What I claim is: 1. A system for hydraulically pumping liquid without using electricity comprising: a first reservoir at a first elevation, operatively arranged to store a first liquid; a second reservoir at a second elevation, where said second elevation is substantially lower than said first elevation, said second reservoir operatively arranged to store a second liquid; a third reservoir at a third elevation, where said third elevation is substantially lower than said first elevation, said second elevation is higher than said third elevation, and said third reservoir operatively arranged to store said second liquid; and, at least one hydraulic pump connected to said first reservoir via a first conduit, connected to said second reservoir via a second conduit, connected to said third reservoir via a third conduit, said pump operatively arranged to be powered by said first liquid when said first liquid is permitted to fall due to gravity, and said pump operatively arranged to pump said second liquid from said third reservoir to said second reservoir. 2. The hydraulic pumping system recited in claim 1 wherein said system further comprises a liquid pressure surge protection means for maintaining a substantially constant liquid pressure. 3. The hydraulic pumping system recited in claim 2 wherein said liquid pressure surge protection means is an expansion tank, accumulator, or pressure sensitive valve. 4. The hydraulic pumping system recited in claim 1 wherein said system further comprises at least one turbine connected to a conduit running between said second reservoir and said third reservoir for generating electricity. 5. The hydraulic pumping system recited in claim 1 wherein said system further comprises at least one filter connected to a conduit running between said second reservoir and said third reservoir for cleaning the pumped liquid. 6. The hydraulic pumping system recited in claim 1 wherein said system further comprises a control valve for regulating the flow of liquid through said system. 7. The hydraulic pumping system recited in claim 6 wherein said control valve is manually operated. 8. The hydraulic pumping system recited in claim 6 wherein said control valve is remotely operated from a control station. 9. The hydraulic pumping system recited in claim 1 wherein said system further comprises a sand trap connected to said first conduit for removing debris from said first liquid. 10. The hydraulic pumping system recited in claim 1 wherein said system further comprises at least one depth probe to monitor the depth of said first reservoir, said second reservoir, or said third reservoir. 11. The hydraulic pumping system recited in claim 1 wherein said second reservoir contains a conduit for delivering the liquid stored in said second reservoir out of said system. 12. The hydraulic pumping system recited in claim 1 wherein said third reservoir contains a conduit for delivering the liquid stored in said third reservoir out of said system. 13. The hydraulic pumping system recited in claim 1 wherein said system further comprises a plurality of check valves for ensuring the flow of liquid in only the desired directions. 14. A system for hydraulically pumping liquid without using electricity comprising: a first reservoir at a first elevation, operatively arranged to store a first liquid; a second reservoir at a second elevation, where said second elevation is substantially lower than said first elevation, said second reservoir operatively arranged to store a second liquid; a third reservoir at a third elevation, where said third elevation is substantially lower than said first elevation, said second elevation is higher than said third elevation, and said third reservoir operatively arranged to store a third liquid; and, at least one hydraulic pump connected to said first reservoir via a first conduit, connected to said second reservoir via a second conduit, connected to said third reservoir via a third conduit, said pump operatively arranged to be powered by said first liquid when said first liquid is permitted to fall due to gravity, said pump operatively arranged to discharge said first liquid into said third liquid, wherein said discharged first liquid and said third liquid combine to form said second liquid, and said pump operatively arranged to pump said second liquid from said third conduit to said second reservoir.
