Overview

  • Crews have excavated nearly 25 feet and are hand-digging around oil pipelines, a fiber-optic line and a gas line to reach and replace the damaged 54-inch valve.
  • LADWP now aims to restore full service by 3 a.m. Monday, contingent on residents stopping all nonessential tap usage to rebuild system pressure.
  • A boil-water advisory remains in effect across both communities due to contamination risks after prolonged pressure loss in the distribution system.
  • On Saturday a temporary pipe coupling burst at a repair site, flooding a Granada Hills home and prompting further damage assessments.
  • The department has expanded emergency sites offering bottled water, showers and laundry facilities to support more than 9,200 affected households.
