Turning seawater or brackish water into affordable fresh water, 24 hours a day, without the use of expensive energy. The off-grid solution directly uses solar, wind or wave energy to fill a buffer tank on a hill with seawater. Through the force of gravity, the reverse osmosis process receives its required feed: pressurized seawater. The system configuration makes sure the water buffer always contains water to enable constant water production, resulting in lowest cost of water. The waste energy of the reverse osmosis process is reused to reduce the required elevation with 80% to 90 m or 290 ft for seawater.
The buffer tank can be easily constructed using a corrugated, galvanized, coated steel tank with liner that is suitable for corrosive environments. A concrete cistern or basin are suitable alternatives.
This uses the forces of nature at its best for an independent guilt-free water supply. By avoiding energy conversion losses, batteries & frequent maintenance, savings up to 70% can be realized. The bigger, the better, as water cost comes down with the size of production. Sizes start small and go up to millions of liters per day.
