A system for raising water from an underground source of water to an aboveground tank includes a plurality of capillary tubes for raising water from the underground source to a first water level, a pipe for raising water from the first water level to an above ground tank, the aboveground tank is painted black to absorb the sun's rays and is tilted with an elevated proximal end so that water in the tank runs down to its distal end. A tap is provided in the distal end for drawing water out of the tank. The tank also includes two one way valves, one in an upper portion of the distal end for allowing heated air to escape and one in a lower portion of the distal end to allow water to be drawn up into the tank as heated air cools. A solar powered rechargeable battery can be used to power a positive displacement pump.
