ORIGINAL POST: At approximately 2:00 AM today, a 10-inch water pipe broke in the vicinity of 4100 MacArthur Blvd, near the corner of MacArthur and Von Karman in Newport Beach.

IRWD crews responded immediately to the site and began working to find and isolate the broken section of pipeline, minimizing the loss of water. Water from the break flooded a nearby parking structure and crews are currently in the process of pumping out the flooded areas.

The water has now been shut off to the site and repairs to the pipeline are expected to begin soon. Repairs are expected to be complete at approximately 11:00 AM. Three out of the four adjacent traffic lanes are currently open.
