The Carlsbad Desalination conveyance pipeline is a 10-mile, 54-inch water delivery pipeline that will travel eastward from the seawater desalination plant through Carlsbad, Vista and San Marcos to the San Diego County Water Authority’s Second Aqueduct connection facility in San Marcos. Construction on the desalination plant began in late 2012. The first segment of the pipeline construction is currently under way in San Marcos at Rancho Santa Fe Road. In May work will start on W. Linda Vista Drive from Las Flores Drive toward Poinsettia Avenue and continue Southwest on Poinsettia Avenue.

The first phase of construction in Carlsbad will also begin in May on the Southwest corner of Cannon Road and Avenida Encinas. On September 3, the next phase of construction on Cannon Road will begin at Paseo Del Norte and travel east. The pipeline and plant are scheduled to be completed and in operation in early 2016.
