Water Quality Testing in Progress to Bring Water Line Back into Service
LOS ANGELES, CA (July 22, 2026) – Los Angeles Department of Water and Power (LADWP) crews are preparing to pour asphalt this evening following completion of the 24‑hour curing window of the slurry backfill and the compaction of a concrete aggregate base, marking a major milestone toward safely reopening Sunset Boulevard at the site of the water pipe rupture in West Hollywood. The asphalt will dry overnight, after which LADWP will begin street striping in the morning along with cleanup and other preparations necessary for the full street reopening of Sunset Boulevard, now in sight for late Thursday or Friday of this week.
As the current street repairs progress, LADWP’s water quality team is preparing to conduct water quality testing to ensure all standards are met before the repaired 36‑inch pipe is returned to service. The new section of the pipe has been disinfected and is now filled with water that is currently being isolated and held in preparation for water quality testing. Once test results confirm the water inside the repaired section of the pipe meets water quality standards, the trunk line can be returned to service as early as Friday.
LADWP continues to assure customers that water remains safe to drink and there are no service interruptions expected as this work approaches completion. Customers are still urged to conserve water to help avoid low-pressure periods during high demand.
