Abstract
Abstract Water is removed from an underground perforated pipe by a submersible pump inserted into an imperforate pipe extending from above ground to below ground level for communication with the perforated pipe. An inflatable bladder seals the submersible pump to the inner wall of the imperforate pipe for facilitating suction of water from the perforated pipe into the imperforate pipe. Water is drawn into a proximal end of the pump and expelled out of a distal end of a pump, and out of the imperforate pipe above ground level. By sealing the pump to the inner wall of the imperforate pipe, the pump is capable of drawing water from an underground perforated pipe located at a depth greater than the pumping capacity of the pump for drawing up water.
