Construction is set to begin on Poseidon's enormous desalination plant in Carlsbad after financing for the project closed this week. 

The San Diego County Water Authority announced that project financing for the Seawater Desalination Project closed successfully "bringing with it $734 million in tax-exempt bond financing to build the nation’s largest seawater desalination plant and a related 10-mile pipeline." 

Grading on the NRG Energy site is set to begin within days. The facility should be completed and operating in 2016. 

The Carlsbad-based facility is expected to produce 50 million gallons a day —  surpassing output at plants in Trinidad and Tobago— and is set to supply approximately seven percent of the region's  water consumers by 2020.

Building costs for the plant and pipeline — which connects to the Water Authority’s aqueduct in San Marcos — are estimated near $1 billion.
