Method and apparatus for desalinating water combined with power generation

A co-generation system, comprising:

• at least one power generation turbine for generating electricity for a power grid, wherein said at least one power generation turbine has a heat source;
• a brine handling area further comprising at least one desalinating train having at least one distillation stage coupled to said heat source for distilling product water from seawater to make potable water
• wherein said at least one power generation turbine, said handling area and said at least one desalinating train are located inland and above-ground;
• at least one substrata seawater table supply well for pumping substrata seawater from a first non-inland location and below a fresh water aquifer and substrata barrier for processing by said at least one desalinating train, said at least one substrata seawater table supply well positioned underground and having a proximal end and a distal end, wherein said proximal end is operatively connected to said brine handling area and said distal end is positioned at said first non-inland location and below a fresh water aquifer and substrata barrier;
• and
• at least one substrata seawater table discharge well for re-injecting a brine effluent from said at least one desalinating train into the substrata seawater table, said at least one substrata seawater table discharge well positioned underground and having a proximal end and a distal end, wherein said proximal end is operatively connected to said brine handling area and said distal end is positioned at a second non-inland location and below a fresh water aquifer and substrata barrier, to re-inject the brine effluent into said second non-inland location and below a fresh water aquifer and substrata barrier,
• wherein said first non-inland location of said at least one substrata seawater table supply well is a distance from said second non-inland location of said at least one substrata seawater table discharge well such that the substrata seawater pumped by said at least one substrata seawater table supply well for processing does not include the brine effluent re-injected by said at least one substrata seawater table discharge well, and
• wherein said co-generation system thereby establishes an exchange of the substrata sea water from said first non-inland location collection site to said second non-inland location re-injection site, and by avoiding depletion, provides for a continued availability of seawater resources from said substrata sea water to make subsequent potable water.
