10-mile project stretches from Carlsbad to San Marcos
After two years of work, the 10-mile pipeline that will carry fresh water from the Carlsbad Desalination Plant to a regional water distribution plant in San Marcos is complete. Crews installed the last 54-inch diameter pipe, No. 2177, into Macario Canyon in Carlsbad on June 29.
The project is on budget and on schedule, pending approvals for state regulatory agencies, to start delivering desalinated water to the area this fall. The plant will produce an estimated 50 million gallons of water per day, enough to serve about 112,000 families and meet 7 to 10 percent of the region's water demand.
The plant will offer a new source of water that is drought-proof, locally controlled and reduces dependence on water imported from Northern California and the Colorado River.
"This final piece of pipe is a significant milestone for the Carlsbad Desalination Project, and a sign that the entire construction project is entering its final phase," said Peter MacLaggan, vice president of
Poseidon Water, the project's private developer.
"We are grateful for the cooperation and support of the businesses, residents, property owners and city staff along the route in Carlsbad, Vista and San Marcos," MacLaggan added.
With the pipeline installed, construction has shifted its focus on restoring streets between Vista and the desalination plant in Carlsbad and finishing the plant.
The $1 billion Carlsbad Desalination Project is the result of a 30-year water purchase agreement between the San Diego County Water Authority and Poseidon Water for the purchase of between 48,000 and 56,000 acre-feet per year of desalinated seawater. It includes three main components: the desalination plant, the pipeline, and about $80 million in upgrades to Water Authority facilities for distributing the desalinated water throughout the region.
During the three-year construction process, the project is supporting an estimated 2,500 jobs and infusing $350 million into the local economy.
