A leak was discovered at SONGS in a precast 18-foot diameter discharge pipe. C&W Underwater Engineering and Construction of National City, California surveyed the pipe and discovered a joint and a crack. This area produced a leak that was a mixture of water and air. Frank Zepeda, Project Manager for SONGS JWI for a solution. JWI produced a technical paper outlining the procedures to be used and submitted this along with the proposal.
After supplying equipment and materials, JWI technicians advised C&W divers on the injection process. JWI then monitored C&W’s application of the underwater injection process via television imagery.
Due to the joint effort of C&W and JWI, the project was completed on schedule with no evidence of air or water leakage from the discharge pipe.
