  • Patent number: 4248305
    Abstract: A system and method of moving near-surface water to a deep water aquifer at a high rate of transfer and with no external energy sources, and which additionally generates excess energy available for other uses. The system comprises at least one deep well into the deep aquifer and one or more shallow wells into a near-surface water table aquifer having siphon pipes from the shallow wells to the deep well. Siphon action is initiated resulting in a continuing flow of water from the shallow wells to the deep well. A water-driven turbine is disposed in the deep well above its tail water level and below the lower end of the siphon tubes. The water flow operates the turbine and the turbine shaft drives an external vacuum pump. Each shallow well has a closed top plate, and suction from the vacuum pump is applied through the top plate, holding the water level above its normal point increasing the draw down.
