Historic First Aqueduct Rehab Project Begins
Water Authority crews successfully completed the first of three coordinated shutdowns of the First Aqueduct in early March to launch a major renovation of dozens of structures on two pipelines, including the historic Pipeline 1 that delivered imported water to the region starting in 1947. The series of shutdowns was carefully planned for nearly four years to minimize impacts on the community and retail water agencies. Started during the Water Authority’s 75th anniversary year, the $47 million First Aqueduct structure and lining renovation project – including a $30 million construction contract - is among the most complicated pipeline retrofits in agency history. Upgrades to the pipeline include replacing the lining on the steel pipe sections; removing 19 associated structures; and retrofitting 41 structures – all without jeopardizing water service to the region.
“The First Aqueduct has been a very reliable source of imported water for more than 70 years. These critical upgrades will make sure we can operate and maintain the pipelines for another several decades to transport water to the region for future generations.”
