Summary
300 cubic yards of concrete slurry went into the 25-foot-deep trench Monday after LADWP said crews resolved all issues found in pressure testing and completed checks on every section of the repaired pipeline.
17 million gallons burst from the 1916 trunk line last Thursday, and Sunset Boulevard has now been shut for six days between Sherbourne Drive and San Vicente Boulevard with no firm reopening date.
24 hours of curing, street repaving and water-quality work still remain before service can resume, including chlorination, testing to drinking-water standards and dechlorinated discharge into storm drains.
547 miles of trunk line run under Los Angeles, much of it nearing the end of its useful life, making the Sunset rupture a fresh sign of the city’s aging water infrastructure.
