The Carlsbad Project is the Largest Desalination Plant in the nation and a Complete Game Changer for Desalination in the US.
The award-winning desalination project owned and developed by Poseidon Water, will provide the San Diego County Water Authority (SDCWA) with enough water to serve more than 300,000 people and generate over $50m annually to the regional economy. The plant overcame significant practical, regulatory and economic hurdles to deliver a cost effective and environmentally friendly water supply. Poseidon Water, IDE and its partners worked for more than 10 years to develop a desalination solution that meets all the challenging criteria.
