U.S. and Mexico Sign Acta 333 to Resolve Tijuana Wastewater Crisis

The pact imposes firm timelines with dedicated financing plus binational oversight to deliver a durable fix.

Overview

  • Acta 333 creates a three‑month binational working group to evaluate a submarine outfall and the expansion of the San Antonio de los Buenos plant from 18.26 MGD to 43.37 MGD.
  • A sedimentation basin at Smuggler’s Gulch is slated for completion before the 2026–2027 rainy season to curb cross‑border pollution.
  • The agreement schedules construction of the Tecolote–La Gloria wastewater plant with 3 MGD capacity by December 2028.
  • NADBank will establish an operations and maintenance account with recommendations due in 12 months, structured to avoid additional U.S. taxpayer funding.
  • Implementation begins immediately with joint monitoring, after the accord was signed in Tijuana under the July MOU’s year‑end deadline and entered into force.
