Great Conduit Breaks Record. Largest Pipe Line Built by Los Angeles. Engineering World Astonished by a Work Eclipsing That of Government Reclamation Service. Los Angeles Herald | February 11, 1910. The largest concrete pipe line in the world in diameter is being built as a part of the Owens river aqueduct one and one-half miles southeast of Newhall near the Southern Pacific railroad tracks. Hitherto the government reclamation service has been the pioneer in the construction of the biggest pipe lines in the country, but Los Angeles has broken the record and astonished the engineering world. It has not been decided to what length the pipe will be built. So far it has been constructed a distance of 908 feet. The thickness is nine inches reinforced by steel bars three and one-quarter inches thick and spaced four inches from each other. When completed it is said it will carry 280,000 gallons of water in twenty-four hours. It is expected the line will be completed within sixteen months when it will be inspected by the aqueduct engineers. The pipe is being constructed piece by piece on the grounds. It is known as the Whitney siphon pipe. O.P. Cox, construction superintendent of the aqueduct work, formerly of the Boston aqueduct, is superintending the building of the pipe.
