A horizontally mounted submerisible pump assembly for pumping water from water storage tanks, which pump assembly is characterized by a submersible pump mounted inside a horizontally oriented tube extending through the wall of a water storage tank. A valve is provided in cooperation with the immersed end of the tube to facilitate flow of water into the tube to the pump and the opposite, dry end of the tube is closed by an adapter flange mounted on a length of adapter pipe, one end of which extends into the tube and communicates with the discharge of the pump and the other end of which is flanged to a water distribution line. The water distribution line extends to a conventional pressure tank for distributing water to multiple users on demand. The submersible pump is typically of turbine design and is sized to quickly and efficiently pressurize the water distribution system by pumping water from the storage tank and the flooded tube to the pressure tank. The tube enclosing the pump facilitates removal and replacement of the pump from the dry end of the tube without draining the storage tank.
