Replacing LADWP Aging Infrastructure—Construction of the River Supply Conduit Upper Reaches Project
Publication: Pipelines 2023
ABSTRACT
Los Angeles Department of Water and Power, the nation’s second-largest municipal water utility serving over 4 million residents, is upgrading its aging infrastructure including the existing River Supply Conduit, Upper Reach (RSC) trunk line. The existing RSC is a major transmission pipeline connecting the San Fernando Valley to the Central service zones. It was built in the 1940s and is a 51-in. riveted steel and concrete pipeline with an approximate length of 31,500 feet. The replacement project installed 28,792 linear feet of 78-in. diameter welded steel pipe by tunneling and cut and cover methods. It was originally designed as three units and constructed under two contracts. Units 5 and 6 installed a total of 15,536 linear feet, and Unit 7 installed a total of 13,256 linear feet. The project is expected to complete construction in June 2023.
