<p>Water is removed from an underground perforated pipe (14) by a submersible pump (20) inserted into an imperforate pipe (12) extending from above ground to below ground level for communication with the perforated pipe (14). An inflatable bladder (32) seals the submersible pump (20) to the inner wall (13) of the imperforate pipe (12) for facilitating suction of water from the perforated pipe (14) into the imperforate pipe (12). Water is drawn into a proximal end of the pump (20) and expelled out of a distal end of a pump, and out of the imperforate pipe (12) above ground level. By sealing the pump (20) to the inner wall (13) of the imperforate pipe (12), the pump (20) is capable of drawing water from an underground perforated pipe located at a depth greater that the pumping capacity of the pump (20) for drawing up water.</p> |
