Why it matters

The sewage crisis represents a significant public health and environmental emergency for South County residents. The sheer volume of sewage crossing the border—over 100 billion gallons since 2018—demonstrates a critical failure in transboundary infrastructure, leading to daily beach closures and contaminated water.

This issue is not isolated to San Diego County. It is a complex, transboundary problem shaped by the explosive growth of Tijuana and the infrastructure decisions made on both sides of the border. The crisis highlights the need for coordinated action and funding from both the United States and Mexico to repair broken pipelines and expand wastewater treatment capacity.
