Abstract

A water pumping system used for lifting liquids in vertical or near vertical conduits or pipes to a higher elevation at a reduced energy cost. Also, the water pumping system can be used to circulate water between upper and lower elevations to generate hydropower energy at a lower energy cost. The water pumping system includes a water pump, air blowers, an air supply chamber, a lift conduit, a return conduit, a flotation device separation chamber, a plurality of floatation devices, one or more flotation device pushers, a dehydration unit, and two water storage tanks. The lift conduit and return conduit creating a continuous loop in which the flotation devices can circulate and act as a piston in the lifting conduit to elevate the water to higher elevations with reduced energy. The floatation devices include spacer rings and spacer rods. The floatation devices are inserted inside the lift conduit and the return conduit.
