A method of designing an optimized seawater pumping apparatus, using a computer in a system in which a seawater pumping apparatus including a pumping pipe and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe is installed to reduce seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, includes applying an optimization algorithm to initial condition data of the aquifer to generate n decision variable sets of the seawater pumping apparatus, applying an underground water flow model to each of the n decision variable sets to generate n prediction results of change in the seawater-fresh water boundary surface, calculating a performance evaluation value of each of the n prediction results, and selecting a decision variable set having a maximum performance evaluation value, where n is an integer and equal to or greater than 2.

Disclosed is a non-powered seawater pumping apparatus for reducing seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, the apparatus including a pumping pipe having opposite open end portions, a first end portion of the opposite open end portions being positioned below a sea level and a second end portion being positioned below a seawater-fresh water boundary surface in the land, and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe, which is buried in the land, so as to space away the land-buried portion of the pipe from the land, wherein seawater is filled in the pumping pipe, and the well includes a screen having a plurality of through holes formed along a circumference of the well at a lower end portion of the well.

An odor venting water pump system uses an air pump to agitate well water within a well enclosure in order to separate unpleasant smelling gases from the well water. A water pump is positioned at the bottom of a well enclosure and surrounded by well water received into the well enclosure from the surrounding ground water supply. An air tube is connected to an air pump and a terminal end of the air tube is positioned at the lower end of a venting pipe which has an inlet to accept well water. The pumped air agitates the water within the venting pipe and pushes the air/water mixture upwards through the venting pipe to an outlet, where the water returns to the main water supply while the odious gases are free to exit the well enclosure through an air vent at the upper end of the well enclosure.

A method for the desalination of water, carried out in one embodiment on the basis of a borehole (4) in permeable coastal land, in which two internal wells (5, 6) are interconnected at the bottom, by means of a membrane packet (9), disposed such that the supply flow provided via the borehole (4) flows in a downward direction by the suction of a motor pump (7) installed at a shallow depth inside the well (5), with an ascending flow, pouring same to the marine outlet and the diluted flow (permeate) drains from the membrane packets (9) to the second well (6), which is hollow and at atmospheric pressure, where a motor pump (8) extracts the permeate for the use thereof, while in another embodiment the membrane packets (15) may be disposed in ducts hanging from a floating platform anchored in the sea or other salty water.

A portable pump system for use over a wellbore, the system having a utility trailer with a trailer bed and two wheels, a reel around which is wound a length of flexible pipe, an array of solar panels, a submersible pump, front outrigggers extending laterally from opposite sides of a front end of the trailer bed, and rear outriggers extending laterally from opposite sides of a rear end of the trailer bed. The reel is situated at a rear end of the trailer bed. The array of solar panels is situated in the front half of the trailer bed. The submersible pump is attached to a distal end of the flexible pipe. The array of solar panels is configured to supply power to the submersible pump. The reel is mechanically coupled to a sprocket system situated on top of the trailer bed and adjacent to the reel.

A well water system includes a pressure switch adapted to monitor air pressure within a pressure tank, rather than water pressure within plumbing. The pressure switch is connected directly to the pressure tank by a tank adaptor in fluid communication with the pressurized air inside the tank. With the tank adaptor directly connecting the pressure tank to the pressure switch, the pump is actuated based on air pressure changes within the tank rather than water pressure changes in the plumbing. The pressure switch is calibrated to activate the pump when the air pressure within the pressure tank drops below a predetermined pressure, which correlates to a certain water pressure within the system. When the air pressure within the pressure tank is restored to a predetermined maximum, the pressure switch deactivates the pump having filled the tank to the desired maximum water threshold.
