Optimization of subsurface intake designs for seawater desalination facilities

Subsurface intakes are increasingly used for raw water supply to seawater desalination facilities because of their reduced overall costs and environmental footprints. The technical challenge for using subsurface intakes lies primarily in finding the optimal, system-specific solution that provides the required volume of water and meeting water quality objectives. A foundation for subsurface intake evaluation and design is a detailed hydrogeological and geochemical characterization of the project site area. Numerical groundwater flow and geochemical modeling, based on site-specific hydrogeological data, can then be used to evaluate various design options.
