Abstract
An irrigation system comprises a pump facility 11 for pumping up seawater from the sea, an artificial seawater lake 31 formed in an inland area, a freshwater producing plant 41 for producing freshwater from seawater, an artificial freshwater lake 51, and an irrigation canal 61 for supplying the freshwater to a projected irrigation area. A solar-cell power generation plant 21-25 is constructed for supplying electric power to operate the irrigation system. The irrigation including the artificial seawater lake is formed in an inland area in a comparatively short time, and freshwater is produced from the seawater stored in the artificial seawater lake. Therefore freshwater can be supplied to a projected irrigation area at an early stage of the construction of the irrigation system.
Claims10
An irrigation system, comprising:
- a pump facility for pumping seawater from a sea;
- an artificial seawater lake formed in an inland area for storing said seawater pumped up by said pump facility, said stored seawater being exposed to sun and wind to partially evaporate and to thereby increase local atmospheric humidity;
- a freshwater producing facility for pumping up said stored seawater from said artificial seawater lake and for producing freshwater from said seawater, said freshwater producing facility being located closer to a projected irrigation area than is said artificial seawater lake, the location of said freshwater producing facility being selected to enable convenient storage of salt produced by extraction of fresh water from seawater processed thereat;
- and
- a freshwater supply facility for supplying said freshwater produced by said freshwater producing facility to said projected irrigation area.
An irrigation method, comprising the steps of:
- (a) constructing a pump facility for pumping seawater from an a sea;
- (B) forming an artificial seawater lake in inland area for storing said seawater pumped by said pump facility so that said stored seawater is exposed to sun and wind to partially evaporate to increase local atmospheric humidity;
- (c) constructing a freshwater producing facility for pumping said seawater from said artificial seawater lake and for producing freshwater from said seawater, said freshwater producing facility being located closer to a projected irrigation area than is said artificial seawater lake, the location of said freshwater producing facility being selected to enable convenient storage of salt produced by extraction of freshwater from seawater processed thereat;
- and
- (d) constructing a freshwater supply facility for supplying said freshwater produced by said freshwater producing facility to said projected irrigation area.
