About Poseidon Water


Poseidon is a water project development specialist headquartered in Boston, Massachusetts that identifies, develops, owns, and manages large water infrastructure projects.

With a primary focus on large-scale reverse osmosis seawater desalination plants co-located with coastal power plants, we partner with water agencies to deliver water infrastructure projects. Our partnership approach is structured to implement water infrastructure solutions in a reliable, environmentally sound way and at a competitive cost compared to new sources of potable drinking water. The company holds multiple patents for both desalination systems and the integrated treatment of brackish concentrate and seawater.
