Westwood/Sunset Water Trunkline Break Update
|Los Angeles Department of Water and Power (LADWP) crews continue to work at the scene of the water trunkline break that occurred yesterday at approximately 3:30 p.m. on Sunset Blvd., west of Hilgard Ave in Westwood. As of last night at 8pm, it appeared that the trunkline was fully isolated; however, water flowing from the line continued at a rate that continues to fill the work area, preventing repair work from beginning. The water flow is the result of valves in the trunk line that have not been able to be fully closed. Crews estimate the valves are approximately 95% closed, but will not turn further, consequently, the rate of water flowing through the pipe and draining into the work area is still too high to begin work.
LADWP water system engineers are developing alternate solutions to get the water shut off as quickly as possible.
The water shutoff and succeeding repairs will be complex as the trunkline break occurred at the juncture of two water trunk lines that meet in the shape of a Y. The break appears to have damaged the juncture, the 30 inch steel riveted pipe and possibly the pipe that connects into it, right at the juncture of the two pipes. Currently, water continues to flow to the work site, preventing crews from further excavating and initiating repairs.
Given the current status and complexity of the repair, LADWP currently estimates that Sunset Blvd will not reopen today or tomororow. A better estimate will be possible as crews make more progress.
More information about the rate of repair will be provided as soon as it is available at www.ladwpnews.com and on Twitter: @LADWP.
Motorists are urged to asked to stay away from the area, and take alternate routes.
