IDE selected to develop Harbor Island 100 MGD desalination facility in South Texas
The project is designed to deliver 100 million gallons of water per day to South Texas, and will be the largest seawater desalination facility in the Western Hemisphere.
IDE Technologies announced it was unanimously selected by the Nueces River Authority Board to develop the Harbor Island Desalination Facility. The project, which is designed to deliver 100 million gallons of water per day to South Texas, will be the largest seawater desalination facility in the Western Hemisphere.
“Backed by IDE’s proven innovation in water technology, the Harbor Island Desalination Facility will solve a critical water need in South Texas and help to diversify and strengthen the overall water supply,” said Lihy Teuerstein, CEO, IDE Water Assets. “We are proud to partner with the Nueces River Authority and be part of developing a record-breaking facility and setting a standard for future projects in the US.”
IDE will leverage its modular desalination design approach for the Harbor Island Desalination Facility, allowing for major plant components to be manufactured and assembled in phases to reduce the timeframe from initial construction to water production. Once in operation, the project will support municipal and industrial water use, and play a critical role in future-proofing South Texas’ water supply.
“IDE was the clear, standout choice to lead the development of this significant water infrastructure opportunity,” said Eric Burnett, Nueces River Authority Board President. “By partnering with IDE Technologies, the Nueces River Authority is advancing a globally proven solution designed to strengthen long-term water reliability and economic resilience for generations.”
This project is a clear example of the increasing need for seawater desalination in drought-stricken regions, highlighting IDE’s unique ability to resolve long-term water supply challenges in the Gulf Coast region and beyond.
