Abstract: At approximately 2:00 p.m. on April 3, 2007, an employee and five coworkers were working attempting to install a 60-in. by 10-ft by 0.5-in. steel pipe casing for the 42-in. regional main water line. The site was comprised of a 60-ft by 40-ft shaft which led down to a tunnel, which had already pushed the 60-in. steel pipe approximately 120-130-ft laterally under the Cypress Creek. The employee was cleaning the excess dirt from the 60-in. pipe as the pipe was hydraulically pushed inside. A breach occurred, immediately filling the tunnel and the shaft with water. All of the coworkers were able to escape except the employee. The employee was found dead on April 4 by the Houston Police Department Dive Team embedded in the silt, at the shaft end.
