materia de aguas que replantea por completo la gestión del recurso hídrico. La nueva Ley General de Aguas y la renovada Ley de Aguas Nacionales introducen cambios de alto impacto para todos los usuarios — industria, agricultura y sector doméstico— fortaleciendo el derecho humano al agua y saneamiento, centralizando facultades en CONAGUA y actualizando el régimen de concesiones, permisos y sanciones.

Este nuevo esquema exige a las empresas actuar proactivamente, revisar su situación actual y ajustar procesos para mantenerse en cumplimiento, enfrentar retos y aprovechar oportunidades como la reasignación de volúmenes, la necesidad de tramitar nuevas autorizaciones, navegar por nuevos criterios para obtener prórrogas y beneficios vinculados a la responsabilidad hídrica. Además, el régimen transitorio establece una entrada en vigor inmediata, mientras que los mecanismos de reasignación serán aplicables 180 días después, y en los próximos meses se espera que se emitan nuevos reglamentos y una NOM de medición.

Changing Waters: Navigating Mexico’s New Water Legislation

As of December 12th, 2025, Mexico will implement a new water regulatory framework that fundamentally restructures the management of national water resources. The new General Water Law (Ley General de Aguas) and the updated National Waters Law (Ley de Aguas Nacionales) introduce significant changes for all users—including industry, agriculture, and the domestic sector strengthening the human right to water and sanitation, centralizing key powers within CONAGUA, and updating the regime governing concessions, permits and sanctions.

This new framework requires companies to act proactively, assess their current situation and adjust internal processes to remain compliant and leverage emerging opportunities, such as the reallocation of water volumes, new authorization requirements, navigate through the new criteria for extensions, and  benefits  linked  to  water  stewardship.  Additionally,  the transitional provisions establish immediate entry into force, while the reassignment mechanisms will become applicable 180 days later. In the following months, new regulations and a technical standard on water-measurement systems (NOM) are expected be issued.

The attached document includes a detailed analysis of:

• Key reforms to the concession regime and reallocation of water rights.
• New obligations and prohibitions.
• Updates to sanctions and related criminal-risk exposure.
• Practical implications, implementation timelines, and upcoming regulations.
• Recommendations to prepare and adapt from now on.
