Monterey Desalination Water ProjectMonterey Desalination Water Project
Use brackish groundwater from a seawater barrier protecting the Salinas Basin, to create potable water for the peninsula
Use vertical and slant wells avoiding open ocean intakes
Discharge brines within Ocean Plan regulations because brackish sources are less salty than straight seawater
Solve the regulatory and hydraulic problems in the Carmel River, Seaside Groundwater Basin, and Salinas Groundwater Basin
Use off-grid power from bio-digested waste from the landfill
