Investigation Summary

At 11:45 a.m. on February 23, 2023, an employee working for a city water department was repairing a leaking 12-inch PVC waterline main valve. The valve was located in a utility vault approximately 5 feet deep. The employee turned off the water to the west of the valve by opening multiple fire hydrants. He and a coworker then closed the valve stopping the water from flowing. The employee did not turn the water off on the East side.

A coworker who was acting as the attendant outside the vault flagged down a police car and asked them to call 911. The coworker left to shut off the water main two blocks away. The fire department arrived within minutes and tried to assess the situation which was hindered since the coworker left. They pulled on a rope in the vault hoping it was an employee, but just pulled a pump out. They then saw a boot floating in the water and attempted to pull the legs out with no success. They secured the legs with a rope secured to a backhoe and worked for approximately 47 minutes to free the employee. At 12:37 pm, they removed the employee from the vault and transported him to a local level one trauma center, where he was
