The present disclosure relates to a self-contained high pressure pneumatic beverage dispensing system which includes a water pressurization and supply system. In one aspect of the invention, the water pressurization and supply system comprises a water pump having a piston cylinder and a piston that is disposed within the piston cylinder between the first and second ends of the cylinder. The water pump is adapted to be filled with high pressure gas on a first side of the cylinder through a gas inlet and further is adapted to be filled with water on a second side of the cylinder through a water inlet. In a further embodiment of the invention, the pressurization and supply system can further include a water pump control system that comprises a first piston sensor positioned adjacent the first end of the piston cylinder, a second piston sensor positioned adjacent the second end of the piston cylinder, and a water pump control valve operably connected to the first and second piston sensors and in fluid communication with the gas inlet of the piston cylinder.

[ What is claimed is:] [1.]1. A water pressurization and supply system, comprising:a water pump having a piston cylinder having first and second ends and including a gas inlet in fluid communication with a first side of said cylinder and a water inlet and water outlet in fluid communication with a second side of said cylinder, said water pump further having a piston that is disposed within said piston cylinder between said first and second ends, wherein said water pump is adapted to be filled with high pressure gas on said first side of said cylinder through said gas inlet and further is adapted to be filled with water on said second side of said cylinder through said water inlet; anda water pump control system that comprises a first piston sensor positioned adjacent said first end of said piston cylinder, a second piston sensor positioned adjacent said second end of said piston cylinder, and a water pump control valve operably connected to said first and second piston sensors and in fluid communication with said gas inlet of said piston cylinder, wherein said first piston sensor sends a signal to said control valve when proximity of said piston is sensed to cause said control valve to open to permit high pressure gas to enter said first side of said piston cylinder/and pressurize the water contained in said second side of said piston cylinder and said second piston sensor sends a signal to said control valve when proximity of said piston is sensed to cause said control valve to close and vent gas contained in said first side of said piston cylinder, thereby permitting said second side of said piston cylinder to be refilled with water.
