How could the county's proposed infrastructure fixes affect the International Boundary and Water Commission?
County's plan to build new treatment plant near border Paloma Aguirre's recovery plan includes a county initiative to construct a treatment plant near the U.S.-Mexico border to capture and clean raw sewage flowing through the Tijuana River. This new infrastructure is proposed to be separate from the existing South Bay treatment plant, which is operated by the International Boundary and Water Commission. Because the county's plan aims to address pollution flows that currently cross the border untreated, the implementation of this new system would require coordination and agreement with the IBWC regarding the management of the river system.

How it reaches International Boundary and Water Commission
-
San Diego County is moving forward with a plan to construct a treatment plant near the U.S.-Mexico border to capture and clean raw sewage flowing through the Tijuana River. Separately, San Diego County Measure B proposes a half cent sales tax increase, which would raise the county sales tax from 7.75% to 8.25%.

Everything about San Diego County -
The existing South Bay International Wastewater Treatment Plant, operated by the U.S. section of the International Boundary and Water Commission, does not treat polluted flows that enter the Tijuana River itself and cross the border untreated. Therefore, the county's new capture and cleanup initiative would require coordination with the IBWC regarding the management of the river system.

- Between 2018 and 2026, more than 200 billion gallons of polluted water crossed into the U.S. through the Tijuana River.sandiegouniontribune.com

Why it matters
The Tijuana River sewage crisis poses a severe public health threat, with researchers estimating water pollution causes roughly 34,000 illnesses annually in Imperial Beach alone. The county's proposed initiative represents a major shift in how the pollution is managed, moving toward a county-led solution to reduce dependence on federal or Mexican government action.
This effort directly challenges the current operational framework of the International Boundary and Water Commission. While the IBWC manages the existing treatment plant, the county's plan seeks to establish a separate, border-adjacent capture and cleanup system. The success of this new infrastructure depends heavily on the ability of the county to coordinate its plans with the international body that governs the river system.
