In July 2026 Deputy Ricardo Monreal Ávila presented his book on the General Water Law that had taken effect on 11 December 2025, framing water as a public good and a constitutional right. Six months after implementation, he noted voluntary returns of unused concession rights and a state‑led reclamation process, while detailed regulations were pending and the 2027 budget promised higher water‑related spending. Later that month, Mexico’s congress formally approved the law, emphasizing its human‑right basis but acknowledging the lack of detailed rules needed by investors, which could delay billions of pesos in capital projects.

On 28 July 2026 the Chamber of Deputies’ Water Resources, Potable Water and Sanitation Committee rejected a PRI‑backed amendment that sought to expand water‑rights transmission and allow provisional third‑party use of concessioned water. The committee argued the amendment duplicated provisions already covered by the recent hydraulic reforms. In parallel, a coalition of civil‑society groups held a virtual workshop to draft a normative chapter on water rights for Indigenous peoples and Afro‑Mexican communities, aiming to shape the forthcoming General Law on Indigenous and Afro‑Mexican Rights and ensure autonomous management of water resources for these groups.
