Tunnel Collapse in Wilmington Traps 30 Workers Underground

Los Angeles, CA: July 9, 2025 – Late Night Incident A tunnel collapse in Wilmington, California, late Wednesday night trapped more than 30 workers underground. The incident occurred at the Los Angeles Effluent Outfall Tunnel project, part of the $630 million Clearwater Project overseen by the Los Angeles County Sanitation District.

According to the Los Angeles Fire Department (LAFD), 31 workers were safely rescued without reports of serious physical injuries. The collapse took place roughly 450 feet below ground.

Four additional workers voluntarily descended to assist their colleagues immediately after the collapse. Thanks to highly trained confined-space rescue teams, all individuals were evacuated within about an hour.

Workers’ Rights May Have Been Violated

Even in the absence of visible physical injuries, every worker has the right to a safe work environment under California Labor Code §§ 6400–6403. In cases like this, multiple labor rights concerns could be at stake, including:

At Ayuda California, we commend the swift action of emergency responders. However, no worker should ever be placed in life-threatening conditions. Safety is not a privilege—it is a legal right, regardless of immigration status or type of employment.
