Abstract: Applicant's preferred embodiment utilizes municipal waste water effluent to replenish a depleted geothermal field. Condensate produced by expanding steam produced in the geothermal field through a steam turbine-generator is pooled with cooked water collected from the field, and then directed through a penstock from a higher elevation to a lower elevation where further energy is extracted through a traditional hydroelectric generator. The cooked water and condensate may be treated to produce potable water and/or distributed for public consumption either before or after it is directed to the hydroelectric turbine generator. The effluent is pumped up to the geothermal field during off-peak periods of electric consumption, and hydroelectric power generation is accomplished during periods of peak electric demand. A fraction of the effluent may be used as cooling water for the steam turbine and its associated condenser before injection into the geothermal field.
