Overview
- President Claudia Sheinbaum said Mexico will deliver under the 1944 Water Treaty only the volume physically available, despite President Donald Trump’s tariff threat.
- She attributed recent delivery shortfalls to a five‑year drought and noted the treaty’s provision to make up water in subsequent years depending on 2025 rainfall.
- Sheinbaum said the United States needs to expand a treatment plant in San Diego, and Mexico will build new collectors and enlarge its own plant starting next year.
- She cited two sanitation accords for the Tijuana River: a prior-government deal that produced a functioning plant built by military engineers and a separate understanding signed by Alicia Bárcena and U.S. EPA chief Lee Zeldin.
- Binational technical teams remain at the table to finalize an agreement and avoid a tariff dispute, and Sheinbaum suggested Trump’s contamination claims stem from incomplete information.
