Description
265245 / Pre-treatment and post-treatment steps may be included to treat the desalinated water prior to its delivery to the natural watercourse. All of the desalinated product water may be delivered to the natural watercourse or only a proportion thereof may be delivered to the natural watercourse with the remainder being used for other purposes.
Depending upon the topography of the natural watercourse, more than one hydroelectric power station may be provided to harness energy from the flow of water. Similarly, more than one pressure retarded osmotic plant may be provided to harness energy from the salinity gradient.
Preferably, all energy harnessed by the method and system of the present invention is delivered back to the desalination plant, although any excess may be delivered to the grid.
In a preferred embodiment of the present invention, the desalination plant is provided in the vicinity of the Mediterranean Sea and the desalinated product water is piped to the Sea of Galilee, where it flows into the River Jordan and finally reaches the Dead Sea. At least one hydroelectric power station is provided where there is a sufficient change in height for the flow of water to generate energy. The at least one pressure retarded osmosis plant is provided where the River Jordan meets the Dead Sea.
Brief Description of the Drawings.
An embodiment of the invention shall now be described, by way of example only, with reference to the accompanying drawings in which: Figure 1 is a map of a region provided with a system according to one embodiment of the present invention; Figure 2 is a graph illustrating heights above sea level in the region of Figure 1; Figure 3 is a block diagram of a system according to one embodiment of the present invention.
Detailed Description of the Invention.
The present invention provides a novel, self-sustainable method and system for revitalising natural water sources that are of a different salt concentration and located at different heights to each other. In the given example, the natural water resources are the Mediterranean Sea, the Dead Sea, the Sea of Galilee and the River Jordan located in the 4

10. A system for the re-distribution of water in a geographical region, the system comprising: (a) a desalination plant located in the vicinity of sea water for producing desalinated product water and brine from the sea water; (b) pipework to deliver the desalinated product water to a natural water watercourse to increase water levels in the natural watercourse; (c) a hydroelectric power plant located at a point of change of height in the natural watercourse to harness energy from the flow of water; (d) a pressure retarded osmosis plant located at a point of change in salinity of the water in the natural watercourse to harness energy from the salinity gradient; and (e) transmission lines to deliver energy harnessed by the hydroelectric power plant and/or the pressure retarded osmosis plant to the desalination plant (a).
11. The system as claimed in claim 10, wherein the desalinated product water is delivered to a natural water reservoir which delivers water to the natural watercourse.
12. The system as claimed in claim 11 wherein the natural reservoir is located at a greater height than the natural watercourse. 265245 /
13. The system as claimed in any one of claims 10 to 12 wherein multiple hydroelectric power plants are provided to harness energy from the flow of water, each plant being located at a point of change of height in the natural watercourse.
14. The system as claimed in any one of claims 10 to 13 wherein the watercourse terminates in a reservoir of high salinity water, the terminal reservoir being located at the lowest level relative to the rest of the watercourse.
15. The system as claimed in any one of claims 10 to 14 wherein the desalination plant is provided in the vicinity of the Mediterranean Sea and pipework is provided for delivering water from the desalination plant to the Sea of Galilee, where it flows into the watercourse of the River Jordan, the hydroelectric power station being provided where there is a sufficient change in height for the flow of water to generate energy; and at least one pressure retarded osmosis plant is provided where the River Jordan meets the Dead Sea where there is a sufficient salinity gradient to generate energy therefrom.
