  • Los Angeles experiences frequent breaks, with some incidents causing major flooding and damage to roadways.
  • California City has over 200 miles of aging metal pipes, contributing to repeated water main failures.
  • Causes include aging infrastructure, ground movement from droughts or heavy rains, and pressure fluctuations in the water system.
  • Breaks often result in emergency street closures, sinkholes, and service disruptions to homes and businesses.
  • Caltrans monitors and reports emergency road closures statewide, including those caused by water main breaks.
